 reduced this effect in fresh milk. Along with Mildred Fish, he conducted studies between 1914 and 1920 to elucidate the etiology of scurvey by withholding orange juice from institutionalized infants until they developed hemorrhages as a result of the disease; he conducted similar studies to elucidate the etiology of rickets. His work led him to state that the process of food manufacture and preservation should aim to preserve the nutritional value of fresh food in his 1921 Harvey lecture, a concept widely recognised today.

He determined that rickets could be prevented with cod liver oil or exposure to ultraviolet light, and that certain foods could be used to treat rickets after exposure to ultraviolet light. He ascertained that cholesterol
