Figure 1. Fatty acids present in plasma lipids of male and female rats, after exposure of 30 days to a hyperlipidic cafeteria diet, compared with controls.

The data are the mean ± sem of 6 different animals per group. Pale grey, SFA (saturated fatty acids); cross-patterned blue, MUFA (monounsaturated fatty acids); dash-patterned orange, ω-3 PUFA (polyunsaturated fatty acids); red, ω-6 PUFA; black, trans fatty acids. Statistical significance of the differences between groups (2-way ANOVA): green star, P < 0.05 for diet; purple diamond, P < 0.05 for sex.
