The risk takers Feb 19, 2026

Show notes

Every food company starts with a gamble - and not all of them pay off. In this episode Ruth Alexander speaks to business owners about the risks they’ve taken to get where they are today, from financial leaps to personal sacrifices, and the painful decisions that have shaped their journeys.

Ruth hears from Kim Kiarie, chef-owner of Five Senses Nairobi in Kenya, about building a high-end restaurant in a challenging market. Adonis Norouznia, who runs Nomas Gastrobar in Macclesfield in North-West England, on the risks of deciding to serve meat at his vegan restaurant, and Keith Bearden, CEO and co-owner of Alta Eco Foods in Houston, Texas, about scaling a food business in a competitive industry.

They describe the compromises that cost them dearly, the moments they wondered whether it was all worth it, and what kept them going. Produced by Izzy Greenfield

How to write a recipe Feb 12, 2026

Show notes

We all have recipes we turn to again and again, perhaps from the stained pages of our favourite cookbooks, or handed down through families. But have you ever wondered about the work that’s gone into writing that set of instructions? In this edition of The Food Chain, Ruth Alexander looks at the art and science of recipe writing.

How does a cook turn what is often an instinctive and creative process into a list of instructions anyone can follow? How much detail is too much, and what are the essential elements no recipe is complete without? Ruth talks to a well-known cook who describes her love-hate relationship with recipe writing and a cookbook editor reveals how she’s built recipes from chefs’ doodles or even notes scrawled on a napkin. Find out what it’s like to work in the world of recipe testing and how the art of writing recipes has changed over hundreds of years.

Can you learn to love the foods you hate? Feb 05, 2026

Show notes

Most of us have foods we refuse to eat - think coriander, or maybe olives. But where do those strong dislikes come from, and is it possible to change them?

In this episode of The Food Chain, Ruth Alexander sets out to find out whether you really can learn to love the foods you hate. From first encounters that go wrong to memories that linger, she explores why food preferences can feel so fixed, and whether anything might help shift them.

Ruth speaks to neuroscientist Dr Dana Small, professor and Canada Excellence Research Chair at McGill University, about what’s happening in the brain and body when we eat, and how unconscious reward signals shape what we come to like or avoid.

She also hears from psychologist Dr Rachel Herz, an expert on the science of smell and author of Why We Eat What We Eat, about the powerful role odour, memory and emotion play in food dislike, often before we’re even aware of it.

And registered dietitian Clare Thornton-Wood shares practical, low-pressure techniques used with both children and adults to build tolerance - and sometimes even enjoyment - for foods they can’t stand.

Fermented foods: A beginner's guide Jan 29, 2026

Show notes

Fermented foods are fashionable – kimchi, kefir, kombucha – they're all having a moment, many thousands of years on from where they were first produced. But how much do you know about how they're made? Do you know your SCOBY from your kefir grain?

In this episode, fermenting novice Ruth Alexander goes on a quest to find out more about this ancient way of preserving food; how to do it yourself, why you might want to, and what it's doing for our guts.

Follow along as she experiments with making her own kefir, and talks to fermentation guru Sandor Katz about how to get started and whether there's anything that can't be fermented.

Scientist Professor Gabriel Vinderola explains what's known about the microbes behind it all and how they affect our health while Kheedim Oh and his mum Myung Oh talk about how they've brought the family recipe for kimchi to a US audience via their business, Mama O's Kimchi. (Kimchi on pizza anyone?)

And with the help of Adam Goldwater from UK based Loving Foods Fermented, Ruth discovers how kombucha is made, and the alien like SCOBY powering the process.

Produced by Lexy O'Connor. The sound engineer was Andrew Mills.

Dinner unboxed Jan 22, 2026

Show notes

Meal kits have become a familiar part of food shopping in many countries, offering pre-portioned ingredients and recipes delivered to the door. But how widespread are they, and what do they reveal about how people are eating today?

Ruth Alexander hears from Philip Doran, CEO of HelloFresh UK and Ireland, and Sarah Hewitt, CEO of South African meal kit company UCOOK, about how these services operate in very different markets.

She also speaks to Dr Rebecca Bennett, a food systems researcher, about what meal kits say about changing cooking habits and online food platforms, and to market analyst Nandini Roy on how big the global meal kit industry is and where future growth may come from.

Should we all eat the Mediterranean way? Jan 15, 2026

Show notes

The Mediterranean diet is rich in vegetables, pulses and olive oil and traditionally includes small amounts of fish and very little red meat. Thousands of studies back its health benefits. In fact, it's considered to be one of the most widely researched diets in the world. But why has this way of eating come to prominence over others?

Marta Guasch-Ferre from the University of Copenhagen, Denmark explains what the Mediterranean diet is and how her Spanish roots have informed her work.

Professor Sarah Tracy from the University of Oklahoma tells the story of the diet's roots, popularised by American scientist Ancel Keys in the 1950's.

And Ruth asks, if this way of eating isn't familiar in your culture, can you still make use of the Mediterranean diet's principles to improve your health? Singapore based cardiologist Professor Huang Zijuan has been looking at the science behind Asian inspired food swaps that could offer the same health benefits.

Plus public health expert Professor Pekka Puska explains how he used the work of Ancel Keys in the 1970's to help transform the life expectancy of Finnish men. He co-led the now world famous North Karelia project, after Keys' research revealed how the region in eastern Finland had the highest rates of blood cholesterol in the world.

Food is at the centre of family life – on ordinary days, in the everyday rush, during the dramas, and the quieter moments too.

From the first meal taken by a foster child in an unfamiliar home to the couple cooking together for the first time in their lives after a dementia diagnosis, these stories show how food has the capacity to strengthen family bonds and how its absence can shape a life just as deeply.

How the body processes alcohol and why that can make you feel so bad is explained by Andrew Scholey, Professor of Human Psychopharmacology at Northumbria University in the UK and member of the Alcohol Hangover Research Group.

Marisa Moll, a registered nutritionist from Paraguay, shares her recommendations on what to consume before you drink alcohol to try to reduce the risk of a hangover.
