We were accustomed to the idea that a diet which contained Omega-3 fatty acids could work wonders on cognitive decline, especially in people who were old. But according to a new study, that idea is now a thing of the past. Omega-3 diets have absolutely no impact on cognitive decline, thus all the years in which we thought we knew better turned out to be wasted years for people who actually needed help.
Emily Chew, researcher at the National Institutes of Health (NIH), declared that, after the study, neither she, not her colleagues have seen no benefit given by Omega-3 to those who needed to fight back brain issues. The study was conducted over 6 years, from 2006 to 2012, and kept a close eye on approximately 4,000 people.
The study was part of the Age0Related Eye Disease Study 2 and the average age of its participants revolved around 72, with approximately 60% of them being females.
All participants underwent cognitive tests once every two years and they had the aim of measuring different cognitive processes. The tests had eight parts and would verify processing speed, memory, attention and delayed recall. The tests were not difficult, quite easy to handle by anybody.
The researchers then proceeded to distribute participants into four equal groups. The first group received Omega-3, the second group received lutein and zeaxanthin, the third received Omega-3, lutein and zeaxanthin, while the fourth group received nothing more than a placebo.
After having conducted the tests, specialists observed that none of these treatments had any impact on cognitive decline, thus rendering them inefficient.
Elizabeth Chew proceeded to declare that “supplements just don’t cut it” and if people are taking them with the hope of impeding negative cognitive functions, they might be disappointed, especially when it comes to older age groups.
Chow suggests that, in order to keep a healthy-brain health, people should eat foods which are naturally high in Omega-3 acids. Some of these foods are walnuts, salmon or flaxseed. Omega-3 supplements are some of the most well-known and used dietary supplements in America, and Chow mentions that they are good for an earlier age.
She admitted that “we don’t know whether these supplements might be beneficial at an earlier age”, mostly because, at the age of 72, there is not much you can do to stop any health issue that is affecting you.
Further investigation is required to see whether Omega-3 is actually beneficial for people of younger age.
