Iowa Study Finds Omega-3s May Not Help Thinking Skills After All

Contrary to earlier studies, new research led by University of Iowa investigators suggests that omega-3 fatty acids may not benefit thinking skills. The study is published in the September 25 online issue of Neurology, the medical journal of the American Academy of Neurology. Omega-3s are found in fatty fish, such as salmon, and in nuts. “There has been a lot of interest in omega-3s as a way to prevent or delay cognitive decline, but unfortunately our study did not find a protective effect in older women. In addition, most randomized trials of omega-3 supplements have not found an effect,” says study author Mr. Eric Ammann, a doctoral student in the University of Iowa College of Public Health department of epidemiology.
