The quality of your diet can affect how your body heals after a wound. Protein is an important factor in each step of wound healing. The body heals wounds in three stages: inflammation, tissue formation and remodeling. Protein works as both a stimulate and a factor to reproduce a healthy skin and blood vessel system.
Protein and Inflammation
The first step your body takes when healing a wound is the inflammation phase. During this stage, blood flow to the wound is increased in order to deliver white blood cells and protein to the area. The first part of this stage involves cleanup of the site. Neutrophils, a type of white blood cell, work first to remove foreign debris and bacteria from the wound. Next, monocytes, another type of white blood cell, binds to monocyte chemoattractant protein 1, which stimulates the monocyte to release granulated fibers that will become the substance that stops bleeding. In the end, it is fibrin, a protein fiber, that stops the bleeding. All of the steps involved in the blood clot formation end in the making of a protein.
Protein and Epithelialization
The second phase to healing a wound involves the regrowth of skin, or epithelial cells on the affected area. This process can occur just after a few hours after the injury. The interaction between epithelial cells and extra-cellular matrix proteins allows the cells to break down the blood clot and form skin again.
Protein and Remodeling
Once the wound is under control, your body next works to rebuild the epidermis and reconstruct damaged blood vessels. Protein works in both of these stages. The protein fibrin now acts as a means to support newly built epithelial cells. After the epithelial tissue is rebuilt, the body works on the restructuring the damaged blood vessels. Proteins contribute by stimulating the growth of new vessels and helping to build blood vessel walls.
Recommendations
According to the Cleveland Clinic, people who are trying to heal a wound may consider increasing intake of protein. This is true, especially for those who have undergone surgery and have a substantial wound. Try eating 0.8 to 1.0 g or protein per kilogram of your body weight. Choose healthy sources of protein like fish, eggs, meat and soy.
