Sure. In any given case, they may or may not be bad for you. But in accepting processed foods over home grown, you are taking on faith that the provider shares your values. (Would they add more sugar and salt than you would to improve taste? Would they put in additives you wouldn't, and hide them under funny names?)

I'm not an off-the-reservation eat everything raw person, but I am skeptical that most managers would make food less addictive to make it healthier. There are exceptions, but this is one of the negative aspects of a market economy.
