Oranges are oval to sphere-shaped fruits with leathery, porous skin. Their color ranges from orange to red-orange. Oranges may be confused with other citrus fruits, such as grapefruits and tangerines. However, grapefruits are usually much larger and more yellow than oranges, and tangerines have a more flattened sphere shape than oranges.
Health Benefits of Orange
An orange packs over 170 different phytonutrients and more than 60 flavonoids, many of which have been shown to have anti-inflammatory, anti-tumour and blood clot inhibiting properties, as well as strong anti-oxidant effects.
The combination of the high amount of anti-oxidant (vitamin C) and flavonoids in oranges makes it one of the best fruits in helping to promote optimal health.
Arteriosclerosis: Regularly consuming vitamin C retards the development of hardening of the arteries.
Cancer prevention: A compound in oranges called liminoid, has been found to help fight cancers of the mouth, skin, lung, breast, stomach and colon. The high vitamin C content also acts as a good anti-oxidant that protects cells from damages by free radicals.
Cholesterol: The alkaloid synephrine found under the orange peel can reduce the liver's production of cholesterol. Whereas the anti-oxidant fights oxidative stress that is the main culprit in oxidizing the LDLs in our blood.

Heart disease: A high intake of flavonoids and vitamin C has been known to halve the risk of heart diseases.
High blood pressure: Studies have shown that a flavonoid called hesperidin in oranges can lower high blood pressure.
