This book actually had quite an impact on my food choices. I was surprisingly ignorant of "where my food comes from" in relation to agribusiness, local and organic foods, supermarket sources, etc. The book served as a really good overview of how to go about being a responsible consumer of food and led me to further exlore my food choices. Really interesting. I think Jane Goodall is an amazing woman, though not the biggest authority on food or farming. She introduces a number of experts on the subject and provides suggestions for further interest.
And, as a bonus, I now eat mostly (though not exclusively) vegetarian, whole grains, and local, seasonal produce and I feel better and I've lost weight. Plus, food tastes better.
