Parkinson's disease does not have any specific dietary restrictions, but the following aspects are recommended for patients:

First, patients should consume more laxative vegetables and fruits, such as spinach, bananas, and celery, which help maintain the motility of the large intestine and promote bowel movements. Since many Parkinson's patients suffer from constipation, these foods can greatly improve their bowel movements and are recommended.

Second, Parkinson's patients can also eat foods that nourish brain cells, such as pine nuts, walnuts, and pistachios.

Third, patients may consume some plant oils, mainly olive oil, which can also play a good regulatory role.

Fourth, Parkinson's patients should be cautious about the timing of protein intake in relation to their medication schedule, to avoid affecting the absorption of the medication.
