Omega-3 Fatty-Acids Could Improve Vision

Numerous studies have linked omega-3 essential fatty acid intake with a reduced risk of age-related macular degeneration, many of which we've previously discussed. A new study, published in the April 2012 issue of Neurobiology of Aging suggests that omega-3 essential fatty acids may also improve vision in mature adults.

The Swinburne University, Australia, based researchers conducted a triple-blind placebo-controlled randomized repeated-measures trial with 74 adults between the ages of 45 and 77. They received either 1000 mg of tuna oil which contained 252 mg of DHA, 60 mg EPA and 10 mg vitamin E or a soybean oil placebo daily for 90 days.

Visual acuity and plasma levels of DHA were determined at the beginning of the study and after 90 days of supplementation. The participants who received the tuna oil supplement were found to have significantly raised plasma levels of DHA as well as significant improvement in eyesight. For participants with corrected vision, those who received the tuna oil had markedly better visual acuity compared to those in the placebo group.

In addition to eye health, omega-3s have been linked to an impressive number of health benefits, including improved heart health, alleviating arthritis pain, improvements in mood, improved joint mobility, helping with age-related macular degeneration, brain health and aiding your immune system.

Because omega-3 fatty-acids are not created by the human body, it is essential that you make sure they're part of your daily diet. Oily, dark fish such as tuna and salmon are high in DHA and EPA omega-3s, while ALA omega-3 fatty-acids are plant derived and can be found in flaxseed oil, vegetable oil, and walnuts.

If you're worried about the high mercury content that can be found in fish, or you feel like you're just not getting enough of these foods in your diet, consider a high quality supplement that has been tested for purity and potency.
