Sliced Bread – Details, episodes & analysis

Do more expensive dishwasher tablets clean better? And how do eco versions stack up?

We are back with a new series of Sliced Bread and even more investigations into your suggested wonder products! We'll also be hitting a significant milestone during this batch of programmes so look out for more on that.

First up - dishwasher tablets. Listener Deborah got in touch after hearing our deep-dive into dishwashers themselves and had some burning questions about the tablets we put in them. Do more expensive ones give you a better clean? Do they protect glasses better? And what about the eco brands that promise to be kinder to the environment?

Listener Graham sent a voicenote asking whether buying an 'all-in-one' tablet is better than using separate components, either for cleaning or the environment.

Greg's joined by Deborah and a panel of experts in our studio at Media City in Salford to run all these questions through the wash.

All our investigations start with YOUR suggestions. If you've seen an ad, trend or wonder product promising to make you happier, healthier or greener, email us at sliced.bread@bbc.co.uk OR send a voicenote to our WhatsApp number 07543 306807.

Could fridges make way for kitchen cabinets that don't just keep food fresh but actually grow it?

Dough is a new series from BBC Radio 4 which looks at the business behind profitable, everyday products, assessing where the smart money is going now and what that could mean for all of us in the years ahead.

In this episode, the entrepreneur Sam White speaks with experts from the world of refrigeration including:

Federica Torelli – Head of Product Management with Smeg which makes fridge freezers.

Emir Lasic - Principal Analyst with the industry analysts, Omdia.

Jason Hirst - CEO and founder of EvoGro which makes plant growing cabinets.

Also joining them is the technology expert and applied futurist, Tom Cheesewright, who offers his insight and predictions on what might be coming beyond the current production pipeline.

Together, they explore fridge freezer trends and inventions chatting about their own choices for game changing, and pointless, innovations.

We hear how energy efficiency labels are not always as accurate as you might think and assess the chances of indoor incubators providing a new home for vegetables and leafy greens away from the fridge.

Produced by Viant Siddique & Jon Douglas. Dough is a BBC Audio North production for BBC Radio 4 and BBC Sounds.

Sliced Bread returns for a new batch of investigations in August when Greg Foot will investigate more of the latest so-called wonder products to find out whether they really are the best thing since sliced bread.

In the meantime, Dough is available in the Sliced Bread feed on BBC Sounds

This episode has been edited since broadcast. Twelve year old Bradley got in touch with Sliced Bread after trying out his mum Jennifer’s acupressure mat. Jennifer says she swears by it, it relaxes her, and she even falls asleep on it! But after testing it out himself, he was less than convinced.

He asked us to find out what these mats are meant to do, whether they work or if they’re a placebo effect, and whether paying more for one could mean better results? Joining Greg in the studio to discuss them, is Clinical Acupuncturist Phil Trubshaw from the Manchester Movement Unit based at Manchester Metropolitan University, as well as the Director of Research at the Northern College of Acupuncture, Dr. Karen Charlesworth.

One of your most requested ‘wonder-products’ so far. Heat pumps are promising to not only make our houses greener but to also cut our energy bills. But will they? The Government says every home could have one and have reintroduced grants to help buy them. However Nick wants to know if an air source heat pump would be suitable for the 1930s house he’s about to move into with his family. Given the higher cost of the unit and the extra insulation he needs, will he actually be better off with a new combi boiler instead? Greg speaks to experts, does a survey on his own home and gets Nick answers so he can decide if a heat pump, for him, would be the best thing since sliced bread. Do you have a suggestion of a ‘wonder-product’ making a bold claim that Greg can investigate next?

For many beef connoisseurs, a wagyu steak is the tenderest meat money can buy. They say it literally melts in the mouth. But Pete wants to know, if a Wagyu steak can set you back £100, how can supermarkets sell Wagyu burgers for around £3.50 a pair? How much of what makes wagyu beef so prized trickles down into a burger?

Greg speaks to meat scientist, Martin Anderson, visits a Wagyu farm in Yorkshire, and sets up a blind taste test. All to find out if Wagyu burgers are the best thing between sliced bread.

“Make better. Buy better. Wear it longer.” Lots of fashion brands are including claims like this in their adverts and one item of clothing that’s really getting the stamp of supposed “sustainability” is jeans.

Maddie has asked Greg to look into what “sustainability” actually means when it comes to denim. Is it a term that marks genuine eco-impact, or is it more marketing BS? And, as adverts claim, do “sustainable” jeans last longer?

Greg speaks to an organisation that rates clothing brands’ sustainability credentials and visits Manchester Metropolitan University to hear the results of their ‘rub test’. Do you have a suggestion of a ‘wonder-product’ making a bold claim that Greg can investigate next?

Electric Vehicles: Should you switch? In the first of this new series Greg runs Julian’s suggested wonder-product through the evidence mill and asks whether electric vehicles (EVs) really are the best thing since sliced bread? Julian has heard that switching his old petrol-guzzling banger for a shiny new EV will make him greener? But will it? Electric cars are said to be ‘cleaner’ and ‘cheaper’ to run, but with a higher purchase price than their petrol equivalent - and a greater environmental footprint of manufacture - how many miles would Julian need to drive before his fuel savings off-set these initial costs - both financially and environmentally? Greg tests one of the most popular cars in the UK and hears from experts including Mike Berners-Lee & Vicky Parrot to conclude whether electric vehicles are worth the hype, and your money. And he wants YOUR suggestions for what to investigate next!

Whether it’s cutting out the background chatter to hear the radio, or drowning out the snoring coming from the room next door, the promise of noise cancelling headphones is enticing. But do they live up to the marketing hype?

Are they The Best Thing Since Sliced Bread, or BS?

Greg Foot is joined by BBC 6 Music DJ & Host Mary Anne Hobbs, who lends her professional ear to a pair of noise cancelling headphones. While acoustic engineer Professor Trevor Cox unpicks the science fact from the science fiction.

Teeth whitening toothpastes, strips and gizmos are more popular than ever. But what is the evidence that any of them actually work? And what about the HiSmile Teeth Whitening Kit that's been doing the rounds on social media?

Are these products The Best Thing Since Sliced Bread or marketing BS?

Greg Foot talks to fashion commentator and broadcaster, Grace Woodward about her experience with these products while Professor Martin Ashley, Consultant in Restorative Dentistry at the University Dental Hospital of Manchester, is on hand to separate the science fact from the science fiction.

We all know that sunscreen helps to protect our skin from the sun’s burning rays, but are you sure you’re using the right one? Do you struggle to untangle the UVAs from the UVBs, and the SPFs from the star-ratings?

Greg Foot talks to Antonia Mariconda, beauty writer and founder of the Safety in Beauty Campaign, who knows just how baffled consumers are.

On hand to decode the sunscreen labelling is Dermatologist, Dr Andrew Birnie, from East Kent Hospital University NHS Foundation Trust. Common claims, such as ‘waterproof’ and ‘reef safe’ are also put through the evidence mill.
