  • Data are mean SE of 9 normal and 9 overweight women. Overall ANOVA: group, P = 0.8690; treatment, P = 0.248; group by treatment, P < 0.089; time, P < 0.0001; group by time P = 0.746; treatment by time, P < 0.016; group by treatment by time, P = 0.999. Means with different symbols within a column are significantly different (P < 0.05). Low, medium, and high β-glucan intake averaged 0.3, 0.9, and 3.7 g/meal, respectively. Low, mid, and high resistant starch averaged 0.9, 3.4, and 6.5 g/meal, respectively. RS, resistant starch.
