What vitamin is corn deficient in?
Pellagra is common in poor parts of the world, such as Africa and India, where corn (or maize) is a staple food. This is because corn is a poor source of tryptophan and niacin. In the United States, pellagra was prevalent in the early 1900’s in the South where corn played a large role in the diet.
Which deficiency disease is associated with population subsisting mainly on corn?
As people began to travel to other cultures around the world, it became clear that many communities were able to subsist on corn crops without getting pellagra.
Why does pellagra affect people who get much of their carbohydrate from maize?
The reason a maize-based diet predisposes to pellagra is that the proteins of maize are particularly poor in tryptophan, so that a diet in which there are few other sources of protein provides insufficient tryptophan for nicotinamide synthesis.

Corn is a staple food in Mexico, yet they have not suffered from Pellagra. This is because corn does contain niacin, but it is in a bound form that is not usable by the body. When the Mexicans prepare their corn, they use limestone to grind the corn. This releases the niacin and allows the body to utilize it.
