Kiwi

This fuzzy little fruit has about 65 milligrams of vitamin C per servingnearly as much as an orange. Its also rich in potassium and copper and contains more fiber per ounce than a banana which makes it a good aid to digestion. (In one study eating two kiwis a day for one month lessened constipation in people with irritable bowel syndrome.) Kiwis are slightly tart. Theyre delicious by themselves but if you prefer a sweeter flavor try mixing them with strawberries and bananas in a smoothie or fruit salad.
