Fast Food Nation is a fascinating and very readable book. In some ways it reminds me of Upton Sinclair's The Jungle. It's not only a critique of fast food, the chemicals we are ingesting and the health problems we are facing, it is also critical of a system that allows exploitation of young, old and immigrant workers, and of the suburban sprawl that resulted from the eradication of efficient and environmentally friendly public transportation by the auto industry. The author focuses his criticism on the states of California and Colorado when in reality the same strip malls with the same chain stores and miles of fast-food clusters and suburban sprawl exist all over the US.
I have always been particular about what I eat and rarely visit fast-food restaurants, so this book has not changed my eating habits drastically. It has, however, made me a wiser consumer.
