  1. Fatty acid content was expressed as a percentage of its integrated chromatogram peak area with respect to the total area of fatty acids that were identified (C14:0, C16:0, C18:0, C20:0, C16:1n-7, C18:1n-9, C18:2n-6, C18:3n-3). Values are expressed as the mean ± S.E.M. of 7 animals per group. ANOVA (p < 0.05): S, sex effect; D, diet effect; SxD, interactive effect; NS, non significant; Student's t-test (p < 0.05): aHF vs Control, bFemale vs Male.
