Step-by-step explanation:
One way of preventing osteoporosis in middle-aged women is by avoiding smoking. Smoking is identified as a risk factor for osteoporosis, which can be controlled through behavioral changes. Additionally, it is important to engage in weight-bearing exercise, consume a diet rich in calcium and vitamin D, and avoid excessive alcohol consumption and the intake of carbonated beverages to help maintain bone density and reduce the risk of osteoporosis.
