【科学60秒】含糖饮料毕生致力于儿童肥胖症

听力简介：

Kids from the ages of two to 19, consume about seven trillion calories in sugar-sweetened beverages per year, according to Steve Gortmaker of the Harvard School of Public Health. He spoke at the Obesity Society Annual Scientific Meeting in San Antonio on September 23rd. Seven trillion is a lot of calories in sugar-sweetened beverages.

Currently, in the U.S., about 17 percent of children and adolescents are obese—that's more than 12.5 million kids. And new research in the British Medical Journal suggests that obese children will have much higher risk factors for cardiovascular disease as adults. Even as kids, their hearts are changing shape to look like those of adults at risk for heart disease.
But the good news is that simply cutting out an average of 64 calories a day from kids' diets could start to level out the steep rise in childhood obesity. That's equivalent to less than half a can of most non-diet sodas.
