What is a healthy microbiome?
No single species list fits every diet, age and latitude. Diversity and fibre-fed functions are the safer frame.
Researchers still argue how to define a healthy microbiome without freezing one nation's diet as destiny.
Live biotherapeutics sit in trials. Public pages stay at the concept level.
Open questions
Can stool tests diagnose ordinary life?
Some clinical uses exist. Wellness rankings often outrun evidence.
How personalised can diet get?
Glucose responses vary. Long-term outcome data still lag the apps.
Which live therapeutics will last?
Defined consortia are being tested. Manufacturing and regulation are the bottlenecks.
How do we talk about causation?
Transplants in animals are not human destiny. Ask for trials, not testimonials.
The frontier is functions and fibre more than inventing a more famous strain.
