AHA Recommends Two Seafood Meals a Week to Lower CVD Risk

May 18, 2018

Consuming 1 to 2 seafood meals weekly is associated with a reduced risk of cardiovascular disease (CVD), according to a new science advisory from the American Heart Association.

This association is especially potent when seafood replaces intake of less healthy foods, the authors of the statement wrote.

The advisory was issued in light of continually emerging evidence from observational and experimental studies and from randomized controlled trials that further validate the heart-healthy effects of long-chain n-3 polyunsaturated fatty acids found in seafood—such as anchovies, salmon, and Atlantic and Pacific mackerel.

In their advisory, the AHA makes the following statements:

  • Eating 1 to 2 servings of seafood weekly is associated with decreased rates of sudden cardiac death.
  • In general, consuming 1 to 4 servings of seafood per month associated with a lower risk of coronary heart disease.
  • Fish consumption may be associated with a lower risk of ischemic stroke, but not hemorrhagic stroke.
  • Various trials have demonstrated that fish oil supplements are associated with blood pressure reduction. However, few trials have assessed the specific effects of seafood on blood pressure.
  • Some, but not all, studies have found that seafood intake is associated with a decreased risk of congestive heart failure.
