BBC Radio 4

Sliced Bread is the series that investigates the latest ad-hyped products and trending fads promising to make us healthier, happier and greener. Are they really 'the best thing since sliced bread'? Science presenter Greg Foot finds out.

Greg speaks to experts on a bunk-busting mission to test the latest consumer trends chosen by listeners. Do they live up to the hype? Or are they just marketing BS?

Greg chats to the experts, dives into the data, performs tests and crunches the numbers before putting his findings back to the listener so they can decide if it's worth spending their hard earned money on.

For this brand new series of Sliced Bread, episodes will be released weekly on Thursdays wherever you get your podcasts. But if you're in the UK, you can listen to the latest episode on BBC Sounds first, a week earlier than anywhere else. 

If you have a suggestion for a product to investigate, you can email the team on sliced.bread@bbc.co.uk or send a WhatsApp voice note via the number 07543 306807.

Sliced Bread is produced by BBC Audio North for BBC Radio 4 and BBC Sounds.

Sliced Bread

Can wonder products halt hair loss and grow back luscious locks?

We're back with a new series of Sliced Bread and a fresh batch of investigations into your suggested wonder products. First up this time are lotions and pills that promise to stop hair loss - and even grow it back. For this episode Greg is joined at our Salford studios by two listeners, Ian and Kimberley. 

Ian got in touch about two products he's seen - Minoxidil and Finasteride - which he hopes can help with male pattern baldness. And listener Kimberley is keen to know whether there's anything she can do about hair loss which is caused by menopause. To get the answers Greg speaks to one of the most cited researchers in the hair loss world - Ralf Paus - as they deep-dive into the studies to separate the science fact from the marketing claims. 

As ever this series it's YOUR suggestions that are the start of all our investigations. 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

The Sliced Bread Christmas List

Can you insulate your home for less than £100?

With winter setting in listener Robin got in touch with Sliced Bread to find out if there's a way he can insulate his very old, very cold Victorian house on a budget. He's seen plastic films that go over the windows and silver foil-type backings that go behind the radiators. Do any of them work to keep the cold out and more of that precious heat in? And what about other solutions like thick curtains or blinds - can they be effective?

Greg is joined in the studio by listener Robin and expert David Farmer from the Energy House in Salford - a bespoke replica terraced house built in a warehouse which can recreate a range of weather conditions, from snowstorms to balmy summer days! 

And as always, all of 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 voice note to our WhatsApp number, 07543 306807.
