Native to Asia, oranges are a hybrid variety that was developed around 2500 BCE. Besides, these citrus fruits are small to medium in size, and are globular, oblate, or oval in shape. In addition, their rind ranges in color from orange, yellow, to green, not to mention that their flesh is juicy and filled with tightly packed juice sacs. Not only are oranges beautifully round and pleasantly juicy, but they're also a good source of several vitamins and minerals, especially vitamin C, thiamin, folate and potassium. Furthermore, they may benefit heart health and help prevent kidney stones. While not rich in iron, oranges may also protect against anemia by increasing your iron absorption.
