The Mediterranean Diet is considered to be the healthiest diet for reducing cellular inflammation and cardiovascular risk.1 It contains many of the foods that are beneficial for people with Parkinson disease. The food choices in this diet include:

 fresh fruits and vegetables
 whole grains, nuts, and legumes
 lean meats and fish
 olive oil, vinegar, and omega-3 oils
 light to moderate alcohol consumption (check with your doctor first)

Take vitamin D supplements daily  2,000 IU. A recent paper presented a compelling hypothesis about the relationship between vitamin D and brain health, especially related to Parkinson disease.2

Eat foods containing omega-3 oils. Studies have found that these oils are helpful for preventing cancer and cardiovascular disease. One study indicated that they might have neuroprotective qualities.3 The foods with these oils include coldwater, oily fish such as salmon, herring, mackerel, anchovies, and sardines. Other such foods are tuna, flounder, halibut, shark, swordfish, krill, green-lipped mussels, flaxseed, walnuts, pecans, and hazelnuts.
