Grapes and red wine is considered to be responsible for the famous “French paradox”, with indicates a small percentage of infarction in France despite the high percentage of saturated fats used in food (pork and beef). Unlike them, Germans who principally consume beer, and same nutrition, are not protected from undesired cardiac complications. This is explained by the regular use of red wine, which is rich in polyphenols, flavonoids and proanthocyanidins. Mediterranean diet is rich in flavonoids and polyphenols (grapes and other fruits and vegetables, wine, olive oil – unsaturated fatty acids, whole grain – integrated products, fish).
Grape seed extract contains concentrated most efficient substances from grapes that protect blood vessels from damage, strengthen capillaries, prevent fat oxidation and myocardial heart muscle. Also, grape seed extract stabilizes venous blood vessels and reduces the risk of developing varicose veins. Grape seed reduces atherosclerotic plaques – buildup fats in the walls of blood vessels and contributes to “cleaning the blood vessels”. It reduces the risk of damage to the ocular structures, as well as the possibility of developing macular degeneration and cataracts.
Grape diets are used for detoxification, i.e. purification of the whole body.
How does a grape seed act?
Grape seed extract has the following effects:
- Antioxidant – prevents cell damage caused under the influence of “free radicals”, radiation, chemicals
- Protects heart and blood vessels, prevents atherosclerosis (buildup of fats in the blood vessels walls, which narrowing the blood vessels)
- Prevents the oxidation of fats, especially LDL “bad cholesterol”
- Reduces the possibility of infarction
- Stabilize the weakened blood vessels in varicose veins, reduces swelling and inflammation
- Reduces the damage to ocular structures – macular degeneration and cataracts
- Control of diabetes and diabetes complications
What does scientific research say?
Studies confirm that chronic use of red grape and its products reduces the incidence of heart disease and blood vessels. Impact on reducing the fats level in the blood and prevents clogging of blood vessels, i.e. formation of thrombus. According to preliminary results of grape seed extract does not affect the blood pressure. After some research, the ingredients of grape seed favorably influence with the vision problems.
Pigments proanthocyanidins are giving color to the grapes, and are responsible for stronger antioxidant effect of black and red grapes in relation to white. It is believed that red wine contains 10 times more flavonoids than white wine. Grape seed extract is an antioxidant – prevents damage to the body cells, prevents oxidation of fats and blood cells from sticking together – thrombus. These effects have a beneficial effect on preventing the development of heart disease and atherosclerosis – clogging of blood vessels.
According to some research, grape seed extract shows better protective effect on cells in combination of vitamins E and C. Proanthocyanidins may protect normal cells from damage caused by cigarette and chemotherapy. Their use in reducing the damage caused as a result of an overdose of some remedies was also investigated. Grape seeds ingredients prevent the function of enzymes that destroy the collagen, elastin, hyaluronic acid and other tissue structures. According to the result of a German research, grape extract compared to placebo after 6 weeks of therapy, showed a decrease in swelling of legs, pain and subjective feeling of heavy legs in patients with chronic venous insufficiency.
Grape seed extract is several times more powerful antioxidant than vitamins C and E.
In which cases grape seed should not be used?
Grapes should not be used by diabetics due to increased sugar contents.
Although years before red wine is in advantage, due to presence of proanthocyanidins – pigments which have a very protective effect on the heart and blood vessels, some research shows that white wine have a good antioxidant properties. It is not recommended more than 2 glasses of wine daily.
