Values are means ± SEM for n = 16 subjects. The Control preload was 200 mL water; the oat β-glucan preloads (MW1, MW2, MW3, MW4, OP1 and OP2) were added to 200 mL water. Preloads were taken 2–3 min before consuming ~113 g white bread. * Significantly different from the Control by Dunnett’s test for two-tailed p < 0.05. ** Significance of main effect of treatment by ANOVA.
