Drudge Retort: The Other Side of the News

Probiotics are living micro-organisms that are taken by millions of people to boost their microbiome or to restore their gut ecosystem after a dose of antibiotics. Yet questions remain about whether they actually work. To find out what really goes on in the gut when people ingest probiotics, immunologist Eran Elinav of the Weizmann Institute of Science in Israel, and colleagues, sampled the microbiome of healthy volunteers directly using endoscopies and colonoscopies. Most other microbiome research relies on faecal samples as a proxy for gut microbes. Next the researchers measured what happens to the microbiome of people who take probiotics in the hope of restoring their microbiome after antibiotics. Twenty-one volunteers took an identical course of antibiotics and were then assigned to one of three groups.

Ouch. Don't mess with gut bacteria

I wonder how yogurt affects gut bacteria? It's not as loaded as a probiotic but still poseses many of the same bacteria.

Lots, or even most, of the fad diet suggestions are not really good for you, and even can be quite detrimental.

This isn't surprising to me at all.

Probiotics weren't well supported to begin with and there's a lot of information coming out pointing to antibiotics and microbiome changes being significant for long term health.

In fact, it's a common method in microbiome research to clear out an animal's (usually a mouse) microbiome then replace it by feeding filtered poop from other mice.

The research also showed that while probiotics colonised the gastrointestinal tract of some people, the gut microbiome of others just expelled them. There was no way of telling from their stool sample which category people fell into. "Some people accept probiotics in their gut, while others just pass them from one end to the other," says Elinav. They found that the probiotic colonisation patterns were highly dependent on the individual. That tells us that the concept that everyone can benefit from a universal probiotic bought from the supermarket is empirically wrong, he says.

Ethnicity must play a significant role in genetic dietary considerations. I can eat dairy - require some dairy. My ancestors did so as well, apparently surviving fairly long dark winter weather with goats kept inside the house. My Korean friend cannot eat any dairy products. Interestingly, we both have traditions of pickling foods - which I never gained an appreciation for including in meals. Only this last year I'm beginning to ferment foods, thanks to YouTube foodies.

So we should never take antibiotics?

But we need probiotics to balance the use of antibiotics. When my rheumatologist in the 1990s gave me multiple courses of antibiotics to try to "kill" items in my blood, I developed c. Diff colitis and almost died b/c my gut flora got so out of balance without probiotics.
