The Food Chain

There are trillions of bacteria living in our guts and there's growing evidence that they can have a major impact on our mental well-being. So could we soon see a food supplement that can treat depression?

The science behind this so-called gut-brain axis and whether we can manipulate it isn't yet conclusive, but there are plenty of believers. We speak to a woman who says her irritable bowel syndrome and anxiety disappeared after she started taking kefir, a fermented milk drink. She was so convinced by its impact that she now runs a south London business making and selling it.

There are already food supplements out there targeting anxiety and depression, but are they getting ahead of the science? We speak to one of the major probiotics manufacturers and hear from a leading scientist who says unproven product claims could be dangerous for mental health patients and that they shouldn't be seen as a silver bullet.

Plus, how human are we really? We find out just how many strings our microbes are pulling.

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.
