Throughout history, it has been the center of emotion, the spirit, and the soul. In modern-day medicine, the heart is just as important. Think of the heart as the human engine. Its chambers pump the blood that delivers the oxygen and nutrients to every corner and crevice of our bodies and returns all of the waste and carbon dioxide, fueling our ability to move forward with daily life. For something that we know is so important to us, we treat the heart pretty poorly. The good news is that the choices we make each day can have a marked effect on heart health.
