Essential vitamins and minerals in the diet are vital to boost immunity and healthy development. Vitamin A, zinc, iron and iodine deficiencies are primary public health concerns. About 2 billion people are affected by inadequate iodine nutrition worldwide. More than one third of preschool-age children globally are vitamin A deficient. Vitamin A deficiency is the leading cause of preventable blindness in children.
