Shopped - The Shocking Power of British Supermarkets

In the 1970s, British supermarkets had only 10% of the UK's grocery spend. Now they swallow up 80%, influencing how we shop, what we eat, how we spend our leisure time, how much rubbish we generate, even the very look of our physical environment.

Award-winning food writer Joanna Blythman investigates the enormous impact that these big box retailers are having on our lives. She meets the farmers who are selling food to supermarkets for less than they need to survive and the wholesalers who have been eliminated from the supply chain; she travels to suburban retail parks to meet the teenagers and part-timers who stack our shelves and reveals the hoops third world suppliers must jump through to earn supermarket contracts.

This thought-provoking, witty and sometimes chilling voyage of discovery is sure to make you think twice before you enthusiastically reach for that supermarket trolley again.
