Do school lunches plump up poor kids?

Students who eat school lunches are more likely to be become obese, a new study shows. But students who eat school breakfasts are lighter. Eating both breakfast and lunch produces the slimmest children, reports Miller-McCune Online.

Low-income children, who qualify for free meals at school, are more prone to obesity. But the researchers think the lunches themselves are encouraging weight gain.

Daniel Millimet, an economist at SMU, theorizes that school breakfasts comply with federal nutrition guidelines, or come close. At lunch, students may buy extra items that aren’t subject to nutrition guidelines because kids are spending their own money.  Schools keep the profits from desserts or snacks students pay for themselves and can use the money as they see fit.
