Oranges

Oranges are vitamin and mineral-rich citrus fruit with a sweet, round shape. Oranges are one of the best sources of vitamin C, with one medium orange providing 117% of a person's daily vitamin C requirement.

The following nutrients are also found in a 141g orange: 65 calories; 16.27 g carbohydrate; 3.4 g of fiber; 61 mg of calcium; 14 mg of magnesium; 238 mg of potassium and 63.5 mg of vitamin C. Vitamin C is a potent antioxidant in the human body. This vitamin is also required for the proper functioning of the immune system. It helps the body absorb iron from plant-based diets, which improves immune function. Because the human body cannot produce vitamin C, humans must obtain it from their diet. Oranges are also strong in pectin, a fiber that helps to maintain the colon healthy by binding to chemicals that can cause cancer and removing them from the colon.
