Omega-3 fatty acids commonly found in - flaxseed oil, walnuts, salmon, soybeans, and spinach - have shown anti-amyloid and anti-inflammatory actions in the brains of animals. 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 and make skin healthy, among many other benefits.
Consuming food items rich in omega-3 may raise blood flow to areas in the brain associated with memory and learning, thus reducing the risk of Alzheimer's disease. 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.(Also Read: 8 Incredible Sources of Omega 3 Foods: More Than Just Fish)
The study was published in the Journal of Alzheimer's Disease and demonstrated the value of nutritional intervention for brain health by using the latest brain imaging technique known as Single photon emission computed tomography, or SPECT. The technique is known to measure blood perfusion in the brain. The images acquired from 166 participants - who were on a high omega diet - performing various cognitive tasks showed higher blood flow in specific brain regions.Inputs from IANS
