Nobody knows why, but it looks like chocolate is good for your heart. And not just when it comes from your sweetheart on Valentine's Day! It's not a definitive conclusion, but there appears to be a link between consuming chocolate and a reduced risk of heart disease. Scientists from the University of Cambridge have studied seven studies involving 100,000 people. Five of those studies demonstrated a link between eating chocolate and heart health. Two did not. researchers want to study the link further to make sure it's the chocolate that causes better heart health or if it's actually due to something else. Where do I sign up for that research project?
