Feb 13, 2026The Microbiome-Longevity Connection: Centenarian Studies, Gut Diversity, and Prebiotic StrategyCentenarian microbiome studies consistently show higher diversity, more short-chain fatty acid producers, and distinct bacterial profiles compared to age-matched controls. Dietary fiber remains the strongest intervention for diversity. This article maps what the longevity-microbiome evidence shows and what remains speculative.
Jan 31, 2026Gut Health and Microbiome Optimization: Fiber, Prebiotics, Probiotics, and Testing OptionsThe gut microbiome influences metabolic health, immune function, and even cognitive and mental health. Evidence supports dietary fiber as the primary driver of microbiome diversity. Targeted probiotics have strain-specific evidence for IBS, antibiotic recovery, and immune support.
