Duncan was a subject in a clinical study that was designed to determine the effects of certain diets on health. While participating in the study, he had to live in a special medical unit at the university hospital. He wasn't permitted to eat anything other than the synthetic formula diet provided by the researchers. The formula contained vitamins, choline, minerals, animal protein, purified water, and corn starch.
