Researchers say omega-3 may help prevent Alzheimer's disease.


Omega-3 fatty acids are found in fish, nuts, vegetable oils, and leafy vegetables. This type of fat has been recognized as benefiting heart disease, stroke, rheumatoid arthritis, cancer and other conditions reports the Harvard T.H. Chan School of Public Health. Researchers now say omega 3 fatty acids may help prevent Alzheimer's disease.

Omega 3 fatty acids cross the blood brain barrier

There has been a great deal of interest in the potential for omega-3 fatty acids to impact better outcomes in patients with Alzheimer's disease. It has been observed that omega-3 fatty acids can cross the blood brain barrier which enhances its potential to prevent Alzheimer's disease.

The Alzheimer's Society reports fish is often known as "brain food". The evidence is good that eating fish, which has omega-3 in it, is beneficial for your health. Eating fish may decrease the risk of developing dementia, particularly when it is eaten as part of a diet which is healthy.

Omega-3 is vital for our brain throughout life. This is witnessed from the early cognitive development in fetuses to learning and memory as people grow up. It is thought that brain cells which have high levels of omega-3 in their membranes are better at communicating with other cells, which is a significant process for the functioning of the brain.

The Journal of Alzheimer's Disease reports that via neuroimaging it has been observed there is increased blood flow in regions of the brain which are associated with memory and learning in people who have higher levels of omega-3 fatty acids. This offers strong support for the value of nutritional intervention for the health of the brain.

Alzheimer’s disease is a devastating condition is expected to triple in the decades to come. As of this time no cure
has been found for this disease. There has been increasing interest in dietary approaches to help prevent cognitive decline as we age. It is compelling that patients with high omega-3 levels have been found to have increased blood flow in specific parts of the brain.

Positive relationships have been found between omega 3 levels, brain perfusion, and cognition

Researchers found that overall there were positive relationships between omega-3 levels, brain perfusion, and cognition. A correlation has been observed between lower omega-3 fatty acid levels and decreased brain blood flow to regions which are important for memory, learning, depression and dementia.

There has already been a great deal of evidence that levels of omega-3 are associated with better cardiovascular health as noted by co-author William S. Harris, PhD, of the University of South Dakota School of Medicine. Now it is understood that relatively simple changes in the diet could have a favorable impact on cognitive function. It's a good idea to make omega-3 rich fish a regular part of your diet.
