CAT | Fish Oils
Clinical research has shown us that fish-derived Omega-3 fats such as EPA and DHA provide numerous benefits for the human body.‡ In addition to playing an important role in healthy cardiovascular function, Omega-3s support brain health, promote healthy joints, and have even been shown to support optimal digestion.‡ But did you know they also provide key benefits for your eyes?‡
Our bodies undergo many changes as we age, including changes in vision and eye health. However, a new study out of Harvard Medical School shows Omega-3 fatty acids from fish may help protect our eyes by supporting the tiny blood vessels in the retina.‡ This is important because damage to these vessels can affect healthy eyesight.
Researchers found that a diet rich in Omega-3s, such as those found in mackerel, trout, herring, sardines, tuna and salmon, helped protect the blood vessels from damage and supported eye health in elderly adults.‡ In the findings, published in the journal Proceedings of the National Academy of Sciences, Professor Kip Connor, PhD expressed his optimism about the results, saying, “It is our hope that future studies will allow us to develop specific therapeutics that harness this knowledge, resulting in greater visual outcome and quality of life.”
Dr. Connor recommends including plenty of oily fish in the diet or taking a daily Omega-3 fish oil supplement for eye health as well as the overall benefits.‡ Click here to learn more about the benefits of Omega-3s and what to look for in an effective fish oil supplement.
Decades of clinical research have provided many reasons to add more fish-derived Omega-3 fatty acids to our diets—from better digestion and elimination to improved heart, joint and immune health—but are Americans consuming enough Omega-3s to reap the benefits? New research says no.
Results of a new study published last month in Nutrition Journal show a significant number of U.S. adults (age 19 and over) are falling short of the daily recommendations for Omega-3 consumption laid out in the Dietary Guidelines for Americans (DGA) issued by the Department of Agriculture and the Department of Health and Human Services—and that consuming more Omega-3s from food sources as well as fish oil supplements may be necessary to help reduce the risk of heart disease* and benefit overall public health.
Using data compiled from the National Health and Nutrition Examination Survey (NHANES) for a period of approximately five years, researchers analyzed how much fish U.S. adults were consuming and whether they were significant sources of fish-derived Omega-3s. As it turns out, although older adults and males typically consume more Omega-3s than younger adults and females, most are not meeting the daily recommendations for Omega-3 fatty acid intake—about 250 mg, according to the 2010 DGA (the next edition will be released in 2015).
Because there is extensive evidence that fish-derived Omega-3 EPA and DHA are good for the heart, the American Heart Association recommends consuming the equivalent of about 500 mg per day of EPA and DHA if you are healthy and want to maintain heart health. For those with documented coronary heart disease, they recommend 1 gram (1,000 mg) per day, and those with high triglycerides should aim for 2 to 4 grams (2,000 to 4,000 mg) per day. If oily fish is lacking from your diet, consider a high-concentration, purity-guaranteed fish oil supplement, and be sure to look at the label to see how much EPA and DHA you are getting.
*Supportive but not conclusive research shows that consumption of EPA and DHA Omega-3 fatty acids may reduce the risk of coronary heart disease.
