Table 1. Changes in serum CPR levels after the consumption of test meals with WR diet or BR diet.

Variables	0 min	60 min	180 min	p value
WR diet serum CPR (ng/mL)	2.51 ± 1.61	5.02 ± 2.73*	7.46 ± 4.94*
BR diet serum CPR (ng/mL)	2.47 ± 1.55	5.63 ± 3.64*	6.05 ± 3.18*

Data are presented as mean ± standard deviation.

CPR, C-peptide immunoreactivity; WR diet, white rice as staple food; BR diet, white rice mixed with 50% β-glucan rich barley as staple food.

^*p < 0.001, before vs. after meal ^†p < 0.05, white rice diet vs. barley diet.
