This book explains why so many people choose to eat this way, and how it can benefit you and your body. You may or may not agree with the principles behind it, but if you are looking for an explanation of why people do it, you could do worse than to read It Starts With Food.
I waited a couple weeks to read this book after finishing The Omnivore’s Dilemma, because I figured that it would cover much of the same material. For different reasons, I wasn’t quite right and I wasn’t quite wrong.
Pollan seems to have taken The Omnivore’s Dilemma as a starting point, and then gone on to a slightly different tangent with In Defense of Food. This book moved on from talking about various food chains towards a general discussion of “food” as we know it (or don’t). Significantly shorter than the first book, In Defense of Food is an interesting analysis of what is wrong with how Americans – or anyone else eating a “Western diet” – are eating and what it is doing to our health.
Pollan has really done a good job of showing the average person what our food system has become, and what some of the alternatives are. His writing is very accessible and often humorous as well. It’s not your typical beach reading, but it worked for me, and I sped through it without even realizing how quickly it went by!
