¹Nutrient compositions were calculated from the USDA nutrient database and Reeves [38].
²Total lipid content in diets calculated based on natural occurring lipids and added fat. The SFA : MUFA : PUFA composition of all diets was 1 : 1.2 : 1.
³Total fiber content (11.25%) in all diets based on the amount present from individual dietary components as well as added fiber (cellulose).
