Effect of triacylglycerols containing medium- and long-chain fatty acids on body fat accumulation in rats

Effect of triacylglycerols containing medium- and long-chain fatty acids (T ML) on body fat accumulation was studied in rats. Male Wistar rats were fed an experimental diet containing 25% soybean oil or TML for 6 weeks. The fo od intake for 6 weeks did not significantly differ between the two diet gro ups. However, the perirenal and mesenteric adipose tissue weight and carcas s fat content were significantly lower in the TML diet group than in the so ybean oil diet group. The epididymal adipose tissue weight and liver triacy lglycerol content did not significantly differ between the two diet groups. The digestibility of dietary fat did not significantly differ between the two diet groups. These results suggest that an intake of TML decreases body fat accumulation compared to an intake of soybean oil in rats.
