Final answer:
Typically inadequate minerals in children's diets include calcium, iron, and zinc, with sodium deficiency being less common. Balanced intake of calcium and iron is necessary for optimal health.
Step-by-step explanation:
Minerals that are frequently inadequate in children's diets include calcium, iron, and zinc. Sodium is typically not deficient in children's diets. Calcium deficiency may lead to poor bone development, such as in rickets, which is associated with calcium malabsorption and a deficiency in vitamin D. Iron is crucial for the formation of hemoglobin in red blood cells and its inadequacy can lead to anemia. Zinc plays a role in various metabolic processes and immune function. Both calcium and iron must be balanced in the diet, as too much calcium can interfere with iron absorption.
