A dietary deficiency in __________ triggers anorexia and stunted development?
Show answer Hide answer
Answer: A. zinc
Explanation
Zinc deficiency in growing children leads directly to suppressed appetite and stunted development. Zinc is a vital trace mineral required for cellular metabolism, immune function, and growth. Inadequate dietary zinc impairs normal physiological development and causes clinical anorexia symptoms. Zinc is concentrated in protein-rich foods like meat, shellfish, legumes, and various seeds. Enzyme systems throughout the human body depend on zinc ions to catalyze biochemical reactions. Global nutrition surveys monitor zinc intake to prevent deficiency-related growth stunting.
Public health interventions provide zinc supplements to malnourished children in developing nations. Balanced diets containing adequate trace minerals ensure proper childhood growth and development. Pediatricians monitor growth charts closely to detect nutritional deficiencies and feeding issues early. Iodine deficiency causes goiter and thyroid issues rather than general zinc-related anorexia. Copper deficiency leads to anemia and connective tissue disorders rather than stunted growth. Iron deficiency causes microcytic anemia and fatigue rather than primary appetite loss.
