NCT02784145

Brief Summary

The investigators will investigate the effects of an 8-week resistant starch (RS) supplementation (5 g twice a day) in patients with Parkinson Disease and matched controls on:

  1. 1.symptoms of constipation (assessed by clinical scores);
  2. 2.fecal short chain fatty acid concentrations (measured by chromatography);
  3. 3.gut microbiota composition.
