Observational data suggests chocolate may protect cardiovascular system.
A meta-analysis of seven observational studies with 115,000 adult participants compared the lowest level of chocolate consumption with the highest intakes. Those eating the most had nearly a one-third decrease in risk for cardiovascular disease and stroke. The authors caution that most forms of chocolate contain high amounts of fat and sugar, and more esperimental research is necessary to prove causation.
