Video: Omega-3 May Boost Memory

Could omega-3 fatty acids help preserve your memory and prevent Alzheimer's?

Salmon for Omega-3

Remembering to add some omega-3 fatty acids to your diet may help preserve your memory later in life. A new study finds eating foods containing omega-3s — like fish, chicken and nuts — may lower blood levels of a protein called beta-amyloid, which is often linked to Alzheimer’s disease.

Carolyn Snyder, RD, LD, did not take part in the study but offers insight.

“Diet does matter, but it matters sooner than we might have expected,” she says. “This should be implemented as part of your early meal plan.”

Columbia University Medical researchers, in New York, studied the effects of omega-3s on more than 1,200 people age 65 and older. Blood tests and diet questionnaires were used to determine what type of diet each person ate and the amount of beta-amyloid in their blood. Results show the more omega-3 fatty acids a person took in, the lower their plasma beta-amyloid levels.

Researchers say, depending how much omega-3 you’re getting, you could lower your plasma beta-amyloid levels by as much as 30 percent. Snyder agrees.

“Starting a good Mediterranean diet — using poly-unsaturated fats, incorporating fruits, vegetables, lean meats, focusing on fish, and a little bit of plant-based diet — is going to be your best defense.”

Complete findings for this study are in the journal Neurology.
