Abstract
The main purpose of these studies was to determine whether the amounts of tin and aluminum that can enter foods during processing and storage are sufficient to affect the utilization of selenium by human subjects. Two 40-day balance studies were conducted. The eight adult males who participated in the first study lost significantly more selenium in their feces when fed a test diet containing 50 mg tin daily than when fed the control diet containing 0.1 mg tin daily. During the first study subjects tended to excrete less selenium in the urine when fed the test diet rather than the control diet. In the second study, the dietary treatments (5 and 125 mg aluminum daily) had no effect on the excretion and apparent retention of selenium by eight adult males.
