 Powers' contributions to pediatrics included proposing guidelines for the care of premature babies and for the management of infantile diarrhea.He wrote an important paper in 1925 that outlined the principles of infant feeding, arguing that diets should be analyzed by a total caloric intake, including a combination of protein, fat and carbohydrates; these principles were adopted by nutritionists constructing adult diets in World War II.Another popular paper simplified the different options of cow's milk-based infant formulas, which received thousands of international reprint requests.
