Nutrition

Nutrition is the science of how food and drink affect health, growth, and body function.

It covers macronutrients (carbohydrates, proteins, fats) and micronutrients (vitamins, minerals) that fuel the body and maintain systems like the brain, muscles, and digestion.

Research suggests that the foods you choose are associated with the rate of Parkinson’s progression, making your diet an easy way to take an active and positive role in your wellbeing journey. Thinking about your diet is not about sticking to strict rules but about making informed choices each time you eat that help you feel better and care for your body and brain.

How nutrition can help Parkinson’s

• Medication absorption: Protein-rich foods can interfere with levodopa (a common PD medication). Adjusting meal timing — e.g., taking medication 30–60 minutes before eating — can improve effectiveness.
• Constipation relief: High-fiber foods (whole grains, fruits, vegetables) and adequate hydration help manage one of the most common Parkinson’s symptoms.
• Bone & muscle health: Calcium, vitamin D, and protein support strength and reduce fall risk.
• Energy & mood: Balanced meals with complex carbs, healthy fats (like olive oil, nuts, fish), and antioxidants (berries, leafy greens) can boost energy and reduce oxidative stress.
• Slowing progression: Diets like the Mediterranean or MIND diet, rich in vegetables, fish, legumes, and healthy fats, may help protect brain health and slow PD progression.

How nutrition can hinder Parkinson’s

• Protein timing issues: Eating large amounts of protein at the wrong time can reduce medication absorption, leading to worse motor symptoms.
• Processed foods: High sugar, saturated fats, and heavily processed foods may worsen inflammation and fatigue.
• Dehydration: Not drinking enough fluids can worsen constipation and low blood pressure, both common in Parkinson’s.
• Weight changes: Poor diet can lead to unintended weight loss (due to swallowing difficulties or reduced appetite) or weight gain (from reduced mobility), both of which complicate Parkinson’s management.

Practical Tips

• Eat small, balanced meals throughout the day.
• Time protein intake carefully around medication schedules.
• Include fibre and fluids daily to ease digestion.
• Choose whole, plant-based foods over processed options.
• Work with a dietitian familiar with Parkinson’s to tailor nutrition to individual needs.

How do I access supports?

It’s advisable to explore all available pathways to find the support that best suits your individual needs. Look to:

• getting a GP referral to someone with Parkinson‘s experience
• your state-based Parkinson’s organisation for advice
• Ask Izzy https://askizzy.org.au/ to search for local services to access
• private health to see what is covered in relation to consultations and expenses
• DVA, NDIS or My Aged Care plan supports.
