How to Develop a Healthy Gut Ecosystem

  • This is good news for people who may like steak very rare-ly (a pun on rare ). If this destructive bacteria that produces TMO's decreases because of the rarity of having our rare steaks, how does the meat get digested if there is less of the correct bacteria to help digest it ?
    Also it sounds to me like this bacteria that produces TMO is better for the help of decomposition of animal flesh then to help our bodies function best.

  • Probiotics are available everywhere, there should be probiotics for Vegans, and those designed for Meateaters. I want only the healthy probiotics, not the common ones for the average SAD eater….

  • Most of the stuff about gut bacteria will be exposed as pseudoscience which vegans used as rationalizations for their insane lifestyle. Do you idiots seriously believe that some broccoli on your table will protect you from cancer?

  • mostly when i look into these research its very flat out, i mean they don't make a distinguish between organic (bio-dynamic) (grass-fed) and regular products there seems like a difference because of what animals eat, antibiotics and what we as humans assimilate from what is in these products right ?
    so i would argue that you have meat and you have meat, like any other product there are big differences between these qualities of products.

  • They use FMT to treat the spectrum of autoimmune disorders. I have been low fat, unprocessed, sugar free vegan for 2 yrs and I still have MS. I've definitely seen huge improvements and I know they will keep coming but I wonder if FMT might still help me.

  • I wonder if high consumption of meat & highly processed food leads to the TMAU disease (which is when the body can no longer break down TMA at all) which leads to bad body odor when consuming high choline foods.

  • I went Vegan for 1.5 years. Never felt worse in my life. Constant head aches and low energy. I made sure to eat tons of fruits, veggies, nuts, seeds, healthy wheat breads, ect. Everything organic and whole. Recently, I started eating meat again. Feel SO MUCH BETTER. Still, I eat TONS of fruits and veggies daily, but now also eat good, high quality, organic meats, and I feel really good. Not too sure if there was something I was missing, or all bodies are different and some do better with meat and some do better without.

  • Thank you so much, Dr. Greger. Your voice is one of the most consistently unbiased and science-driven ones out there. My father has stage IV lung cancer. I convinced both my mom and dad to ditch the animal products in their home and try the Gerson Therapy. His first lab results following the diet switch shocked the technician and he has since cancelled the second round of chemo (which even his doctor said "will not cure the cancer"). He also no longer needs his blood pressure medication. I've sent them and several friends and coworkers links to your podcast. I'll be picking up a copy of How Not to Die soon! I'm so grateful people like you exist!

  • There are companies emerging now that claim to test our microbiome and make specific dietary and supplemental recommendations based on these findings (e.g., Viome, ThryveInside). Not pressuring you to endorse anyone, but I'm just wondering whether you think there's any merit to these tests? I have IBS, lymphocytic colitis and a hiatal hernia/GERD. I went vegan approx 8 months ago but still struggle with episodes of GI problems. Wondering if a test like this would help me figure out what, within a plant-based diet, will help me stay on track.

  • Some plants also have choline, but there is something to them that inhibits the conversion of TMA into TMAO. Conclusion? If you eat eggs, have them with a bunch of broccoli.

  • I am a fan of yours Dr Greger but it does seem like there bias. You clearly don't approve of any supplements other than vit D and B12. And granted there are many awful supplements… but I believe in educating people on what vitamers and chelated minerals are the good guys because it could be the difference between them needing pharmaceuticals or avoiding them. I think the last bit about L-carnitine, they were trying to say that there beneficial functions of this amino acid (building block of protein) like the transportation of fat into mitochondria to boost energy production and reduce fat mass. And instead of highlighting it's benefit and use you labelled it purely as a health risk. I'm a little disappointed in this. Also the video is not about the title "how to develop a healthy gut". Dr Greger I love you but please educate, don't just give one side of the story. Much love. From, a fellow nutritionist who you have inspired at times 💙🌱

  • I know pharmaceutical antibiotics harm our microbiome. Would something like fire cider, which incorporates foods with antibiotic properties such as garlic, honey, and ACV also damage our microbiome?

  • Some people advocate the use of HCL and digestive enzymes in older folks and claim that as you age, your body produces less and less stomach acid and enzymes and therefore supplementation is necessary…do you agree?

  • If strictly plant based diets are best for optimal health, why aren’t there any traditional cultures that survive on vegetarian diets that have high life expectancy and numbers of centennials?

  • PLANT POWAH all the way! =P

    Whole food vegan diet is the best. There should be so many more doctors like Dr Greger promoting plant based nutrition. Makes you wonder doesn't it, what the hell is the point of that hippocratic oath when most doctors promote harm.

  • The authors wisely caution against extrapolation of their findings with egg ingestion and TMAO production to changes in policy for the minimum choline intake recommendations for individuals. Neither the present studies nor the recent prior investigations into the TMAO meta-organismal pathway examined the issue of minimum daily choline requirements.

  • Eggs seems to be 100% fine – further study and results.

    "A study in 2016 in the American Journal of Clinical Nutrition looked at more than 1,000 middle-aged Finnish men and found that neither eggintake (one a day, on average) nor cholesterol intake was associated with an increased risk of coronary heart disease. This was true even among those who had a particular genetic factor that affects cholesterol metabolism and therefore put them at higher risk. There was also no significant impact on the thickening of the carotid artery (the main artery going to the brain), which is an indicator of hardening of the arteries (atherosclerosis).

    Similarly, an analysis of eight observational studies, published in 2013 in BMJ, found no relationship between eggs (up to one a day, on average) and heart disease or stroke in half a million people who were followed for 8 to 22 years.

    More recently, an analysis of seven studies, published in the Journal of the American College of Nutrition in 2016, found that people who had a high egg intake (generally considered seven a week) had a 12 percent reduced risk of stroke compared with those who had a low egg intake (less than two eggs a week), after the researchers accounted for such variables as smoking, age, sex, and exercise in most of the studies"

  • Its OK to eat eggs again – no association with CV events.
    In conclusion, in the present study we examined the association between egg and cholesterol intakes and the risk of CAD and carotid IMT in a population with an exceptionally high prevalence of the ApoE ɛ4 allele. We did not find any indications of the relation of moderate egg consumption (up to 1 egg/d) or moderate-to-high dietary cholesterol intake with increased CVD risk, even in these highly susceptible individuals. Hence, although our results are based on a rather small population, the findings suggest that removal of the recommendation to limit dietary cholesterol intake (including egg consumption) does not involve a marked risk for population health.
