How could diet affect diabetic foot ulcers?

Because there is limited evidence on diet and diabetic foot ulcers, the American Limb Preservation Society (ALPS) recommends a diet with adequate fluids, energy, protein, carbohydrates, fat, and micronutrients (i.e., Zinc, Vitamin C, Vitamin D, and Vitamin E) to facilitate proper wound healing. People with diabetic foot ulcers, like other wound patients, have higher energy and macronutrient needs. The ALPS guidelines therefore recommend foods rich in the aforementioned micronutrients with an intake of 30–35 kcal per kilogram of body weight, 1.25–1.5 grams of protein per kilogram of body weight, and 25-35 mL of fluid per kilogram of body weight daily. Carbohydrate and fat intake should be individualized to the person’s current level of diabetes control while supporting their overall energy needs.
