  1. *Values are means ± SD; n = 6. Values in a row not sharing a roman superscript are significantly different at P < 0.05 by Tukey's honestly significantly difference test after a significant F-value (P < 0.05) by repeated measures ANOVA. PUFA, polyunsaturated fatty acids; HUFA, highly unsaturated fatty acids (≥ 20 carbons, ≥ 3 carbon-carbon double bonds).
