Normal diet (ND)
was prepared by crushing the pellets finely and adding vitamin E as DL-a-tocopherol
(270 mg/kg chow) to the crushed diet. Flaxseed oil (FXO) diet was prepared by
adding 15% flaxseed oil by weight to the normal diet. The diet was stored in airtight
containers. Vitamin E was added in order to meet the increased metabolic requirement
for antioxidants on a diet high in polyunsaturated fatty acids.
