Why fish oil is good for youIt's good news that we are living longer, but bad news that the longer we live, the better our odds of developing late-onset Alzheimer's disease.
A number of Alzheimer's scientists have long touted fish oil, by pill or diet, as an accessible and inexpensive "weapon" that may delay or prevent this debilitating disease. Now, UCLA researchers have confirmed that fish oil is indeed a deterrent against Alzheimer's, and they have identified the........Go to the Neurology news blog (Added on 12/25/2007 11:07:10 PM)
