In the United States, pellagra continued to be a huge problem through the mid-20th century. From 1906 to 1940, about three million people contracted it and 100,000 of them died. Most were in the South. … Southerners gradually changed their diets to include fortified foods or those containing niacin. By the 50's, pellagra had almost vanished.—
