Study Finds No Benefit On Cognitive Decline With Omega-3 Supplements

It is a very common practice to have omega-3 supplements to boost brains. But this has been lately proved wrong. A new study conducted by the National Institutes of Health has found it is not effective on cognitive decline.

The study was conducted on about 4,000 patients of average age 72 years and more than half of the participants were female.

All the participants were analyzed between 2006 and 2012 and under a part of Age-Related Eye Disease Study 2. Researchers also tested them for cognitive decline in every two years during the six years study duration and it was designed to measure brain processing speed, attention and memory, and immediate and delayed recall.

All the subjects were segregated in four groups and they were given omega-3, lutein, zeaxanthin and placebo in an unique method such as one group was given only omega-3, the next was given lutein as well as zeaxanthin, the third was given omega-3, lutein and zeaxanthin too, and the fourth group was given only placebo.

Lutein and zeaxanthin are found in green vegetables.

Details of the study are published in the American Medical Association journal.

National Institute on Aging researcher Dr. Lenore Launer said more research is required to know whether dietary patterns can make a difference.
