We are indeed what we eat - and what we eat remakes the world. But we are only just beginning to recognise the profound consequences of the simplest everyday food choices, both for ourselves and for the natural world. The Omnivore's Dilemma is bestselling author Michael Pollan's eye-opening exploration of the American food industry. His astonishing findings will resonate enormously for people everywhere who care about what they put on their plate.
The Omnivore's Dilemma brings a fresh perspective to the simple yet momentous question 'What shall we have for dinner?', which is overwhelming for any creature faced with a wide choice of things to eat. Anthropologists call it the 'omnivore's dilemma'. Today, as America confronts what can only be described as a national eating disorder, the omnivore's dilemma has returned with an atavistic vengeance. Dealing with each of the food chains that sustain us (industrialised food, alternative or 'organic' food and food people obtain by dint of their own hunting, gathering or gardening) Pollan follows each food chain through from the ground to sitting down to a meal, tracing the provenance of everything consumed.
The Omnivore's Dilemma is an uncompromisingly realised, eloquent, philosophical and absorbing book for anyone who thinks about where their food comes from.
