Is there a difference nutrition wise between green and red grapes? Also, I have type 2 diabetes and take oral medication. I like to eat frozen green grapes, especially in the summer. I know they have sugar, but what do you suggest as a serving size? Getting adequate fruit and vegetable intake is a great way to maintain a healthy weight and reduce risk of disease. The American Cancer Society suggests that we get a minimum of 5 servings of fruits and vegetables a day (with newer recommendations urging people to get 7-9 servings a day!) One serving of grapes would equal approximately 15 grapes. A medium banana, small apple or peach, and approximately 6 strawberries are other serving sizes. One cup of leafy greens, a half of a cup of cooked vegetables, one roma tomato and one ear of corn would be other examples of serving sizes. Most health experts would suggest that you choose red over green grapes. Red grapes get their color from disease fighting antioxidants called flavonoids. A few specific flavonoids have been studied and these include Resveratrol, Catechins, and Quercetin. Studies suggest that these flavonoids can help lower blood pressure and protect HDL (good) cholesterol. Resveratrol has been studied extensively and it may have potential cancer fighting properties. Overall, all types of grapes consumed in moderation can be a healthy addition to your diet. So, even though red grapes may have more potential health benefits, if it is green grapes that you enjoy…eat them and be happy! Login to Favorite
