Why Does Bad Food Taste So Good?

Fairy Godmother: I don't care whose fault this was, just get it sorted! And could someone please bring me something deep fat fried and smothered in chocolate...Shrek 2

Like the Fairy Godmother, I'm interested in food that's really really bad for me when things go wrong, or when things go right, or.. just about any time. So why is the bad food so darn tasty? It's not fair.. why can't celery be bad for you? I guess in general I have given up most bad for me things, but I can't let go of pizza. I eat homemade, which is better for you, lower in fat, and eat lower fat ingredients like ham and green olives (which have healthy, not bad for you, fat), my favorite! I even cut the vegetable oil out of my pizza sauce! That's when we're good and cook at home, though, sometimes just a great big "insert chain name here" meal sounds so good. I think that's what we're doing tonight.. you have to be bad sometimes!
