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

More work by a prominent food researcher, including a study that took aim at the “Joy of Cooking,” has been retracted because of problems with the data. The Annals of Internal Medicine retracted 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 — “many substantially so” — from the published versions.
