Summary

This trial will test if a special type of dietary fiber called resistant maltodextrin is safe and can help improve gut health and symptoms in people with Parkinson's disease. The fiber works by feeding good bacteria in the gut.

Who is the study for?
This trial is for men and women aged 60 or older with Parkinson's Disease (PD), who have been on a stable dose of PD medications for at least 30 days. They should be in the early to mid-stages of PD and not have diabetes, unstable health conditions, recent laxative use, cognitive impairment, or be taking certain other treatments.
What is being tested?
The study tests the safety and effects of resistant maltodextrin, a dietary fiber, on gut health and Parkinson's symptoms compared to regular maltodextrin. Participants are randomly assigned to one of these two groups to see if there are any differences.
What are the potential side effects?
While specific side effects aren't listed here, typical concerns with dietary fibers like resistant maltodextrin may include digestive discomfort such as bloating, gas or altered bowel habits.

Other Research
Common dietary modifications like the low FODMAP diet and resistant starches, such as resistant maltodextrin, work by altering the gut environment to reduce gastrointestinal symptoms. The low FODMAP diet limits fermentable short-chain carbohydrates that cause bloating and pain, while resistant starches enhance the production of beneficial microbiome-derived metabolites, improving gut health. These approaches are important as they provide non-drug options to manage symptoms and enhance the quality of life for patients with functional gastrointestinal disorders.
Ingestion of resistant starch by mice markedly increases microbiome-derived metabolites.
