Chocolate for the heart?

A new research study from the U.K. shows that chocolate could cut heart disease and stroke risk by one-third. This was a large scale analysis of other studies with over 100,000 participants who were studied for a minimum of 8 years.

Those who ate the most chocolate had a lower heart disease and stroke risk when compared to those who ate the least amount of chocolate. All types of chocolate and all sources of chocolate were counted, milk chocolate to dark chocolate and from bars, drinks, and cookies.

As fascinating as this study is, it doesn’t necessarily prove without a doubt that chocolate is protective against heart disease and stroke. Other factors were not taken into account, so chocolate eaters may be participating in other heart-healthy activities or eating habits. The positive news is that chocolate isn’t bad for you, especially in moderate amounts (this study confirmed about once or twice per week).

The components in the chocolate that helped improve heart-health were not individually studied. But, previous research has showed beneficial polyphenols in the chocolate. These substances have antioxidant properties (which help prevent free radical damage to cells in the body), lower blood pressure, and prevent inflammation.

Even though this study didn’t distinguish between different types of chocolate, previous research studies show that dark chocolate may be best for heart protection.

Another interesting thing to note is that some previous chocolate studies have been funded by chocolate companies, whereas this study was done by researchers at the University of Cambridge in England. The studies that they reviewed did not have funding from the chocolate industry and included participants from various countries.

One negative aspect of chocolate is that too much can lead to weight gain. Weight gain over time can lead to overweight and obesity, which are known risk factors for heart disease. Overdoing it can cause more harmful effects than good.
