George Budd (1808-1882) and nutritional deficiency diseases.

As the century drew to a close the orthodox teaching on man's need for food could be expressed in the following manner. There were five proximate principles of foods. Three, proteins, fats and carbohydrates, were organic, and two, salts and water, were inorganic.... It will be observed that this scheme makes no mention of any such food substances as the curative antiscorbutic principle of fresh fruits, in spite of the hundreds of years of experience of the disease. The nutrition experts were so busy at the end of the century amassing quantitative data about the need for protein and calories they seem to have had little or no time for any wider problems."
