Strawberries are packed with vitamin C, and they also offer folate (a B vitamin), fiber, and an array of phytochemicals, some of which may help to prevent cancer.
Vitamin C was one of the nutrients used in the Age-Related Eye Disease Study — a major clinical trial sponsored by the National Eye Institute. Vitamin C is an antioxidant, and your body needs it to make connective tissue and for healthy blood vessels, including those found in your eyes.
