Study: Omega-3 Doesn't Improve Memory

Posted: Updated:

New research is casting doubt on whether foods rich inomega–3 fatty acids, such as salmon and nuts, can preserve your memory as youage.

Researchers from Iowa followed more than 2–thousand womenages 65 and older for an average of six years. They found no relationshipbetween the level of omega 3 fatty acids in the women's blood and theircognitive ability as they got older.

But experts say the study is limited because it only measuresomega 3 levels in the bloodstream.

Dr. Peter Whitehouse at University Hospital Case Medical Centerauthored the study.

"You cannot conclude from this study that having omega 3in your diet is not important for your brain health and for your body health aswell," he says.

The researchers themselves say people shouldn't change theirdiets because of their study.

They say fish and nuts are still good for you.

"They are important for practically all aspects of bodyhealth particularly heart it may also affect other things like risk for cancers,"says Dr. Whitehouse.

Experts say fish and nuts are a good alternative to red meatand full–fat dairy products, which are high in saturated fats.

The women in the study were part of the Women's HealthInitiative clinical trials of hormone therapy.
