One of the standout features of fish is its rich omega-3 fatty acid content, particularly prevalent in fatty fish like salmon and mackerel. Omega-3s offer many health benefits, from supporting brain function to reducing inflammation. According to the National Institutes of Health, some fish are richer sources of omega-3s than others, such as salmon, mackerel, tuna, herring, and sardines.
“Omega-3 fatty acids are an essential nutrient the body cannot make on its own but have powerful benefits in fighting chronic inflammation and maintaining brain and heart health,” Moody explains. “Recent research even suggests it has benefits for athletic performance. Fish is the most potent dietary source of omega-3 fatty acids, and all you need to do is eat one serving of fatty fish one to two times a week to meet recommendations.”
