Eating Fish May Ward Off Dementia

I read with interest this article in the NY Times about the advantage of eating fish. It says that there is new evidence that a diet rich in fish may ward off dementia and the more fish you eat, the less likely you will get dementia. However, the opposite is true for meat because the more meat you eat, the more likely you are to have dementia. There have been other studies indicating that red meat may be bad for the brain.
