A new study has found that dark chocolate is better for heart than fruit juices. The study published in the Chemistry Central Journal said that dark chocolate and cocoa are good for heart because they have more anti-oxidant capacity than fruit juice. The study added that chocolate products also have more heart-healthy flavanols and polyphenol, but these substances are not found in hot cocoa mix as it is processed. "When looking for a sweet snack, a square of dark chocolate might, in fact, be your healthiest choice," said Suzanne Steinbaum, a cardiologist at Lenox Hill Hospital in Manhattan to New York Daily News.
