Blood loss during surgery will make the surgical patient's body protein and nutrients lost, and preoperative and postoperative dietary restrictions for a period of time also make nutritional intake is insufficient, thus consuming the body's nutritional reserves, if not timely supplementation of adequate nutrition, will make the wound healing time delayed, and if an infection occurs the wound will heal poorly. Wound healing requires reasonably adequate nutrition, especially high-quality protein, zinc, iron and other trace elements and B vitamins, vitamin C, etc., is a necessary nutrient for wound healing. Foods containing high-quality protein are poultry, livestock, fish, eggs, milk and other animal foods, and animal foods are rich in trace elements and B vitamins, which are conducive to wound healing.

The flesh of raw fish is tender and contains less water than ordinary freshwater fish, so it is rich in high-quality protein and zinc and other trace elements, which is a good food for postoperative wound healing, and the nutritional industry has not found that it contains substances that make scars bigger.

Fruits are rich in vitamins and minerals, especially apples, oranges, strawberries, dates and other vitamin C. Vitamin C promotes the formation of collagen, which can promote wound healing. Bananas, like ordinary fruits, have no special unfavorable factors for the body, and are rich in vitamin C, potassium and pectin, which help the balance of water and electrolytes and the recovery of postoperative intestinal function. But good food also needs to be in moderation, excessive food will increase the burden on the gastrointestinal tract, not conducive to absorption.

So, after the surgery, we need to supplement sufficient and balanced nutrition in time, pay attention to the supplementation of high-quality proteins, vitamins and trace elements, such as increasing the intake of animal foods, eggs and milk and fruits, and discard those unscientific folk rules taboo, in order to promote the wound healing and physical recovery. Recommended several foods conducive to postoperative recovery: lean meat, chicken, pigeon, eggs, milk, oysters, raw fish.
