  5. When conducting science, a hypothesis often precedes an experiment—perfectly normal.  Even if the hypothesis isn't confirmed, something has been learned—good science.  An agenda, on the other hand, is a lousy thing to precede an experiment with.

  7. I've always wondered about that. I mean, I throw in million of bacteria and I don't know if it's the right kind for the food I eat. I always thought the right bacteria will be there according to what I eat.

  10. Wouldn't be surprised if these naturally present bacteria on foods are the right type for the type of diet people consume and adding extra random colonies just results in more indigestion… Yet funny how rats do fine, whereas humans die like flies from the same intervention, so much for the usefulness of animal experiments. Also, suppose these people suffering from pancreatitis also had a leaky gut or even due to a leaky gut, feeding them any food might be bad for them. I think this type of disease might be one that's reversible with fasting. Too bad the only clinical data that might occur on this topic will likely come from fasting centres and is thus likely to be biased…

  11. I have always had great results from probiotics even since the 90s. I remember many a time when the probiotics really helped me out. I was eating out a lot.

    Everything worked even as it was supposed to. Older probiotics did not work as well, and I figured out later it's because they were not as strong as they were when I first bought them.

    I was using simply acidophilus bifidus. I wasn't even using the fancier probiotics.

  16. MORE stuff on probiotics!!! Local holistic doctor is diagnosing majority of patients with leaky gut and is prescribing probiotics. Your messages are the basis of life -THANK YOU.

  17. There is no one "magic bullet" that will fix human issues! It takes time for the body to heal, it takes time for recovery. Allow yourself time to improve.

  20. Ok, if you have pancreatitis. don't take a probiotic, at least not the one in the experiment referenced. Beyond that, there are no obvious conclusions. My observations are that most probiotics are useless because they don't survive the stomach, at least the stomach of a healthy individual. And probiotics are not useful if you are not going to feed yourself a mostly vegetarian / vegan diet. After all, most people take probiotics because they are not pooping properly. I take a probiotic, one designed to survive past the stomach, but only once a week. Same with vitamin D3, I take it only once a week, and not on the same day as the probiotic. Taking the same crap everyday is probably not a good thing, because there is a likelyhood that they will interfere with each other.

  22. Consumer Labs looked at probiotics, mainly from the standpoint of whether they delivered the type and number of organisms they claimed. They also looked at several brands of kefir, the fermented milk beverage, somewhat similar to yogurt. They found that the kefir contained orders of magnitude more organisms than the supplements, in the trillions per serving. There are hundreds of studies in Pub Med on the benefits of kefir, including that made with soy milk. In one study the number of isoflavones doubled and total phenolic content increased 9-fold. I make my own following an extremely simple process I found on Youtube. I buy Trader Joe's organic soymilk in the sealed cartons. I pour out about three ounces into another container and replace it with three ounces of Trader Joe's plain milk kefir. I then replace the lid loosely and let it stand at room temperature for 3-4 days, shaking it periodically. The result is a creamy, tangy delicious drink that I either drink straight or pour over berries.

  23. I've been taking probiotics for nearly 20 years and this is the first I've heard of any possible risks. Since it's a popular supplement, this video deserves a follow up.

  24. No pills or supplements, just eat a whole foods plant based diet… Well make it 95% whoole foods, 5% junk food for those cravings lol.

  26. A few years ago I had a bout of what I thought was the beginnings of irritable bowel syndrome or something similar; the symptoms quickly changed and became a really bad case of GERD (Gastroesophageal Reflux Disease). The proton pump inhibitors the doctor prescribed only gave very temporary relief (an hour or so) and seemed to make things worse over time. I tried some different brands of probiotics and one seemed to help (none made it worse), but I did not want to keep taking it forever. To that point I had avoided eating raw produce since I was worried about foodborne illnesses – I had always lightly steamed my veggies. Then I read of the hygiene hypothesis and decided I didn't have anything to lose – my gut was messed up – so I started eating raw foods daily – mostly fresh leafy greens (lots of surface area for microbes to cling to) and frozen berries. I also increased my consumption of resistant starches (I try for a variety). I got better.

    It is interesting to note that proton pump inhibitors have anti-bacterial activity – they interfere with the formation of biofilms.

  29. There's a lot of hype about 'vertical farming' – referring to indoor growing typically using hydroponics and artificial lighting – being the way to feed people in the future. I have a lot of questions, e.g., will they really be able to produce more calories than regular agriculture given the same level of inputs? What about phytonutrients, many of which are produced in response to stressors such as UV light and insect predation? Now I'm left wondering about microbes/the microbiome. Do some of these probiotic microbes have life cycles that include being in the soil or in the guts of other animals (insects, etc.)?

    We are so accustomed to thinking of microbes as pathogens, but most are not. Many plant viruses, for example, provide benefit to their host plants. Here's a really great video on plant viruses and their implications for agriculture:

  31. Our yard is full of various cabbages that are harvested in the late fall…someone recently said "there's enough here to make a crock of kraut" …that's EXACTLY why it's grown…

  40. I've always wondered why one needs to take probiotics so long? Why is it you are not introducing bacteria to your gut via pill and this new type of bacteria stays there? If it were the case, then 1-2 months, 1-2 bottles should do the trick?

  42. My question is do current farming practices have an effect on amount/type of probiotic strains, and does washing them any certain ways reduce efficacy?

  46. This video left me with unanswered questions? Are probiotics supplements good? Or are we better of to eat fermented foods and drink Kombucha?

  50. One of the problems I see here, is the term "pro-biotic" as if it is just one single organism, there are hundreds of different pro-biotic bacteria, that react with our bodies in different ways. and, we also must take each individuals own genetics and diet into account.

    Imagine if we used the word, "food" the same way we generalize "pro-biotic" I could say food can kill you and is dangerous, and technically I would be correct. so would you agree that what specific foods and quantities is consumed is important?

    L. acidophilus will affect someone different than say B. longum , and as many others have stated in the comments section, what a person likes to eat will have effect on what populations of pro-bacteria will flourish in our bodies.

    As for the pro-biotics in food, I would think that most processed food is sterile, with the intention of the manufactures wish of increasing shelf life. nuked, heated, treated, anything to make that product not rot on the shelf.

    I would go as far as to say that any bacteria on fresh produce, will not only vary by how its grown, ( Organic vs Non Organic ) but also in the location, and even the variety / cultivar of the veggie or fruit.

  54. Puradyme for quality probiotics and enzymes in the world. Look up Lou Corona and Liferegenerator on YouTube. Many accounts of people improving autism, tumors, etc…

  55. when I take 100 billion probiotic it always gets rid of my bloating and honestly helps. perhaps it is bad for some but I can noticeably tell an improvement 😀

  57. Oh my goodness! I'm glad I stopped taking them. Switching my diet make the trick and I didn't need them anymore, thanks to you Doc!

  58. I'd be interested to see results for fecal transplants. Even fecal transplants after probiotics. Given that most of the immune system if focused on the gut, one would expect to see a healthy patient eliminate harmful bacteria and provide material for an effective transplant. Additionally, the remaining bacteria would be less prone to immune attacks, which seems to me the most likely culprit for probiotics in pancreatitis.

  62. I think if you are transitioning from the SAD into a plant-based diet, probiotics are a good "quick fix" to repair gut flora. After the transition, you need not take anymore.

  63. Most probiotics sold are dairy based. MEH.

    Water Kefir, good ol sauerkraut and Apple cider vinegar or Kombucha are vegan af and inexpensive.

    Also FOS made with polyfructose are toxic af. Beware

  65. Aren't people recovering surgery likely to be on antibiotics? Then giving probiotics would be, well, silly. And if you have a properly functioning stomach, the typical probiotic pill is not likely to survive transporting live bacteria to your lower GI anyway. But from my perspective, a lot of people do not have totally functional stomachs, so….. Many questions here.

  66. Yeo Valley Organic Live Yogurt? It contains specific bacterial live culture such as Lactobacillus Acidophilus, Bifidobacterium and also Streptococcus Thermophilus.
    Is it healthy? Or should it be considered unhealthy as per dairy products!

  67. Many thaanks Dr. Greger 🙂 But please a little bit slowlier spoken. For non-experts its difficult to understand and remind. Always stopping and going back is also not so good.

  69. after watching this channel for months then i started to question the videos. cherry picking data so u won't eat animals products.
    Even when they seem legit they are not:/ why cant vegans stick to the truth :/

  71. Good to know this. Thanks. I have a request: could you answer these queries? 1. If produce contains beneficial bacteria, I suppose those would be destroyed on cooking? So cooked vegetables are not a good source? 2. Washing by rubbing with fingers under a running tap then rinsing does, I have read, remove 50% of chemical residues. I suppose washing also removes the bacteria? 3. Washed and peeled fruit though eaten uncooked too would be a poor source of the bacteria? 4. May I assume that having plenty of a variety of fibrous prebiotic foods i could hope for the best, that the tiny amounts of bacteria still left in the washed fruit and cooked vegetables would multiply and flourish in my body and keep me healthy?

  80. Together with the recent research by Justin Sonnenburg et al in the famous FeFiFo study, this suggests that the benefits of pro-biotic foods is due to the post-biotics chiefly lactic acid. Diverse foods per se were not reliably beneficial, unlike in rat studies, while fermented foods were uniformly a benefit so it's either the bacteria or their byproducts that improve everyone studied and since a variety of fiber implies a variety of pro-biotic bacteria it must be the post-biotics.
