Longevity & Vitality Report

A living, evidence-linked look at what actually moves the needle on healthy longevity — food, supplements, training, sleep and disease prevention — built from real studies, not hype. We keep adding to it as new research and write-ups come in.

Diet diversity, daily fiber, and the nutrients most people quietly run low on — where each one sits on cost vs. evidence, and the detail behind each.

Diverse, plant-forward meals

Rotating 15–20+ different vegetables, legumes, nuts and herbs through the week — the "longevity salad" pattern. Mostly a shopping-list change.

Low costStrong evidence13

No single salad can be shown to “significantly increase lifespan” on its own — longevity depends on genetics, sleep, movement, smoking, alcohol, and dozens of other variables. But dietary patterns built around diverse, minimally processed plant foods, fiber, unsaturated fats and a broad range of phytochemicals are consistently linked to better cardiometabolic health and lower chronic-disease risk. The principle: make plant diversity the foundation, not one supposed superfood. 12345678910

Extra-virgin olive oil is the anchor fat — it improves satiety and helps absorb fat-soluble carotenoids. A simple base: olive oil, lemon juice or vinegar, crushed garlic, oregano, parsley, black pepper.

More is not automatically better — a huge bowl loaded with nuts, seeds and oil can get calorie-dense fast. The goal is diversity and adequate fiber/protein, not maximum volume.
