Description

Ro Osawa and four co-authors test a personal fiber picker: a lab screen that ferments a person's gut microbes against many fibers and names the best match. Their 2026 trial starts from a known puzzle, that fiber supplements help some people and not others. No proven way existed to choose a fiber ahead of time.

Eight healthy adults took both their best-match and worst-match fibers in turn. The matched fiber raised helpful gut acids over baseline at group level, while the unmatched one did not. Seven of eight people did better on their match. Yet the screen's score gap did not predict how big each person's gain would be. The authors call the results a proof of concept that needs larger trials.
