Heart disease is (still) the number-one killer of women in the United States, so it's important to keep your ticker in shape.
The Best Source of Omega-3 Fatty Acids is Salmon
Both salmon and walnuts are great ways to boost your omega-3 intake, which can benefit heart health. But salmon is better for you: Walnuts pack loads of ALA (the plant-based source of omega-3s), which your body must convert into EPA and DHA (forms of omega-3s your body can use), and the conversion process is inefficient. On the other hand, fish-based sources, such as salmon, already contain DHA and EPA—which is why many experts tout fatty fish as the better option.
