Everything is a chemical. Salt is sodium chloride. Ingredients should be assessed individually and scientifically for their safety. Not just scary name equals unsafe. That's childish.
The war on monosodium glutamate is based racism and not science. It's as safe as table salt. There is no real science showing that it's anything but delicious.
Dextrose is just a simple sugar. It's essentially glucose chemically. Nothing to worry about. Your body produces glucose itself. You are not ultra processed because of that fact.
High fructose corn syrup is just fructose, another simple sugar [1], and there's no real science to back up all the fear mongering around it. It's no worse for you than any other sugar. All things in moderation.
