'You are what you eat' is a phrase older than it might seem. Originating with Anthelme Brillat-Savarin, and echoed by Feuerbach ('Der Mensch ist, was er ißt.'), it was popularised in the work of the nutritionist Victor Lindlahr and the hippy movement of the 1960s. At the beginning of the twenty-first century, our culture appears fixated on the food which we eat, and the effect it has upon us. This need not be unique: Jacob Neusner has calculated that sixty-seven per cent of rabbinic legislation deals with food, its preparation and consumption.
