What dietary component is crucial for maintaining bone health?

• A. Protein
• B. Carbohydrates
• C. Calcium
• D. Fats

Answer: (C)

Calcium is a vital dietary component for maintaining bone health because it is the primary mineral found in bones. It plays a critical role in the development of bone mass during childhood and adolescence, when the body is most actively building bone density. Throughout adulthood, sufficient calcium intake helps to maintain bone density and prevent osteoporosis, a condition characterized by weak and brittle bones.

The body requires a continuous supply of calcium to support various physiological functions, including muscle contraction and blood coagulation. When dietary calcium is insufficient, the body will extract calcium from the bones, which can lead to decreased bone density over time. Therefore, ensuring adequate calcium intake through diet or supplements is essential for preserving skeletal strength and reducing the risk of fractures, especially in postmenopausal women and the elderly.

While protein, carbohydrates, and fats are important components of a balanced diet and provide energy and nutrients for various bodily functions, calcium's specific role in bone mineralization makes it uniquely crucial for maintaining bone health. This underscores the significance of including calcium-rich foods, such as dairy products, leafy greens, and fortified foods, in the diet to support overall skeletal integrity.
