22 May 2017 --- Research involving neuroimaging has shown that people with higher omega 3 levels have increased blood flow in regions of the brain associated with memory and learning, according to a report in the Journal of Alzheimer’s Disease. With the incidence of Alzheimer’s disease (AD) expected to triple in the coming decades, interest in dietary approaches for the prevention of cognitive decline has increased. In particular, the omega 3 fatty acids have shown anti-amyloid, anti-tau and anti-inflammatory actions in the brains of animals.
