Look online and you will find a slew of information on how chocolate is good for you. It can cure everything from depression to some types of cancer, can help you lose weight and even improve cognitive abilities. On a closer examination, you will find that the studies cited have been funded at least in part by major chocolate manufacturers and examine cocoa powder rather than chocolates themselves.
For starters, cocoa powder has a distinctly bitter taste - milk solids and sugar are added to sweeten the taste to make most chocolate. In the refining process, much of the benefits of cocoa powder are blunted. In fact, even if you had raw cocoa powder, you would need to have it in large quantities before there are any health benefits.
Cocoa has an abundance of flavonols which is responsible for the many health benefits. Flavonols are plant-based catechins that are known to have anti-inflammatory effects. So while there may be some health benefits of eating raw cocoa, remember that they are virtually non-existent in chocolate. Dark chocolate, which has a higher proportion of cocoa, is a better option, but still should not be considered a health food.
This doesn’t mean that you shouldn’t eat chocolate—just do it moderately. The fact that you find it delicious and it cheers you up is enough reason to enjoy it. (Read more: Why does chocolate make you happier?)
