The Food Chain

Protein is a health and fitness buzzword – plastered on packaging, prioritised in diets and praised by fitness influencers. But is our preoccupation with protein overshadowing another nutritional essential – fibre? Ruth Alexander explores the science, and marketing, behind protein’s popularity with expert guests Dr Emma Beckett, a food and nutrition scientist and communicator in Australia, and author of You Are More Than What You Eat; physician and social media creator Dr Karan Rajan, who is the author of This Book May Save Your Life; Scott Dicker from SPINS market research company in Chicago; Paul Kita, deputy editor of Men’s Health Magazine in the US.

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.
