Oranges are a type of low calorie, highly nutritious citrus fruit. As part of a healthful and varied diet, oranges contribute to strong, clear skin and can help lower a person’s risk of many conditions. Oranges are popular due to their natural sweetness, the many different types available, and the diversity of uses. For example, a person can consume them in juices and marmalades, eat them whole, or use zested peel to add a tangy flavor to cakes and desserts. This popular citrus fruit is particularly known for its vitamin C content. However, oranges contain a range of other plant compounds and antioxidants that may reduce inflammation and work against disease.
