The scientific journal Nature, rewards Sardinian wines through a search William Harvey Institute in London which shows how the Cannonau Sardinian, namely the one coming from the vineyards of Barbagia, reducing the risk of cardiovascular disease, contribute to the long life.
This research has established that the Sardinian Cannonau, prince of wines of Sardinia, has a variety of polyphenols, substances with high antioxidant content, crucial to the fight against cholesterol and atherosclerosis, between 5 and 10 times higher than the fees Australian wines, South African and American.
Only in a region of France (Gers), we found the same concentration of pigments and tannins in the wine and the corresponding longevity of its inhabitants.
The method of production and cultivation, but especially the quality of grapes, are the ingredients of segreto di tali benefici.

Abstract dell'articolo
Oenology: Red wine procyanidins and vascular health".
"Regular, moderate consumption of red wine is linked to a reduced risk of coronary heart disease and to lower overall mortality, but the relative contribution of wine's alcohol and polyphenol components to these effects is unclear. Here we identify procyanidins as the principal vasoactive polyphenols in red wine and show that they are present at higher concentrations in wines from areas of southwestern France and Sardinia, where traditional production methods ensure that these compounds are efficiently extracted during vinification. These regions also happen to be associated with increased longevity in the population. "
