Abstract: | We investigated the effects of cellulose supplementation on fecal consistency and fecal weight. About 26 women were classified into two groups-normal defecation and constipation groups. All subjects ate the following meals during the experiment: ordinary meals (first week), experimental meals (second week), and experimental meals mixed with 4 g (third week) and 8 g (fourth week) cellulose. The experimental meal contained 16.7 g fiber. Fecal weights, fecal water content, fecal consistency, and defecation frequency were measured during the experimental period. As a result, in the normal defecation group, the mean fecal weight was 222.9 g day(-1) in the first week, and thereafter decreased. Although 20/24 g of fiber intake in the third/fourth week increased the fecal weight to over 150 g, the fecal consistency was still lower than the optimal consistency of around 300 g cm(-2). However, these changes were not observed in the constipated group. |
