Metabolic Patterns in Preadolescent Children

XII. Effect of Amount and Source of Dietary Protein on Absorption of Iron^1,2,

Department of Human Nutrition, Georgia Experiment Station, Experiment, Georgia

As one segment of a series of metabolic studies with 36 healthy preadolescent girls, the iron content of the diets and feces was determined. Iron absorption was not significantly influenced by protein, riboflavin or niacin content of the diet; however, in one study iron absorption was significantly increased when the daily protein intake was reduced by removal of all milk from the diet. A dietary allowance of at least 12 mg of iron/day is advocated for 7- to 9-year-old girls.

² This study was a phase of the Southern Regional Research Project, Requirements and Utilization of Selected Nutrients by Preadolescent Children, supported in part by funds appropriated to the U. S. Department of Agriculture under the Research and Marketing Act of 1946, and the Hatch Act, as amended. The Human Nutrition Research Division of the Agricultural Research Service was a cooperator in this project.
