Why has childhood obesity and type 2 diabetes in kids become so common over the past 10 years in the u.s?

Poor food, sugar bev: There is a direct correlation with the increase in childhood obesity and sugary beverage consumption. The facts regarding this are astounding. In addition, children are victimized by advertising in their tv programming that predisposes them towards horrible foods (sugar cereals) that disguise themselves as healthy (i.e., whole grain etc). Portion sizes have grown while nutrition is depleted.

We aren't sure: The answer is probably not as simple as every one is eating too much and exercising too little, although these things can contribute heavily. Not all patients with t2dm are obese, although many are. Unknown environmental contributors (pcb's? Hormones in food?..) may play a role.
