People buy 90 per cent of their food from supermarkets, giving the stores a huge influence on customers' lives. Gregg Wallace looks at how some of Britain's biggest retailers gear up for Christmas, when food sales increase by 36 per cent. He sees what it takes to deliver millions of turkeys, finds out about the science that goes into making Brussels sprouts tasty and discovers how the supermarkets make sure they have stocked enough of people's favourite drinks.
