Grapes are a source of vitamins, with each cup providing 13.4 micrograms of vitamin K, or 17 percent of the daily value; 3.7 milligrams of vitamin C and 0.09 milligrams of thiamine, or six percent of the daily value for each of the latter two nutrients; and 0.1 milligrams of vitamin B-6, or five percent of the DV.hile red seedless grapes aren't a great source of minerals, they do provide 176 milligrams of potassium, or five percent of the DV, per one-cup serving, as well as smaller amounts of magnesium, zinc, iron, calcium and phosphorus.
Researchers analyzed the diets of more than 21,800 children and adults using data from the 2003-2008 National Health and Nutrition Examination Surveys (NHANES) and found that consumers of grapes and grape products had increased intakes of total and whole fruit, as well as dietary fiber, calcium, magnesium, potassium and vitamins A, C, and B6, versus nonconsumers.
