Do French Fries cause cancer?

A poster adorning the walls of KFC restaurants in California may just take your appetite away. Or at least make you consider giving up the fries. Here's what it says: "Cooked potatoes that have been browned, such as French fries, baked potatoes and potato chips, contain acrylamide, a chemical known to the state of California to cause cancer."

Is California really privy to some information that has eluded the rest of the world? No. But the state does have a unique law, Proposition 65, which states "no person in the course of doing business shall knowingly and intentionally expose any individual to a chemical known to the state to cause cancer or reproductive toxicity without first giving clear and reasonable warning to such individual."

So, is the warning about acrylamide reasonable?
