Theobroma means, appropriately, "food of the gods." Contrary to popular belief, chocolate has little caffeine; its main stimulant is the much milder theobromine. The darker the chocolate, the higher the content of theobromine.
Cacao beans are extremely rich in the antioxidant compounds flavonoids, phenols, catechins, and procyanidins; dark chocolate, in fact, has four times the antioxidant content as tea, and one and a half ounces of it have about the same amount as a glass of red wine. (Dark chocolate has twice the antioxidants of light, and white chocolate has none.) Chocolate also contains significant amounts of iron, magnesium, and phosphorus.
Chocolate causes the brain to release endorphins, the natural opiates that are our pleasure chemicals; and phenylethylamine, another compound in chocolate, is thought to stimulate the same physical reaction as falling in love. The smell alone slows brain waves, inducing a sense of calm.
Possible good news for headache sufferers: because cocoa reduces the blood platelet adhesion that can lead to headaches, it may be a headache reliever. Research has also shown that parts of the cocoa bean fight mouth bacteria and stop dental decay.
The quality of the chocolate makes all the difference. The key is to eat high-quality dark chocolate with a 60 to 70% cocoa solid content. Normal dark chocolate has around 30%; ordinary chocolate has as little as 10 to 20% cocoa content, with a lot of sugar and hydrogenated vegetable fats. Dark chocolate is actually quite low in fat and sugar; the fat in cocoa is stearic acid, some of which converts in the body to oleic acid, a monounsaturated fat similar to that found in olive oil, well known for its health benefits. The Swiss eat the most chocolate of anyone--about twice as much as Americans--yet they have among the lowest obesity rates.
So forget the guilt; go ahead and enjoy your chocolate. And while you're at it, get chocolate with nuts. They're a tremendous source of vitamin E, heart-healthy fats, and virtually no saturated fats. Just remember to make it dark chocolate, and to indulge in moderation.
