Slash your sugar consumption
Blue Zones dwellers consume about a fifth as much added sugar as we do. Centenarians typically put honey in their tea and enjoy dessert only at celebrations. The lesson to us: Try not to add more than 4 teaspoons of sugar a day to your drinks and foods. Have cookies, candy and bakery items only a few times a week. And avoid processed foods with sweeteners—especially when sugar is listed among the first five ingredients.
