Interestingly, several of the fast food chains started to get serious about producing real salads -- and selling them -- in 2003. You can find food reviewers talking about them around then. Fast-food salads existed before that, as a kind of throw-away item. I got the impression (from eating them) that they were the parts of the trimmings for the burgers that were leftover. Waste not, want not, yeah?

The focus of Supersize Me wasn't just high-cholesterol, high-fat diets, but overeating in general. Merchandizing the Supersize as a bargain is basically selling gluttony retail. And when did anyone Supersize a salad?

It's not only about content, but portion control as well. And that is the point of the movie, as its title indicates. You never see the Quaker Oats people promoting a Supersize instant oatmeal packet. Though that instant stuff has too much sugar and enough extra sodium to make things interesting.

I bet I could become morbidly obese eating too much oatmeal. It's harder to do, but with enough sugar, and cream instead of milk (that's tasty, too), and maybe even a pat of butter, I could do it. I knew a guy, obese in his youth, who ate Cream of Wheat every day for breakfast -- that's healthy, right? -- with milk and a half-cup of jam stirred in, enough to fill a small vegetable serving dish. As you said, moderation is the key.
