Researchers at the University of Utah recently conducted an in depth study on omega-3′s and found new evidence supporting the eye health benefits of these essential fatty acids. Their findings were published in the August 2010 issue of the Journal of Lipid Research.
For the study researchers used donor eyes and categorized them into four groups: young, middle-aged, old, and eyes with aged related macular degeneration (AMD.)
AMD is the leading cause of severe vision loss and blindness in the Western world. It is a progressive disease that attacks the macula of the eye and affects over 15 million Americans. It causes central vision loss and leaves only peripheral vision.
The researchers conducted extensive tests on the eyes and found that eyes with AMD had significantly lower levels of DHA and EPA, two of the most important omega-3 fatty acids.
These findings support a number of previous studies including one study published in the July 2010 issue of the journal Ophthalmology which found that just one serving of fatty fish per day may decrease the risk of developing AMD.
The eye health benefits of omega-3′s are likely due to the anti-inflammatory and antioxidant properties of these essential fatty acids.
Some fish that are high in omega-3 fatty acids include salmon, mackerel and tuna. You can also boost your omega-3 intake by taking a high quality supplement but be sure to look for supplements high in the most important omega-3 fatty acids EPA/DHA and certified for purity.
