Foods that contain dopamine

This week we learned that Parkinson's disease is caused by a lack of dopamine.  The dopamine provides us with muscle control.  The dopamine producing cells are found in the midbrain known as the substantia nigra.  I looked online and found a couple of foods that contain dopamine (website below).  Beans, sunflower seeds, bananas, and nuts all have dopamine.  Eating these foods may help prevent Parkinson's and slow down the disease once it is diagnosed.  I have heard that walnuts are good for the brain, and coincidentally look like a brain.
