Vitamin C is the main reason (apart from the fact that blood oranges are just so damn tasty!) that you will want to eat blood oranges. Since blood oranges are citrus fruits, they are a very good source of Vitamin C, also recognized as ascorbic acid. In the past, sailors who had the disease known as scurvy were cured by eating lots of oranges. In terms of health benefits, vitamin C is an antioxidant required for a large number of metabolic functions in the human body, and can aid in repairing tissues and ensuring healthy gums. Another one of the health benefits of Vitamin C is that it aids in healing wounds and shows benefits on the adrenal gland function. Vitamin C is not produced by the human body and therefore must be produced by our diet. Two blood oranges are more than enough to comply with the recommended daily intake of vitamin C.
