The Curry Antidote?

Is this true?

Eating a curry once or twice a week could help prevent the onset of Alzheimer's disease and dementia, a US researcher suggests.

The key ingredient is curcumin, a component of the spice turmeric. Curcumin appears to prevent the spread of amyloid protein plaques - thought to cause dementia-in the brain.

But the theory, presented at the Royal College of Psychiatrists' annual meeting, has been given a lukewarm reception by UK experts.

For us in the Orient, eating curry is almost a daily affair so are we really spared from Alzheimer's or is this another wild goose chase propagated by the West?
