Wound Healing and your Diet

Medically reviewed by Last updated on Jan 5, 2023.

Your body uses nutrients from healthy foods to heal wounds caused by injury, surgery, or pressure injuries. There is no special diet that will heal your wound, but a healthy meal plan can help your wound heal faster. Nutrients that are important for healing are protein, zinc, and vitamin C. Liquids are also important for wound healing.


Follow a healthy meal plan:

  • Eat a variety of foods from each food group every day. Eat regular meals and snacks to help you get enough calories and nutrients. If you have trouble eating 3 meals each day, eat 5 to 6 small meals throughout the day instead. Include good sources of protein, zinc, and vitamin C each day.
    Healthy Foods
  • Drink liquids as directed. Drink plenty of liquids during and between meals, unless your healthcare provider has told you to limit liquids. Ask your healthcare provider or dietitian how much liquid to drink each day and which liquids are best for you.
  • Limit unhealthy foods, such as those that are high in fat, sugar, and salt. Examples include doughnuts, cookies, fried foods, candy, and regular soda. These kinds of foods are low in nutrients that are important for healing.

Good sources of protein:

Your dietitian will tell you how much protein and how many calories you need each day. The average amount of protein in foods is listed below in grams (g). To find the exact amount of protein in a food, read the food labels on packaged items.

Good sources of vitamin C:

Vitamin C is found in fruits and vegetables. Fruits such as oranges, strawberries, grapefruit, cantaloupe, and tangerines are good sources of vitamin C. Red and green bell peppers, broccoli, potatoes, tomatoes, and cabbage are also high in vitamin C.

Sources of Vitamin C

Good sources of zinc are beef, liver, and crab. Smaller amounts of zinc are found in sunflower seeds, almonds, peanut butter, eggs, and milk. Other foods that contain zinc include wheat germ, black-eyed peas, and whole-grain products.

How to add extra calories to foods:

Your dietitian may recommend that you add extra calories to your meals if you are not eating enough. You can increase calories by adding butter, margarine, sugar, or jam to foods. Work with your dietitian if you have other medical conditions and need to follow a special diet.

What else you should know about nutrients and wound healing:

Your healthcare provider or dietitian may recommend vitamin and nutrition supplements if your body is low in certain nutrients. If your dietitian recommends a liquid nutrition supplement, take it between meals. Ask your healthcare provider which supplements are right for you.
