Values are means ± SE for groups of 7 rats. Male and female Sprague-Dawley rats were offered diets of different sucrose content [sucrose-free (NS) diet, 66.6% of energy as sucrose (HS) diet, and NS diet + 30% sucrose solution (LS) diet] for 53 or 54 days. FFA, free fatty acid; TG, triglyceride. Values within male or female groups that do not share a common superscript are significantly different (P < 0.05), as determined by 1-way ANOVA and post hoc Tukey’s test.
