Does Eating Fish Prevent Alzheimer’s?

Alzheimer’s is a horrible disease that causes people to lose their memory. Most of the time it affects the elderly however, some people can develop early onsets as depicted in the movie Still Alice (it can affect people in their 50’s). Recently, a study published in JAMA, the Journal of American Medicine Association, concluded seafood is linked to a reduced risk of dementia-associated brain changes in people who carry the ApoE4 gene variation, which increases the risk for Alzheimer’s disease.


First, the researchers controlled the experiment for age, sex, education and other facts and still found that compared with those who ate less seafood, ApoE4 carriers who had one seafood meal or more a week had lower densities of the amyloid plaques and neurofibrillary tangles typical of Alzheimer’s disease. In English, that means that overall they had a 47 percent lower likelihood of developing Alzheimer’s post-mortem.


According to Professor Martha Morris at Rush University, mercury from fish doesn’t have a big risk for older people, however pregnant women need to watch their mercury intake. Too much mercury can cause cognitive problems in babies.


In summary, it is definitely beneficial to have some seafood although over-eating it won’t lower your chances even more for Alzheimer’s. Next time you go to a restaurant, try ordering your favorite seafood dish just incase!
