Superfoods don't just come from your supermarket's produce aisle. In fact those chocolate candy bars next to the gummy bears now qualify. Study after study proves that dark chocolate—sweet, rich, and delicious—is good for more than curing a broken heart.
The secret behind its powerful punch is cacao, also the source of the sweet's distinct taste. Packed with healthy chemicals like flavonoids and theobromine, this little bean is a disease-killing bullet. The only problem? Cacao on its own is bitter, chalky, nasty stuff.
Here, 9 sweet health benefits of chocolate.
The latest research backs up claims that chocolate has cardiovascular benefits: In a 9-year Swedish study of more than 31,000 women, those who ate one or two servings of dark chocolate each week cut their risk for heart failure by as much as a third.
Wish that was a serving each day? Another big, long-term study in Germany this year found that about a square of dark chocolate a day lowered blood pressure and reduced risk of heart attack and stroke by 39 percent. Most of the credit goes to flavonoids, antioxidant compounds that increase the flexibility of veins and arteries.
But since those antioxidants come with a generous portion of sugar, milk, and butter, chowing down on chocolate isn't an excuse to skip your workout. Chocolate and exercise actually work surprisingly well together: Another recent study, out of Australia this time, showed that eating chocolate high in healthy antioxidants reduced the blood pressure-raising effects of exercise on overweight individuals. So go ahead and reward yourself. A chocolate bar has five times the flavonoids of an apple, after all.
If you're wondering how you can add dark chocolate to your diet plan without putting on pounds, the good news is that it should be easier than you expect.
Researchers from the University of Copenhagen found that dark chocolate is far more filling, offering more of a feeling of satiety than its lighter-colored sibling. That is, dark chocolate lessens cravings for sweet, salty, and fatty foods. So if indulging in a bit of healthy dark chocolate should not only make it easy for you to stick to the small portion recommended for optimal health, but it should make it easier for you to stick to your diet in general. Jackpot!
Women who ate chocolate daily during their pregnancy reported that they were better able to handle stress than mothers-to-be who abstained. Also, a Finnish study found their babies were happier and smiled more. Hmm, so your options are popping a piece of premium chocolate or sticking a pacifier in your screaming baby's mouth?
Candy as a diabetes foe? Sure enough. In a small Italian study, participants who ate a candy bar's worth of dark chocolate once a day for 15 days saw their potential for insulin resistance drop by nearly half. "Flavonoids increase nitric oxide production," says lead researcher Claudio Ferri, M.D., a professor at the University of L'Aquila in Italy. "And that helps control insulin sensitivity."
UC San Diego researchers recently confirmed what your fat pants could have told them back in college: When times get tough, people tend to dip into the chocolate stash more often than they might otherwise.
And as it turns out, that kind of emotional eating might not be such a bad thing. You know what kind of havoc stress and its sneaky sidekick cortisol can wreak on your body. Swiss scientists (who else?) found that when very anxious people ate an ounce and a half of dark chocolate every day for two weeks, their stress hormone levels were significantly reduced and the metabolic effects of stress were partially mitigated. After a breakup, break out a dark chocolate bar rather than a pint of ice cream.
London researchers recently tested chocolate flavanols' sun-protecting prowess. After 3 months eating chocolate with high levels of flavanols, their study subjects' skin took twice as long to develop that reddening effect that indicates the beginning of a burn.
Subjects who ate conventional low-flavanol chocolate didn't get the same sun protection. Watch for brands boasting high levels of the healthy compounds.
Next time you're under pressure on a work project, don't feel so guilty about grabbing a dark chocolate bar from the vending machine. Not only will it help your body ward off the effects of stress, but it'll boost your brain power when you really need it.
A University of Nottingham researcher found that drinking cocoa rich in flavanols boosts blood flow to key parts of the brain for 2 to 3 hours, which could improve performance and alertness in the short term.
Other researchers from Oxford University and Norway looked at chocolate's long-term effects on the brain by studying the diets of more than 2,000 people over age 70. They found that those who consumed flavanol-rich chocolate, wine, or tea scored significantly higher on cognitive tests than those who didn't.
One study found that chocolate quieted coughs almost as well as codeine, thanks to the theobromine it contains. This chemical, responsible for chocolate's feel-good effect, may suppress activity in a part of the brain called the vagus nerve.
Maria Belvisi, a professor of respiratory pharmacology at the National Heart and Lung Institute in London, says, "It had none of the negative side effects." Codeine makes most people feel sleepy and dull—and doesn't taste anything like fine chocolate.
Both South American and European cultures have a history that dates back to the 16th century of treating diarrhea with cocoa. Modern-day science has shown they were onto something.
Scientists at the Children's Hospital Oakland Research Institute found that cocoa flavonoids bind to a protein that regulates fluid secretion in the small intestine, potentially stopping the trots in their tracks.
