Even though strawberries exhibit great nutritional benefits, they are not a complete food.Strawberries provide an excellent source of vitamins C and K, fiber, and flavonoids. They also offer a very good source of vitamin B1, iodine, manganese, and pantothenic acid. Strawberries are also a good source of vitamin B6, folic acid, and biotin. The flavonoids contained in strawberries are responsible for most of their health benefits. Like other berries, strawberries' anthocyanidins are their most powerful flavonoids. Anthocyanidins are also responsible for the vibrant red color of strawberries. Studies have shown that due to Strawberries' unique flavonoid content, they are effective in protecting against inflammation, heart disease, and cancer.
