I like truthful and "complete" information on food labels.
I like it more now than I did a few years ago, because 2 of my 3 kids have serious food allergies and it is important to know exactly what's in those foods. My oldest son went into shock from a tiny sample of spaghetti sauce, processed in a factory that also processed peanuts. The notice was in teeny tiny print on that label and we missed it, almost killed my kid. My youngest son is allergic to eggs and milk. So they could cover the entire product with information on what the food product is made of, and that would be a really good thing for me and my family.
I don't think it can even be considered a burden on the food manufacturer/producer. If they don't know whats in it, they shouldn't be selling it as food.
