Health benefits of grapes:
Grapes are rich in polyphenolic
phytochemical compound resveratrol. Resveratrol is one of the powerful
anti-oxidant, which has been found to play a protective role against cancers of
colon and prostate, coronary heart disease (CHD), degenerative nerve disease,
Alzheimer's disease and viral/ fungal infections.
Resveratrol reduces stroke risk by altering
the molecular mechanisms in the blood vessels. It does so firstly by reducing
susceptibility of blood vessel damage through decreased activity of angiotensin
(a systemic hormone causing blood vessel constriction that would otherwise
elevate blood pressure) and secondly, through increased production of the
vasodilator substance, nitric oxide (a beneficial compound that causes
relaxation of blood vessels).
Anthocyanins are another class of
polyphenolic anti-oxidants present abundantly in the red grapes. These
phyto-chemicals have been found to have an anti-allergic, anti-inflammatory,
anti-microbial, as well as anti-cancer activity.
Catechins, a type of flavonoid tannin group
of anti-oxidants, found in the white/green varieties have also shown to possess
these health-protective functions.
In addition, the berries are very low in
calories. 100 g fresh grapes just provide 69 calories but zero cholesterol
levels.
Grapes are rich source of micronutrient
minerals like copper, iron and manganese. Copper and manganese are an essential
co-factor of antioxidant enzyme, superoxide dismutase. Iron is especially
concentrated more in raisins. In addition, 100 g of fresh grapes contain about
191 mg of health benefiting electrolyte, potassium.
They are an also good source of vitamin-C,
vitamin A, vitamin K, carotenes, B-complex vitamins such as pyridoxine,
riboflavin, and thiamin.
