Whenever there’s an article that involves an obese child, either a particular one or childhood obesity in general, many comments to the article say things like, “Lay off the fast food,” or, “The fast food chains are to blame.”
But are they really? For those who believe that McDonald’s, Burger King and KFC are responsible for the swelling numbers of obese children, ask yourself when’s the last time you took a good look at what the neighborhood grocery store sells.
A new investigation shows that the prevalence of American kids chowing down chicken nuggets, Big Macs, large orders of fries and large sugary drinks is not the cause of obesity, but a sign of the obesity times.
In other words, this is false: Lean kids go to fast food places and fill up on double cheeseburgers, curly fries and milkshakes, then get fat.
And this is true: Kids who grow up in a home where healthy eating habits, portion control and rigorous exercise are unheard of, will naturally gravitate towards double cheeseburgers, curly fries and milkshakes.
The study comes from The University of North Carolina at Chapel Hill's Gillings School of Global Public Health. The full report is in the latest The American Journal of Clinical Nutrition.
Kids’ feasting on fast food is a small part of a big picture—part of a dietary pattern that begins in the home from a very young age by the primary caretakers.
- The pattern is miniscule on fruits and vegetables.
- And it’s high on large amounts of processed food and sugary drinks.
- Unhealthy food choices are reinforced by school-offered lunches.
"This is really what is driving children's obesity," explains study leader Barry Popkin, a nutrition professor at UNC's Gillings School of Global Public Health. He emphasizes that the association between kids who eat a lot of fast food, and obesity, does not prove cause and effect.
If a child grows up on a home menu of toaster tarts and donuts for breakfast; salami and bologna sandwiches with greasy cheese puffs and soda for lunch; ice cream sandwiches and cookies for snacks; and a sodium-drenched, “chemicalized” meat and potatoes dinner from a frozen box with a side of onion rings from a frozen bag for dinner—just where do you think this individual is likely to get lunch on a Saturday afternoon when there’s no food in the house? He or she is programmed to make a beeline straight to the nearest McBurgers.
How was the study done?
Data was analyzed from the National Health and Nutrition Examination Survey (NHANES) between the years 2007 and 2010. The eating habits of over 4,400 kids ages two to 18 were evaluated and grouped:
- Non-consumers of fast food
- Low consumers (equal or less than 30 percent of calories from fast food)
- High consumers (over 30 percent of calories from fast food)
