In recent years, researchers have started to understand why people love the foods they do, and that there may be a way to make snacks taste sweeter without adding any extra sugar – and it's all down to a trick that happens in the brain. This film meets a scientist who has grown a tomato that is sweeter and juicier than anything likely to be found on a supermarket shelf, and follows those hoping to become elite, professional tasters.
Episode 2 – exposes how the industrial revolution opened the floodgates for highly-processed convenience foods that became "our daily bread."

The government rates the global outbreak of a deadly flu virus as a major threat to the UK. It could happen at any time. To predict the impact of the next pandemic more accurately than ever before, new data is needed - and lots of it. Dr Hannah Fry is on the case. She sets out to recruit the nation to download the BBC Pandemic app in a ground-breaking experiment to help plan for when the next deadly virus comes to the UK. How quickly will it spread? How many could it kill? What can we do about it? The BBC Four Pandemic experiment will find out. Hannah masterminds the experiment and adopts the role of Patient Zero by walking the streets of Haslemere in Surrey to launch the outbreak. Meanwhile, emergency physician Dr Javid Abdelmoneim finds out why flu is still such a danger to society a century after Spanish flu killed up to 100 million people worldwide. He meets researchers trying to discover what makes some people more contagious than others and visits a factory that will produce vaccine when the next pandemic flu virus emerges. Armed with the information he gathers and the results of the BBC Four Pandemic experiment, Hannah and Javid make a shocking revelation.
