From Garrison Keilor's Writer's Almanac:
"There's a diet named after Nobel laureate economist George Stigler. The Stigler Diet is actually a mathematical model for the cost of subsistence eating — a linear programming problem on how to get the most nutritional bang for your buck. Specifically, Stigler's math problem was this: Say you have a man who weighs 154 pounds. Out of 77 foods commonly available, how much of each one should be eaten daily so that the man gets the right amount of nine essential nutrients — at the cheapest cost? The nutrients Stigler took into consideration: calories, protein, iron, and some vitamins.
The solution to the optimization problem: In one year, that man should consume 370 pounds of wheat flour, 57 cans of evaporated milk, 285 pounds of dried navy beans, 23 pounds of spinach, and 111 pounds of cabbage. In 1939, dollars, this would cost about 11 cents a day. Today, it'd be close to $1.75 per day. Stigler was subjected to a barrage of ridicule for suggesting this dull and bland diet, and he tried to remind people that it was just a mathematical model. He issued a statement: 'No one recommends these diets for anyone, let alone everyone.' "
It does make me think I could live on a lot less than I do....
