  1. Data are expressed as mean ± SE; n = 5; SFA, saturated fatty acids; MUFA, monounsaturated fatty acids; PUFA, polyunsaturated fatty acids; n6/n3, ratio of omega-6 to omega-3 fatty acids; C, number of carbon atoms in the fatty acid structure; c, cis; t, trans fatty acid; C10:1n1c-C11:0 and C18:1n3c + C19:0 were unresolved fatty acids, i.e., they were not separated during analysis and thus quantified together
