Every day, humans make multiple choices about what to eat. Some of those decisions will be better for our health than others - but what if we allowed a machine to decide for us? In this programme, Adam Shaw explores what would happen if we let artificial intelligence (AI) design our diets and whether that might improve our health. Adam visits a laboratory in the UK to meet AI researcher Dr James Neil, from the Centre for Nutrition Education & Lifestyle Management, whose company is developing machine-learning systems to create personalised diets. He speaks to dietician Pennie McCoy, to find out how a digital therapist called ‘Hope’ is learning to help Australians stay on track with their weight-loss goals. Dr Mariette Abrahams, dietician and CEO of Qina, a company in Portugal which offers strategic advice on the personalised nutritional market, tells Adam about the potential and the pitfalls of the new tools. And Dr Eric Topol, professor of molecular medicine and executive vice president of Scripps Research in the US, considers whether AI-driven diets will be used for a small group of people, or whether the technology could fundamentally change everyone’s approach to food.

The British "caff" - slang for café, and home of the breakfast fry up, or "full english" - is under threat. Many have closed, struggling to compete with changing tastes and the success of chains. Many of Britain’s historic caffs opened in the 1940s and 50s, run by Italian migrants. Some of these original caffs are still trading, run by second and third generation Italian families. In this programme Ruth Alexander hears stories of the famous caffs that have closed for good, and goes in search of caffs still going. She’s joined by actor Michael Simkins, who has relied on hearty caff fare during a 40-year career in the theatres of London’s West End, and meets actor and director Mark Gatiss, who is finding it increasingly hard to find a good cup of tea in the capital. Ruth visits cafes that have been operating for decades – Bar Bruno in Soho, and Dino’s Café in east London, to learn exactly what their customers love so much about the traditional British caff. Restaurant sector consultant James Hacon describes the changes seen in the hospitality industry in the last twenty years, and why caffs now face such stiff competition.

What’s the best way to produce affordable food, that’s good for the planet, and can feed us all? Is it even possible to have all three? In this programme, Grace Livingstone visits small and large farms in England and Argentina. She hears the case made for organic farming, and asks if it’s feasible for organic farms to produce enough food to feed a country. At a larger farm, she hears about why farmers rely on fertilisers and herbicides to produce large volumes of affordable food. Is it possible to farm in a way that increases biodiversity and protects the environment, whilst also remaining competitive? And what can we do as consumers to encourage and support greener farming?

Dark kitchens are the multi-block commercial units allowing virtual brands and events companies to prepare and deliver food. They’ve got a mysterious reputation, sometimes also called ghost kitchens, so The Food Chain wanted to see how they have expanded since the start of the Covid-19 pandemic. In this episode, presenter Rick Kelsey speaks to chefs who buy a place in them, and to the owners who build them. Gini and Eccie Newton run Karma Kitchen, one of the fastest growing dark kitchens in Europe. They describe how much it costs to move in, how the model has changed, and respond to the restrictions put in by local governments on the kitchens in Barcelona, France and the Netherlands. Peter Cook is someone who knows the owners of the biggest dark kitchens in the world. He has recently returned from Amsterdam where he ran the Ghost Kitchen conference, and explains how PR around the kitchens is improving as they become more open spaces. And Yousif Kurdi runs Your Kitchen across the Netherlands, including in Amsterdam. He tells Rick how working with the locals is always good for business.

Long days, unsociable hours, a hectic and pressurised workload – the working environment for health care staff is full of challenges. Maintaining a healthy diet in those conditions is tough.

Anyone who has taken a photo of their plate in a restaurant knows how hard it is to make food look good on camera. An industry is dedicated to advertising food products on TV, online and in print. What does it take to make a burger look delicious, desirable and realistic? And, most importantly, is any of the food in adverts real? In this programme, Ruth Alexander meets a food stylist, a food photographer, and a director of food commercials, who share their industry’s tips and tricks. She’s joined by stylist Claire Ferrandi Smythe in Johannesburg, South Africa, photographer Sue Atkinson in London, United Kingdom and food commercials director Steve Giralt in New York, United States, who has made a name for himself with flying food and robots.

Facing the trauma of having to abandon your home because of war or climate change, how do you find solace in food that is no longer your own? There are 10 million registered refugees in the world – probably many more - who are living this reality. In this episode, Ruth Alexander speaks to two families – one Afghan, one Ukrainian - who know what it’s like to lose their food; and to Allison Oman Lawi, deputy director of nutrition at the World Food Programme.

Humans have been accidentally feeding wild birds for millennia; any leftover food scraps to be scooped up by opportunistic, feathered friends. The deliberate feeding of birds, however - placing seeds out on a feeder in the garden, taking crumbs to a nearby park or lake – is a more recent, cultural phenomenon. In some countries, it has deep significance and one of the most popular ways humans interact with wild animals – and it’s big business. In other places, it’s practically unheard of. So, why do humans feed wild birds? In this programme, Ruth Alexander delves into the many aspects of this human-animal interaction and asks the question; who’s benefiting more, the birds or us? Ruth speaks to urban ecologist, Dr Darryl Jones, in Kuala Lumpur, Malaysia, and to keen bird feeders Dan DeBaun, in Minnesota, US; Fung Sing Wong in Singapore; Bylgja Valtýsdóttir in Reykjavík, Iceland; and Antony Tiernan, in Surrey, UK.

How do you make Michelin Star-level food, for hundreds of people, in a kitchen you just built in someone’s garden, and with no access to cooking gas? That’s just a typical scenario facing chefs in the world of high end mass catering. In this episode, we hear from John Downey, the Catering Manager at the Web Summit tech conference, on the pressures of feeding high profile figures, and VIPs who've spent $26,000 on a ticket. We also hear from Matt and Ted Lee, authors of the book Hot Box: Inside catering, the food world's riskiest business. They tell us about the stresses and often extraordinary challenges of providing high end food, at scale, at some of the USA’s most fancy weddings and galas.

Food banks have operated for decades in North America and Europe. They are generally operated as non profits, connecting food businesses that have waste with individuals, families and charities that need food. In 2006 there was just one African food bank in Egypt. A second opened in South Africa in 2009. Today there are around twenty five across the continent. In this programme we look at how African countries have adapted food banks to their needs, and hear how they address criticisms that the food bank model itself is flawed when it comes to addressing food poverty. We ask Nairobi based reporter Michael Kaloki to spend a day with Food Banking Kenya, and its founder and CEO John Gathungu. Michael visits their warehouse storage, meets small holder farmers donating surplus food, and speaks to women living in some of Nairobi’s informal settlements that rely on food donations. Ruth Alexander speaks to Elijah Addo, who founded one of Africa’s first food banks in 2015, Food for All Africa in Ghana. Gaby Kafarhire at The Global FoodBanking Network, based in Chicago in the United States, talks about the particular challenges African food banks face. And researcher Gareth Haysom at the African Centre for Cities at the University of Cape Town shares his concerns about the current system. Presented by Ruth Alexander. Produced by Beatrice Pickup.
