Probiotics labelled 'quite useless' (AMP link)

A group of scientists in Israel claim foods that are packed with good bacteria - called probiotics - are almost useless.

[...] The team at the Weizmann Institute of Science made their own probiotic cocktail using 11 common good bacteria including strains of Lactobacillus and Bifidobacteria. It was given to 25 healthy volunteers for a month. They were then sedated and samples were surgically taken from multiple places in the stomach and small and large intestines.

The researchers were looking to see where bacteria successfully colonised and whether they led to any changes in the activity of the gut. The results in the journal Cell [open, DOI: 10.1016/j.cell.2018.08.041], showed in half of cases the good bacteria went in the mouth and straight out the other end. In the rest, they lingered briefly before being crowded out by our existing microbes.

[...] The research group also looked at the impact of probiotics after a course of antibiotics, which wipe out both good and bad bacteria. Their trial on 46 people, also in the journal Cell [open, DOI: 10.1016/j.cell.2018.08.047], showed it led to delays in the normal healthy bacteria re-establishing themselves.

Dr Elinav added: "Contrary to the current dogma that probiotics are harmless and benefit everyone, these results reveal a new potential adverse side effect of probiotic use with antibiotics that might even bring long-term consequences."

    What ever would possess someone to go through with this?

        If anything, do it during colonoscopies.

        Everytime you mess around with this kind of thing, you take a huge risk that something doesn't come out right. ( pun intended )

          Food for thought:

          Colonoscopies (as practiced in the US) not only carry the risks of general anesthesia, but also the risk of bowel perforation which, once breached, has a high mortality rate.

          In the "six degrees of Kevin Bacon" sense, I am only two steps removed from someone who died from a routine colonoscopy.

            If by "general anesthesia" you mean "making unconscious", most colonoscopies don't involve that. Of the sample of 10 or so that I am aware of (me and various friends/relatives), none involved more than a sedative, leaving the patient conscious to watch the video journey. 2 didn't involve any sedation at all. Yeah, that's a bit uncomfortable, it's not something you'd do for fun, but not very high on the pain scale.

            Risk of bowel perforation is 0.05% so while it is indeed serious. it's also uncommon. The overall death rate (due to all causes, including perforation) for colonoscopies is 0.003%. (Of course, if you are in that 0.003%, it's a big deal to you.)

              0.05% = 1/2000 not a really great statistic, particularly if they're recommending it every 5 years starting at age 50, by age 75 you're at 1/400 total odds for perforation (pretty much guaranteed to be unpleasant) and 1/6667 for death. Better than working in roofing (1 death per 3333 years of labor), but not something I'd just sign off on as "routine, no worries." Note: there are methods such as DNA testing which can pre-screen for risks like bowel cancer, reducing the need for colonoscopies, if your physician is so inclined.

                Went to a presentation by a colon cancer researcher; he was working with a local family that had a 100% incidence, starting at age 20 (they were to the point of doing preemptive colonectomies at age 14) -- at this point they had four generations to work with. From the guy's data, it looked to me like the primary gene is an incomplete dominant. -- He was asked about eating fibre, and responded to the effect that "We're starting to think eating fibre may actually be part of the problem." (Well, d'oh; fibre is an irritant. Irritated tissue is more prone to tumor development.)

                As to the nominal topic, there's been a probiotic craze with pets too, and turns out it often causes intractable diarrhea.

                  The DNA test I'm referring to is used on stool samples - differentiates presence of cancerous lesions from potentially harmless observations like minor bleeding.

                  Probiotics for pets is just preying on the susceptible market. If you have a cat, let them hunt - that's the probiotics they're evolved for. Our cat has slowed down on her "gifts" she leaves by the door since she turned 12, but still seems remarkably healthy on a diet of mixed wet/dry store food plus whatever she catches for her own entertainment.

                    Yeah, most of the petfood market has become a giant scam. And the markup is insane, sometimes 5x or more by the time it hits the retail shelf.

                    My cats eat dry dog food and whatever they can catch, live to be ancient (up to 18 years) and lack major issues; also, notably, they keep all their teeth. So, yeah.

              I had a colonoscopy scheduled at 1pm. At that time, they put a breathing mask on me. Then I looked up at the clock and it was 1:30. I was pissed. Why hadn't they started yet?
              They were of course finished, after knocking my ass out in a matter of seconds.
              Everyone I know has been knocked out. At least they have some stuff you add to Gatorade now instead of drinking a gallon of that nasty chalky shit.

                I hated that "Phospho-Soda".

                The only use I could figure for Phospho-Soda is if they would control it so that its pH was held really tight, so I could use it for calibration of my soil tester. With that concentration of ionic salts, it should take quite a bit of contamination before it changes pH.. ( aka "pH Calibration Buffer Solution"). I thought it would be neat to be able to go buy something like this over the counter at any drugstore if I wanted to reassure myself my soil tester is reporting the correct pH.

                It made me seriously consider which was worse for me, the risks of drinking that much monosodium/disodium phosphate at one sitting, or the risk of an undetected intestinal problem. That stuff would sure clean someone out by causing reverse osmosis in the gut by its sheer concentration of salinity.

                    I am always looking for alternative uses for things.

                    I took that stuff as pre-colonoscopy prep. As careful as I had been trying to keep my sodium intake down, I highly questioned putting that much saline into me at one fell swoop.

                      I had seen warnings about kidney failure after taking such a heavy saline dose. I could just imagine this scenario:

                    Presenting perfectly healthy... doctor says "we need to look up your butt. Clean yourself out. Take this stuff."

                    I take it. Kidneys fail. Now doctor says "You need Dialysis to live. The costs will be $500/month. How do you intend to pay?"

                    While the healthcare company gives me copies of the forms I signed in order to authorize the colonoscopy in the first place, which holds them harmless against anything that goes wrong.

                    Knowing I signed them because I had a whole bunch of people hovering around me insisting I sign the damned thing, and I am the major traffic jam in the room for refusing to sign, not them being the major traffic jam for insisting on my signing it.

                    Then I would cuss myself out for listening to the doctor and the healthcare industry in the first place. I should have never set foot in that place unless I was already pretty damn sick!

                    While looking this stuff up, I saw it was a very concentrated ratio of monosodium and disodium phosphate, and with that many ions in play, looked to me like it would be quite stable as far as pH buffering goes.

                    Being I also have use of pH meters from time to time ( mostly having to do with soil ), I would love to be able to go easily buy a common chemical, over the counter, that also had a very stable and known pH, just as all the radio amateurs know that WWV is not just a time source, the carrier itself can be used as a frequency reference.

                    Right now, I have to go get special "pH buffer solutions" to calibrate my pH meter, or verify its working properly. If I get bad readings, I incorrectly prepare my soil, not optimal for what I am trying to grow. I really would like to have more options than checking against pHydrion paper.

                Huh. Wonder if this is a regional/national preference, or something. (I dunno where to go for stats on that.) A friend of mine who is 80 was offered anesthesia, but declined. For me, 4 buttscopes with 3 different clinics, they've never even suggested it, and I'm not aware of anybody who has had it.

                At least they have some stuff you add to Gatorade now instead of drinking a gallon of that nasty chalky shit.

                Feh. Each doctor seems to have their own favorite formula. I've had enemas and dulcolax, magnesium citrate, and gallons (plural) of polyethylene glycol (which has a wierd mouth feel, but I think is different than the chalky stuff).

        But, testing cosmetics on hairless bunnies is morally irreconcilable?

        Risk of DEATH from general anaesthesia sits around 1:100,000 - I suppose if there's nobody in the world that depends on you and the best value you have to offer is risking your life for the advancement of science, then, maybe.

        Surgeons, especially in the US, are far too quick to discount the reality of complications leading to death which are still beyond their control.

          Yes, it is. They are living, feeling beings that cannot provide informed consent. Informed consent is everything when it comes to being intentionally subjected to risk of harm from an otherwise avoidable vector.

              A human baby isn't capable of of consenting. Does that mean it's okay to burn their skin with toxic materials? Does that mean it's okay to inject them with drugs just to see what happens? Of course not. So obviously "capability of consent" is not a valid place to stand here. "Cannot" is the proper fulcrum for decision making whenever a living being with feelings is concerned.

              The fundamental issue is that such actions are amoral. You can try to rationalize your way around this. However, it is sophist nonsense no matter what you do.

              Also, informed consent isn't everything. People are forced by other people to do things against their will every single day

              At least in the USA, they are not forced to endure intentional poisoning, chemical burning and vivisection. That's the issue here. Not "you have to flip burgers in order to earn money." When the issue is one of involuntary subjection to immediate risk of harm, informed consent is everything.

              Those that cannot protect themselves are inherently in the position of ward to those who can control their circumstances. Babies, animals, the handicapped, etc. When others take advantage of that inability to protect themselves to poison, burn and dissect them, the role changes from ward to victim, and the perpetrator has established themselves as an evildoer.

            So, I have a great deal of respect for wildlife, but... on the other hand... Oscar Mayer raises pigs for slaughter, pigs that would never have been born except for the industrial farming operation, and after a short life of rapid relatively disease free growth these pigs become bacon, among other things. So, when these bacon-to-be are growing up, is it more or less valuable for a small number of them to be used for scientific / medical research, or does that become immoral because the pig can't tell us that it would rather become bacon instead of helping to develop medical knowledge?

            Nevermind the: we should all become vegans to "save the planet" for some fractional increase in human population carrying load argument - we are omnivores for a reason, and to ignore the meat eating side of our heritage is just as disrespectful to ourselves as anything we might do to our food.

              we are omnivores for a reason

              And that reason is evolution. Evolution also equips us males to take the female for sex any time we want, because we're almost always much stronger. So should we? Oh. No. We shouldn't. Because it's obviously a terrible choice, even though we're equipped for it. And why is it a terrible choice? Because we are thinking animals that have worked out principles higher than "me Ug, me take what want" based on more extended consequences than "I want sex now."

              to ignore the meat eating side of our heritage is just as disrespectful to ourselves as anything we might do to our food.

              You think so? Well, do you eat human children? They're meat, you know. How about the neighbors? Is fear of prions the only thing that has stopped you? Because if it is, fun news for you: Evolution has also provided protection for such a menu. [livescience.com] ...and with genetic engineering coming along nicely, perhaps there will be a solution to that whole prion business sooner than one might expect, now that we know what it takes.

              But... I'm going to take a wild guess and say that the reason you don't eat humans - of any age - is neither out of disrespect for your evolutionary heritage or fear of prions. It's because you know that would be an utterly amoral act. If that's the case, then you might want to re-examine why it is you think it's okay to eat other animals. Perhaps you'll find something else is going on in your decision-making process, who knows.

              These things are matters of choice. How we choose matters. Are we going to take an amoral path today, or not? This choice matters particularly to those that might end up on the lab bench or the dinner table if we choose the "me Ug" path.

              Spend a few minutes observing a cat or a dog that has a strong relationship with its owner. Does this lead you to the thought, "hey, dinner!" or... no?

              If you've made it to "dogs and cats are not food for humans", then consider: pigs (you know, bacon) are smarter than either dogs or cats. Octopi appear to be really smart, and the odds hugely favor various seagoing mammals such as whales and dolphin being smart too. Isn't that interesting? Food.... for thought. Not the dinner table. IMHO. These decisions too are based on more extended consequences than "I want food now." Thinking beings. That's us. Some of us, anyway.

                So, I totally agree: eating humans, dolphins, whales, bad.

                I've worked with piglets for medical research, you can see they're clearly smarter than cats with just a little interaction. Is eating bacon amoral? I know some people who think so, I know a whole lot more people who don't - does the democratic principle apply? If your principles put you in the "unable to enjoy bacon" minority, feel free to abstain, but until you've managed to convince a majority of the population of your position, I'd hold off on considering yourself somehow superior.

                Long before the question of consumption of domesticated animals, I want resolution on the issue of total annihilation of the wild ecosystems. Me Ug want make baby is still out of control, IMO, and until that issue gets resolved, the rest is largely academic, a matter of small margins in the bigger picture. The "thinking people" of the world have convinced themselves that the 1950+ population explosion is stopping, any day now, gonna be alright, we shall overcome, no problem mon. Call me when year-on-year human population numbers are flat. Until that happens, it doesn't matter if we eat the animals or not, we're going to drive them all extinct from habitat destruction, except for the ones we raise domestically: to eat.

                  When we're talking about the suffering of animals, and their obvious intelligence, the evidence is not only clear, it is overwhelming. Consequently, the amorality of imposing unnecessary suffering and death is profoundly evident. Denial and ignorance are the issues. These are common elements of people's thinking today, and that's why you know the latter group of people.

                  The only way I could possibly land on the "me ug" side of that one is to intentionally ignore the data. That's not something I am willing to even try to do.

                  does the democratic principle apply?

                  No. Realty is not subject to vote; democracy has no bearing on the veracity, or lack thereof, for these matters. What applies is the level of permissiveness society has for these behaviors as they relate to the facts. It is perfectly okay with the majority of our society to make animals suffer horribly, eat them, etc. There's almost always some excuse cast on the table, but none of them hold up worth a damn.

    I get the strong idea that each of us will generally initiate and maintain our intestinal flora as a matter of just living and eating. My guess the stuff we need is all around us, and we will generally call it "filth", but we need it. However, once its in, it will achieve homeostasis in a matter of a few days.

    I derive this belief from some antibiotics I took once. It was for some dental work, but it seemed to wreak major havoc in the GI tract. Nothing seemed to be working right. It seemed more like some sort of chemical processing plant all gone kaput. Things weren't coming out with the correct consistency, color, or odor. I was almost driven to the point I was going to willingly eat human dung if that's what its gonna take to reboot the system. Well, dogs do it all the time.

    About a week later, the right stuff got in, multiplied, re-established homeostasis, and all went back to normal.

    Except I now have a deep respect for all the other life I have within me, and have no intention of taking anymore of those tetracycline pills.

    If I have to have an antibiotic, I'm gonna insist on the intravenous route to try to spare the intestinal flora and fauna.

    Or, now that I know about "probiotics", I'll try that first. But it seems to be overkill if you are already at homeostasis. Just gonna waste it, as its like putting more water in a bucket that's already running over.

            Kefir is really easy to do, once you get the grains from someplace you trust. The problem is: it's continuous, you can not stop. There's a minimum size of container you'd want to use to age it in, say a quart, and there's a maximum time you want to age it, say 3 days (at most), so that's creating over 1/2 gallon of kefir per week. I mostly added strawberries or honey, blueberries were good too, and plain isn't bad, but after a few months of that much dairy product, I was done - let it go.

            Supposedly you can put the grains "on hold" and revive them later, but the quality (consistency and flavor) really improves when you establish a consistent and preferred aging cycle.

              Actually, kefir grains are some of the most resilient things -- you can even dry them or freeze them or neglect them for a long time, and they can easily be revived... as long as they were "healthy" before storage.

              I've had grains for quite a few years now. I commonly get tired of kefir for a while and let the grains sit in the fridge (in milk) for weeks or months at a time and be dormant. The longest span I think I've gone has been nine months or so -- and the grains revived completely after daily feedings for three days.

              My experience (and after reading a lot online) is that feeding daily will keep them healthiest. And as long as you're doing that, I find I can take a break for a week or two by storing them in the fridge, and they bounce right back. If I go more than two weeks or so, I generally feed them once and discard the milk after a day (whether it has clabbered or not) and usually the next feeding produces normal consistency and good quality kefir. If you go for several months without feeding, it might take a few more feedings to reestablish. But I've also seen them revive INSTANTLY after 4-5 months of dormancy in the fridge -- as in, 12 hours after taking them out, I had what looked like normal kefir... I still discarded it and did another feeding before trusting it as safe to drink, but they're hardy buggers.

              And you can certainly make smaller amounts. I don't think I've ever made more than 1-2 cups at a time on a regular basis. The key is keeping the grains small enough or few enough to make small batches. If they multiply and grow too much, you just remove some or break up a large one.

              There's a lot of lore about kefir on the internet about things you're "never" supposed to do or it will kill them -- but if you have real kefir grains, it's mostly BS. Same for sourdough bread starters -- the vast majority of info online is BS. A good quality starter is resilient and can be maintained with a lot of different feeding regimes.

              If it's easy to kill your kefir or sourdough starter or whatever SCOBY you have, it probably wasn't healthy to begin with... and frankly I'd question the quality and safety of what it was producing because healthy communities of microorganisms are necessary to keep other bad stuff from growing in them.

                I was happy with whatever it was I was making for several months... I was using quart jars about 2/3 full with whole milk, kept in an airconditioned space on a counter in our old house. My grains grew pretty large, I did split them once, but just discarded the excess (didn't have anyone interested in starting their own line). I did try slowing them down by keeping them in the refrigerator but it took a couple of batches after a "refrigerator rest" before I'd be happy with the consistency of the product again. Our current house doesn't have a good protected space like that to age the kefir in, I might make one, but that's a project onto itself and I finally just settled for store bought greek yogurt instead - I typically buy about 1/4th as much yogurt as I was making kefir, overall cost is less and flexibility is much higher.

                I think I got my grains from The Kefir Lady: https://kefirlady.com/ [kefirlady.com] it was back around 2010.

      IV antibiotics will also kill gut microbes. Believe me... My ass knows the pain of dealing with the end result of a screwed up digestive system after having IV antibiotics. While it was weeks to get significantly better, it took about 3 or 4 months to get back to normal.

      I am not a Dr... but if you think of it, IV antibiotics are placed directly into the blood stream. The blood carries nutrients and oxygen (and the IV antibiotics) throughout the entire body... including the digestive tract.

          Could well be, although thrush is usually fungal in origin (a yeast infection) while osteomyelitis is usually bacterial in origin. Though the heavy antibacterials could alter your oral environment enough to let the fungus play ball. You may simply have not been exposed to C. Albicans in the period you were on treatment, or the antibi's may not have killed off enough mouth bacteria to make that happen. Or you might be really good about your oral care and/or other hygiene, as good brushing habits (including tongue stimulation) are supposed to also defend against it. Or it might have been the kefir. Hope to try it someday. ;)

      I can guess why this happens, though: Google probably adjusted its algorithm to take into account "bounce rate", that is to say people who leave the site after a very short period of time because it wasn't what they were looking for. Some SEO specialists figured this out, determines that 8 seconds is long enough to ensure that Google will think the user didn't bounce, and delays showing the article for that amount of time to reduce the bounce rate. Google, in turn, to counteract this, will try to set this up so that your browser begins processing the JS on the page before actually showing you the page. Meanwhile, of course, you're sitting there thinking "Give me the f***ing article!" But that's irrelevant in the ongoing wars between Google and SEO folks.

      What I hope this research does not do is start to derail the treatment of colitis and similar conditions with gut flora diagnosis and adjustment. 20 years ago the only answer even considered by many "respected" physicians was removal of the affected gut, often resulting in a colostomy bag, even in young patients. To go that route without even making a solid effort at gut flora restoration, by whatever methods, is a major pinnacle of Hippocratic violation, IMO.

        Not only is it a tiny sample size, it's completely unconfirmed. Until it has been reproduced with much larger sample sizes it can be safely filed into the bullshit bin.

      Following a few days of antibiotics or some consecutive, heavy drinking you won't have healthy gut flora.

      Also, those probiotics keep the plain yogurt prices down: If you pick up any non-UHT pasteurized milk off the shelf, bring it to 50c, mix it with 100mm of a probiotic and cover it for 8-12hr in California summer shade/night (25-28c?), you'd get pretty good yogurt. So prices has to be kept low enough to make this too much of a bother.

      Agreed. The doctor in charge of the study doesn't seem to be against probiotics, but more saying that they will need to be personalised rather than off-the-shelf.

      Dr Eran Elinav said it was wrong to expect an off-the-shelf probiotic to work for everyone.

      He says that in the future probiotics will need to be tailored to the needs of individual patients.

    Certainly an indicator of something worthy of continued study. Not a conclusion, though, instead two separate studies revealing different things. Therefore confirmation would be in order to overturn them. (And coming from the same organization labeling it "studies" makes it read like settled science which AFAICT this ain't).

    And the lead scientist's comment in TFA, "Dr Eran Elinav said it was wrong to expect an off-the-shelf probiotic to work for everyone." I can fully agree with that statement, but there is a long stretch between saying it's not effective for everybody and is completely ineffective for anyone.

    The one article says that probiotics don't colonize or last in the system, which appears to ignore that maybe they don't have to colonize to do a job as they pass through akin to some medications which are rapidly excreted. Then there is a suggestion that they can do "long-term consequences"? So which is it? They're useless or they're damaging?

    Interesting results and possibly true. But, as usual, initial results not worth the 15 minutes of hype the media mill gives it.

    ${X} is mostly useless and can actually hurt you.

    Probiotics
    Homeopathic 'medicine'
    Pet rocks
    Facebook
    Windows

      At first I was going to mod that funny. Then I thought about Touche. Then I realized it was pretty insightful.

      So since I'm so undecided.... I figured whatever it was it was Interesting. ;)

      And you've inspired me to go get a couple googly eyes and a rock so I can have a Pet Rock on my desk. I think I'll name it Kid. Maybe I'll do a long term study of which does more damage to me, the Pet Rock or Windows.

    sheesh, people now-a-days; it's all "me! me! me!".
    ever consider what happens after you happily made that thing the brown-ice-cream emoji is based on?

    what would totally interest me is how the "septic tank" or "waste water treatment plant" handles the patients in the study.

    they should have let them poop into 20 different septic tanks and see how it develops.
    how much does it smell? does the volume only increase or does it continuously collapse? how "clean" is the runoff-water of the septic tank etc. etc.

    i guess some people don't CARE where their waste goes and what happens to it ...

    on a side note: NATTO makes for really solid poop :] and kimchi (sauerkraut with chilli powder) supposedly has more vitamin C AFTER fermentation then before? where did it come from? also, bread is made with yeast. they probably DIE in the baking process and are DIGESTED and RESORBED when eating bread, non?

    This shows at best that probiotics don't colonize the gut. That doesn't mean that probiotics aren't good for you, just that the commonly assumed mechanism is wrong.
