- Description: A meta-analysis tied eating fish to 16% lower dementia risk and 36% lower Alzheimer's risk, with each extra 100 grams of fish a week linked to an 11% reduction. Intake of long-chain omega-3 fatty acids themselves showed no significant association with either.

A review published in Neuroscience & Bio behavioral Reviews suggests eating fish often may reduce the risk of dementia like Alzheimer's disease.

The review was intended to examine the association of omega-3 fatty acid intake with incidence of dementia and Alzheimer's disease as previous studies are inconsistent when it comes to how dietary omega-3 fatty acids could affect the risk of dementia.

The review found no association between intake of long-chain omega-3 fatty acids, which are found high in cold water oily fish such as salmon, and risk for dementia while consumption of fish was linked to 16% reduced risk for dementia.

Similarly, intake of long chain omega-3 fatty acids was not found associated with significantly reduced risk of Alzheimer's disease while eating fish was correlated with 36% reduced risk of Alzheimer's disease.

Specifically, intake of each additional 100 grams of fish per week was associated with 11% reduced risk of Alzheimer's disease.

The review suggests that eating fish, but not taking fish oil or long chain omega 3 fatty acids supplements lowers risk of dementia or Alzheimer's disease.
