Maintaining a Ca:P ratio of 1:1 to 2:1 helps support what health aspect?

Maintaining a Ca:P ratio of 1:1 to 2:1 helps support what health aspect?

• A. Respiratory function
• B. Digestive health
• C. Bone mineralization
• D. Muscle strength

Answer: (C)

Calcium and phosphorus balance directly affects bone mineralization, because bone strength comes from a mineral matrix formed as calcium phosphate (hydroxyapatite) in bone. Keeping a dietary calcium to phosphorus ratio around 1:1 to 2:1 ensures there is enough calcium available for bone deposition while preventing excessive phosphorus that can interfere with calcium absorption and mineralization. When this balance is maintained, bones mineralize properly and skeletal health is supported. While calcium and phosphorus also play roles in muscle function and energy metabolism, the ratio’s most direct impact is on bone mineral content, making bone mineralization the correct health aspect reflected by this ratio.
