To facilitate the body’s innate ability to heal itself is a principle of Naturopathic Medicine. As Naturopathic Doctors, we are taught to abide by the healing power of nature – vix medicatrix naturae. Under this understanding, Naturopathic Doctors use the therapies in our toolbox such as nutrition, vitamins, herbs, homeopathy, lifestyle counseling, manual therapies, and energy work to manifest and augment the normal healing response of the body. Doing so promotes wellness, health, stamina, strength, beauty and even ever-lasting youth. NDs also focus on removing obstacles to cure that impede the patient’s chance for wellness. In a nutshell, NDs treat the root cause so the branches of health can bud then bloom.
Do we heal automatically?
While we assume healing to be a natural in-born process, we also have to consider each individual’s chance for wellness. One’s nutrition cannot be separated from this. Nor can the strains placed on this natural process be excluded from each individual’s current nutritional health status. General government-approved nutrient requirements are based on a 2000 calorie daily diet for a healthy individual, and yet a higher percentage of unhealthy Americans are consuming 50-100% more calories daily, doubling their basic nutrient demands. As of 2014, the Center for Disease Control reports that 69% of Americans are overweight or obese1. Overweight and obese individuals face higher nutrient demands, increased risk for oxidative stress and chronic illness, which place them at a deficit in their healing capabilities. Currently, 77% of the American public take at least one pharmaceutical medication. Several commonly prescribed pharmaceuticals have been shown to accentuate the healing deficit such as Statins for high cholesterol1, Vasopressors2 such as Sudafed and Epinephrine and Glucocorticoids3 such as Prednisone and other corticosteroids, to name a few.
Nutrition for Wound and Injury Care
Immediately following injury, or with any chronic wound, it is essential to increase overall calorie intake to 50% more than Energy Expenditure2. Daily energy expenditure can be calculated with the following formula, using data that most any individual can learn based on their basal metabolic rate (BMR, Stress Factor, and Physical Activity Level).
Energy Expenditure = BMR x stress factor x physical activity4.
Normally, the body’s energy pathway is fueled almost completely by carbohydrates and fat but in the case of wounds, this is not so. While increasing overall caloric intake is essential, chronic protein intake is more powerful than calorie intake in modulating growth promoting factors, such as circulating IGF-1 concentrations5. Previous protein requirements of 1.4 g/kg of body weight/day in wound care patients have been under-estimated. Compared to the average American male who is consuming >1.34 g/kg/day or 40% of his calories from protein, a wound patient may need to consume much more. One study showed significant healing, measured by pre-albumin and healing outcomes, in tube-fed wound care patients when protein was increased to 1.85g/kg of body weight/day over a one year period6. Glucose and fatty acids have also been shown to play a role in the wound healing response. Glucose deficiency will cause the alanine shunt to stimulate glucose synthesis thereby creating a host preference over wound, promoting healing deficit4. Whereas, protein wasting is inhibited by agents such as EPA fatty acid (and infliximab, a TNF-α inhibitor)4. Counteracting weight loss and anorexia in cancer patients is possible with central and peripheral appetite stimulants and nutritional supplements (Omega 3 fatty acids and essential amino acids) as well as correction iron-deficiency anemia7.
Here are some other associations between micronutrient demand and wound healing.
|Micronutrient||Wound Repair Activity|
|Vitamin A||A stimulant for onset of wound healing process, epithelial repair and fibroblast deposition of collagen.|
|Vitamin C||Necessary for collagen synthesis|
|Vitamin D3||Supplementation leads to fibroblast healing in HIV positive teens under antiviral treatment8.|
|Copper||Cofactor for connective tissue production and collagen cross-linking.|
|Iron||deficiency leads to cachexia/wasting in cancer patients, increases risk of morbidity7.|
|Iron||Correcting iron-deficiency anemia reverses uncontrolled cachexia in cancer patients|
|Manganese||Collagen and ground substance synthesis|
|Phosphorus||Supplementation secondarily increases circulating fibroblast growth factor 23 and stimulates Parathyroid Hormone9|
|Zinc||Co-Factor for collagen and other wound protein synthesis|
These principles will apply with all injury to the body, even those that don’t come from accident, injury or burn. Sources of wounds consider are: accident, post-surgery, illness, medication side effects and iatrogenic nutrient depletions, heavy metal or pesticide exposure, SAD Diet and other poor food choices, smoking, excessive alcohol consumption, and chronic inflammation.
Epigenetics and Wound Healing
Epigenetic research on wound healing respond is lagging, however, it is known that epigenetic regulatory mechanisms are essential for skin regeneration, barrier protection, deregulation of repair genes and to control reparative gene expression in epithelium and mesenchyme10. Research also suggests that Nrf2 transcription factor, a novel target of keratinocyte growth factor action, regulates gene expression for the acute healing phase and inflammation in the chronic healing skin wound11. Applying superfoods knowledge to the epigenetics/nutrigenomics of cellular repair is a good clinical approach at this time, as is increasing food sources of required macro and micro nutrients.
Obstacles to Healing
According to Dr. Robert Demling of the Harvard Medical School Burn and Trauma Center, in his paper Nutrition, Anabolism, and the Wound Healing Process: An overview, optimum nutrition is well recognized to be a key factor in maintaining all phases of wound healing4. Nutrition is required to regulate anabolic and catabolic processes. Post injury, it’s been shown that calories from protein are most important for sparing the Lean Body Mass (LBM). Optimized healing is directly dependent on the intake versus the bodily breakdown of protein. Maintaining LBM, primarily via protein nutrition is directly associated with healing and even survival. Protein Energy Malnutrition (lack of dietary protein) is cited as one of two major obstacles to cure in wound healing. When 10% of LBM is lost complications can result in wound healing. Once LBM is lost by more than 15% the body will no longer prioritize the wound and will work to save LBM instead, which means chronic and non-healing wounds will persist. Chronic wounds are more complicated because the biology of the healing process is significantly altered. If 30% of LBM is lost then spontaneous ulcers will occur, and morbidity is likely. LBM of less than 40% means death. The body will use all available energy resources to prevent death. Fat calories cannot be used to prevent PEM or loss of LBM. Luckily when LBM is restored, the rate of healing is directly correlated with rate restoration of body mass.4
Activation of the stress response to injury is the second reason for a non-healing wound. The more stress with an injury, the more obstacles to healing. While the stress response is activated with any wound, existing PEM will accentuate its net healing deficit. The stress factor increases with the intensity of the stress insult indicted by the wound. A minor injury, minor surgery, bone fracture, and a clean wound would increase the stress factor at 1.2 whereas as infected wound, a major trauma, or severe burn would increase the stress factor to 1.54.
Naturopathic Medicine abides by the body’s natural ability to heal itself, while also treating the individual. Each one of us can be assessed for our own healing potential so proper treatment can be applied in any context of wound care.
