SFA, saturated fatty acid; MUFA, monounsaturated fatty acid; PUFA, polyunsaturated fatty acid. % peak area calculated from fatty acid methyl esters (FAMEs). Minor fractions of fatty acid profiles not shown. Significantly different from high SFA diet: *P < 0.05, ** P < 0.01, ***P < 0.001, nd, not detectable. Mean ± sd | ||
