The British foot Doc’s guide to Nutrition for wound care and Post-surgical Healing. 

The process of wound healing is associated with a multitude of factors. These include among others, adequate blood flow, creation of a healthy wound bed and adequate off-loading (with pressure wounds), and while these factors are routinely considered by your wound care team, the necessity of nutrition is sometimes overlooked. Nutrition refers to the act of eating and drinking a healthy and balanced diet that provides nutrients to aid in body function and health. In reference to wound care, nutrients are essential in the fight against infection and assists your body to build and repair tissue.  Nutrients considered essential for proper body function are: Protein, Carbohydrates, Fats, Vitamins, Minerals and water, each one will provide different ways to assist in wound healing. 

Protein

The necessity for adequate protein intake can not be understated, they provide the main building blocks for tissue growth, cell renewal, and repair throughout the wound healing process. They play a significant role in the entire process of wound healing via RNA and DNA synthesis, collagen and elastic tissue formation, immune system function, epidermal growth, and keratinization. 

In regards wound healing it is recommended around 1.5g of protein per kilogram weight per day, so for example a 175lb (~80kg) person with a foot wound needs to consume 120g of protein per day for optimum wound healing.  

Protein rich foods include:

Lean meats: chicken, turkey, beef, and pork [e.g 1 chicken breast = 54g of protein]

Fish: salmon, tuna, and mackerel [e.g 1 filet of salmon = 80g of protein]

Dairy products: milk, cheese and yogurt. [e.g 1 cup of greek yogurt = 20g of protein]

Beans, Peas and Lentils: kidney beans, pinto beans, white beans, black beans, lima beans, fava beans, soybeans, chickpeas, black-eyed peas, pigeon peas, split peas, lentils, and edamame. [e.g 1 cup of chickpeas = 39g of protein]

Nuts and Seeds: almonds, hazelnuts, walnuts, peanuts, chia seeds, pumpkin seeds, sunflower seeds, and peanut butter. [e.g 1 cup of almonds = 20g of protein]

Protein Supplements

While it always best to obtain protein from food sources there are some protein supplements that may aid in reaching your protein intake quota;

ProHeal Liquid Protein Supplement: A protein-concentrated supplement offering 15g of protein and 100 calories in each serving (2 tablespoons).

Carbohydrates

Carbohydrates play a crucial role in wound healing by providing the primary source of energy required for tissue repair and regeneration. During the healing process, the body’s metabolic demands increase significantly to support cellular activity such as collagen synthesis, immune response, and tissue remodeling. Carbohydrates help fuel these processes by supplying glucose, the preferred energy source for cells.

When a wound occurs, the body enters a hypermetabolic state where energy requirements surge to facilitate repair. Without an adequate intake of carbohydrates, the body may start breaking down protein (from muscle tissue) to meet these energy demands, which can slow healing and lead to muscle wasting. Carbohydrates not only spare protein for essential structural functions but also support immune cells, fibroblasts, and epithelial cells in their roles during the different phases of healing.

It is important to choose nutrient-dense, whole food sources rather than refined carbohydrates, which can cause blood sugar spikes and inflammation, potentially hindering the healing process. 

Here are some examples of healthy carbohydrate options that support wound healing:

1. Whole Grains: Foods like oats, brown rice, quinoa, and whole wheat provide complex carbohydrates that are digested slowly, ensuring a steady release of energy. They are also rich in fiber, vitamins, and minerals that support overall health and wound repair.
2. Starchy Vegetables: Sweet potatoes, butternut squash, and carrots are rich in both complex carbohydrates and beta-carotene, which is a precursor to vitamin A—a nutrient important for skin integrity and wound healing.
3. Legumes: Beans, lentils, and chickpeas are excellent sources of carbohydrates, fiber, and protein, making them ideal for wound healing. They also contain micronutrients like zinc, which is important for tissue repair.
4. Fruits: Fresh fruits like apples, berries, and bananas provide simple carbohydrates in a nutrient-rich package, including antioxidants that can help reduce inflammation and promote healing.

Carbohydrates to avoid

Refined carbohydrates are processed foods that have been stripped of their natural fiber, vitamins, and minerals, resulting in a product that is rapidly absorbed by the body, often causing spikes in blood sugar levels. Consuming these types of carbohydrates can hinder the wound healing process for several reasons, including promoting inflammation, reducing immune function, and contributing to poor blood sugar control, all of which impair the body’s ability to repair tissue.

Examples of Refined Carbohydrates to Avoid During Wound Healing:

1. White Bread: Made from refined flour, white bread lacks fiber and key nutrients. It is quickly digested and can cause spikes in blood sugar levels.
2. Sugary Snacks: Foods like pastries, cookies, and cakes contain high levels of refined sugar and refined flour, which contribute to inflammation and poor glycemic control.
3. Sugary Cereals: Many breakfast cereals are made with refined grains and added sugars, offering little nutritional value and spiking blood sugar after consumption.
4. White Rice: White rice is a refined grain that lacks fiber and essential nutrients found in whole grains like brown rice or quinoa.
5. Soda and Sugary Beverages: Soft drinks and sweetened beverages are high in refined sugars, which provide empty calories and contribute to inflammation and insulin resistance, further impairing healing.
6. Chips and Processed Snacks: These are often made from refined grains and loaded with unhealthy fats, additives, and sodium, which can promote inflammation and hinder the body’s healing processes.

Fats

Fats are an essential component of the diet, especially during the wound healing process. They serve several critical functions that support tissue repair, immune response, and the reduction of inflammation. Fats provide long-lasting energy, aid in the absorption of fat-soluble vitamins (such as vitamins A, D, E, and K), and are vital in maintaining the structural integrity of cell membranes. Healthy fats, in particular, help regulate inflammation, support the immune system, and contribute to faster and more effective wound healing.

Healthy Fat Options for Wound Healing

Choosing healthy fats is important to ensure they support the healing process without contributing to inflammation or other negative health effects. Here are some examples of healthy fat sources that can aid in wound healing:

1. Avocados: Rich in monounsaturated fats, avocados provide energy and promote the absorption of fat-soluble vitamins. They also contain vitamin E, which helps protect cells from oxidative damage during healing.
2. Olive Oil: (e.g  Whole Foods Market, Organic Extra Virgin Mediterranean Olive Oil, Extra virgin olive oil is high in monounsaturated fats and antioxidants. It has anti-inflammatory properties that can aid in controlling the inflammatory phase of wound healing.
3. Fatty Fish: Fish like salmon, mackerel, and sardines are excellent sources of omega-3 fatty acids, which help reduce inflammation and support immune function. Omega-3s also promote healthy skin and tissue regeneration.
4. Nuts and Seeds: Almonds, walnuts, flaxseeds, and chia seeds are high in both omega-3 fatty acids and vitamin E. These nutrients help regulate inflammation, support immune health, and protect against cell damage.
5. Coconut Oil:(e.g Nutiva, Organic Coconut Oil Coconut oil contains medium-chain triglycerides (MCTs), which provide an easily accessible source of energy. It also has antimicrobial properties that can be beneficial in wound care.
6. Eggs: Eggs contain healthy fats, including omega-3s, and are a great source of protein. The yolk also contains essential fat-soluble vitamins like A and D, which are important for skin repair.
7. Nutrient-Dense Oils (e.g., Flaxseed Oil Barlean’s Organic Flaxseed Oil , Hemp Oil (Manitoba Harvest Organic Hemp Oil,: These oils are rich in omega-3 fatty acids, which help manage inflammation and promote wound healing by supporting cellular integrity.

Vitamins

Vitamins play a pivotal role in wound healing by supporting various physiological processes essential for tissue repair, collagen production, immune function, and reducing oxidative stress. Deficiencies in key vitamins can lead to delayed healing, increased risk of infection, and poor tissue regeneration. Ensuring an adequate intake of vitamins during the healing process helps optimize the body’s ability to recover and restore damaged tissue.

Mineral Supplements for Wound Healing

While whole foods are the best source of minerals, there are times when mineral supplements may be needed to support wound healing. This is especially true if dietary intake is insufficient, if a person has specific medical conditions that affect mineral absorption, or if there is an increased need for minerals during the healing process. Supplements can help fill these gaps, and a multi-mineral supplement (e.g Dr. Berg Trace Minerals Enhanced Complex may be a convenient option but it is important to use them under the guidance of a healthcare provider to avoid toxicity or interactions with medications.

Water

Lastly the need for adequate water intake for wound healing can not be understated. Proper hydration ensures that the body can effectively deliver nutrients, maintain tissue integrity, and remove waste products from the wound site. Dehydration, on the other hand, can significantly impair healing by slowing down cellular processes and increasing the risk of infection.

How Much Water Is Recommended?

The amount of water you should drink daily varies based on individual factors such as age, body weight, activity level, and environmental conditions. However, general guidelines recommend:

• For men: Approximately 3.7 liters (125 ounces) per day, including all beverages and food sources of water.
• For women: Approximately 2.7 liters (91 ounces) per day, including all beverages and food sources of water.

It’s important to note that these recommendations can increase if you are recovering from surgery, illness, or have a wound that requires healing. Factors such as fever, infections, hot weather or taking pain medications can also raise your hydration needs.

When choosing your water source, it is recommended to select mineral or spring type water (e.g Evian Natural Spring Water rather than distilled water. Mineral or spring water is generally considered better due to its mineral content and potential health benefits (as previously stated), while distilled water is stripped of these beneficial elements.

Some final Notes: 

Always consult your physician or registered dietitian (and your podiatrist) before starting any new supplement — particularly if you have diabetes, kidney issues, or are taking medications.
