    let’s hope the pill people don’t try to squeeze this into a bottle. You would have thought they’d have learned their lesson after (most) all the other vitamin and supplement fiascoes.

    Hey Dr.Broccoli! Very interesting. I learn something new everyday by watching your videos. thank you

    • Dylan

      Dr. Broccoli! That’s a good one Mary! Very well suited.

    yay for “skin of cucumbers”…I *always* include skin of cucumber (organic as much as possible to avoid the wax on conventional cukes) in my salads or as a hummus dipper! thanks Doc AGAIN for your life-saving work here! All respect and love to you! ♥ !

    Can I keep munching on leucine rich almonds ?

    So, what are the leading preventable causes of death for people who eat whole food plant based diets? They live longer, but I’m curious as to what does eventually cause death among them?

    • Auntie M

      I read that they suffer much less long-term illness and more often die of catastrophic injury or illnesses such as influenza, pneumonia, etc.

      • Plantstrongdoc M.D.

        That people who eat whole food plant based diets should die more often from influenza and pneumonia makes no sense. People who die from influenza and pneumonia typically have a chronic condition such as heart disease, diabetes, rheumatic disease, which a WFPD prevents, and a WFPD is typically lower in calories (and maybe have CR mimetic properties), which probably reduce the decline in immunefunction as you age.

        • Han

          You appear to be missing the context. People die of something eventually. What do vegans die of?

  • EdK

    Unlike methionine, plant proteins in general and animal proteins in general do not differ all that much in % leucine content. For example, as far as leucine as % of total protein goes, egg protein has 8.5%, milk protein 9.7%,and beef protein 7.9%, while soy protein has 7.6%, pumpkin seeds about 8.4%, and rice protein 8.3% (I did some calculations using the tables in Bowes & Church). I know Dr. Greger wants to push the plant based diet, but eating plant based protein will profide about the same amount of leucine as eating he same amount of animal based protein. It looks to me that if one wants to reduce leucine intake, one would need to eat less protein, period.

    • b00mer

      …and an effective way to do that would be to eat plant-based.

      1 cup rice with chicken breast: 500 Cal, 58 g protein, 4.4 g leucine
      1 cup rice with 1 cup beans: 460 Cal, 19 g protein, 1.6 g leucine

      Unless people on a non-vegan diet restrict their food intake overall, or are in fact limiting their meat consumption (i.e. making their diet closer to a plant-based one), they will most likely consume excessive amounts of protein and subsequently of leucine. An advertisement for a plant-based diet in the context of this subject appears quite reasonable to me.

    I am wondering about something mentioned in this video. I had anorexia nervosa for many years in my 30′s (I am now in my 40′s and still have struggles)-I guess that may offer me some protection (which would be the only good thing that came from that illness). Now that I am trying to fully recover, I am being encouraged to eat low fat dairy yougurt–it seems like this is not a good thing based on the video. I normally mix it with fruit and hemp seeds–what should I be doing instead. I apologize for my ignorance as I am new to all of this.

    • Jessy R.D.

      Maybe try mixing those good items in soy yogurt?

    • b00mer

      Hi gigi, could you share why you were being encouraged to consume yogurt? If it’s an issue of calcium, you can easily get more than enough calcium from plant foods, particularly beans and green vegetables, and even seemingly “low” calcium plant foods like fruits, whole grains, etc all add up over the course of the day. Add in a serving or two of fortified non-dairy milks, tofu, etc, and your levels will quickly skyrocket above the recommended intake. If the idea of supplements bothers you, keep in mind the calcium in most dairy products comes from a supplement given to the cows in their feed.

      If it’s a matter of protein, know that it’s mathematically impossible to consume less than your rda for protein on a whole foods plant based diet, provided your caloric intake is sufficient. On my simple diet of vegetables, fruits, whole grains, and legumes, I consistently consume no less than 150% of the recommended amount for my weight.

      Of course if you enjoy your yogurt habit, you can very easily switch to any non-dairy yogurt. If you find it cost prohibitive (it’s quite expensive where I live), you can make your own for much less, either with a cheap yogurt maker (~$20), a crockpot, or a pressure cooker.

    • William Dwyer

      You don’t need dairy for the calcium, if that’s why your eating the yogurt, but I would make sure to include kale every day as one of your vegetables, as it has a good amount of absorbable calcium as well as vitamin K. You could also take a calcium supplement, but you don’t really need more than about 800 mg of calcium per day; the body can’t absorb more than about 500 mg at a time anyway. You should also get at least half as much magnesium as calcium.

      With anorexia nervosa, you have to worry about osteoporosis, caused by lack of estrogen from amenorrhea due to low body fat (less than 16%), and also by insufficient weight bearing on your bones. So make sure to get enough weight bearing exercise as well as enough vitamin D and vitamin K.

      You also need to keep your diet sufficiently alkaline by including plenty of fruits and vegetables and enough protein (from beans and grains) to help rebuild and maintain bone density. If necessary, I would also include a potassium bicarbonate supplement (“Potassium Basics” which can be purchased online) to ensure that your urinary pH remains at 7 or higher. Otherwise, your body will take calcium from your bones to raise the pH. You can purchase pH test strips online to determine your urinary pH. If it’s lower than 7 to 7.25, I would take the potassium bicarbonate to raise it

      In order to ensure that you get enough calories, you could also include high calorie foods like avocados and nuts.

      Hope this helps.

      gigi: re: “…it seems like this is not a good thing based on the video.” I agree. In fact there are a large number of videos on this site which indicate that dairy is not a good thing.

      I think b00mer was right on when she said that you would want to find out *why* they recommended yogurt. That will help you figure out a more healthy alternative.

      I am not an expert, so I have no idea why they would have made that recommendation. But in addition to what b00mer suggested, I was thinking that maybe they were looking for food that would have a high calorie density. In that case, you could try to figure out the calorie density of the yogurt you eat and find comparable whole plant foods to eat instead. Just an idea.

      If you find out the “why”, let us know and we maybe this group can make some helpful, specific suggestions.

      I know how overwhelming good nutrition can seem at first. I can promise that it does get easier over time as you absorb the information and learn what does and does not work for you in terms of taste, convenience, etc. Good luck to you.

  • Rod Stevenson

    Question for Dr. Greger. This video and many others note the importance of the cancer fighting abilities of cruciferous vegetables as well as tea (no doubt Matcha and Hibiscus are at the top of the list). However a simple Google search of “pesticide + tea” brings up many concerning and properly sourced news feeds, of all things, the carcinogenic properties of pesticides still on the packaged tea. not to mention if we simply steep the tea or ingesting it whole as per your practice at home). Is there enough data out there to provide the context if this is a real threat? Does the tea cancel out the negative health effect of the pesticides? Those products claiming to be organic tea at a premium price; do we get our money’s worth? For those of us who consume the tea whole (as you mentioned is a common practice with your family), should we be more worried ingesting more of the less water soluble pesticides with the whole tea?

  • Andy

    My question is… if we have cholesterol screening available to give us information about our heart health why don’t we have any tests for our cancer health?
    Many of the videos discuss dropping blood on cancer cells and seeing them either multiply or die.
    Why aren’t there tests that people could get that would tell them… we dropped your blood on some liver cancer cells (or breast or prostate etc…) and they grew or they died so things look ok.
    If things don’t look good then they can suggest dietary changes and test again? Why are we not using this? Is it due to cost?

    • b00mer

      Hi Andy, yes in vitro work is incredibly expensive, and as someone with experience in mamallian cell culture I personally would not want this to become widespread practice. The time and expertise/training, cell lines themselves, growth media, sera, enzymatic and other solutions for processing cells and all the plastic bottles they come in, all the single-use disposable plastic pipets, flasks, slides, vials, gloves, booties, the maintenance of labs and all the equipment within, etc, that are necessary to do one simple assay are perhaps justified in performing representative and informative studies, but I think it would be quite wasteful to perform as testing for individuals. I think the public would be much better served by advocacy that exposes them to the information we already have. Combined with all the other in vitro work, as well as epidemiological, clinical and interventional research that has already been done, we have quite a consensus already as far as which foods cure and which foods cause cancer. Just my two cents.

      Another thing to keep in mind, as many people who eat a plant based diet either come to it through ethical reasons, or come to care about the ethics of animal consumption as a result of dietary changes – in vitro mammalian cell culture nearly always uses fetal bovine serum. And yes, it is as awful as it sounds. Though synthetic sera have come on the market and are objectively superior in terms of consistency of composition and sterility, in the scientific world, changes in methodology come slowly.
