In the accepted methods of therapy for acne vulgaris, nutrition has hitherto played a subordinate rôle. Usually the carbohydrate intake is restricted, and some attention is paid to the vitamin content. A number of authors (Brocq, Spiethoff, Arning, Brill and von Noorden) advocated bland diets for patients with various dermatoses, chiefly with a view to reducing the intake of table salt, but no general nutritional therapy was proposed until recently. The striking curative results which were obtained in cases of lupus vulgaris with the Gerson and Herrmannsdorfer-Sauerbruch diets focused renewed attention on the influence of the mineral balance on pathologic cutaneous processes.
Since it is known that the skin is the chief salt depot in the body, the belief that table salt may adversely influence such processes received support from the observed effects of the aforementioned diets, which, unlike bland diets, not merely reduce but almost exclude table salt.
