Â Beginning with 1970 studies showing that Eskimos who ate a lot of fish had low cardiac disease risk, omega-3s in fish oil have been recommended for heart health.
Â New research shows omega-3s to be beneficial in many more ways. Unfortunately, only a quarter of the U.S. population consumes any omega-3 on any given day. Benefits include:
Â Heart: In addition to already-known heart benefits, a study reported by Tufts University links fish consumption and omega-3s to improved electrical function in heart cells. They protect against abnormal heart rhythms.
Â Brain: The DHA in fish oil is the most prominent fatty acid in the brain, especially in the cerebral cortex, which is responsible for memory, language, and thinking.
Â Dementia, Alzheimer’s disease: The USDA Human Nutrition Research Center reports their study subjects with the highest DHA levels reduced their risk of dementia by 47 percent and of Alzheimer’s by 39 percent.
Â Eyes: According to the Archives of Ophthalmology, dietary omega-3 intake is associated with a 39 percent reduction in age-related macular degeneration. Those who take fish oil supplements for dry eye may be able to cease other medications.
Â Joints: It has been known for some time that omega-3s can reduce joint tendernessÂ and the need for corticosteroids in people with rheumatoid arthritis.
Â A daily fish oil supplement could be helpful for the heart, brain, joints, and eyes.
