Abstract

|
This study was performed to investigate the effect of dietary crab shell powder on lipid metabolism in diet induced hyperlipidemic rats. Sixteen male Sprague-Dawley rats were divided into two groups and fed 20% (w/w) crab shell powder supplemented diet for 4 weeks. Energy intake and weight gain were lower in experimental group than in control group. Concentrations of plasma triglyceride, total cholesterol, LDL-cholesterol, and atherogenic index (AI) were decreased and concentration of HDL-cholesterol was increased by crab shell powder supplementation. Concentrations of liver total cholesterol and triglyceride were significantly lower in experimental group. The crab shell decreased triglyceride and cholesterol con- centration in plasma and liver, and increased bile acid excretion in feces. Therefore, the crab shell powder is assumed to exhibit function of chitin or chitosan that effects on lipid metabolism and cholesterol reabsorption.
