The CNN “The Chart” blog reports, “People who eat a diet rich in omega-3 fatty acids may significantly lower their risk of developing memory problems and Alzheimer’s disease,” according to a study published in the journal Neurology.
“The finding stems from work conducted among roughly 1,200 dementia-free patients over the age of 65,” HealthDay reports. “All underwent blood tests to assess levels of a key Alzheimer’s-associated protein after providing the study authors with a dietary breakdown dating back more than a year.”
Investigators “showed that people whose diets contained the most omega-3 had the lowest blood levels of a protein known as beta-amyloid,” WebMD reports. “Blood tests conducted an average of a year after the dietary survey revealed that people who ate the most omega-3 fatty acids had lower beta-amyloid levels. The association was not seen with other nutrients.”
MedPage Today reports that the study authors did acknowledge, however, that “plasma beta-amyloid proteins do not necessarily reflect amyloid protein levels in the brain.”
