Childhood obesity is one of our nation’s leading health threats. Today, nearly one in three children and youth is already overweight or obese. The obesity epidemic is clearly taking its toll, as more and more kids are developing conditions and diseases that we would normally associate with adults—like high blood pressure, elevated cholesterol, and type-2 diabetes. Some experts believe that if the childhood obesity trend continues, this current generation may become the first in American history to live shorter lives than their parents.
