Osteoporosis patients should pay special attention to their diet. Firstly, consume foods rich in calcium and vitamin D, such as milk, cheese, yogurt, dark green vegetables, and fish. Secondly, take adequate protein but avoid excessive animal protein as it may increase calcium loss. It's also important to limit caffeine and alcohol intake as they can affect calcium absorption. Lastly, maintain a balanced diet and avoid extreme dieting or consuming only one type of food, which helps in maintaining bone health.
