Serum Cholesterol-Decreasing Effect of Heat-Moisture-Treated High-Amylose Cornstarch in Cholesterol-Loaded Rats

抄録

Rats were fed on a diet containing cholesterol (Chol) at a level corresponding to the standard Chol intake in humans, and the influence of heat-moisture-treated high-amylose cornstarch (HHA) on their serum Chol level was investigated. HHA decreased the serum level of Chol in rats fed on the diet containing 0.1% Chol, which corresponds to a Chol intake in humans of 800 mg/d, although the liver levels of Chol increased in these rats. HHA did not influence the fecal excretion of Chol/bile acids. It is possible that the decrease in serum Chol level in the rats fed on the high-Chol diet can be attributed to the promotion of Chol uptake in the liver.
