Research Question:
Lowers eating fish or long chain omega-3 fatty acids the chances of getting Alzheimer's disease?
Study Design:
This overview article contained prospective cohort studies.
There was a low heterogeneity between the studies and within the subgroups.
Results and conclusions:
The researchers found that both eating lots of long chain omega-3 fatty acids as fish the chance of getting dementia not significantly reduced [RR respectively = 0.97, 95% CI = 0.85-1.10 and RR = 0.84, 95% CI = 0.71-1.01].
The researchers found that eating a lot of long chain omega-3 fatty acids, the chances of getting Alzheimer's disease are not significantly by 11% [RR = 0.89, 95% CI = 0.74-1.08] reduced.
Not significant is, there cannot be said with 95% reliability that eating lots of long chain omega-3 fatty acids, the chances of getting Alzheimer's disease reduced.
The researchers found that eating a lot of fish, the chances of getting Alzheimer's disease significantly with 36% [RR = 0.64, 95% CI = 0.44-0.92] reduced.
The researchers found that eating 100 grams of fish per week, the chances of getting Alzheimer's disease significantly with 11% [RR = 0.89, 95% CI = 0.79-0.99] reduced.
The researchers concluded that eating a lot of fish (at least 100 grams per week) the chances of getting Alzheimer's disease (and not dementia) reduced.
