01 Minerals are important for what?
Answer and explanation
Correct answer: D. Bones, blood, and body functions
Explanation: Minerals are inorganic nutrients that perform structural and regulatory functions in the body. Calcium and phosphorus help build and maintain bones and teeth; iron is needed for haemoglobin and oxygen transport; sodium and potassium help maintain fluid balance and nerve and muscle activity; and iodine supports thyroid hormone production. Thus minerals contribute to bones, blood, and normal body functions. They do not primarily affect plate shine, food smell, or cooking time.
