Grapes have many health promoting nutrients, including antioxidants, vitamins and minerals. They contain a compound called resveratrol, which is an anti-oxidant that helps protect against cancer and stroke. Grapes are a good source of vitamin C, vitamin A, vitamin K, and B-complex vitamins such as pyridoxine, riboflavin, and thiamin.
Grapes are a good source of copper, iron and manganese. They are low in calories and have no cholesterol. Before eating grapes, rinse them with cold water to remove any pesticide residues and dirt. Grapes tend to spoil quickly and ferment at room temperature. They should be stored in the refrigerator.
