The nutritional benefits of grapes are similar to those found in other berries. To receive the most nutrients from grapes, it’s recommended that the seeds are also consumed. Grapes are a very good source of manganese and are also a good source of thiamin,vitamin B6, riboflavin, vitamin C, and potassium.
They are an excellent source of health promoting flavonoids. Usually, the stronger the color of the grape, the higher the concentration of flavonoids. Grape seed extracts are rich in flavonoids known as procyanidolic oligomers, and have been widely used in treating varicose veins and other venous disorders. These flavonoids are very powerful antioxidants and have been shown to reverse atherosclerosis. In France grapes and grape products, such as wine, are consumed far more than they are in America. Studies have shown that even though the French eat a diet high in saturated fats and cholesterol they have a lower risk of heart disease than Americans.
