It really depends on what country you’re talking about. For instance, a preferred food in America is actually the hot dog, despite the questionable ingredients. This is partly because the food companies, for a long while, were used to be able to hide what they were using to make the food.
When the Food and Drug Administration - or the FDA - was created, this practice quickly came to an end. However, now hot dog vendors must show that they are using these questionable ingredients - which means they are usually no longer used for this purpose. Other favorite foods in America include soft drinks, hamburgers, and anything sweet. As a nation, America has a serious sweet tooth. Not the most glamorous thing, but there you have it.
