The Joy of Eating (More)

Have I ever mentioned how much I love Brian Wansink?

Yup, probably.

I love him even more today for his most recent study. Very simple, very elegant and very telling.

What did he do?

He took all 7 editions of the Joy of Cooking cookbook, identified the 18 recipes that were consistently included in all editions, and then examined the portion sizes of the resultant recipes.

What did he find?

"The average calorie increase in 18 classic American recipes has increased 35.2 percent per serving over the past 70 years. Part of this is due to the use of more caloric ingredients and part to serving sizes that showed small increases in the late 1940s and early 1960s, but showed a 33.2% increase since 1996"
Even more evidence that it's about the calories going in much more so than the calories going out.

If you want to read it, the ever lovely and always brilliant Marion Nestle is hosting it on her blog's server over here.
