The most common cause of malnutrition is _______.

The most common cause of malnutrition is poverty. This is because poverty limits individuals' access to a variety of nutritious foods that are essential for maintaining a balanced diet. When families or individuals struggle economically, they often cannot afford high-quality foods that provide vital nutrients and may instead rely on cheaper, less nutritious options. This lack of access contributes to both undernutrition and overnutrition issues, as impoverished individuals may find themselves relying on calorie-dense but nutrient-poor foods.

While unawareness of nutritional needs, certain diseases, and crop failures can contribute to malnutrition, they are often secondary to the root issue of poverty. Many people may not be aware of their nutritional requirements, but without the financial means to purchase healthy food, this lack of awareness becomes less significant. Similarly, diseases that affect nutrient absorption can occur, but they are more prevalent in populations already strained by poverty. Crop failures can certainly lead to food shortages, yet they primarily affect regions or communities that are already struggling economically. Thus, poverty stands out as the primary cause of malnutrition on a broader scale.
