Procyanidins In Red Wine Help You Live Longer
You can read about this study in the journal Nature, November 30 issue.
The researchers also found that levels of procyanidins are not the same in all wines. Wines from southwest France and Sardinia, where it is still made in the traditional way, tend to have higher levels of the compound - in some cases their levels were 10 times as high as wines from elsewhere.
People should bear in mind that the daily glass of wine could have varying degrees of benefit, depending on where it came from. The researchers specifically noticed the higher levels of procyanidins from the Nuoro area in Sardinia and the Gers region, Midi-Pyrenees, south west France. On average, the scientists found those two areas had procyanidin levels five times higher than wines from Spain, South America, the USA and Australia.
Roger Coder, team leader, said \"The endothelial cells which line our arteries are an important site of action for the vascular protective effects of polyphenols. We purified the most biologically active polyphenols and identified them as procyanidins. The traditional production methods used in Sardinia and southwestern France ensure that the beneficial compounds, procyanidins, are efficiently extracted. This may explain the strong association between consumption of traditional tannic wines with overall well-being, reflected in greater longevity.\"
Corder added \"There is a 19th Century expression - A man is only as old as his arteries - which can be taken to mean that those with the healthiest arteries live longer. So it was of great interest to us when we found both in Sardinia and in south-west France that the wines made in these in areas had higher levels of procyanidins.\"
When wine is made in the traditional way, the fermentation period of the grapes lasts three to four weeks, as opposed to the one-week period in more modern ways. The traditional method allows for the full extraction of procyanidins from the skin and seed.
The researchers also found that the Cabernet Sauvignon and the Nebbelio grapes made the wines with the highest levels of procyanidins.
