Corn has low levels of niacin,and low intake of animal protein would mean that relatively little tryptophan would be available to be converted to niacin;therefore,the population would be at risk for developing pellagra,the niacin deficiency disorder.Scurvy is caused by deficiency of vitamin C.Lack of folate during early pregnancy can lead to spina bifida.Pernicious anemia is caused by lack of intrinsic factor in the stomach to facilitate absorption of vitamin B₁₂.
