説明
The effects of high-amylose cornstarch (HAS) on fecal variables were examined in rats fed diets with graded levels of HAS (2.5-40%). Fecal number, weight, volume, and moisture content were significantly higher in rats fed the 20% and 40% HAS diets than in those fed the cornstarch (CS) diet. Cecal contents were significantly greater in rats fed dietary HAS at a level of 5% or above, but fecal starch excretion was greater only in rats fed the 10%, 20% and 40% HAS diets. The gastrointestinal transit time tended to be shorter in the HAS diet-fed groups. In a separate experiment, higher fecal excretion of nitrogen (p<0.05) and 2, 6-diaminopimelic acid (p=0.098) was observed in rats fed the 20% HAS diet, compared with those fed the CS diet. A further experiment showed a greater cecal pool size of total short-chain fatty acids (SCFA) in rats fed the HAS diets (5-20%) than in those fed the CS diet. However, in rats fed the 20% HAS diet, the cecal pool size of succinate was found to exceed that of total SCFA. These results suggest that HAS moderately increases fecal output, probably by increasing the moisture content of the large bowel.
