It has been found that among all diabetic foot patients, including those without trauma at level zero, about 60% of patients have different degrees of malnutrition or symptoms of nutritional disorders. Our Sugar Foot Center has been paying attention to nutritional intervention for diabetic foot patients. How to perform nutritional interventions? The nutritional status of the patient does have an impact on the treatment. As we all know, patients eat nutritious foods for their bodies to absorb during illness, such as bone broth for fracture surgery, because an adequate supply of nutrients is beneficial to recovery. Similarly, the treatment of diabetic foot disease is accompanied by continuous and large plasma exudation and protein loss, and hyperinflammatory response of the traumatic tissue and even the whole body. Such patients need protein and other energy-supplying substances to supplement, because the recovery of the trauma, cell proliferation, tissue proliferation, etc. all need a lot of nutrition, and when the patient is nutritionally deprived, it will often slow down the treatment, and the trauma tends to recover slowly. In terms of dietary interventions, we conduct scientific assessments of patients in terms of nutrition, formulate corresponding nutritional treatment plans based on the results, and supervise and guide patients in their implementation. For example, most of the diabetic foot patients are nutritionally deficient in protein, we will let the patients stew some bone soup, pigeon soup, chicken soup type of nourishing soup in the cafeteria to replenish the protein needed by the body in time. Of course, protein intake is also determined by the patient’s condition, for example, patients with combined kidney impairment should not be blindly supplemented, and the intake of plant-based proteins such as beans should be reduced. Diabetic foot is a localized infection caused by viral erosion due to low autoimmune function. It is also a lifestyle disease of its own, i.e., food-borne and medical-borne, and genetics is not the main cause of its development. Therefore, infection control, balanced diet, and rational use of nutritional interventions are key to the treatment of diabetic foot. In conclusion, reasonable dietary nutrition is very crucial in the treatment of diabetic foot, and the source of everything in the body is in the nutritional support, so patients need to follow the medical advice to serve and arrange a balanced nutritional intake reasonably, which is decisive for the recovery of diabetic foot.
