 So I'm guessing, I don't know this, please correct me if I'm wrong, you know, almost all coloring dyes are highly allergy-producing, causing, and they could be a problem. So I would avoid all food colorings. So I don't know the fact, somebody has to investigate this, whether they add any red dye to the ketchup to make it so nice and red, because when you cook tomatoes, they are not bright red anymore.
