Notes: SFA: saturated fatty acids, PUFA: polyunsaturated fatty acids, MUFA: monounsaturated fatty acids, HUFA: highly unsaturated fatty acids acids (carbon chain length ≥ C20 with ≥ 3 double bonds), DHA: docosahexaenoic acid, EPA: eicosapentaenoic acid. In the same row, values without superscript mean no significiant difference (P > .05), while values with different superscripts mean statistically significiant difference (P < .05).
