Do Sugar-Sweetened Beverages cause Obesity?

In today’s society obesity has emerged as a major health problem worldwide and the implications of this epidemic are extensive. Research by Malik, Popkin, Bray, Després, and Hu (2010) indicate that being overweight or obese are important risk factors for type 2 diabetes mellitus (T2DM), cardiovascular disease, cancer, and premature death. In recent years, the link between sugar-sweetened beverage (SSB) consumption and obesity is becoming clearer.  In the past 30 years in the United States, the intake of SSBs, including soft drinks, fruit drinks, energy drinks, and vitamin water drinks, has increased 3-fold (Malik et al., 2010). The contribution of SSBs to weight gain is thought to be from their high added-sugar content, low satiety, and potential incomplete compensation for total energy.  All of these factors lead to increased energy intake. Furthermore, Malik et al. (2010) indicated that SSBs may increase T2DM and cardiovascular disease independently of obesity. This is because SSBs often contain high amounts of rapidly absorbable carbohydrates such as different forms of sugar and high-fructose corn syrup. Large quantities of these sugars contribute to a high dietary glycemic load, which leads to inflammation, insulin resistance, and impaired β-cell function.  Specifically, the research also found that fructose may also increase blood pressure and promote the accumulation of visceral adiposity, dyslipidemia, and ectopic fat deposition (Malik et al.,2010)

Based on this information about SSBs, the pressing issue of childhood obesity has immense consequences for today’s youth. According to Malik et al. (2010), not only is there a positive correlation between SSB intake and weight gain in children and adolescents, but it has also been shown that increased SSB intake during childhood predicted weight gain into adulthood. The prevalence of SSBs consumption was observed at Monroe Intermediate School District Educational Center.  The Education Center provides special education programs to a variety of children with different cognitive and physical disabilities. Specifically, these students are supplied diet coke to take their medications instead of water.  Many students refuse to drink anything but soda or juice and it was shockingly rare to see any children consuming water. An article published in The New York Times on August 5, 2013 discussed a study linking SSB consumption and higher body mass index scores in 2- to 5-year-olds (Dell’antonia, 2013). Additionally, the article identified further issues including the association between higher body mass index and television watching and failing to drink milk.

In order to combat the effects of SSBs and obesity in today’s society and especially in children and adolescents, it is important to advocate for alternatives to sugar.  Briefel, Wilson, Cabili, and Hedley Dodd(2013) stated that the daily energy intake of school-aged children has increased by more than 200 extra calories due to the sugar from sweetened beverages.  Also, Briefel et al. (2013) emphasized that even the empty calories from added sugars in flavored milks need to be monitored in overweight elementary and middle school students.  Reducing consumption of SSBs is pertinent to work towards the prevention of obesity.  In order to begin improving the quality of children’s beverage consumption, it is necessary to research about children’s home food environment and to teach effective behavioral approaches to guide healthy choices (Briefel et al., 2013). As healthcare professionals, teachers, or adults, how can we help children make healthy beverage choices?

  1. I could not agree more about eradicating SSBs due to the positive correlation with DM, heart disease, and obesity. Not only do healthcare professionals, adults, and teachers need to help prevent the surge of SSBs in children (and in adults, too), but so do organizations. Just recently, University of Michigan Health System and medical school stopped selling sugary drinks in cafeteria and vending machines. The story was featured on Channel 4 WDIV. See the attached article:

  2. Apart from the link between SSBs and obesity that Kimmy discussed, a new study found that soft drinks and sugar may also affect kidney function (The Indian Express, 2013). Drinking 2 SSB a day is linked with increased protein in the urine. This study also found that in rats, sugar intake increased the body's sensitivity to angiotensin II leading to salt re-absorption. This may also help explain the link to diabetes, obesity, and hypertension. This serves as further proof that decreasing or eliminating SSBs in childhood can help protect a child's future health.

  3. I have heard much discussion around UMHS about the roll-out of no sugary drinks. Some of the adults don't seem to grasp the concept that children learn by observing and healthy behavior should be modeled for children, not just expressed verbally.
