If you want to live longer, don’t simply eat your fruits and vegetables. Make sure you eat the right kinds. In a study published in the journal Circulation, Harvard researchers analyzed 30 years’ worth of nutrition data from more than 100,000 men and women. They found that eating two servings of fruit and three servings of vegetables every day is best for longevity. But certain fruits and vegetables provided the biggest benefits, especially green leafy vegetables such as spinach and kale, cruciferous vegetables such as broccoli and brussels sprouts, and citrus fruits and berries. Unfortunately, eating more than five servings of fruits and vegetables a day does not provide additional health benefits.
