Wound Healing and Nutrition: What to Eat for Faster Wound Healing

From minor scrapes or surgical incisions, our bodies rely on a series of coordinated steps to repair tissue, prevent infection, and support healing. However, many factors contribute to how quickly and effectively your body is able to recover.

At Royal Wound Care, we recognize that the wound healing process doesn’t stop after a patient leaves our office. Nutrition plays a crucial role in the recovery process, making what you eat during this time important. The right foods provide the necessary vitamins, minerals, and protein necessary for optimal rehabilitation.

Nonetheless, nutrition is an often overlooked aspect of wound healing. Therefore, this guide explores the relationship between nutrition and wound healing. More specifically, we will explore which foods promote healing and which foods patients should avoid.

Wound Healing and Nutrition: What to Eat for Faster Wound Healing

When receiving treatment from a wound care specialist, many patients expect dressings, antibiotics, and, in some cases, surgical intervention. However, nutrition plays a critical role in wound healing as well. Recovery should address the entire person—not just what’s happening on the outside.

Ultimately, the body works hard to heal wounds—it’s generally a complex, energy-consuming process. Additionally, each stage of the wound healing journey relies on different nutrients for recovery. With the right nutritional support, patients can experience advanced healing, infection prevention, and reduced complications.

How Does Nutrition Affect Wound Healing?

Supports Tissue Repair and Regeneration

A healthy diet serves as the building blocks for cellular regeneration and tissue repair. When consuming the right nutrients, you’re giving your body the protein, vitamins, and minerals it needs to repair damaged cells while also creating new ones.

More specifically, amino acids are essential for wound recovery. These compounds help drive the healing process by supplying oxygen, supporting both blood flow and nutrient delivery to the wound bed.

Reduces Inflammation and Prevents Complications

Specific nutrients, such as omega-3 fatty acids, play a direct role in reducing inflammation. To elaborate, they regulate the immune response and reduce the overall production of inflammatory molecules.

Not only is this balance necessary for optimal recovery, but excessive inflammation can delay wound healing and lead to complications. For example, a minor abrasion, without the proper care, can develop into a chronic wound, requiring additional attention and more advanced medical interventions.

Strengthens the Immune System

Ultimately, a strong immune system is the foundation upon which wounds heal effectively, quickly, and with fewer complications. To put it lightly, it serves as the body’s first line of defense against external factors—ones that result in prolonged healing.

Vitamins A, C, E, zinc, and protein all contribute to a stronger, more resilient immune system. Moreover, they increase antibodies, protect against cell damage, and fight oxidative stress. Improper nutrition can quickly compromise a patient’s healing journey.

Promotes Collagen Formation

Anytime you have a wound, whether it’s a simple scratch or a more complex venous ulcer, collagen formation is a key process in recovery. It acts as the scaffold of the wound, quietly providing strength and structure to help the body heal.

The proper nutrients help this process even more, as they support tissue regeneration, stabilization of collagen’s new structure, and repair. This is where patients will find that their open, aggravated wound slowly begins to heal and close.

Helps Maintain Hydration and Circulation

Proper hydration is another critical component of efficient healing. And, most patients will be surprised to learn that they don’t just need a glass of water to meet their goal. Nutrition plays a key role in this, too!

Hydration promotes blood circulation while simultaneously delivering oxygen and removing waste products. The less hydrated you are, the thicker the blood becomes. This can result in poor circulation, preventing necessary nutrients from reaching the injury.

What Foods Promote Wound Healing?

While it’s important to know which foods promote healing, it’s also beneficial to understand why. Here are the roles specific nutrients play in a patient’s road to recovery:

Lean Proteins (Chicken, Turkey, Fish, Eggs)

When planning your diet, sources of protein are essential for tissue repair, immune function, and collagen formation. In fact, protein deficiency in wound healing can compromise collagen synthesis, leading to improper healing and a weaker tissue structure.

To avoid this, ensure you’re consuming a sufficient amount of protein tailored to your unique health condition and circumstances. Some examples of protein include: Chicken, turkey, fish, eggs, and ground beef.

Citrus Fruits (Oranges, Grapefruit, Lemons)

While all vitamins and minerals play a role in wound healing, vitamin C is particularly crucial for the formation of collagen, blood vessel growth (angiogenesis), and connective tissue. Essentially, it provides the framework that wounds require when creating new tissue.

Additionally, vitamin C can simultaneously help strengthen the immune system and fight infections. To up your intake, incorporate citrus fruits into your diet. More specifically, oranges, grapefruit, lemons, limes, and pomelos are all rich in antioxidants.

Leafy Greens (Spinach, Kale, Swiss Chard)

In addition to vitamin C, vitamins K and A also support recovery—both of which are found in leafy greens. To break it down further, vitamin K assists in blood clotting, a necessary first step in the healing process. In comparison, vitamin A stimulates epidermal turnover and helps the body fight off infections.

Moreover, leafy greens are rich in magnesium, iron, calcium, and antioxidants. Together, they enhance the body’s ability to supply anti-inflammatory cells to wound sites and provide the necessary energy for healing. Spinach, kale, collard greens, Swiss chard, bok choy, and arugula are all excellent sources that patients can incorporate into their daily diet.

Nuts and Seeds (Almonds, Walnuts, Chia Seeds)

Both nuts and seeds are incredibly rich in healthy fats, vitamins, copper, and minerals—such as zinc and omega-3s. As patients incorporate these nutrients into their diet, they’re actively aiding in reducing inflammation and boosting immune system function.

Additionally, for patients participating in a plant-based diet, nuts and seeds are an excellent source of protein. Apart from the benefits mentioned, zinc is crucial for cell proliferation. On the other hand, copper plays a crucial role in protein synthesis, facilitating tissue regeneration.

Almonds, walnuts, chia seeds, cashews, and flaxseeds are all easy to incorporate and produce incredible results for wound recovery.

Whole Grains (Oats, Brown Rice, Quinoa)

As we mentioned earlier, wound healing is an energy-demanding journey. Patients can help their bodies through the process by incorporating whole grains into their daily diet. Whole grains, which are a type of complex carbohydrate, provide the sustained energy necessary for healing.

Moreover, these nutrients are rich in phenolic compounds, which act as antioxidants to remove harmful waste from injury sites. Their anti-inflammatory effects also help reduce oxidative stress around the wound, ensuring a quick and optimal recovery.

If you’re looking for whole grains to add to your diet, consider oats, brown rice, quinoa, corn, rye, amaranth, and barley.

Greek Yogurt and Fermented Food

Rich in protein and probiotics, Greek yogurt and other fermented foods directly support tissue repair. Although many patients might not be aware, gut health and wound recovery are closely related.

Therefore, supporting the gut through beneficial bacteria strengthens the body's immune response and helps prevent inflammation. A healthier gut allows the body to properly absorb essential nutrients more efficiently, thereby aiding in wound care.

Yogurt, keifer, sauerkraut, kimchi, and miso all contain probiotics necessary for optimal gut health.

What Food to Avoid for Wound Healing?

While tempting, Royal Wound Care strongly encourages patients to avoid certain foods while in the process of healing. Below, we will discuss why this is crucial:

Sugary Foods and Desserts

Sugary foods directly impede recovery by increasing inflammation and slowing the function of immune cells. Additionally, this food group can raise blood sugar levels, therefore restricting optimal blood flow. As a result, oxygen and nutrients cannot reach the wound site effectively, potentially delaying collagen production and tissue repair.

Processed and Fried Foods

Similar to sugary foods, processed and fried foods can further increase inflammation due to higher levels of trans fats. Aside from the lack of nutritional value, these foods can cause sugar spikes, strain the digestive system, and reduce the body’s nutrient stores.

Remember, your body needs additional nutrients during recovery. Without this, patients may experience delayed healing and added complications.

Excessive Alcohol

As we mentioned earlier, sufficient hydration is a crucial aspect of proper recovery. Excessive consumption of alcohol can further dehydrate the body and delay wound healing. Moreover, it can also reduce blood and oxygen flow, delay inflammatory responses, weaken the immune system, and hinder tissue repair.

High-Sodium Foods

Foods high in salt are naturally rich in sodium. When managing recovery and wound healing, high-sodium diets can contribute to fluid retention and overall inflammation. As a result, this restricts blood flow, impairs the function of immune cells, and disrupts tissue regeneration. The more sodium a patient consumes, the more complex their healing journey can become.

Refined Carbohydrates (White Breads, Pastries, Pasta)

While complex carbohydrates are encouraged during recovery, refined carbohydrates are not. These foods result in rapid blood sugar spikes, similar to those experienced during meals with high sugar. And, as we’ve repeated previously, they can also weaken immune function and increase inflammation.

A well-balanced diet can help patients recover more quickly and effectively.

Proper nutrition is one of the most powerful tools for supporting wound healing and optimal recovery. By understanding which foods promote tissue repair, strengthen immune response, and reduce inflammation, patients and caregivers can take the necessary steps to protect both the process and the patient’s health.
