Frequently Asked Questions

20. Can diet help with Parkinson's disease?

At this time there are no specific vitamins, minerals, or other nutrients that have any proven therapeutic value in Parkinson's disease. Studies are being conducted to find out if caffeine, antioxidants, nicotine, and other dietary factors may help prevent or treat the disease because research has suggested that these factors may be important.

While there is currently no proof that any specific dietary factor is beneficial, a normal, healthy diet can promote overall well-being for people with Parkinson's disease, just as it would for anyone else. A high protein meal, however, may limit levodopa's effectiveness because for a time afterwards less levodopa passes through the blood-brain barrier.
