Patients with Parkinson's disease should pay special attention to their diet. It is recommended that the food eaten by Parkinson's patients mainly includes the following types: First, patients can eat more fresh cabbage, vegetables, celery, and fruits such as apples, oranges, bananas, and tangerines, because these fruits and vegetables help supplement some vitamins. Vitamins have an antioxidant stress effect, which may play a role in preventing the further development of Parkinson's disease. Additionally, these foods can supplement water, promote gastrointestinal motility, and alleviate constipation, which is beneficial for the constipation caused by Parkinson's disease. Second, people with Parkinson's disease can eat more walnuts or black sesame seeds, as well as some other nuts, as these foods also nourish brain cells. Moreover, patients with Parkinson's disease must ensure a balanced diet that includes a variety of grains, such as rice, millet, corn, and sorghum, which are all consumable.
