Osteoporosis is a condition where bones become weak and fragile, particularly common in people over 50. To prevent and manage osteoporosis, consider the following: 1. Eat foods rich in calcium and vitamin D, like milk, dairy products, and leafy greens; 2. Engage in regular weight-bearing and aerobic exercises, such as walking, running, and weightlifting; 3. Avoid smoking and excessive alcohol consumption, as these are harmful to bone health; 4. Have regular bone density tests to catch any issues early; 5. If advised by a doctor, take calcium supplements or vitamin D as needed.
