Can One Serving of Fatty Fish Help you Avoid Age Related Vision Loss?
A study published recently in the July 2010 issue of the journal Ophthalmology found that older adults that consume fatty fish at least once a week have a significant reduction in the risk of developing age 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.
For the study, researchers from Johns Hopkins University recruited 2,520 adults between 65 and 84 years of age.
All of the participants underwent a complete eye examination and filled out dietary questionnaires. The researchers found that 15% of the participants had early or intermediate stage AMD and 3% had advanced AMD.
Initially, the researchers found no association between overall fish intake and reductions in AMD risk. However, when they focused solely on fatty fish intake they found a significant correlation.
Specifically, they found a 60% reduction in AMD risk among participants that consumed one or more servings of fatty fish per week compared to those that ate less than one serving.
Salmon, mackerel and tuna are all high in these essential fatty acids. They can also be found in supplement form but be sure to look for supplements high in the most important omega-3 fatty acids EPA/DHA and certified for purity.
