Everyone has an opinion about fast food. Some love it, some hate it. Some say it will kill you and others say it does no harm. There's no real truth about fast food, it's going to affect everybody differently, but there are some assumptions being made that are incorrect.
For instance most people think that poor people eat more fast food than wealthy people, but is that true? That was the question that was the question that University of Michigan professor Patricia Smith wanted to answer, so she launched one of the most comprehensive studies of its kind.
The idea that poor people eat more fast food isn't a strange one. Fast food is cheaper and more readily available than restaurant meals and even some groceries. Making meals at home takes planning, time and money - luxuries that many low income families can't afford when they bustle from 1 minimum wage job to the next.
Grabbing a Big Mac is going to be a lot easier than making a casserole.
The rational was so prevalent that in 2008 the city of Los Angeles restricted the amount of fast food restaurants in low-income neighborhoods, presumably trying to protect lower-income citizens from themselves.
Smith wasn't sure that the truth was so cut and dry.
"If we're going to have legislation than maybe we ought to have facts," she said on Michigan Radio.
