. Epidemiological studies have consistently shown an apparent protective effect of moderate alcohol consumption on coronary artery disease (CAD). This has been considered to be due to the rise in the high‐density cholesterol lipoprotein (HDL‐cholesterol). Since the response of the HDL‐subfractions to moderate or heavy dose of alcohol is less clear, we now compared the high‐density lipoprotein cholesterol status between groups consuming different amounts of alcohol. In this population‐based survey serum total high‐density lipoprotein cholesterol and its HDL 2 and HDL 3 subfractions were blindly compared between 264 consecutive middle‐aged men (37 teetotallers, 137 moderate drinkers, 90 heavy drinkers) participating in a voluntary health screening and 104 male alcoholics. Alcohol consumption correlated significantly (P<0.001) with total HDL‐cholesterol, HDL 2 , HDL 3 when all subjects ( n = 368) were included but the correlation disappeared when alcoholics were excluded (n = 264). In comparison with teetotallers, alcoholics had significantly higher total HDL‐cholesterol, HDL 2 and HDL 3 values (P < 0.001). Moderate or heavy intake of alcohol had no effect on HDL 2 but increased the HDL 3 ‐ ‐ fraction. If the protective effect of moderate alcohol consumption is mediated by high‐density lipoprotein, it may not be accounted for by changes in the HDL 2 ‐ ‐ fraction. The observed increases in the concentration of the HDL 3 ‐ ‐ fraction, however, suggest that this subfraction may not be inert with respect to coronary disease and could possibly have a role in the protective effect.
