A little wine boosts omega-3 in the body: Researchers find a novel mechanism for a healthier heart
Date:12/4/2008

amounts of alcohol, one drink a day for women and two for men, had higher concentration of omega-3 fatty acids in plasma and red blood cells independently of their fish intake".

However important these results appear to be, the best is yet to come. Researchers from Catholic University of Campobasso, in Italy, and from University of Grenoble, in France, turned their attention on the variety of alcoholic beverages consumed in order to see whether the high levels of omega-3 fatty acids detected might be ascribed to alcohol itself or to other substances.

"From our previous studies we know that association between wine drinking and increased concentration of omega-3 fatty acids have been observed says Michel de Lorgeril, from the University of Grenoble, partner of the IMMIDIET project and co-leader of the study - Nevertheless, it was not possible to separate the effects of wine from those of beer or spirits. Our study of 3 populations with different dietary habits and different consumption of alcoholic beverages types allowed us to explore this aspect.".

"Analysis carried out on different alcoholic beverages argues Licia Iacoviello coordinator of the IMMIDIET study at Catholic University of Campobasso - showed that the association between alcohol and omega-3 fatty acids was present in both wine drinkers and beer or spirits drinkers. However, the association was stronger between wine drinking and omega-3 fatty acids levels. This suggests that components of wine other than alcohol is associated with omega-3 fatty acids concentration. We may guess this effect can be ascribed to polyphenols".

Polyphenols are naturally occurring compounds contained in a different variety of food and beverages, such as wine. Due to their strong antioxidant activity, they are able to reduce oxidation processes caused by free radicals.

"We consider these data to be a major finding - de Lorgeril concludes - opening a new window in the field of cardi
