Michael Pollan on Food

What should we eat? Jo Fidgen talks to the influential American writer Michael Pollan about what food is - and what it isn't. In an interview before an audience at the London School of Economics and Political Science he criticises the way the food industry has promoted highly-processed products delivering hefty doses of salt, sugar and fat. He believes that the plethora of accompanying health claims have left us more confused than ever about what food really is, where it has come from and its impact on our health and the environment. His solution? To cook at home. He argues that this simple change will guarantee a healthy diet and stop us relying on big food companies to feed us. It is also, he says, a profoundly political act. But is it a realistic proposition for busy working families or simply a middle-class ideology?Producer: Sally Abrahams.
