Which nutrient strengthens bones?

• A. Minerals
• B. Water
• C. Carbohydrates
• D. Fats

Answer: (A)

Bone strength comes from minerals that form the bone’s mineral matrix. The main minerals in bone are calcium and phosphorus, which crystallize as hydroxyapatite to give bone its hardness and rigidity. Magnesium and other trace minerals also support bone quality and remodeling. If a diet is deficient in these minerals, bones can become weak and fractures more likely, even if energy intake is adequate. Water is essential for hydration and helps transport minerals, but it doesn’t provide the hard mineral material that strengthens bone. Carbohydrates and fats supply energy for growth and daily function, but they aren’t the materials that directly harden bone. In growing animals, ensuring adequate calcium and phosphorus is especially important to prevent skeletal issues.
