[Diet in Parkinson disease].
The interest in a protein redistribution diet, also called daytime protein restriction diet, has increased among patients with Parkinson's disease. Since certain amino acids compete with L-dopa in the intestine and at the blood-brain barrier, daytime protein restriction may improve fluctuations in motor ability. However, this diet can contribute to weight loss, nutrient deficiencies and cause cognitive disabilities if the diet is not correctly observed. Further studies are needed to clarify how medication with L-dopa in combination with different diets (relative contributions of protein, fat and carbohydrate) may affect motor fluctuations, nutritional status and cognitive ability.
