Calcium is pivotal in the prevention of osteoporosis, a condition characterized by weak bones and an increased risk of fractures. Adequate calcium intake supports the development and maintenance of strong bones throughout life. It is essential for bone density, especially during childhood and adolescence when bones rapidly grow. A consistent dietary intake of calcium-rich foods such as dairy, leafy greens, and fortified products can significantly reduce the risk of osteoporosis as individuals age. Therefore, ensuring sufficient calcium consumption is critical for maintaining long-term bone health.
