People of the Blue Zones® hold the secret to a longevity diet. People in these areas have a diet that consists primarily of seasonal fruits and vegetables, whole grains and beans all year long. Leafy greens are key, particularly spinach, kale, collards and chard. Whole grains have high levels of fiber and offer a wide spectrum of nutrients. Beans are a great superfood and the cornerstone of most centenarian diets, including fava, black, soy and lentils. Meat, fish, dairy, eggs and sugar are consumed very sparingly.
