»In Defense of Food
Michael Pollan's In Defense of Food goes to great lengths to explain why we should eat whole foods, and plenty of leafy greens.
My mother's advice, and my parents' general attitude towards food, was "Everything in moderation. Know what you are eating." This assumes that I am both rational and intelligent, which are the same assumptions that Michael Pollan makes.
For the past eight years, I have been keeping a record of what I eat. I am pretty happy about it.
