INS and metabolic syndrome: Furthermore, it was found by Hartvigsen et al. that the consumption of wheat bread with 24.4% arabinoxylan (11.2 g fiber) resulted in higher insulin iAUC0–120 compared to wheat bread with 13.3% oat β-glucan (13.4 g fiber), and that both of these breads led to higher insulin iAUC0–120 in comparison with rye bread with kernels (12.2 g fiber) in men and postmenopausal women with metabolic syndrome [53].
