Doctor's Note

Cutting down on sugary foods may be easier said than done (see Are Sugary Foods Addictive?),  but it’s worth it. This video is part of an intermittent series on the dangers of high levels of fructose in added sugars. See the first two installments in How Much Added Sugar Is Too Much? and If Fructose is Bad, What About Fruit?

That’s where I show the berry-blunting effects.

What’s this about being in oxidative debt? See my three-part series on how to pull yourself out of the red:

Ironically, fat may be more of a problem when it comes to diabetes than sugar; see:

    Once again whole natural foods win by a landslide!
    Thanks Dr. Greger and Staff!

  • Plantstrongdoc M.D.

    Makes perfect sense. Fruit: Fructose, fiber, vitamins, minerals, flavonoids, lignans, stilbenes, phenolic acids. No doubt that polyphenols prevent (and treat) various diseases. On the other hand, breakfast cereals: Sucrose, high fructose corn syrup, salt, trans fat, artificial color, artificial flavor, artificial sweetener, bleaching agent, preservative, stabilizer, white flour and a flavor enhancer – Bon appetit….

    • etmax

      Well I purchase a breakfast cereal that contains no added sugar (only
      what’s already in the dried Goji berries), no added salt, no corn syrup,
      only trans fats if they’re already present in the nuts & cereals
      present, no stabilizers no white flour (no wheat in fact) certainly no
      flavour enhancers. This is the way it comes out of the box. It has way
      more fibre than any fruit. I think if you’re going to make a comparison
      like this you need to specify a fruit by name and a cereal by name, like
      apples compared to Froot Loops. Rolled oats is also a breakfast cereal.

      • Hunter,

        But that fiber is not water rich, thus it causes a mucousal reaction, which certainly does not aid in digestion, absorption or utilization of the the nutrients listed on the side of the box.

    These studies seem to be repeating what Walter Kempner, M.D. did many years ago with the rice diet at Duke University which started in 1939. This is where he fed patients only rice, fruit, juice and sugar and they lost hundreds of pounds of weight, reversed their chronic kidney disease and a whole host of other chronic problems. Simply put we should live Fruitastic lives. Again thanks for this great Fruitastic eduvideo!

    • Bob413

      This is a lie and that study was a fallacy. There were many things covered up in that study including the fact that not everyone followed it. The people who didn’t follow it lost weight while the others who did, gained. The entire study was grouped as a whole and called it proof so to speak. Proof of what though? A diet high in rice, fruit juice and sugar, causes weight gain? Then yes it proved that, but that’s not what it they reported.

  • Julot Julott

    Subtitles where are you? :D

    • Joseph Gonzales R.D.

      Please click “View Transcript” to read the text from the video :D

      • Peter

        I was very happy after subtitles became available again after the change to Vimeo. Most of the times there are short references in the videos where it is good to know which exact sentence is said at an exact moment, so subtitles are extremely useful.

        • Joseph Gonzales R.D.

          I’ll ask our team about the option to use subtitles. Thanks Peter.

        • Joseph Gonzales R.D.

          Have you clicked the CC within the video? We do have subtitles!!!

      • Julot Julott

        Thx, i never clicked on it before, they added it to the video though~

    • Joseph Gonzales R.D.

      In the video you’ll see a “CC” – click that and subtitles pop-up.

      • Julot Julott

        Yes i know but this button wasnt available on day 1~

  • DStack

    Fruitarian here – thanks for finally making a video on this subject, Dr. G! Fruit for the win!

    • Joe

      Fruitarian diets are dangerous in the long-run and lead to major nutritional deficiencies such as zinc, selenium, EPA/DHA and iodine. Not to mention very low-fat diets are bad for overall cognition and hormonal functioning. Fatty fruits like avocado contain way more omega-6’s than omega-3’s, furthering hindering ALA to EPA/DHA conversion (on top of the very low amounts of dietary ALA to begin with). The whole anti-fat/low-fat dogma days are coming to an end. Inflammation causes heart disease, not fat or cholesterol. That is all.

      • Ron

        Flax for omega 3 and Brazil nuts for the rest. Fruitarian doesn’t mean you ONLY eat fruit, my friend. Did you really come to Nutritionfacts.org to say that cholesterol does not cause heart disease?

        • Joe

          If you think cholesterol causes heart disease, please take no offense but you are simply ignorant on the subject. Cholesterol is drawn to protect from excess inflammation, it is not the CAUSE. Inflammation from toxic fats such as trans fats or overcooked animal products, rancid oils, excessive omega-6’s, etc. is what causes heart disease, not fat in general. You’d still need to account for iodine, sodium, and balance out your O3:O6 ratio for optimal conversion considering ALA to EPA/DHA conversion rates are very low. Higher for women than men, however.

        • Arto Beck

          The above poster is talking about DIETARY cholesterol and fat. The FDA agrees with him as they just removed cholesterol limits from its dietary guidelines. So yes, the cholesterol that we eat does NOT cause heart disease.

          The above poster has it right. Inflammation causes the liver to produce LDL cholesterol to patch the lesions caused by the inflammation, a little like a band-aide. When the inflammation subsides the liver sends out HDL cholesterol to remove the LDL patch and everything goes back to normal. Why HDL is “good”: it’s cleaning up the patches and suggests there is not chronic inflammation.

          Heart disease starts with chronic inflammation. The liver does not send out HDL to remove the LDL patch because the inflamed state has not been reduced and in fact sends out more LDL because there are more lesions from the constant inflamed state.

          The unremoved LDL cholesterol is what clogs the arteries and they are a symptom of inflammation as the poster above stated.

          • Thea

            Arto Beck: I recommend you take a look at this article which explains how the FDA got to their initial conclusion (which later got reversed): http://blogs.bmj.com/bmj/2015/04/28/neal-d-barnard-and-angela-eakin-yes-cholesterol-matters/. Very important details. As they say, the devil is in the details.
            .
            And, as it turns out, when it came to the final/actual guidelines that got released (as opposed to the preliminary floater ideas), the FDA did the very opposite of removing cholesterol limits form its dietary guidelines. The FDA got forced to actually acknowledge the science. In the end, the FDA strengthened their warning about cholesterol. You can read about it here: http://www.pcrm.org/USDA And here is a quote:
            .
            The Guidelines state: “As recommended by the IOM, individuals should eat as little dietary cholesterol as possible … Strong evidence from mostly prospective cohort studies but also randomized controlled trials has shown that eating patterns that include lower intake of dietary cholesterol are associated with reduced risk of CVD, and moderate evidence indicates that these eating patterns are associated with reduced risk of obesity. … Dietary cholesterol is found only in animal foods such as egg yolk, dairy products, shellfish, meats, and poultry.”
            .
            Sometimes the truth really does win. The problem is that many websites and the media didn’t bother to report what actually happened. If I were you, I’d be darn mad that the sources I rely on for good information did not inform me of this situation. Perhaps it is time to get some reliable sources of information!

          • Arto Beck

            Thanks for the info as it reminds me never use a coincidental confirmation to make a point, especially when it is from the USDA. Very helpful to remind me and everyone that when a big (fill in the blank) group agrees with you it’s probably for the wrong reasons.

            I will still agree with the above poster that the causes of arterial cholesterol have little to do with dietary cholesterol and everything to do with inflammation.

            You can point to study after study, as we alternatives have ours as well now, and especially with prospective cohort studies (which seem to be the majority of the studies they are referencing in your article), you will find that it’s almost impossible to make properly controlled study on humans for dietary habits to prove anything. There is always more than 1 dietary variable especially in prospective cohort studies, that render the experiment a non-controlled study and open to interpretation.

            As in the case of this video above. The Jenkins study is titled “high-fiber vegetable, fruit and nut diet”. That is 3 variables with different nutrient components with fiber being the common denominator. But we’ve got Dr. Gregor here inferring it as proof we can “eat all the fruit that you want” (over 200g/day of fructose in one stated example), 20 seconds after hearing the toxicity level of fructose is 50g/day. How is that possible? Then we are distracted with poop jokes to avoid the elephant-in-the-study fact and contradiction to good science that not only were there were vegetables and nuts in the study, the vegetables were at 10x the recommended serving or the practically impossible 6lbs/4kg per day.

            So you might be able to say that fiber negates the effect of super-high fructose toxicity but any concrete determination about fructose toxicity (and the point of this video) is scientifically moot.

            And again this article is spreading the same problems that the USDA has. So many posters are commenting for joy and telling their friends that they can up their fructose level with fruits, don’t worry about fructose toxicity, because this Dr. said so on this website that gives “nutrition facts.” It’s a .org for fruits sake, they can’t be misleading us!

            I understand the public’s frustration because they are getting it (badly) from all sides, this video included. You can see a small population of commenters who believe as I do throwing up their hands at such unscientific reasoning perpetuating poor nutrition. Shortly the public can get a combination scientific, historical, traditional and engineering perspective on nutrition and finally have some guidelines on what to do.

      • ScottieDOESknow

        Joe with the April fools joke. Nice1.

      • http://www.potatostrong.com/ Will Kriski

        Sorry Joe we can’t take you seriously if you dispute the dangers of animal products after all the studies that are out there.

      • http://www.christiansolorzano.com/ Christian Solorzano

        So in addition to fruits we need to consume vegetables, grains and nuts. Will those additions to fruits cancel out the “dangerous” side effects to being a fruitarian?

        • Natalie Lenka

          Monkeys don’t eat all fruit. High greens and some nuts for the win. Vegetables and greens are beyond essential.

          • Donna Witkowski DiPietro

            Depending on the type of monkey, they also eat insects and small rodents…

      • Jeanne Van Den Hurk

        Joe, inflammation doesn’t appear from no where. Possibly the single greatest cause of inflammation is animal-based food.

      • Natalie Lenka

        Who says you can’t take supplements as a fruitarian? :) Leafy greens have an amazing 3-6 ratio and should be a large part of any balanced fruitarian diet by volume.

  • Mark

    I wish you had also mentioned the results of the israeli date study: http://nutritionfacts.org/video/are-dates-good-for-you/

  • MikeOnRaw

    Woot, so glad to see this one finally as I saw it coming. Here are shots from yesterday on cronometer. I average about 319grams of sugar from fruit per day and I often have people questioning it being too much. I think we all know it is fine, assuming our variety gets us the nutrients we need. But I’m glad to hear our thoughts are correct so far.

    • Arto Beck

      You said that paramount in a diet is one that “gets us the nutrients we need”. Fruits have a low nutrient density (variety of nutrients), low quantity (absolute levels of each/any) and poor nutrient/calorie, nutrient/sugar ratios next to vegetables, legumes, and for those that eat them animal products.

      The banana that you eat so much of is double the average fruit in the quantity of fructose, and only average or worse than the average fruit in the 20 major vitamins and minerals. It’s supposedly high potassium content as well as higher than average-fruit magnesium content might be high for fruits but both are below the average quantities for vegetables.

      In fact there is no vitamin or mineral that exists in higher quantities in normal fruits than in vegetables, and most vegetable vitamin and minerals averages are 2x or more than fruits. Except of course sugars, carbs and calories where the average fruit has 3x the amount in that category.

      My numbers are based on the USDA nutrient values and comparing 22 fruits and 29 vegetables. When I say “normal” fruits I exclude the exotics like camu camu (8x the vitamin C of parsley)

      • MikeOnRaw

        And yet while the fruits do have low nutrient quantity, they are there. And you can get enough of the nutrients you need eating fruit.

  • https://www.facebook.com/app_scoped_user_id/10153096096543115/ David Clayton

    This European study suggests to me that the sweet spot for meet consumption is 10 – 19.9 g/day and going down to 0 – 9.9 g/day had an adverse effect HR. Am I reading the study right?

    http://www.biomedcentral.com/content/pdf/1741-7015-11-63.pdf

    Any comments are welcome

    • Joseph Gonzales R.D.

      Hi David. I am not sure about a sweet spot for consumption? To me it seems the more red and processed meat consumed increased total mortality, compared with those eating the least meat.

      • https://www.facebook.com/app_scoped_user_id/10153096096543115/ David Clayton

        Soo, in said study, you did not notice a small up-tic in HR when meat consumption fell below 10 – 19.9 g/day?

        • Anthony

          On a cursory glance of the paper, the spot you mention is not really much different than its neighbors. What’s not clear is why there are no confidence intervals on that intake level. It seems they might have chosen a singular data point on that level to represent a consistent reference and it was probably the smallest point in the set. However, there should still be confidence intervals. Even looking at the table, though, you see those singular reference points, in most cases, fall inside the 95% confidence limits for both the category before and after. If the confidence bounds were included, that would happen for all cases. The difference there is not statistically significant and what seems to be a “sweet spot” is probably an artifact of how they chose that reference point.

          • nodelord

            Ok, I guess we still think, eating just the smallest amounts of meat from time to time will be bad for our health, correct?

          • Anthony

            Based on nothing other than that paper, what I would conclude is that there is an obvious upward trend in effect (hazard ratio) associated with increased meat consumption, but I could not reasonably conclude that there is some point where the effect increases with decreasing meat consumption (i.e. there is a “good” amount of meat to consume). That’s a conclusion unwarranted given the uncertainty in the data.

            In general though? I believe what you said is probably true and that’s how I view eating meat, but I haven’t done any thorough analysis of the literature. You’ll have to ask the nutritionfacts.org guys. :-)

          • Joseph Gonzales R.D.

            Agree. Did not reach statistical significance and even reports on why the possible J-shaped curve.

        • Joseph Gonzales R.D.

          I think I see what you were reading. You are right, when the consumption dropped in some categories to 0.0-9.9 g/d there was an up-tic, but I don’t think it reached statistical significance therefore it could have been due to chance. Then I see the researchers discuss this more, ” The EPIC results
          do not show the lowest relative risks (RRs) for subjects in
          the lowest meat intake category, but a slight J-shaped
          association with the lowest risk among subjects with low-to-moderate
          meat consumption. This was observed for
          red meat and poultry. Also, taking into account the
          results from the studies that evaluated vegetarian and
          low-meat diets, it appears that a low – but not a zero –
          consumption of meat might be beneficial for health. This
          is understandable as meat is an important source of
          nutrients, such as protein, iron, zinc, several B-vitamins
          as well as vitamin A and essential fatty acids (linoleic acid
          and to a minor extent eicosapentaenoic and docosahexaenoic
          acids also). A sub-optimal supply of some of these
          nutrients due to an unbalanced type of vegetarian diet
          seems possible and might be associated with an increased
          risk for morbidity and mortality. However, support for
          this hypothesis from the literature is not strong, especially
          when looking at the population level. Alternatively,
          subjects with very moderate meat consumption may
          be the group with the highest proportion of healthconscious
          subjects who also try to optimize their diet (as
          part of a healthy lifestyle).
          In contrast to the US results, we observed a consistent
          association between processed meat consumption and
          total mortality but not between red meat consumption
          and total mortality. Processed meats such as sausages, salami
          and bacon have a higher content of saturated fatty
          acids and cholesterol than fresh red meat; the latter is
          often consumed after removing the visible fat tissue,
          whereas the proportion of fat in sausages often reaches
          50% of the weight or even more. Both high saturated fat
          and cholesterol intake have been found to be related to
          the risk of coronary heart disease”

          • nodelord

            I guess if one is thinking objectively, it is possible (based on these findings) to see how diets like DASH, Mediterranean and Paleo garner some merit. BTW, thank you so much for your in depth response :)

          • BeoCode

            So basically, if we eat well balanced vegan diet, it should be good. We can get protein, iron, zinc, several B-vitamins

            as well as vitamin A etc from other sources rather than the rotting animal flesh.

  • Arun Mukherjee

    This is wonderful to know as I care for a diabetic who has now reversed it. I would like to know if diabetics can consume dates. And if yes, how many?

    • Diabetesiscured

      I was a severe type 2 diabetic and I reversed it with high fruit diet. I was off my blood sugar medication in only 10 days. However, I was not able to eat dates for about 30 days. After about 30 days, my insulin response to dates is very good and I can eat as many as I like. I highly recommend waiting until your diabetes is completely gone for a month before trying to eat dates, and check blood sugar when you add them to see how you respond.

    • Joseph Gonzales R.D.

      Hi Arun. I think It depends on the person and the quantity of dates eaten. Some diabetes may experience extremely high bursts of sugar pending current glycemic levels and medications if they overdo dates. For most, dates should be fine, but i think it depends on other foods eaten in the diet. Dates do have fiber and other nutrients that can be helpful. Someone mentioned them below (Thank’s Mark!), I’ll share here.

      Thanks,
      Joseph

      • Arun Mukherjee

        Hi Joseph. Thank you for your answer. No, we don’t go overboard with dates, but do like to sweeten our occasional dessert with them.

      • http://www.eatandbeatcancer.com/ Harriet Sugar Miller

        So tell me if this is correct–The glucose in fruits, not the fructose, causes the blood sugar spikes but polyphenols seem to help control those spikes. The problem with too much fructose is that it can increase uric acid, causing gout (and any other problems?) . Plus, fructose doesn’t cure hunger (doesn’t induce a satiety response). Is that correct?

        • http://www.eatandbeatcancer.com/ Harriet Sugar Miller

          I also read somewhere that fructose is responsible for the sweet taste of fruit and that glucose is not sweet-tasting. Is that correct?

        • http://www.eatandbeatcancer.com/ Harriet Sugar Miller

          I just re-read Dr. Greger’s earlier post on fruit juices. Darryl points out that 25 grams of fructose is about all we humans can absorb at one time–and that malabsorption at higher doses could cause intestinal problems. From those fructose charts referred to somewhere above, it seems that eating a piece of fruit is well below the 25g limit (Exception: a cup of raisins has a whopping 43 grams–not to mention its glycemic impact).

          Could you tell us how much fructose is in a cup of orange juice, apple juice and my current favorite, blueberry juice?

    • Charles

      What did you do to reverse the diabetes for that person?

      • Arun Mukherjee

        Hi Charles. The diabetes was reversed by strictly adhering to a whole foods plant based no oil diet. And we ave been on it since January 2014.

        • Charzie

          Ditto here, six years!

          • Arun Mukherjee

            Wonderful!

  • HungryShrew

    Why did the ultra high fruit [fruit sugar] diets not result in adverse effects?

    I understand there’s something ‘bad’ about added sugars, but what’s going on, what’s difference does it make to our bodies?

    • Diabetesiscured

      I used to have severe type 2 diabetes and I checked my blood sugar often. If I ate an ear of GMO corn, my blood sugar would spike to 300! I can several ears of organic corn and my blood sugar stays around 100. Something about the fructose is altered in GMO corn and GMO sugar beats, which affects the way the liver processes it. High amounts of GMO fructose causes liver problems and high blood sugar. I eat unlimited amounts of non-GMO fruit daily, and it healed my type 2 diabetes and my blood sugar is perfect now.

      • Charles

        Can i ask specifically what did you eat? tell me what you ate in 1 day for breakfast lunch and dinner Please.

      • Donna Witkowski DiPietro

        And, that is why I think any study on food should make the distinction between GMO/non-GMO foods and grass fed vs conventionally fed meat. I think it can change the outcome, and isn’t appropriately conclusive.

    • mik

      the difference is all the other good stuff inside the fruit. We find new micro nutrients all the time. So all plants can easily have many things in them that we just haven’t found yet or things we have found that are great for us and not present in refined products.

    • Joseph Gonzales R.D.

      I’m not sure. it may be something to do with the fiber in fruit helping to reduce glucose spikes.

      • MikeOnRaw

        This was discussed some in this video http://nutritionfacts.org/video/juicing-removes-more-than-just-fiber/
        possibly the phytonutrients

      • Lea

        But would that mean that adding sugar to meals high in fiber also doens’t have adverse effects?

        • Joseph Gonzales R.D.

          I don’t think so. Fruits have natural sugars that work with their fibrous environment. Adding plain sugar to high fiber foods is not the same thing, and as Jay M and MIkeOnRaw pointed out it may be the phytonutrients (antioxidants) that are helping, as well.

    • Jay M

      Fruits are accompanied with beneficial components including polyphenols that acts as antioxidants and modulate cellular metabolism.

  • Duke

    What a out 100% fruit smoothies?

    • Diabetesiscured

      I drink them every day and my diabetes was cured. Fruit smoothies keep my blood sugar optimal, my last A1C was 4.7.

      • CharLee

        If you mind me asking, how severe were you and can you tell me what foods did you specifically eat? Can you eat like a normal person such as 2 cups of brown rice or other things like that?

  • Johanna

    Dr. G, this reminds me; I just tried one of the breakfasts you said you had on a Google talk: sweet potato (but I used kabocha squash,) dried berries etc. (I used frozen blueberries, black raspberries, and blackberries,) and cinnamon. It was simple to fix and great! I’d like to hear more of what you eat.

  • Alex

    The video mentions benefit from berries to wheat and rye, and then 75 g or 1/2 C of blueberries to a typical high-carb low-fat sugary breakfast cereal. Should we expect negative ORAC before introducing blueberries to a healthier breakfast, such as oats, cashew milk, almonds, apples, fresh ground spices, flax, and a Brazil nut?

    • Joseph Gonzales R.D.

      Not sure I would expect negative ORAC values, but perhaps very low. ORAC levels alone are not something to base our food choices, as I don’t think they take into account other variables (protein, calcium, fiber, etc). Of course, good to boost our antioxidants from whole food sources.

    • psisai

      I’m not an expert by any means, but for myself, grain and vegetable based breakfasts don’t do me any harm. So adding fruit can only be extra goodness to your anti-ox levels.

  • Diabetesiscured

    I eat a diet very high in fruit, which cured my severe type 2 diabetes. However, I am still having very high uric acid levels. Does a high fruit diet cause high uric acid? I have tried remedies such as alkaline water, cherries, yoga, eating more leafy greens, drinking 3 liters of water a day, but my uric acid level is still too high. I have been vegan over 2 years, and I only eat fruits, veggies, leafy greens, and nuts. How do I lower my uric acid?

    • Mark G

      Sorry to hear you’re having that problem. I don’t have an answer for you, but I have a question. You don’t list whole grains or legumes & pulses (beans, peas, lentils, etc.), are these in your diet? I’m wondering if that type of fiber and other nutrients they provide might help, as suggested by this study on pub med. http://www.ncbi.nlm.nih.gov/pubmed/12350076
      I’m not sure if you’re limiting some plant foods because of potential purine content. I’ve seen comments elsewhere that purines from plant foods do not affect the body the same way as those from animal products. So I wonder if it’s like protein and iron where the plant sourced ones don’t seem to negatively affect much, but the animal ones do.

      • David Johnson

        >>>I’m not sure if you’re limiting some plant foods because of potential purine content. I’ve seen comments elsewhere that purines from plant foods do not affect the body the same way as those from animal products.

        Right plant purines seem safe:

        http://www.nejm.org/doi/full/10.1056/NEJMoa035700.

        “We did not find a significant association between gout and the consumption of purine-rich vegetables, either as a group or individually. The variation in the risk of gout associated with different purine-rich foods may be explained by the variation in the amounts and types of purine content and their bioavailability for purine-to-uric-acid metabolism.5,17-21 It has been suggested that moderation in dietary purine consumption is indicated for patients who habitually eat large amounts of purine-containing foods, of either animal or vegetable origin3,4; however, our results suggest that this type of dietary restriction may be applicable to purines of animal origin but not to purine-rich vegetables.”

    • David Johnson

      I’ve read that high levels of fructose increase uric acid levels although I have no information on fructose from fruit vs. high fructose corn syrup. Cf.
      http://www.wiley.com/WileyCDA/PressRelease/pressReleaseId-105115.html

      Other than cherries, there is evidence that vitamin C (~ 500 mg per day) can lower uric acid levels.

      http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3169708/

      although I read one article that says this is not so if one already has gout.

      Coffee (including decafe) has also been reported by Dr. Choi et al. to lower uric acid levels. Cf.

      http://www.ncbi.nlm.nih.gov/pubmed/17530681

      Different supplements are recommended but personally I don’t trust the ingredients although perhaps there are reliable cherry extract supplements on the market (there’s a limit to how many cherries I can eat!).

      As you likely know there are other factors to consider, e.g. BMI and exercise.

    • Darryl

      Very high fructose and fruit (apple) intake both increase plasma uric acid; a few studies 1, 2 suggest this accounts for the increase in plasma antioxidant capacity with fruit intake. At lower doses, the evidence is more equivocal 3.

      • http://www.eatandbeatcancer.com/ Harriet Sugar Miller

        What are the dangers of high plasma uric acid?

        • Darryl

          Kidney stones and gout. On the other hand uric acid is also the predominant extracellular direct antioxidant, and high levels may be protective in Parkinson’s and Alzheimer’s – some take inositol to raise their uric acid.

    • Jay M

      > I have been vegan over 2 years, and I only eat fruits, veggies, leafy greens, and nuts. How do I lower my uric acid?

      I also following a high-carb, low-fat, low-protein diet based almost exclusively on fruits and veggies and my uric acid is at the low end of the range. If your diet is high in fruits, I would try reducing fats overall (including from nuts) and eat most of your fruits away from your veggies by at least several hours.

      • Diabetesiscured

        I also do high-carb, low-fat, low-protein, between 80/10/10 to 90/5/5. My fat is about 10-20g a day naturally occurring in fruits and veggies. Sometimes I do have a small amount of chia seeds or 1 brazil nut for selenium, but I do not add fats like avocado or nuts. Any nuts and seeds (which is an extremely small amount) would be with my evening salad, not sweet fruits.

      • David Johnson

        >>. try reducing fats overall (including from nuts) and eat most of your fruits away from your veggies by at least several hours.

        I’m a vegan and have an also issue from time to tme with high uric acid (typically high normal at 6.3) and rare gout attacks (so I assume from time to time my uric acid level goes up much higher).

        I’d like to understand the reasoning behind your two suggestions (reduce fats, eat fruit at a different time than veggies). Thanks.

    • DanielFaster

      yes I have had high uric acid levels since going plant based 3 yrs but so far no serious gout that I havent been able to ward off with colchicine.

      • David Johnson

        That’s one approach but for me personally I’d rather restrict fruit high in fructose or sucrose (which breaks down into fructose and galactose).

        I’ve read a recommendation that those with high uric acid should restrict fructose intake from all sources to no more than 25 mg/day. It’s easy to exceed that if you eat a lot of fruit high in fructose (and sucrose). However I have not been able to find a trusted medical reference for the 25 mg/d restriction.

    Good one!!! Thanks, Dr. G.

  • KWD

    Note…typo in the transcript: “…they recorded the largest bowl movements apparently ever documented in a dietary intervention.” Should be “bowel”. Great video, have often wondered if I’m eating too much whole fruit. Look forward to part 2.

    • Mark G

      I eat a lot of fruit daily and sometimes wonder/worry about this too. But whenever I go in for my annual physical my sugar blood levels are normal and my triglycerides are low. So, this is just more good news.

      Thanks for the notification, KWD! We’ll fix

  • Desertsage

    As part of my diet I drink 10 oz of organic pomegranate juice and 10 oz of organic tomato juice, along with 4 servings of fruit. Am I over doing it.

    • Mark G

      Sounds like you’re overdoing the juice, not the fruit, which are two different things. You might want to watch Dr. Greger’s video on it here: http://nutritionfacts.org/video/juicing-removes-more-than-just-fiber/ There’s others you can search for here too.

      I’ve seen more and more articles on the negative impacts of juice vs whole food. Sometimes it provides positives but I’ve never seen anyone talk about what you get from juice that you don’t from the same amount of real fruit (or veggies). The lost fiber takes with it some nutrients and more importantly, it frees the sugar, which is normally bound to the fiber, to rush rapidly into your liver and pancreas. Not a good thing.

      • -A

        The thing is sometimes it is hard for some of us to get in all of the fruit – it can be a lot to eat – particularly for those of us who are underweight and trying to gain (it takes me forever to eat), so juice makes it possible to at least get some of the nutrients, but fruit juice even without added sugars still tend to be high in sugars.

        • MikeOnRaw

          I blend my fruits together making smoothies.

    • Joseph Gonzales R.D.

      Good question. I think it depends on other foods eaten throughout the day. This doesn’t seem dramatically high to me, especially if you feel good while consuming that amount and appear in good health :)

      • Desertsage

        Sorry I forgot to add that my diet is for an indolent tumor, my study says no sugar, but I have been had good results with my course of action on active surveillance for several years now.

        • Joseph Gonzales R.D.

          Best to ask doctor or a dietitian who knows more about your case. I can help you find one if needed? Whole foods are best to obtain the nutrients. Mark G put a link to a video below. Juicing removes the fiber and polyphenols which are both cancer fighters. If you can do more whole foods that is a great start! AICR has a great write-up titled: Does Sugar Feed Tumors?, if interested. Warm wishes let me know how else I can help?

        • dorange

          Would you mind elaborating on your story, Desertsage?

    • Jay M

      Fresh fruits are best. What is the rest of your diet?

  • Panchito

    It would be interesting to see a live debate between Dr, Greger and Dr. Mercola. Dr. Mercola says to only eat 15 grams of fruit max a day and to eat unlimited coconut oil. He seems to have a big crowd of loyal followers.

    • Diabetesiscured

      In my personal experience, I used to eat meat (only organic) and coconut oil as my only oil. I still had severe type 2 diabetes. When I cut out the meat and oil and I increased my fruit, my type 2 diabetes went away very quickly. That is my personal experience. Yes, that would be an interesting debate, I would watch that.

  • AA

    Dr. Greger, I know this is off topic but I wish you would address this issue that I have been reading about in the press recently. Here is a Harvard Health letter on Cholesterol guidelines being changed. Dietary Cholesterol is no longer a problem according to the panel.

    http://www.health.harvard.edu/blog/panel-suggests-stop-warning-about-cholesterol-in-food-201502127713?utm_source=twitter&utm_medium=socialmedia&utm_campaign=021315kr1&utm_content=blog
    In the past, I know you have presented some interesting information on this topic that contradicts the direction that they are going in. I would like to know what your current thinking is on this topic.

    • Joseph Gonzales R.D.

      Hi AA. It’s important to note the new DGFA are not written in stone, and they may change. In the article, “Keep in mind that this isn’t a done deal. The panel, which is formally known as the 2015 Dietary Guidelines Advisory Committee, makes recommendations for the next guidelines update, but these recommendations aren’t always followed.”

      Dr. Greger and Dr. Barnard touch on the cholesterol debate in their testimonies. Dr. Greger testifying at the DGFA meetings? It was just a few days back. This may help. I think he is at 2:06:00 . Another speaker is Dr. Barnard who address the issue at hand. He is probably like 15 min before Dr. Greger. He addresses the AHA/ACC report directly and Dr. Greger follows-up on it. That may help? FYI someone mentioned the timing is before 2:06:00. Try starting the video around 1:50:00.

      • AA

        Joseph Gonzales, thank you for your reply, I can see that Dr. Greger feels strongly about this issue, because he invested the time to do this. Are there any good videos on this site that explain the other side of the argument? I am curious how the pro dietary cholesterol members reached their conclusion.

        • Joseph Gonzales R.D.

          Check out Harvard’s site ( i think they discuss eggs) and other studies in Pubmed. You are happy to share any findings :) I know Dr. Greger talks about the egg and beef industry and you can search website for those videos. One I found on eggs.

    Honey over oatmeal good?

    • thorn324

      Although fruit is sweet and honey is sweet, they are not the same: contrast their fiber and micronutrient profiles to see why. Therefore, it seems (to use your words but with one important one added), “Honey over oatmeal” not “good.”

      • Jen

        What about just adding fruit to the honey and oatmeal, or blackstrap molasses and oatmeal?

        • Jen Drost, PA-C, NF Volunteer

          If you’re going for healthy, blackstrap molasses healthier than honey. Dr. G.’s report of the healthiest sweeteners here:

          • Jen

            Blackstrap molasses is healthier but doesn’t for my taste buds go with some fruits and it gets boring.

          • Jen Drost, PA-C, NF Volunteer

            Jen1, I know what you mean about how blackstrap molasses taste can overpower the fruit a bit. Have you ever gotten to try the #1 natural sweetener? I was very surprised how much I like it. Goes with everything. Where I live, date sugar is expensive, so I usually buy it in bulk online (just a little tip in case you’re interested :) –Jen2

          • Jen

            Date sugar is too expensive but chopped dates go really well in cooked cereal.

          • Jen Drost, PA-C, NF Volunteer

            good choice!

        • thorn324

          Adding sweetener (honey, molasses, sugar) doesn’t seem necessary to me anymore from the standpoint of palatability. (Twenty years ago it seemed necessary–but no longer.) The grain (whether cooked or right-out-of-container rolled oats or cooked steel-cut oats) plus fruit and, occasionally, cinnamon/vanilla extract is my daily breakfast. It’s plain but satisfying. Dr. McDougall would agree!

    • Joseph Gonzales R.D.

      Not sure, olhg1. The best sweeteners (as in most nutritious) contain trace minerals and vitamins/phytonutrients such as date sugar and molasses. However, you are free to choose any type of sweetener you enjoy. The Fruit suggestion is a good one, too.

  • http://www.aboutlowcarbfoods.org/ SandraALCF

    Seems like a no-brainer. Fruit is good for you. If an apple a day keeps the doctor away…

    • Joseph Gonzales R.D.

      Right?! And what about 5 apples a day? Goodbye doctor :) Well, we’d hope. Thanks, SandraALCF

  • Ron Halfhill

    Yeah, tell me all about it !! I have been vegan for 30+ years and eat
    enormous amounts of fruit. I also manage to clog the water closet
    practically every time I have a bowel movement. I’m not exaggerating
    when I say that I hesitate to flush until I am well clear of the bowl
    and have a way out of the bathroom quickly! Whew! But I also frequently
    have more than one bowel movement a day, which I think is more natural
    and thus healthier. Apples, berries, bananas, raisins, strawberries,
    peaches, apricots, papaya (!!), grapefruit, many, many oranges,
    cherries, all the time all year around. Yes, fruit good methinks.

  • Dr.Greger SUPER DOCTOR

    this video was exactly what i needed
    thanks a lots

    by the way is possible that a lots of fruits inflame my wounded knee?

    • Joseph Gonzales R.D.

      If you have an allergic reaction to certain types than maybe. Some folks are sensitive to citrus, apple skins, and bananas. We saw this more so in study participants with pain (migraine headaches or rheumatoid arthritis) Nutrition intervention for migraine: a randomized crossover trial. Not sure you would even know without a fairly drastic elimination diet. If pain is so severe and you suspect certain foods (like fruit) causing this inflammation than it may be wise to consider playing around with diet, but honestly I would say very small chance the fruit is inflaming your knee. Thanks for the good question.

      Best,
      Joseph

      • http://www.eatandbeatcancer.com/ Harriet Sugar Miller

        What about allergies to strawberries? They, too, can cause reactions, right? My psoriasis seems to get worse when I eat them–but maybe that’s my mind messing with my body.

  • Mike Quinoa

    This is extremely good news. Dr. Greger comes up with so many really useful videos. Humans have a natural proclivity for fruit, and being great apes, it only makes sense we should consume a lot of them. I feel healthier just even looking at one of those photos that are jam-packed with an assortment of colorful fruits and veggies.

  • http://cleanfooddirtygirl.com/ Molly Patrick

    I’m so glad you covered this! I’ve always thought it was mad when I hear about people who try not to eat fruit because of the sugar. Happy to have this video to back it up. Thank you.

  • Curious Veg

    Why does John McDougall only recommend 2 servings of fruit per day for weight loss? “Keep fruits to one or two a day. Fruit is largely simple sugar and people can easily eat 10 to 20 servings a day without a guilty thought – after all, fruit is healthy. In truth, fruits should be thought of as healthy desserts, made largely of sugar and water (but with lots of wholesome nutrients).” https://www.drmcdougall.com/misc/2005nl/050100pupushing.htm

    • Joseph Gonzales R.D.

      Good question. The short answer is I am not sure? I know he has a forum, too ;) I am sure other members may know more. Keep in mind Dr. McDougall counsels folks with specific illnesses and has established a specific program. Dr. Greger discusses the latest research that may apply more to the general population. Diet is very personalized. Some folks don’t function well eating tons of fruit. Some folks do! If these studies hold true, more fruit (especially whole fruit) doesn’t seem to be a problem. I think the U.S. has more of a problem under consuming fruit, so I am not worried about portion control. This study is a large randomized trial on 300 obese or diabetic participants. Half were asked to follow a strict low-fat plant-based diet with no portion control or changes (so no restrictions on fruit). A multicenter randomized controlled trial of a plant-based nutrition program to reduce body weight and cardiovascular risk in the corporate setting: the GEICO study. The results were very positive as many participants reduced their body weight and improved blood sugar control. So perhaps looking at the diet as a whole is more important than focusing on “how many servings of fruit per day is good”? From these studies in the video it is shocking how much was really consumed! For more on fruit If Fructose is Bad, What About Fruit? and a Ask the Doctor Q&A: How much fruit is safe to consume?. Hope that helps.

      Thanks!
      Joseph

      • Curious Veg

        Thanks so much for the answer & the links that’s very helpful!

    • Jay M

      I think McDougall’s suggests carbs over fruits partially because rice, potatoes and grains are more practical for most.

    • Jen

      Dr. McDougall is talking to people who need to lose weight and have a difficult time controlling their eating. Fruit is healthy but to pig out on it “eat 10 to 20 servings a day without a guilty thought” will not be as successful in losing that weight.

      And to address why he is strong on starches is they are filling, satisfying and nutritious. Also, provide energy.

  • Greentara

    I have a question. One prominent cardiologist recently posted that drinking smoothies was actually BAD because it separates the fiber from the fructose, and that chewing fruit was necessary to retain the healthy effects on blood sugar etc. because it is necessary to start the digestion in the mouth (I don’t remember all of the details). Do you have a comment on this? I do drink smoothies, because I have trouble eating enough fruit, but don’t want to actually do this if it is unhealthy. Thanks :)

    • Joseph Gonzales R.D.

      It is a common question. I haven’t seen any research to support it. As I dietitian who loves to hear when people feel better from eating a more healthful diet I am less concerned about food preparation, and more concerned with simply eating whole foods. If smoothies help folks obtain nutrients then great. If others want to chew, awesome! Dr. Greger addresses this in his Q&A are green smoothies good for you? And I follow-up to a similar question, here. That may help. Again, great question and thanks for posting!

      Joseph

      • Greentara

        This is a summary of what I saw. I guess the article had to be removed because the discussion got a bit nasty. I would like to point out that I am using whole fruit and green leaves in them, and I am assuming other folks are blending whole fruits. I know that sugar spikes, and the insulin release that follows cause inflammation, which I am trying to avoid. I was under the impression that a smoothie, still being the whole fruit would help with this. Thanks for answering. I really appreciate you taking the time. :-)

        Why I Stopped Drinking Green Smoothies
        Written by Lindsay S. Nixon

        When I was at HTLA, delicious green smoothie in my hand, Dr. T. Colin
        Campbell told me not to drink them. I was crushed, heart-broken!

        Of course I wanted to know why — why shouldn’t I drink them? Aren’t they super healthy?

        Turns out they’re not.

        Dr. Campbell explained it to me very scientifically, and truth be told,
        a lot of it went over my head, but what I did pick up was I needed to
        chew my food and eat it whole — that smoothies, and juices, ruined the
        nutritive properties and it was far better for me to chew my spinach
        then pulverize and drink it.

        I’d heard this all before — from
        Dr. Essy, but after hearing it from both of them, I finally accepted
        what I didn’t want to believe: green smoothies were out.

        Quoting
        Dr. Essy: “Avoid smoothies. The fiber is so finely pureed that its
        helpful properties are destroyed. The sugar is stripped from the fruit,
        bypasses salivary digestion and results in a surge of glucose and the
        accompanying fructose contributes to inflammation and hypertension.”

        Similarly, here are his thoughts on juices: “Do not juice. You lose all
        the fiber and benefits.” With respect to fruit juice, “Drinking fruit
        juice is like pouring the sugar bowl down your throat. It is fine to eat
        the whole fruit. Do not drink the juice.”

        After I succumbed to
        this realization, I called a friend of mine who promotes green smoothies
        as her job, to get her take. Truthfully, I think I was hoping she’d
        tell me the doctors were wrong, and that it was okay to still drink
        them, but I was surprised when she agreed with them whole heartedly. She
        also told me that smoothies are 100 calories more than if I had eaten
        the fruit and greens whole. This I couldn’t believe — HOW is that even
        possible?! but she explained it to me: I’d burn 100 calories chewing the
        food (and then the digestive process of chewed food vs. predigested
        food).

        This got me thinking and I started taking a look at the
        smoothies I’d been drinking. They were all full of healthy, nutritious
        foods — like kale or spinach, mango or apples, dates and water, flax or
        hemp seeds… but they were easily 400 to 800 calories a pop… and I
        could suck them down so fast — I could never physically eat 400 or 800
        calories of whole food like that, and if I did, I’d be stuffed, and
        while smoothies left me feeling full, it wasn’t to the same level as a
        salad. I started to believe what the doctors had told me….

        So
        that’s when I put my blender away and stopped drinking smoothies. At
        first I missed them, but I’ve found that I feel fuller, and more
        energetic if I just eat the greens and bananas whole. I also used to
        have a mild sugar crash if my smoothie was really fruit heavy, and that
        doesn’t happen when I eat the fruit by itself.

        All and all I
        feel like a smoothie once in a while as a treat is probably fine; and I
        do think that if the choice is a green smoothie, or no greens at all,
        it’s better to go for the smoothie, but my plan is to eat my greens and
        fruits whole, whenever possible.

        Note: In addition to Dr.
        Campbell & Dr. Essy, Dr. McDougall, Dr. Klapper, Dr. Sultana, Dr.
        Lederman (FOK), Dr. Goldhammer and Jeff Novick are also in agreement
        here about smoothies. See Natala’s comment below for a very detailed
        explanation (she is a member of the Essy team/E2 Team), as well as links
        to studies and articles. (Thx N!)

        Note: a lot of people have
        asked about soups and hummus; Dr. Essy graciously responded on his
        Facebook page (I’m paraphrasing here) “The main difference is people are
        not drinking hummus and they are not consuming nearly the amount of
        calories at once; with soups, they are eating it slow, with a spoon and
        generally while also eating something else) and soups tend to be
        vegetable-based without fruit (unlike smoothies). Work on eliminating
        liquid calories for juices and smoothies and if you are still concerned,
        work on other things like soups, but smoothies/juices cause the most
        damage, so start there.”

        • http://metalrhino.com/ Scott

          I always try to chew my smoothies as much as possible. At least this will help start the digestion process and can only be a good thing.

        • b00mer

          I think when it comes to smoothies we should approach it with a bit more critical thinking than smoothies = calorie/sugar bombs = bad.

          Lindsey frames her article around such an obviously false dichotomy. She suddenly realizes that her smoothies are 400-800 Calories, so she must stop drinking them. What? What about a smoothie with 4 cups of greens, a cup of fruit, and a couple teaspoons of chia seeds. When I make smoothies that’s what I use and by my calculations it’s about 160 Calories.

          She goes on to reference a 100 Calorie difference in whole fruit vs blended fruit. Is that based on a 100 Calorie smoothie or a 1000 Calorie smoothie? That would be relevant information to know. And even so, for a certain parts of the population, the extra calories may not be a negative. Obviously to anyone trying to lose weight, yes, but for those who are at a desirable weight and even for those who struggle to gain weight or have trouble with large volumes of food (e.g. sick, elderly), this could even be a positive. Frankly, Lindsey sells 1200 Calorie meal plans for adults which she even claims to follow herself (as a relatively tall, active adult) and once wrote a blog entry about an episode of her “binging” on baby carrots. To me this indicates disordered thinking and perhaps her perspective on caloric intake should not be considered sound advice for the general population.

          In regards to Dr. E’s advice, again I think this perspective is again lacking in nuance and critical thinking. Really, works towards eventually limiting even hummus and blended soups? Where is his position on 100 Calorie smoothies? I consume more calories in a serving of hummus than I would in a smoothie. “Soups are eaten with other things”. When I make a smoothie it’s often with breakfast or dinner, so what does that mean? Most importantly, where is the evidence that these smoothies will in fact cause harm? I think reminding people to consume a reasonable number of calories is prudent, and people should be aware of potential issues and monitor their own weight, blood pressure, triglycerides, etc. and obviously adjust their diets accordingly. But putting additional limitations on what most current SAD eaters/potential WFPB eaters already envision as being a very restrictive diet, without solid evidence to back it up could be potentially harmful.

          I’m not saying I’m convinced that smoothies are absolutely good, but general WFPB diet principles are evidence based, while this particular topic seems to be lacking in that area, and is instead based largely on an appeal to authority.

        • Charzie

          Personally, I started using smoothies as a shortcut when learning to eat WFPB, weeks before making any other changes, and they definitely had enormous benefit in my numbers and how I felt! Anecdotes mean nothing I know, but I know plenty of other people who never did more for their SAD diet than add a daily smoothie, and continue to do so because of the results, so I really don’t think they are a negative at all. I used to be diabetic and I will always have to be careful, but even high fruit smoothies don’t spike my glucose, but juices will, so I am either an exception, or they may just be rationalizing.

    • Jay M

      Personally, I get better digestion when fruits are chewed.

      • http://metalrhino.com/ Scott

        Powerful blenders add air into the liquid so that may be one factor in digestion issues with smoothies.

  • Nutritarian

    My wife has always had high triglyceride levels. She was on statins because her resulting cholesterol was too high.

    Since 2011 we have changed to WFPB no/lo SOS diet. Yet my wife’s triglycerides were still too high and her doctor didn’t want to take her off the statins. He said she wouldn’t be able to lower her triglycerides with diet alone but he allowed her to stop taking the statins for 3 months to see what she could do.

    We found the answer on Dr. McDougall’s website. He mentioned that if you’re having difficulty getting your tryglercide levels down you might have to limit your fruit intake.

    My wife has always been a big fruit eater and hated the idea of giving up fruit.

    From the internet I was able to print out for her a list of all fruit by how much fructose each type of fruit contained. She just ate fruit from the bottom of the list, the fruits with the lowest amount of fructose.

    Much to her doctors surprise, her trygliceride levels finally came down.

    • Joseph Gonzales R.D.

      Wow! Great story thanks for sharing this experience. Perhaps this shows everyone varies a bit and anecdotally if triglycerides remain high perhaps lowering fruit intake may help?

      Thanks for you comment.
      Joseph

    • Jen Drost, PA-C, NF Volunteer

      Nutritarian, I agree with the brilliant Joseph :) Other factors that help normalize triglycerides are exercise, getting to a healthy body weight, and avoiding alcohol. Certain foods that you might also already be including (like flax, grapefruit, and amla have also been proven to help lower triglycerides. Hope your wife’s triglycerides stay low! Great to hear about both of your healthy lifestyle choices! :)

    • Victor

      This is for sure right about triglycerides. I experience the same problem. After fruit I have diminished blood flow to my arms and legs. Fruit is not harmless by my experience. And Don Forrester, MD., who volunteers for NF observed this in his cardiac patients at McDougall center.

    Are the benefits stated in the video still gotten through blended fruit such as in smoothies?

      Hi Daniel, I assume so. There doesn’t seem to be anything wrong with smoothies. Dr. Greger addresses this in his Q&A are green smoothies good for you? And I follow-up to a similar question, here.

      Best,
      Joseph

      • MarthaLA

        Except, as I understand it, that smoothies don’t allow for the initial stages of personal processing: chewing, mixing with saliva, the effect of mouth bacteria and or enzymes (I’m fuzzy on that) in preliminary digestion.

        • Joseph Gonzales R.D.

          I thought that too. And it makes sense salivary amylase would not be as effective or utilized without chewing. I guess I am fuzzy as well! I think the most important question to ask: where is the research to support the claims that smoothies are bad? I am not saying never chew again, but maybe smoothies are generating a poor buzz based on science that has not been conducted? Not sure.

          • MarthaLA

            Well, there’s always “If it gets you to consume more greens/fruit” it’s prolly to the good. I’ve seen recommendations to ‘chew’ your smoothies, especially from Katherine Kyle of http://www.greenthickies.com/about/, whose ‘thickies’ incorporate oats. Chewing smoothies boils down to working each mouthful around in there a bit before swallowing, as opposed to pouring them in and swallowing immediately. I ran across her then blog early on. Though with no medical or scientific credentials, she seems well informed, focussed now as a weight-loss expert/coach.

    I sat down at the computer and began to chow down on the delicious chunks of fresh pineapple I had hacked off from its mother ship. Total bliss! And then I found Dr. G’s video on fruit. How apropos is that? :-)

  • do good

    I have to follow a low FODMAP diet because of painful bloating and IBS. Not everyone can tolerate fruit. Also, the video doesn’t emphasise how important fibre is in moderating the sugar content in fruit, which is why whole fruits are preferable to juiced. This film does, however:

    I was a FlexFruitarian for a couple of years, got good and skinny real easy-but had to eat a LOT and every few hours. Flexitarian now.

  • DB Johnson

    The end made me giggle. That too is great for health!

  • Joe Caner

    I found myself eating more whole wheat pasta and bread, and paying for it with poor progress reports from my bathroom scale so I went back to my practice of doing green smoothies for breakfast and vegetables stir steams for dinner and I now am back in fighting trim again.

    There is something wonderfully energizing about pounding down 6 oz of spinach that has been well blended with a variety of seeds, fresh seasonal fruit, a banana. carrot and some ice cubes. I can feel the goodness radiating through my veins as a drink it down.

    I am probably getting more fresh fruits and vegetable for breakfast than most American get all week long. It’s sad really.

  • Dommy

    What happens in one’s body when their diabetes is “cured.” Does the pancreas regenerate itself? Are dormant islets of Langerhans jump-started to put out insulin again? What about the role of the liver? Anyone know??

    • Charzie

      Type 2 diabetics have a functional pancreas, in fact, often it is pumping out large amounts of insulin. The problem isn’t the pancreas, it is too much fat in the cells that won’t allow the insulin to do it’s job. Type ! diabetics are often helped greatly by a plant based diet, but rarely “cured” because they no longer produce insulin.

    I heard that many fruits have a low pH. Is it a good idea to consume it in case of enamel erosion?

  • Dolly

    I’m now at peace knowing that the sugar coming from fruits is not actually bad. For 2 years now, I have embraced a fish, brown rice, vegetables and fruits diet due to CA diagnosis back in late 2012. My rad onco challenged me to take meat, processed sugar and dairy, among others, out of my diet, and double or triple my vegetables and fruits intake. Since it’s more convenient for me to juice or make a smoothie of at least 2 fruits and 1 vegetable in the morning, I do just that. Then, I bring some other fruits to eat in between work. A colleague commented that I am getting too much sugar just the same despite taking processed sugar out of my diet since 2 years ago. After watching this video, I am now at peace. Thanks, Dr. Greger! :-) … And I would like to add that from 130 lbs at the time of diagnosis, my weight went down after about 6 months and has been stable at about 110 lbs.

  • Dick Willi

    I had at chuckle at the end when the discussion turned to a ‘negative’ impact of the consumption of large quantities of fruit and veggies – the largest bowel movements ever recorded! Can I get a witness?

  • Victor

    Can Don Forrester comment on this video and this study? It seems contrary to his experience in the field.

    • 2tsaybow

      Why don’t you ask him? He has a website and there is no need for Dr. Greger to report the results of clinical studies, after he has interacted with other medical professionals to make sure they agree with the results of the study.
      Sometimes a medical professional makes recommendations on the basis of experience and strongly held beliefs, not on the basis of the results of studies.
      Take the question to that doctor. Don’t ask him to come here and argue his point for your clarification.

      • Joseph Gonzales R.D.

        Anyone is free to ask any questions :-)

        • 2tsaybow

          Okay, so do you want me to go to Dr. Forrester’s website and ask him…. No wait! You are the one with the credentials, Joseph, why don’t yo go tell him to come to this site and explain why he is recommending something that this study shows might be wrong.
          I didn’t know he did that, and as I told Victor, sometimes professionals have strongly held beliefs that can stand in the way of a study, But if you have a relationship with Dr. Forrester, instead of taking the question to the doctor then you make Dr. Forrester come here and explain himself.
          I am always open to being ignorant or wrong about any subject and I did say that Dr. Forrester doesn’t have to come hree and explain himself and I did guess he probably wouldn’t. But that’s what Victor wanted. If you can make that happen it would be great.
          I know nothing really.
          We can all ask questions, but we should make sure that the answer addresses the issue as well. In as kind and thoughtful a way as possible, of course
          So make it happen for Victor and me (I guess). That would be really cool!

          • Joseph Gonzales R.D.

            :-) I only meant that Victor is free to ask any question. I’m not sure Dr. Forrester’s experience in the field about fruit. I just know we love when we helps respond to questions on NutritionFacts! Sorry if my comment was misleading. I agree with you that if someone has questions for particular docs the best route is to contact them.

  • http://thelifecake.wordpress.com Kate

    I really want Dr Greger to do a video on calories, I’ve learnt so much over the last year since becoming vegan and I’m fully on the bandwagon with whole foods, fruit etc but the one thing i just can’t seem to find the answer on is ‘how many calories should we be eating’ i have an extremely sedentary job and i rarely exercise I’m 5ft 2 so do i really need 2000 calories a day or am i ok living off 1500 like i am? It is just so confusing, i want to do whats right for my body. If i eat in excess of 2000 why would i gain weight > and if i did then why would i if i am eating whole foods? if anyone has any good video or explanation on if we really need to eat for our height, weight, activity level??? People comment below because it is rather frustrating when people say you need less if your less active or less if your small and then someone tells you the opposite

  • Lauren

    Huh. My mother in law had horrible blood test results so her doc sent her to the Diet of Hope weight loss clinic where they told her to cut all fruit out of her diet. Is this clinic behind the times or might there be another health reason for cutting fruit?

  • Lee Fisher

    Twenty servings of fruit a day is healthy for you? OMG. I think ‘Freelee the Banana Girl’ is the poster child for this study. She does eat a lot and a good variety of fruit on most days when she’s not eating 50 bananas to prove the point that fructose from whole fruits is not bad for you. More fruit should mean less sodium consumed and a more balanced electrolyte profile from one’s diet, so that seems to be an important aspect of it, too for heart health. I suspect it also helps those with fluid retention issues, and may be a factor was to why the people in the study are losing weight, waist circumference, etc., when they eat 20 servings of fruit a day..?

  • lyne

    My nutritionist Anne-Marie told me not to eat more than 3 fruits a day, because of the risk of having «yeast infection» or «mushrooms» (I hopeI have the right word because I’m a French person… sorry if not but I hope you understand what I say)…

  • Adam Hefner

    So how is the amount of fructose measured say by per gram of a certain fruit? So if you chose a banana, If your banana (unpeeled) weighed 100 grams, how do you equate that into the amount of fructose in it?

  • erika

    Dr. Greger, I watched your video ( https://www.youtube.com/watch?v=nU_RkeA88DY ) and was wondering if the same results happen for refined white table sugar and sugars like unrefined organic coconut sugar. I’m wondering because 1-2 times a day I drink a hot carob drink with 1 tablespoon unrefined organic coconut sugar, water, and cashew milk. Would a drink like this without berries, have a negative effect on my blood sugar even though I use unrefined organic sugar?

  • Viv

    “The nutritional problems come when the fructose….are added to foods” Does this mean I might be in trouble when I drink only smoothies (always combined a lot of fruits + green leaves) from 8am-6pm? as I see green leaves as ‘food’ ;-)
    Also someone warned me that due to these fruitgreens smoothies, they cause fermentation and liver damage. Do I need to worry?

    • shaneq

      Why would this cause fermentation, because you are combining fruits with the greens? Would fermentation not be an issue if you were eating them separately?

      • Viv

        @Shaneq, I have no clue, I’ve been warned by several people but when I asked them why, they couldn’t explain, only told me that it is a common situation with a high fruit intake.
        Actually now that I read my post, these are 2 separate questions. The first one is a question as a response to the video. The second one (“also…….”) is separte one and should be: can a high fruit intake cause any liver damage due to fermentation

  • Steve

    How much is a “serving” of fruit or vegetable?

  • zm4jk0

    Fruit as a whole food is the best food for people. Since i’ve learned to eat fruit meals at least twice a day i feel better and better. I add 1 meal of veggies every evening. Now i just need to learn how to avoid stress.

  • Ray Tajoma

    Natural (none Genetically Modified) RAW Fruits, vegetables and nuts. As soon as the PHD lab technicians (secretly) attack genes of fruits and contaminate our fruits and vegetables (in 10 years or so), Raw Vegans will also get fat and die of cancer stroke and heart attack just like the rest of population if not at higher rates. Enjoy your natural, organic, raw fruits and vegetables while it lasts in this short historical time period, before it is stolen from us by FDA and other evil monsters.

    “the nutritional problems of fructose-and of table sugar, which is another form of sugar called sucrose…” is there research about how lactose fits into to these ideas?

  • jamfhall1

    People also do not like to spend so much time in the bathroom. That’s another reason why they do not eat fruits and vegetables. Yes, I’ve heard people say that.

    • thorn324

      This makes no sense. The only reason people spend “so much time in the bathroom” is because their fiber-depleted diets make the passing of feces a slow, difficult, and often painful process. Those who eat a high-fiber diet & drink enough fluid spend little time in the bathroom (in & out quickly–in more ways than one), and it’s likely their total time for defecation is (far) less for 2 to 3 times per day than for 1 the slow/difficult/painful visit once a day of those consuming a fiber-poor diet. Recommended: John McDougall’s book _Dr. McDougall’s Digestive Tune-Up._

  • Bob413

    If your trying to lose weight, any fruit is too much. If your otherwise healthy and active; just enough fruit to keep you fueled and to satisfy your sweet tooth will do.

    Some fruit comes with a host of benefits like anti-oxidant properties (like berries), while other fruits don’t really offer anything ideal (tropical fruits). Sugar is sugar though, so if your sensitive to it and over weight, you shouldn’t eat it.

  • Jupiter

    I eat a lot of whole fruit, 20 bananas a day. I have read that as long as the fruit is not separated from it’s fiber and eaten in whole form it does not cause blood sugar problems. I keep getting warned by anti-sugar people that fructose is bad for the liver and causes fatty liver. Again is this only for refined fructose and not fructose with the fiber intact? I would really like to put this one to bed once and for all thanks.
    Are there any medical studies on liver fuction from consuming natural whole fruit?

    • Charzie

      I’m no expert, but I think for the majority of healthy people, eating whole fruit is a positive, and it is not the same as added, manufactured fructose, as the video states. I think however, older people or people who already have medical issues may have to still experiment with how well they tolerate larger amounts of fruit. We are all human, but with different circumstances.

  • Chris andaur

    Hello,

    The effects of apricot kernels and its anti cancer properties has been documented….but what about other seeds? Cherry, apple, peach etc.

    doing a generic Google search, some pages claim that consuming seeds is toxic and harmful.

    The bible mentions in various versus to eat the fruit and seed. Any insight or information would be awesome. Thank you for your time!!!

    Chris

    • Joseph Gonzales R.D.

      I would take serious caution here regarding apricot pits. An accidental swallow of an apple seed is not the same as cooking-up apricot pits (or however they are used). Just don’t think the science is there and I see more reviews on toxicity then benefits. This is old but relevant review discussing the lack evidence for vitamin B17. From my understanding folks tout apricot pits for their B17 content, but this is not factual or scientific from what I gather. Perhaps a better citation, here, as a site user pointed out a while back. Hope this helps. Thanks for reposting your question.

  • Princess Thomas

    YaYY! Im so happy, I thought my fruit smoothies on top of my juicing greens were bad for me. I am more than happy that I can have more than one smoothie

    • Arto Beck

      That’s not recommended as a smoothie has separated the fiber from the fructose BEFORE it gets into your digestive system. The fiber, as stated in this video, is what minimizes the effects of fructose.

      Always better to eat high fructose fruits rather than juice them. And only eat a lot if you ALSO eat 2x the vegetables as this video shows.

  • maca

    For some fruits, I buy frozen, but organic, at my health food store. I wonder if there is added sugar if you buy fruit frozen in bags and if you consider it nutritious. Sometimes I read that Dr. Greger uses frozen fruits in some of his recipes, like his pink drink. Thank you!

    • Rami Najjar

      If you read the ingredients, and there is no mention of anything other than fruit, then it will not have nay added sugars.

  • Sarah R

    Hmmmmm . . . Obviously a whole food plant based diet wins once again :D I still can’t help wondering if the 100+ grams of fructose per day consumed on a high fruit high raw diet is healthy in the long term though since fructose is processed by the liver and involves different hormonal signaling than glucose.

  • Joy Schwabach

    I’m so glad to hear this. A different vegan doctor on the web was saying that those with high cholesterol should have much less than three fruits a day. But do you think everyone’s different? Why is it that some people go on low carb diets and see their cholesterol drop? I know this is foolish if they do it with animal products, since they dramatically increase their chance of heart disease and cancer.

  • baggman744

    What does he mean, “Given the 44 servings of vegetables”? Is that per day? Can’t be.

  • vlp

    Can anyone tell me if the anti-cancer or anti-oxidant properties of blueberries are lost from freezing or cooking? Thank you!

  • Arto Beck

    I’m seeing conflicting information here that does NOT support what the Dr. is saying. Put aside that the first “no amount of fruit is too much” study referenced (briefly) was from 1971… I’m sure there is something newer that relates to our current state of nutrition. And then the Dr. mentions the Jenkins study of 2001.

    But how does the Jenkins study prove anything about increased fruit servings? If you read the study’s title in the background (High fiber vegetable, fruit and nut diet) the only solid conclusion you can come to is that there are no bad effects from extremely large doses of a “high-fiber vegetable, fruit and nut” diet.

    Why does no one question the fact that the vegetable servings were 10x the normal and 2x the amount of fruits? First, how many people do you know who eat more than 6lbs/4kg of vegetables? Try none. In what scientific world is that a controlled experiment? How can you establish the fruit’s impact apart from the vegetables and nuts, the vegetables from the fruits and nuts, etc.? There are three variables that could be affecting/not-affecting the results and yet the narrator unscientifically uses the study to claim that 20 servings of fruits (234g/day fructose) has no adverse effect.

    Another point I’m struggling with is that fructose toxicity is initially stated as a fact and then having it magically disappear even at 4x this toxicity level inside of fructose fruits. How does a molecule lose that acute toxicity? Is there a fructose antidote in the fiber? Again why does no one question this miracle?

    The obvious story here and worth a rigorous scientific experiment is that high amounts of VEGETABLES can do amazing things besides large bowel movements … like counteracting what should be high fructose toxicity.

  • Vectraat

    Based on some research…

    Fructose Toxicity…

    At high intakes fructose can be quite harmful. Here’s a brief list.

    • In the gut, fructose promotes gut permeability and poisoning of the body by endotoxemia.

    • In the liver, fructose promotes fatty liver disease and metabolic syndrome.

    • Fructose disposal generates uric acid, which can cause gout or kidney stones.

    “High fructose intake therefore leads to an accumulation of uric acid crystals in the joints, causing intense pain, a condition called gout. People with impaired fructose metabolism get gout at a high rate. Fructose, by way of uric acid, may be a major cause of kidney disease.”

    http://www.ncbi.nlm.nih.gov/pubmed/18258933?dopt=AbstractPlus
    http://www.ncbi.nlm.nih.gov/pubmed/2236043?dopt=AbstractPlus
    http://www.ncbi.nlm.nih.gov/pubmed/17921363?dopt=AbstractPlus

    • If the liver can’t dispose of fructose quickly enough and the blood level becomes elevated, it promotes cancer.

    http://www.ncbi.nlm.nih.gov/pubmed/20647326?dopt=AbstractPlus

    • High doses of fructose clearly promote obesity in clinical trials and in animal studies.

    Given the known dangers of high fructose consumption, it seems prudent to minimize fructose intake.

    Uh, there was a lot more I could have posted, but I doubt anyone is going to read it anyhow.

  • Flynn Perkins-Best

    I ate a high carb, low fat diet that included 20 portions of fruit a day for over a year. I stopped when I got a xanthelsma on my eye which is a permanent and unsightly cholesterol deposit. After much research I deduced I had pre-existing low thyroid function and it was February so not much sunlight, cholesterol is a precursor to vitamin D right? I guess I also added coconut sugar to smoothies (Jeepers, what was I thinking?!). I’m now low fruit, paleo vegan (nuts, beans etc, but no/little grain). I have pre-ordered the book and hope to find the answers on the best diet in there… hopefully I won’t die whilst I’m waiting! But I’m actually not feeling great, so I’m looking forward to making some changes to my current diet!!

    I recently encountered an unusual case. A person in his 20s who is eating ONLY fruits since he was 15 years old. Every several weeks he eats only ONE kind of fruit. He is spending most of his time in front of the computer searching and reading about nutrition. He is currently in relationship, sustains himself, is not neglected but is very thin. I was wondering is he suffers from an eating disorder (I encountered the term orthorexia)? How does this extreme diet affects is health? For instance, it is known that B12 deficiency can cause severe mental disorders. What about other deficiencies? What is the risk that this fruitarian diet pose? Noam Drigues, MD (Psychiatrist)
