  • Data are mean SE of 9 normal and 9 overweight women. Overall ANOVA: group, P < 0.017; treatment, P < 0.01; group by treatment P < 0.001; time, P < 0.0001; treatment by time, P < 0.040; group by time, P = 0.274; group by treatment by time, P = 0.875. Means with different symbols within a column are significantly different based on log-transformed evaluation (P < 0.05). Means within the group (control and overweight) columns with different symbols are significantly different. Low, medium, and high β-glucan intake averaged 0.3, 0.9, and 3.7 g/meal, respectively. Low, mid, and high resistant starch (RS) averaged 0.9, 3.4, and 6.5 g/meal, respectively. RS, resistant starch.
