Think ‘omega-3’ and you might think of salmon, but a large research review has found that the major plant-based version of the nutrient, known as alpha-linolenic acid (ALA), can benefit heart health and reduce the risk of heart disease for those who don’t eat seafood. Intake of ALA from plant-food sources like walnuts, chia, and flaxseeds, was linked with a 20% reduced risk of fatal heart disease. Researchers also found that people who already have high intake of omega-3 from seafood still get extra benefits from eating these plant-based sources.
