3 Simple tips to optimise nutrition in Parkinson's

Here are three evidence-based tips to enhance nutrition for individuals with Parkinson’s disease, focusing on common challenges and practical solutions:

Optimize protein timing with your levodopa medications:
Parkinson’s patients often take levodopa, a medication that can compete with dietary protein for absorption in the gut. To maximize its effectiveness, try a "protein redistribution" approach: consume most protein-rich foods (like meat, dairy, or legumes) at dinner rather than throughout the day. Aim to keep protein intake low 30-60 minutes before and after taking levodopa, focusing instead on carbohydrates or vegetables during those windows. This can improve medication efficacy and reduce "off" periods, while still meeting daily protein needs (typically 0.8-1g per kg of body weight).
Boost antioxidant-rich foods:
Oxidative stress is implicated in Parkinson’s progression, so increasing antioxidant intake may help protect brain cells. Incorporate foods high in vitamins C and E, such as berries (blueberries, strawberries), leafy greens (spinach, kale), nuts (almonds, walnuts), and citrus fruits. For example, a small handful of walnuts daily provides vitamin E and omega-3s, which may also support brain health. Avoid overcooking vegetables to preserve nutrients—light steaming is ideal.
Address swallowing and constipation with fiber and hydration:
Parkinson’s can slow digestion and impair swallowing (dysphagia), so focus on soft, nutrient-dense foods and hydration. Add fiber-rich options like oatmeal, chia seeds, or mashed sweet potatoes to combat constipation, a common issue due to reduced gut motility. Aim for 25-35g of fiber daily, paired with 6-8 cups of water, to keep things moving. If swallowing is a challenge, blend fruits and veggies into smoothies or opt for thickened liquids as recommended by a speech therapist.

These tips can be tailored to individual symptoms and preferences—consulting our dietitian who is familiar with Parkinson’s is a great step for personalized advice.
