Yeah actually there are multiple studies that show direct health benefits of natural cocoa.
Keep in mind she isn't selling coffee or trying to tell you to treat something with it. She's explaining a recipe she made.
Would you like her to cite her sources better?

As for flagging this, that's abuse of flagging. Flags are for the following...
Spam (she's not selling anything and this is not a commercial post that is in any way off topic), abusive content (no abuse in fact she's being quite friendly), or copyright violation (she made this one up herself).

You just used it as your own personal disagree button. I don't believe in retaliatory flagging myself, but if you keep using flagging as your own personal "i disagree with you" button you may find someone who disagrees with your abuse of the flagging system. So think before you flag in the future.

Commenting would have been just fine.
