First of all, patients with Parkinson's disease had better eat more fresh vegetables, such as celery, broccoli, cabbage, rape, lettuce and chrysanthemum. Eating these vegetables is very important for patients to keep their stools unobstructed. Because many patients with Parkinson's disease have constipation. Second, patients with Parkinson's disease should pay attention to the intake of high-quality protein to prevent hypoproteinemia. Usually you can drink milk, eat beef and mutton, eggs and so on. But the time to eat protein must be separated from the time to eat levodopa, and it is best to take it one hour after taking the medicine. Third, patients with Parkinson's disease can also eat some nuts, such as walnuts and pistachios. Pay attention to drink plenty of water at ordinary times.
