A new scientific study points out that omega-3 supplements do not boost brain activity, and that this is, in fact, a myth. It seems research teams did not observe the potential beneficial effects omega-3 supplements would have in stopping cognitive decline. An earlier study had been conducted in August, which also shattered the Omega-3 myth.
Health experts conducted a clinical trial which showed that a diet which contained fish oil as well would not prove beneficial, in the end. Fish oil doesn’t seem to protect the brain, nor does it improve cognitive abilities.
Omega-3 supplements are based on high concentrations of fish oil, but these capsules are different from the nutrients found in nature, in fish and marine algae.
The National Institutes of Health monitored 4,000 patients and found out that the fatty acids wouldn’t alleviate cognitive decline. The researchers said that the supplements didn’t improve old people’s health.
Researchers monitored participants that were, on average, 72 years old, and 58 percent were female. They grouped the patients, and asked them to add to their diet several nutritional supplements, including: Placebo, Omega-3, lutein and zeaxanthin (found in green leafy vegetables), and, lastly, Omega-3 and lutein/zeaxanthin.
The scientific team initially measured participants’ cognitive functions, and after two and four years, respectively, the tests were repeated. The tests contained eight parts. The parts would put to the test participants’ memory, attention and processing speed. But they finally discovered that the cognitive decline wasn’t ameliorated, therefore those supplements had no role to play in all this. They had also focused on eye examinations.
So it seems that in patients suffering from Alzheimer’s disease, DHA had no significant effect, despite it did decrease the number of beta-amyloid plaques in mice. DHA means docosahexaenoic acid , found in Omega-3.
The clinical director at the National Eye Institute, part of the National Institutes of Health, said that:
“It is possible that eating foods rather than taking any specific single supplement may have an effect.”
However, researchers plan to take a closer look at the issue, as they want to ascertain whether fish oils plays a role in alleviating early Alzheimer’s symptoms.
