Soft Drinks Require a Hard
A recent summary of research by a school nurse into obesity
in American adolescents led to a not too surprising conclusion: Soft drinks are
accounting for a significant protion of the calorie intake in an average teen's
I say not surprising because soft drink companies have to
be one of the most rampant advertisers in our marketplace. The ongoing war
between the two "Big Ones" alone has saturated our media environments with
images of athletes, blonde bombshells, and every other demographic imaginable
guzzling down frost encrusted cans and bottles of the sugary beverages.
But the feature article by Susan Harrington, RN in the
February 2008 edition of The Journal of School Nursing offers a chilling
view of what having sodas become an integral part of a teen's diet has done. To
begin, one research paper she quotes estimates that one soft drink per day will
produce a 110-pound increase in body mass over a period of ten years.
Other research offers interesting insight as to why, in
this world of reduced fat foods, adolescent obesity is still on the rise? Two
studies looked at groups of teens that were on fat controlled diets versus
sugar-controlled diets. It turns out those who were able to eat whenever they
wanted, but had to choose from low sugar (or, in technical terms, low-glycemic
index or GI) foods lost weight while those who were on fat controlled diets
actually saw an increase in insulin resistance -- meaning sugar was a greater
contributor to maintaining obesity than was fat consumption. The study also
noted that teens tend to adhere better to a diet that allows them to eat when
Additional surveys discovered that high sugar drinks were
replacing young people's tendency to choose milk, resulting in a reduction of
calcium and zinc in their diets. As well, drinks with sugar tend to stimulate
additional hunger responses, resulting in the consumption of additional food.
Conversely, drinks like milk tend to contribute to the feeling of being full and
satisfied after a meal.
Harrington notes that in 2001 over 60% of U.S. middle and
high schools reported having soft drink vending machines. In 2002, an estimated
240 U.S. school districts had entered into exclusive "pouring rights" --
contracts with soft drink companies. These agreements kick back cash and
incentives to schools in return for allowing the soda merchants to sell drinks
in hallways and cafeterias, along with advertising on school properties. Some of
these contracts even result in revenue being directly linked to the amount of
drinks sold in the school.
At that time, 76% of principals surveyed claimed parents
were not concerned with (quoting the survey question) "commercial companies
going into schools and seducing their children into buying specific products for
the economic improvement of the schools."
Lest you think schools are the sole source of children
finding super sweet drinks, it turns out most of the consumption (according to
one of the quoted studies) happens at home. In an attempt to see what would
happen with intervention, in 2006 researchers began delivering alternative low
caloric beverage choices to the homes of a portion of 103 obese adolescents.
Those who were in the group receiving the alternative drinks saw a "significant
beneficial effect on body weight."
The good news is the studies offer methods parents and
teachers can employ to combat the obesity trend. Educating young people on good
food choices is somewhat effective, although teens are often resistant to adults
providing dietary directions. In my own work, I have discovered teens often
possess a cynical view of advertising, and this perspective can be leveraged to
help them come to their own conclusions about the value of the products they are
being sold, and how they are affecting their bodies. Harrington also makes a
point of showing how school nurses can play a pivotal role in this process.
In their defense, the beverage industries are also stepping
up to help, and have adopted School Beverage Guidelines that target the
reduction of calories in drinks sold in schools at all levels. The American
Beverage Association claims changes are already taking place, with declines in
deliveries of carbonated sugar drinks to schools and increases in water, diet
drinks and pure juice drinks.
It's a good start, but more needs to be done. Parents, the
next time a frosty covered soda appears on your television screen, take the
opportunity to discuss options for other drinks and put the soda back into the
"occasional treat" category where it belongs.
