Apples, celery, peppers and cucumbers —turns out, some of our favorite, go-to healthy snack options are also some of the wettest. And the wetter, the better according to the experts at Fit Sugar. "Foods rich in water tend to pack fewer calories into bigger servings and come with added fiber." Broth based soups count, too! "These are known as nutrient dense because the ratio of nutrients to calories is high." Just remember, a good snack is a balanced snack. Try pairing "wet" snacks with protein packed nuts or nut butter for a hunger-killing afternoon pick-me-up.
