Why does milk make bones strong?
Show answer & explanation
Answer: Calcium provides structure
Calcium provides structure ✓ — Correct! Milk is rich in calcium, which is important for bone mineral density. Bones are made of a calcium phosphate mineral called hydroxyapatite. Your body constantly deposits and removes calcium from bones. Adequate dietary calcium ensures strong bone formation, especially during growth. Milk also contains vitamin D, which helps intestines absorb calcium efficiently!
Fat lubricates joints — Wrong. Milk's fat doesn't lubricate joints or strengthen bones. Joint lubrication comes from synovial fluid produced by your body. Bone strength specifically comes from calcium and other minerals, not fat.
Vitamins repair damage — Wrong. While milk does contain some vitamins, and vitamin D helps calcium absorption, the basic reason it strengthens bones is the calcium content. Calcium is the primary structural mineral in bone tissue.
