Dr. Brian Wansink, of the Cornell Food and Brand Lab, is the author of a new research study on the Joy of Cooking.
The study involved comparing 18 recipes that have survived the various editions of Joy. 1936, 1946, 1951, 1963, 1975, 1997 and 2006 were the editions used in the study.
Researchers documented the serving size and caloric in each version of the 18 recipes. They found that 17 of the recipes underwent changes that mirrored America’s obestiy epidemic.
Dr. Wasink comments, “What we think is a normal serving size has increased dramatically over the last 70 years â€¦ as has what we demand in terms of fat and sugar in a recipe.â€
“According to the study, in 1936, the average number of calories in each recipe was 261. The most recent recipes average 384 calories, an increase of 60 percent. If you were to compare just the recipe for sugar cookies, you would find an 142 percent increase in the number of calories from the 1936 recipe to today’s recipe.
