Which factor does not directly contribute to malnutrition?

Eating a balanced diet is actually a key factor in preventing malnutrition, rather than contributing to it. A balanced diet typically includes a variety of foods that provide essential nutrients needed for the body to function correctly. It encompasses the right proportions of carbohydrates, proteins, fats, vitamins, and minerals, which all play crucial roles in maintaining health. Therefore, individuals who consume a balanced diet are less likely to experience malnutrition because they are meeting their dietary needs.

In contrast, low income, lack of educational resources on nutrition, and over-reliance on processed foods can all be significant contributors to malnutrition. Low income can limit access to nutritious food options, educational gaps can lead to poor dietary choices, and processed foods often lack the necessary nutrients while being high in unhealthy additives. Thus, it's clear that eating a balanced diet supports overall nutritional health.
