The purpose of this study was to examine the effects of dietary indigestible components on mucin secretion in the respective parts of the gastrointestinal tract through their physico-chemical properties. Rats were fed either a control diet or diets containing 5% polystyrene foam (PSF), 5% fructooligosaccharide (FOS), 5% PSF + 5% FOS, or 10% beet fiber for 10 d. Mucins in the small intestine and feces were greater in the PSF, PSF + FOS, and beet fiber groups than in the control and FOS groups. In the cecum, greater mucins were observed in the FOS, PSF + FOS, and beet fiber groups than in the control and PSF groups. None of the dietary treatment was effective on gastric mucins. Cecal mucins were significantly correlated with the cecal pool sizes of total short-chain fatty acids. The correlation between fecal mucins and fecal numbers was also significant. The results suggest that the effect of the bulk-forming property of the dietary indigestible component on mucin secretion is limited to the duct, while fermentability is effective only in the cecum.
