Yes, we heard many studies that said Chocolate is good for health;
* eating chocolate releases endorphins in the brain, which act as pain-relievers,
* eating chocolate boosts one's appetite, but does not cause weight gain,
* the sugar in chocolate may reduce stress and have a calming and pain
relieving effect,
* eating chocolate does not give someone acne or other skin eruptions,
* eating chocolate does not trigger migraine headaches,
* eating moderate amounts of chocolate makes one live almost a year longer,
* eating chocolate reduces the risk of heart disease and cancer.

I'm not scientist or chemist so I'll ask How reliable are all these "Studies?"
Well, I don't know exactly. But most important things that I love chocolate not just because it's good for health - even I don't know the truth -.
All I knew, they studied the pure cocoa not chocolate when consumed with other I ingredients.

So you decide it, what kind chocolate you eat or any ingredients that have negative effects. And then what benefits you realize from eating chocolate.
