The effect of dietary ABA (20 mg/L drinking water) on blood glucose levels in response to intraperitoneal (IP) glucose tolerance test. After 12 weeks of treatment, animals from the four groups were fasted overnight (12–13 h) and given 2 mg/kg of glucose by IP injection. Blood drops were taken from the tail, and plasma glucose concentration measured at the indicated times. Data are presented as the mean ± SEM. White circles represent rats fed HFD; black circles, HFD-ABA; white triangles, SD; and black triangles, SD-ABA. Data points at 120 min were analyzed using one-way ANOVA followed by post-hoc Newman–Keuls test. *, p < 0.05
