Cocoavia Health Facts : Fortified chocolate good for heart, but there's a catch

Chocolate is typically not part of a heart-healthy diet. But what if chocolate delivered substances that are good for the heart? Mars, the maker of M&M's and other sweet treats, is rolling out CocoaVia, a line of chocolates laced with plant sterols and flavanols for what Mars calls "real chocolate pleasure, real heart health benefits." But there's a big catch, reports the Harvard Heart Letter.

Eating plant sterols can lower cholesterol, and flavanols may keep healthy arteries flexible. But you must eat two portions of CocoaVia every day to get the amounts necessary to do this. That means a daily dose of sterols and flavanols comes with an extra 200 calories and 36% of the daily recommended limit for saturated fat. If you don't cut back 200 calories somewhere else — or walk an extra 45 minutes — that would translate into a 20- pound weight gain over the course of a year. That's more than enough to counteract any benefits from sterols and flavanols.
