EFFECT OF EDIBLE OIL WITH MEDIUM-LONG-CHAIN FATTY ACIDS ON LIPID METABOLISM IN HYPERTRIGLYCERIDEMIA PATIENTS-DIFFERENT SEX RESPONES / 营养学报

ABSTRACT

Objective To compare the effects of oil with medium-long-chain triacylglycerols (MLCT) on lipid metabolism in hypertriglyceridemic patients with different sex. Method One hundred and one subjects with hypertriglyceridemia were enrolled and divided into two groups. One group consumed oil with MLCT (50 subjects) and another group with long-chain fatty acid triglyceride LCT (51 subjects) for 8 w. No sex difference was noted between two groups. All subjects were informed to consume 25-30g oils daily with fixed energy and perform exercise informed. Anthropometric measurements of body weight,waist circumference (WC) body fat weight, total visceral and subcutaneous fat area in abdomen and blood biochemical variables of aspartate amino- transferase (AST), alanine aminotransferase (ALT), glucose, total cholesterol (TC), triglyceride (TG), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), apolipoprotein A1 (ApoA1), ApoB, ApoAⅡ, ApoC2, ApoC3 and ApoE were measured at initial and final time of the experiment. Results The decreases in body weight, BMI, WC, body fat weight, total and subcutaneous fat area, and blood TG, LDL-C, ApoAⅡ, ApoB, ApoC2, ApoC3, ApoE in male subjects consuming MLCT were much greater than those consuming LCT after 8 w. However, there were no significant differences in these parameters in female subjects between two groups. Conclusion Consumption of oil with MLCT reduces body weight, body fat and blood TG and improves apolipoprotein metabolism in male hypertriacylglycerolemic subjects, but not in female.
