Subway says an ingredient dubbed the ""yoga mat"" chemical will be entirely phased out of its bread by the week of April 14, 2014. The disclosure comes as Subway has suffered from an onslaught of bad publicity since a food blogger petitioned the chain to remove the ingredient. (AP Photo/Seth Wenig, File)"
