抗性淀粉种类对大鼠肠道代谢产物和血脂的影响

摘要/Abstract

摘要： 以不同种类抗性淀粉(RS2、RS3、RS4)为研究对象，采用动物实验法，研究其对大鼠肠道代谢产物和血脂的影响。研究结果表明：RS2、RS3、RS4均有控制体质量、降低肠道pH值、增加盲肠组织和盲肠内容物质量、增加盲肠内容物含水量、增加盲肠内容物中短链脂肪酸(SCFA)含量、降低盲肠内容物中氨含量以及调节血脂等方面的生理功能。其中，在控制体质量方面，RS4体质量增加量最小；在调节大鼠肠道代谢产物方面，RS3效果最优；在调节血脂方面，RS3对血清甘油三酯的降低效果最显著，平均降低水平可达30%左右，而RS4对血清胆固醇的调节效果最优。

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
