Protein is a necessary ingredient for skin and tissue growth. Eating 2 to 3 servings per day will stimulate wound healing. Some good sources of protein are:  Meats and poultry Beans Eggs Dairy products like milk, cheese, and yogurt, especially Greek yogurt Soy protein products Fats are needed for the formation of cells, so you'll need plenty to make your wound heal quickly and efficiently. Make sure the fats you're getting are polyunsaturated and monounsaturated fats, or "good fats." Saturated fats from junk foods won't help you heal and can cause other health problems. Sources of "good fats" that will help you heal are lean meats, vegetable oils such as sunflower or olive, and dairy products. Carbohydrates are important because your body uses them for energy. Without them, your body will break down nutrients like protein to get its energy. This can slow the healing process because protein and fats will be diverted from healing your wound. Prevent this by eating cereal, bread, rice, and pasta daily. Go for complex carbohydrates over simple carbohydrates. Complex carbohydrates are digested more slowly by your body, meaning they are less likely to spike your blood sugar. Foods containing complex carbs, such as whole grain breads, cereals, and pastas, sweet potatoes, and whole oats, also generally contain more fiber and protein. Both these vitamins help wounds heal by stimulating cell growth and fighting inflammation. They also fight infection while the cut is still healing.  Sources of vitamin A include sweet potatoes, spinach, carrots, herring, salmon, eggs, and dairy products. Sources of vitamin C include oranges, yellow peppers, dark green vegetables, and berries. Zinc helps synthesize proteins and develop collagen, helping your wounds heal. Eat red meats, fortified cereals, and shellfish to get enough zinc in your diet. Keep your fluid intake up to help improve circulation, which bring essential nutrients to your wound. Water also helps your body flush out toxins, which will help prevent infection.
