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.
