Parkinson's disease is categorized as a degenerative ailment of the central nervous system, wherein a progressive deterioration of nerve cells occurs, leading to impaired movement and other symptoms such as muscular rigidity, resting tremors, or balance disturbances.
Nutrition in Parkinson's Disease
Research indicates that the efficacy of this medication is significantly influenced by dietary factors, specifically the total protein intake and its distribution across meals. During the early stages of the disease, patients should avoid consuming large amounts of protein before taking the medication. Prolonged levodopa therapy may result in various adverse effects, including reduced treatment efficacy, balance disorders, autonomic disturbances, cognitive slowing, and sudden fluctuations in mobility. Patients are advised to limit daily protein intake to 0.8–1.0 g per kilogram of body weight. Controlled protein intake helps minimize symptom fluctuations, prevent treatment-resistant phases, enhance mobility, and improve overall well-being. The distribution of protein across meals depends on the patient's lifestyle and disease progression.
Balanced protein distribution diet
The balanced protein distribution diet involves evenly distributing the daily protein intake across multiple meals while maintaining a carbohydrate-to-protein ratio of 5:1 or 6:1. This dietary approach is particularly recommended for individuals with less pronounced fluctuations in physical activity who are more active in the evening. The patient should consume five meals per day, each of which should include vegetables, fruits, and small amounts of olive oil, oil, and butter.
A diet with controlled protein distribution
The protein redistribution diet involves consuming the majority of the daily protein intake in the evening hours. Throughout the day (from morning to late afternoon), the total protein intake should not exceed 7–10 g (about 10% of the daily protein requirement). This necessitates the use of low-protein cereal products. Patients should consume a high-protein dinner and, approximately one hour later, a high-protein dessert. This diet is recommended for individuals with acute metabolic fluctuations and morning activity. In practice, it is easier to implement a protein distribution diet as it does not require significant dietary restrictions. However, it is less effective than a diet with protein redistribution. Before making such a drastic dietary change, it is essential to consult a physician, as an improperly balanced diet can lead to nutritional deficiencies and malnutrition. Patients following a diet with controlled protein content should remain under constant supervision of a dietitian and physician.
