The Food Chain
Mar 11, 2017

As part of the BBC wide #SoICanBreathe season, The Food Chain explores how the ways we grow and cook our food can affect how we breathe. From the indoor pollution generated by cooking, to how farming practices change the air for miles around, our food can have a big impact on how we breathe. We come full circle to find out how air pollution can get in to our food and why your lettuce might have spots.

But it's not all bad news, and we'll also visit India and Ghana to explore developments that might help us all breathe a bit more easily.

Plus, if our diet is potentially part of the problem when it comes to air pollution, could it also be part of the solution?

Can music change the way food tastes?

Music is part of the backdrop to millions of meals every day. But what if it is doing more than simply creating atmosphere?

In this episode of The Food Chain, Rumella Dasgupta explores the growing evidence that sound can shape the way we experience food and drink. From scientists studying how the brain combines hearing and taste, to chefs designing dishes around playlists, we ask whether music has become an ingredient in its own right.

Chef Gaggan Anand explains why music sits at the centre of his restaurant in Bangkok, where sound, lighting and food are carefully choreographed into a single experience. Cognitive neuroscientist Ophelia Deroy shares research showing how music can influence our perception of sweetness, bitterness and texture, and explains why flavour is far more than what happens on the tongue.

We also hear from Ola Sars, founder of the business music platform Soundtrack, whose company helps restaurants, cafés and hotels tailor the music they play. He shares research suggesting that the right soundtrack can influence customer behaviour and even affect sales.

But not everyone is convinced. Dan Keeling, co-owner of London's Noble Rot restaurants and a former music industry executive who signed artists including Coldplay and Lily Allen, explains why he has chosen not to play music in his dining rooms at all.

From silent restaurants to carefully curated playlists, from neuroscience labs to commercial dining rooms, we explore the increasingly important role sound plays in the way we eat.

The business of food tours

Food tours are becoming one of the fastest-growing parts of the travel industry, with tourists increasingly choosing to explore cities and cultures through what they eat.

In this episode, Ruth Alexander explores the global rise of guided food experiences and the people building businesses around them.

In Manchester, food tour guide Julia Fairburn takes Ruth through some of the city’s best-known food spots, explaining how successful tours combine local history, storytelling and carefully paced eating experiences designed to leave visitors with lasting memories.

Eric Wolf, founder and executive director of the World Food Travel Association in Valencia, Spain, explains how food tourism has expanded worldwide into a multi-billion-dollar industry, as travellers increasingly seek authentic and immersive culinary experiences.

We also hear from Judith von Prockel, who began creating holidays centred around food experiences more than two decades ago, long before culinary tourism became mainstream. She reflects on how attitudes towards food travel have changed and why people are increasingly planning trips around what they want to eat.

And in Malaysia, Pauline Lee from Simply Enak describes the work involved in creating memorable food tours in a growing and increasingly competitive market, where guides must balance logistics, hospitality and cultural storytelling alongside the food itself.

From hidden local gems to global tourism trends, we explore why food tours have become big business — and what travellers are really looking for when they book them.
