Omega-3 rich butter not heart tonic
Adding margarine enriched with omega-3 oils to the diet of patients with a history of heart attacks does not protect them against a second attack, a new study says.
Previous studies have considered omega-3 fatty acids as heart tonic. Many physicians therefore recommend their heart patients take their regular cardiac pills and follow a diet rich in omega-3 fatty acids in order to reduce the blood levels of triglyceride and subsequently the risk of developing cardiovascular events.
According to the study published in the New England Journal of Medicine, taking low doses of omega-3 fatty acids in margarine does not lower the risk of serious heart attacks and other major cardiovascular events in patients with an underlying heart condition in the long run.
Women and diabetic patients, however, benefited from alpha-linolenic acid (ALA) margarine as the consumption of the omega 3-fatty acid fortified butter was associated with a non-significant reduction in the risk of experiencing repeated heart attacks and other cardiovascular events in them.
Fish like salmon, herring and sardine are a common source of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), while ALA is found in vegetables including soybeans, flax seeds and walnuts.
