Dietary interventions in Parkinson’s disease: An update

Abstract

Parkinson’s disease (PD) is a progressive neurodegenerative disorder mostly affecting the elderly population. Nutritional status, dietary habits, and physical activity are closely associated with PD clinical symptoms. Based on scientific evidence, lifestyle adjustments are being considered as therapy approaches in various chronic diseases. Dietary modifications are an additional treatment strategy for managing motor and non-motor symptoms in PD. This review focuses on the latest nutritional interventions with protein restriction, Mediterranean and ketogenic dietary modification, probiotic utilisation, and their impact on PD.
