Objective: The aim of this study is to evaluate dietary habits and food preferences of PD patients versus healthy controls.

Background: Currently, there is a growing body of evidence suggesting that nutritional habits might be related with the progression and management of Parkinson’s disease (PD).

Method: In this case-control study we assessed nutrient intakes in 82 PD patients and 60 controls.  We used a standardized questionnaire that included extensive food assessment and nutrient intakes, and dietary preferences.

Results: There were 56 men (68%), mean age 68,23±14,38 years [range 53- 84 years]. Among the non-motor features in the PD patients group, the most common were nocturia and gastro-intestinal symptoms. Overall PD patients had lower BMI and lower daily food intake than healthy controls. Comparing with controls, PD patients reported a higher daily intake of the following nutrients: iron (13.4mg/day vs. 11.2mg/day), potassium (4123mg vs. 3456mg), carotene (4124μg vs. 3897μg), and folate (345μg vs 342μg). PD patients have a lower daily intake of vitamin E (15.4 mg vs. 17.6mg) comparing with healthy controls. PD patients consumed less alcohol and fewer calories. PD patients with dysphagia had softer food intake and used to drink less fluid per day. Regarding the diet style, the PD patients showed preferences for aliments belonging of mediterranean diet. Protein intake was correlated with motor fluctuations.

Conclusion: Dietary compounds might pay an important role in patients with PD, and nutritional habits are important, especially in advanced stages.
