简要总结
In this prospective, intervention study, participants with diagnosed Parkinson's disease will be instructed to follow a Mediterranean diet for five weeks. Gut permeability will be assessed using food-grade sugar molecules. Participants will provide urine and stool samples to assess gut permeability and microbial communities.

结局指标
主要结局
Gastroduodenal Permeability
时间窗: Week 1; Week 5
The primary outcome is the change in gastroduodenal permeability induced by the Mediterranean diet. Gastroduodenal permeability will be assessed by measuring sucrose concentration in the 0 to 5-hour urine collection (end of intervention minus baseline)
次要结局
- Stool Frequency(Week 1; Week 5)
- Gastrointestinal Symptoms(Week 1; Week 5)
- Whole Gut Permeability(Week 1; Week 5)
- Colonic Permeability(Week 1; Week 5)
- Stool Consistency(Week 1; Week 5)
- Small Intestinal Permeability(Week 1; Week 5)
