How Much Chocolate Can Support Your Cardiovascular Health? A New Study Investigates

It's widely known that a varied diet of fruits and vegetables offers the most nutritional benefits to the body. But what if chocolate was just as good for you—even supporting your cardiovascular health?

Well, we all know that it's important to care for your heart through employing positive habits like working out and eating a balanced diet. Yet even so, atherosclerotic cardiovascular disease (ASCVD) is a major cause of death in U.S. adults each year.

This study worked specifically with cocoa supplementation and not chocolate bars or general drugstore candy—so no, a big bar of chocolate a day will not necessarily keep the doctor away.

Throughout the study, the 21,442 participants took two capsules of cocoa flavanol each day for nearly two years. On top of this, some participants were assigned to take additional multivitamins or a placebo, and the study reached out for follow-up at the six- and 12-month marks. This process also took into account outside health concerns, lifestyle, and sociodemographic factors so that participants were at similar starting points at the beginning of the study.

Unfortunately for milk chocolate lovers, this highly processed option is not the healthy cocoa the study refers to for heart support. In fact, it would take about 50 servings of milk chocolate to help you reach the flavanol content of the cocoa extract supplements. Needless to say, that's not great for your health when you're considering sugar intake.

One of the primary limitations of this study is the wide range of cardiovascular issues it considers. The authors acknowledge that instead of looking at the broad number of cardiovascular concerns the body could experience, a clearer picture may be painted in narrowing in on heart attack, stroke, and cardiovascular disease.

Additionally, the cocoa extract supplement that was tested included a number of natural bioactive components available in cocoa, and the authors note that it's difficult to separate which may be responsible for the positive impact on the heart outside of flavanols.

As much as we would love chocolate to be the answer to our health problems, the supplementation of cocoa extract showed no significant reduction in the likelihood of experiencing cardiovascular issues. That being said, the study did reveal that it may reduce the severity of heart concerns, lowering the likelihood of death by 27%.
