Nutrition can play an important role in the treatment of chronic wounds; however, it is often overlooked as part of wound care. Diet therapy is not currently part of standard care for diabetic foot ulcers (DFU), though some research has shown that nutrition can support healing. A new study by , assistant professor in the Department of Nutrition and Food Studies, further supports nutrition intervention to improve clinical outcomes.聽聽

Basiri鈥檚 new study suggests that dietary recommendations should prioritize proper wound healing for individuals who are overweight/obese with DFUs. Proper wound healing can be prioritized by recommending that patients consume adequate energy sources and essential nutrients, according to the study.聽

鈥淩outine visits with a dietitian are essential for assessing the dietary needs of patients with diabetic foot ulcers and designing individualized nutrition therapy, which can result in effective clinical outcomes,鈥 said Basiri, the principal investigator. 鈥淚dentifying the adequate dietary intake of macro- and micronutrients in these patients, especially for those who are overweight or obese, is critical for expediting the wound-healing process and can make a substantial difference to medical expenses and quality of life in this population.鈥澛

To the researchers鈥 knowledge, this is the first study that evaluates the effects of nutrition education and supplementation with extra calories, protein, and micronutrients on long-term blood glucose control and body composition in patients who are overweight and obese with DFUs. In addition to standard DFU care, the treatment group was asked to consume more low-fat protein sources, vegetables, and high-fiber carbohydrates, and a lower amount of simple carbohydrates; educated about and given examples of healthier food items; and provided a nutritional supplement to take twice a day.聽

On average, patients in the treatment group lost less lean body mass (8.4 lb. vs. 10 lb.) and gained less fat (2 lb. vs. 8 lb.) than the control group. Additionally, DFUs healed 12.85 times faster in the treatment group than in the control group, and inflammation significantly decreased in the treatment group. Previous research by Basiri found that nutritional education and supplements reduced inflammation in DFUs. The research team suspects that Basiri鈥檚 previous research, along with previous studies reporting that preventing the loss of lean body mass leads to faster healing of chronic wounds, could be why the treatment group healed quicker.聽聽

The findings of this study showed that supplementing a patient鈥檚 diet with extra energy sources and nutrients had positive effects on body composition and phase angle (an indicator of cellular health) and did not have any significant negative effects on long-term blood glucose control when combined with nutrition education.聽聽
