Someone walks into the ER with intractable hiccups. One of the questions the emergency room physician should ask is, “Have you been eating star fruit?”

In my video cautioning about oxalate-rich foods, I talked about star fruit nephrotoxicity—kidney toxicity. “…[E]xcessive consumption of star fruit has been associated with the development of oxalate [kidney damage].” Less than a cup of star fruit juice or three whole fruits—they’re not that big—can result in “acute star fruit nephrotoxicity.” “…[I]ngestion of even modest quantities of star fruits can produce” kidney problems;  so, it is essential to educate the public to avoid consuming star fruit, “especially on an empty stomach or in a dehydrated state” to prevent star fruit nephrotoxicity.

But what about the neurotoxicity? We’ve known for more than a quarter century now about the neurotoxic effects, but few seem to be familiar with the syndrome. It starts, most commonly, with hiccups, but then can rapidly worsen, especially in those with compromised kidney function to start out with. Why? Because the “fruit contains a powerful neurotoxin that can accumulate in blood, cross the blood–brain barrier…, and eventually cause irreversible [brain] damage.” The toxin itself, named caramboxin, is normally excreted by the kidneys; and so, is especially toxic to those with renal insufficiency—compromised kidney function—so much so that for those with severe chronic kidney disease, a single star fruit can put someone in seizures within three hours, a coma, and then death within three days.

In a series of about a hundred cases of toxicity, consumption ranged between just a half of a star fruit up to 50, with an average of about four, but most of those had some sort of pre-existing kidney disease. The average number of star fruits eaten by the normal kidney function group before their toxic dose was more like 15. So, people with normal kidney function may be more likely to suffer from kidney damage than brain damage, which starts at down around four star fruit.

The bottom line is that those with chronic kidney disease should avoid star fruit to avoid severe intoxication. In Brazil, where the fruit is popular, there are actually laws to alert people about the risks.  Because of the neurotoxins, star fruit should be prohibited for patients with chronic kidney disease, and even those with normal kidney function may want to avoid the fruit. Just something to think about, before you reach for the stars.

    1. Some fruits are more or less toxic apparently but often if unripe, theses fruits normally all have a bad and bitter taste, often extremly bitter, bitter and too acidic is a sign of toxicity by nature but sweet and salty(not too much) taste gives the green light when natural, good for us.

      I dont think a single good to delicious significant toxic fruit does exist especially if ripe but unripe fruits are not good anyways and often at least bitter and/or acidic again.

      1. Actually, wild oranges, which grow in florida, are very acidic, but still good for you. And many bitter foods are very healthy. Can’t judge by that.

        1. But the bitterness still shows the presence of significantly toxic compound/alkaloids like theobromine and similar in chocolate or caféine in coffee which is a natural pesticide(obviously toxic, it is a psychoactive drug) made by the coffee beans plant.

          1. Julot, you say this kind of stuff all the time and offer no actual evidence but there isn’t evidence to what you’re claiming, it’s nonsense. In REALITY some of the healthiest foods and beverages on the planet are bitter or acidic e.g. hibiscus tea, cocoa, dark green leafy vegetables, orange peel, lemons, etc. etc. etc…. It gets tiresome. Things that act as natural bug deterrents in a plant are not all toxic things in fact, these, such as sulforaphane, are some of the healthiest compounds we can put in our bodies.

            1. You need evidence to prove the sun is really hot or water is liquid? I mean, that simple fact and not non sense just like caffeine is a pesticide ( -CIDE) and a psychoactive drug like it or not, i’m sure you have no problem with the fact nicotine is a pesticide and a psychoactive drug, the only difference is you probably dont smoke but you are probably drinking cafeine beverage(coffee/tea) or eat chocolate, peoples like to hear good news about their bad habits but not the opposite again.

              Orange peel are healthy or even a food? Feel free to eat a meal of it and see what happen and how you feel after, thats some weird healthy food you only want to eat in tiny amount…

              1. Julot, you sound insane. Yes, you need evidence to make scientific assertions–like it or not. And in fact, yes, you do need evidence to prove that the sun is hot or that water is a liquid, it is in the evidence of it that we came to such conclusions and in cases like that, it just so happens that the evidence is right in your face so it doesn’t take controlled studies to have realized it.

                This is an evidence based site, you adamantly making claims about your own beliefs without having any evidence to back it up except your personal perception of things isn’t exactly how it rolls here–which is why this site is relevant. There are plenty of blogs out there you could be taken seriously on but honestly, that kind of misinformation is already polluting the internet and minds, so, I would urge you to start thinking in terms of evidence based especially before you go telling it like it is.

                Yes, citrus peels are actually incredibly healthy. I have eaten the entire peel along with my orange, felt fine; felt great. Dr. Greger has spoken about the EVIDENCE of the health benefits of citrus peel.

                1. It seems like you just learned cafeine was a psychoactive drug and a pesticide similar to nicotine present in milligrams amount in a cup of coffed/tea(traces of pesticides on foods are present in micrograms amount and most peoples freak out because they are so clueless), thats interesting…ask toxicologists what the bitter taste means in nature, every mushrooms are toxic, the so called edible ones are just significantly less toxic than others ones.

                  I think If anything must be eaten in moderation or sparingly, it should not be eaten at all for optimal health.

                  1. Julot, you’re out of your mind. You don’t belong on a science based website, you belong on some ridiculous blog somewhere misleading people prone to believe anything and weirdly alter their lifestyles based on childish fiction rather than evidence. You seem to tirelessly want to go on and on about this, so I’ll leave you the last word lest I visit back for who knows how long for no productive reason.

                    1. What is funny is there is organic coffee and tea wich contains a significant amount of caffeine which certainly is a pesticide(100% science and toxicology based) haha, this nonsensical world we lives in, doesnt make more sense that cigarettes and even alcohol are allowed to be sold in almost every countries in the world…

          2. Julot,

            Some antioxidants aren’t actually antioxidants but rather activate metabolic mechanisms that have the antioxidant action. Those substances are believed to be insecticidal and present in plants as a defense. Many healthful foods are initially offensive such as garlic, hot peppers, mustard seeds, horseradish, radish, ginger and pepper. So blind hedonism is outclassed by epicurians who will mix food items in recipes to produce superb flavor while also creating a healthful diet. Stoicism is also often superior to simplistic hedonism at promoting healthy living.

            Sugar of lead makes wine taste better but it is decidedly bad for people. Lead paint chips taste like candy. That’s why they are so dangerous because children are often simple hedonists.

            1. Wrong exemple because i was talking of natural substances/food/drink not artificially man made, peoples shlould just try to eat fermented foods in nature, they would see if they like it and would eat it in any significant amount and if thats tasty like alcohol and anything else.

        1. Fruit isn’t toxic when not fully ripe, in fact some beneficial enzymes are higher in certain fruits when they’re not fully ripe. Green bananas actually are an excellent source of resistant starch and they make flour out of them. But people tend not to eat unripe fruit, naturally, because it tastes horrible so even so, there isn’t a lot of concern about people eating unripe pears and so on.

              1. I talked about natural foods/drinks normally raw because cooking is the first step of processing(like it or not) and bitterness and excess acid not just tasting bad because it is subjective, cupcakes doesnt grow on trees, we are a frugivorous specy, not herbivore(grass eaters), remember.

          1. I agree with julot lol you are saying he sounds insane for trusting his tastes for toxins but you are the one eating orange peels and green bananas lmao go try an unipe ackee if unripe fruits arent toxic.. its a good thing you dont live around those or you wouldnt have survived to be here today.. gosh I wonder what else youve stuck in your mouth and havnt spat out.. you and those broken instincts..

            1. is it ripe tho, what a childish response. You can agree till you’re blue in the face, but that doesn’t change the fact that it’s utter nonsense. It’s called science, that’s what the website is about so it surprises me you seem so unfamiliar with it being that you’re here.

              AGAIN, the SCIENCE shows us that citrus peel is not only edible and safe, but extremely healthy for us… so whose instincts here are lacking if that’s what you want to go on? Green bananas are used by a great number of people, you can buy the flour at any health food store just about. I’m sure some things are not good to eat unripe probably mostly due to upsetting your stomach and things like that, but fruit comes in many variety. You have to cook elderberries in order to make them safe to eat, for example, this does not mean that all fruit is toxic unless cooked.

              Why come to this site if you don’t actually regard the scientific method and learn from the information Dr. Greger presents in his videos…

              Misinformation dumbs down society and even harms so really guys….

              1. you are something else.. i think all those toxins have got to your brain.. you cant rely on science when Doctors like Pamela Popper disagree with everything Dr Greger says and she backs it up with her own science and actually teaches people how to spot faulty science for a living.. there is a legit study to prove every point.. besides the study didnt mention if the star fruit was even ripe.. ackee can also kill you if it is picked and eaten before its ready.. yet its still jamaicas favourite fruit.. so its faulty science.. and well miss appeal to science where is all your science to prove that humans cant trust our taste buds for toxins like every other animal in the world does? maybe you come from thousands of years of living in cities and youve simply lost the plot? 200 years ago my ancestors were living off the land.. and if we couldnt trust our taste buds wed all be dead lol.. they cook green bananas btw.. if you eat raw green bananas, you were probably dropped on your head as a baby and have some mental issues.. cooking helps over ride alot of bad things.. but not always.. good to know that if we were in nature you would be the one to gobble down a deathcap mushroom and chew on some unripe ackee and kill yourself.. like i said before.. i wonder what else youd eat.. science says you can get b12 from eating your feces so you probably do that aswel i imagine.. i mean saves poppin pills.. but thats pretty disgusting of you lol

                1. Jaden, who is obviously the same person as Julot and very most likely is it ripe tho, as well… I did not read past the first 1 and a half lines of what you wrote because I value my time, I did get up to the part with “her own science” and thought I should point out–though I’m sure it will be lost you Julot/Jaden/is it ripe tho–that there is no such thing as someone’s “own science.” Science is science, evidence is evidence. Fake science is when people do indeed come up with “their own ‘science.'”

                  Enjoy yourself.

                  1. you are truly insane.. no we are not the same people.. get a life seriously.. this website would be better off without you.. all you have done is come on here and argue against common sence.. and say “science tho” but then when you are asked to provide science you whine and say “i dont do my own research nerr nerr nerr” and on top of all that.. you cant even figure out how to peel an orange so you just eat the skin.. you like arguing huh? well go argue with some idiots somewhere else and waste there time.. unlike you.. some of us are here for answers from the OP.. not from some wierdow who eats green bananas and shoe laces.

              2. Again natural unprocessed elderberries (raw state obviously) are significantly bitter and the more ripe the less bitter it is, for reasons.

                Thats not childish because you dont agree based on your ignorance but most peoples dont know what a really ripe banana and most ripe fruits looks like(not opinion based but based on sugar and starch content) and eat them too unripe.

                Try a whole meal of green bananas and see how you feel idk…not just one even if many people already get discomfort with one even if they dont make the link.

                1. green bananas make your mouth feel fury that should be a good enough reason to know that something isnt right.. ideally if you wanted to be safe in a perfect world full of fruit (doesnt even really exist to my knowledge except peoples fruit collections of farms) then you would only eat what is delicious and delicious only and you would be rewarded with health and safety, science wont prove that for you tho its all instinctual thinking in an ideal world

            2. Indeed, eating citrus peels/most fruits peels and chewing fruits seeds is non sense, citrus peels contains a significant amount of a natural pesticide limonene which is well known in toxicology to be toxic, irritant, flamable(eating this?), narcotic and more but feel free to eat it but i guess i’m insane.

              Again If anything must be eaten in moderation or sparingly, i think it should not be eaten at all for optimal health and it doesnt mean i follow it 100% because life but i still think it and i have the right to~

              1. nice to see another wannabe fruitarian in the comment section like myself haha, i too feel like we should be able to trust our instincts, i know Dr greger says no salt, but Pam popper says if we dont eat enough sodium from actual salt we are at risk of stroke or heart attack, she backs it with science aswel, shame because shes usually on the other side of the argument saying we dont need this and that, she told me a fruitarian diet isnt deficient in anything but then told me we need extra salt so to be honest i dont trust any of these doctors or there science anymore, how can you trust science when there is a legit study to prove opposite claims? these people who fall so hard on science are clueless it seems.. and pam says we have salt receptors so we seek salt but for all we know the only reason we have salt receptors is so we can tell the difference between drinking water and brackish or salt water.. who knows what the hell is right these days, just like this video by Greger.. if it doesnt mention if the star fruit was ripe.. why would he make a fear mongering video about it lol to scare people and make them think we need to buy his books? all these “doctors” are selling stuff so no1 will admit they are wrong.. if only we could lock pam and greger in a room with a computer each and have them argue it all out so we could see how faulty science really is.. the fact there are long term fruitarians just proves that all nutrition science is wrong anyway, we need these things to be adressed

                1. Really Pam Popper said it about salt? i’m surprised, i watch many of her videos, i like her rigorous work with studies and i agree on most of what she are saying, do you have a link please? thx to share theses infos~

                  Well for big topics based on hundreds or thousands of studies like the benefit of fresh ripe fruit and cooked vegetables to health or the harmfulness of saturated/trans fat and dietary cholesterol, we are probably very close to the truth if not completely but for topics based on only few studies like on cafeine/theobromine(that is certainly a potent pesticide and psychoactive drug present in milligrams amount in a cup again so there is something very wrong) and as many that says the opposite like the benefit of eating irritating fruit peels and seeds, you have to follow if this makes sense or not, you can find studies showing cigarette have some benefits…

                  Here some toxicology facts about caffeine:

                  https://study.com/cimages/multimages/16/2014-11-18-side_effects_caffeine.jpg

                  And the so called benefits(lets say they are true and thats possible like every drugs can do it…)but only for unhealthy people imo not getting enough sleep/carbs/rest/excercise and others unhealthy factors and eating a significant arteries clogging diet, could be similar effects to nuts consumptions…

                  https://qph.fs.quoracdn.net/main-qimg-2771d5cdf940cdbd52ff035f22578a6d.webp

                  1. https://www.youtube.com/watch?v=ehwt7NcJofk, btw, it would also be impossible to get enough iodine, selenium and zinc on a fruitarian diet, any less than 150 grams of iodine and you grow a goitre.. just like grass fed animals on deficient soils.. we might actually need to eat seaweed as vegans to get enough iodine which is annoying to me cause i was heading for fruitarianism untill i quit weed and actually did my research [https://www.bing.com/th?id=OVP.DXSdEZkvVLDfhCf6kyVVMwEsDh&pid=Api] How Much Salt Is Too Much How Much Is Too Little AND Another Useless Osteoporosis Drug How Much Salt Is Too Much? How Much Is Too Little? There is a lot of debate about this issue, but more and more evidence is showing that you can not only eat too much salt, but too little as well. Another Useless Osteoporosis Drug In spite of the fact that more and more people are saying “no” to the useless drugs prescribed for osteoporosis …

                    1. thx, idk if you are talking about fruitarism containing only fruits or frugivore diet based on fruits and leafy greens and some nuts which seems to be much more balanced long term.

                      Pineapple is sensed to be very rich in iodine one of myfavorite fruit when gold color, yum, i eat half a big to a whole at a time et probably most fruits contains a little so it adds up, these nutrients dont seems to be a problem with the addition of greens, at worst, one brazil nut a day or even a week should be ok with the others foods.

                      It seems you are at risk of eating too little sodium if sweeting a lot and/or drinking too much(beyong thirst) which flush out blood sodium and/or eating too much fruits low in sodium and very rich in water like watermelon but melons are actually rich in sodium!
                      The real minimum daily need(not day to day obviously) for sodium without excessive sweating and drinking too much seems to be around 50-150mg only.

                      Here an interesting link about this topic:

                      https://nsm08.casimages.com/img/2014/09/22/14092201582117279112545495.jpg

                    2. Damn you are right, what Popper says about sodium based on some strange studies makes no sense in this video and what she says in comments below also, >2000mg of sodium is really a lot, i mean where are the salt shakers in the wild, we cant improve on nature, it dehydrate the body and cause many others problems, i’ll stick with what most others WFPB scientist says, the less salt added the better, SOS free(salt/sugar/oil free) Goldhammer add even gluten free.

                    3. I forgot to say we have salty taste receptors in our mouth to be able to taste natural sodium in whole foods and we can actually taste it if we stopped eating any added sodium for at least a month… there is no salt shakers in nature.

                    4. apparently humans have been seeking actual salt since before time was even being recorded, animals travel far for natural salt deposits also, someone said even apes hoard salt, so i dont know man, usually its greger saying we need this and that and this and that but salt is the one thing Pam says we need and Greger doesnt, Pam teaches people how to spot faulty studies for a living so i dont think her studies are wrong she has multiple videos on salt and multiple studies.. all over the internet it says too much salt is bad but so is not enough< and since most fruits have like 1mg sodioum you would be lucky to get enough sodium to avoid electrolyte imbalance issues like hyponatremia and according to science you would be at a huge risk for heart attack and stroke, p.s. when i say fruitarian i mean just fruit, otherwise what is the point of eating only fruit if you are willing to add in other toxic foods, if you are going to add some why not add as much as possible right?

                    5. Well, most fruits are low in sodium yep but leafy greens is the other most natural specy specific food for humanswith fruits and they conains much more sodium which is included in significant amount in a frugivore diet bonobo like, most of them surely arent toxic/harmful to us but beneficial and we cant improve on nature, edible mineral salt rock is very rare and you need to lick it because thats hard to chew and chewing a whole block is “burning the mouth when you are not used to eat it, disgusting, makes no sense, animals including humans are just very addict to it since long time ago, thats also why a cow can retardly lick it for hours and they they will be thirsty just like humans and not without reasons, thats another sign, there is no benefit in dehydratation, thats also why dry fasting makes no sense and is always harmful and dangerous, Robert Lockhart just died from it at 75 yrs old btw…he was an user of dry fasting.

                      https://www.youtube.com/watch?v=WZMX9BSVpwU

                    6. i know he did man, very disappointing, well apes do lick the rocks for salt and also dig holes in certain types of trees to get pith which has found to be really high in salt, they chew it to get the salty juice and then spit out the pith i just watched a video on it, also im not sure if you have ever grown leafy greens and tried eating them.. but i have.. and they taste toxic to me.. some mildly toxic, some really toxic, some made my teeth feel sticky.. and all didnt taste attractive, i could eat 1 leaf maybe, but i wouldnt be able to eat enough to make a meal out of it nor would i want to, besides. greens take up heavy metals and suspend them in there leaves as protection from animals who might eat them

    2. YR,

      I agree with you!

      I have gone through “try everything” phases and they seem so pretty.

      The concept that people with kidney issues can experience toxicity at half a fruit and die in 3 days is crazy.

      I look at the symptoms though and can think of times in my life that I had hiccups that lasted forever and when I had small seizures and I wonder if I had some back then.

      I didn’t buy any that I know of, but I did have those symptoms a long time ago.

      1. I looked up the hiccuping and they listed a long list of causes. Diabetes and Kidney problems are among the things listed.

        I felt better after looking at it.

        I haven’t had even one hiccup in a few years and it was a long time ago when I had it.

        I also had disturbed color vision back then with both eyes seeing different colors. That cleared up, too.

        I only had a few seizures and mostly when I hadn’t slept.

        I started looking things up and each of the things are common online.

        All of the symptoms are gone, but I am going to go to WebMD and type them all in and see what it says.

  1. i used to eat starfruit occasionally when i was living in southeast asia, but i have not had a single starfruit in 5 years.
    i dont have kidney decease and that means that the toxic compound is cleared up .

    but i am concerned about the oxalate toxicity, would the oxalate be cleared up from the kidneys eventually ?

    1. I don’t know about oxalate toxicity, but the neurotoxin, caramboxin, is cleared up by the kidneys (t=1:37 on the video).

      “The toxin itself, named caramboxin, is normally excreted by the kidneys; and so, is especially toxic to those with renal insufficiency—compromised kidney function—”

  2. Some fruits are more or less toxic apparently but often if unripe, theses fruits normally all have a bad and bitter taste, often extremly bitter, bitter and too acidic is a sign of toxicity by nature but sweet and salty(not too much) taste gives the green light when natural, good for us.

    I dont think a single good to delicious significantly toxic fruit does exist especially if ripe but unripe fruits are not good anyways and are often at least bitter and/or acidic again.

  3. FEEDBACK ON VIDEO FORMAT Mr Michael Greger is my wing man – I have watched ALL of his videos – many of them many times.
    High praise is merited for Dr Michael Greger and his team for their excellent work and mission.
    Thank you for what you have done and continue to do.
    Understand the following comments as truly constructive purposed feedback for getting the most out of the inputted work.
    This new presentation format creates a distraction effect – to have a person in screen serves no useful person and distracts from the science and journal articles and graphs and diagrams – better was the prior format – keep the screen filled with the science – go with the better format – the science filling the screen format. The voice carries our very good friend Dr Michael Greger – so we have it all with the prior format.
    OPTION 1 – Put the video together in BOTH formats – and allow people to buy the DVD’s / downloads in their preferred format.
    Plus or minus additionally – have a second replica website – resulting in two parallel websites

    One website carries the video format with the person in screen and the other website carries the videos without any person in screen – that is to say – the format where ALL the screen space and attention is being put on the science. Note: the comments in the comments section would be the same on both websites – comments are carried across from and to both websites in both direction.
    OPTION 2 – Go back to the prior video format – the “science filling the whole screen” format and have that as the only format – because it is the better for the science teaching conveying purposes.
    Feedback for your consideration
    Thank you

      1. Does it have to be one or the other? I would vote for “talking head” introductions and summaries, and voice-over (audio only) for the bulk of the discussion.

        1. Me too. I like to see The good doctor for introduction. However whatever is easier for Dr. Greger! Especially if the science is emphasized.

      2. I must agree… I like the older “all-science” format for these videos. (I get to enjoy watching you in interviews and live presentations.) To say I love what you do is an understatement — it’s changed my life and I’ve turned on well over 100 people to you and WFPB.

      3. Even though you are my favorite human Dr Greger, this new style is distracting and also think that newcomers might think a promo is hidden somewhere too. I prefer the old way of presenting the facts.

      4. I actually liked seeing you with this topic.

        More complicated topics, I find it too distracting.

        You compete with the topic and win.

        But when it was in the vlog long format, this format didn’t bother me at all.

        Mainly, there I was listening and following.

        Usually, I am trying to learn.

        It is nice to see your face now and then.

        But not on the hard topics.

        1. This format was refreshing in the fasting and cancer format.

          It was interesting how different it felt when I was not keeping up at all the first time you put a video up in this format versus the fasting and cancer vlog. This one, I felt you were spot on in your performance, but this format requires you to be “spot on” more than interviews and other Q & A’s.

          You are excellent at teaching and when I read the comment above where this format looks like a promotion of some sort, it might be that you are having to perform.

          You don’t do that when you are teaching long topics or doing Q&A’s.

          You nailed this one though.

          Good job.

          1. Honestly, when it was “cancer and fasting” on your birthday, listening to you live, this format felt special.

            When it was me trying to learn about the science that was over my head on this site, and I had to pause and rewind and start over a few times, it felt distracting.

            1. To throw in the wrinkle, I think for the vlog, if it had just been normal videos, it would have not felt as “live” and people might have been disappointed on that end.

              Did you get mostly good feedback from that? I loved this exact same format over there.

              1. For the vlogs, I was spending money to spend time with you and you being present mattered.

                If you just put up the normal videos for that, I might just wait for you to post them and not do the pay version.

                (That isn’t a threat. I probably will show up. It just is the “on the other hand” part of the equation.

      5. I agree a mix is good – quick intro then full page science. Many of us watch this stuff on our phones! Given the choice, one or the other, I prefer the old style.

      6. It’s far better than the time before when you went all graphics crazy a couple of years back, but really doesn’t add much to the content Doc. As another commenter noted, maybe just “talking Dr.” introduction/conclusion and leave the middle “all science”.

        It’s nice that the bumper has changed, but it’s long enough that I’ll always skip over it, the other one was so short that skipping over was as much hassle as it was beneficial.

      7. That would depend a lot on the charts being displayed, a visual often says that which words cannot. And then sometimes jokes or a facial expression might be what’s needed. Maybe a rule of thumb, charts and the speaker is overload, making charts useless.

        I could not help but wonder what percentage of people fit into the category of “avoid the fruit”. Is it 1% or 70% of the population; that felt like an important piece of information!

      8. As I’ve mentioned before, I find the videos with Dr. Greger on the screen to be very difficult to watch. I have a lot more difficulty assimilating the information with the distraction of Dr. Greger’s presence on the screen. I so enjoy the older format that emphasized the science, the nutrition facts, which is what this website is all about for me. I love being able to concentrate on reading the information on screen while listening to Dr. Greger’s voice. I think the idea of having Dr. Greger appear right at the start of the video only is an excellent one. I think that if the videos continue in this format, with Dr. Greger appearing in the video throughout, I will have to stop watching them, which I really don’t want to do!! Thank you, Carla

      9. I teach courses at both the graduate and undergraduate level and incorporated a number of your videos. In my opinion, the original format with the voice-over gives a bit more of an “academic” impression. Just my 2-cents.

        Thanks for all that you do and have a great Thanksgiving!

      10. I’m a much older guy with quite a history of trauma, so this may not apply to others. I agree with the video format comment that it is distracting. There seem to be too many visual aspects that move, shift and transit & your dynamic expressive visual presence takes up room spatially & competes with the other visual frames. I love your lectures & that format flows nicely. In this heavily multi-media format, I got confused, distracted & train of thought perception was interrupted enough that I had to go back several times to review what had just been presented. With the simpler primarily audio & visual text highlights & support charts/pics, I have no problems with following & retention. I’ve been watching your vids since the very beginning, before the website, buying the dvds directly from you! Thanks so much! ♡

      11. Viewing this video with Dr Greger in person did not interfere with my ability to comprehend the info. In fact, I thought that the Doc’s presence was a nice addition to his particular manner of speaking and spot on humor. To sum it all up, ‘the whole Greger is better than the sum of his parts’, so to speak. Both of his video formats are, in my humble opinion very effective. I recommend that Dr Greger should just make it easy on himself !!

      12. I agree completely with Andrew re “FEEDBACK ON VIDEO FORMAT”. The older style is far better as I also strongly agree with Andrew’s comment that the speaker’s presence is extremely distracting, resulting in less absorption of the subject matter.

        But his proposal for two websites to support the two styles is completely unsustainable financially. Totally unrealistic.

        Though I love your live presentations and talks Dr Greger. Thanks for the fantastic work you do!

      13. I like the audio only (not that I don’t like seeing your smiling face) because then I focus more on what you are highlighting in the literature and the diagrams. Love your work, Dr. Greger and that is what makes me a monthly supporter! :)

      14. As someone walking and chewing gum challenged, I am easily distracted and pay more attention to movements at the expense of the science visuals and even the spoken word. If this were entertainment, fine… but if it is informative, stick with the teaching aids. ‘-)

        1. I wonder if there is a walking and chewing gum study anywhere….

          As far as the “entertainment” concept, it is highly likely that the silent majority is entertainment oriented.

          They will never even come here so their vote will be in video views.

          1. When I looked at Dr Greger’s oatmeal video on Plant-Based London, there were 2 million views and 2 thousand comments.

            I looked at a few other videos and that ratio remained. I am sure different audiences would be different.

            The problem is he has to balance between the medical community and keeping their respect and keeping things simple and entertaining enough for mainstream audience and scientific enough for the science geeks.

            He is doing well at that process, but his trying to please us will never fully work because of how diverse the audience is.

            The more popular he becomes, generally, the more people will polarize into loving him and hating him and far too many people won’t remember to appreciate him.

            But if you look at polarizing personalities like Dr McDougall and Dr Fuhrman it becomes “He saved my life” versus “He is such a….” whatever negative focus thing there is to focus on.

            I can’t think of any.

            1. The thing about putting his face on it, in some ways it will make him more of an idol for those who idolize and it will make him seem more self-centered for those who want him to step out of the way and let the science speak.

              The same intro that seems welcoming over in the conferences will seem self-promoting here.

              It will take some figuring out to keep a balance.

              The problem is the more effective he is, suddenly a portion of the audience will want to throw pies at him and a portion of the audience males and females will want to sleep with him and use him to help them make money.

              I think I just entered an Eagles song.

              1. The distance between going up and falling down and having a Veg Source video is pretty small.

                I can’t imagine having fame. Influence becomes influenza in my cell phones word replacement process.

              2. “……suddenly a portion of the audience will want to throw pies at him and a portion of the audience males and females will want to sleep with him”
                – – – –

                Mmmmmm, I love me any kind of fruit pie. They can throw them my way!

                Dr. G., do you have trouble fighting off fans who lunge at you and attempt to crawl into the sack with you? If so, maybe you should carry a police whistle around with you. ;-)

          2. As far as the “entertainment” concept, it is highly likely that the silent majority is entertainment oriented.

            They will never even come here so their vote will be in video views.
            ———————————————————————————————–
            Have to disagree with your last statement. That is, I think people will continue to watch the videos no matter which format is chosen, if you can believe the comments.

            Even I, who am on record as favoring the old style, will continue to “listen” but will scroll down so I don’t see the distracting gestures etc.

      15. Like many other previous commenters, I prefer the older “all-science” format for these videos. The personal touch is great in interviews and live presentations, but I find it too distracting on the regular weekly videos.

        Maybe a compromise would be a very short appearance at the beginning to introduce the topic and a short appearance at the end to summarize the findings, and the other 90% the old style with the research papers, charts and graphs.

      16. To me, the science is leading and the most useful video format. It is more entertaining in this format, but entertainment is not my leading concern when using NF.

        Also, I believe there is a lot of distraction on the website surrounding the video’s:

        * The video fills the width, even when not enough height is available, so need to resize/fullsize every time
        * Overlays with “social” networks cover video’s
        * Popups to subscribe, join, unite come up very often

        These are only comments on the format, not on the content, which I think is excellent and highly interesting.

      17. Dr. Greger, I deeply appreciate your videos, as well as your books. I, personally, am happy with either format. Thank you so much for all you do.

      18. The initial personal appearance is great but the mixing of personal image and the written studies is very busy. I prefer the old format when the studies are shown.

        Thanks for the request for feedback.

      19. I guess my preference is for the older charts and graphs style. But I eagerly watch your conference videos. Please continue to publish those.

      20. audio only for me. You popping up once in a while is fine and a bit entertaining. Thanks for all the work you do. Have referred hundreds to your site.

      21. Dr. Greger as handsome as you are it is really distracting from the science for you to be on the screen. I told A friend of mine who is a follower of another doctor who preached another diet that it wasn’t about you it was about the science. It helped when you weren’t on the screen.

      22. I very much liked seeing you and for me….
        it made it so much easier to follow your words and wisdom and advice.
        I know how busy you are so imagine whatever is easier for you has to be it.
        Thank you so much for all you do for us.

      23. Whatever is easiest for you Doc! Personally I believe the FEWER “Bells & Whistles”, the greater the “comprehension”, however we would need to “put it to the test” to see if it is true for the majority :-)

        1. Not sure, OZ… too fews “bells and whistles” can be dry and boring and lead to drifting off. Take a full on pubmed article… interesting as the content may be, the way it’s presented I actually hypothesize it increase melatonin production, thankfully not in Dr. Greger!

      24. I like all science. (No offence, Dr. Greger, you’re a pleasant looking guy, and we all love you, and owe you a huge debt.) NF is first and foremost a wondrous educative tool. I pause the videos frequently to take a longer look at the studies, and absorb all the data you’re presenting.

        That said, it is very nice to say the face and smile once in a while.

      25. Dr. Greger, I love your videos and I love both styles. I actually think it’s cool to see you talking on screen–really engaging and it kind of brings the video to life. I don’t see it as a distraction at all, your videos are as straightforward as ever. Part of why I’ve always loved your videos so much was because while I love the immensely useful and interesting science, I loved the way you presented the science in a lively way with all the great visual content to help give a better understanding. Seeing you pop on in the videos is a cool little surprise and something new and fun and makes it cool and personable. But if it’s easier not to do it that way, I love the videos either way. And to me, I don’t really care–be random and do it differently as much as you want–all I care about is the great info and the way you present it whether on screen or off.

      26. I agree with Andrew – All science please.

        But I do want to thank you for a fantastic work you do – the information you provide is, I believe, helping enormous number of people – greatly appreciated .

      27. Hi Dr. Gregor,
        Six months after reading How Not to Die and changing my diet to comply with the whole-food, planted-based diet I had serum lab work done and had the best blood sugar, triglycerides, and lipids levels in my life.
        So for the next three years I watched your videos most mornings for the inspiration to stay on plan. I found them soothing and informative.
        But now the new format is so off putting for me I can barely make myself watch them. Before the videos were about the science. Now they highlight you, and as much as I love and appreciate you, your speaking style overrides the message. In essence the videos messages were ‘here’s the science.’
        Now the message is ‘Here’s Dr Greger with some science’
        I have fallen off my diet and literally regained ten of the thirty seven pounds I lost. I used to forward your videos to friends and clients and now I just can’t feel right sending them.
        Please put the science first and reduce the risk the messenger will kill the message!

      28. I prefer the older style with the studies & diagrams,but love that you finally took out the whooshing sound at the beginning! I don’t think you should make 2 versions,do you even have time to do that?

    1. Thanks for the warning on star fruit. It seems like this food should be avoided.
      ——————————————————————————————————–
      Or even banned and made to go extinct!

      1. “Made to go extinct?” Why?

        I would never eat poison ivy berries — but birds do, and thrive on them, presumably as part of a healthy diet. As do other critters, no doubt. Which why I see some poison ivy pop-ups in my backyard. And many animals take shelter in the leaves; some also eat the leaves.

        “there are other mammals, birds, reptiles, and amphibians that can eat the plant and its berries, and also use the plant as shelter. A variety of insects feed on the flowers of poison ivy too – from beetles to flies, bees and butterflies…
        Many birds including Northern flickers, Bobwhite quail, Eastern phoebes, Cedar waxwings, Woodpeckers, Tufted titmouses, American robins, and others eat these berries in the fall and winter.

        White-tailed deer, raccoons, and black bear are able to browse on this plant as well. They will eat the leaves, fruit, and even the stems. Poison ivy as a ground cover or shrub can provide cover for small animals and as a vine, it can act as a path to climb up and down trees for small mammals and lizards.“. http://www.tarawildlife.com/wildlife-value-poison-ivy/

        And not all people are allergic to poison ivy.

        My point being that even if I can’t eat the berries or safely touch the leaves, stems, or roots, other people don’t have this problem, and other animals find poison ivy just fine. So, should I want to ban it?

        1. D R J,

          Excellent defense of poison ivy… you’ve convinced me. Let’s keep it.

          But we are talking star fruit and I don’t think any of your positive points for keeping poison ivy translate to star fruit?

          1. Lonie,

            OK, here it is: My point is, we probably don’t know what animals, fungi, bacteria, or other plants benefit from star fruit. We don’t know what or whom it benefits, or might benefit, that might ultimately benefit us. We don’t have to eat the fruit if it’s not safe for us. So why would you want to make it go extinct?

            We are already making a lot of species go extinct. Probably too many.

            1. We don’t have to eat the fruit if it’s not safe for us. So why would you want to make it go extinct?
              ——————————————————————————————————————-
              From what I’ve read, the star fruit tastes good (when ripe.) That makes it, what is called in the insurance business that is, an attractive nuisance. It’s like having a pool in your back yard but no latch on the gate to keep someone (children especially) from falling in and drowning.

              And it seems I’m not the only one thinking total eradication as this was posted well down the list by Carolina:

              I am Brazilian and I used to enjoy start fruit. It is sweet and refreshing. We ,made juice and drank several glasses in the course of a few hours. Never heard of anybody having an adverse reaction; maybe everyone had healthy kidneys then. It is true nowadays there are warnings against the consumption of start fruit and there was mayor who wanted to pass a law to eradicate the tree from his municipality after his mother died of kidney failure.

              1. I suspect thats mainly a problem with unripe fruits or not completely ripe star fruit, many fruit have bitter toxic compound when unripe and not when ripe.

                1. I suspect thats mainly a problem with unripe fruits or not completely ripe star fruit…
                  ——————————————————————————————-
                  ITBT (If That Be True) then D R Greger should have pointed that out in his presentation.

                  1. Lonie,

                    I looked through the literature and none of the studies said “unripe” or “not completely ripe”

                    The studies discussed the kidney function of the people eating it.

                    There was a high mortality with people who had kidney problems.

                    ” the mortality of patients among reported cases with chronic renal insufficiency and end-stage renal disease undergoing dialysis were 36% and 27%, respectively. With the inclusion of patients reported to have NRF, the overall mortality was 24%.” (NRF means that they added in the people with normally functioning kidneys and the mortality rate changed to 24% – still way too high.)

                    1. Thanks Deb for doing the research… I think extinction should definitely be on the table as I’ve heard no compelling evidence to the contrary other than extinction equals bad.

                      To me, if an organism is neither predator nor life-dependent prey, the ecosystem will hardly notice.

                      Case in point? Ireland has been fine even though St. Patrick got rid of all the snakes. ‘-)

            2. Dr. J, I completely agree with you but only because you’re 100% right. It is unwise and moreover, moronic, to want to make a native plant life go extinct because the fruit probably shouldn’t be consumed by humans. And to suggest such a silly thing–a crusade made in pure ignorance–is a good example of the shortcomings of man’s thought process and one of the reasons mankind tends to screw things up so badly. It’s just plain stupid.

              1. It is UNWISE and moreover, MORONIC, to want to make a native plant life go extinct because the fruit probably shouldn’t be consumed by humans. And to suggest such a SILLY thing–a crusade made in pure IGNORANCE–is a good example of the SHORTCOMINGS of man’s thought process and one of the reasons mankind tends to screw things up so badly. It’s just plain STUPID.
                ——————————————————————————————————————————————–
                I agree with you… that Mayor in Brasil who wanted to eradicate all star fruit trees because he lost his mother to kidney failure was acting out of grief rather than reasoned thinking.

                “It is true nowadays there are warnings against the consumption of start fruit and there was mayor who wanted to pass a law to eradicate the tree from his municipality after his mother died of kidney failure.”

                On the other hand, how many people are walking around with neuron damage or with kidney damage from eating the star fruit, that very well may lead to dialysis later in life? The mayor mayor’s idea may have resulted from a knee jerk reaction but that doesn’t make it wrong.

                But your stance reminds me of an island in the Northeast U.S. (can’t remember where exactly) who were given the opportunity of a CRSPR gene drive to eradicate Lyme disease from the island. The island inhabitants chose not to have a Lyme free ecosystem… I wonder how many more cases of the disease there have been from a debilitating disease caused by a tick… that has no required place in the ecosystem.

                Extinctions have been going on since biology on earth began. Most people just recognize it as “change.”

                1. Lonie,

                  No, the knee jerk reaction isn’t what made it wrong, the fact that it is an uneducated and irresponsible act to the ecosystem is what makes it wrong.

                  Banning a tree is the most ridiculous thing. Have they banned noni fruit trees or bushes or whatever the hell they grow on? Or what about the elderberry plant? Those are toxic when raw from my understanding. Not to mention the plethora of other poisonous fruit-bearing plants. Let’s make them all go extinct because humans are too stupid to be able to learn that something may be dangerous to consume is the message here? Then eventually, as we start using that sad replacement of logic in our ways of doing all things—which sounds like a ‘solution’ a 5 y/o might conclude–we’ll make ourselves go extinct from destroying the planet. Sounds like a plan.

                  Lonie, how do you know what has no required place in the ecosystem? That was rhetoric, because you don’t. The ecosystem lives on the most complex and brilliant science. Introducing for example, genetically modified insects to change this or that has potential repercussions we couldn’t even begin to understand. I’m sure the people made their decision based on weighing it all out.

                  Your spiel on extinction is a sad way to try to argue a bunch of morons getting angry at trees. Extinction throughout the millennia has happened gradually and naturally not because Joe decided that he didn’t like white roses so they all must be torn from the earth this year.

                  1. Banning a tree is the most ridiculous thing. Have they banned noni fruit trees or bushes or whatever the hell they grow on? Or what about the elderberry plant? Those are toxic when raw from my understanding. Not to mention the plethora of other poisonous fruit-bearing plants.
                    ——————————————————————————————————————————————————————————
                    IIRC, noni fruit trees or bushes or whatever the hell they grow on… are beneficial as noni juice is an established health brand. Cashews are also poisonous until properly prepared, but I love those things. Star fruit, if we can believe the evidence base D R Greger has posted here, are life-threatening and with no other redeeming qualities other than they taste good and are refreshing.

                    As I pointed out in another post, either in this comments section or another one, very intelligent people are knowledgeable in some fields but uneducated in others. I feel like I’m well read but I was unaware of Star fruit’s dangerous side. If, like Carolina said, her neighbor used to give her bags of the stuff from the tree in his yard… if that happened to me I very well might have over-indulged in the “treat” and ended up on dialysis or dumbing-down due to neuron damage. Not knowing isn’t the same as stupid.

                    S, you had it right in your first sentence above, but you’ve twisted the meaning in the second sentence. Back during the ’50s the govt. chose to eradicate the screworm fly to stop the loss of animals (young calves mostly) to the infestation. On our farm, we would castrate the young bull calves and cover the wound with smear… a black thick coating to keep the flies out of the wound. Still, the smear didn’t always work and a calf would contract the worms the flies laid as eggs. Then we would have to doctor the calf with Peerless Screworm medicine TM. But if the calf were in the pasture and went unnoticed, it would die.

                    So the govt. created the Screworm Eradication Program and released sterile flys at regular intervals until finally the screworm fly was eradicated.

                    As far as I can tell, the only downside to that eradication was the loss of business for the smear product and the Peerless Screworm medicine product.

                    1. “Cashews are also poisonous until properly prepared”

                      What the hell are you talking about? Cashews are safe eaten raw. I get them unpasteurized and hand cracked (when on sale) so as to be thoroughly raw… best cashews I’ve ever had. And I make sauces out of them, not just having a few here and there.

                      “noni fruit trees or bushes or whatever the hell they grow on… are beneficial as noni juice is an established health brand.”

                      A plant being an established brand for some commercial interest does not deem a plant’s value in the ecosystem. Also, Dr. Greger warns about that established brand as noni juice has harmed a lot of people.

                      “[star fruit] are life-threatening and with no other redeeming qualities other than they taste good and are refreshing.”

                      A fruit from a plant doesn’t need “redeeming qualities,” just don’t eat the damn fruit if it isn’t healthy for you. The plant is a part of an entire ecosystem. And as Dr. J pointed out, we have no idea what kind of animals eat the fruit.

                      “I call bullshit on that… ’nuff said.”

                      That actually is not enough said at all, more like there was nothing you could say to the practical comment in regard to the illogical and irresponsible suggested way of doing things. And indeed, there was nothing you could say.

                      In regard to your story about the demonic torture you practiced, I’m just disgusted but unsurprised. I know all this stuff goes on, but it is pure evil and that is all I will say but not all that needs to be said.

                      Evil people torturing animals goes against the ecosystem, so your story about flies holds no relevance. Always caused by man. Example, sheep bred to have a special type of wool have folds in their skin which happened through humans breeding them that way, so it made it a perfect breeding ground for flies to settle in and harm the animals. The solution was to put the little baby lambs and full grown sheep on rotating wracks and use a hedge clipper-like device to routinely hack off chunks of their flesh with no anesthesia as it always goes, later of course the flies would infect their wounds and so it goes. To others readers, don’t buy wool.

                      “(Apoligies for bringing up the castration of bull calves into your consciousness… hoping your heart isn’t experiencing too much blood loss.)”

                      I’m not going to pretend that’s an actual apology with the underhanded remark at the end. But I’m fine with it; I don’t need or want an apology. I have seen and I know what goes on to the animals more than even you, a holocaust. And it must be very convenient for you to live so comfortably in your own belief system, but it isn’t my heart or health (as you’ve suggested in the past) that you should pretend to worry about, it’s your soul.

                      I don’t talk about this kind of stuff here, but when someone happens to bring up cutting off the genitals of enslaved, tortured babies, I find it unavoidable.

                      “The resin within the shells of the fruit is used as an insecticide and in the production of plastics; it also is important in traditional medicines. The cashew apple is used locally in beverages, jams, and jellies, though most cultivation is directed toward production of the valuable seed crop. Parts of the cashew must be handled with care by susceptible individuals because it is related to poison ivy and poison sumac and can cause an allergic reaction in some people.

                      The true fruit has two walls, or shells. The outer shell is smooth, thin, and somewhat elastic and is olive green until maturity, when it becomes pale brown. The inner shell is harder and must be cracked like the shells of nuts to obtain the edible seed inside. A brown oily resin is produced between the two shells and can blister human skin.

                      Dad’s the one who did the cutting but he made sure the knife was sharp and he made a quick cut so the bull calf wouldn’t feel it so much… he also “worked the calves” when the signs were right (that is, the blood was flowing away from the area so the calf wouldn’t bleed so much.) But evil? No, Dad was a stern man but not at all evil. As I’ve gotten older I’ve grown to recognize he was a better man than me.

                      Hey! Wait a minute!… Aren’t you the one who posted you have the cat friends at your place neutered?!!!

                      ‘-)’-)’-)

                    4. Lonie, I’m thinking S has a major crush on you. Youth has such passion! :-)
                      —————————————————————————————————-
                      I think it is more like she wants to crush me ‘-)

                      Seriously, I’m not really qualified to analyze, but it seems to me she is picking fights all over the comments section… maybe to stimulate her intellect or possibly to release her anger or disappointment in someone in her personal life.

                      Or maybe none of the above. ‘-)

                    5. “…..but it seems to me she is picking fights all over the comments section…”
                      – – – – –

                      I thought I was the only one who always noticed that. Yes, possibly a huge disappointment of some kind in her personal life. But, really, is there any need to attack a poster as being “insane” etc.? With some accusations In all caps yet? :-/

                      I think she (more than) once said she has obsessive compulsion issues, or ADHD or something. ????

                    6. But, really, is there any need to attack a poster as being “insane” etc.? With some accusations In all caps yet? :-/
                      ——————————————————————————————————————-
                      To be fair to S, I think you are remembering me changing one of her posts to all caps in order to point out the charged words she was using, to her.

                      And as a debater, she does go for the jugular with words like insane and moronic etc. (Used to do this as well, but learned that humour is a lot less confrontational and more likely to score debate points. ‘-)

                      Side note: YR, isn’t it great we can have this secret discussion about S behind her back? ‘-)

                    7. “To be fair to S, I think you are remembering me changing one of her posts to all caps in order to point out the charged words she was using, to her.”
                      – – – –

                      Yes, yes, I do remember that. But, she caps a lot of her words in general. I can see why, in most cases; there’s no emphasis button at this ‘ere-place. It would help if there were.

                      Uh-huh, “behind her back.” Hopefully she’s wandered on to other pastures by now. Otherwise, I ‘spect my head will roll. :-)

                    8. “Dad’s the one who did the cutting but he made sure the knife was sharp and he made a quick cut so the bull calf wouldn’t feel it so much…”

                      Oh, well then my apologies, he wasn’t being evil at all… Please recognize the sarcasm.
                      Why don’t you sharpen a knife, and try it out on yourself, then and only then can you have any opinion on how much the baby boys felt it.

                      “But evil? No, Dad was a stern man but not at all evil. As I’ve gotten older I’ve grown to recognize he was a better man than me.”

                      Same goes. You were treated as your father’s son, the babies and whoever else your family “farmed” were treated as the slaves and tortured victims they were. Therefore, you proclaiming your dad’s innocence means absolutely nothing.

                      “Hey! Wait a minute!… Aren’t you the one who posted you have the cat friends at your place neutered?!!!”

                      Obviously not taking this comment any more serious than you are, sadly I’ve been in the world long enough to know people are that ignorant about the most apparent things, so it needs pointed out that neutering/spaying under medical care, anesthesia, and post-op care is comparable to having your child undergo a surgery they need, and not comparable to torturing children for your personal gain… That was today’s lesson, next week kids, we’ll start learning addition.

                      I am done on this and will not be revisiting this conversation. I only just briefly read the childish, what could actually be called bullying by YR… I guess mercury’s in retrograde again, and you. You two are the children on this site, aren’t you. That will be the last comment I make after having read just the very begging, God knows how long you two went on, I’m sorry you don’t have better things to do, I really am.

                    9. Why don’t you sharpen a knife, and try it out on yourself, then and only then can you have any opinion on how much the baby boys felt it.

                      O.K., I took you up on your dare and cut ’em off. Drank a bottle of whiskey first and to tell you the truth, I hardly felt a thing.

                      But the whiskey wore off and I realized what I had done… so I’m writing this from the emergency room and a D R is sewing them back on.

                      Please don’t challenge me with any of your insane ideas going forward! ‘-(

                    10. YR,

                      you really are a nasty person aren’t you…

                      I have seen you make cruel personal comments to Dr. Greger for lack of hobby or something, I have seen you fill this website up with ridiculous dribble that has nothing to do with anything but you for some reason liking to spend your time here without it being for the science of it, I have seen you make mean and personal digs at one of the most scientific and intelligent posters on this website for no reason at all apart from finding some childish amusement of it.
                      Yes, this is a science-based website, and I have not been the only frustrated one when every so often coming across a commenter relentlessly spreading false and dangerous misinformation based on zero evidence–calling these people out is not “picking fights.” In an ironic twist, it is what you continuously do on this site that is obviously intentional to “pick fights,” again, for some childish form of entertainment.

                      You’re right that I have OCD, a lot of people go through a lot of things… I have no idea what issues you’ve had to struggle with, but I sure as hell would never be such a truly gross human being to for no reason, attempt to use that as a personal dig against you as I went on to slander you on some comments board. You just make yourself look bad and show yourself for who you are when you try to hurt people that way.

                      I do suggest you get back into the movie extra business or pick SOME kind of hobby (btw, where no italicize is available, caps are used to emphasize a word). Maybe you’ll start laying off a little here, if you do, and when you do come and comment, it won’t be to just loiter and make personal digs at people.

                      You say youth has passion, I thought age was supposed to have wisdom. These things aren’t rules, though, are they.

                    11. S,

                      There there now girl…..take a deep breath; let it out slowly. Repeat. But it does feel good to “tell it like I perceive it,”
                      doesn’t it! :-)

                      I’ve heard that the so-called faults we see in others are those we see in ourselves. I wonder if that’s true.

  4. Never see these around here in backwoods America. But I might have found some at the International market-down in the big city next door, and I do like trying new stuff. I’ll pass on this one.

  5. People eat these in my hometown all the time when in season. They make juice, jams, or eat it raw. They’re still alive and don’t suffer from any diseases.

  6. This video highlights the point that all plants exist on a spectrum of friendliness to humans. Even those of us who are 100% plant-based should guard against naivete, i.e., “plant=healthy”.

    Some of the most beneficial phytochemicals originally serve a defensive role in the plant. Think of sulforaphane.

    Some plants are primarily toxic with little or no redeeming value (I would put star-fruit in this catagory),
    some have some toxicity, but their health-promoting attributes outweigh their poisonous ones (think of flax seed and cyanide),
    some are healthy as hormetic stressors in our bodies,
    and some are apparently wholy benign.

  7. What about cherimoya ie: graviola, custard apple, guanoabana, soursop, or brazilian paw paw? Why does it have so many different names? It makes me sick to my stomach when I take the pill, juice or fruit, why? It is supposed to kill cancer cells.

    1. How about 5 seconds of Dr. Greger? You get the personal touch, then can focus on the academics. I agree with Tt: How about a video on North America’s largest native fruit: pawpaws?
      John S

  8. Thank you Dr. Greger. I love star fruit and occasionally eat them (may be in good quantity since I love them so much)
    Thank u for the warning. Appreciate your work and your goals.

  9. Hi Dr. G! I love everything you do and will watch, listen and read no matter what the format. Your engaging presentation and tangy sense of humor always makes any topic and all the science more memorable and fun to learn. I think the ideas suggested above where you are visually presenting the intro and conclusion, with just voice over in the middle explaining the science would be a good best-of-both-worlds approach. Thank you so much for all you do! Add me to the count as another person whose life you have changed!!

    1. “I think the ideas suggested above where you are visually presenting the intro and conclusion, with just voice over in the middle explaining the science would be a good best-of-both-worlds approach.”

      That is a good idea. I do love the scientific charts and all that.

  10. After watching this video, I thought: What is star fruit? And who would eat it, and why?

    So I looked, and the first article that popped up: “Carambola Fruit: Here’s Why You Should Add This Exotic Fruit To Your Diet!
    Carambola or star fruit is one of the most sought after fruits due to its nutrient density and antioxidant levels. This exotic fruit is definitely one of the best fruits that promote health!”. https://food.ndtv.com/health/carambola-fruit-heres-why-you-should-add-this-exotic-fruit-to-your-diet-1833845

    There are several other articles along the same line, including on Healthline and Mercola (both of which I try not to visit). However, the National Kidney Foundation article title: “Why you should avoid eating star fruit.” 5th on the list of search results.

  11. As a person with chronic kidney disease (although it is improving greatly since I went WFPB), I wonder why this is the first I have heard of this. Of course, I live in Vermont where these things don’t exactly grow on trees. Thank you, Dr. G, for the heads up.

    On the video format, I am generally neutral, although it is nice to see the good doctor’s face in these videos. Therefore, count me in as a vote for in-person intros and audio-only science.

  12. I’m a “read transcript” devote; it’s much quicker for me to get through Dr. G’s message. It’s fun to see his smiley fast-talking face once in a while, but I think he should trend himself up with a bright t-shirt as suggested by another poster. And/or maybe wear a colorful beanie propeller cap. :-D You know, think outside the box. (Of course, then there would be a whole new slew of objections from the bleachers.)

    Last winter I left a warm brown (and expensive) mitten on the bus, but I hated to throw away its lonely mate. This morning when I took the bus to go shopping I wore the mitten along with one of a lighter shade of brown. It was obvious they didn’t know each other but they were both soooo warm! (I think mittens keep your hands warmer than gloves; it would probably be hard to drive a car with them though.)

  13. I was astonished that consuming so few starfruit could be so damaging. Doing without is no sacrifice under such conditions!
    Surprising to see that a heavy percentage of the comments are about format rather than content, even given that the content is pretty straightforward

  14. I had never heard of star fruit…..until now. So I did a search and found a nice article from your old friend, Dr. Mercola, on How to Eat Star Fruit. To his credit he did suggest it be eaten in moderation……because it contains fructose.

  15. I am Brazilian and I used to enjoy start fruit. It is sweet and refreshing. We ,made juice and drank several glasses in the course of a few hours. Never heard of anybody having an adverse reaction; maybe everyone had healthy kidneys then. It is true nowadays there are warnings against the consumption of start fruit and there was mayor who wanted to pass a law to eradicate the tree from his municipality after his mother died of kidney failure.

    A friend of mine has a beautiful start fruit tree and the variety grows huge and sweet fruit. He gives bags of it; so many I do not know what to do with them. Now that I have learned about the neurotoxin, I do not think I can eat them any longer. A real shame.

    1. Hi Carolina, thanks for your comments. This is an important information about star fruit and limiting consumption that Dr Greger has made especially for people with kidney issues. You mentioned you used to enjoy glasses of juices of it that made me wonder if the new varieties that are now available is a different hybrid of the old fruits? Anyhow, keep caution and advice your friends too of this information. Thank you.

  16. You look great Dr G! With that said, Time is precious. I recommend you just do the audio for these videos. Seeing you speak, as well as Live Q&A on Facebook and YouTube is plenty. Of course, you can do whatever feels right to you; you’re the leader. Happy Holidays!

      1. S,

        The Webinar, that is how I experienced it.

        But the graphs and charts are lost on me in this format.

        If the other version is easier, maybe just punch things up for the Webinars. Those videos will still come here and annoy everybody.

        Maybe the first video of the Webinar series or first and last with Dr Greger and the detail-oriented videos in the other format.

        The Webinar needs to be elevated but that can be off-video time.

        The Q&A was excellent this past time, but that part could be hit or miss.

        It is a pay format and was fun and I stayed in listening mode rather than learning mode.

        This format is frustrating in learning mode.

        1. Deb, for me listening is also learning, but apparently some people need to charts and such. However, I do really love the charts because they give a great understanding of things. I definitely wouldn’t want that style to go out the window. I liked what other people suggested, do the intro and outro with Dr. Greger on screen and keep all the cool science stuff in the duration of the video. If I had to choose one over the other, I would choose the charts and graphs and articles for sure.

  17. Definitely will not eat this fruit. The point of fruit is that it’s amazing for you, not that it can be harmful. Seems starfruit just isn’t one we’re meant to be eating. It’s a shame, it’s so pretty!!!! I normally complain that it’s so hard to find a variety of organic TROPICAL fresh fruit available, but in the case of starfruit it’s a good things because it’s probably the only reason I never tried it.

  18. I tried starfruit a couple of years ago; it was okay but quite expensive. I saw it at the grocery store last week and thought about buying some but it was $5.99 a pound. Thanks Dr. Greger, I won’t think about wasting my money on this fruit in the future.

  19. Good day!
    we are engaged in muscle treatment (trigger points)
    and faced with cases such as muscle fibrosis.
    we treat him with a hard deep massage.

    I tell clients to include more plant foods. But it’s so hard to convince them.

    We encounter patients with very large muscle fibrosis. Are there any ways to improve treatment? What plant foods are more likely to help treat muscle fibrosis?

    1. Rain,

      I don’t know if anybody medical will answer.

      When I looked at PubMed they talked about muscular insulin resistance.

      Insulin resistance is related to fat in my mind. I don’t know if that is the same for muscles, but Game Changers documentary came to mind and how the Keto diet hurt muscles.

      Yes, I know nothing at all and this isn’t one of the subjects I dealt with in my life, but maybe my saying it will lead someone else to think of something. Either way your posting it puts it on Dr Greger’s potential topic list.

      Maybe a few months from now it will show up.

      Game Changers can be streamed online.

  20. Okay moderators, av integrin inhibitor was mentioned and antiangeogenesis was mentioned with integrin as a concept.

    Leucine was another topic and, yes, I don’t understand any of it, but I know that there are angiogenesis and anti-angiogenesis diets and someone other than me might understand things.

  21. I’m confused by the low volumes of starfruits required to produce symptoms. Living in Miami, many people – myself included – have starfruit trees in our yard and will eat them at a hefty clip (2-3 a day for a month, more once the tree grows up) during the season. If this is to be believed, how are people with trees in their yards not dropping like flies all over Miami or SE Asia? Is it because we allow the fruits to FULLY ripen (i.e. fall off) the tree before eating? Is it because I’m just lucky to have healthy kidneys (for now)? Do we know if the measured effects on the fruits were tree-ripened or chemically ripened ones? I must say mine taste way different, more sweet, than any I’ve ever had from a store. Is there a way to measure oxalate levels in my tree’s fruit at home?

    Or should I just chop the tree down? :(

  22. Thank you so much!!! I love starfruit but this’ll save me some money and better still my health! <3 Thank you for helping me yet again. It's so much easier to do better with information you trust rather than wondering if you're missing out. There are so many beneficial tasty foods.

  23. Do you mean unripe starfruit dr Greger? Unripe ackee will kill you… yet its jamaicas favourite fruit.. I feel like its important to mention ripeness if you are going to mention it at all as I imagine a ripe picked sweet starfruit wouldnt have these oxalates and issues because its ready to be eaten and have its seeds spread like any other fruit.. wouldnt want to put any starfruit growers out of business or stop a winter bearing fruit from being grown and eaten over faulty information now would we?

    1. Hey YR, I suppose it is easy to get by, healthily, without eating green bananas… but green ones are the only kind I will buy. I usually buy them in a big bunch and by the time I get to the end of the bunch they still have over tones of the green taste, but probably still have the capability of producing Butyrate in the intestine.

      I have to admit the early ones that are really green do not peel easily and do leave a heavy feeling in the stomach. But as days pass, they become easier and easier to peel and eat.

      But a very ripe, spotted peel banana is (sic) unappeeling to me. ‘-)

      1. I agree with you about an overripe banana, Lonie. Blech! Way too gag-worthy. That’s why, as soon as they look somewhat spotted with brown, I immediately peel the lil’ suckers and put ’em in a freezer bag. From there they go into the refrigerator freezer.

        I luuuuv partially defrosted banana chunks on top of my hot cereal in the morning — just the perfect amount of sweetness. Only 1/4 teas. of honey or molasses is necessary, if that. The bananas, blueberries, some sliced almonds or walnuts, sprinkle of cinnamon and ginger, a tiny bit of misu — maybe some hemp milk — and it’s “dessert time!!”! Definitely one of my favorite meals.

        And I add more to this breakfast agenda, but I’ll stop while I’m ahead. Don’t wanna sound like a pig, doncha know. :-)

  24. So in Asia, we always cut the ridges off the fruit before eating it. My understanding is the toxins are concentrated in the ridges. I’d like to know how the starfruit were prepared in these studies?

  25. Hello everybody,

    I would also prefer less work for Dr. Greger and more focus on the science for the viewer with the older papers and charts only format. I’m writing a book and Nutritionfacts is an important research source for it so that’s why I was insisting on it for some time now. Writing a book is so much work! I’ve been going at it for about 3-4 yeard now.

    Anyway. Thanks for asking Dr. G. I think that’s pretty cool. See you all… later.
