New research is casting doubt on whether foods rich in Omega-3 fatty acids, such as salmon and nuts, can preserve your memory as you age. Researchers from Iowa followed more than two thousand woman ages sixty five and older for an average of six years. They found no relationship between the level of Omega-3 fatty acids in the women's blood and their cognitive ability as they got older. But, experts say the study is limited because it only measures Omega-3 levels in the bloodstream. The researchers themselves say people shouldn't change their diets because of their study. They say fish and nuts are still good for you. Experts say fish and nuts are a good alternative to red meat and full-fat dairy products which are high in saturated fats.
