Since the article didn't list many examples, I looked them up.
brominated vegetable oil- used in sodas, usually citrus flavored ones
potassium bromate- look out for this in breads
propylparaben- used in packaged baked goods, mostly pastries and tortillas
red dye No. 3- aka Erythrosine, its a pink dye, so watch out for that ingredient in any pink foods
and lastly to cover all bases:
titanium dioxide- its a white dye, so watch out for that ingredient in any white foods
