Food for ingestion and digestion

I was talking with a friend the other day who, surprisingly to me, told me she was reading The Omnivore's Dilemma. That made me sooo happy! Now, I had read that book a few months ago, but I must say: it's brilliant. I believe I told my friend that it seemed to encapsulate most everything that I felt about food, to be honest. So, this is a plug for a brilliant book - go and read it! And, if you don't want to buy it or steal it, then ask real nicely, and I'll lend it to you! This would be particularly helpful if you've been scratching your head trying to figure out what the heck I'm usually ranting about on the issues of food and agriculture...
