Kids paying cash for lunch eat healthier, Cornell study shows

The more current the currency, the better kids eat, according to a study that looked at how payment methods in public school lunch systems affect food choices. The study, by Cornell researchers funded with a government grant, looked at two types of payment methods in public school cafeterias, those that accept only pre-loaded debit cards and those that accept cash or debit card.

Study fails to find link between obesity and junk food sold at schools

Researchers looking for a link between the availability of junk food at school and high obesity rates among 5th and 8th graders, could not find evidence that the children were influenced by the wealth of chips, candy and soda sold at school.

“We were really surprised by that result and, in fact, we held back from publishing our study for roughly two years because we kept looking for a connection that just wasn’t there,” said Jennifer Van Hook, a Professor of Sociology and Demography at Pennsylvania State University and lead author of the study, which appears in the January issue of Sociology of Education.
