Researchers have proven that the higher the dietary intake of omega-3 essential fatty acids (such as DHA), the lower the levels of amyloid beta-protein in the blood. Lower levels of amyloid beta-protein in your blood predict that less of this protein will wind up in Alzheimer’s brain tangles, thus helping reduce the risk for cognitive decline. The researchers found that the more these oils were consumed the lower the levels went.
“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 study author Nikolaos Scarmeas, MD, MS, Columbia University Medical Center, New York and American Academy of Neurology member.
Consuming 1 gram of omega-3 per day (equal to approximately 1/2 fillet of salmon per week) more than the average omega-3 consumed by people in the study is associated with 20 to 30 percent lower blood beta-amyloid levels. The researchers found that the more these oils were consumed, including from supplements, the lower the levels went.
The study correlated the blood levels of amyloid beta-protein to the cognitive functions of the study group and found that the lower levels correlated to reduced risk of cognitive decline and Alzheimer’s disease.
Of course, the most potent omega-3 demonstrating brain protection is DHA, which has many benefits for brain health, metabolic health, and cardiovascular well-being. Higher level of intake is clearly advantageous for many health issues facing Americans.
