People that struggle to eat the often-recommended nine servings of fruit and vegetables each day can relax: The latest research from Harvard, based on 26 studies of 2 million people from 29 countries, found that two and three daily servings of fruit and vegetables, respectively, were linked to the most longevity. Compared to only two servings of produce per day, five servings lowered the risk of death overall by 13 percent, cardiovascular disease by 12 percent, cancer by 10 percent and respiratory disease by 35 percent. Green, leafy vegetables, including spinach, lettuce and kale, and fruit and vegetables rich in beta carotene and vitamin C, such as citrus fruits, berries and carrots, showed benefits. Starchy vegetables, like peas and corn, fruit juices and potatoes, did not appear to reduce the risk of death.
