Obesity is one of the biggest threats to child health. Genetics, decreases in physical activity, increases in television watching, and consumption of fast food are factors that have led to an increase of childhood obesity in the United States. Excessive consumption of sugar sweetened drinks may also be a key factor. A commentary in the May issue of The Journal of Pediatrics reviews prior research to provide perspective about the role of soft drinks in childhood obesity.
Robert Murray, MD and colleagues from Ohio State University, University of Vermont, and University of California San Diego reviewed articles, press releases, statements, and editorials from researchers and from representatives in the soft drink industry. Although no single factor can be cited as the sole cause, many of the articles showed a correlation between soft drink consumption and the risk of childhood obesity.
Dr. Murray points out that "the typical teen consumes approximately two-12 ounce cans of soft drinks per day, containing 300 calories and 20 teaspoons of sugar." Although current guidelines recommend a limit of 10% of daily calories from added sugars, they actually account for 18-20% of childrens daily calories. Because even small amounts of sweetened drinks at home or at school can add up, soft drinks and sweetened fruit drinks account for 43% of these total added sugars. American children consume one-third of their daily calories from nutrient-poor, energy-dense snack foods, which makes nutritional deficiencies another area of concern. Children seem to be choosing soft drinks or sweetened fruit drinks instead of milk, which can decrease their levels of protein, calcium, zinc, and vitamins A and C. The American Academy of Pediatrics Committee on School Health has stated that the consumption of soft drinks in schools can lead to obesity. Despite this, one study showed that out of 523 school districts, 50% had a contract with a soft drink company; two-thirds of those districts were given incentives by the soft drink company, and nearly 80% received a percentage of the soft drink sales. Dr. Murray recommends that schools should "strengthen existing programs such as the school breakfast program, the national school lunch program, classroom nutrition instruction, daily physical fitness instruction, intramural sports, and after-school programs," instead of setting up contracts and marketing with soft drink companies.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
