Calcium is a vital mineral for bone health, as it provides the necessary structure and strength to bones. It plays a crucial role in the bone remodeling process, where old bone tissue is replaced with new. Adequate calcium intake helps prevent bone loss as people age and is essential in reducing the risk of osteoporosis. The body cannot produce calcium, so it must be obtained through diet or supplements. Foods rich in calcium include dairy products, leafy greens, and fortified foods. Ensuring sufficient calcium intake throughout life is vital for maintaining strong and healthy bones.
