Turmeric

Turmeric, a cousin of ginger, is one of the principal spices in curry powder. Turmeric is especially rich in curcumin, a compound believed to inhibit Alzheimer’s disease in multiple ways according to experts at the University of California Los Angeles Alzheimer’s Disease Research Center. Not only does it block the formation of beta amyloid plaques, it also fights inflammation and lowers artery-clogging cholesterol which can reduce blood flow to your brain.
