Osteoporosis prevention recommendations include which combination?

• A. Weight-bearing activities, vitamin D, avoid caffeine, smoking and alcohol, and estrogen supplementation
• B. High-sodium diet
• C. Avoiding all dairy products
• D. Sedentary lifestyle

Answer: (A)

Osteoporosis prevention hinges on providing the bones with mechanical stimulation, building blocks, and factors that protect against bone loss. Weight-bearing activities place stress on the bones, signaling osteoblasts to maintain or increase bone density, which helps prevent osteoporosis. Adequate vitamin D is essential for calcium absorption and bone mineralization, so keeping vitamin D levels sufficient supports the calcium that bones rely on for strength. Avoiding smoking and limiting alcohol intake reduce factors that accelerate bone loss and fracture risk, preserving bone health. Limiting caffeine intake is also commonly advised because higher caffeine consumption can increase calcium excretion, potentially weakening bones over time. Estrogen supplementation, when clinically appropriate for postmenopausal individuals and used under medical supervision, helps reduce bone resorption and maintain density. Together, these elements address physical stimulus, nutrient availability, and hormonal influences on bone health.
