Fruits are a great-tasting way to get vitamins, minerals and fiber and to satisfy your sweet tooth without loading up on calories. And except for a few, such as avocado, coconut and olives, fruits are virtually fat-free.

Fruits contain phytochemicals — a group of compounds that may reduce your risk of chronic diseases, such as heart disease, diabetes and some cancers. Many are also good sources of antioxidants — substances that slow down oxidation, a natural process that leads to cell and tissue damage.

Eating a variety of fruits is vital because different fruits provide different nutrients. For example, oranges and kiwi fruit are good sources of vitamin C. Bananas are a good source of potassium, and apricots are high in vitamin A. So if you rarely venture beyond a few of your favorites, you're missing out on the nutrients and benefits of other fruits.
