What this trial studies

This pilot study aims to assess the feasibility and effects of an 18-month Mediterranean-style diet intervention compared to a standard diet in individuals living with Parkinson's Disease who do not have dementia. Participants will be randomly assigned to either diet group and will receive virtual nutrition coaching and cooking classes, along with regular in-person assessments at the University of British Columbia. The study will monitor changes in gut microbiome and Parkinson's symptoms, utilizing wearable devices to track physical activity and lifestyle factors throughout the intervention period.

Who should consider this trial

Good fit: Ideal candidates are individuals aged 40-80 with a clinical diagnosis of Parkinson's Disease who are cognitively stable and can commit to the study's requirements.

Not a fit: Patients with atypical parkinsonism, significant medical conditions, or those unable to participate fully in the nutrition intervention may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into dietary interventions that may improve symptoms and quality of life for patients with Parkinson's Disease.

How similar studies have performed: While there is existing research linking Mediterranean diets to reduced risk and mortality in Parkinson's Disease, this specific intervention is novel and has not been extensively tested.
