Long-term nutritional deficiencies can lead to severe health consequences, affecting physical and mental well-being. Prolonged lack of essential nutrients can result in conditions such as osteoporosis from insufficient calcium, anemia due to iron deficiency, and compromised immune function from inadequate vitamins. Additionally, deficiencies may negatively impact cognitive development, particularly in children, leading to learning difficulties and behavioral issues. Chronic malnutrition can increase the risk of various diseases, shortening lifespan and lowering quality of life. Addressing nutritional deficiencies through a balanced diet or supplementation is critical in promoting and maintaining optimal long-term health and function.
