Values are means ± s.e.m., N=7 in all cases.

CO, canola oil; PO, palm oil; FO, fish oil; FA, fatty acids; SFA, saturated fatty acids; MUFA, monounsaturated fatty acids; PUFA, polyunsaturated fatty acids, n-3/n-6, ratio of total n-3 to total n-6 PUFA.

Dissimilar letters indicate significant differences (P<0.05)between dietary treatments for that fatty acid fraction (polar or neutral).
