With a -8 vote, I’m not going to comment on eating real food ever again here. :)

If you genuinely care and aren’t just baiting me, thinking you’ve entrapped me in an illogical box, here goes. I don’t have a problem fortifying cereal or flour, but they are both moderately to highly processed, so it’s generally better to eat less processed food. Salt is minimally processed and is an essential mineral, as is iodine. If you eat a good diet, you don’t need extra iodine, but I don’t think it’s harmful to add it. You can choose uniodised salt if you feel you don’t want extra iodine. Adding these things doesn’t make them more processed, it just makes them the same but with additives. :) Processing means you are taking a real food and removing nutrition from it in exchange for getting something in return like better shelf life or faster cooking times or some other convenience.

Better how? Certainly not more nutritious but having some new feature that adds convenience or uniformity. Processing always has side effects, usually discovered decades later. Trans fats, artificial sweeteners, refined grains, the list goes on.
