I think Demi Lovato but... this is dumb, and also she's misusing her platform by punching down.
Her justification for renaming certain foods like "For celiac" or "diabetic," is flatly wrong, as well. Diabetics can eat sugary treats, it's all about balance. And non-diabetics can enjoy sugar-free foods. Same with people who might want to avoid certain foods but don't have celiac disease. My wife will sometimes avoid gluten for whatever reason, she doesn't have celiac disease. The idea that diabetics can't eat sugar is straight out your grandmother's 1950s understanding of diabetes.
(my sister developed type 1 diabetes as an adult, "childhood diabetes," as it used to be called, and one of the most frustrating things for hr was old people who didn't understand that their 1970s concept of "If you have diabetes you can't eat ANYTHING with sugar" is straight up false... my loving grandmother used to ignorantly make comments all the time like, "ohh.. can you eat that?" if my sister wouldhave a slice of cake or w/e)
