Failures of the free market: food

One of the nice things about the USA is that every food package has a handy table on the back listing the proportions of various nutrients it contains. (It looks like the one on the front page of my web site.) This makes it very easy to look at two cans of soup, and say “Jeez, this one is 34% of my recommended sodium intake for the day, and 20% of my recommended fat… but this one is only 10% sodium and 2% fat.
