How can my diet help me to manage my Parkinson's symptoms?

If you have Parkinson’s, you may find that simple changes to your eating and drinking habits help you manage your symptoms more effectively, and can improve your general health and wellbeing. 

We explore some of the more common diet issues you may experience, and share tips on how to deal with them.

Constipation

Constipation is a common problem in Parkinson’s. You can ease constipation by drinking more fluid, keeping active, and eating fibre-rich foods. If these don’t help, your doctor may suggest laxatives.

Low blood pressure

People with Parkinson’s can experience changes to their blood pressure, sometimes related to their medication. Low blood pressure symptoms include feeling dizzy, weak or confused and are more likely after large meals (as blood goes to your stomach for digestion) or
when you’re dehydrated.

You may find it helps to avoid large meals and reduce your carbohydrate intake (especially sugary foods). Stay hydrated by increasing your fluid intake and reducing the amount of
alcohol you drink.

Poor bone health

Many people with Parkinson’s have poor bone health and low levels of vitamin D.

You can improve bone health by increasing your intake of calcium and vitamin D. Much of your vitamin D comes from the sun but you can boost it by eating oily fish, cereals, eggs and red meat.

Maintaining a healthy weight

Swallowing problems and dyskinesia can lead people with Parkinson’s to be underweight. Try to eat three meals a day and snacks in-between. You can also add extra cream, butter or honey to foods.

Some people with Parkinson’s find that it’s harder to be active and so they gain weight instead. Try boiling, grilling, baking or steaming foods rather than frying and cut down on high fat, sugary foods. Your GP or dietitian can advise on a suitable diet for you.

Protein and medication

Protein can interfere with some Parkinson’s medications, such as levodopa.

You can avoid this by taking your medication 30-45 minutes before or after eating a large meal.
