Doctor's Note

I previously addressed how we discovered the endocrine disruptor phenomenon in Alkylphenol Endocrine Disruptors and Allergies, as well as where they’re found (Dietary Sources of Alkylphenol Endocrine Disruptors).

For more on sustaining male virility, see Male Fertility and Diet, The Role of Diet in Declining Sperm Counts, and Dairy Estrogen and Male Fertility.

I’ve talked about the role a plastics chemical may play in male sexual functioning (BPA Plastic and Male Sexual Dysfunction), but It’s not just toxins, it’s the total diet (Survival of the Firmest: Erectile Dysfunction and Death)–and not only in men (Cholesterol and Female Sexual Dysfunction).

    Diatomaceous earth and/or boron (DE has boron, but adding more never hurt) helps tremendously with both removing pollutants as well, helping to balance hormones… including increasing testosterone in men.

    • Nigel Oswyn

      That’s the same stuff found in clumping cat litter. Uhh, ….no. I’ll stick with actual food like garlic.

      • Justin

        shouldn’t knock it before you read about it. google: ‘diatomaceous earth health benefits’ also, check out the paper/study that pops up when you search ‘diatomaceous earth cholesterol’ … or don’t. but, to dismiss something without at least giving it a brief once-over is a classic example of ignorance at its finest

        • Justin, tossing out the word ignorance in the direction of a posting member of NF is unnecessarily rude, especially on a site most of us visit to learn something. Nigel’s preference was not expressed unkindly. Couldn’t you have found a more effective way to encourage him to read your reference?

          • Justin

            I believe you may be projecting in how you’re interpreting how that was written. The Merriam-Webster dictionary defines ignorance as: ‘a lack of knowledge, understanding, or education. the state of being ignorant’.

            My sentiment was conveyed initially in suggesting ways to find information relating to diatomaceous earth, its health benefits, and its health benefits relating to something specific (cholesterol in this case). … with my simply stating a more ‘matter-of-fact’ statement that still seemingly applies in rereading it that ‘knocking it before he read about it’ is, in fact, ignorant… or showing ‘a lack of knowledge, understanding, or education.’

            Technically this is correct. You may need to read it like a robot was saying it to get intent. … but, there was actually just as much if not *more* ‘attitude’ and ‘expressed unkind dismissal’ in the ‘Uhh,…no, I’ll stick with actual food like garlic’ line than there was in mine. It also sets the stage for a negative association of feline feces and diatomaceous earth… despite ‘countless’ out there swearing by the stuff and having achieved amazing results from using it. …as nearly a half-dozen facebook groups dedicated to the substance would reinforce.

            Again, the negativity is in both your projected interpretation of tone, as well in the comment to which I was replying. My original comment to which Nigel replied was much more in line with the ‘tone’ I was hoping to convey.

        • Nigel Oswyn

          “…a classic example of ignorance at its finest.” My but that must sound awfully good when you say it to yourself. It really has nothing to do with ignorance, it has to do with aversion regardless of any real or imagined benefit. I know its all cosmic matter in the end, but I’ll prevent heart disease in other ways, thank you very much.

          • Justin

            Then why even say anything? Why even spend the time or exert the energy stating such?

          • Nigel Oswyn

            And I will ask you the same.

          • Justin

            Because I’m of the opinion that the stuff is beneficial and that others may not be aware of it… and, upon raising awareness of it, they may become curious-enough to be compelled to research it and find it beneficial for them as well.

            Mine was to raise awareness to something not covered in the video, yours is anecdotal or personally pointed at best.

            …my thoughts are somewhere along the lines of, ‘if you don’t have anything nice to say …. ‘

          • Nigel Oswyn

            But these forums aren’t about not stepping on someone else’s “feels.” Get it? If you are that sensitive, then maybe you need to be somewhere else. I don’t eat dirt because it hasn’t been scientifically proven to do anything good isn’t saying anything “not nice.” I’m as entitled to my opinion as you are to yours. What I am saying is that if DE isn’t good for cats to lick from their paws, then it likely isn’t good for humans, not that I would do it if it were.

          • Justin

            Ha! did you really just say ‘feels’? immediately followed by ‘Get it?’ wow!

            It has nothing to do with sensitivity, it has to do with recognizing an uncouthful non-contributor when I see one and calling them out as being so. Your clearly missing the ‘scientifically’ published paper on DE & cholesterol. so, yes, there has been ‘science’ done on it.

            That you call it ‘dirt’ clearly shows your ignorance towards the material. Do you have any science backing up this cat paw licking statement?

            Frankly, I could give a hoot if you did or not… which is kind of the point.

          • Nigel Oswyn

            Ha! did you really just say “Your clearly missing…,” and “uncouthful?” Wow!

            My veterinarian has strongly advised against DE based cat litter, and I don’t like it anyway because it isn’t compostable like pine pellets, so that’s enough for me. Please, feel free to eat all the DE you want and be the lab rat. I know people who eat charcoal for their guts, but I’m not doing that either regardless of the findings.

            “Scientific studies?” So what? I’m cautious on scientific studies because they have been often used with cherry picked results to promote products for profit. Just have a look at some of these blogs to see how many “scientists and doctors once thought ….” to see that findings can get sketchy and erroneous, especially when an industry is involved. How is that being an “uncouthful non-contributor?” If you “didn’t give a hoot,” then why did you originally respond to my comment?

          • Justin

            cool. I’m glad you won’t be using it. not only does it mean more for the rest of us, it also means that your troll-like ways will be here that much less time to continue trolling their froth all over the place.

          • Nigel Oswyn

            LOL, sunshine.

          • Joseph Gonzales R.D.

            Nigel. Thanks for your thoughts on DE and remaining polite in conversation. I thought I’d weigh in and post my findings from another thread for you and Justin to see if interested. I am not choosing sides I simply would not suggest ingesting DE. The FDA has a few documents on Diatomaceous Earth here and here. I posted an older comment here for another person who asked about its use. It seems there is very little research, if any, that exist on toxicity and safety in human trials. For that reason I tread with caution.

          • Justin

            so… does that mean Nigel may be around for longer than I was thinking he might? :

          • Joseph Gonzales R.D.

            I’ve removed necessary comments from a few users. Anyone here is free to express themselves, and disagree, but please do so kindly. Let’s all try to focus on the science and not get into an internet “war of comments” I’m sure we have better things to do :-)

          • Billy Dee

            Joseph I know in general Dr Greger does not recommend eating fish, but I was wondering about rainbow trout, the rainbow trout is farmed raised in spring water in Buhl Idaho so the spring water used to run through the fish should be pure and free of dioxins etc, Yes they are fed fish feed from the ocean, but assuming the fish feed are made of small fish with minimal pollutant build up, do you believe that this fresh water trout would be safe to consume a couple of times a week? Ideally, it would be great for them to raise crickets fed on fresh green grass to feed the trout so that there would not be an impact on the ocean life. I suggested it to them but have not had any response back.

      • Enthusiast

        I’d rather eat garlic than DE, but just because something is found in a non-food substance doesn’t mean that it’s unhealthy to ingest.

        • Nigel Oswyn

          M’kay. Bugs aren’t unhealthy to ingest if cultivated properly in sterile environments, and I “ain’t” doing that either, if I can avoid it.

          • Enthusiast

            Where’s your sense of adventure??

          • Nigel Oswyn

            Ever eaten a butt hole? If not then where’s your sense of adventure?

          • Enthusiast

            There’s a ‘your mom’ joke hiding in that one…. But I’m too high class to go there ;) My point is that ‘X is in Y and you wouldn’t eat Y would you?’ is a logical fallacy.

          • Nigel Oswyn

            No logical fallacy there, just a simple comparison. BTW, bugs are loaded with unhealthy stuff, like butt holes. And where might your clever joke exist, next to the one about your dad? Anyway, my mum is dead, so you can’t make jokes about someone who no longer exists. I doubt you even know what “high class” is having referenced it for yourself. Like money, those who have it don’t talk about it.

          • Enthusiast

            First, yes it is a logical fallacy. Just because it is true sometimes, doesn’t mean it is true all the time.

            Second, you take internet comments WAY too seriously. You shouldn’t let people you have never even met control your emotional state. It’s worse for you than bug butt holes.

          • Nigel Oswyn

            Firstly, again, no logical fallacy found. There is no logical reason to eat either DE, bugs, or anuses despite any “scientific evidence” that someone claims to be factual. Popular trends are highly questionable, especially when there is an industry connected. You made the comment that it was a matter of having a “sense of adventure,” reducing the situation to a question of hedonism, not science. If it is a question of hedonism, then it simply makes no logical sense to do. There is nothing fallacious about that. Then there was an immature implication about a ‘your mom’ joke, which is in fact a diversion from the original ridiculous idea of consuming clay as a health benefit. I didn’t go there, you did. See how this works?

            Secondly, I respond to internet comments because I so choose, and don’t need your permission, like you don’t need my permission to type silly things about the “adventures” of eating DE. My emotional state is NONE of your concern. I’m astounded at the level of gullibility I find, and its impossible to avoid commenting. Ta!

      • HereHere

        There is food-grade DE, lol! I had not heard of it in clumping cat litter…in fact, I’m pretty sure it is not there because the labels says not to use it around pets. Although, when I was rescuing hens, I would treat them with DE (it’s a common practice to get rid of bird mites, and it is an environmentally friendly practice; you just don’t want them breathing it or getting it in their or your eyes/lungs.

        • Nigel Oswyn

          I know for a fact that clumping Tidy Cat brand has DE as that is what makes it work, but its not good for them because it can cause problems with their digestion. I’ve had cats for decades, but now only use pine pellets, the kind bought at farm supplies for wood stoves.

    • Kris

      I tried to find any scientific literature that shows benefits of diatomaceous earth and was only able to find this:

      Diatomaceous earth lowers blood cholesterol concentrations. http://www.ncbi.nlm.nih.gov/pubmed/9533930

      But the study was in people who were unhealthy to begin with.
      Does anyone know of any other studies on the health benefits of diatomaceous earth?

      • Justin

        there are multiple approaches of effectiveness talked about with d.e. ….. multiple ‘modes of function’ if you will, but one of them very definitely seems to be associated with the boron content it contains. If you look for, say, ‘health benefits boron’ you may find more studies. personally, i mix some Borax into my de when I take it. Boron is definitely tied with hormone balancing… including increased testosterone levels in men, and balanced estrogen levels in women. There’re a lot more studies associated with it

    • Joseph Gonzales R.D.

      Thanks for your thoughts on DE and remaining polite in conversation. I thought I’d weigh in and post my findings from another thread. I simply would not suggest ingesting DE.

      It also increases your risk of heavy metal poisoning. Pick your poison, boron or dietary pollutants. Oh wait, boron would be a dietary pollutant. Where do these people come from?

  • Nigel Oswyn

    American male reproductive organs are also at risk for neural pathway disruption or complete loss via genital mutilation, so where is the one step further concern for that? The fourteenth amendment to the constitution guarantees equal protection under the law for everyone, which, believe it or not, includes male babies. It is already illegal to remove normal healthy tissue from non consenting patients, and “I don’t like the way it naturally looks” isn’t a disease of anything but in the mind of the parent saying it. Lets not only show concern for harmful chemicals in our environment but also to damaging adolescent and infant penile dermectomy performed by quacks who care nothing for the rights of males or are too lazy to apply one of the safer and far more effective alternative approaches.

    • What are you talking about? Circumcision performed by doctors in hospitals and models in the Jewish context?

      • 2tsaybow

        I had my family insist that my first born son be circumcised and since I was a single mother I went along with their wishes. After I saw what was done to my baby in a hospital performed by doctors, I swore that I would never allow such a horrible thing be done to any of my other children.
        It was terrible (even though it would be considered a perfect operation) and unnecessary.

      • Nigel Oswyn

        If you like that euphemism, yes that is exactly to what I’m referring. Child abuse is child abuse whether under the disguise of fraudulent medicine or superstition.

    • Wegan

      My brother born in 1962 was not circumcised but it was such a common practice that my mother was billed for it anyway,

      • Nigel Oswyn

        There lies the lie of the practice. Its all about the money, which is what perpetrates it today to the tune of 1 billion annually. They also know it isn’t legal to remove normal healthy tissue, of which the intact penile derma is. If they are honest enough to stop, what will it say about the children they abused the day before? They know there will be malpractice lawsuits, and there should be, and they know they could go to prison for child abuse, which they should.

    • All babies have a natural right to all their intact, healthy organs. Become an Intactivist today, and fight for the rights of all infants, boys and girls, not to be sexually mutilated for cultural, religious or traditional reasons. Thanks, Nigel.

    • Pinchas Cohen

      I’ll try not to dwell on the lack of sensitivity of the above statement to 1.6 billion Muslims and 13 million Jews, whose religions mandate circumcision. After all, our right to freedom of speech allows us to insult anyone we please, and isn’t in a good and noble thing to remind them that they have no constitutional protection from feeling insulted and to put them in their place? Instead I’d like to discuss circumcision from a medical prospective: The wives of circumcised men have a lower rate of urinary bladder infections then do those of uncircumcised men. There is also evidence that cervical cancer rates are lower for women married to circumcised men. Circumcision is also effective in preventing the transmission of sexually transmitted diseases. In fact it’s 60 to 70 percent effective in preventing the spread of AIDS and as a result has become increasingly in demand in Africa where the disease runs rampant. This is a higher rate of protection than most vaccines offer- which as also given to children without their consent and may be potentially harmful in some cases. Fluoridation of municipal water is another medical treatment which I never consented to, which can cause fluorosis and possibley worse. The harm from circumcision however is vanishingly small. It has been practiced for at least 4000 years and has been perfected to an art, especially when done under hygienic conditions available today. Traditionally the child is given a cloth soaked in sweet wine to suck on prior to the circumcision in order to quell and protests that may arise and similarly, adults may find that a glass of Manischewitz prior to circumcision may bolster their resolve. However it’s best to circumcise a child on the eighth day of his life when the chance of hemorrhage is lowest due to his having a higher level of prothrombin in his blood than on any other day in his life, because his skin is more tender than an adult’s and because he is too young to form any lasting memories which might otherwise be traumatic at that age. Because circumcision is so effective and so rarely causes harm, I would argue that it should also be made mandatory without the child’s or parents’ consent. Of course, to be fair, religious or philosophical exemptions should be given for people who worship Satan or who celebrate evil or disease.

      • Pinchas Cohen

        I also forgot to mention that adults who have undergone circumcision report no difference in sensitivity or enjoyment of intercourse before and after the procedure.

        • Nigel Oswyn

          Oh yeah, those adults in denial or who grew up with the retained sensitivity in their glans that the prepuce offered for proper development? They are adults, but I don’t care what they did as adults. I’m concerned about children who have a right to grow up and decide for themselves when they are of age and know what a penis is. What about the ones who didn’t make it to adulthood because they died, or the ones who lost their penises entirely from necrosis, like the boy in the news story last year? How many have to endure injury and disfigurement and death before its the right number for you to realise this is child abuse at any number? I know many men who want to do serious harm to their childhood mutilators, and have experienced great sexual dysfunction after they’ve discovered what is missing. Men deserve not to be sexually categorised and subjugated any longer. We are people, not objects on which to practice superstitions and pseudo science.

      • Nigel Oswyn

        Yours is a typical response of rhetoric and straw man arguments. Its a good thing I don’t waste too much time arguing with child abuse enablers who repeat the broken record AIDS nonsense that has been disproven in Europe. Maybe you need to consider that babies don’t have sex and therefore don’t require HIV intervention. I don’t care if you are a three headed ape from mars. Religion is no excuse to deny Jewish boys their rights to their bodies. Doing so is anti-Semitic. Luckily, many Jewish boys in Scandinavia and Russia don’t fall victim to this superstitious act, and they are still quite Jewish. Eighty five percent of men internationally are intact and living proof that genital mutilation, euphemistically called “circumcision” is a lie. The only ones promoting it are the ones with the scars who have given scars. Let the “art of ‘circumcision'” be left to the fetishists for adult bodies, not those of children.

        Salicylate sensitivity. Please report on this. Makes a huge difference as far as ADD for
        lots of kids when they reduce high salicylate foods, or omit these foods completely from

        • Joseph Gonzales R.D.

          Sure thing! Only one study I could find. There does not appear to be a link with salicylates and ADHA.

      • Oh hurry! Above I replied to Tobias’s post with my questions having done some version of the 5:2 fast for about 3 years. Is it worth it?

      • HereHere

        Please give us an update on IgG diet analysis. I have two friends now who are following this seeming pseudoscience. One of them has been avoiding foods such as strawberries for 2 years now. I can’t find much on PubMed, and the dietetic associations have no position statements on these. The one dietitian I spoke with about this rolled her eyes and gave me info on fibre to give to my first friend who went on the diet. (His problem is constipation, and he basically doesn’t eat much fruit and veg). People are really illogical.

    • guest

      Daily fasting reportedly promotes autophagy.

    • Stewart

      Sure glad you mentioned this Tobias. I have been wondering about this a great deal and have yet to see anything convincing one way or the other. I have seen claims made but based on what evidence I do not know.

      • Tobias Brown

        Maybe Dr Greger has made one or two posts on this already… Not sure. He’ll likely say that some types of fasting are very beneficial but our diet approach here can lead to very similar results longer-term.

        Personally, I have a small issue with weight control, nothing by the standards of the American masses today. (Attempt at obscure pun made there.. :), as I merely add 15 lbs each winter, which are extremely harsh in my area, from my ideal <155 lbs, and I expect that water fasting one day per week might be the answer for me, at least whenever I rise above my target weight.

        I finished my first water fast this morning doing 32 hours. Not expecting to eat during the day seems to help to keep down feelings of hunger. Having something interesting but not too challenging to do all day seems to help too. It was much easier than I expected with the hardest part being going to bed after 26 hours, though falling asleep wasn't an issue. (I awoke at 1:30am and had two apples with cinnamon.) Weight scale results were incredible.

        My read on it is that intermittent fasting offers incredible health benefits. I expect that experts will give it the green light yet the returns for non-serious health issues likely fall off steeply, so some relatively short fast can have a huge impact. So, I can't wait to see what our doctor says on this question.

    • Joseph Gonzales R.D.

      Stay tuned for more from Dr. Greger on fasting. In the meantime, I think that water fasting can be extremely dangerous in uncontrolled environments without doctors approval. A quick search on PubMed shows fasting for one day may have some benefits to reducing heart disease, however, I would never suggest it do the lack of research. Water fasting seemed to help those with hypertension, but this was conducted in a controlled environment within a clinical study. There is far more research on the efficacy of plant-based diets for hypertension and heart disease. One of our site users provided a great link to a clinic that focuses on fasting. His comment can be found here.

    • For about 2 years Kevin and I have been doing the 5:2 fast diet Dr. Mosley popularized on a fascinating BBC special. Eating normally for 5 days and “fasting” for 2. Fasting here means 4-500 cals. a day for women and 6-700 cals. a day for a man. It is doable, but on stressful days, my hunger distracts me from writing and office work. For the last 8 months or so we have fasted from 9pm until dinner the next night and that dinner is light, probably 1500 calories. We do not sleep so well on the lower cal version. MY QUESTION: by very low calorie fasting 2 x a week, do we do harm by omitting all the benefits of WFPB in normal amounts? No question this helps control weight, improves our taste delight in eating on non-fast days, and does give us a mini-vacation from eating and food prep!
      I asked Dr. Fuhrman about it and he responded that if he fasted he would be too thin. So, we too have many questions. Dr. McDougal has some patients fast and tells of grand results with some illnesses. And is there good evidence that apoptosis and other healthy invisible events are worth the effort and better than eating a super WFPB diet?

    Is there any truth to “detox” claims. We often hear things like juicing can create “.. detox symptoms, rashes, headaches, etc. temporary things as their body is cleaning out.” Does this really occur? Negative symptoms as we juice, or as we improve our diet (which juicing isn’t always a good example of).

    Just a quick look at the list for the contaminants. It appears that human milk is the third highest cause of dietary pollutants (0.42). That is interesting and a little scary.

(1.) i was told by an acupuncturist within a top fertility treatment center that i should consume ANIMAL PROTEIN after my embryo transfer and during pregnancy. this seems contrary to what i have read over the years. but shouldn’t they be experts on getting results? the number of live births from successful pregnancies helps their business continue, so i think they have a stake in positive results, and it makes me tend to believe they’ve got something valuable to say when it comes to growing and birthing a healthy baby. so what the heck, how can animal protein be bad when all the western fertility specialists (and i actually saw an eastern specialist too) and all seemed to believe animal protein was important for conceiving. this leads me to guess that maybe it is really just the industrial pollutants within the animal meat/dairy that is the real problem here??? the fact that they are not running free in the wild without acid rain, for example??? i was all thinking that a veggie diet was so much better than meat/dairy until the fertility specialists (many!) told me to eat animal protein….. wth? (question #2.) i read that dha is so important for babies and children BUT that children do not have the enzymes or “whatever” is needed to utilize or convert flax oil to provide the right omega 3’s they need. so i think about a “fish oil” supplement. but i also hear that even the best filtered fish oil still contains stuff like pcb’s and mercury, etc. so what can i give my toddler?? nothing?? wouldnt that be harmful to leave out an essential fat? i want his brain to develop well! the homeopaths and “crunchy” moms all use cod liver oil. and the one time i cut open a prenatal DHA capsule from algae source, and spread it over toast, and it tasted and smelled strongly like metal. huh?? i thought the algae was supposed to be metal contaminant-free??? and it smelled so bad there’s no way my toddler would take it, but that’s beside the point. the metal smell made me doubt it’s quality. and it’s the only brand i can find based on algae. back to the cod liver oil, it generally sounds like a bad idea to eat livers, since livers filter toxins?!?!? i dont think we want fish liver toxins of all the animals! By the way, I still nurse my toddler so I realize he is getting DHA thru human milk, but we do need to wean soon! AND if all my DHA is “switched off” to go into my breastmilk, then don’t i need to take a supplement so that my own brain does not get depleted? i have read that the 3rd or more pregnancy has much higher risk of problems such as learning disabilities in the child because the mother has become depleted in DHA. and i plan to have a few more pregnancies so what should i take?? (question #3) so i hear about how vitamin D and the ratio to A and C and magnesium and everything else is super important in preventing sickness and flu during flu season, so all the homeopaths/crunchy moms again use cod liver oil because it has the right ratios of vitamin D and A and also has omega 3, etc.. So I give myself straight vit D drops (i am still nursing this toddler) not knowing about the “ratio” and had negative results (umm pink eye in both of us, NOT at the same time lest you think one of us spread it to the other, which supposedly can result from low vit A). So i am told “give vitamin D” but the best way to do it is with fish livers? by the way i had an esteemed urologist tell me of the many many people (outdoor farmers!!) she tested, nearly all were deficient in vitamin D in their blood, so the sun just does not cut it for providing vit D anymore. If the texas farmers cant get enough D, then my 10 minutes playing outside are not going to cut it either. (question #4) SOY ok so back in college i heard from the animal rights activists to eat less animals so i changed over from a SAD to a high soy, high fake meat and soy milk diet. probably a lot of glutamate, msg, hardly any vegetables, etc. WELL let me tell you i am a woman, and i began growing chin hair! i never had it before that time, and my mother and her mother and my dad’s mother never had that problem. by the way, i was raised on soy formula as a baby, but my thoughts are that soy is bad!!!!! i hear that there are benefits but my chin hair every day makes me believe it does not agree with me!!!! and then just a general thought for (question #5) i have fast metabolism, especially nursing a baby. so there is no way vegetables are going to fill me up for longer than 5 minutes. i have drunk large cups of veggie juice and still do’nt feel satisfied. what is the answer??? in the beginning i thought soy was so filling, but you know my feelings about soy now! and potatoes and fat are filling, but aren’t we supposed to limit potatoes and oils????? so, what are we supposed to eat? currently my toddler only eats human milk, MEAT his favorite thing, and fruit and cheese and yogurt. he does not like any kind of veggie or even fruit juice or smoothie. now what? thanks for your time this was a super long post.

      and by the way my toddler has mild allergies and mild eczema, when i give him a fish oil which is high in DHA (wiley’s finest brand) the eczema nearly disappears. doesn’t that mean he needs the oil? and he was never given formula nor vaccinated, and i am not trying to start a debate about vaccines, just saying that neither formula nor vaccines can be responsible for him having allergies. AND he has a severe food allergy to NUTS so they are out. Peanuts are ok but aren’t those not-so-good for you? thanks!

      • Wade Patton

        Please feel welcome and do search through the 8 years of articles and videos archived at this site. Also you may find specific answers in the comments under each one. Peanuts are fine for adults, but I have not studied infant nutrition at all, but say be thorough and be meticulous, but do learn as much as you can from plant-based MD’s. You couldn’t have found a better resource than here. The most famous pediatrician of all time, Dr. Spock http://en.wikipedia.org/wiki/Benjamin_Spock , recommended plant foods only for infants and children.

        Is peanut butter good for you? – it seems okay!

      sorry if forgot one more piece of confusion.. i hear about the weston price “activator x” which is a special form of vitamin K (not what you get from green leafies) that you get from raw dairy, so wth now I have to have raw cow’s milk??? because the vitamin K in greens is not the same form?? i think it is called MK-7??

      • Weston price is a hack organization.

      • Joseph Gonzales R.D.

        Good question. Dr. Greger addresses Vitamin K2 in his Q & A. See if that helps? Thanks!

    • There is no nutritional reason in the world to prefer animal protein to vegetable.

      There is so much conflicting information out there by so called “experts,” that it’s no wonder more people aren’t confused. My solution is to for get what doctors- not trained in nutrition- say and to rely on common sense and history. Prior to the availibility of refrigeration in 1913, very little meat was eaten. The average American didn’t even eat 5 pounds of chicken back then, and supplements were unheard of. and yet, with the exception of childhood and communicable diseases, people were generally healthy. Chronic diseases were very rare. In Africa to day, people seldom are ill or obese and their basic diet is whole grains. The same was true in Asia 30 years ago. I find myself thriving and rarely sick eating whole grains, legumes, vegetables, fruit and a small amount of nuts and seeds only. No processed foods, no oils. Over the years Dr. Greger has given ample evidence that our natural diet is an unprocessed plant-based one. It’s hard to argue with success.

        thanks this is the kind of input i am looking for!

    • Joseph Gonzales R.D.

      So many complex questions. Are you able to see a dietitian? I would suggest that for individualized help with you and your toddler’s diet. If that is not an option I suggest the Vegetarian Resource Group as they have research on kids and nutrition, soy formula, etc. For kid snacks I love this brochure by PCRM. They also provide thousands of recipes, here. Dr. Greger’s Optimal Nutrition Recommendations may also help. Ellyn Satter’s division of responsibility in feeding is a great resource, as well. See if any of these links help answer your questions?

      Thanks,
      Joseph

  • Garlic is ok, but it may decrease your ejaculatory latency. :-)

    Is calorie restriction necessary for weight loss? See the ongoing and raging debate between those like Durianrider and those like Loren Lockman…

    Looking at the chart at the 1:45 mark, I think the statement should have been “predominately in freshwater fish”. Ocean fish on the chart is way low by comparison. Which to me means that if I want to eat fish occasionally (in sushi or whatever) to try to make sure it is of the ocean variety.

    With regard to Diatomaceous earth, I came here previously when I read some stuff about it hoping that perhaps Dr. Gregor had done a video on whether the claims are supported. I bought food grade DE to deal with flea beetles in my garden (they were eating all my baby plants), but it is clearly labeled for use in animal feed as an anti-caking agent as well.

    I haven’t tried any myself yet because I’d like to see something comprehensive on it done, but I have read many places where people feed it to their pets and take it themselves for various reasons. Maybe I’ll google around some more.

    • Joseph Gonzales R.D.

      Good point. Thanks for sharing. Note that other foods on that list were also low, but there may be other reasons beyond pollutant levels that warrant caution.

      What are the claims on DE? I have not seen them. There is a lot of research about DE but nothing I found promotes it safety or use in humans. Happy to discuss more! Other’s have commented on DE before so perhaps they can enlighten us if I’ve missed something? Thanks, Doug.

    I have found a significant drop in sex drive since going on a low fat vegan diet. Is there any science on this? Is it the dietary fat percentage, or something else? Thanks

    • Guest

      I have experienced something similar. I have tried to follow the “How Not To Die”/”Daily Dozen” approach or something similar for a year or so now. In that time my sex drive seems to have dropped to virtually zero, although I recently confirmed that I am not impotent. My testosterone level was tested multiple times and it is much lower than the normal range. I was referred to an endocrinologist, and she has prescribed Dexamethasone 1mg. To be honest, I am not sure what the exact reasoning is for this prescription. I am married, 34, no other major health issues I believe, though I guess I should say I might have hyponatremia because of the low-sodium part of this type of diet and that has also caused some concern with my general doctor. I have some swelling in my legs and my feet get very swollen during the summer when it is humid — my regular doctor thought this might be a kidney issue and referred me to a nephrologist. I use a standing desk, by the way, which might partly cause the foot swelling.

    Please make a video addressing beef gelatin as a testosterone boosting supplement–pros, cons, etc.

    Thanks
