Does burning your food increase your risk of getting cancer?
I've been told that I shouldn't eat charred meat (and at least sweep the charring off of a barbequeued sausage), because it can cause cancer. I've had a look at what I can find on the subject, and it seems a little open to interpretation to me (one study I looked at could equally have been interpreted that a genetic predisposition to enjoying well-cooked meat increases the probability of cancer.)
Is there any hard science on the subject?
