Food is a product of economic supply and demand, so try to figure out where the supplies are fresh, the suppliers are creative, and the demanders are informed.
Tyler Cowen’s book An Economist Gets Lunch is an enjoyable introduction to economic principles and how it relates to food. Cowen is a economics professor at George Mason, and has his own wonderful blog entitled Marginal Revolution. He has written dozens of books and has been an important voice in economics for the past decade.
In this book Tyler explores the history of food and why he believes it is in crisis, and explores how we can use basic economics to get the most out of our eating experience. Some of my favorite rules are why you should always eat on a street instead of an avenue in New York, why fighting patrons are a good sign, and how changing our supermarket experience can change our diets for the better. This book is a wonderful read, full of history, economics, and above all food. If you are looking for an introduction into economics or a guide to the mind of Tyler Cowen, this is a great place to start.
