Chapters
Take the gut check and we will sort the chapters by relevance for you.
Microbial diversity
Why many different species keep the gut stable. 1 chapter – expand
- Level:Intermediate What a household shares: microbes between people, dogs and cats People who live together swap bacteria constantly: through hands, kitchen, bathroom, kisses and the animal on the sofa. What studies on shared bacterial strains show, what is useful about it, which pathogens and resistant bacteria really do get passed on, and why shared bacteria are not proof of transmission. Gut infectionsAntibiotic resistanceMouth and teethAllergiesAntibioticsBody weight 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.
Digestive function
Stomach acid, bile and enzymes as groundwork for the gut. 1 chapter – expand
- Level:Intermediate Acid blockers (PPIs): what they change in the gut and how to stop them properly Proton pump inhibitors are among the most widely used medicines in the world. They are very effective for reflux and ulcers, but change the gut flora and nutrient absorption. What is established, what is not, and how to stop them.

Immune system and inflammation
The gut as the body's largest immune organ. 2 chapters – expand
- Level:Intermediate Allergies and intolerances: how the gut learns to tolerate food Every day the gut has to tolerate foreign protein. How this tolerance develops, what role bacteria, stomach acid and skin play, and why many people feel allergic without being so.

- Level:Intermediate Skin and gut: what there is to the gut-skin axis Acne, rosacea, eczema, psoriasis: which links to the gut are proven, where a real disease is behind it, and where the hype begins.
