A recent study published in Pediatrics says pizza consumption is a top contributor to children's and adolescents' caloric intake.
But just how much is too much?
Dr. Tara Narula tells "CBS This Morning" that on an average day, approximately 22 percent of American children aged six to 19 are eating pizza.
The study, which was put forth to examine children's pizza consumption patterns, also examined the impact on children's energy and nutrient intake.
Data was drawn from the National Health and Nutrition Examination Surveys of 2003-2004, 2005-2006, 2007-2008 and 2009-2010.
The researchers tested the changes in consumption patterns throughout the years, including by race/ethnicity, income, meal occassion and source.
According to the article Energy and Nutrient Intake From Pizza in the United States, the individual-level fixed effects regression effects estimated the impact of pizza consumption on total energy intake, or TEI, and also that of sugar, saturated fat and sodium.
The results found that for children and adolescents, respectively, pizza consumption was "significant associated with higher net daily TEI and higher intakes of saturated fat and sodium, but not sugar intake."
Researchers also concluded that pizza as a snack or from a fast-food restaurant had the greatest adverse impact on TEI and that "consumption [of pizza] should be curbed and its nutrient content improved."
