Gut microbiome may reveal inflammation and future disease risk better than age

What the research found
Study (observational). Eriksen, Brix and colleagues report in Nature Communications on paired stool and blood from 1,199 adults in a Danish cohort. Gut microbiota composition explained more variance than chronological age for 97% of 30 plasma cytokines and 84% of 19 physiological measures. People with a Bacteroides 2 enterotype showed an inflammaging-like profile modeled up to 37 years earlier than other enterotypes and higher later hospital diagnoses over about eight years of follow-up. A high-diversity richness enterotype tracked with lower inflammation. Association is not causation. A commercial probiotic for this claim is weakly evidenced. Food-first fiber is educational, not a treatment.
Evidence level: Human study. A study in people, but an association isn't proof of cause.
