A new study indicates that Omega-3 fatty acids and mercury, both found in fish, appear to have opposing affects on cardiac health and risk of myocardial infarction.
This study published in the American Journal of Clinical Nutrition, looked at data from more than 1,600 men from Sweden and Finland. Men with high levels of mercury in their body had an increased risk of heart attacks, while those with a high concentration of omega-3s had a lower risk.
