Lifestyle Changes

No special diets or natural foods have been shown to slow down the progression of Parkinson's disease, but there are some dietary recommendations.

Protein. High levels of proteins compete with levodopa for transport to the brain and reduce its effectiveness. Avoiding protein altogether is not the solution, since malnutrition can result. Most experts now recommend trying to maintain a carbohydrate-to-protein ratio of 7:1 throughout the day. This may be difficult to calculate and some physicians recommend simply keeping proteins to 12% of total daily calories.

As an aid in calculation, it may be helpful to note that food labels indicate proteins in grams and that one gram of protein equals four calories. Good control of protein intake may help minimize fluctuations and wearing-off and may allow some patients to reduce their daily levodopa dosage.

Restricting Calories. Animal studies indicate that reducing calorie intake may help reduce toxic effects on nerve degeneration.

Fruits and Vegetables and Increasing Fiber. Eating whole grains, fresh fruits and vegetables is the best approach for any healthy life. A diet rich in fruits and vegetables may help protect nerve cell function. Many of these foods are also often rich in fiber, which is particularly important for helping to prevent constipation.

Dietary fiber is the part of food that is not affected by the digestive process in the body. Only a small amount of fiber is metabolized in the stomach and intestine, the rest is passed through the gastrointestinal tract and makes up a part of the stool. There are two types of dietary fiber, soluble and insoluble. Soluble fiber retains water and turns to gel during digestion. It also slows digestion and nutrient absorption from the stomach and intestine. Soluble fiber is found in foods such as oat bran, barley, nuts, seeds, beans, lentils, peas, and some fruits and vegetables. Insoluble fiber appears to speed the passage of foods through the stomach and intestines and adds bulk to the stool. It is found in foods such as wheat bran, vegetables and whole grains. Fiber is very important to a healthy diet and can be a helpful aid in weight management. One of the best sources of fiber comes from legumes, the group of food containing dried peas and beans.

People whose diets have been low in fiber should increase it gradually. It is best to obtain dietary fiber, soluble or insoluble, in the natural form of whole grains, nuts, legumes, fruits and vegetables. If it proves difficult to do so, psyllium, a grain naturally found in India, is an excellent soluble fiber supplement (Metamucil, Fiberall, Perdiem Fiber). Fluids are particularly important in preventing constipation.
