NEW YORK —More work by a prominent food researcher, including a study that took aim at the “Joy of Cooking,” has been retracted because of problems with the data.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