Values are mean ± SD; rats. Day 0: birth; day 90: adulthood; EPAX: EPAX diet; LDL: low density lipoprotein; ISIO: ISIO diet; TNBS: trinitrobenzene sulfonic acid assay; VLDL: very low density lipoprotein. Data were analysed statistically by ANOVA. Significant differences between macrosomic and control rats and between ISIO and EPAX diets at each age were assessed using Student’s test.  and  compared with the control group.  and   compared with the group fed with the ISIO diet.
