Brain Health and Nuts

A balanced diet is a foundation of good health. For people with Parkinson’s, a balanced diet is even more important. Of all the foods that have been studied for their potential to promote brain health, research into nuts has shown promise.

• Walnuts. Walnuts contain an essential fatty acid called omega 3 and a variety of minerals, which early studies associate with a decreased risk for dementia. Try eating 5 to 10 each day.

• Pistachios. Emerging evidence shows these nuts (the vitamin K and antioxidants in them) may have potential for helping to re-establish lost connections between neurons. They also contain a small amount of lithium, which may help to improve mood. You can eat a few of them two or three times a week.

• Macadamia nuts. Oils in these nuts may increase the production of neurotransmitters that help brain cells communicate with each other. They are high in calories, but a few a day is good for you.

• Cashews. Iron, zinc and magnesium in cashews may boost serotonin — a neurotransmitter linked to good mood — and may reduce memory loss.

• Almonds. Although they have little effect on brain health, almonds contain fibre, which helps relieve constipation (a common symptom in PD).

• Brazil nuts. These nuts contain selenium, a mineral that may have the potential to counteract environmental toxins like pesticides and herbicides. Eat no more than one or two a day.
