History

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

A)Vitamin B3 (Niacin) Deficiency
B)Vitamin A (Retinol) Deficiency
C)Vitamin C (Ascorbic Acid) Deficiency
D)Vitamin D (Calciferol) Deficiency

💡 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.
