David's writing influenced the cultural approach of the British towards food. According to the food journalist Joanna Blythman, she "performed both a cultural and gastronomic miracle in post-war Britain by introducing the nation to a vision of fresh Continental food", while the writer Rose Prince considers that David "changed for ever the way British people cook". Janet Floyd, professor of American Literature at King's College London, argues that David was not a driver of change, but came to epitomise that change. The literary historian Nicola Humble observes that "the food revolution of the post-war years would probably have happened without Elizabeth David, though in her absence it would have happened very differently".
