A new study found that the number of United States kids gulping fast food on any given day has been declining. The study, which included data from 2003 to 2010, found that calories from some types of fast foods have also declined.

Co-author of the study, Colin D. Rehm from Tufts University in Medford, Massachusetts, said that some previous studies had included menu item, but the new study actually considered what Children across the country are eating. While talking to Reuters Health, Rehm said, "The take-home message is that changes can be made, whether they are due to consumer preference or due to what the restaurants have done themselves. It shows that change is possible".

As per data collected by the National Health and Nutrition Examination Surveys, in 2003, about 39% of the United States kids consumed fast food on a given day, while during a survey in 2009-2010 survey, less than 33% kids ate fast food.

The new study has found that calorie intake from foods like burger and pizza also declined, while calorie intake from Mexican foods and sandwiches remained the same. According to the study, sandwiches and Mexican food were minor to the total fast food consumption.

The study has been published in JAMA Pediatrics, which suggested that some other sources noted decline in pizza sales since 2003. Rehm further said that increased consumer nutrition awareness and restaurant reformulations of menu items also affected the trend. The author also said that by 2010, fewer kids visited fast food restaurants every day. They consumed fewer calories even when they visited pizza restaurants.

For burgers, calories declined but the number of visitors per day did not, which indicated that kids started making lower-calorie choices at burger restaurants, according to Rehm.
