Fast food and diet in children

We’ve significantly reduced our eating at fast food restaurants in my family in the last year or two. A recent study in JAMA: Pediatrics affirms that was the right decision. “Fast-Food and Full-Service Restaurant Consumption Among Children and Adolescents: Effect on Energy, Beverage, and Nutrient Intake“:

Objective  To examine the effect of fast-food and full-service restaurant consumption on total energy intake, dietary indicators, and beverage consumption.

Design  Individual-level fixed-effects estimation based on 2 nonconsecutive 24-hour dietary recalls.

Setting  Nationally representative data from the 2003-2004, 2005-2006, and 2007-2008 National Health and Nutrition Examination Survey.

Participants  Children aged 2 to 11 years (n = 4717) and adolescents aged 12 to 19 years (n = 4699).

Main Outcome Measures  Daily total energy intake in kilocalories; intake of grams of sugar, total fat, saturated fat, and protein and milligrams of sodium; and total grams of sugar-sweetened beverages, regular soda, and milk consumed.

Results  Fast-food and full-service restaurant consumption, respectively, was associated with a net increase in daily total energy intake of 126.29 kcal and 160.49 kcal for children and 309.53 kcal and 267.30 kcal for adolescents and with higher intake of regular soda (73.77 g and 88.28 g for children and 163.67 g and 107.25 g for adolescents) and sugar-sweetened beverages generally. Fast-food consumption increased intake of total fat (7.03-14.36 g), saturated fat (1.99-4.64 g), and sugar (5.71-16.24 g) for both age groups and sodium (396.28 mg) and protein (7.94 g) for adolescents. Full-service restaurant consumption was associated with increases in all nutrients examined. Additional key findings were (1) adverse effects on diet were larger for lower-income children and adolescents and (2) among adolescents, increased soda intake was twice as large when fast food was consumed away from home than at home.

Eating at fast food restaurants is associated with significantly increased caloric intake, as well as increases in fat, saturated fat, and sugar. Plus, adolescents double their soda intake at fast food restaurants.

This isn’t surprising, but the magnitude is troubling.
