You are asked to design a short nutrition strategy for an older adult with low bone mineral density and borderline low serum 25-hydroxyvitamin D. Which combined dietary and lifestyle plan best targets both the mineral and vitamin components essential for bone health?

• A. Recommend a high-iron diet with iron supplementation, increase water intake to improve mineral solubility, and advise avoidance of sunlight because sun exposure depletes calcium stores even when vitamin D is low.
• B. Advise eliminating all dairy and protein to reduce phosphate load, prescribe high-dose vitamin A to stimulate osteoblasts, and recommend bed rest which reduces fracture risk by preventing stress on demineralized bones.
• C. Increase dietary calcium through milk or fortified alternatives and leafy greens, ensure adequate dietary phosphate via protein sources, recommend safe sun exposure or vitamin D–fortified foods/supplementation, and include weight-bearing exercise to stimulate bone remodeling.
• D. Suggest a low-sodium, low-mineral diet combined with long-term corticosteroids to suppress inflammatory bone turnover and increase vitamin K supplements exclusively, since vitamin K alone will restore bone density quickly without affecting vitamin D status.

Answer: (C)
