"Nutrition Facts" labels are required for most foods sold in the United States. In June 2014, the Food and Drug Administration (FDA) proposed key changes to the labels, to feature clearer information about calories, fat, and sugar.

To find out whether mothers and fathers use nutrition labels differently, a random sample of 770 mothers and a random sample of 711 fathers were polled. Below are the results to the question: "When you buy food and drinks at a store, how often would you say that you read the labels that include nutrition information?"
