Omega-3's May Keep Your Mind Sharp As You Age
A study published in the November 2010 issue of Alzheimer's & Dementia: The Journal of the Alzheimer's Association found that the omega-3 fatty acid DHA may help keep your mind sharp as you age.
The study was titled the “Memory Improvement with Docosahexaenoic Acid Study” and included 468 participants over the age of 50 with mild age-related cognitive decline. The participants were randomly assigned to receive daily supplements containing 900 mg of DHA or a placebo for 24 weeks.
At the end of the 24 week supplementation period the researchers found that participants given the DHA supplement had significant improvements in memory and learning.
The researchers noted that this study provides valuable information on the role Omega-3's, and specifically DHA, play in cognitive function.
There has been an increasing amount of science showing that having low omega-3 levels increases the risk of Alzheimer's and this study highlights the necessity of taking a proactive approach and supplementing with omega-3's before cognitive issues arise.
Beyond boosting cognitive function, there are numerous other benefits associated with omega-3 fatty acids. Previous studies have found that these essential fatty acids may help improve heart health, reduce the risk of age-related vision loss and even help improve your mood.
Taking a high quality supplement is a good way to increase omega-3 intake, just be sure that the supplement you choose is certified for purity and high in DHA and EPA, the two most important omega-3 fatty acids. Oily fish like salmon, mackerel and tuna are also high in omega-3's.
