Imported from the Ottoman Empire, the sultana is a "white" (pale green), oval seedless grape variety that is typically eaten as a snack food without further processing, not to mention that it is also used in a variety of dishes, such as fruitcake. In addition, the sultana grapes are used to make white wine, in which use they are known for their "sweet blandness”. As a matter of fact, the polyphenols in grapes, such as resveratrol, are thought to have antioxidant, lipid-lowering, and anti-inflammatory actions that may help reduce the risk of cardiovascular disease
