Myth
There is one ideal species list.
Reality
Healthy communities differ. Fibre-fed diversity is a better target than a celebrity strain.
Darker cells mean a higher score for this topic on that metric.

Quick answers
Where should I start with Gut microbiome?
Read Identity → How they live → Body & health, then use compare rails.
Is this page advice for Gut microbiome?
Public-health education — not a care plan, prescription, or outbreak briefing.
What does the local lens add?
It names everyday desks for Beneficial allies before English norms look universal.
Are the scores a ranking of Gut microbiome?
No — editorial 0–100 browsing aids inside this atlas only.
How do I compare Gut microbiome to neighbours?
Use related cards and best-of / quiz rails after the first three chapters.
Which chapter is densest?
How they live and Body & health carry mechanisms; skim Identity first.
Marketing taught a decade that you are missing one magic bacterium. Ecology taught that functions and diversity do the work.
Myths below are common queries. They are not medical advice.
Myths vs evidence
Myth
Sterile guts are cleaner and better.
Reality
Germ-free animals develop abnormally. Occupied niches are often protective.
Myth
A probiotic cancels any junk diet.
Reality
No capsule outruns fibre, sleep and not drowning allies in unnecessary drugs.
Myth
You must buy a monthly stool score.
Reality
Most people need food patterns more than a subscription graph.
Myth
All gut bacteria are the same as pathogens.
Reality
Pathogens are a minority. The community is mostly metabolic machinery.
Myth
Autism or mood is just a missing microbe.
Reality
Associations are researched; simple replacement stories are not established care.
If a claim sells the one true microbiome, ask whose diet it froze.

Live microbes in food or capsules — strain-specific guests, not a whole microbiome and not medical advice.
Familiarity 90Fermentation
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.
Familiarity 48Nitrogen cycle
How microbes move nitrogen between air, soil, water and food — plus the industrial shortcut that feeds billions.
