Fluorine Balance Studies on Four Infants

Abstract
Fluorine balance studies were carried out on 4 male infants. Each infant was studied during two periods which were each three days in length. In period I the infants ingested milk formulas only and in period II, milk formulas plus Pablum which had been gradually increased in the diet to the level studied. The addition of Pablum to the infants' diets considerably increased the amount of fluorine ingested. Generally, the studies indicated that the fluorine in infants' diets was retained to some extent. The per cent retention appeared in each case greater in period II than in period I and the absolute amounts retained were also higher.
