Chocolate may be beneficial for reducing stroke risk in men. Flavonoids found in chocolate may decrease blood concentrations of bad cholesterol and reduce blood pressure. Flavonoids, a group of polyphenolic compounds known to have beneficial biochemical and antioxidant effects, appear to protect against cardiovascular disease through antioxidant, anti-clotting and anti-inflammatory properties. Men who ate the largest amounts of chocolate (63 grams - a third cup of chocolate chips - per week) had a 17% lower risk of stroke than men who never, or very rarely, ate chocolate. Also, for each additional 50 grams of chocolate consumed per week (a quarter cup of chocolate chips), there is a fall in stroke risk of about 14%. Many researchers maintain it is dark chocolate that is good for the heart, but about 90% of the chocolate intake in this study was milk chocolate. Karolinska Institute, August 2012
