Researchers have pinpointed the reason dark chocolate is good for your heart.
Dark chocolate helps restore flexibility to arteries while also preventing white blood cells from sticking to the walls of blood vessels, researchers from Wageningen University in the Netherlands found.
For the study, 44 middle-aged, overweight men ate 70 grams of chocolate over two periods of four weeks. They received either dark chocolate with high flavanol content or regular chocolate and the researchers recorded the effects.
The study appears in the FASEB Journal (Federation of American Societies for Experimental Biology).
"The effect that dark chocolate has on our bodies is encouraging not only because it allows us to indulge with less guilt, but also because it could lead the way to therapies that do the same thing as dark chocolate but with better and more consistent results," FASEB Journal editor Gerald Weissmann said in a press release.
