Turmeric

It has been discovered that people in India have a very low incidence of neurological diseases. Researchers have identified turmeric as a spice which may have a protective effect on the brain and nervous system.

Curcumin, the active component of turmeric, works to thwart the progression of demyelinization. It is also a potent anti-inflammatory agent. While the work remains preliminary, it doesn't hurt to add this spice to the daily diet.
