Consuming foods rich in Omega-3 fatty acids may protect individuals from Alzheimer’s and other forms of dementia according to a new study.
As The Inquisitr has previously reported, the beta-amyloid protein is generally considered the most definite link to the likelihood of a person developing brain diseases such as Alzheimer’s, and Omega-3 consumption may significantly decrease the beta-amyloid level, perhaps by 20 to 30 percent.
The principal author of this Omega-3 study, Dr. Nikolaos Scarmeas of C0lumbia University Medical Center, told Fox News that “More and more intake of Omega-3s was associated with lower and lower levels of beta-amyloid in the blood.”
Scarmeas, however, conceded that “we do not understand very well biologically how levels of beta-amyloid in the blood, brain and spinal fluid are related exactly,” and that not all the research identifies a correlation between beta-amyloid in the blood and the brain. He did add that “his own lab had observed that people with higher blood levels of beta-amyloid were more likely to develop dementia, while people with lower levels tended not to.” Moreover, “Omega-3s may be able to reduce oxidative stress on the brain and the resulting vascular damage, or even have some kind of impact on beta-amyloid in the brain. ”
The study published in the Neurology journal concludes that higher dietary intake of Omega-3 fatty acids is associated with lower beta-amyloid levels “a profile linked with reduced risk of incident [Alzheimer's Disease] and slower cognitive decline in our cohort. ”
Salmon, herring, mackerel, anchovies, and sardines are among the cold water oily fish sources of Omega-3 fatty acids. Many holistic-oriented consumers also take fish oil supplements for both brain and heart health.
