A nurse must be aware that eating Maize alone may lead onto

Correct option is B

Maize (corn) is deficient in niacin (Vitamin B3) and tryptophan, a precursor for niacin synthesis. Prolonged consumption of maize as a staple without proper processing (e.g., nixtamalization) leads to Pellagra, characterized by the 3 D’s: Dermatitis, Diarrhea, and Dementia. Explanation of each option: • (a) Beri-Beri – Caused by a deficiency of thiamine (Vitamin B1). It is associated with high-carbohydrate diets like polished rice, not maize. • (b) Pellagra – Correct. Niacin deficiency due to maize-based diets causes pellagra, especially in populations that don’t treat corn with alkali (which frees niacin). • (c) Scurvy – Results from Vitamin C deficiency, mostly due to lack of fresh fruits and vegetables, not maize consumption. • (d) Phrynoderma – Caused by Vitamin A or essential fatty acid deficiency, leading to follicular hyperkeratosis. It is not directly related to maize intake.
