Eat your yellows, oranges and reds

According to the results of a long-term study of 15,318 participants (published in the Archives of Internal Medicine), eating fruits and vegetables high in the powerful antioxidant alpha-carotene can lower your risk of death from any cause, including heart disease and cancer, by up to 39 per cent. Vegetables rich in alpha-carotene include yellow or orange fruit and vegetables, such as carrots, sweet potatoes, pumpkin, squash, peppers, cantaloupe melon, apples, and dark green vegetables, such as broccoli, green beans, kale, spinach, turnip greens, collards, and lettuce.
