This is fair, but I think overstated. It's possible to preserve a tortilla for a few days without exotic additives. I'm not even criticizing sodium, although that's not a lot better. And yes, preservatives are better than eating spoiled food.
The problem is when the whole supermarket is full of highly preserved food, then this is normalized and health consequences are obscured. The deeper issue is that for perhaps 80% of people this is fine and profitable, but for let's say 20% it introduces weird, hard to trace health problems, which don't appear to come from the supermarket because all the normal foods are like this.
