Sliced Bread - Series 11: Lip Balm May 15, 2025

Show notes

When staring at shelves full of sticks, tubs and tubes all promising us the perfect pout, how do you know which Lip Balms will really help keep chapped lips at bay?

Listener Kiran is a regular lip balm applier - saying she often suffers with dry or cracked lips, and recently splashed out on an expensive lip balm after seeing celebrity endorsed adverts for it online. But she isn’t sure it’s any better than her trusty tub of Vaseline.

To find out, Greg Foot speaks to Consultant Dermatologist and Dermatological Surgeon Dr Emma Craythorne about lips, lip lickers, mouth breathers and the causes of cracking - as well as lecturer in pharmaceutical and medicinal chemistry at the University of Sunderland, Dr Teresa Borrello about what is IN these lip balms to plump, smooth, or repair.

Sliced Bread - Series 11: Sleep Headbands and Sleep Bars May 08, 2025

Show notes

Which products are best for bedtime listening?

According to a YouGov poll nearly half of us listen to music or podcasts to help us get to sleep and there are a range of products designed to do just that.

Listener Nick has seen wearable sleep headbands with speakers woven in to the fabric which he hopes will stop him waking up in the middle of the night with headphones or earbuds digging into his ears.

And listener David says his social media is promoting sleep bars that go under the pillow and claim to transmit sound via bone conduction.

To find out more, Greg is joined by acoustic expert Professor Trevor Cox and Lecturer at the Surrey Sleep Research Centre, Ullrich Bartsch. They discuss the sound quality of these devices and whether it's a good idea to listen to music or podcasts at bedtime at all. Is there any evidence that it results in a good night's sleep?

Sliced Bread - Series 11: Plant-Based Meat Alternatives May 01, 2025

Show notes

You may have heard health warnings around too much red or processed meat, and considered trying a plant based meat alternative as one of your midweek meals instead. But after looking at the ingredients on the packet and spotting salt, additives and flavourings, wondered if they really are the healthier choice?

That’s exactly what listener Graham did, as he hunted for an alternative to his beloved sausage – and found that the plant based versions all seemed to be heavily processed. He's asking, are they really better for us? And are they better for the environment too?

The information and prices in this episode were correct at the time of recording.

Show notes

Are there products that can help you avoid or ease jet lag?

If you've travelled long-haul you'll know the feeling; your body feels completely out of sync with the new time zone, leaving you tired, disorientated and quite possibly a tad irritated!

So is there anything you can do? Listener Moira suffered the effects of jet lag on a recent work trip to India and with another one coming up to the USA, she's keen to know more about the products that claim to help. She's heard about apps that help you align your circadian rhythm with your new time zone, as well as supplements and even a mask that promises to better humidify the air on your flight! But do any of them work?

Sliced Bread - Series 11: Artificial Sweeteners Apr 17, 2025

Show notes

Artificial sweeteners appeal to anyone with a sweet tooth looking to cut down on their sugar intake. They’re not only for use in our cups of tea or coffee, but they’re also in fizzy drinks, low calorie products, sweets and baked goods. But are they really a better alternative?

Greg is joined by a leading scientist from the World Health Organisation, as well as a Professor of Gastroenterology who has researched the impact of sweeteners to “spill the tea” on this topic. Can using them as an alternative help us reduce our blood sugar? Are all kinds of sweetener safe? And what about their effects on us long term?

Show notes

Can home tests tell you if you have an allergy or a food intolerance?

We're back with a new batch of investigations and kicking off this series is one of our most popular requests: home allergy tests. The companies that make them claim they can help you work out if you have an allergy or intolerance to certain foods. The idea is the information can help you decide what to eliminate from your diet. But do they work?

Greg is joined by consultant allergist Professor Adam Fox to do a deep-dive and separate out the science fact from the marketing fiction.
