Researchers at Queen Mary University and the University of Glasgow said that red wines from France and Italy are the best to protect the heart, because they contain higher concentrations of procyanidins, antioxidants that contribute to cardiovascular health.
seems that the wine Cannonau of Nuoro, Sardinia, and Madiran wine of Gers, in the foothills the Pyrenees, are particularly rich in polyphenols.
Numerous studies have confirmed that one or 2 glasses of red wine per day have beneficial effects on the heart and moderate drinkers are less likely to suffer from heart disease than teetotalers.
British researchers have identified a particular group of polyphenols, known as oligomeric procyanidins, which would be able to provide the greatest degree of protection to the cells of blood vessels.
The procyanidins suppress production of endothelin-1, a protein that has a vasoconstrictor effect.
the procyanidins, which are the precursors catechin and epicatechin responsible intensity, tone, color and dell'imbrunimento of must / grape juice and wine are part of the family and as a result of grape polyphenols are present in grape juice, and wine.
They are found as single units or monomers, or linked as dimers, trimers, oligomers and polymers, as has been said, have a strong antioxidant activity on free radicals due to the properties of their phenolic groups to donate electrons .
This specific property has a significant therapeutic value and is used to reduce the damage caused by free radicals.
the procyanidins are present in higher concentration in red grapes and, inside the berry, are located in the inner wall of seeds and peel. Through technologies of extraction and processing of organic grapes, you can get grape / grape juices and wines with high contents of these important antioxidants.
