Myth: Chocolate is high in caffeine.
Fact: While eating chocolate may perk you up, chocolate is actually not very high in caffeine. A 1.4-ounce chocolate bar or an 8-ounce glass of chocolate milk both contain 6 mg of caffeine, the same amount as a cup of decaffeinated coffee. (For reference, regular coffee contains about 65-135mg of caffeine.)
Myself: Chocolate, especially dark chocolate, is very beneficial to you in small portions. Eat some, enjoy it, and don't eliminate it from your diet!
