Narrator: This is Science Today. A nationwide study conducted by Mayo Clinic scientists found that arm fractures - particularly in adolescent boys - have risen dramatically in the last three decades. Part of the problem is that children are not getting enough calcium in their diets to produce strong bones. Instead, studies have found that they're consuming too many soft drinks. Joanne Ikeda, a nutrition expert at the University of California, Berkeley, says this can lead to a whole host of health problems.
Ikeda: In the long term, we are going to pay more money out in health care costs than we're going to gain in terms of the profits from selling this stuff to children. I think we need to look at this over a period of years - yes, a school district might make a few hundred thousand dollars over a period of years, but society will be spending millions of dollars on the health problems that are going to result from poor quality dietary intake.
