Subway
Subway sandwiches have been riddled with controversy for a number of reasons. For one thing, the footlong sub is reportedly not actually a foot long. And recently, the popular restaurant chain came under fire when it was revealed in a study that their tuna sandwiches were found to contain no actual tuna. While the study didn’t reveal what was actually in the fish mixture served on the restaurant’s sandwiches, it was revealed that the fish was composed of a variety of different ingredients, none of which were tuna fish.
