Fibre fermentation
Butyrate-linked guilds thrive when you feed them plants. Diversity follows the menu more than a pill.
Allies include fibre fermentation and colonisation resistance against some incoming pathogens. Risks include toxin producers when ecology collapses, and oversold tests that invent a disease from a list.
Faecal microbiota transplant is a regulated clinical procedure for specific indications in some countries. This page is not a how-to.
Body interfaces
Colonisation resistance
Occupied niches make it harder for some pathogens to bloom after a meal or a journey.
Vitamin side-jobs
Some gut bacteria make vitamin K and certain B vitamins. They do not replace a diet.
C. difficile after collapse
A famous toxin producer can bloom when diversity is flattened. Care is clinical.
Oversold stool scores
Direct-to-consumer lists rarely equal a diagnosis. Ask what decision the number changes.
Brain-gut headlines
Signals exist; causation for anxiety or autism-style claims is often oversold. Evidence first.
Eat plants, sleep, and do not treat a wellness podcast as a pharmacy.
