Yes, I know, I follow this stuff..... I don't eat a lot of things for the same reason....it was simple curiosity. And for the record, I eat lo to no sodium food, have for years. Even when I was eating more junk, I preferred no salt chips and I have never salted eggs.
There are a lot of foods out there, called "Natural" that have long technical names in their descriptions because if they wrote the common name, no one would eat them. And they are not regulated by the FCA because the FDA does not see them as food...example, see wood pulp in bread (occasionally listed as powdered cellulose) And then look up where "Carmel Color comes from.
