grapes Nutritional properties

Nutritional properties


  • water
  • simple sugars (glucose and fructose)
  • vitamins (especially C, K and group B)
  • mineral salts (especially copper and potassium)
  • fair percentage of dietary fiber.

In addition, it contains other substances, present in small quantities but important for health:

  • phenolic acids (anthocyanins and flavonols);
  • stilbenes (resveratrol);
  • flavonoids (bioflavonoids).

The concentrations of the individual nutrients vary according to the cultivar, the cultivation conditions and the preservation methods of the fruit.

White, red and black grapes: what's the difference?

White, red and black grapes: what’s the difference?

The main components are the same but, between the white and the black one, the difference is not only in the external appearance and taste.

Different colors correspond to different nutrients .

In fact, green fruits and vegetables are characterized by magnesium and folic acid , particularly useful for regulating energy metabolism and reducing tiredness and fatigue. They also help the functioning of the nervous and muscular systems.

Instead, the characteristic blue-violet color of black grapes indicates a phytocompound with an antioxidant action, anthocyanins, typical substances of all fruit and vegetables of that color.

Finally, red grapes also contain higher amounts of iron than white grapes.

Grapes: with or without peel

It is precisely the peel that is the bearer of resveratrol and polyphenols to the maximum extent , so eating it does not hurt, indeed.

These substances have antioxidant and anticancer properties , reducing the formation of free radicals and preventing the oxidation of bad cholesterol , with great benefits also for the heart .

The only caveat is for those with difficult digestion.

In fact, the grape skin is quite rich in cellulose and could further slow down the digestive process .

Benefits of grapes

Antioxidant, anti-inflammatory and antitumor

The presence of antioxidant substances such as anthocyanins, flavonols and resveratrol constitutes an effective protective shield against the negative effects of free radicals, responsible for the development of diseases linked to aging.

In fact, the antioxidants present in plants are of great importance as possible protective agents that help fight oxidative stress.

Furthermore, anthocyanins are able to ensure good protection from the harmful effects of free radicals on blood vessels, against arthritis and heart disease .

The resveratrol , found in significant concentrations in the skin of the grapes (and red wine), has properties: hypoglycemic, anti-inflammatory, anti-platelet and antiatherosclerotic.

A great deal of research, especially in the last fifteen years, has highlighted the potential ability of resveratrol to interfere with all stages of carcinogenesis . These results underline its relevance in the prevention of cancer diseases.

Keeps the skeletal system healthy

Grapes have a set of minerals that are essential in the formation and maintenance of healthy bones .

Calcium, copper, iron and manganese combine to strengthen the skeletal system and to counteract degenerative diseases such as osteoporosis.

Improve cognitive functions

The polyphenols contained in grapes, thanks to their antioxidant action, seem to have the ability to slow down the aging of neural cells .

Recently some American researchers from Cornell University in New York published a study on the brains of rats treated with antioxidants in the Journal of Agriculture and Food Chemistry . In this case with quercetin , a very abundant antioxidant in grapes.

The study showed that neural cells resisted better the damage induced by their exposure to oxidizing agents responsible for the cellular suffering present in Alzheimer’s.

Thus, this study reinforces the theory that the risk of developing Alzheimer’s disease or other neurodegenerative diseases can be reduced by regularly consuming natural antioxidants .

Improve blood circulation

Grapes are also effective in the clinical and functional manifestations of the venous system (such as hemorrhoids, capillary fragility and venous insufficiency of the lower limbs ), in the treatment of phlebitis and as a natural remedy for bleeding (due to its astringent properties).

Its action on vascular inflammation has also been studied in a work published in Arteriosclerosis Thrombosis and Vascular Biology, which explains how grape juice containing quercetin decreases the presence of superoxide (a known free radical) and of the binder CD 40, clear marker of ongoing inflammation responsible for excessive platelet aggregation and therefore involved in the onset of atherosclerosis .

Protects from diabetes

Scientific studies have highlighted an alleged role of polyphenols in the prevention of some degenerative diseases, especially for the antidiabetic effect they play .

Grapes, which contain large quantities of it, would therefore also play a protective role against diabetes, despite the high content of sugars.

Consistent consumption seems to help regulate insulin and blood sugar levels.

Grapes: vitamin supplement

It constitutes a rich reserve of vitamins B1, B2, B6 (or vitamin PP), C, and K .

Thanks to its high water content (about 80%) and to the presence of substances such as resveratrol and pterostilbene , present in the peel, it would help your body to purify itself .

Be careful, though: before embarking on the grape diet , it’s best to ask your doctor for advice.


At high dosages, it can create some disturbances. In particular, due to the presence of fibers (cellulose) that give rise to fermentation processes, grapes are not recommended for those suffering from gastric ulcer, gastrointestinal diseases and colitis .

Grapes are also not recommended for diabetics . A cluster of grapes of about 2 ounces contains 31 g of sugars divided between fructose and glucose, practically the same quantity contained in 300 g of apples.

Grapes: historical notes

The Vitis vinifera is also known as European vine , although it should be called Eurasian : the area of origin is not well defined, but it was once thought came from the South Caucasus.

For many centuries the main destination of the grapes was winemaking , while direct consumption was marginal and limited to the best and sweetest bunches.

THE first literary references are contained in the Old Testament , which speaks of the Hebron valley (valley of the grapes) as an area where the vine was cultivated as a fruit plant and not for wine.

Today, in the world, cultivation is widespread in over 40 countries, although more than half of world production is concentrated in Europe (especially in Spain, Italy and France).
