Story summary

A study by Italy's National Research Council identifies 91 causal links between gut microbiome features and age-related traits, highlighting gut bacteria's role in aging.
Researchers employed Mendelian Randomization to confirm these connections while reducing confounding factors.
A key finding connects the microbial pathway "purine nucleotides degradation II" to lower levels of apolipoprotein M (ApoM), linked to cardiovascular health.
Reduced ApoM levels increase cardiovascular risk, especially in older adults.
The study suggests personalized microbiome-targeted interventions could help address age-related diseases.
