Abstract
For the similar purpose with the former report, the amount of the endogenous excretion of minerals, such as copper and iron, from gastrointestinal tract were investigated in this experiment again with 6 healthy adult women.
To ascertain the relation between the amounts of the endogenous mineral excreteion and their intake, 16 days of preliminary period was arranged.
In this preliminary period, the subjects were divided into three groups: the first was fed with the ordinary diet, the second was given high amount of iron peroxide the diet and the third was given 30gr. of dry yeast per day beside the diet respectively.
The average amounts of excretion of mineral per day were measured as follow: 1.0mg. for copper, 1.0mg. for iron, and 15mg. for calcium, for the coresponding intakes of 0.3mg., 1.5mg. and 33mg. of respective elements.
No difference was seen among the 3 groups. due to the difference levels of mineral intakes in the preliminary period.
