High density lipoprotein concentrations after cessation of smoking: the importance of alterations in diet.
Cessation of smoking is followed by a rapid rise in plasma HDL concentrations. An earlier study has demonstrated a significant relationship between the increase in HDL concentrations and spontaneous changes in food intake, specifically an increased fat intake. In this investigation we have dissociated the effects of cessation of smoking as such from those of dietary alterations by monitoring plasma lipid and lipoprotein concentrations after cessation of smoking in 12 subjects whose diet was kept constant during an initial 2-week control period and during 2 weeks following cessation of smoking. Under these conditions plasma HDL-cholesterol levels did not increase significantly (1.01 +/- 0.26 mmol/l (mean +/- SD) before and 1.04 +/- 0.27 mmol/l after cessation of smoking). Similarly, no significant alterations were recorded for other plasma lipid or lipoprotein concentrations. Activities of lipoprotein lipase and hepatic lipase were unchanged throughout the study. These results suggest that the marked rise in HDL concentrations after stopping smoking is largely related to spontaneous changes in dietary habits which occur upon cessation of smoking.
