Since 1896 about twenty-five papers have dealt with the subject, the most valuable being those of Pereira da Silva (1905) and Manuel Ferreira (1927). No country-wide statistics of the prevalence are available, but all authors agree that pellagra is widespread in all the maize-growing districts of Portugal. The purpose of the present work was to study the disease, using some of the recent methods for the appraisal of nutritional status.engjournal article10.1017/S00221724000193311469-4409
