According to Medical News Today, 1 cup of green grapes, or about 32 grapes, contains 104 calories, 1.09 grams of protein, 0.24 grams of fat and 1.4 grams of fiber. It also contains 4.8 milligrams of vitamin C, 10 micrograms of vitamin A, 288 milligrams of potassium, 0.54 milligrams of iron and 3 micrograms of folate. Grapes are also high in water content, containing 70 milliliters of fluid per cup.

Medical News Today describes green grapes as nutrient dense, which means they provide a large number of nutrients but few calories. Because they are high in antioxidants, such as lutein and zeaxanthin, they are good for eye health. Grapes also contain the antioxidants polyphenols, which are thought to slow or prevent esophageal, lung, mouth, pharynx, endometrial, pancreatic, prostate and colon cancer. The high content of polyephenols may also reduce the risk of cardiovascular disease by reducing inflammation, platelet build-up and blood pressure.

The potassium in grapes is associated with a reduced risk of stroke, increased muscle mass, preservation of bone mineral density and reduced formation of kidney stones. Potassium is also associated with a reduction in the risk of high blood pressure. The high water content and fiber in grapes help with hydration and regular bowel movements.
