Longevity Diet: What It Is, How It Works, and What Science Says

When people talk about the longevity diet, a science-backed eating pattern focused on extending healthy years, not just lifespan. Also known as healthy aging diet, it’s not about quick fixes or extreme restrictions—it’s about what you eat every day to keep your body working well into your 80s, 90s, and beyond. This isn’t a trend from a celebrity or a fad app. It’s based on decades of research from places like the Blue Zones—regions where people live the longest, healthiest lives on Earth.
