Which nutritional deficiency arises from maize-dependent pre-Columbian diets with limited nixtamalization?

💡 Explanation

Pellagra results from niacin deficiency because nixtamalization releases bound niacin by alkaline hydrolysis from the complex carbohydrates, therefore readily available for absorption, rather than being excreted; unprocessed maize exacerbates deficiency.
