German researchers have noted in a study that people who consumed 7.5 grams of dark chocolate daily had a lower risk of having a heart attack or stroke as compared to those who ate the least amount of chocolate, an average of 1.7 grams a day.

Brian Buijsse of the German Institute of Human Nutrition in Nuthetal, who led the study, said people not stuff themselves with chocolates following these findings.

He added, "Small amounts of chocolate may help to prevent heart disease, but only if it replaces other energy-dense food, such as snacks, in order to keep body weight stable."

Researchers added that more research was needed in this field but they think the flavanols in cocoa may be the reason why chocolate is good for heart health and blood pressure. Dark chocolate is better as it will have more cocoa.
