Does chocolate cause cavities?
Not necessarily. According to a recent study by Osaka University in Japan, cacao contains antibacterial agents that actually fight tooth decay.
However, most mass-produced chocolate contains sugar, which is known to cause tooth decay and probably counteracts the benefits of these agents.
Does chocolate cause acne?
Not according to studies performed by the Pennsylvania School of Medicine and the U.S. Naval Academy. Eating or not eating chocolate made no difference in the skin condition of the study participants.
In fact, most doctors believe that acne is not linked primarily to diet.
Will the caffeine in chocolate make me jittery?
Probably not. Cacao does contain a number of stimulants, such as caffeine and theobromine, but in small amounts that are diluted even further when processed into chocolate. In fact, one ounce of milk chocolate contains about the same amount of caffeine as one cup of decaffeinated coffee.
Interestingly, one study has shown that the smell of chocolate may actually relax you by increasing theta waves in the brain.
Can chocolate cause headaches?
There is little evidence of this, according to research conducted by the University of Pittsburgh. However, some studies suggest that chocolate may trigger headaches specifically in migraine sufferers.
Is chocolate an aphrodisiac?
Not really. Chocolate contains small amounts of a chemical called phenylethylamine (PEA), which is a mild mood elevator. It’s the same chemical that our brain produces when we feel happy or “in love.”
The mild “rush” we get from this substance may be why some people say they’re “addicted” to chocolate.
