Study that took aim at ‘Joy of Cooking’ is retracted

NEW YORK (AP) — More work by a prominent food researcher is being retracted because of problems with the data, including a study that took aim at the “Joy of Cooking.”

The Annals of Internal Medicine is retracting a study that said the book’s recipes changed with updated editions to include more calories and bigger portions. It said a reanalysis by co-author Brian Wansink resulted in numbers that differed from the published version.

Wansink recently resigned from Cornell University after an investigation found he engaged in academic misconduct and several of his studies were retracted. The Annals of Internal Medicine said it subsequently reached out to Wansink, who reported the study’s conclusions were the same despite the different numbers.

Wansink previously said he believes all his research findings are supportable.
