Ewwww.... I thought that article might be exaggerating so I looked up some others:
Red cochineal beetles, when dried and crushed, produce a powder called carmine, which is used as an all-encompassing dye in red foods like candy, ice cream, and yogurt. Though it previously slipped under the radar as "artificial coloring," the FDA has required manufacturers to explicitly list carmine on food labels since early 2011.
Edible shellac, also known as confectioner's glaze, coats most hard, shiny candy, with the notable exception of M&Ms. It's made from the excretions of female lac bugs (Kerria lacca).
Gross. There was another conversation about eating bugs in the future which I thought was unlikely, but I guess we're already a little bit there.
