High-protein diets can have both benefits and drawbacks for osteoporosis. On the positive side, adequate protein is essential for maintaining bone health and muscle mass, which can help support and protect bones. Protein can also help with the repair of tissues. However, some studies suggest that extremely high protein intake may lead to calcium loss through urine, which could potentially weaken bones over time. It's important to find a balanced diet that includes enough protein to support bone health without causing adverse effects. Consulting with a healthcare professional can help you determine the right amount of protein for your needs.
