What you eat is one of the most powerful levers you have for healthy aging. Decades of research — from Blue Zones to randomized trials — point to a few consistent patterns: eat mostly plants, prioritize whole foods, and don't stress about perfection.
Key Insights
The Mediterranean Diet
strong evidenceConsistently ranked the top dietary pattern for longevity. Rich in olive oil, vegetables, legumes, fish, and whole grains, it's associated with up to 25% reduced cardiovascular risk and lower rates of cognitive decline.
30 Plants Per Week
strong evidenceResearch from the American Gut Project shows that eating 30+ different plant species per week leads to a significantly more diverse gut microbiome — a key marker of metabolic and immune health.
Time-Restricted Eating
moderate evidenceEating within a consistent 8–12 hour window may improve metabolic markers, reduce inflammation, and support cellular repair through autophagy. Research is promising but still evolving.
Ultra-Processed Foods
strong evidenceHigh consumption of ultra-processed foods is linked to increased all-cause mortality, obesity, and chronic disease. Reducing them is one of the simplest dietary upgrades you can make.
