Grapes are regarded in many cultures as “the queen of fruits," since centuries. These tiny berries are the storehouse of numerous health promoting phyto-nutrients such as poly-phenolic antioxidants, vitamins, and minerals. No wonder why so many of us often include them in our diet, be it in the form of fresh table fruits, dry fruits, juice, or simply in salads.
In structure, each grape berry features semi-translucent flesh encased inside a smooth, thin skin. Some varieties contain edible seeds, while others are seedless. The color of the berry is because of the presence of poly-phenolic pigments in them. Red or purple berries are rich in anthocyanins while white-green berries contain more of tannins, especially, catechin.

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).
