Why does reduced dietary mineral intake increase fracture risk in elderly individuals?

💡 Explanation

Reduced mineral intake compromises bone mineralization, affecting the bone remodeling process because adequate mineral deposition is required for proper bone matrix formation. Therefore, bone strength decreases, increasing fracture risk, rather than increased osteoblast activity compensating or hormonal changes causing this effect.
