Values are expressed as mean ± standard deviation (mg/100 mg of total FA), n = 10 rats/group. Abbreviations: FA, fatty acid; NS, not significant; ND, non-detected; SAT, saturated fatty acids; MUFA, monounsaturated fatty acids; PUFA, polyunsaturated fatty acids. p-value was calculated by the one-way analysis of variance followed by the Scheffé post hoc test. The level of statistical significance was set at p-value < 0.05. a vs. coconut, b vs. soybean, c vs. EPA/DHA 1:1.
