Effects of Different Types of Resistant Starch on Intestinal Metabolites and Serum Lipids in Rats

Abstract

Abstract: Rats were fed different types of resistant starch (RS) to study the effect of RS on intestinal metabolites and serum lipids. The results showed that RS2, RS3 and RS4 had physiological functions to reduce body weight, lower intestinal pH, increase cecum tissue weight, the weight, moisture content, short-chain fatty acid content and ammonia content of the cecal contents, and regulate blood lipid level. RS4 could result in the smallest body weight gain and showed the greatest serum cholesterol-reducing effect. RS3 had the best regulatory effect on intestinal metabolites and was the most effective in lowering serum triacylglycerol (by approximately 30% at average).

Key words: resistant starch, rats, intestinal metabolites, serum lipids
