The anti-dementia diet
The Food Chain
Aug 6, 2025

The World Health Organisation says close to 60 million people are living with dementia; and there are 10 million new cases every year. But could what we eat help to prevent it?

Three guests who've been exploring the potential for diet to help prevent dementia tell Ruth Alexander about their findings. We hear from Professor Christy Tangney of Rush University System for Health in the United States – she co-created the MIND diet; Anne-Marie Minihane, Professor of Nutrition and Genetics or Nutrigenetics as it’s known, at Norwich Medical School at the University of East Anglia in the UK; and Dr Lizette Kuhn, a dietitian in Pretoria, South Africa.

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.
