High Fiber in Parkinson's Disease
Study Details
Study Description
Brief Summary
The purpose of the research is to determine the effects of a high-fiber nutritional supplement (HFS) on the bacteria, viruses, and fungi that live in different regions of the body in those with Parkinson's disease (PD). We will compare the bacteria, viruses, and fungi of those with PD to those without PD (healthy controls). We will also examine the effects of transplanting stool from humans into laboratory mice with or without Parkinson-like pathology to understand how the microbiome influences the brains of animals. We can use this information to get a better understanding of how changing the microbiome might help humans.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Parkinson's patients Parkinson's patients who will receive a high fiber supplement |
Drug: High Fiber supplement
The supplement consists of a mixture of soluble fibers (from inulin and fibersol-2) and insoluble fibers (from oat bran, corn bran, wheat bran and sorghum bran) and it will be consumed as a drink.

| No Intervention: Control subjects no supplement will be given |
