Fig. 1 (A) Endogenous nitrogen flux in human ileal effluents after ingestion of milk or soy protein. (B) Cumulative dietary nitrogen appearance in human ileal effluents after the ingestion of milk or soy protein. Values are mean ± SD. Asterisks indicate significant differences between groups.

Fig. 2 Flux of endogenous (A) indispensable and (B) dispensable amino acids over time in the human ileal digesta after the ingestion of milk or soy protein. Values are means; standard deviations are omitted for clarity. Note the different scaling of the y-axis in A and B.
