Omega-3 supplements to keep the brain young still uncertain, study shows.
Fish oil contained omega-3 fatty acids known to reduce inflammation in the body, and have other health benefits taken from he tissues of oily fish. It was thought to be beneficial in treating hypertriglyceridemia, and possibly beneficial in preventing heart disease. Peru is the main fish oil producer with total of about one-fourth of production.
Numerous studies on health benefits from fish oil and omega-3 fatty acids, in a wide variety of other conditions. This includes clinical depression, anxiety, cancer, and macular degeneration, however benefits are still unclear. In a 2012 meta-analysis,found Omega-3 Fatty Acid supplementation did not reduce the chance of death, cardiac death, heart attack and even stroke.
“Our analysis suggests that there is currently no evidence that omega-3 fatty acid supplements provide a benefit for memory or concentration in later life,” said co-author of the study, meta-analysis published in June 2012 found no significant protective effect for cognitive decline for those aged 60 and over.
Previous study shows omega-3 supplements did not improve the brain health of older patients with pre-existing heart disease, 2011. In statement of study author Emily Chew, deputy clinical director at the National Eye Institute and part of US National Institutes of Health, “Contrary to popular belief, we didn’t see any benefit of omega-3 supplements for stopping cognitive decline.” A much better bet for all-around brain and heart health is eating foods naturally high in omega-3 fatty acids like salmon, flaxseed and walnuts.
“ Similarly, this clinical trial suggests there is no benefit to taking omega-3 in later life when it comes to memory and thinking skills, although this study didn’t go on to look at a dementia diagnosis. As volunteers in this study had age-related macular degeneration and were being treated for this condition, it is difficult to know how these results apply to the wider population,” Dr Simon Ridley, Head of Research at Alzheimer’s Research UK said.
Research suggest taking fish oil supplements are not enough to keep the brain young. Former head of the American Heart Association Robert Eckel stated, “It would be a good time for that to be updated.”, “Almost all studies of fish oil supplements show no benefit. I really feel this remains unproven. IMAGE/Danny E Hooks/shutterstock
