Advise patients with Parkinson's disease (PD) to consume a balanced diet, with special attention to adequate intake of dietary fiber, fluids, and macro- and micronutrients. Regularly reassess patients' nutritional history and anthropomorphic measures (height and weight), particularly in patients with advanced disease. PD-related psychosocial as well as physical and cognitive limitations increase susceptibility to subacute and chronic malnutrition. Nutritional requirements may change with PD progression or after surgical therapy for PD. Patients and caregivers may benefit from counseling by a dietician who is knowledgeable about the nutritional risks and needs of PD. Regularly inquire about dysphagia symptoms, and consider speech therapy consultation for clinical and modified barium-swallowing evaluations and management recommendations. Although non-oral delivery options of dopaminergic therapy are increasing, severe dysphagia may warrant percutaneous endoscopic gastrostomy tube placement for nutritional support and more reliable PD medication dosing. Analyze vitamin B(12) and D concentrations at regular intervals. Both vitamins are frequently deficient in elderly persons but may not be routinely checked by primary care physicians. Record over-the-counter and nutritional supplement medications at each visit, and assist patients in periodically re-evaluating their potential benefits, side effects, drug interactions, and costs. To date, clinical trials of antioxidant vitamins and nutritional supplements have provided insufficient evidence to support routine use for PD in the clinic. Data from several clinical trials of antioxidant vitamins/nutritional supplements are expected in the near future. Consider altering medication dosing in relation to meals to help with mild to moderate motor fluctuations. Patients with severe motor fluctuations may benefit from adapting the 5:1 carbohydrate-to-protein ratio in their daily meals and snacks. Following a "protein redistribution" diet is logistically more difficult and less palatable, and therefore less frequently recommended. To ensure adequate protein intake, a registered dietician should supervise patients who follow either of these diets.
