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 trac...

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, fermente...

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 ...

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...

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 contai...

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 seed...

Mental health is a hugely complex issue with many causes. There’s no simple answer, then, when it comes to therapies for conditions like anxiety and depression. But a growing body of research is now supporting a connection between nutrition and mental health - that what you eat can have a role to play in reducing symptoms of depression and anxiety. It’s an emerging field, but dietary recommendations for patients are already being made in clinical settings. Jordan Dunbar explores the scientific e...

Climate change means that, in many parts of the world, the way we farm is no longer working. We need a larger, more diverse range of crops that perform even when the rains don’t come or, as can also be the case, when too much rain comes. Currently, just 15 crops make up 90% of our energy intake, according to the United Nations’ Food and Agriculture Organization. In this programme, we’re meeting people who are trying to develop food crops that might thrive in our changing world. Ruth Alexander vi...

Vegetable oil is one of many foods that has seen big price rises in the last year. Not only is it used for cooking and frying, but it’s also in many processed foods such as ready meals, sauces and even desserts. Ukraine and Russia represent the majority of the world’s sunflower oil production, whilst unpredictable weather, poor harvests and lack of labour have led to higher prices in palm, soybean and rape seed oil at the same time. In this programme we hear from food businesses struggling with ...

Water shortages are getting worse with climate change. In the Horn of Africa, long periods without a rainy season have created a dire situation. The World Food Programme says up to 20 million people in Kenya, Ethiopia and Somalia could be pushed into hunger by the end of the year. Somalia, which has already witnessed decades of conflict, extreme weather and disease outbreaks, is being particularly hard-hit. Experts believe droughts will become more frequent, longer and more intense, so what can ...

Good quality nutrition is key to sporting success. But while plenty of research exists on the impact of nutrition on performance, most of it has been done on male athletes. That’s despite female athletes now making up nearly 50% of participants in professional sport. In the case of female footballers, research shows they could be consuming only half the carbohydrates they need. Not eating enough – or under-fuelling – as it’s known in footballing circles – is thought to be endemic in the women’s ...

Biofuels are a way to make our cars, lorries and even planes run on renewable fuel. They’re often made from food crops. Globally 7% of cereal crops and 15% of vegetable oil crops are used to make biofuel – according to data from the Organisation for Economic Co-operation and Development (OECD) and the United Nation’s Food and Agriculture Organization (FAO). As pressure on food prices and supply chains increase, some people are questioning why we turn food into fuel. In this programme we’ll be lo...

It’s not just fauna and flora, there’s a third, much overlooked kingdom of life – fungi. Fungi are essential for plant and soil health, and therefore our own survival. It’s not just the mushrooms that we eat, in this programme we celebrate fungi in all its forms. Fungi already play important roles in our food production and medicine, scientists are now investigating fungi based solutions for environmental pollution and waste disposal.

His traumatic upbringing and subsequent search for his family and identity have informed much of his award-winning writing. In this pro...

Many chefs reach global status, with international demand for their latest book. Spare a thought for the translators, tasked with making their recipes accessible across barriers of language, culture and cuisine.

What do writers eat to stoke their creative fires? George Orwell is said to have had a penchant for plum pudding, while Agatha Christie was partial to sipping cream while at the typewriter.

Wheat is one of the most important grains worldwide: you’ll find it in bread, biscuits, pasta, sauces, sweets and more besides. Indeed, take wheat products off supermarket shelves and they would look rather bare. But recent global events – not least the war in Ukraine - have caused crop prices to soar. Ruth Alexander charts how a humble grass grown in the Fertile Crescent became a commodity traded worldwide, and she explores whether we have become too reliant on this “mega crop” for our food sup...
