1 Values expressed as mean ± SEM (n = 6–8 rats/group). Different superscript letters a, b, and c within the same row indicate significant difference at p < 0.05 by one-way ANOVA followed by Tukey’s test. Abbreviations: MUFAs, monounsaturated fatty acids; PUFAs, polyunsaturated fatty acids; SFAs, saturated fatty acids.
