Final answer:
An example of protein-related malnutrition is: A) kwashiorkor.
Step-by-step explanation:
Kwashiorkor is a form of protein-related malnutrition characterized primarily by a swollen abdomen. It often occurs in children who are weaned off breast milk and do not receive adequate protein from their subsequent diet. Despite possible adequate energy intake, the lack of protein leads to insufficient amino acids for cellular function and growth, resulting in serious health issues such as skin problems, weak muscles, swollen bellies and feet, and developmental concerns. Kwashiorkor is a serious global health problem, most prevalent in developing countries where access to a diverse diet with sufficient protein is limited.
The correct answer to the question of which is an example of protein-related malnutrition is A) kwashiorkor. This condition is distinct from other nutrient deficiencies, such as rickets (vitamin D), anemia (iron), and scurvy (vitamin C), which are caused by the absence of specific nutrients other than protein. Protein-energy malnutrition (PEM), which encompasses both kwashiorkor and marasmus, represents a spectrum of disease associated with insufficient protein and, sometimes, energy intake.
