Abstract

OBJECTIVE:

To investigate effects of medium- and long-chain fatty acid triacylglycerols (MLCT) on body fat and serum lipid in overweight and hypertriglyceridemic subjects.

METHODS:

A double-blind, controlled clinical trial was carried out, in which 112 subjects with hypertriglyceridemia were enrolled and divided into two groups, there were 56 subjects in each group. One group was randomized to consume long-chain fatty acid triacylglycerol (LCT), and the other to MLCT. All volunteers were asked to consume 25 - 30 g test oil daily for consecutive 8 weeks. Anthropometric measurements of body weight, body fat weight, waist circumference(WC), hip circumference(HC), WHR (ratio of WC/HC), total fat weight, subcutaneous fat area, visceral fat area, and serum biochemical variables of glucose, total cholesterols(TC), triglycerides(TG), high density lipoprotein cholesterol (HDL-C) and low density lipoprotein cholesterol (LDL-C)were measured at the initial and final time of the study.

RESULTS:

11 subjects were excluded from the study because of various reasons. Of the 101 included cases, there were 50 (male subject 34, 68.0%) and 51 (male subject 33, 64.7%) subjects left in LCT and MLCT group respectively. The proportion of men in MLCT (64.7%, 33/51) was not significantly different (chi(2) = 0.1227, P > 0.05) compared to those in LCT (68.0%, 34/50). The average age of MLCT was (54.2 +/- 12.5) which was not significantly different (t = 0.39, P > 0.05) compared to those in LCT (53.2 +/- 13.0); Body mass index (BMI) of MLCT was (25.9 +/- 3.3) kg/m(2), which was not significantly different (t = 0.08, P > 0.05) compared to those of LCT (25.9 +/- 2.4) kg/m(2). After consumption of test oil for 8 weeks, extent of decrease in BMI, percent of body fat, subcutaneous fat, serum TG and serum LDL-C in overweight subjects of MLCT were (-0.73 +/- 0.61) kg/m(2), (-1.53 +/- 1.32)%, (-16.29 +/- 19.25) cm(2), (-0.57 +/- 0.86) mmol/L and (-0.05 +/- 0.64) mmol/L respectively, those in overweight subjects of LCT were (-0.19 +/- 0.61) kg/m(2), (-0.58 +/- 1.02)%, (4.69 +/- 19.06) cm(2), (0.65 +/- 1.10) mmol/L and (0.38 +/- 0.58) mmol/L respectively, all of them were significantly different (the value of t were -2.70, -2.43, -3.20, -3.81 and -2.09 respectively, all of P value were less than 0.05).

CONCLUSION:

Consumption of MLCT can reduce body fat weight and serum triacylglycerol and LDL-C in overweight hypertriglyceridemic subjects under an appropriate dietary regime.
