You're not wrong! But people these days. We're all getting lazier and eating much larger portions. You can't even get a reasonable sized soda if you go to a fast food restaurant. I don't prefer fast food, so I avoid it most of the time.
I regularly eat Cheetos, as part of what I call the “salt” group. If you constantly drink tons of water, you need way more salt than what’s recommended. Cheetos aren’t really bad for you.
