The kiwi berry is an edible, grape-sized fruit similar to a kiwi in taste and appearance. However, instead of a fuzzy brown skin, kiwi berries generally have either a green or purple smooth skin. They are often sweeter than kiwis and can be eaten unpeeled. (Read more on Wikipedia.)
Kiwi berries (like all fruits) are a great source of vitamin C, a natural antioxidant that helps control infections, as well as maintain healthy bones, teeth, and blood vessels.
