    Please feel free to post any ask-the-doctor type questions here in the comments section and I’d be happy to try to answer them. Be sure to check out Inflammatory remarks about arachidonic acid. Also, there are 1,449 subjects covered in my other videos–please feel free to explore them!

  • Toxins

    This is super informative. Thanks! I like how you clearly stated that our body makes the cholesterol we need as well as the arachadonic acid based on our evolutionary origins as primarily herbivores.

    • Toxins,
      I’m a bit confused about that chart. Do chickens and eggs top the list because Americans eat more of them than, say, turkey? Does turkey have as much arachidonic acid as chicken?

    • Hi, again, Toxins,
      Any chance you or someone else could answer my question below?

    • Read 80/10/10 I think humans evolved as Frugivore’s not herbivores

  • Turkishshepherd

    Great video!!! Although plant-eating apes?? Really??

    Why is there so much cholesterol in breast milk if we can make our own? Why does my baby need it and I don’t?

    • Linda

      Kid’s brains grow until they are about 4. The brain is mainly made of fat.

  • DrDons

    In looking at some studies on the ingredients in human breast milk I couldn’t find cholesterol listed. Human breast milk does have triglycerides, carbohydrates and many other ingredients including antioxidants see: Your baby’s liver and other tissues make all the cholesterol s/he needs.

  • DrDons

    Thanks Toxins. I should have checked with the USDA. Nice to know that breast milk has cholesterol. So the answer to Bechochic is I don’t know if babies need it or not but breast milk remains the overwhelming best food for newborns.

    • LynnCS

      As I understand it, we all need cholesterol. I think we make the right kind and the right amount. Certainly not in the form of bread and butter and steak and gravy.

      Babies are not good nutrition examples to use for adults. Babies are growing and require different proportions of nutrients. In addition, it is unlikely that the infant’s digestive trac (including the micro-biom) is fully developed – so they digest things differently.

      Even premature babies require different nutrients than a full term baby – but the mom’s body automatically adjusts the nutrients in the breast milk to accommodate the needs of the premature infant.

      Another example is cows: No adult cow drinks cow’s milk. A new born calf needs the milk – an adult does not and, in fact needs other things that are not present in the milk.

      Yes, breast milk is preferred for infants for MANY different reasons but: Using infant nutrition needs to project adult needs is not a viable method.

    is 1/2 cup of legumes a safe amount to eat daily ?i eat a low fat vegan diet as per dr mcdougall.

    • Toxins

      It is indeed safe, in fact, it is extremely beneficial. The consumption of legumes (beans, peas, lentils) was associated with lower systemic inflammation in women (

      An entire cup of black beans only has 1 gram of fat, I see no reason to avoid this highly nutritious bean.

    • Roberta

      Beans so are a common denominator for long life among various peoples. About a cup of beans daily is suggested by Vegan Dr. Joel Furhman.

  • BarbaraH

    As for the cholesterol in breast milk, this might be a helpful explanation:

    From :

    By the way, human breast milk (which is, strictly speaking, an animal product) does contain cholesterol (yup, even a vegan mom’s – because mom’s body creates it, and some is naturally present in milk). This is, of course, fine because mother’s milk is the perfect food for babies. But if medical experts and formula manufacturers thought that dietary cholesterol was so important for brain development, they would put cholesterol in infant formula. They don’t.

    • Toxins

      That is an excellent point Barbara. Thanks!

      • BarbaraH

        Just to be clear, that’s Dina Aronson, M.S. R.D, who wrote that paragraph. I copied it out of the link I gave.

  • GlenWise

     Very interesting video. As an asthmatic who’s condition is well controlled with theophylline 200 mg tabs, Proair, and Symbicort; it’s important for me to be knowledgeable about what I put into my body. Unfortunately, I recently failed to do some research before embarking on a bodybuilding regimen. I began using several supplements like L-arginine, a Nitric oxide booster, and a post-exercise tablet along with perhaps the worst possible form of protein. I started purchasing cheap, farm raised tilapia from the largest retailer in the world. Needless to say, this was due to economical reasons. To make matters worse, I was without my corticosteroid inhaler Symbicort for approximately one month. I believe all of these factors lead to some significant inflammation in the lungs along with scattered prehypertensive bP readings. I went to the doctor and was given a corticosteroid injection and some samples of Advair to get me by until I could return on Symbicort. I have been back now on Symbicort for about ten days now and I’m doing better day by day. Needless to say, this has been a hard lesson to learn, but a lesson none the less. I’ve said all this because the more I learn about bodybuilding nutrition, the more detrimental it appears to be for those with medical conditions like asthma, allergies, various heart conditions, and arthritis. I hope I’m wrong. Assuming bodybuilding can be done in a healthy and safe way for those just mentioned; it just leads to many more questions. Let’s begin by looking at the main food sources for the vary building blocks for muscles themselves. The “big three” are fish, chicken, and eggs. The concern here is that they all contain arachidonic acid which is the culprit for inflammation. Obviously how this process affects individuals is as unique as the individuals themselves. It’s not a secret that this acid is hard to avoid for those in this sport, because of the vary foods which contain it. The “Million Dollar” question is: how is the body going to respond to such large quantities of this chemical that a sport such as bodybuilding demands? This is perhaps the greatest hurdle for those aspiring this sport with pre existing conditions. So, for someone with asthma, what’s the healthiest, safest, and most economical form of wild fish? Is 100% egg whites safe for asthmatics? And if not, what other sources of protein are? Is there a limit Before an inflammatory response occurs? Again, I hope I’m wrong for sounding so pessimistic, because afterall, I would like to “step-up” my exercise routine in order to reach my genetic potential. I’m just not willing to jeopardize my health to do it.

    • LynnCS

      There are a lot of stories of people overcoming Asthma buy going on raw fruits/vegis/lots of greens. Juicing, smoothies, and salads. Check out Youtube.

    • I would add dairy to your list to be avoided as an asthmatic…. see as a start the videos on dairy especially see… You might also enjoy the video… and the others listed under the asthma topic. I wouldn’t worry about protein intake see the three newsletter articles in Dr. John McDougall’s monthly newsletters… History of Protein(12/03), Protein Overload(1/04) and Sources of Protein(4/07). You might be interested in comparing the essential amino acid profile of eggs, broccoli and asparagus. Evidence suggests you should minimize protein for long term health. As a body builder you might enjoy videos and material by Robert Cheeke who is a plant based body builder. There are no “safe” fish only fish that have less chemicals… as they all come with cholesterol and saturated fat. The Omega 3’s in the fish are from the algae the fish eat. No reason to eat fish if you want to eat a healthy diet. Good luck.

    • Sona

      FYI, my daughters asthma disappeared magically once we eliminated eggs and milk from her diet.

  • Is it better to raise your own chickens for the eggs ? Or is this just as bad as store bought eggs?

    • Toxins

      Eggs have inherent substances in them that are simply unavoidable whether they are store bought, organic or raised in your back yard. Eggs in general are a harmful food and one should avoid eating this food.

  • Michael Greger M.D.

    For some context, please check out my associated blog post Inflammation, Diet, and “Vitamin S”!

  • Toxins

    Why is it that chickens are also the number 2 contributor of Omega 3?

  • Mike F

    Are the negative effects (i.e inflammation due to omega-6 consumption) of eggs strictly quarantined to the yolk? I eat egg whites fairly heavily so was curious if I should change my dietary habits. Thank you for the study results.

  • Stretch

    What about the gels that are being injected into knees that come from rooster feathers? Should that be helpful or harmful for arthritis?
    I believe it is called gel one by Zimme corp. can someone help with this? Thanks, stretch

  • kunal

    hey, I am kunal from india.

    doctor suggested not to go for nonveg due to infection problem..

    what is the best way for getting rid of iron deficiency. ?

  • Kelly Johnson

    Man I am finding out every food I find worth eating is bad for me. As a woman of only 85lbs at 5’4 eggs were one of the things I use to help gain weight and ENJOY the food. Most everything I eat now I just tolerate. I don’t enjoy it much. I am not a fan of veggie and beans no matter how they are prepared. This makes me sad that I might have to get rid of eggs to

  • Ashley

    Is this the same with duck eggs or any other bird egg?

  • oliver

    I disagree with your cholesterol analogy. Cholesterol is very important and eating cholesterol is NOT a cause of high cholesterol since the body simply makes less. The problem is eating high saturated fats and salt, these cause the body to produce more cholesterol. Eggs are one of the best foods around, be cautious about telling people not to eat them. I feel you should also mention there is good and bad cholesterol, and that it’s the ratio of one to the other which is important, not dietary cholesterol. If eggs -even organic- are contaminated, I accept the advice, but not on the simple fact of their cholesterol content. The only people advised to avoid/limit eggs, are those with disorders/pre existing cholesterol problems.

    • Toxins

      The national academy of science disagrees with your view on cholesterol

      More information can be shared regarding eggs if you wish.

    • Sam Noah

      You’re 100% correct on the cholestrol and the eggs thing. and I honestly couldn’t care less what the USDA or National Academy of Science say, countless other entities and studies in the US and Europe recommend otherwise. The USDA and NAS both recommend grains and breads (whole grains) that are loaded with gluten; which is a harmful protein whether or not you’re allergic. Should we start counting the inflamatory properties of grains and legumes or their destructive impact on the digestive system? or should we talk about the hormonal inbalances soy creates. All foods have their good and bad properties, but we can’t just minimize the good and maximize the bad and vice versa to justify our eating choices and we also can’t discard an entire food category because of the downs and be missing out on the ups. Do the cost benefit math. Also while I’m at it, all those rules and studies don’t apply to every one, each human machine processes different foods in different ways. It’s each person’s responsibility to find a deitary system that works for them.

      • Blaice

        I know this is a super old response, but I like how neither of you provide any scientific data to back up your (scientifically flawed) claims, beside the moderator who attempted to help alleviate the confusion. Saying exogenous cholesterol and arachodonic acid are healthy, does not make it true. I’m sorry. Cognitive Dissonance is certainly real though.

  • Kayron

    Why is it that I eat 3 eggs (organic free range) a day at least 4 days a week and my good cholesterol is way off the charts and my bad cholesterol is way below the lowest in the range? My doctor actually was taking notes on my diet to replicate it

    thanks for censoring, you qualify yourself very good

    • Tommasina

      Andrea, can I ask what you’re referring to regarding censoring?

      • Andrea Deledda

        i posted it because didn’t find my previous comment, I’m sorry

        • Tommasina

          Oh, okay. That’s the comment you were looking for above then? Sometimes comments with photos or links get stuck in the spam filter. The only time we might delete a comment is when it’s an ad hominem attack on another user, but that hasn’t happened much in my time here.

          • Andrea Deledda

            ok, i apologize again, bye :)

  • What should you do if you are low in arachidonic acid, like if you’re an alcoholic or have diabetes, anxiety, ADHD, depression, eczema, autism, Alzheimer’s, or schizophrenia, all of whom have found to be low in arachidonic acid? Or, if you don’t have the delta 6 desaturase enzyme to make arachidonic acid out of linoleic acid, like people with Celtic, Scandinavian and Naive American ancestry? Would you have to eat meat?

  • Bud Kelly

    Sorry, Dr. Greger but there is no such word as “pussy” because there is no way to spell it. I think you meant purulent. ;-)

  • Bo

    You have to look for high content of dha,epa and dpa and low in. aa så so Fish is excellent. Eggs, poultry, meat and organ meat are bad.
