Simon Rimmer explores how food is transforming our lifestyle, with a quarter of us regularly eating out for breakfast. Sophie Morgan asks whether the nation's favourite drink, tea, could challenge the booming coffee sales on the high street. Simon visits the award-winning packaging company whose innovations have allowed high street chains to offer delivery to our homes for the first time. Sophie investigates what restaurants are doing to cut salt levels, as we're still consuming a third more than we should, and reveals the surprising amounts of salt in some desserts. Plus: the psychological tricks to make customers spend more in restaurants, from lighting to aroma and even seat padding.
