Arthur Agatston, the Miami cardiologist who created the popular low-carb South Beach Diet, is no stranger to chocolate.

"I've always been a chocoholic," he said, admitting to a special craving for chocolate-covered macadamia nuts that "call to him" from airport kiosks whenever he's traveling.

So when it comes to Valentine's Day, Agatston is especially eager to help the diet-conscious enjoy treats in the healthiest way possible. That could mean savoring a bit of dark chocolate this Valentine's Day.

Of course, "you can run into trouble with too much chocolate," he said. But he noted there's been a steady stream of good data on the health effects of dark -- but not milk -- chocolate. Some research even suggests that a moderate amount of the dark delight could be good for your heart.
