Effects of Green Tea-Soybean Paste on Weights and Serum Lipid Profiles in Rats Fed High Fat Diet

摘要

Effects of green tea-soybean paste on weight-changes and serum lipid profiles in rats fed high fat diet were investigated. Sprague-Dawley male rats divided into five groups were fed five different diets for 10 weeks: B group, basal diet H group, highfat-diet containing 0.5% cholesterol +15% lard H-S group, high fat diet containing soybean paste H-0.6GS group, high fat diet containing 0.6% green tea-soybean paste H-4GS group, high fat diet containing 4% green tea-soybean paste. H group showed highestweight gain (p <0.05). Addition of green-tea soybean paste to high-fat diet significantly decreased weight gain, H-4GS group showing highest weight loss (p < 0.05). No significant differences in food efficiency ratio and total food intake were found among groups. Liver weight of H group was highest. Addition of green tea-soybean paste to high fat diet significantly reduced liver weight (p <0.05, Table 2). Concentrations of glucose, uric acid, bilirubin, and total protein were similar among all groups.Mean GPT values of H-4GS group were significantly different from those of H- and H-S groups (p <0.05). H-S, H-0.6GS, and H-4GS groups had significantly lower triglyceride and total cholesterol, and higher HDL than H-group (p <0.05). H-4GS group had significantly lower serum triglyceride than H-0.6GS group (p<0.05).
