Consuming 1 to 2 servings of seafood per week reduces the risk of sudden cardiac death, coronary heart disease, ischemic stroke, and congestive heart failure, particularly when seafood replaces less healthy foods.
Eat 1 to 2 servings of fish per week, focusing on oily fish like salmon, sardines, or canned tuna. Avoid frying the fish. This simple change can significantly lower your risk of heart attack, stroke, and sudden cardiac death, especially if you swap out less healthy proteins like processed meats.
We conclude that 1 to 2 seafood meals per week be included to reduce the risk of congestive heart failure, coronary heart disease, ischemic stroke, and sudden cardiac death, especially when seafood replaces the intake of less healthy foods.
Why this rating
