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

Arm Intervention/treatment
RS
Resistant starch supplementation (5 g twice a day)
Dietary Supplement: Resistant starch
No RS
PD patients who do not receive resistant starch, but who receive recommendations concerning healthy Nutrition (based on the guidelines of the German Society for Nutrition)
Other: Recommendation with regard to nutrition
Subjects in this arm will receive General recommendations with regard to nutrition based on the guidlines of the German Society for nutrition



Primary Outcome Measures :
  1. Bowel habits [ Time Frame: 8 weeks ]
    Number of patients with improved bowel habits

  2. Fecal short chain fatty acid (SCFA) concentrations [ Time Frame: 8 weeks ]
    Number of patients with either a) increased, b.) unaltered or c) decreased concentration of short chain fatty acids in fecal samples at 8 weeks (compared to baseline)

  3. Analysis of fecal microbiota composition [ Time Frame: 8 weeks ]
    Analysis to detect changes between baseline and 8 weeks of resistant starch supplementation
