Inadequate folate intake tissue impairs repair process in diabetic foot ulcer: Study
Australia: A lack of adequate folate may negatively impact healing in patients with diabetic foot ulcers, suggests a recent study published in the Journal of Human Nutrition and Dietetics. This implies that wound management of people with diabetic foot ulceration (DFU) should include a regular assessment of dietary intake in order to recognize deficiencies in macro-and micronutrients. Addressing these inadequacies may help to optimize healing.
Individuals with DFU are required to take adequate nutrition, therefore, an assessment of dietary intake is critical. A lack of proper intake of nutrients including protein, zinc, and vitamins C and D have all been related to poor wound healing. However, the comprehensive dietary intake of Australian adults with DFU is poorly understood. Peta Ellen Tehan, University of Newcastle, Callaghan, NSW, Australia, and colleagues, therefore, aimed to describe the dietary intake of adults with DFU in an Australian setting in a cross-sectional study.
For this purpose, the researchers recruited participants (n = 115) with diabetes (type 1 and 2), a mean body mass index of 36, and current foot ulceration from across New South Wales, Australia. Using Australian Eating Survey, a self-reported validated food frequency questionnaire, dietary intake was assessed. The mean reported energy intake was 9.57 MJ day–1.
Based on the study, the following were the study's key findings:
- A mean protein intake of 104 (±SD 49) g day–1 is below recommended intake for wound healing; however, the mean protein intake contribution to energy (19%E) was within recommendations for normal populations.
- The mean carbohydrate intake (43%E) was within recommended ranges for healthy populations; however, the mean total fat intake (36%E) was above recommendations.
- Micronutrient intake was adequate, apart from folate, which was below the recommended intake, and sodium, vitamin C, vitamin A and selenium, which were above the recommended intake.
"A lack of adequate folate may have a negative impact on healing, with folate proposed to play a role in tissue repair," wrote the authors.
"Wound management of individuals with DFU should include a regular assessment of dietary intake to recognize deficiencies in macro-and micronutrients, and subsequently address these inadequacies to optimize healing."
