Benefits of Grapes
The most well known health benefit of grapes is on the eyes. Grapes are very good for eyes. Grapes are rich in lutein and zeaxanthin, which are responsible for maintaining good eye health as we age. 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).
