As the credit crunch bites, thousands of families are cutting back by swapping expensive premium-range food for cheaper budget lines, but at what cost? In this Dispatches investigation, part of Channel 4’s The Great British Food Fight season, food critic and author Jay Rayner examines what goes into these budget products and asks why, too often, low cost means low quality.

Dispatches also follows two families in Leeds as they try to reduce their weekly shopping bill: one by choosing supermarket value brands and the other by shopping at local independent stores.
