Fish Consumption and AF: No Increased Risk of Omega-3s

Regular consumption of fish and other foods rich in omega-3 fatty acids does not increase the risk of developing atrial fibrillation (AF), according to a meta-analysis of population-based studies. The study suggests that concerns about high-dose omega-3 fatty acid supplements and their association with AF risk may not apply to lower-dose habitual dietary intake. The findings support current dietary guidelines recommending fish and omega-3 fatty acid consumption for cardiovascular health. However, caution should be exercised when prescribing high-dose omega-3 fatty acid therapies, and further research is needed to understand the effects of omega-3 fatty acids on atrial arrhythmias in individuals with existing cardiovascular disease.
