A population primarily consumes corn, which is low in tryptophan. Which physiological outcome results from this dietary constraint?

💡 Explanation

When tryptophan intake is low, the body has less substrate to synthesize niacin, because tryptophan is a precursor to niacin production. Therefore, chronic corn consumption without other niacin sources leads to pellagra, rather than improved blood, bone, or nerve function.
