The Food Chain

Samuel Ikua is championing urban farming in his city, Nairobi in Kenya. Samuel undertook an urban farming course in 2015, run by a local NGO called the Mazingira Institute. Seven years later Samuel is the project coordinator at the institute, training other members of his community in urban farming skills. In this programme Ruth Alexander hears about the challenges Samuel faces, a lack of space and land, and local attitudes to farming in a big city. Samuel’s commitment to food security in Nairobi saw him chosen by a panel of international judges as the winner of The Food Chain Global Youth Champion Award 2022.

Food behind bars is not intended to be a Michelin-starred affair. But prison food reformers claim some of it is so bad that it could be hampering the rehabilitation of inmates. Nutritious and tasty meals, they argue, can improve the physical and mental health of those serving prison sentences and therefore cut reoffending rates. And food skills; like cookery, baking and farming, could help in the rehabilitation process too. In this programme, Ruth Alexander speaks to three people with detailed knowledge of food in prison environments to explore the good, the bad and the ugly of eating in incarceration, and the power of food. Ruth speaks to Alex Busansky, head of research centre Impact Justice; Lucy Vincent, founder of the charity Food Behind Bars; and ex-offender, now consultant on prison reform, Sophie Barton-Hawkins.

How does sound influence the way we eat, drink and taste? We discover our hearing makes a bigger contribution to flavour than we think. Mike Johnson explores the concept of 'sonic seasoning' - the idea that different sounds can accentuate the sweetness, bitterness or spiciness of food. Chef Jozef Youssef, founder of the multi-sensory dining experience Kitchen Theory, serves up a musical food experiment, and Charles Spence, professor of experimental psychology at Oxford University, gives his track recommendations.From the crunch of a crisp to the background music in a restaurant, we examine the science that links our ears and taste buds with a journey into the brain flavour network.Plus, how the food and drink industry is cashing in on the selling power of sound - we speak to branding expert Martin Lindstrom about his painstaking work with some of the world's biggest fizzy drink manufacturers.Also, could the concept of sonic seasoning be used in the battle against diabetes and obesity?(Photo: Apple and headphones.

In this programme we explore the realities of island diets. Ruth Alexander hears how diets are changing, and what this means for population health. Indigenous diets were limited to what grew in the native soil or could be raised or caught in the limited space available. Today imported, often processed foods are becoming increasingly popular. We start in the Faroe Islands, in the North Atlantic Ocean between Iceland and the United Kingdom. Traditionally the Faroese diet is protein heavy, fermented wind dried lamb is a staple and the poor soil makes growing a wide range of vegetables challenging. Reporter Tim Ecott travelled to the Faroe Islands for this programme to report on how diets there have changed. We then look South to the Pacific Islands, starting with the coral atoll nation of Kiribati. The coral ground makes it difficult to grow food to supplement the diet of seafood. Ruth speaks to dietitian and public health nutritionist Dr Libby Swanepoel from the Australian Centre for Pacific Islands Research based at the University of the Sunshine Coast, Libby makes the case for seaweed cultivation to supplement diets and incomes. In contrast the nation of Fiji in the Pacific Ocean has volcanic soils, and an array of fruit and vegetables can be grown. Despite this communities have increasingly turned to imported processed foods, contributing to a health crisis. Sashi Kiran, founder of FRIEND Fiji - the Foundation for Rural Integrated Enterprises and Development – talks about how this can be addressed. Presented by Ruth Alexander.

All-you-can-eat restaurants are popular, as are high-end buffets at big weddings and posh hotels. But what’s the trick to making money out of them, and what happens to the leftovers? Ruth Alexander finds out the tricks of the trade with John Wood of catering software company Kitchen Cut, Sandeep Sreedharan of Goa, and Michael Brown of Cosmo, in Manchester, UK.

Today’s Sephardic Jewish community has its roots in Spain and Portugal. The Hispanic Jews lived for many centuries in those countries but faced increasing persecution in the 13th and 15th Centuries. Many were forced to convert to Christianity, but some secretly continued their Jewish faith and practices. In 1478, the Spanish Christian royalty created the Inquisition, a series of trials aimed at identifying those who had not converted. Food and methods of food preparation are frequently cited as evidence against Jewish people in Spanish Inquisition trial records. Ultimately the Jews were expelled from Spain and they fled to other countries. This was the beginning of a diaspora which carried its Spanish food traditions with it. Ruth Alexander meets three women who have published Sephardic cookbooks reflecting on this turbulent past. Hélène Jawhara Piñer is a French historian and chef, she studied Spanish Inquisition trial records for her book Sephardi: Cooking the History. Stella Hanan Cohen lives in Zimbabwe; in her book Stella’s Sephardic Table she records the cuisine of the Sephardic community that settled on the island of Rhodes, now part of Greece. Genie Milgrom was born in Cuba and lives in Florida in the United States, she found handwritten recipes that had been passed down by generations of women in her family, which she published as ‘The Recipes of My 15 Grandmothers’.

What are the nutritional challenges, and the highs and lows of food in space? As NASA looks at creating a lunar habitat, and even launching a mission to Mars, how can the right food be prepared and transported to keep astronauts both healthy, and happy? Marie Keyworth speaks to veteran astronaut Nicole Stott, and NASA’s top nutrition expert Scott Smith, who leads the Nutritional Biochemistry Laboratory at NASA’s Johnson Space Center, in Houston, Texas. Marie finds out what it’s really like to eat in zero gravity, and how nutrition is being used to counteract the extreme health impacts of spaceflight on the human body. Studying astronaut diets in space might even help our understanding of nutrition here on earth. Presented by Marie Keyworth. Produced by Sarah Treanor.(Image: astronaut in space holding a burger.

Global food prices reached record highs this year due to a combination of factors including the war in Ukraine, rising energy prices and poor harvests. Prices are now falling, but remain higher than last year. In this programme Ruth Alexander talks to three farmers on three different continents, to discuss if they’re profiting from these higher prices, the impact of higher costs, and whether farmers ultimately have any influence over the price we pay in the shops. Ruth is joined by Anne Gitau, a poultry farmer in Nairobi Kenya; John Kelly, a dairy farmer in Country Wicklow Ireland; and Bob Lowe, a beef and barley farmer in Alberta, Canada. The BBC’s Global Trade Correspondent Dharshini David joins the discussion to explain what is happening in global feed and fertiliser markets. Presented by Ruth Alexander. Produced by Beatrice Pickup.

We may be living in a disposable age, but many of us probably own at least one hand-me-down pot, pan or kitchen utensil. They can be heavy and cumbersome to use but promise quality and reliability - a steadfast companion in the kitchen. They hold sentimental value too: memories of home, of loved ones who have passed, and ancestral traditions. In this programme, Ruth Alexander explores the history of some of these pieces, the sentimental and practical value to their owners, and the stories contained within. She speaks to three amateur cooks: Steven Hopper from Mississippi in the US, Alice Smith from South Wales in the UK, and Amrita Amesur in Hyderabad, India.

Today’s seed industry is dominated by a handful of companies. Approximately 60% of the market is controlled by just four companies. Many of the seeds planted by farmers are controlled by international property rights or patents, that limit how they can be used. Court cases have centred around whether farmers have the right to save and reuse seeds for future harvests. In this programme we’ll chart the history of the seed industry, from the 19th century, when the United States government sent seeds in the post to farmers for free, to the growth of genetics in the 20th century which set the foundations for today’s market. Ruth Alexander is joined by Courtney Fullilove, Associate Professor of History at Wesleyan University in Connecticut, United States, and author of ‘Profit of the Earth: the global seeds of American Agriculture'; Frank Terhorst, Head of Strategy and Sustainability in the Crop Sciences Division of Bayer Global, the biggest seed company in the world; Michael Fakhri, the United Nation’s Special Rapporteur on the right to food, and Professor at the Oregon University School of Law in the United States; and Dr Tamene Yohannes, from the Ethiopian Biodiversity Institute in Ethiopia, which works with community seed banks around the country.
