Protecting the heart may not be as easy as eating salmon, nuts and seeds. For years, researchers have said that eating foods high in fish oils, such as omega-3, reduces the risk of heart disease, but now they say that is not the case.
Analysis of seventy-two previous studies shows omega-3 and omega-6 are not as beneficial as first thought. They looked at more six hundred thousand patients from eighteen countries.
The findings released in the Annals of Internal Medicine are the latest to show that supplements and vitamins do not work as well, as originally reported, in people to prevent heart disease.
Another study published in Monday's edition of JAMA Internal Medicine finds daily omega-3 supplements are not associated with a reduced risk of heart attack, stroke or cardiovascular death in older patients with eye disease.
The new findings are raising questions about current national guidelines promoting the fats as beneficial for cardiovascular health. Current heart association guidelines recommend about two servings of fatty fish each week. They also recommend that five to ten percent of total daily calories should come from omega-6 sources.
