What is 'natural' food and is it better for us? We explore the language of food labelling. Does a product bearing the word 'natural' on its label make you more likely to buy it? Or, is describing food as 'natural' just a marketing trick? We hear from a cattle farmer in the US state of Vermont who stopped using growth hormones on his herd so that the meat can be sold as 'natural'. Consumer psychologist Kit Yarrow, professor emeritus at Goldengate University in the US, explains how companies market "natural" food to us.Are some supermarkets misleading their consumers with the way they are presenting their food? Journalist Tom Levitt from The Guardian tells Manuela Saragosa why some packaging may not tell the whole story. And we hear how the mislabelling of food in China can provide rich pickings for professional label readers. With more and more products declaring their 'pure' origins, David Jago, director of Global Insight and Innovation at the market intelligence company Mintel, outlines the size of the market. Should the word 'natural' be more closely defined? We ask Daniel Fabricant, CEO of the Natural Products Association in the US and a former FDA official.Also, Manuela asks whether a diet of completely unprocessed natural food could actually be healthier for our bodies. Nutritionist Dimple Thakrar from Fresh Nutrition tells us why some processing could add to a healthy diet. And lawyer Kun Hoe describes how some professional label readers in China can benefit from mistakes in packaging.(Photo: Shoppers in China's Anhui province. Credit: STR/AFP/Getty Images)
