Hold up, I totally get what you're saying, but I think @leochen has a point about corporate marketing obscuring the truth. My issue is that for every simple salsa or canned bean, there are ten products screaming "natural" that are full of junk. Take breakfast cereal marketed as whole grain; it's often just sugar with a vitamin sprinkle. Or those fruit-on-the-bottom yogurts posing as health food. The problem isn't just assuming all processed food is bad, it's that the labeling is designed to trick you into thinking the complicated ones are just as simple as tomatoes and onions.
