Preventing Dementia Through Diet

A new study suggests people may be able prevent dementia by eating certain foods that contain omega-3 fatty acids.

Fish, chicken, salad dressing and nuts all contain these fatty acids. Eating them may be associated with lower blood levels of a protein related to Alzheimer’s disease and memory problems, according to a news release from the American Academy of Neurology.

The study, supported by the National Institute on Aging, was published in the online issue of Neurology, the medical journal of the American Academy of Neurology.

“While it’s not easy to measure the level of beta-amyloid deposits in the brain in this type of study, it is relatively easy to measure the levels of beta-amyloid in the blood, which, to a certain degree, relates to the level in  the brain, said Dr. Nikolaus Scarmeas, study author from the Columbia University Medical Center in New York, in the news release.

More than 1,200 people participated in the study. They were older than 65 and free of dementia.

Researchers found that the more omega-3 fatty acids a person consumed, the lower their blood beta-amyloid levels.
