Background Moderate alcohol drinking and marine omega-3 fatty acids (omega 3) have both been associated with low mortality from coronary heart disease (CHD). However, there is little data evaluating the interactions of wine ethanol drinking with omega 3 in CHD patients. Methods The relationships between wine drinking and marine omega 3 were evaluated in a cross-sectional study in patients with CHD participating in a randomized trial testing the effect of a high alpha-linolenic acid (ALA, the main plant omega 3) diet. Daily ethanol intake was calculated as energy and expressed as a percentage of total energy. Plant and marine omega 3 in the diet were carefully evaluated in each patient in both groups. Results Patients were classified according to their habitual consumption of ethanol. Patients in the high ALA group and controls (low ALA group) were analyzed separately. Within each group, there was a progressive increase in marine omega 3 levels with increased alcohol intake, with a level of eicosapentanoic acid (EPA) that increased by 50% (P < .005) and 37% (P < .05) in the low and high ALA groups, respectively. After controlling for potential confounders (including dietary EPA) in a multivariate linear model, the association between wine ethanol and EPA remained significant in the low (P < .001) and high (P < .05) ALA groups. Conclusion In these patients with CHD, moderate wine drinking was associated with higher marine omega 3 concentrations than no alcohol use. Although the data have to be confirmed in large groups, this effect of wine comparable to that of fish may partly explain the protective effects of wine drinking against CHD.
