Time to pick grapes, … or about advantage of polyphenols

Polyphenols are a huge group of the vegetable chemical compounds which are characterized by existence more than one phenolic group. Polyphenols participate in photosynthesis, breath, growth of plants, formation of resistance to bad ecology, including to causative agents of infectious diseases, are responsible for pigmentation of plants.

As polyphenols work
Eating grapes berry, drinking a glass of grape juice or a glass of dry grape wine, we not only derive pleasure, calories, we resupply minerals and vitamins, but also we enrich the organism with polyphenols. Phenolic connections of grapes and products from it (juice and wine) can be divided conditionally into two groups - fenolokislota and flavonoids.

Grapes are extremely rich phenolic to substances, the most widespread of them are such flavonoids as catechins (catechin, epikatekhin) both their derivatives and the painted flavanona (quercetin) and the antotsiana painted in red and blue colors. Most of all polyphenols (60-70 percent) are in grape seeds, it is a lot of them and in a thin skin (28-35 percent), the rest is the share of pulp.

Getting to our organism, polyphenols control and normalize processes of a metabolism at the cellular level, and as show numerous scientific research of the last years, it is difficult to overestimate their positive impact. Free radicals can absorb and neutralize polyphenols and stop chain reactions.

According to opinion of many scientists, free radicals are a present scourge, causing numerous diseases and presenilation. It appears, antioxidant properties of polyphenols four times or five times are surpassed by the antioxidant potential of C and E vitamins.

Not so long ago under a thin skin of red grapes found very important flavonoid resveratrol by which availability, according to scientists, generally and the well-known "French paradox" is explained (low level of cardiovascular and oncological diseases at rather fat diet and big consumption of wine).

Effect of polyphenols on an organism is multilateral and is not limited to prevention of cardiovascular diseases. So, for example, antotsiana and transkumarovy acid provide antibacterial action, flavonoids, together with ascorbic acid, participate in processes of oxidation and restoration, increase elasticity of blood vessels, strengthening their walls, promote accumulation of vitamin C in a liver and adrenal glands. Protsianidina influence synthesis and emission in blood of many substances causing inflammation: histamines, prostaglandins, etc., thus it is possible to note also an antiallergic factor of effect of polyphenols and also their wound healing properties.

By production of grape wine, about 63% of all phenolic substances of grape seeds and a thin skin pass into wine therefore grape wine can be considered one of the most effective natural drugs, of course on condition of observance of an optimum dose of its consumption. The largest foreign experts (Gronbaek M., Muntwyler J., Gaziano J., Hart C., etc.) as a result of the large-scale researches which captured about 300 thousand people came to an unambiguous conclusion: at the use daily of 150-200 ml of dry red wine there is a reliable reduction of risk of death from cardiovascular diseases. Besides, polyphenols of grape wine have antibeam effect - bring radionukleida out of an organism.

It is necessary to consider that increase in an admissible dose does not bring benefit to an organism but only leads to emergence of new problems. And here use of a vinoterapiya, combination of the procedures which are carried out on the basis of the medicines containing vinoproizvodstvo products (extracts from grapes, oils of grape seeds, the crushed fruits of grapes, extracts of wine yeast and the wine), in Day spa has practically no contraindications.

The wealth concluded in a grapevine is widely used now by wine makers, druggists and cosmetologists!

Polyphenols and cosmetics
Grapes are known for the moistening and softening properties long ago. Masks from grape pulp smooth skin, do it gentle and velvety. Grape oil enjoys not smaller popularity for a long time. The method of cold pressing when receiving oil keeps in is mute all necessary biologically active agents defining it antioxidant and regenerating properties. In cosmetics grape seeds oil is applied to improvement of the thin and injured hair, in lipsticks, face, body and hands creams. And grape cosmetics generally besides is obliged by the wonderful properties to contents in products of wine growing of polyphenols.

Polyphenols of grapes provide protection of skin against adverse effect of free radicals, stimulate production of the fibers of elastin and collagen guaranteeing elasticity and youth of skin.

Researches of various scientific groups on polyphenols are quite successfully used by the cosmetologists offering everything new and new cosmetics of the polyphenols using various properties. A striking example of such commonwealth of science and cosmetology – cosmetic Caudalie which was created in the early nineties the last century by Bertrán and Matilda Thomas together with professor Verkoteren heading the international group on a research of grape polyphenols. The firm patented a method of extraction and stabilization of grape polyphenols, this method allowed to make polyphenols steady connection and with success to enter them into cosmetic textures. To allocation of effective biological connection, resveratrol we are also obliged to the Caudalie research group.

The cosmetics containing resveratrol maintain elasticity of skin, interfere with loss of elasticity of an integument, stimulating growth of collagenic fibers. Besides, resveratrol is the good ultra-violet filter protecting skin from negative impact of solar radiation. In products of firm (and it is creams, mousses, serums, dietary supplements, etc.) all useful properties of the polyphenols which are contained in grape seed, a thin skin, a rod are used.

But grape cosmetics it not only Caudalie, many famous producers placed polyphenols at service to beauty. For example:

- Vinefit Lancôme — means of this line humidify, tone up and completely protect skin thanks to polyphenols of white grapes, and a special vitamin complex;
- Clarins Contour Facial Lift is the strengthening and tightening face cream, along with other active components grapes contain extract;
- Grape cosmetics series from Oriflame – where the mask peeling, the cleaning gel, day and night creams, and all this with natural extract of grape seeds of red grapes enter.

Not only grapes
Grapes – wonderful berry, but grapes polyphenols - only a small part of big family of polyphenols of plant origin. The food sources rich with polyphenols, it is onions, apples, tea, strawberry, raspberry, bilberry, a cranberry, dark haricot, cocoa beans, olive oil, some nuts. Practically all known polyphenols are powerful antioxidants, have strong anti-mutagen properties, reduce risk of cardiovascular diseases and oncological diseases, warn presenilation.

Recently there are more and more researches, to the devoted polyphenols. Even the tale of "rejuvenating apples" found the quite scientific justification. Scientists from the British city of Norich (Institute of a research of food), studying the rejuvenating influence of apples, proved that this property depends on existence in apples of polyphenol of an epikatekhin. Apple epikatekhin affects a cardiovascular system, improves blood circulation, maintains elasticity of blood vessels. The British scientists somehow managed to count that regular consumption of apple juice rejuvenates an organism on average for 17 years.

Well, let scientists did not find a tablet of eternal youth yet, but we have an opportunity by means of usual and at the same time available and tasty food – grapes, apples, a cranberry, chocolate and other sources of polyphenols, – to prolong the youth and to keep beauty and health!
