<G. A. Wheeler> coauthored a 1915 dietary experiment with <Joseph Goldberger> investigating the cause of <pellagra>. The study followed prisoners in Mississippi after placing them on a restricted diet dominated by cereal foods. Eleven remained in the experiment to its end; the authors reported symptoms sufficient for a diagnosis of <pellagra> in at least six. Other prisoners under observation did not develop comparable evidence of the disease.<Experimental Pellagra in the Human Subject Brought About by a Restricted Diet by Joseph Goldberger and G. A. Wheeler>[printed pages 3336–3339, Experiment, Controls and Results]{ref}
The comparison mattered because it changed food intake while observing people in the same broad setting. The findings supported a dietary explanation without identifying the particular missing nutrient. They should not be read as a population-wide disease probability: a small, selected group subjected to a particular intervention answers a narrower question. The report also records that participation followed an offer of a pardon, which is essential context for interpreting its use of the word “volunteer”.<Experimental Pellagra in the Human Subject Brought About by a Restricted Diet by Joseph Goldberger and G.
