- 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.

- Level:Beginner The first microbiome: birth, breastfeeding, antibiotics and what remains In the first three years of life the gut microbiota forms, and the immune system learns from it. What birth mode, breastfeeding, antibiotics, siblings and pets have to do with it, what evens out later, and what parents can really do.

- Level:Beginner For everyone Big effect, small budget: low-cost measures for your gut What demonstrably helps the gut often costs almost nothing: slow breathing, cooled potatoes, potato starch from the supermarket, legumes, psyllium, kiwis, a stool in front of the toilet. An overview of how well each is supported, what it costs and where you can skip expensive detours.
