Dietitians at Intermountain Health say eating fish once or twice a week can lower your risk of heart attack, stroke and coronary heart disease. These benefits are tied to omega-3 fatty acids found in fish. Omega-3 regulates body functions to improve heart health, brain health, and reduce inflammation.

“Omega-3 is an essential fatty acid, which means the body cannot produce it on its own,” said Carly Alba, registered dietitian nutritionist at Intermountain Medical Center. “We have to get omega-3 through diet, and the best way is by eating fish at least once a week to reap the benefits.”

Studies consistently show that Americans don’t consume enough omega-3, which can lead to flaky and itchy skin, slow wound healing, diarrhea, and hair loss.

There are three types of omega-3s. Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are the most robust, and are found in seafood. The third is alpha-linolenic acid (ALA), found in plant foods such as flaxseeds, chia seeds, and walnuts.

Adults – especially those with evidence of cardiovascular disease – should consume one gram of omega-3 daily, Alba said. The best food source of omega-3 is fatty fish, with salmon having the most.

Alba shares this list of fish and their omega-3 content (3-ounce serving):

Atlantic Salmon – 1.8 grams
Anchovies – 1.7 grams
Sardines – 1.4 grams
Rainbow trout – 1 gram
Tuna, canned – 0.7 grams
Halibut – 0.4 grams
Catfish – 0.2 grams

Not into fish? A fish oil supplement may be appropriate, Alba said. But be cautious: People with bleeding disorders or who take anticoagulant medications should limit their use.

“Always follow the recommendations of your primary care provider when it comes to medications and supplements,” Alba said.

So at your next backyard barbecue, consider mixing in a halibut or salmon steak with the typical burgers and dogs. Your heart and brain will thank you. More nutrition information can be found at intermountainhealthcare.org.
