Parkinson's disease is a neurological disorder. Neurons in your brain that produce a chemical called dopamine die, leaving you with less dopamine than normal. The lack of the chemical causes you to suffer from motor disorders. A good diet for people with Parkinson's disease can't stop the progression of the disease but can keep your body as healthy as possible as you manage symptoms and receive treatment.
Protein
Protein is an essential nutrient for everyone, including people who have Parkinson's disease. Protein is involved with growth, maintenance and repair of your body's cells and is particularly important for maintaining balance and strength that is affected by Parkinson's disease. Protein can interfere with certain Parkinson's medications, such as levodopa. Levodopa helps control tremors and muscle spasticity associated with the condition. Take medications at least 45 minutes before you eat a meal containing protein to ensure the effectiveness of the drug. The U.K.-based Parkinson's Disease Society explains that some Parkinson's patients may need to take medications early in the day and consume their protein-rich meal in the evening to prevent drug interactions. Meats, fish, beans, eggs, yogurt and nuts are good sources of protein.
Fiber
Constipation is a common side effect of Parkinson's disease. The problem stems from some medications as well as the decreased function of the nerves in your gastrointestinal tract. You may crave sweets in response to your condition, reports the Parkinson's Research Foundation; foods that have high levels of sweeteners and fat can also cause constipation. Incorporating fiber in your diet can combat constipation and also keep your blood sugar levels stable. Beans, whole-grain breads, cereals, pastas, rices and a variety of vegetables are rich in fiber. Drink plenty of water to help ease the discomfort of constipation.
Calcium
Calcium is an important mineral in a Parkinson's disease diet because the nutrient keeps your bones strong. Tremors and unsteadiness on your feet can increase your risk of falling and fracturing a bone. Calcium is in a variety of dairy products, but the Parkinson's Disease Society cautions that milk may not be the best source of calcium for some people. Milk causes your saliva to become thicker; if you suffer from dysphagia -- swallowing difficulties -- as one of your symptoms, thick saliva can complicate issues. Eat broccoli, cheese, spinach, pinto beans and tofu to get calcium into your diet.
Vitamins and Minerals
Antioxidants and other vitamins and minerals keep your muscles, nervous system and vital organs nourished and as healthy as possible, which is especially important with people suffering from Parkinson's disease. A colorful array of fruits and vegetables is a healthy way to get a range of vitamins and minerals. Speak to your doctor about supplements if you are underweight and unable to eat these types of foods.
