| Abstract: | Semipurified diets containing either 0 or 20% wheat bran were fed ad libitum to male Sprague-Dawley rats for 9 wk. Wheat bran consumption had no effect on vitamin A or E levels in plasma, leukocytes, or liver, nor on vitamin E levels in erythrocytes of these rats after 9 wk of feeding. However, during the study period, values showed transient declines. Both vitamins showed similar declines in leukocytes and livers of the bran-fed rats. Erythrocyte vitamin E levels also were influenced by the wheat bran diet but no erythrocyte vitamin A could be detected. Thus, rats adapt to diets containing high levels of wheat brans, perhaps by metabolic or gastrointestinal modifications. |
