Excerpt from Transactions of the Royal Society of Tropical Medicine and Hygiene, Vol. 14

It is an important fact that in the United States the instances are neither single nor isolated where a dietetic reform in public institutions has resulted in a disappearance of pellagra, just as goldberger demonstrated.

W. H. W1lson,° in Cairo, has contributed importantly to the subject. He regards pellagra as due to a defective protein supply in the diet. His work resulted from careful analyses of (hers known to have produced pellagra, and with others regarded as preventive or curative. He it was who directed attention to the biologic value of protein in such cases. The work of K. Thomas was depended on for the values of protein from various sources. To maintain nitrogenous equilibrium it was found that various substances differed widely. The biological value of vegetable protein, and especially that derived from maize, was found to be less than that of milk or meat protein. Thomas estimated that the amount of tissue repair from 30 grams of meat or milk protein required 100 grams of maize protein to be equalised. It was thought that the inferiority of maize proteins could be explained by the large proportion of zein, which is devoid of both tryptophan and lysine, two amino-acids regarded as essential for animal nutrition. Wilson concluded that the danger from pellagra occurred when the biological value of the protein of the diet was below a certain point.

F. B. 801m8 and his co -workers studied pellagra 1n Egypt among prisoners of war. They found that the level of biological protein could be so exactly determined that they were able to anticipate the disease. Their work pointed strongly to the fact that a rest diet was inadequate to protect against pellagra when the victim was put to work. In their series German prisoners, who supplemented the reasonably good prison diet in various ways, according to the well known German appetite, escaped. But among Ottomans, not so fortunate as to be able to have this supplement, 300 cases of pellagra developed 1n one year. It was found that if the disease was not far advanced it promptly responded to an increase in the biological protein value. These workers emphasised the importance of the part played by diarrhoeal disease in disturbing the protein balance.
