In a survey that might have been taken at Lake Wobegon, where all the children are above average, people asked to grade their diet gave themselves a B- while saying that everyone else’s diet deserves only a C-.

That’s according to the 2013 Food and Health Survey, which was commissioned by the International Food Information Council Foundation. The survey includes responses from 1,006 Americans between the ages of 18 and 80. The survey was conducted in April.

In the survey, 88% of respondents said that it’s possible to have “a great deal” or “complete” control of their diet, but only 66% said they try to take that amount of control over what they eat.
