Abstract/OtherAbstract:
The effects of varying polyunsaturated/saturated (P/S) fat ratios on the plasma levels of lipids, lipoproteins, and apolipoprotein A-I were assessed in six normal healthy subjects (three males, three females) with a particular focus on the P/S ratio which would offer optimal concentrations of both low-(LDL) and high-density lipoproteins (HDL). The isocaloric experimental diets contained 40% of calories as carbohydrate, 40% fat, and 20% protein; dietary cholesterol was 400 mg/day. The P/S ratio for the diets was 0.4, 1.0, or 2.0. Each diet was sequentially consumed for periods of 2 wk each. At the end of each 2-wk study period, plasma lipid, apolipoprotein A-I, and LDL and HDL cholesterol concentrations were determined; HDL were fractionated by zonal ultracentrifugation and lipid and protein composition determined. Compared to the P/S = 0.4 diet, mean plasma total cholesterol fell by approximately 6 and 12% on the P/S = 1.0 or P/S = 2.0 diets, respectively; plasma concentrations of LDL-cholesterol, HDL-cholesterol, and apolipoprotein A-I were also decreased on the polyunsaturated fat diets. The mean +/- SEM concentration (mg/dl) of HDL-cholesterol was 49.0 +/- 5.2 (P/S = 0.4), 44.0 +/- 3.8, (P/S = 1.0) and 41.0 +/- 3.7 (P/S = 2.0). As a result of a reduction in both LDL- and HDL-cholesterol on the polyunsaturate-rich diets, the ratios of HDL-cholesterol to plasma total cholesterol and HDL- to LDL-cholesterol were not significantly changed on the three diets.(ABSTRACT TRUNCATED AT 250 WORDS)
