On the basis of balanced diet, moderate consumption of food rich in calcium, vitamin C and protein can promote fracture healing and avoid delayed fracture healing caused by malnutrition. 1. Moderate consumption of foods rich in high quality protein, such as fish, beef, etc., can supplement the body with high quality protein and provide raw materials for the body’s repair. 2. Moderate consumption of calcium-rich foods such as milk, tofu, river shrimp, etc., as calcium is the main component of bone, so moderate supplementation of calcium is conducive to fracture healing. 3. Vitamin C also helps to maintain bone health, so moderate consumption of some oranges, kiwis and other foods rich in vitamin C is also conducive to bone health. Fracture patients are advised to have a scientific and reasonable diet under the guidance of a doctor or dietitian to avoid delayed fracture healing caused by malnutrition.
