Nutrition is just as important as going to your doctor or wound care nurse in order to optimize wound healing. There are 6 primary nutritional needs that can aid in wound healing and fight infection:
Calories
Fluid
Protein
Zinc
Vitamin A
Vitamin C
If you have diabetes, fluid restrictions or renal disease, talk to your doctor or registered dietitian before making diet changes.
Calories
Calorie needs are typically 14-16 calories per pound per day when healing. Your
body needs extra calories (energy from food) while your wound heals.
If your appetite is poor, consuming smaller, more frequent meals that include calorie-dense food items may be beneficial. Get nutrition from a variety of food groups, and
keep healthy snacks on hand.
If you continue to lose weight unintentionally, talk to your dietitian about higher calorie
snacks/meal ideas.
Fluid
Fluid needs are typically 1 ml per calorie daily. Adequate fluid is important to
keep skin healthy. Some examples of fluid are:
Water
Milk or fortified soy beverages
100% fruit or vegetable juice
Soup or broth
Coffee or tea
Water is the best choice for obtaining fluids. Aim for 9-12 cups of fluid per day.
If your appetite is poor, whole milk or smoothies are calorie-dense fluids you can drink. If you have diabetes, avoid sugary beverages in order to control blood sugars.
Protein
Protein needs are typically 0.54-0.68 grams per pound in body weight daily. Protein is important because it helps build and maintain muscle, heal tissue and have a healthy immune system. Try to have at least one protein source at each meal and snack such as:
Meat, poultry, fish
Eggs
Cheese
Cottage cheese
Yogurt (Greek is highest in protein)
Tofu
Milk or fortified soy beverages
Zinc
Zinc is a mineral mostly found in animal foods. Examples include:
Eggs
Fish
Legumes (beans, lentils)
Liver
Meat
Milk
Nuts and seeds
Poultry
Seafood (oysters, crab, clams)
Whole grain foods (brown rice, cereals, oatmeal, barley)
Vitamin A
Vitamin A is found in animal foods and brightly colored fruits and vegetables. Examples include:
Apricot
Cantaloupe
Carrots
Cheese
Eggs
Leafy greens
Liver
Mango
Milk
Papaya
Pumpkin
Sweet potato
Vitamin C
Many vegetables and fruits are high in vitamin C. Eat more bright red, orange and green vegetables and fruits such as:
Broccoli
Brussels sprouts
Cantaloupe
Kiwi
Papaya
Potato with skin
Strawberries
Sweet bell pepper
Tomatoes
100% fruit juice
Diabetes and Wound Healing
Proper blood sugar control is very important for wound healing. Remember to limit sugary foods and to aim for at least half of carbohydrates to be whole grains. Speak
with a dietitian if you need assistance with nutrition for blood sugar control.
Blood sugar guidelines:
Before meals: 80-120 mg/dL
1-2 hours after eating: Less than 180 mg/dL
A1C: Less than 7.0%
Other Wound Healing Tips
It may be beneficial to add protein powder to beverages/meals to get enough protein.
Take a multivitamin if your diet seems like it’s lacking in various food groups.
Older adults (>70 years old) especially could benefit from protein supplements or
multivitamins due to lower calorie needs and decreases in appetite.
Remember to ask your doctor or registered dietitian if you have other conditions that have some dietary restrictions (diabetes, renal disease, heart failure, etc.) in order to find the right diet plan for you.
