Again, you’re asking for behavioral change in humans by fiat. Fortification extends well beyond just adding vitamins to chips or junk food. It’s added in many basic building blocks (milk, and most flours and rice) because it literally is solving nutritional deficiencies caused by poverty. Nobody is somehow making purchasing decisions on junk food based on fortification content.

> Get the shit like food coloring and corn syrup out of our food.

Irrelevant to nutritional content, unless you mean overly sugary foods relating to corn syrup. Which, you can have the exact same health outcomes and hyper palatability by just using regular old sugar.

> Other nations do just fine with their food situation without all this made up nonsense and excuses like "fortified" food.

Other nations fortify their food too, including many “first world” countries. I don’t know why you think this is somehow a uniquely American thing.
