This study was undertaken to determine whether there is any nutritional difference, as shown by increases in height and weight in significantly large groups of children, when the source of supplementary table fat in their diets is vegetable (margarine) rather than animal (butter).

For a number of years there has been some controversy among nutritionists and other workers in the field of fat nutrition regarding the relative merits of animal and vegetable fats in the human diet. A great deal of experimentation has been carried out, the laboratory rat being used, in the main, as the experimental animal.

Little experimental work has been done in fat nutrition, however, among human subjects. For that reason, the present study was decided on. To insure valid results, examinations of the 267 children (white) included in this study were made for a period of two years.
