Sliced Bread - Series 16: Kitchen Sponges, Cloths and Brushes Jul 23, 2026

Show notes

Which is the most hygienic for cleaning your kitchen?

Most of us will be familiar with the cheap packs of coloured kitchen sponges with the abrasive tops, used for washing dishes and wiping surfaces. But could they be harbouring a host of bacterial baddies?

Listener Caroline wants to know as she uses them regularly and even goes as far as running them through the washing machine to keep them cleaner for longer! Does that really work? And are there concerns about these sponges releasing microplastics? Would alternatives like cloths or brushes be a better option?

To answer all of these questions, presenter Greg Foot is joined by Markus Egert, Professor of Microbiology and Hygiene at Furtwangen University in southwest Germany and one of the authors of a major study into the hygiene of sponges; and Vilde Snekkevik, research scientist at the Norwegian Institute for Water Research in Oslo.

Can a test tell you what's living inside your gut - and what to do about it?

That's what listener Pete Mace asked us, kicking off a brand new series of Sliced Bread! He's seen 'gut microbiome tests' advertised by ZOE, Randox Health and others. They promise to tell you about the bacteria - and other bugs - currently making your intestines their home. Many also claim they'll use this information to make personalised diet recommendations, showing you exactly what you should and shouldn't eat to nurture the right bugs and improve your health. Pete wants to know: what can these tests really tell you? And can they really provide a diet tailored precisely to your personal wellbeing? To find out more, presenter Greg Foot is joined by Dr Nick Ilott, Senior Researcher and lead Bioinformatician at the Oxford Centre for Microbiome Studies; and Dr Fred Warren, group leader at the Quadram Institute who researches how gut microbes interact with food.

Toast - Series 7: Orange Jul 02, 2026

Show notes

Orange was once one of the most recognisable brands in Britain — a mobile network with its iconic slogan “The future’s bright, the future’s Orange”, it helped turn mobile phones from elite business tools into everyday essentials.

But while the Orange name still exists globally, its mobile service disappeared from the UK. So what happened?

BBC Business journalist Sean Farrington investigates how Orange took the UK by storm in the 1990s telecoms boom — and why, at home, it ultimately gave way to a new brand: EE.

Joined by resident business expert and entrepreneur Sam White, Sean explores the bold brand thinking that set Orange apart, the rapid growth that made it a takeover target, and the strategic turning points that reshaped the company.

Along the way, they hear from the people who built the brand, including founding marketer Chris Moss, former executives Linda Kennedy and Stuart Jackson, and former EE CEO Olaf Swantee, to understand how Orange captured the public imagination — and why it couldn’t remain a standalone mobile network in the UK.

At the end, Sam draws her own conclusions: as the future stayed bright but less Orange, was the brand overtaken by change — or did it choose to evolve into something new?

Toast - Series 7: Izal Medicated Toilet Paper Jun 25, 2026

Show notes

Izal medicated toilet paper was once a staple of British bathrooms - a curious cultural icon, remembered as much for its distinctive feel as for its antiseptic promise. Produced for decades by the Sheffield‑based company Newton, Chambers & Co., Izal became woven into the fabric of schools, hospitals and public buildings across the UK.

So how did a product that was everywhere for so long, end up disappearing from shelves, surviving only in nostalgia, and uncomfortable memories?

BBC Business journalist Sean Farrington investigates how Izal medicated toilet paper went from national widespread use to historical footnote, joined by resident business expert and entrepreneur Sam White.

To uncover the story, Sean and Sam dig into industrial archives, public‑health records and the memories of those who grew up with the unmistakable crinkle of Izal.

They hear from former Newton Chambers employees, alongside Dr Alice White - Digital Editor at English Heritage and Historian of Psychology and former Jeyes employees, Nicholas Goodwin and Jayne Howe- who followed the Izal brand closely after it changed hands in the 1980s.

At the end, Sam must draw her own conclusions about the fate of Izal medicated toilet paper - from changing hygiene standards to the rise of softer, more luxurious competitors - and decide whether its decline was inevitable or simply a failure to adapt?

-Chris and Rebecca Pond whose father, Eddie Pond, was Paperchase's co-founder -Timothy Melgund - who ran Paperchase under different ownership for over 20 years and led two management buyouts. -Liz Faulkner - from Jelly Armchair, a company that designs greeting cards and supplied Paperchase.

Toast - Series 7: EasyCinema Jun 11, 2026

Show notes

The EasyJet founder, Sir Stelios Haji-Iannou, tried to shake up the cinema industry by introducing low-cost movie theatres.

Tickets were priced as low as 20p for customers who booked in advance.

So, why didn't EasyCinema take off?

Toast - Series 7: Wilko Jun 04, 2026

Show notes

Wilkinson - or Wilko as it became known - was a privately-owned family business that had been successful for decades, offering low-priced household products from its chain of high street stores.

So why did it falter during a cost-of-living crisis when people were looking for value?

The BBC Business journalist, Sean Farrington, investigates how its stores ended up toast, in the company of resident business expert and entrepreneur, Sam White.

To help explain what happened, Sean and Sam delve into the parliamentary archives and hear from expert guests including Gordon Brown who was Wilkinson's managing director for 15 years and Patrick O'Brien, Research Director at GlobalData who has followed the fortunes of high street names for over a decade. At the end, Sam has to come up with her own conclusions about the fate of Wilko based on what she has just heard.

Sliced Bread - Series 15: Food Containers May 28, 2026

Show notes

Is it ok to store food in plastic containers?

That's the question put by listener Joe Tattersall in this, the last episode in the current series of 'Sliced Bread'. Joe's noticed scuffs and abrasions on his reusable plastic containers and is concerned about whether that increases the risk of 'chemical leaching' into his food, or ingesting microplastics. He's keen to know if alternatives like glass, silicon, or metal containers could better for our health, as well as for the planet.

And what about putting them in the microwave to heat food, using them to freeze food after batch-cooking, or putting them in the dishwasher to clean?

To find out more, presenter Greg Foot is joined by Dr Stephanie Wright, Senior Lecturer in Environmental Toxicology at Imperial College London; and Jane Muncke, Managing Director and Chief Scientific Officer at the Food Packaging Forum.

We're taking a break to prepare another batch of Sliced Bread but we're as hungry as ever for your suggestions of wonder products to investigate. Please do send your ideas to us either on email to sliced.bread@bbc.co.uk or to our WhatsApp number, 07543 306807.

Show notes

What kind of cat litter is best for cats, owners and the environment?

After we looked at dog poo bags for an episode, it's only right that we answer some questions for the cat lovers, around cat litter.

She wanted to know: what is the most absorbent cat litter that doesn't smell, doesn't cause problems for her floors when kicked out of the litter tray and might be better for the environment?

Greg Foot is joined by veterinary surgeon and author of the book What's My Cat Thinking? Dr. Jo Lewis – as well as engineer and former managing director of pet care company Bob Martin, Savi Madden – to get the inside scoop.
