Quick facts
The gut microbiome is a dense community — bacteria, archaea, viruses, fungi — especially in the colon. Fibre is their main legal tender. Diversity beats any single ideal species list.
Short-chain fatty acids, colonisation resistance and immune training are the public goods. Antibiotics, travel and low-fibre patterns are the weather.
This atlas refuses a shopping list of 'good germs'. Food patterns, not miracle capsules, do most of the everyday work — and none of this is a prescription.

Microbes turning food into kimchi, doenjang, yoghurt and other living crafts — chemistry plus culture.
Familiarity 85Skin microbiome
A site-specific living film — oily, moist and dry neighbourhoods, not a sterile wrapper.
Familiarity 62Soil microbes
The hidden workforce of land — decomposers, mycorrhizae and a mostly uncultured majority.
