  1. Bakers yeast isn’t nutritional yeast right??? Nutritional yeast is supposed to be inactive….Anyone here feel strange when consuming nutritional yeast?. Trying to figure if it’s ok or not for me.. Maybe it’s even the amount used? The taste is defin addictive lol! Maybe too much neuro-excitatory….?

  2. I have/had Crohn's (no major symptoms in 20 years) and tested very high for food sensitivity to Bakers/Brewers/Nutritional Yeasts. I have actually been getting better scores on that through the years (3 tests over that period from an off the charts 4+ to now just a level 1 reaction). Am wondering if things like pickles, kimchi, sake, wine, vinegars, miso, and other ferments should to be avoided as well? Help, Dr Greger!

  3. This video is worthless and worse misleading and not understandable. The title is misleading as well. What I want to see is not a bunch of papers being highlighted and read from. I want to see a video about why or why not I should consume nutritional yeast especially on my popcorn which I love.

  4. hi guys need help, would it also have negative effect if the selenium supplement that I am taking is derived from yeast? and I have an Grave's.

  5. I'm not yet sold on the 100% plant based idea, but I'm addicted to Dr. Gregor's videos. So well put together, and never fail to make me laugh. Love this guy!

  6. This would be a great video except for the non distinction between nutritional yeast (which is inactive…ie, non expanding) and the other 'active' yeasts. I do not have crohn's, yet my body does not react well to active yeasts, even in gluten free breads…yet, I can tolerate small amounts of nutritional yeast daily, with no edema…no extreme bloating etc. Do you consider the processing of nutritional yeast to distinguish it somewhat from brewer's, etc? Having said that, even inactive yeast is best consumed in small amounts, if at all.

  7. So should we all just not use nutritional yeast in case it gives us Crohn's disease , even if it mite not be the only thing that can trigger it , perhaps nutritional yeast is just not worth the risk

  8. Happily, I don't seem to be susceptible so I see no reason why I shouldn't continue to make my vegan recipes which use nutritional yeast. Color me RELIEVED.

  9. Mycotoxins and aflatoxins in Beans, Corn, Coffee, Nuts, especially PEANUTS, apple cider vinegar, mushrooms, grains and dried dates, prunes and raisins would make a great video. Also mold poisoning and detoxing of the cytoxins that cause CIRS chronic inflammatory response syndrome.

  10. Wait so I should stop Nutritional Yeast? I thought Nutritional Yeast was inactive. I don't have Crohn's disease but I think my immune system is weak.

  11. I’m confused because all of these studies he sighted said bakers yeast and he’s saying not to eat nutritional yeast, but they aren’t the same thing.

  12. Recently I kept getting really bad migraines where I could barely function or think straight. Then realized it was always right after I ate a plant based "chzz sauce" I made with nutritional yeast. So I started doing research. Others have the same symptoms as me. Sad though I really liked it. But it is not worth it.

  13. There are at least 2 different types of yeast. Natural yeast (live bacteria) and chemical yeast. The 2nd one is not very good for health. The studies discussed do not mention what type of yeast was tested.

  14. B vitamins are also listed, so that means -you know what I'm gonna say next! – No vit B12 supplement? They also switched people to soy milk – which is normally fortified with b12

  15. Reg the gloves: maybe that hand in the picture wasn't a doctor's hand, but the patient's or some of the patient's relative's hand showing the fistula to the camera. Doc probably had his hands full with operating the camera. Or the pic might have not even been taken in the doctor's office at all but at home by the patient himself/herself or by some patient's relative(s) to be shown to the doctor later. Just sayin'. 🙂

  16. Could you speak a little more clearly please..or is it just naturally your style? You are racing through the info as if your rear 
    is on fire. could have done a lot more justice to the topic

  17. Please check your subject doctor ….whole video is about bakers yeast and subject is nutritional yeast ….both are different. ..bakers yeast is live yeast and nutritional yeast or medical yeast is inactive yeast and it is extremely important for human health….I was not expecting this video from Nutrition facts.

  18. You mentioned grains near the end, but can you do more research on white grains vs brown or whole wheat grains? I heard that white is better because the hull is stripped off which is full of lectins. Or are the lectins destroyed when cooking the rice? Would like to know. Thanks
