Nutrients for Wound Healing

Eating the right nutrients and foods can help promote healing and reduce the risk of infection during wound healing. After surgery, proper nutrition is essential for wound healing and to reduce the risk of complications. Here are some key nutrients for wound healing that can help you with your recovery:


Protein is essential for wound healing after surgery. It is important to consume enough high-quality protein to provide the building blocks necessary for tissue repair. Sources of high-quality protein include lean meats, fish, poultry, eggs, legumes, nuts and seeds, and dairy products. Protein supplementation may also be needed depending on the type and severity of the wound.

Eating a varied diet that includes all these foods will ensure you are getting enough protein to support your wound healing process. In addition, adequate hydration is also important as it helps ensure blood flow to the wound area.

Vitamin C

Vitamin C is essential for wound healing. It helps to form collagen, the structural protein that strengthens connective tissues and is used to form scar tissue at the site of a wound or surgical incision. Vitamin C also helps to increase vascularization and angiogenesis, which is necessary for healthy tissue regrowth in wounds. Additionally, it helps reduce inflammation, which accelerates healing.

Foods rich in Vitamin C include:

  • Oranges and orange juice
  • Red peppers
  • Grapefruits and their juices
  • Kale
  • Broccoli
  • Kiwi fruit
  • Strawberries

If you’re unable to obtain sufficient vitamin C through your diet alone then the intake of a supplement may help to ensure an adequate level of this nutrient for optimal wound healing after surgery.


Zinc is an essential mineral for wound healing and it plays a role in collagen synthesis, tissue regeneration, and immune health. It also helps to reduce inflammation.

Foods that are high in zinc include red meats, poultry, seafood such as oysters, fortified cereals and dairy products. Zinc supplements may be necessary if dietary intake is low or inadequate. Eating a balanced diet with plenty of fresh fruits, vegetables and healthy proteins like fish or eggs can help ensure adequate zinc intake necessary for proper wound healing.

Additionally drinking at least 8 glasses of water per day helps to prevent dehydration which can slow down the healing process.


Iron is an essential mineral that plays a critical role in wound healing and overall health. Iron helps form hemoglobin, which is the protein in red blood cells that carries oxygen to your cells, tissues and organs. A lack of iron can lead to anemia, which can cause fatigue and make it harder for wounds to heal. Therefore, it’s recommended that people with wounds get enough iron in their diet.

Good food sources of iron include:

  • Poultry
  • Red meat
  • Beans
  • Fortified breads and cereals
  • Nuts
  • Tofu

Eating a variety of iron-rich foods can help ensure you meet your daily recommended amount of iron during the healing process. Iron supplements are also available from pharmacies if necessary.

Foods to Avoid

When it comes to wound healing, the type of food you eat can be just as important as the type of treatment you receive. Eating the right foods can help aid healing, while certain foods can delay the healing process or even worsen your wound. In this article, we’ll be discussing which foods to avoid during your post-surgery healing period.

Processed Foods

Processed foods are those that have been altered in some way before being consumed. These foods may contain added fat, sugar, salt and preservatives, and they can often lack essential nutrients. Processed foods are generally considered high-calorie and low-fiber as well as lacking essential minerals, vitamins and other essential nutrients needed for proper healing after surgery. Processed foods can also contain large amounts of unhealthy fats (like trans fats), unhealthy refined grains (white bread and white pasta) and highly processed meats (hot dogs).

Eating a diet high in processed foods is linked to a higher risk of obesity, diabetes, heart disease and certain types of cancer. It’s best to avoid processed foods during recovery periods because they can slow down the healing process or lead to complications like infection due to their low nutrient content. Instead, focus on eating nutrient-dense whole foods like fruits, vegetables, nuts, seeds and lean proteins to ensure adequate nutrition for wound healing after surgery.

Sugary Foods

It is important to limit or avoid sugary foods while healing after surgery. These foods can cause inflammation, increased swelling, and other complications that can prolong the recovery period. Sugary foods such as candy, soda, ice cream, and juice should be avoided if possible. It is also important to avoid processed and refined carbohydrates like white flour and white sugar as much as possible as these may form free radicals (toxins) in the body which can decrease the efficiency of healing.

Additionally, sugary foods often contain a high amount of sugar which can lead to high blood sugar levels resulting in slower wound healing. Eating more nutrient-dense meals will provide more beneficial nutrients needed for healing while avoiding unhealthy ingredients that could potentially damage the recovery process.


Alcohol is a commonly consumed beverage but it may impede wound healing after surgery. Alcohol can interfere with the body’s ability to absorb certain nutrients, vitamins, and minerals which are essential for optimal healing. Additionally, alcohol can cause dehydration which can slow down the healing process. Additionally, excessive alcohol consumption may lead to infection due to its immunosuppressant properties.

It is advised for patients who have had surgery to not consume any alcohol within 24 hours of their procedure and for six weeks afterward as it could further delay the wound healing process. Other foods that should be avoided during this time include:

  • Processed foods that are high in sugar and salt.
  • Fried foods.
  • High-fat dairy products.

Eating for Faster Healing

Eating the right foods can be key in recovering from surgery, as the nutrients found in the food you consume can directly help in the wound healing process. Certain foods provide the body with essential vitamins, minerals, and other nutrients that have been linked with faster wound healing.

Let’s review some of the best foods to support wound healing:

Eat a Balanced Diet

A balanced diet is essential for wound healing following surgery or other medical treatments. While there are some additional specific dietary recommendations depending on the individual and their condition, some basic dietary guidelines can help ensure that your body has the right nutrients to heal.

First and foremost, eating a balanced diet of a variety of foods from each food group will give your body the vitamins and minerals it needs to heal. Choose whole, unprocessed foods whenever possible, such as:

  • Fruits
  • Vegetables
  • Legumes (beans, peas)
  • Nuts and seeds
  • Lean proteins (fish and poultry)
  • Whole grains (quinoa)
  • Dairy products (yogurt)
  • Healthy fats (olive oil)
  • Herbs/spices

Eating a balanced diet will provide you with plenty of proteins necessary for wound healing; vitamins A, B-complex, C and E; minerals such as zinc; omega-3 fatty acids found in fish like salmon; prebiotics found in whole grains; antioxidants found in colorful fruits; calcium from yogurt; and fiber from all sources.

Increase Protein Intake

Increasing your protein intake while healing after surgery is essential in ensuring optimal wound healing. Protein plays a vital role in building and maintaining your body’s tissues, particularly muscle, skin, and connective tissue. Without adequate protein in your diet, wounds will not heal as quickly and can be more prone to infection.

Most healthy adults should aim to consume around 0.8-1.2g/kg of body weight per day or about 20-30% of their overall daily dietary energy from proteins. The best protein sources for wound healing include:

  • Lean meats such as beef, chicken, fish and eggs
  • Plant proteins such as legumes (beans and lentils) nuts and seeds
  • Dairy products such as plain Greek yogurt and cottage cheese

Try to opt for minimally processed choices with less added sugars for the greatest benefit to your health overall.

Eat Foods Rich in Vitamin C

Vitamin C is one of the most important components of proper wound healing. It helps promote the production of collagen, a structural protein that aids in wound fill-in. Additionally, Vitamin C also plays an integral role in the body’s inflammatory response, helping to reduce swelling and redness which can delay healing.

To optimize peak wound healing post-surgery, aim to eat foods rich in Vitamin C such as:

  • Oranges
  • Strawberries
  • Bell peppers
  • Kale
  • Broccoli

Focusing on eating Vitamin C-rich foods is beneficial for any type of surgery or wound, whether it’s external skin trauma or internal organ repairs. In addition to these fresh fruits and vegetables other sources of Vitamin C include:

  • Tomatoes
  • Papaya
  • Kiwi fruit

For those who struggle with food allergies or GI issues that limit the types of food they can enjoy regularly canned fruits and frozen vegetables are also excellent sources of this essential nutrient.

Drink Plenty of Water

Water is essential for wound healing, as it helps the body flush out toxins. Staying hydrated also helps keep our cells healthy, which can aid in faster and improved healing. If you’ve had surgery recently, it’s important to make sure you’re drinking plenty of water to help with the repair process. Aim for at least 8 glasses of water per day to ensure you stay hydrated.

Make sure to avoid sugary drinks as much as possible because sugar can interfere with proper wound healing. When choosing beverages, opt for electrolyte-rich options like coconut water and cranberry juice to support your body in regaining optimal cell function. Herbal teas are also great options; green tea has multiple health benefits and can even boost your metabolism for improved health overall.


In conclusion, proper nutrition is essential for optimal wound healing after surgery. Eating a balanced diet that emphasizes plant-based whole foods, such as fruits and vegetables, helps support the body’s natural healing process. A diet rich in protein, vitamins and minerals is important for tissue repair, collagen production, and overall health. Additionally, including foods with anti-inflammatory properties can help combat inflammation in the body which can impede the healing process after surgery.

In summary, a healthy well rounded diet is one of the most powerful tools to support your recovery after surgery so make sure to nourish your body following your procedure.
