I spend a lot of time writing about food — notably, bad food, on Yuckylicious. A good deal of Yuckylicious posts however, feature foods from really old cookbooks — that is to say, from before the agri-industrial industries replaced much of our naturally-occuring food with processed food. Sometimes the dishes themselves sound horrid to our modern palates, but the science behind them, and the nutrients in them, were sound.
As such, they often echo Michael Pollan's Food Rules: Eat food. Mostly greens. Not too much.
Pollan is a loud and articulate voice for food sense, and this animation of his 2010 RSA Keynote speech is eloquent too.
