Results of a major European study suggest that drinking the occasional glass of wine may protect against coronary heart disease by boosting omega-3 levels.
The IMMIDIET study collected data from 1,604 men and women from south-west London in England, Limburg in Belgium, and Abruzzo in Italy. All participants underwent a comprehensive medical examination, and were asked to fill in a questionnaire about their diet and alcohol consumption.
Results showed that moderate alchohol consumption – one drink a day for women and two for men – was associated with a higher concentration of omega-3 fatty acids in plasma and red blood cells independently of fish intake.
Further analysis of the data to determine whether the effect on omega-3 levels was due to alcohol itself or to other substances present in certain alcoholic drinks, revealed that wine appeared to have the most beneficial effect on omega-3 levels. According to study co-author Michel de Lorgeril, “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.”
