Sliced Bread Podcast
Greg Foot investigates the so-called wonder products making bold claims. Are they the best thing since sliced bread, or marketing BS?
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.
New episodes of Sliced Bread are released weekly on Thursdays wherever you get your podcasts. But 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.
