Incremental serum glucose for the acute trial (mean ± SE; n = 15). 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 glucose curves differed significantly (repeated measures ANOVA, time x group interaction; p = 0.023). The incremental area-under-curve for 0–120 minutes did not differ by treatment (see inset; p = 0.901). * glucose excursion for grain bar significantly greater than that for peanut or control (p < 0.001). ** glucose excursion for control significantly greater than that for peanut or grain bar (p < 0.05).
