Which mineral is crucial for bone health and is commonly found in dairy products?

• A. Iron
• B. Calcium
• C. Sodium
• D. Magnesium

Answer: (B)

Calcium is the mineral most closely linked to healthy bones because it forms the mineral structure that gives bones their strength, and the skeleton stores most of the body's calcium for use when needed. Dairy products such as milk, yogurt, and cheese are especially rich sources of calcium, making it easier to meet daily needs and support bone density as you grow. Calcium absorption is helped by vitamin D, so having vitamin D in the diet or from sunlight supports how well you use the calcium you take in.

Other minerals play roles in the body, but they don’t target bone health as directly or are not as commonly supplied by dairy. Iron is essential for oxygen transport in blood, sodium helps with fluid balance, and magnesium also contributes to bone metabolism, but calcium is the standout mineral associated with building and maintaining strong bones and is most strongly connected to dairy sources.
