Apples
One of the healthiest fruits you should be eating is one you probably already are: the apple. The Iowa Women’s Health Study, which has been investigating the health habits of 34,000 women for nearly 20 years, named apples as one of only three foods (along with pears and red wine) that are most effective at reducing the risk of death from heart disease among postmenopausal women. Other massive studies have found the fruit to lower risk of lung cancer and type 2 diabetes—and even help women lose weight. In fact, one of the only things that could make an apple unhealthy is mixing it with sugar, flour, and butter and stuffing it into a mile-high pie. Instead, have one as an afternoon snack with a tablespoon of peanut butter, or add slices to sandwiches or salads.
