The smooth healing of surgical incisions relies on comprehensive and balanced nutritional support, in which high-quality protein, trace element zinc, and vitamins C, E, and B play a crucial role. These nutrients are not only the foundation for the formation of new tissue, but also directly participate in and accelerate the complex process of wound healing.

Firstly, foods rich in high-quality protein, such as meat (poultry, livestock, and fish), eggs, and dairy products, are not only important sources of high-quality protein, but also rich in various trace elements and B vitamins. These components work together to provide a solid nutritional foundation for rapid wound recovery.

In the early stage of incision healing, fibroblasts in the wound granulation tissue become active, secreting large amounts of collagen to form a sturdy collagen fiber network, thereby allowing the incision edges to adhere closely. Collagen, as a high molecular weight substance in the body, is a key component of connective tissue. Its abundant sources mainly include animal based foods such as poultry, livestock, and fish.

In addition, the synergistic effect of zinc and vitamin C should not be underestimated. Zinc not only promotes the absorption and utilization of vitamin C, but also directly participates in the synthesis of collagen, effectively enhancing the body's immunity and accelerating incision healing. Foods rich in zinc, such as corn, soybeans, radishes, mushrooms, etc., should be included in the postoperative diet plan in moderation.

Vitamin C, as a water-soluble vitamin, is important for promoting incision healing, inhibiting melanin production, and maintaining normal physiological functions of blood vessels, muscles, bones, and teeth. Due to the inability of the human body to synthesize vitamin C on its own, fresh fruits and vegetables such as jujubes, kiwis, citrus fruits, hawthorns, strawberries, tomatoes, bean sprouts, green leafy vegetables, etc. have become an indispensable source of food.

Vitamin E, as a fat soluble vitamin, has antioxidant properties that help reduce oxidative stress at the incision site, promote healing, reduce scar formation, and improve local blood circulation. Foods rich in vitamin E include fruits and vegetables (such as kiwi, asparagus, spinach, yam, etc.), nuts (almonds, hazelnuts, walnuts, etc.), pressed vegetable oils (corn oil, soybean oil, peanut oil), and cod liver oil.

The B vitamins have a significant effect on maintaining skin health and promoting incision healing. They are widely distributed in animal liver, red meat, eggs, fish, dairy products, and various vegetables. Balanced intake can help accelerate postoperative recovery.

To sum up, in order to promote the high-quality healing of the surgical incision, it is recommended that patients, under the guidance of the doctor, gradually start to take liquid food (such as porridge, soup, milk, etc.) from 6 hours after the operation, and then gradually transition to a balanced diet containing rich high-quality protein, fresh fruits and vegetables, moderate amounts of nuts and whole grains. For patients with eating difficulties, parenteral nutrition may be considered for necessary nutritional supplementation.
