Quantitative fatty acid composition of selected fatty acids in plasma. SFA; saturated fatty acids, MUFA; monounsaturated fatty acids, PUFA; polyunsaturated fatty acids. Data are shown as median and range. High fat (n = 9), FO (n = 5), KO (=6). a = HF vs. FO, p <0.05, b = HF vs. KO, p <0.05, c = FO vs. KO, *= p <0.05, **= p <0.01 and ***= p <0.001. K-W, p indicates the p-value with the Kruskal-Wallace test. FO; fish oil, KO; Krill oil.
