Food is one of life's great joys. So why has eating become such a source of anxiety and confusion? Bee Wilson shows that in two generations the world has undergone a massive shift from traditional, limited diets to more globalized ways of eating, from bubble tea to quinoa, from Soylent to meal kits. Paradoxically, our diets are getting healthier and less healthy at the same time. With wit and wisdom, Wilson explores our culinary landscape in such chapters as "The Enigma of the Protein Bar," "Now Comes Quinoa," "The Death of the Lunch Hour," and "The Mythical Banana Kingdom of Iceland."
