<human>:  What is a heart healthy diet?
<bot>: A heart healthy diet is one that is low in saturated and trans fats, high in fiber and low in sodium. It should also include plenty of fruits, vegetables, whole grains, and lean proteins. Eating foods that are high in omega-3 fatty acids, such as salmon, mackerel, sardines, tuna, and herring can provide additional health benefits as well.
