What is an important etiological factor in kwashiorkor?

Kwashiorkor is primarily associated with a significant dietary protein deficiency. This condition typically arises when a child's diet lacks sufficient protein despite possibly having adequate calorie intake from carbohydrates and fats. Protein is crucial for numerous bodily functions, including growth, tissue repair, and the production of hormones and enzymes. When there is an inadequate intake of protein, the body begins to break down its own muscle and tissue to meet metabolic needs, leading to the symptoms seen in kwashiorkor, such as edema, irritability, and skin changes.

While dietary vitamin deficiencies, carbohydrate deficiencies, and mineral deficiencies can contribute to various health issues, they do not specifically cause kwashiorkor. Thus, understanding the role of protein in nutrition and health is essential for recognizing the etiology of this condition.
