Parkinson's patients had better eat more cereals, vegetables and fruits, eat foods containing high-quality protein, eat vegetable oil containing unsaturated fatty acids, or choose to drink proper amount of honey or milk. It is suggested that patients with Parkinson's disease maintain a nutritional balance every day, and they can eat appropriate fresh vegetables and fruits every day, and they can choose to eat more dark vegetables. Cooking with fast fire as far as possible can reduce the nutrient loss of vegetables and ensure the vitamins needed by the body every day. Parkinson's patients should insist on eating carbohydrate-containing foods every day, such as rice flour and other staple foods, or choose to eat coarse grains such as sweet potato, sweet potato and yam, as well as miscellaneous grains and potatoes to balance their diet. Moreover, patients with Parkinson's disease should eat more high-quality protein food such as eggs, fish, shrimp and lean meat. A high-protein diet is not conducive to the absorption of anti-Parkinson's drugs, and it is best to eat it at dinner.
