    Abstract:
    Long-term (1 y) effects of dietary fat intake on lipoprotein metabolism were determined in 72 healthy women receiving either a 15%-fat diet (n = 34) or usual diet (n = 38). Every three months food records, weight, waist-hip ratio (W:H), percent body fat, fasting plasma triglyceride, cholesterol (C), high-density-lipoprotein cholesterol (HDL-C), HDL2-C, and HDL3-C; apolipoprotein B and A-I, and postheparin lipoprotein lipase (LPL) and hepatic triglyceride lipase activities were determined. In one year, the low-fat-diet (LFD) group had 17% and the non-intervention-diet group had 36% dietary fat. The LFD group showed decreases in cholesterol: 7% TC, 13% low-density lipoprotein (LDL), and 8% HDL. Apolipoprotein A-I, decreased early. Apolipoprotein B did not change. Plasma triglyceride correlated with weight. Percent body fat and W:H correlated with the total and LDL-C. Changes in HDL-C and/or HDL2-C and LPL correlated directly with the changes in dietary fat and inversely with dietary carbohydrate. Changes in total-C or LDL-C correlated with the changes in weight and W:H, but not with the changes in nutrient intake.
