Curcumin, the chemical found in the curry spice turmeric, could both boost brain power and help prevent the onset of Alzheimer's disease.
A study tested the brain power of more than a thousand Asian people aged between 60 and 93 using a standard test called the Mini Mental State Examination. Those who ate curry even just once every six months had better results than those who said they "never or rarely" ate it.
Previous research has suggested that curcumin inhibits the build-up of the harmful protein deposits called amyloid plaques that occur in the brains of Alzheimer's patients. Curcumin is also reputed to have antioxidant, anti-inflammatory and anti-cancer properties that are still being investigated.
