I'm really curious about what you guys have to say about this.

For the longest time: I've added fresh-cracked pepper to almost anything. I love the sensation and it's versatility. My additional motivation was because I heard that: Spicy items; especially black pepper, help speed/excersise your metabolism.

I was chatting with someone in the office last week:
they tell me this is actually a myth and that there are actual reasons not to add it...(and rather to choose cayanne instead).

Serious Eaters: Do you love black pepper?
What do you know about this myth/non-myth?
Do you have any resources you can share?
TIA dudes :D
