Contrary to what many believe, chocolate is not high in caffeine. The amount of caffeine in a typical 1.4 oz. An ounce of bittersweet chocolate has more, from 5-35 mg caffeine and 1 ounce unsweetened baking chocolate has 35 mg. These levels are all well below the 140 mg that is in a cup of brewed coffee. Stimulant effects of caffeine can be initiated after consuming 150-200 mg, but this varies from person to person.
Chocolate causes cavities.
Susceptible teeth, dental plaque, and food cause cavities. Cocoa and chocolate actually have the ability to offset the acid-producing potential of the sugar they contain. Milk chocolate has a high content of protein, calcium, phosphate and other minerals, which have protective effects on tooth enamel. Also, since it contains fat, milk chocolate clears the mouth relatively faster than other candies, so milk chocolate may be less cavity causing. Remember that the best way to prevent cavities is to regularly use fluoride, practice proper oral hygiene, and visit your dentist.
