ABSTRACT
Objective To investigate the effect of oil with medium-long-chain triacylglycerols on blood lip- id and lipoproteins in hyperlipemic patients. Methods Totally, 112 patients with hypertriglyceridemia were en- rolled and randomly divided into MLCT group (consumed oil with medium-long-chain fatty acids) and LCT group (consumed oil with long-chain fatty acids) (both 25-30 g/d for 8 weeks). Patients in both two groups were also instructed to take exercises. Height and weight were measured at baseline and 8 weeks later. Blood glucose, serum levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), total cholesterols (TC), triglyc- erides (TG), high density lipoprotein cholesterol, low density lipoprotein cholesterol, apolipoprotein Al (ApoAl), ApoB, ApoA II , ApoC2, ApoC3, and ApoE were measured and compared. Results At the end of study, 101 subjects were included. There were 50 subjects left in LCT group and 51 subjects left in MLCT group, respectively. There was no significant difference in weight, ALT, AST, TC, and TG at baseline between two groups (P>0.05). Eight weeks later, weight, serum TG, ApoC2, and ApoC3 were significantly lower and ApoAl level was significantly higher than those at baseline in MLCT group (P < 0.05). At the end of study, the decreases in body weight and blood biochemical variables including TG, ApoB, ApoA II , ApoC2, ApoC3 were significantly much greater in MLCT groups than those in LCT group (P < 0. 05). Conclusion When the diet is reasonably controlled, oil of medium-long-chain triacylglycerols may reduce the concentration of TG and improve the levels of apolipoproteins.
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.
ABSTRACT
Objective To investigate the effects of medium-and long-chain fatty acid triacylglycerols on blood lipid in hyperltriacylglycerolemic subjects. Method A case-control clinical trial was carried out,in which 112 subjects with hypertriacylglycerolemia were enrolled and divided into two groups. These two groups were randomized to long-chain fatty acid triacylglycerol oil(LCT) ,and medium-and long-chain fatty acid triacylglycerol oil(MLCT) . All subjects were requested to ingest fixed energy intake and perform physical activity daily during the whole study. Both of the oils were asked to consume at 25-30g daily for consecutive 8w. Anthropometric measurements and blood biochemical variables were measured at the initial and final time of the study. Results Eleven subjects were excluded from the study because of various reasons. There were 50 and 51 subjects left in LCT and MLCT group,respectively. No difference of sex distribution was noted between two groups. There were also no significant differences in daily intake of energy,protein,fat and carbohydrate,as well as daily physical activity time between two groups at 0,2,4,6 and 8w. The subjects consuming MLCT demonstrated significant decreasesin body weight,BMI,WC,HC,WHR,body fat,body fat % compared with the initial values after 8w. A greater extent of decrease in body weight,BMI,WC,body fat and body fat% was found in MLCT group than in LCT group. The levels of TG,ApoB,ApoAII,ApoC2,ApoC3 in MLCT group were significantly lower than those in LCT group after 8 w,and the extent of decrease in these indicators was much greater in the former than in the latter. Conclusion Consumption of medium-and long-chain fatty acid oil may help to reduce body weight,body fat and concentration of blood triacylglycerol and improve apolipoprotein metabolism in hypertriacylgly cerolemic subjects under an appropriate dietary regime.
