Abstract
1) In cases where rats had been raised on whey powder-added or casein-added food containing the arsenite, nutrition was approximately the same as in the milk fed cases.
2) Cheese had no effect on absorption of the arsenite and did not inhibit transfer of the arsenite into organs.
3) Butter and whey powder had no effect on the absorption of arsenite but did inhibit the arsenite from transformation into the brain, as well as inhibiting to some extent movement into the kidney.
4) Casein, like milk, inhibited absorption of the arsenite from transformation into organs.
