Heart disease is America’s number one killer, accounting for about one in four deaths in the U.S. It’s no wonder, then, that we spend billions in research to combat it. The problem: Such spending results in an ever-shifting flurry of studies that can be more confusing than illuminating. Take saturated fat. We’ve been told for decades that it’s bad – yet the cover of Time recently directed us to “Eat Butter.” We’ve received similarly mixed messages about the benefits of cardio training, supplements, and even the right blood pressure numbers to have. How to navigate these murky scientific waters? We did a deep dive and came up with simple steps to safeguard your heart. Think of it as cardiac wisdom for the ages – regardless of what the next blaring headline has to say.
