Dietary insufficiency occurs when an individual does not consume enough essential nutrients, such as vitamins, minerals, proteins, fats, and carbohydrates, to maintain optimal health. This can result from various factors, including poor dietary choices, limited access to food, or specific health conditions that affect nutrient absorption. When dietary insufficiency persists, it can lead to various health issues, such as weakened immunity, fatigue, and developmental problems in children. Addressing this issue often involves improving dietary habits, increasing food variety, and, in some cases, using supplements to ensure adequate intake of necessary nutrients.
