Consuming flavonoid-rich tea and chocolate in moderation can be associated with reduced risk of cardiovascular disease, according to a Penn State -led review of 66 published studies on the issue. Lead-researcher Dr Penny Kris-Etherton, a professor of nutrition at Penn State, commented: "Since tea, without milk or sugar, contains no calories, it's an ideal way to add antioxidant flavonoids to your diet without increasing your weight. Having a chocolate cookie that also contains fruit and nuts along with the tea, if consumed in moderation, can be a heart healthy snack."
