Long valued in hot climates as a refreshing, energy-boosting food, grapes were traditionally used to treat conditions like arthritis and rheumatism. They are known too for their diuretic effects and have been said by traditional healers to do everything from cleanse, strengthen, and rejuvenate the body.
The sweetness of grapes come from their high sugar content with about 15-25% of their calories coming from glucose and the fruit sugar called fructose.
