Abstract
To clarify the effect of vitamin A deficiency on iron, zinc, and copper status in different tissues, three groups of rats were fed two types of synthetic diets for 52 d. Group one, which was fed a vitamin A-deficient diet, showed severe signs of vitamin A deficiency. Groups two (fed restricted amount, pair-fed with group one), and three (fed diet ad libitum) were fed a control diet. After said period of feeding, iron, zinc, and copper were measured in different tissues. Significant changes observed when the groups were compared are summarized below:
