while I am neither for nor against the Cancer Project, I do agree that most of the "food" (and I use that term loosely) found at Fast Food establishments is a complete abomination. Plying your body with those kinds of chemicals and preservatives on a constant basis is not, IMO, healthy. I believe the reason why many people are overweight and unhealthy is due to too many foods like these in their diets and not enough fresh fruits and vegetables and free-range meats (I'm NOT anti-meat) but plying any animal full of steroids in order to get them fatter is not good for anyone.
And if it is a time thing and an "I don't want to cook thing" there are plenty of establishments that offer carry out which are far healthier and tastier than Mickey Ds, Burger King, Whataburger, etc...
