  • Interesting fact: Chocolate not only does not promote tooth decay, it might prevent it. According to the American Dental Association, milk chocolate contains ingredients, such as calcium and phosphate, that might modify acid production in the mouth that leads to cavities. Some oils in chocolate might also prevent tooth decay. Chocolate does contain sugar, of course, but these are simple sugars that are less harmful than the complex sugars contained in other foods.
