Study: Fast Food May Not be So Bad After All

By Jacob Sullum

A common assumption of anti-fat crusaders, ranging from Super Size Me director Morgan Spurlock to the backers of restaurant restrictions in South L.A., is that poor people are especially apt to be overweight largely because they eat so much fast food, which supposedly is cheaper than healthier options. 

But a recent study led by J. Paul Leigh, a professor of public health sciences at U.C.-Davis, finds that poor people eat in fast food restaurants less often than the middle class.

Looking at data from the Continuing Survey of Food Intakes by Individuals and the Diet and Health Knowledge Survey, Leigh and co-author DaeHwan Kim found an inverse relationship between income and fast food consumption up to an annual household income of $60,000. Beyond that point, people were less likely to eat fast food.

"There is a correlation between obesity and lower income, but it cannot be solely attributed to restaurant choice," says Leigh. "Fast-food dining is most popular among the middle class, who are less likely to be obese."
