How Fish Oils Help Stave Off Dementia

[Spoon]

Fish oil may protect against Alzheimers by combating harmful brain plaques which lead to the disease.

Research shows that an omega 3 fatty acid found in fish oil boosts production of a beneficial protein that can stop the plaques developing.

Although previous studies have shown that fish oils taken by pill or in the diet may delay or even prevent Alzheimers, it is the first time that scientists have identified why they have a beneficial effect.

The study, which was published in the Journal of Neuroscience, revealed that the omega 3 fatty acid DHA (docosahexaenoic acid) increases the production of LR11, a protein found at reduced levels in Alzheimers patients.

LR11 has already been shown to destroy the brain plaques which kill brain cells.

Salmon, mackerel and trout contain the highest levels of fatty acids, he added, but it was not yet certain how much needed to be eaten to stave off dementia.

Alzheimers is the most common cause of dementia. And hundreds of new cases are diagnosed every day as more people live longer.
