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.
