Figure 3. Excretion of total sugars in fractions of feces from men fed constant diets of different fiber contents. Data are mean from five men, expressed on basis of stool dry weight. The pooled SEM of all fractions sugar data is 0.13. More sugars were excreted in plant (P) (p < 0.001) and soluble (S) (p < 0.05) fractions with each fiber addition. Daily output of bacterial (B) sugars increased (p < 0.01) only with the first fiber adddition. Significant differences were identified by two-way analysis of variance.
