Chocolate is healthier than many fruit juices and is a `superfood` in its own right, says a new study conducted by a US-based chocolate company. Superfoods are high in anti-oxidants and compounds that help prevent damage to healthy cells.   Researchers from the Hershey Centre for Health & Nutrition in the US found that powdered dark chocolate had more anti-oxidants and polyphenols, believed to protect us from cancer and cardiac conditions, the Chemistry Central Journal reports. They compared single servings of dark chocolate, cocoa, and hot chocolate mix with fruit juices including acai berries, cranberries and pomegranates, according to a Hershey statement. The research showed that both dark chocolate and cocoa had more antioxidant activity and more flavonols than fruit. Debra Millar, who led the study, said chocolate should be labelled a \"superfruit\".
