Niacin deficiency was in epidemic proportions in the southern US in

Question

BlackTom AI · Accepted Answer

The question asks about when niacin deficiency was epidemic in the southern United States. To approach this, we’ll evaluate each option in turn.
Option 1: 'around 1776' – This date corresponds to the era of the American Revolution. Historical records of pellagra and niacin deficiency diseases were not identified or described as epidemics at this time, so this choice is not consistent with the well-documented pellagra outbreaks.
Option 2: 'early 1800s' – While nutritional deficiencies were studied in earlier centuries, pellagra tied to niacin deficiency did not emerge as a recognized epidemic specifically in the early 1800s. This makes the option unlikely given the epidemiological history of pellagra.
Option 3: 'early 1900s' – This period aligns with the classical recognition of pellagra, especially in the southern United States, where niacin deficiency became epidemic and was subsequently linked to dietary causes and remedies. This is the historically supported timeframe for the pellagra epidemic.
Option 4: 'early 2000s' – By the early 2000s, pellagra was no longer an epidemic in the U.S.; niacin deficiency is rare in developed countries due to improved nutrition and diverse diets. This makes the option incorrect.
In summary, the third option best matches the historical record of niacin deficiency epidemics in the southern United States, while the other dates do not align with the documented epidemiology and cessation of the pellagra epidemic.
