Brief Summary

There are about one million Parkinson's disease (PD) patients in America. The risks associated with whether or not an individual may develop PD include environment and genetic (biologic, hereditary) factors. Studies have show that certain things may be triggers, for example cells in the brain that are made active and associated inflammation in the brain. The gut is the largest interface between the PD patient and the environment, and it is highly thought to be pathway to the environment trigger. Research studies have looked at how information is passed back and forth between the brain and the gut. The goal of this study (pilot) is to gather information to conduct a larger clinical trial. For this pilot study is to determine if a microbiota-directed (bacteria in the gut) intervention (dietary bar) is capable of correcting the bacteria gut balance in PD. This is based on the thought that an imbalance of bacteria in the gut of PD patients may lead to the gut and intestines working correctly. The long term goal is to see if the intervention has the potential to modify the disease or protect the brain in PD. If the intervention successfully improves the bacterial imbalance in PD, it will be the first attempt to modify the Gut-Brain communication in PD, which can lead to additional studies aimed at improving the disease progression or prevention. In this project, the investigators will test how well Parkinson's disease patients tolerate changes in the gut and intestines by providing the participants a dietary bar to eat for 10 days. The investigators intend to conduct this pilot clinical trial in which the investigators believe that daily oral intake of a "prebiotic" mixture will be safe and well tolerated in a small number Parkinson's disease participants prior to a larger clinical trial looking at efficacy.
