Breakfast cereal is generally pure garbage, so I'm happy enough about this score, but a globally applied linear "goodness" scale on foods is too simple to be accurate. Food is good for you, or not, in context of the rest of your diet and, maybe to a lesser extent, your lifestyle/values/goals.
This isn't telling you what to eat, but it is giving you a tool that you can use to decide if you want to eat it. You know, while you take into consideration your own overall diet and personal taste. It makes make doing this stuff easier, at least to some folks.
You don't have to use a tool available to you if you don't like it.
