Incremental plasma insulin concentrations for the acute trial (mean ± SE; n = 13). At time 0 the test meal was consumed, which was exactly one hour after ingestion of the control treatment (1 c water) or the peanut or grain bar treatment, each with 1 c water. Incremental plasma insulin did not differ between groups (repeated measures ANOVA, time x group interaction; p = 0.268).
