Omega-3 fatty acids make it heart-healthy
The benefits of eating lots of fish, which is rich in omega-3 fatty acids and a heart-healthy food, seem to outweigh any risks that come from species with high levels of the neurotoxin mercury, a new study suggests. Researchers looked at over 900 Swedish men and women, asking them questions about the amount of fish in their diet and analyzing their red blood cells for levels of mercury and selenium, another element tied to heart health, Reuters reports. Even though their mercury leels were low by Scandinavian standards, people whose red blood cells showed high levels of mercury didn’t have a higher risk of cardiac problems than those with less of it, they found. The American Heart Association recommends at least two servigs of fish a week.
