Does diet play a role in Vitiligo? Study finds out
In a recent study published in the Journal of Cosmetic Dermatology, researchers combined available data to explore the impacts of diet and nutritional interventions against vitiligo.
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 currently exists. Heightened concentrations of reactive oxygen species (ROS) in tandem with reduced efficacy of the body's normal antioxidant mechanisms is assumed to substantially exacerbate the disease.
As is the case in other chronic conditions characterized by altered ROS metabolism (some cancers and neurodegenerative conditions), diets are being explored for their potential antioxidant properties.
In the study, researchers discussed up-to-date outcomes from studies and publications exploring the association between diet and vitiligo. Two independent reviewers collected papers from online scientific repositories, while in another 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.
