Because researchers have such a limited understanding of the cause of Parkinson’s disease, there are currently no definite ways to reduce your risk of developing this condition.

Some studies have suggested that certain factors can lower your risk of Parkinson's disease. Examples include:

  • Having a higher caffeine intake
  • Having a higher intake of vitamin E and nuts
  • Having a higher intake of unsaturated fatty acids
  • Using of nonsteroidal anti-inflammatory drugs (NSAIDs)
  • Eating a Mediterranean diet, which includes plant foods (eg, fruits, veggies, grains, beans, seeds), olive oil, and fish
  • Regularly engaging in moderate to vigorous exercise

However, these were observational studies. They do not prove a cause and effect relationship for preventing Parkinson's disease. Talk to your doctor before making any changes to your diet or taking any new medicine. The side effects may outweigh any potential benefits.
