Omega-3 supplements harm brain, not help: Chinese study
The study was based on an analysis of more than 800 elderly people in North America. About half of them had a gene called APOEε4, which increases the risk of dementia.
The data showed that people who took omega-3 supplements had a significantly faster decline in cognitive ability than those who did not.
The findings of the study were published online in April and will be published in the June issue of The Journal of Prevention of Alzheimer’s Disease.
“These findings challenge the prevailing view that omega-3 is always beneficial and emphasize the need to carefully reevaluate its widespread use for cognitive protection,” the researchers wrote.
