Chocolate and strawberries both contain antioxidants. Antioxidants are believed to lower the risk for cancer, and prevent sickness through improved immune function. Strawberries are an excellent source for vitamin C which helps produce collagen and keep our skin looking young. Chocolate is a good source of flavanoids, which are a naturally occuring compound found in plant-based foods. Flavanoids may help to reduce the risk of blood clots and heart disease by expanding arteries.
