Figure 2. Composition of stool from men fed constant diets of different fiber contents. Data are mean ± SEM from five men. Error bars less than one are not visible on the figure. Stool ash concentration was decreased (p < 0.05) by each fiber addition. Stool fat concentration was less (p < 0.01) during the high fiber phase, compared to the low or medium fiber phase. Concentration of stool nitrogen was less (p < 0.05) during the medium and high fiber phases than during the low fiber phase. Significant differences were identified by two-way analysis of variance.
