"In a clinical trial of 19 healthy men, researchers found that a daily bottle of beer — alcoholic or non-alcoholic — changed the composition of the men's gut bacteria over four weeks. Specifically, either type of beer boosted the diversity in their gut microbes."
Caveat:
"In general, greater diversity in gut bacteria is considered better than less diversity. Experts cautioned, however, that it's unclear whether people would gain any health benefits from the gut changes seen in this short-term trial."
And this answering my #1 question: whether the effect could be achieved without alcohol. A secondary question: is there a ketogenic way of getting this effect? Beer tends to be high in carbs...
