Crackers, granola bars, toast, mini bran muffins — these are all healthy snacks, but they're dry. Foods rich in water tend to pack fewer calories into larger servings, meaning you can munch away on slices of bell peppers or apples, baby carrots, or diced melon, and feel full without consuming tons of calories. Another bonus is that these wet snacks keep you feeling full longer, and keep you hydrated, which is good for your skin, your sinuses, and your regularity.
