Malnutrition refers to deficiencies or excesses in nutrient intake that can lead to undernutrition or overnutrition. Undernutrition is not getting enough nutrients and can cause diseases like goiter, anemia, and rickets. Overnutrition occurs when there is an excessive intake of nutrients leading to issues like overweight and obesity. Malnutrition amongst children is the most severe consequence of food insecurity and can impact growth, development, and health. Preventing malnutrition requires a good healthcare system that provides immunization, treatment, and nutrition education.
