Grapes

Red grapes taste sweeter than white grapes. The sweeter the flavor, the more fructose they contain. All grape varieties consist mainly of water and have a relatively high fructose content.

Green grapes have a somewhat sour taste. Eaten in small quantities, they make for a healthy snack and are almost fat-free.

Black grapes are described as having a slightly sweeter and more tangy taste than red grapes. Black grapes usually contain seeds, although seedless varieties do exist.
