Paternal fatty-acid consumption and insulin tolerance test. a Male rats fed a control diet (CO) or a lard-based (LB) or corn oil-based (CB) high-fat diet consumption of dietary fats (saturated fatty acids [SFA], monounsaturated fatty acids [MUFA], and polyunsaturated fatty acids [PUFA]) (n = 20 per group). b Insulin tolerance test (ITT) of the CO-, LB-, and CB-fed male rats (n = 6 per group). Inset: ITT is shown as the AUC. c Fifty-day-old female offspring (n = 6 per group). Inset: ITT is shown as the AUC. Statistically significant difference (p ≤ 0.05) compared with ^aCO and ^bLB, according to analysis of variance followed by a least significant difference test. The data are expressed as mean ± SEM
