FINDS: Eating food high in
fish oils such as omega-3 doesn’t reduce the risk of heart disease,
raising questions about national guidelines promoting the fats as
beneficial for cardiovascular health, researchers found. The
analysis of 72 previous studies showed insufficient support for
nutritional recommendations by groups such as the American Heart
Association that advocate high consumption of polyunsaturated fats
like omega-3 and omega-6, which is found in corn and sunflower
oils, as well as some nuts and seeds. Thee findings released
yesterday in the Annals of Internal Medicine are the latest to show
that supplements and vitamins don’t work as well as touted to help
patients prevent diseases. While past studies showed fish oil can
lower unhealthy blood fats, blood pressure and reduce the risk of a
second heart attack, research in recent years contradicted those
findings, suggesting it has limited heart benefits.
