The grape is one of the oldest fruits to be cultivated going back as far as biblical times. Spanish explorers introduced the fruit to America approximately 300 years ago. Some of the most popular ways in which the fruit is used, is eaten fresh, in preserves or canned in jellies, dried into raisins, and crushed for juice or wine. Although, machines have taken the place of much handwork, table grapes are still harvested by hand in many places. (Wellness Encyclopedia of Food and Nutrition, 1992).

Raisins, or dried grapes, contain only about 15 percent water. For this reason, nutrients and calories are more concentrated in raisins-one cup contains 464 calories!
