A grape is a berry that grows on a vine. Purple grapes can be used for making and grapeseed oil, juice, jam, jelly, grapeseed extract, wine, vinegar, raisins, or eaten raw. Grapes grow in clusters in many different climates.
Yeast is present right on the skin of the grapes, which helped lead to the invention of wine.
One thing most people don’t know about nutritional info on purple grapes is that choosing seedless grapes is to lose many health benefits available through the phytochemicals present in grape seeds. Taking a grapeseed supplement gain the benefit which may be otherwise lost. When making wines, the seed is pressed.
The health benefits of purple grapes and red wines have been written about often. Some research studies have found the following results over and over again:
- Reduction of susceptibility to vascular damage by altering of molecular activity in blood vessels.
- Lowering of angiotensin activity- a systemic hormone that causes constriction of blood vessel which in turn leads to high blood pressure.
Reversatrol (a polyphenol), which is present in the seeds and skin of red grapes, can give a benefit physiologically by increasing the production of nitric oxide, a vasodilator hormone. Reversatrol in purple grapes was also attributed to benefits like, blocking gene expression linked to heart disease, stopping cancer, viral infections, degenerative nerve disorders, and symptoms of Alzheimer’s disease.
