When you have a cold and your immune system is down, you likely reach for a glass of orange juice, right? Oranges—along with other citrus fruits—are always advertised as being high in vitamin C, one of the most prominent vitamins you need in your diet. Vitamin C is a water-soluble vitamin and an antioxidant that can help improve your skin and keep your immune system healthy. According to the Indian Journal of Clinical Biochemistry, vitamin C has also been proven to be beneficial for reducing the risk of developing chronic diseases like cancer, atherosclerosis, diabetes, neurodegenerative disease. And….scurvy.
So naturally, people reach for an orange (or orange juice) when they think they need a little immunity boost of vitamin C. The Recommended Daily Amount (RDA) for vitamin C is around 90 milligrams, with a limit of 2,000 milligrams a day. And while eating an orange does get you closer to your RDA for vitamin C (around 70 milligrams per one medium orange), it doesn’t quite get you there compared to some other popular foods you may know, which easily get your vitamin C RDA in just one serving.
