- 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. FibreExerciseStressPrebioticsFermented foodsConstipationBloatingShort-chain fatty acids Promising 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 Diverticula, haemorrhoids and fissures: what can go wrong at the end of the gut Three common problems in the lower gut that people rarely talk about. Why nuts and seeds are fine with diverticula, why mild diverticulitis often heals without antibiotics, and what your phone on the toilet has to do with haemorrhoids.

- Level:Beginner When the supplement itself is the problem: iron, magnesium, excipients and more People struggling with their gut often take several supplements at once. Some of them trigger exactly the symptoms they are meant to relieve. Which products typically cause diarrhoea, constipation or bloating, what tablets contain besides the active ingredient, and how to find the culprit.
