Malnutrition refers to a condition that occurs when a person's diet does not provide the necessary nutrients for optimal health. This can happen due to insufficient intake of essential vitamins and minerals, leading to deficiencies, or from consuming too many unhealthy foods, resulting in obesity. Malnutrition can affect anyone, but it is particularly common among children and the elderly. The consequences of malnutrition can be serious, impacting physical and mental development, immune function, and overall well-being. Addressing malnutrition often requires a balanced diet that includes a variety of foods, such as fruits, vegetables, whole grains, and proteins, to ensure that individuals receive the nutrients they need for a healthy life.
