Total F = total fat; S.F = saturated fat; M.F. = monounsaturated fat; P.F. = Polyunsaturated fat; D.C = dietary cholesterol
Letters ‘a’ and ‘b’ for each type of fat indicate significant (P<0.05) reductions in mean dietary intake at pre- and post-assessment
** Total fat and total saturated fats measured in grams.
*** Monounsaturated fat, polyunsaturated fat and dietary cholesterol measured in milligrams
