Raspberries are composed of more than 85 percent water along with a hefty dose of fiber, which makes them a great fruit to eat if you’re trying to lose weight, lower cholesterol, or manage type 2 diabetes. They are also full of potent antioxidants, including vitamin C and anthocyanins, which can help with arthritis, age-related memory loss, cataracts and other eyesight problems, and maintaining healthy skin and hair.
