Strawberries are packed with vitamins, fiber, and particularly high levels of antioxidants known as polyphenols, strawberries are a sodium-free, fat-free, cholesterol-free, low-calorie food. They are among the top 20 fruits in antioxidant capacity and are a good source of manganese and potassium. Strawberries are low-growing herbaceous plants with a fibrous root system and a crown from which arise basal leaves. The leaves are compound, typically with three leaflets, sawtooth-edged, and usually hairy.
