Microbial diversity
Why many different species keep the gut stable. 1 chapter – expand
- Level:Beginner For everyone Your gut in ten minutes Who lives there, what do they do, and why is balance more important than individual germs? FibrePlant diversityFermented foodsAntibioticsExerciseTests and diagnostics Well supported How we rate the evidence Established Recommended in medical guidelines or supported by several consistent meta-analyses of randomised human studies. Well supported Several randomised studies in humans with largely consistent results. Promising Single randomised or controlled studies in humans, not yet independently confirmed — or many consistent observational studies. Plausible Two cases: first observational or pilot studies with small samples — or a settled basis that is not in dispute, such as movement, sleep or meal pauses. But not tested in humans for symptoms. Experimental Barely studied in humans. Mainly lab and animal studies or theoretical reasoning; whether it helps is open.
