Chocolate is said by some to be good for your health, states the newspaper Nihon Keizai Shimbun of Japan. Why? Because chocolate contains cocoa polyphenol, which helps to inhibit arteriosclerosis and cancer. Additionally, chocolate is said to be effective in balancing the immune system and helping the body to recover from stress. Professor Hiroshige Itakura of Ibaraki Christian University says: “High quality chocolate that uses plenty of cocoa beans and very little sugar and oil is the most effective.” However, the professor also stressed the importance of eating “green and yellow vegetables and proteins containing the different kinds of polyphenol” that the body needs.
