Fig 3. Changes in plasma glucose and insulin levels during the rice tolerance test.

Levels of plasma glucose (A1, B1) and the area under the curve (AUC) for plasma glucose (A2, B2) during the rice tolerance test at baseline (T0: left graph) and at the end of intervention (T1: right graph) for estimating the postprandial state during the intervention. Levels of plasma insulin and AUC were measured during the rice tolerance test (C1–2, D1–2). BR, brown rice diet group (black circle and box), WR, white rice diet group (white circle and box).
