Betsy Ann, Sarris, and Hershey are some of my favorite brands of chocolate. It gives me that mid-afternoon boost of energy, improves my mood, and not to mention tastes delicious. If consumed in moderation some kinds of chocolate can actually be good for you.
In the CNN article (linked below) I read, they performed research at Tufts University. Jeffrey Blumberg, director of the Antioxidants Research Laboratory found hypertensive people who ate 3.5 ounces of dark chocolate per day for two weeks saw their blood pressure drop significantly. Also, chocolate milk may help you recover after a tough workout.
Of course with all the calories chocolate has, it should not be a substitute for fruits and vegetables, you need the vitamins, and potassium that they provide your body.
