So the FDA is letting companies change the ingredients in foods without listing the changes on the labeling.
As an American with an allergy to a commonly used food group, this fucks with my health directly.
Considering the millions of people in America with food allergies of various kinds, this will probably kill people.
Supposedly it only applies if the "ingredient being substituted for the labeled ingredient does not cause any adverse health effect (including food allergens, gluten, sulfites, or other foods known to cause sensitivities in some people, for example, glutamates);" but it also implies a likely shortage of testing capacity, so if it's under 2% change companies just pinkie promise they didn't replace smth for smth more dangerous but cheaper.
