Diet Quality and Skin Carotenoid Status in Parkinson’s Disease: A Cross-Sectional Analysis

Year: 2026

Type: article

Abstract: Objectives: Parkinson’s disease (PD) involves the progressive loss of dopamine-producing neurons. Carotenoids, antioxidants rich in fruits and vegetables commonly associated with higher diet quality, may be protective of factors that influence neurodegeneration in PD. The objective of the study is to assess the association between diet quality and skin carotenoid content (SCC) in patients with PD.
