Diet's role in fighting vitiligo highlighted in new research

By Hugo Francisco de SouzaMar 13 2024Reviewed by Susha Cheriyedath, M.Sc. In a recent review published in the Journal of Cosmetic Dermatology, researchers collated available literature exploring the impacts of diet and nutritional interventions against vitiligo. Their dataset comprised 14 publications from three online scientific databases.

What is vitiligo, and what do we know about its pathology? Vitiligo is a rare autoimmune disorder characterized by the loss of skin pigmentation in patches or blotches, usually around the mouth, hair, and eyes. It is estimated to affect between 0.004% and 2.28% of the global population, and while phototherapy and pharmacological interventions can reduce symptom visibility, no cure for the condition hitherto exists.

About the study In the present review , researchers discuss up-to-date outcomes from studies and publications exploring the association between diet and vitiligo. Two independent reviewers collected papers from three online scientific repositories, namely PubMed, European PMC, and Google Scholar, using repository-optimized search strategies for publication acquisition and screening.

Related StoriesThe Critical Appraisal Skills Programme tool was employed to assess the quality and risk of bias of included publications. Data synthesis comprised outcomes categorization and consolidation, followed by their visual representation as pie charts or bar diagrams. "In a pilot study, the effectiveness of high-dose oral vitamin D supplementation on vitiligo repigmentation was investigated in 16 individuals with vitamin D deficiency vitiligo. Over half of the patients experienced 26%–75% repigmentation after consuming 35 000 IU daily.29 Supplementation is advised but dosing strategies aren't established."
