The effects of single cells of carrot or radish on the fecal excretion, mineral absorption rate and structure of small intestine and colon were investigated in rats fed 5% single cell diet for 4 weeks. Carrot contained 28.76% of total dietary fiber and 21.45% of insoluble dietary fiber, and radish contained 23.14% of total dietary fiber and 16.77% of insoluble dietary fiber on a dry weight basis. Total dietary fiber contents of the single cell were 44.68% for carrot, 48.0% for radish. Absorption rates of magnesium were higher in the carrot and radish single cell groups than the other groups. Cellulose significantly increased fecal weight and weight of small intestine. The consumption of cellulose and single cells decreased digestibility of lipid. The length of colon were longer in the carrot and the radish group than the other groups.
