Origin of 'pellagra'
The term 'pellagra' originates from the Italian word 'pellagra', which translates to 'rough skin'. The word combines 'pel' meaning 'skin' and 'agra' meaning 'rough' or 'sore'. Pellagra was first recognized in the early 18th century, with descriptions of its symptoms appearing in medical literature around the time. The link between niacin deficiency and pellagra was firmly established in the early 20th century, notably through the work of American physician Joseph Goldberger, who underscored the significance of diet in preventing this condition. In the United States, pellagra was common in the southern states during the 1930s due to reliance on corn as a staple food. Efforts to combat this disease included fortifying grains with niacin and promoting dietary diversity.
