In Kwashiorkor, what is primarily inadequate despite a normal caloric intake?

In Kwashiorkor, the primary deficiency is in protein intake, even though caloric intake may appear normal. This condition often arises in areas where the diet consists mainly of carbohydrates, like rice and other starchy foods, which do not provide adequate protein necessary for bodily functions.

Proteins are crucial for many physiological processes, including the creation of enzymes, hormones, and structural components of cells. In the absence of sufficient protein, the body cannot maintain its protein synthesis correctly, leading to symptoms such as edema (swelling due to fluid accumulation), muscle wasting, and immunosuppression.

While other nutrients like fats, carbohydrates, and vitamins are important for overall health, they do not match the critical role of protein in preventing the clinical manifestations seen in Kwashiorkor. The focus on protein deficiency highlights the importance of balanced nutrition that includes adequate protein to sustain health and prevent this specific form of malnutrition.
