Fact sheet: Nutrition

Nutrition plays an important role in supporting people living with Parkinson’s. While there isn’t a single “Parkinson’s diet,” research continues to explore how gut health, balanced eating, and nutritional status can influence symptoms and overall wellbeing.

This nutrition fact sheet highlights how common Parkinson’s symptoms such as fatigue, constipation, reduced appetite, and changes in taste can affect nutrition and day‑to‑day life. It also explains why maintaining a healthy, balanced diet is important for managing weight, supporting energy levels, and helping medications work effectively.

You’ll learn about:

  • The connection between gut health, the microbiome, and Parkinson’s
  • Practical ways to manage constipation and support digestion
  • Maintaining bone health, including the role of calcium and vitamin D
  • How to manage unplanned weight changes
  • The relationship between protein and Parkinson’s medication timing

The fact sheet also includes simple strategies such as staying hydrated, eating a variety of foods, planning regular meals and snacks, and seeking guidance from a dietitian where needed.

For people living with Parkinson’s, nutrition needs can change over time. Having access to clear, reliable guidance can help you make informed choices and feel more confident managing everyday challenges.
