Want to live to be 100? It's tempting to think that with enough omega-3s, kale and blueberries, you could eat your way there.
But one of the key takeaways from a new book on how to eat and live like "the world's healthiest people" is that longevity is not just about food.
The people who live in the Blue Zones — five regions in Europe, Latin America, Asia and the U.S. researchers have identified as having the highest concentrations of centenarians in the world — move their bodies a lot. They have social circles that reinforce healthy behaviors. They take time to de-stress. They're part of communities, often religious ones. And they're committed to their families.
