Abstract
This study was conducted to investigate the effects of taro powder on body weight and lipid metabolism in high fat and cholesterol fed mice. C57BL6 mice were divided into four groups; normal (normal) diet group, a high fat and cholesterol (HF) diet group, and high fat and cholesterol diet groups with 20% taro powder (HF-taro 20%) and 30% taro powder (HF-taro 30%). After 8 weeks, body weight in the HF group increased to 175% of the normal group, while those of HF-taro 20% and HF-taro 30% group decreased by 12.5 and 14% compared to the HF group. The HF-taro 20% and HF-taro 30% groups had significantly reduced epididymal adipose tissue weight. Plasma triglyceride, total cholesterol, and LDL-cholesterol concentrations were significantly higher in the HF group than those in the normal group, while their amounts were significantly diminished in the HF- taro 20% and HF- taro 30% groups. Furthermore, the leptin and insulin concentrations in blood plasma decreased significantly in the HF-taro 20% and HF-taro 30% groups. Accumulation of triglycerides and cholesterol in the liver was significantly inhibited in the HF- taro 20% and HF-taro 30% groups through liver weights, a blood analysis, and histological findings. These results suggest that taro powder may be an effective material for anti-obesity by reducing plasma triglyceride and cholesterol levels.
