Everyone Eats Fast Food - Even Rich People

The commonly held belief that only poor people eat fast food is a myth, according to researchers.

Investigators from the Ohio State University and the University of Michigan-Dearborn reached that conclusion after conducting a new nationwide study of young baby boomers.

Results showed that middle-income Americans were most likely to eat fast food, although the differences from other groups was relatively small. Even the richest people were only slightly less likely than others to report fast food consumption.

“It’s not mostly poor people eating fast food in America,” said Jay Zagorsky, co-author of the study and research scientist at Ohio State’s Center for Human Resource Research. “Rich people may have more eating options, but that’s not stopping them from going to places like McDonald’s or KFC.”

Zagorsky, who also has an appointment with the Ohio Education Research Center, conducted the study with Patricia Smith of the University of Michigan-Dearborn. Their study was recently published online and will appear in the November 2017 issue of the journal Economics and Human Biology.

The researchers used data from the National Longitudinal Survey of Youth, which has questioned the same group of randomly selected Americans since 1979. The NLSY is conducted by Ohio State’s Center for Human Resource Research.

In the study, Zagorsky and Smith used data from about 8,000 people who were asked about their fast-food consumption in the 2008, 2010 and 2012 surveys. Participants, who were in their 40s and 50s at the time of the surveys, were asked how many times in the past seven days they had eaten “food from a fast-food restaurant such as McDonald’s, Kentucky Fried Chicken, Pizza Hut or Taco Bell.”

Results were compared with the participants’ answers to questions about their wealth and income. While there were some slight differences in how wealth and income were related to fast-food consumption, Zagorsky said the results were similar.

Overall, 79 percent of respondents ate fast food at least once and 23 percent ate three or more meals during any one of the weeks recorded in the study.

In one analysis, the researchers divided the participants into 10 groups based on income. About 80 percent of those in the lowest 10 percent of income ate at least once at a fast-food restaurant, compared to about 85 percent of those who were ranked near the middle (40 to 50 percent) in terms of income. Of the richest 10 percent, about 75 percent reported eating at least one fast-food meal.

The number of fast-food meals eaten during the three weeks of the study showed a similar pattern. The lowest 10 percent in terms of income ate about 3.6 fast-food meals during the three weeks of the survey, compared to about 4.2 meals for middle-income people and three meals for the richest 10 percent of participants.
