The venerable Joy of Cooking has kept up with America's expanding waistlines by porking out itself, reports the LA Times. A look at 18 classic recipes from seven editions found calories per serving swelled 63% in all but one recipe between 1936 and 2006. Example: beef stroganoff required 3 tablespoons of sour cream in 1997, but 1 cup in 2006—though that edition's editor maintains the cookbook has gotten healthier overall.
"It's such a tiny number of recipes. It's really a non-event," she said. "We give Americans credit," she added, "for knowing that eating a brownie is not as good as eating a plate of whole grains and vegetables." Still, says the study's co-author, "people like to plant the source of the issue on away-from-home dining"—and that may not be the source of the issue.
