title: Acute dietary effects on plasma lipids, lipoproteins and lipolytic enzymes in healthy normal males.
abstract: Diurnal plasma lipids and lipoproteins were studied in twelve healthy young males on corn oil and palm oil diets, respectively. The major triglyceridy. Lecithin-cholesterol acyl transferase, lipoprotein lipase and hepatic triglyceride lipase were also measured. diurnal changes of triglycerides and cholesterol were confined to lipoproteins of d less than 1.006 kg/l. There was a diurnal rise of lecithin-cholesterol acyl transferase activity with corn oil but not with palm oil. Fasting and postprandial postheparin lipoprotein lipase and hepatic triglyceride lipase were similar but there was a significant correlation of postprandial hepatic lipase with postprandial plasma triglycerides on palm oil. Marked diurnal changes of triglyceride fatty acids were observed not only in 'very low density lipoprotein' but also in high-density lipoprotein amounting to approximately one third of total high density lipoprotein triglyceride fatty acids.
