Abstract

Background

Globally, vegan and vegetarian diets have grown in popularity. At the same time, it is well-known that nutrition plays a critical role in postoperative outcomes, including wound healing. The present investigation undertakes a systematic scoping review of the current literature that explores the impact of vegan or vegetarian diets on wound healing.

Methods

The protocol followed PRISMA-ScR guidelines. PubMed, Web of Science, and Cochrane Library were used to identify articles published until 2024. Studies comparing any wound healing outcome between vegan or vegetarian patients and omnivorous patients were considered eligible. A two-stage screening process was conducted for study selection. Data extraction focused on the primary outcome—any wound healing outcome—and secondary outcomes, which included study general information, laboratory values, limitations, and future perspectives.

Results

Eight studies were included in this review. The majority of publications (87.5%) were prospective studies. Papers reported diverse wound healing outcomes after the following interventions: fractional microneedle radiofrequency, laser surgery, microfocused ultrasound, narrow-band ultraviolet B phototherapy, ultrapulsed CO2 resurfacing, excisional biopsy, skin graft, and photodynamic therapy. In almost all studies (87.5%) wound healing outcomes were statistically inferior in vegan or vegetarian patients compared to omnivorous patients.

Conclusion

Our results suggest that wound healing outcomes may be suboptimal in patients adhering to vegan or vegetarian diets, indicating that these dietary patterns might contribute adversely to the wound healing process. Future research is needed to understand better the underlying mechanisms and the potential implications in the preoperative assessment and postoperative course of these patients.
