Effects of alcohol consumption on serum lipoprotein-lipid and apolipoprotein concentrations. Results from an intervention study in healthy subjects.

Serum levels of cholesterol, triglyceride, cholesterol in low density lipoprotein (LDL) and in high density lipoprotein (HDL) and its major subfractions, and of apolipoproteins A-I, A-II and B were measured in 48 healthy men at the end of two 6-week periods in which they consumed normal alcohol (5.0%, v/v) or low alcohol (0.9%, v/v) beer, respectively. Other dietary and behavioural variables were kept constant. Mean levels of triglyceride, HDL cholesterol, HDL2- and HDL3 cholesterol, and apolipoproteins A-I and A-II were higher at the end of the normal compared with the low alcohol periods, and levels of LDL cholesterol were lower. Body weight was greater at the end of the normal alcohol period than at the end of the period of low alcohol but multiple regression analysis suggested that the changes in lipoprotein-lipid and apolipoprotein levels were due primarily to the change in alcohol consumption rather than concomitant changes in body weight. This study confirms an effect of alcohol on both major subfractions of HDL and on its major apolipoproteins.
