To promote wound healing after trauma or surgery, patients can eat more fresh fruits, such as apples, bananas, kiwis, dragon fruit, oranges, grapefruit and grapes, which are available because they are rich in vitamins and contain a variety of trace elements such as calcium, iron and zinc. Eating fruits in moderation can replenish the nutrients needed by the body, enhance the immunity of the body and promote wound healing. Patients should also eat more food rich in high quality protein and more green vegetables to replenish the amino acids and vitamins that the body needs to promote wound healing. Patients with wounds should also disinfect and change the wound in time to prevent wound infection. It is important to take rest to strengthen the resistance and promote wound healing.
