Monday Sept 7, 2015 (foodconsumer.org) -- A new meta-analysis published in Neuroscience & Bio behavioral Reviews suggests that intake of fish, but not long chain omega-3 fatty acids found in cold water fatty fish, may reduce the risk of Alzheimer's disease. But fish may not affect the risk of other forms of dementia.
Meta-analyses revealed that higher intake of fish was associated with a 36% reduced risk for Alzheimer's disease, the major form of dementia, but not significantly associated with risk of other forms of dementia.
Specifically, intake of an additional 100 grams of fish per week was correlated with an 11% lower risk for Alzheimer’s disease.
The new study did find an association between higher intake of long chain omega-3 fatty acid and 11% lower risk of Alzheimer's disease, but the association was considered statistically insignificant.
The study concluded that intake of fish, but not omega-3 fatty acids was significantly associated with the reduced risk of Alzheimer's disease. Intake of neither fish nor omega-3 fatty acids was associated with reduced risk of dementia. (David Liu)
