The mineral critical for bone health is calcium. It plays a fundamental role in developing and maintaining strong bones and teeth. Adequate calcium intake is essential throughout life, especially during childhood, adolescence, and older age, when the risk of osteoporosis and fractures increases. Foods rich in calcium include dairy products, leafy greens, and fortified foods. Vitamin D also plays a vital role in calcium absorption and bone health. Ensuring a proper balance of these nutrients is crucial for maintaining skeletal integrity and overall physical fitness.
