Try making sure what you’re saying is correct before confidently talking out of your ass:

This is the nutrition label for Wonder Bread, the epitome of trashy American sandwich bread. It does not contain high fructose corn syrup. What it does contain, however, is sugar. As I said, high fructose corn syrup is not worse than sugar anyway, and all bread has sugar in it because it’s necessary for the yeast to rise. American-style sliced sandwich bread does tend to be sweeter than the round sort, but that’s not a high fructose corn syrup problem. Even if it did have high fructose corn syrup, that literally wouldn’t change anything about its health value.

Again, high fructose corn syrup is not worse than sugar. If every product in the world that uses sugar were reformulated to use an equivalent amount of high fructose corn syrup, health-wise nothing would change (but the flavour may be different). Decrying high fructose corn syrup but being okay with sugar is just ignorance of science, full stop.

If corn were as cheap everywhere else around the world as it is in America, literally every country would have processed foods containing high fructose corn syrup instead of sugar, because it is basically completely the same.

Edit: And before you make a comment talking about the length of the ingredients list, it’s partially because American food labelling laws are way stricter than elsewhere in the world, requiring manufacturers to label far more ingredients and with far more detail. Sliced sandwich bread sold elsewhere is probably made of exactly the same stuff, but the manufacturer probably just isn’t legally required to tell you about it.
