Consume foods rich in omega-3 to reduce Alzheimer's risk!

New Delhi: Omega-3 fatty acids are and should be an important part of everyone's daily diet, since they are essential to overall health.

Health experts have emphasised its importance from time to time and decades of research have been devoted to discovering the many health benefits of omega-3.

A source of both plant and animals, like krill oil, fish oil, flaxseed, chia seeds, hemp, etc, foods rich in omega-3 have the ability to fight depression and anxiety, improve eye health, promote brain health, reduce risk of heart disease, fight inflammation, fight auto-immune diseases, prevent cancer, reduce asthma in children, improve bone and joint health, improve sleep, make your skin healthy, among many other benefits.

Making an important addition to the list of its health benefits, a study has showed that eating foods which are a good source of omega-3 fatty acids, may raise blood flow to areas in the brain associated with memory and learning, thus reducing the risk of Alzheimer's disease.

Alzheimer's is a progressive disease that destroys memory and other important mental functions.

Omega-3 fatty acids commonly found in – flaxseed oil, walnuts, salmon, soybeans, and spinach – have shown anti-amyloid, anti-tau and anti-inflammatory actions in the brains of animals.

The study showed positive relationships between omega-3 EPA+DHA status, brain perfusion, and cognition.

"This is very important research because it shows a correlation between lower omega-3 fatty acid levels and reduced brain blood flow to regions important for learning, memory, depression and dementia," said lead author Daniel G. Amen, CEO, the Amen Clinics Inc in the US.

Further, the study also demonstrates the value of nutritional intervention for brain health by using the latest brain imaging technique known as Single photon emission computed tomography, or SPECT, which can measure blood perfusion in the brain.

"This study opens the door to the possibility that relatively simple dietary changes could favorably impact cognitive function," added William S. Harris, from the University of South Dakota

In the study, appearing in the Journal of Alzheimer's Disease, the images acquired from participants performing various cognitive tasks will show higher blood flow in specific brain regions.

In the study, the team analysed the brain images acquired from 166 participants with high Omega 3 levels performing various cognitive tasks and found higher blood flow in specific brain regions involved with memory, and neurocognitive testing.

In addition, they also found that omega-3 levels also correlated with various psychological feelings of the participants.
