A study published in Pediatrics shows that children’s and teen’s consumption of pizza may negatively impact their health.
Since pizza is a top contributor to children’s and adolescents’ caloric intake, the researchers wanted to examine pizza consumption patterns and its impact on their energy and nutrient intake.
The researchers utilized 24-hr dietary recall data for children ages 2–11 and adolescents ages 12–19 from the 2003–2004, 2005–2006, 2007–2008, and 2009–2010 National Health and Nutrition Examination Survey. They tested changes in consumption patterns, including by race/ethnicity, income, meal occasion, and source. Individual-level fixed effects regression models estimated the impact of pizza consumption on total energy intake (TEI) and intakes of sugar, saturated fat, and sodium.
The researchers found that from 2003–2004 to 2009–2010, overall energy intake from pizza declined 25% among children (110 to 83 kcal). Among adolescents, although caloric intake from pizza among those who consumed pizza fell (801 to 624 kcal), overall pizza intake remained unchanged due to slightly higher pizza consumption prevalence. For children and adolescents, pizza intake fell at dinnertime and from fast food. For children and adolescents, respectively, pizza consumption was significantly associated with higher net daily TEI (84 kcal and 230 kcal) and higher intakes of saturated fat (3 g and 5 g) and sodium (134 mg and 484 mg) but not sugar intake, and such effects generally did not differ by sociodemographic characteristics. Pizza consumption as a snack or from fast-food restaurants had the greatest adverse impact on TEI.
The researchers concluded that the adverse dietary effects of pizza consumption found in this study suggest that its consumption should be curbed and its nutrient content improved.
