Raspberries are a great source of fiber—some of it soluble in the form of pectin, which helps lower cholesterol. Raspberries are super high in fiber; one cup of raspberries has 8 grams (women need about 25 grams a day and men, about 35). Raspberries are also an excellent source of vitamin C. The deep red color of this luscious fruit is what makes raspberries a true superfood. The red hue is a giveaway that these small jewels are filled with disease-fighting flavonoids. Out of all the different fruits, it is berries that come out highest in the chemical category of flavonoids called anthocyanins. Black raspberries, for example, are the leader and can contain up to 100 milligrams of anthocyanins per ounce.
