What we appreciate the grapes? For the divine taste, for their valuable nutritional qualities for the unique healing properties, for what grapes have the ability to slow down the passage of time and prolong youth. This juicy berry is rich in fruit acids, vitamins, essential trace elements and so-called bioactive substances given in mainly polyphenols. That he owes a lot to its unique properties of grapes, and they found it in abundance in their skins, bones, flesh, leaves and vines.
Polyphenols - it is a huge group of plant chemical substances characterized by the presence of more than one phenolic group. Polyphenols are involved in photosynthesis, respiration, plant growth, formation of resistance to bad environment, including the causative agents of infectious diseases are responsible for the pigmentation of plants.
How do polyphenols
Eating berry grapes, drinking a glass of grape juice or a glass of dry wine, we not only have fun calorie restocking trace elements and vitamins, but also enriches your body with polyphenols. Phenolic compounds of grapes and its products (juice and wine) can be divided into two groups - phenolic acids and flavonoids.
Grapes are very rich in phenolic substances, the most common of which are flavonoids such as catechins (catechin, epicatechin) and their derivatives, and colored flavanones (quercetin) and anthocyanins, painted in red and blue colors. Most polyphenols (60-70 percent) is in the bones of grapes, a lot of them in the skins (28-35 percent), the balance being pulp.
Once in our body, polyphenols control and normalize metabolic processes at the cellular level, and, as shown by numerous scientific studies in recent years, their positive impact is difficult to overestimate. Polyphenols can absorb and neutralize free radicals and arrest the chain reactions.
According to many scientists, that free radicals are the scourge of our time, causing many diseases and premature aging. It turns out that the antioxidant properties of polyphenols in four or five times superior to the antioxidant capacity of vitamin C and E.
Not so long ago under the skin of red grapes we have found a very important flavonoid
, The existence of which, according to scientists, largely explains the famous "French paradox" (a low level of cardiovascular disease and cancer at a sufficiently high fat diet and use of wine).
The action of polyphenols on the body versatile and is not limited to the prevention of cardiovascular disease. For example, anthocyanins transkumarovaya acid and provide an antibacterial effect, flavonoids, together with ascorbic acid, involved in the processes of oxidation and reduction, increase elasticity of blood vessels, enhancing their walls, contribute to the accumulation of vitamin C in the liver and adrenal glands. Procyanidins affect the synthesis and release into the blood of many substances that cause inflammation: histamine, prostaglandin, etc., thus it is possible to note a factor action and anti polyphenols and their wound healing properties.
In the production of wine, about 63% of total phenolics of grape seeds and peel pass into the wine, so the wine grape can be considered one of the most effective natural medicines, of course, subject to the optimal dose of its consumption. The largest foreign experts (Gronbaek M., Muntwyler J., Gaziano J., Hart C. et al.) As a result of extensive studies, covering about 300 thousand people came to the unequivocal conclusion: when used daily 150-200 ml dry red wine occurs a significant reduction in the risk of death from cardiovascular disease. In addition, the wine polyphenols have antiradiation effect - derive radionuclides from the body.
Note that the increase in tolerated dose brings benefits to the body, but only gives rise to new problems. But the use of wine therapy, a combination of the procedures carried out on the basis of preparations containing products of wine production (extracts from grapes, grape seed oil, crushed fruit grapes, wine yeast extracts, and the wine itself), at the spa has virtually no contraindications.
Wealth, signed in the vine is now widely used winemakers, pharmacists and beauticians!
Polyphenols and cosmetics
Grapes has long been known for its moisturizing and softening properties. Masks from grape pulp smooth the skin, making it soft and velvety. Not less popular since ancient times grape seed oil. The method of cold pressing in the preparation of oil keeps it all the biologically active substance, determine its anti-oxidant and regenerating properties. In cosmetics grape seed oil is used for the recovery of thin and damaged hair, in lipsticks, creams for the face, body and hands. A owes its miraculous properties of grape cosmetics mainly besides the content of polyphenols in the wine growing products.
Grape polyphenols protect skin from the harmful effects of free radicals, stimulate the production of elastin and collagen fibers that guarantee the elasticity and youthfulness of the skin.
Studies of various scientific groups polyphenols very successfully used beauticians offering more and more cosmetic products using different properties of polyphenols. A striking example of such a commonwealth of science and cosmetics - cosmetics company
, Which was created in the early 90-ies of the last century, Bertrand and Mathilde Thomas, together with Professor Verkoterenom heading an international team to study grape polyphenols. The company has patented a method of extraction and stabilization of grape polyphenols, this method led to the polyphenols stable compound and successfully introduce them to the beauty of the texture. Effective allocation of biological compounds, resveratrol, we also have to research group Caudalie.
Cosmetics containing resveratrol maintain skin elasticity, prevent the loss of elasticity of the skin by stimulating the growth of collagen fibers. In addition, resveratrol is a good UV filter that protects the skin from the negative effects of solar radiation. The production company (which creams, mousses, serums, supplements, etc.) are used all the beneficial properties of polyphenols contained in grape seeds, skins, vine.
But the grape is not only cosmetics Caudalie, many well-known manufacturers have put at the service of the beauty of polyphenols. For example:
- Means this line moisturize, tone and fully protect the skin through the white grape polyphenols, vitamin complex and special;
Clarins Contour Facial Lift
- Tightening and firming face cream, along with other active ingredients contains grape extract;
- A series of cosmetics
Grape by Oriflame
- Which includes a mask-peeling, cleansing gel, day and night creams, and all this with natural grape seed extract of red grapes.
Not only grapes
Grapes - a wonderful berry, grape polyphenols but - only a small part of a large family of polyphenols of plant origin. Food sources rich in polyphenols, it - onions, apples, tea, strawberries, raspberries, blueberries, cranberries, dark beans, cocoa beans, olive oil, some nuts. Almost all known polyphenols are powerful antioxidants, have strong antimutagenic properties, reduces the risk of cardiovascular disease and cancer, prevent premature aging.
In recent years, an increasing number of studies on polyphenols. Even the tale of "rejuvenating apples" found its very scientific basis. Scientists from the British city of Norwich (Food Research Institute), studying the effects of anti-aging apples proved that this property is dependent on the availability of apples polyphenol epicatechin. Apple epicatechin acts on the cardiovascular system, improves blood circulation, maintains the elasticity of blood vessels. British scientists have somehow managed to calculate that regular consumption of apple juice rejuvenates body by an average of 17 years.
Well, let the pill of eternal youth, scientists have not yet found, but we have an opportunity with the help of the ordinary and at the same time affordable and tasty food - grapes, apples, cranberries, chocolate and other sources of polyphenols - renew their youth and to preserve the beauty and Health!
