Oranges provide many health benefits. According to HealWithFood.org, oranges provide a high level of antioxidants, lots of vitamin C, limonene, hesperidin, narirutin and beta-cryptoxanthin.

According to HealWithFood.org, the hesperidin found in oranges performs as a strong antioxidant that protects free radicals from damaging the skin. The vitamin C found in oranges supports a healthy heart. For instance, vitamin C reduces the chances of cardiovascular disease by increasing levels of HDL cholesterol, known as "good" cholesterol, lowering blood pressure and stopping fat from turning into plaque in the body's arteries. Vitamin C can also help prevent tumors from growing.
HealWithFood.org states that the skin of a navel orange has especially high amounts of vitamin C. When hesperidin and vitamin C work together, they support healthy-looking skin. The healthy collagen formation helps skin look smooth and youthful. Vitamin C also helps with healthier lungs, which is beneficial for those with asthma.
