We learned that men who eat chocolate might have a decreased risk of stroke. 

According to a Swedish study of more than 37,000 men over 10 years, men who regularly ate chocolate had a 17 percent lower risk of stroke than men who did not eat as much chocolate.

The men who saw the most stroke-thwarting benefits typically ate about a third of a cup of chocolate each week. 

Researchers were careful to note that the findings were merely observational and do not imply a direct link between decreased stroke risk and chocolate specifically.  But they did point out that the flavonoids in chocolate have been shown to have positive effects on blood pressure, cholesterol and blood vessel function.

Flavonoids are also found in berries, kale, spinach, soy and tea.
