Nutrition in PD

There is no one recommended way to eat with Parkinson's disease (PD).  A balanced diet full of fruits and vegetables, along the lines of the Mediterranean diet, promotes health and well-being for everyone.  The first step in addressing some PD symptoms, like constipation, low blood pressure and swallowing difficulties, involves adjusting your diet.  

The dopamine replacement medications (levodopa) is a building block of protein, so it competes for absorption with other proteins in the digestive tract. Taking levodopa with high-protein meals may reduce how much of the drug gets into your system and how well a dose works.  If you find your dopamine replacement medications isn't working as well as it used to, try taking the medication half hour before, or an hour after, a meal.

These resources will help you understand the recommended nutritional guidelines for those with PD, and why.

The Emerging Role of Nutrition in Parkinson’s Disease

By Stacey E. Seidl, et. al.  Published in Frontiers in Aging Neuroscience, March 7, 2014

This article reviews and summarizes studies that have addressed the role nutrition plays in both neuroprotection and neurodegeneration.  Epidemiological and biochemical studies suggest that inclusion or exclusion of certain food groups may elicit neuroprotection (those containing omega-3, vegetables, fruits, carotenoids, genistein, tea, caffeine, resveratrol) or neurodegeneration (milk).  Foods containing MUFA, PUFA, saturated fat, vitamin C, D, and E, riboflavin, carbohydrates, and meat have conflicting results and need to be studied further.
