What lifestyle factor can significantly affect bone health?

• A. Regular exercise
• B. Sitting for long periods
• C. Consumption of sugary foods
• D. A sedentary lifestyle

Answer: (D)

A sedentary lifestyle is significantly correlated with poor bone health. Engaging in regular physical activity helps maintain bone density by stimulating bone formation through the mechanical stress exerted on bones during weight-bearing and resistance exercises. When the body is inactive for prolonged periods, it lacks the necessary stimulation to strengthen the bones, which can lead to decreased bone density and an increased risk of osteoporosis and fractures. Therefore, maintaining an active lifestyle that includes mobility and exercise is crucial for promoting optimal bone health and reducing the risk factors associated with bone deterioration.

Other lifestyle factors such as regular exercise can improve bone health, while sitting for long periods or the consumption of sugary foods can indirectly contribute to poor bone health, but the impact of a sedentary lifestyle is particularly detrimental as it removes the necessary stimulus for bone maintenance and growth.
