Food research articles retracted by leading medical journal

CHICAGO (AP) — A leading medical journal has retracted six articles on food research by a Cornell University marketing professor.

Papers were retracted Wednesday after the university said it didn’t have access to the original data to verify the results.

The research includes a 2005 study that said people eat more when served food in large bowls, and a 2013 article that said hungry grocery shoppers buy foods with more calories but not more food. The articles by Professor Brian Wansink appeared in journals of the JAMA Network, including the Journal of the American Medical Association.

Wansink says he’s proud of the papers and confident they’ll be replicated by other groups.

A spokesman for Cornell said the university would release a statement about its own review on Friday.
