Strawberries are a source of vitamin C to strengthen the immune system, fiber to regulate the digestive tract, and vitamin A to maintain healthy organ functioning. The fruits also provide vitamin E to reduce inflammation, potassium to balance fluid levels within the body, copper to develop connective tissues, and other nutrients, including manganese, iron, and iodine. The pigmented skin and flesh contain anthocyanins, natural compounds that give the fruit its coloring and have antioxidant-like properties to protect the cells against the damage caused by free radicals. Historically, Strawberries were used in ancient civilizations such as the Romans to reduce symptoms associated with inflammation, melancholy, fevers, and infections. The leaves and dried fruits were also used in teas in Asia to detox the body. In the 13th century France, Strawberries were thought to soothe upset stomachs and were used topically for skin rashes, blemishes, and complexion.
