Marine n-3 Fatty Acids, Wine Intake and Heart Rate Variability
This article looks at the protective effect of wine and omega-3 fatty acids from fish on sudden cardiac death. A protective effect was shown with the omega-3 fatty acids, but not with wine. This study did not differentiate types of wine and that may be the reason why no protective effect was seen. I firmly believe that alcohol has little beneficial effect on the heart, but the coloring in red wine is what provides the protective effect seen in previous studies, not the alcohol. The substance resveratrol, found in the skin of grapes and in peanuts, is the compound believed to confer these positive effects.
