The U.S. Department of Agriculture says adults should consume between 1 1/2 and 2 cups of fruit each day. A high intake of produce like fruit may lower your risk of high blood pressure, heart disease, Type 2 diabetes, osteoporosis, cancer, obesity and kidney stones. Grapes, which are rich in dietary fiber, antioxidants and essential vitamins and minerals, are a convenient way to help you get enough. A typical serving of fresh or canned grapes is equivalent to 1 cup, or approximately 32 small seedless grapes.
Vitamins in Thompson Seedless Grapes
Red or green Thompson seedless grapes are the most commonly consumed grape variety in the United States. A 1-cup serving of the fresh grapes contains 22 micrograms of vitamin K, 18 percent of the recommended dietary allowance for men and 24 percent of the intake advised for women. Your body needs vitamin K for proper blood coagulation and to strengthen bones. Thompson seedless grapes are also a source of vitamin B-6, with each serving supplying 10 percent of an adult's RDA.
Vitamins in Slip-Skin Grapes
Slip-skin grapes are a North American variety that, unlike Thompson seedless grapes, have an easily removable peel. These grapes also contain vitamin K and vitamin B-6, though they have a lower concentration than Thompson seedless grapes, with 13.4 micrograms of vitamin K and 0.10 milligram of vitamin B-6 in a 1-cup serving. Slip-skin grapes contain small amounts of other B vitamins, including thiamine and riboflavin. The B family of vitamins is required for energy metabolism and nervous system health.
Vitamins in Muscadine Grapes
Muscadine grapes have a thick peel, usually contain four seeds and are larger than other grape varieties. Because of their size, a serving of muscadines is 10 to 12 grapes. These grapes are an excellent source of riboflavin, with 1.1 milligrams of the vitamin per serving, an amount that supplies all of a woman's daily requirement and 85 percent of a man's. Also known as vitamin B-2, riboflavin aids in the synthesis of red blood cells. Your body also needs riboflavin to use folate and vitamin B-6.
Vitamins in Canned Grapes
According to the USDA, canned grapes have a higher concentration of vitamin K and vitamin B-6 than raw grapes. Every 1-cup serving contains 24 micrograms of vitamin K, or 20 percent of a man's RDA and nearly 27 percent of a woman's. Canned grapes supply 12 percent of an adult's daily required intake of vitamin B-6, with 0.16 milligram of the nutrient per cup. Choose grapes canned in water instead of brands that pack the fruit in heavy syrup for fewer calories and less sugar.
