You'd be amazed at how much Russian Jews in Chicago eat!

In the early 1900s, the government began to learn how to determine fat and protein amounts in food and the calorie was invented. A publication from the Dept. of Agriculture entitled "Investigations on the Nutrition of Man" included the results of a survey of various groups of people. While the statistics on how much each group eats and what sort of things they eat amazingly corresponds to the sort of food that would probably have been available to them (in terms of grain vs. meat), the groups they were separated into are far more interesting. I figure it'll just be easiest to give you the complete list- the amusing bits sort of jump out at you anyway:
