Nutritional deficiencies often stem from a variety of underlying causes, including poor dietary choices, economic factors, and lack of access to nutritious foods. Imbalanced eating patterns and reliance on processed foods can lead to inadequate intake of essential vitamins and minerals. Additionally, specific health conditions, such as malabsorption disorders, can impair nutrient absorption. Education on balanced diets and accessibility to nutritious food options are vital to mitigating these issues.
