This ocean-going fish is a top choice because it’s rich in omega-3 fatty acids. Omega-3s have an anti-clotting effect, so they keep your blood flowing. They also help lower your triglycerides (a type of fat that can lead to heart disease).

Aim for at least two servings of oily fish each week, says the American Heart Association. A serving is 3.5 ounces.  That’s a little bit bigger than a computer mouse.

Other options: Tuna, trout, sardines, and mackerel.
