    My gut is filled with all that keto and low carb nonsense, sorry for that graphic description

    Thank you so much for the info. Now that explains so much. Please keep them coming.

  5. Jay Carlson Posted on November 8, 2019 at 1:19 pm

    Yeah, so just call me Prevotella!

  6. Esther Perrig Posted on November 8, 2019 at 1:21 pm

    Very interesting! Had to watch it 3 times.

  8. Esther Perrig Posted on November 8, 2019 at 1:23 pm

    Im definitely in the prevotella group. How long after eating whole food plant based can the gut bacteria shift into prevotella gut bacteria, if it was presumably in the other group?

  9. Mrs Mee Audrey Posted on November 8, 2019 at 2:04 pm

    Sooo…would chemicals in our food, water, and air aid in that growth of gut bacteria? The fact that they removed vital B17 from our diet completely might also contribute. Plus, here in the USA its not easy to find meat with the bone…which is one of the reasons Grandma's homemade chicken soup helped with what ailed you…the bone contains vital nutrients that our bodies need to help maintain that balanced gut health.

    This information is difficult to digest but it definitely worth the effort.

  11. Chris K Posted on November 8, 2019 at 2:09 pm

    Very good info. Thank you

    4.0 out of 5 starsIt's Farty Time

    Okay so this stuff really works but just make sure that you aren't within a 1/4 mile radius of anyone you want to remain friends with for the first week or so. I seriously farted every 60 seconds and pooped in between when I first started taking this stuff. I'm not kidding people. If you have to be out in public, PLAN AHEAD. Know your exits, safe haven bathrooms, potential crop dusting routes and have a prepared list of excuses as to why you keep disappearing because holding it in will likely not be a viable option.

    In my ignorance, I went grocery shopping after my first dose and consequently suffered the horror of accidentally releasing an incredibly noxious and audibly conspicuous “escapee” fart while loading a large bag of dog food. As the panic swept over me, I did the only thing I could think of and began violently fanning my nose as I directed the attention of nearby customers to an elderly man who was conveniently standing near the anti-flatulence medications. I'm not proud of it but what can I say; his shame will in all likelihood be much shorter lived than mine would've been.

    The gas does eventually subside however and is just something you have to suffer through in order to get your gut healthy I guess. Overall I feel cleaned out to put it mildly and have even lost a few pounds. Minus one star because it doesn’t dissolve all that well and can be difficult to mix. Also because I will likely lose the security deposit on my apartment now. Otherwise I am very satisfied with this product. Just be prepared people and consider yourselves warned.

    Your prebiotic powder is great; it helps my digestive system work smoothly. I had been using Dr. Gundry's prebiotic powder which costs 3 times as much as yours. Yours works even better at 3 times less the price. Thank you.

    5.0 out of 5 starsThis is the real deal!

    I just heard about Prebiotics. I have taken PRObiotics through pills and drinking Green Vibrance for years, but never PREbiotics until now. Presumably, PREbiotics make it through the digestive system better than PRObiotics and they foster the growth or activity of beneficial microorganisms to aid in digestion. I was going to buy a more expensive PREbiotic on the internet made by Dr. Gundy and decided to check Amazon to see if they were selling it cheaper than his website. It turns out that Amazon does not carry Dr. Gundy's product but that did offer Hyperbiotics' Prebiotic. It seems comparable and considerably cheaper, so I ordered a canister. It arrived in two days with Prime shipping.

    You can mix this product in anything you drink: smoothie, water, green or red drinks, whatever. I personally mix it in cold water or my daily Green Vibrance. It is pretty much flavorless. A little seems to get stuck on the bottom of my water glass each time. I drink about 2-3 scoops a day.

    Warning: you may want to start this product on the weekends. The first few days it gave me wicked gas and made me ultra-regular. I was at work and had to walk a fine line as to not draw attention to myself. There were some close calls though. This stuff really seemed to clean my system out rather quickly. After a few days, the gas issue seemed to level out and the regularity remained, but that is a good thing. Overall, I recommend this product. I plan on buying another canister soon.

    Very interesting. I know this is a relatively new area of research, but I cannot find any information about the microbiomes of individuals like myself who have no colon – I have a permanent ileostomy since 2015. I know that the vast majority of microorganisms live in the colon and there are fewer in the ileum, but does the body adapt after a total colectomy? I eat pretty much a whole-food plant based diet (with some dairy) with plenty of fibre and I also consume fermented foods (kefir, kombucha, yoghurt) all of which I make myself. I began taking these 18 months ago after surgery for the repair of a parastomal hernia, which resulted in a severe infection leaving me on antibiotics for many weeks. I was concerned about the state of my gut flora at this stage. Do you have any information about ileostomates and their gut microbiome? I am really interested to find out more. (By the way, “bacteria” is a plural word – the singular is bacterium.)

  14. Ultra4 Posted on November 8, 2019 at 2:26 pm

    can't you change the bacteria name to bac-nutella?

    Can you do a video on bananas? A lot of people talking crap about bananas. So I ask you the doctor I trust above all others. I do physical labor and I do weight training and I personally rely on bananas for energy. I eat at least 5 a day myself and bananas are a huge staple in my whole family's plant based diet.

  17. j mc Posted on November 8, 2019 at 2:56 pm

    Please do a video on the truth about ‘leaky gut’. Like ‘adrenal fatigue’ is not a clinical diagnosis and has little to no scientific basis. Both are a good way to sell supplements and ‘healing’ protocols that benefit the promoter much more then the buyer. Clicks on videos also make money and linked products.


  18. Steph Ss Posted on November 8, 2019 at 3:18 pm

    Hello commenters….there is a vast library of information if you go to nutritionfacts.org
    Go check it out.

  20. Aurora26 Posted on November 8, 2019 at 4:03 pm

    Excellent ! looking forward to the near future when more research will hopefully find out how we can treat certain bad bugs in our gut maybe with herbs etc as with food alone after such a long time of eating the wrong foods this does not always work .

  23. Ma Go Posted on November 8, 2019 at 7:29 pm

    You took the most extreme ethnic group to exaggerate your finding. AAs simply eat a lot of junk food..
    "African Americans (AAs)6 have the highest incidence and mortality rates for colon cancer among ethnic populations in the United States (3), the incidence being ;15% higher and the mortality 40% higher in AAs than in Caucasian Americans (CAs) (1)."

    Also there is an uncomfortable paragraph in the study you have not commented on:
    In a prospective study of 88,751 healthy women aged 34-59 y (the Nurses Health Study), Willett et al. (8) reported dietary questionnaire information on cancer-free subjects and the 150 incident cases of colon cancer detected within the cohort. Their analysis showed that, after adjustment for total energy intake, animal fat was positively associated with cancer risk, and those who frequently ate beef, pork, and lamb were at a 2.5 times increased risk. Furthermore, processed meats and liver were also associated with increased risk, whereas fish and skinless chicken were associated with decreased risk.

    I can remember reading a book 30-40 years ago “Taking the Rough with the Smooth “ (I think) which pointed out the difference in colon cancer rates between Native Africans and Afro-Americans which put it down to a high fibre diet in Africa and low fibre diet in America.
    Result was I’ve kept to a High Fibre Diet ever since

    Dr Gregor, is there any chance you could cover the amino acid l-glycine? It seems to have many important uses in the body, including the biosynthesis of collagen and glutathione. It’s also involved in the methionine cycle via creatine biosynthesis. It’s hard to find in plant foods. If you could also cover taurine and beta analine that’d be nice!

  42. Veganimal Posted on November 10, 2019 at 10:25 pm

    It would be more accurate to say there are two types of bacteria: the kind that like to eat plants and the kind that like to eat flesh. If you have more of the kind that like to eat plants, you have a healthy gut. If you have more of the kind that like to eat dead flesh, you have an unhealthy gut. The problem with saying there are two types of people is that people will say "I can't give up eating animals, because I'm the Bacteroides type." It takes the behavior out of the equation and makes it seem as if you have to choice.

  43. Veganimal Posted on November 10, 2019 at 10:35 pm

    Is it safe to eat ground broccoli seeds? It would be more convenient than sprouting or mature broccoli.

    Please stop conflating meat eaters with the standard American diet. In this day and age with YouTube I don't think are many people left eating purely SAD

  48. Laura Theo Posted on November 12, 2019 at 3:36 pm

    Does gut enterotype change in response to dietary change such as when somebody raised on a standard American diet switches to plant-based eating? If so, how long does it take?
