A previous reviewer refered to 'Food rules' as a dumbed down re-write of Pollan's 'In defence of food', questioning why anyone would buy the adridged version. Well I bought it to pass the time on a train, and it made me laugh out loud all the way to Bristol. It's packed full of witty aphorisms that will transform your shopping habits overnight. Now, whenever I go shopping I have Pollan's 'food rules' ringing in my ears. If I have an impulse to buy junk food, I just recall that I should 'avoid food products that make health claims', or not 'eat anything your great-grandmother wouldn't recognize as food'. Even though I was already aware of many of the issues that he covers, this really does help me make better choices about my eating.
