Silly question, huh? Do you eat? But not so silly if you ask if this way: Do you eat to live or do you live to eat? The answer should be "both." You should certainly eat to live, i.e., get fuel to keep you alive from your food. But it should also be that you enjoy your food, taste your food, cook your own food, even grow a lot of your own food (or at least make friends with the people that grow it).
The idea behind a very short, simple book that everyone who eats should read is that we should do both: fuel our bodies but on healthy, "real" food, and enjoy that food, in smaller amounts of better quality so that we do not "overfuel" and continue the obesity epidemic that is engulfing the Western world, really due to our overeating and inactivity.
The book? Michael Pollan's Food Rules. It really is short, a couple of years old (2009, I believe), and consists of 64 food rules that will help you appreciate your food and eat better.
I would love it if people joined me, especially people with children, and tried to drive more than a few fast food restaurants out of business. I'm sure we could find better jobs for our unemployed than ruining the health of our overall population.
