Pots and Pans

What cookware is best for your kitchen?There are a bewildering array of pots and pans on offer: stainless steel saucepans, cast iron skillets, even 10-in-1 cookware systems that use layers of various materials. But do they deliver on their promises to help you reach culinary bliss? Listener Emily wants to know if the ones she's seen live up to the hype or are just marketing BS. What do all the materials do? What about cleaning them? And just what is the much-vaunted 'hot spot' that lights up at a certain temperature?!There are also lingering concerns about non-stock coatings. Are they safe? And what about the alternatives if you're not sure?Please do keep your suggestions coming of wonder products for me to investigate.

Dog dental chews

Gum disease is extremely common in dogs - with some breeds particularly badly affected. So it's no surprise there are all sorts of products on the market offering to clean your pet's teeth - which might be particularly appealing if you don't fancy grabbing a toothbrush and doing the job yourself. As well as chews of many shapes and sizes, there are additives to water - and even seaweed extract to sprinkle on their food. It's a serious business. We've had loads of emails asking us to look into this one - including from listener Sarah, who wants help on behalf of Heidi, her Miniature Schnauzer. To get them some answers, Greg hears from a pet nutritionist and a vet who's an expert in dental care. Are dog dental chews the best thing since sliced bread?PRESENTER: GREG FOOT PRODUCER: TOM MOSELEY

Face Creams

Are more expensive face creams worth it?I'm back with a new series of Sliced Bread to investigate more of your suggested wonder products and I'm starting with one of the most-requested so far. Do more expensive moisturisers, serums and oils live up to the hype? Can they result in smoother, brighter, firmer, healthier skin or is it all just marketing BS? Listener Aristide wants to know whether one of the most expensive products on the market - 'Creme de la Mer' (£80 for 15ml) - has any more evidence to back it up than the cheap moisturiser he uses from the High Street. And listener Fiona is keen to hear about the effectiveness of retinol, one of the most popular ingredients used in creams and serums today.In this episode I'll get the answers with the help of our expert, consultant dermatologist Dr Emma Wedgeworth.Once again this series I'm looking for more of your suggestions for wonder products to investigate.

Sean is joined by the self-made millionaire and serial entrepreneur, Sam White, to conclude what went wrong. Together they look at why a product or business failed, and what we can learn from their stories today. In this episode, Sean talks about wearable tech and Google Glass. These futuristic looking spectacles, with a heads-up display which showed text messages and street directions and allowed users to record video footage of what was happening around them, were named in Time Magazine as one of the best inventions of 2012. There was plenty of hype. Google even demonstrated them by live-streaming a sky dive using Google Glass.But by 2015, just two years after their release, Google announced that Google Glass Explorer, the consumer version of the glasses, was g

Bedding

Can changing your sheets be good for you - and the environment? We've had loads of requests to look at the best way to make your bed - specifically, how all the different options for sheets and pillowcases compare. Cotton seems to be king when it comes to popularity, but is it justified? Listener Rosemary is a linen fan, but wants to know whether eucalyptus bedding lives up to the hype. How do its eco credentials stack up - and what does it feel like? Speaking of feel - silk pillow cases have a reputation for luxury, but listener Cathy wants to know whether sleeping on one will - as the marketing promises - also help your skin and your hair. Could it really help with acne? We'll hear from a dermatologist and a fabrics expert - and there are some surprising answers to this one!If you've seen a claim you'd like investigating, you can email the team on [email protected] or send us a WhatsApp voice note on 07543 306807.PRESENTER: GREG FOOT PRODUCER: TOM MOSELEY

Christmas Trees

Which Christmas tree is better for the environment - real or fake?Everyone loves the smell of a freshly cut pine or spruce but the vast majority of them go to landfill. So would a plastic tree be better?Listener Eleanor wants to have a more sustainable Christmas and has some great questions. Is there a better way to dispose of your real tree? How about a pot grown tree you could use again the next year? And she's even heard about the possibility of renting a Christmas tree - the same one, year after year! Is that a thing?In this frankly festive episode I attempt to get to the root of the problem (sorry!) by speaking to an ecological expert and a journalist who's attempted to rent the whole of Christmas.Presenter: Greg Foot Producer: Simon Hoban

Sports Bras

Are expensive sports bras worth the money? Buying a sports bra can be a baffling experience, not least because of the marketing terminology which is full of buzz-phrases like 'high intensity support', 'specialist materials' and 'racer backs'. Listener Teresa has seen sports bras ranging in price from just a few pounds to three figures and wants to know if paying more means you get greater support. Greg speaks to Professor Joanna Wakefield-Scurr, 'The Bra Professor', to take a deep dive into the science and find out more. Can one sports bra suit all sports, like running and yoga? Does the support reduce over time? And when should you wash or replace your sports bra?

Ice Baths

Do the claims made about Ice Baths hold water? Social media appears to be filled with countless people sitting blissfully in small inflatable ‘ice baths’. Fans of such ‘cold water therapy’ claim that taking a chilly plunge will boost your energy levels, reduce your stress, help you sleep better, and supercharge your recovery after a workout. Listener Laura wants to know if the science backs that up. In this episode, I dip my toe - and the rest of me - into an ice bath to find out. I'm guided by Professor Mike Tipton at the University of Portsmouth, one of the leading academics in the study of cold water and its effects on the body.

Eco-friendly toilet paper

How green can your loo roll be? Lots of companies have sprung up offering what they say are the most eco-friendly ways to wipe - and there's a lot to think about. Listener Barbara buys recycled toilet paper - and wants to know if she's better off buying one of the bamboo options on the market. Jo already buys bamboo but is curious about the difference packaging and delivery options make. To get them some answers, Greg Foot speaks to Shanta Bhavnani from Ethical Consumer magazine, who carried out its 2023 ethical toilet paper guide, and materials expert Dr Eral Bele of University College London, who's studied the properties of bamboo.

Smart Thermostats

Can Smart Thermostats save you money on energy bills? Temperatures are falling and conversations are already turning to whether or not the heating has been turned on! Although energy prices have come down a little since last year, the withdrawal of universal Government support to alleviate the cost could mean bills stay high for a lot of people. Listener Wendy is already doing a lot to save money (having listened to a previous Sliced Bread episode on Portable Heaters - check it out on BBC Sounds!) but she's keen to know if the addition of a Smart Thermostat might make even more of a difference.

Do the pills, wristbands or breathing techniques which claim to stop you from feeling sick on planes, trains and automobiles actually work?

Weighted Blankets

Do weighted blankets reduce stress and help you sleep better? They’ve gone from a middle-aisle fad to being a regular fixture in supermarkets and online stores. Weighted blankets can cost upto £200 and promise to give you a deeper, more restful sleep. But do they? Listener Theresa wanted to know about the science behind them. What is it about the ‘deep touch’ or ‘deep pressure’ stimulation that the manufacturers claim helps us to sleep? They’re also often marketed as offering help with anxiety and autism. Listener Claire runs a support group for children with autism and is keen to know more, so I speak to the lead scientist of a big study into that. And listener Pauline wonders whether there are any health risks associated with weighted blankets?

Is cooking on an electric induction hob better for the planet? And what about our health?

Vapes

Is vaping harmful to your health and to the environment? I'm back with a new series of Sliced Bread and I'm kicking off with a topic many of you have suggested - vapes. They've become controversial largely because of the rise in single-use, or disposable, vapes. Nearly eight million are sold in the UK each week, a figure that's doubled in the past year. And according to the organisation Material Focus, which campaigns to increase recyling rates, five million of those are thrown away. Listener John has spotted them lying around on the pavement and is worried about their effect on the environment. I'm joined by Scott Butler from Material Focus who takes apart a disposable vape and shows me just what's inside and explains why they're harmful to the planet and what can be done to improve recycling. I'm also investigating the reason vapes were introduced in the first place over a decade ago - as a smoking cessation aid. Listener Sam wants to know if they really do help you stop smoking o

Greg Foot gets up close and personal with a box full of hungry mosquitoes to find out. Is it all about DEET or are there alternatives which are just as effective? What about citronella? And how well do bracelets, patches and candles perform? And if you do get bitten, what is the best treatment for a mosquito bite?

Barefoot Shoes

This is one of your most-requested topics and as a keen runner myself I couldn’t wait to get into it. Barefoot shoes claim to encourage you to run in a more ‘natural’ way, landing on your mid or forefoot rather than on your heel. Some brands say they’ll increase your speed and reduce the likelihood of injury. But will they? Listener Sam runs marathons and wants to know if the science backs up the marketing hype. He also wonders whether the wider toebox in barefoot shoes really does allow for our toes to be separated out in a more natural way. It’s not just runners who got in touch either; Jon is a dog walker and is interested in wearing barefoot shoes on a more casual basis. Is there any benefit to that? And what about children? Listener Zoe already wears barefoot shoes herself but wants to know if they might be good for her son, too. In this episode I speak to experts to weigh up the evidence.

Cycle Helmets

Which cycle helmets give you the best protection? I’m a big fan of cycling and so when listener Migue got in touch wanting to know what cycle helmet he should buy next, I was really keen to investigate. Migue wanted to know what factors make a cycle helmet the most effective when it comes to protecting your head: the shape, the material, the fit? He’s seen all sorts of neat tech, including collapsible helmets and ones that fit around your neck and act like airbags! To find out more I speak to an expert at one of the world’s leading helmet testing labs in Virginia, USA. And in researching this episode I also discovered there is a hotly-contested debate about whether cycle helmets should be the focus at all when it comes to safety. Some - including the organisation Cycling UK and the charity Sustrans - argue that introducing tougher rules around helmets would mean far more lives lost through physical inactivity than would be saved in protecting from collisions, which are rare.

UV Sterilisers

During the pandemic, as people sought to protect themselves from Corona Virus, more and more products entered the market claiming to use Ultra Violet light to clean your belongings. These vary from UV wands and lamps, to phone boxes and UV baby bottle sterilisers. You may have seen them advertised online, claiming to kill 99% of viruses and bacteria. But do they deliver, and are they worth it, compared to more traditional methods of cleaning like alcohol wipes, or soap and water... That's what listeners Chris and Ben wanted to know.

Outdoor Clothing

If you’ve ever made the mistake of going for a hike wearing just jeans and a t-shirt you’ll know it can be a pretty sweaty, uncomfortable experience. But it doesn’t have to be that way! There are myriad products promising to keep you dry, warm and protected from whatever the weather can throw at you. Listener Julie is keen to know more about that after she went on an adventure holiday without the right kit, leaving her cold and miserable. She’s heard about fabrics that promise to ‘wick away’ the sweat and others that keep you warm in cold weather and cool when it’s hot. And what about the jackets that claim to stop rain getting in yet still be breathable enough to let vapour and sweat out. How does that work?! I’ll be finding out by speaking to an expert in textile technology and the Gear Editor from the UK’s best-selling walking magazine.

Reusable Nappies

According to recycling charity Wrap, an estimated three billion nappies are thrown away every year in the UK. Concerns over plastic waste and a want to save money have been driving a rise in the popularity of reusable nappies but, as listener Amy asks, are they really better for the planet, and your pocket? Me and the team speak to Wendy Richards, also known as The Nappy Lady. She runs one of the biggest nappy advice and sales websites specialising in reusables. Crunching the numbers with her we look at the complete financial costs of both reusable and disposable nappies, even taking into consideration the extra washing costs needed to clean reusables. But what about the environmental impacts of reusable nappies. Are they really better than disposables when you factor in the energy and water used to clean them? That's what we ask Professor Rob Holdway from Brunel University and Giraffe Innovation. Giraffe Innovation recently completed a thorough study - commissioned by DEFRA, the g

Hay fever treatments

What works to help with the symptoms of hay fever? The better weather’s here but for the millions who have hay fever that just means a runny nose and itchy, streaming eyes. And for some people it’s seriously debilitating – listener Richard got in touch because his wife can’t go out and play with the kids in the spring and summer months. In this episode I’m investigating the treatments that claim to help.

Sales of alcohol-free beer in the UK have more than tripled in the past five years, and you'll find more types of no and low-alcohol beer on sale in your local supermarket.

Snoring Products

Research suggests four in 10 of us do it and it can even get so bad it’s been blamed for the breakdown of relationships. Snoring can be a living nightmare for you and your partner. But what if there was something that works to give you – and the people around you – a more peaceful night’s sleep? Listener Neville got in touch with a recording taken by his wife of him snoring – and it’s pretty loud! He’s seen various solutions from throat sprays to nasal strips and even a chinstrap which literally keeps your mouth shut while you sleep. But do any of them actually work?

Sliced Bread - Sourdough

Is sourdough the best thing since Sliced Bread? It’s the last episode in the current series so I thought it was about time I investigated this! Listener Janet got in touch wanting to know whether sourdough really does live up to the hype. Is it better for our digestive health than other breads? Is it made with fewer additives? And do the cheaper sourdough loaves we can buy in the supermarket really cut it - or are they just ‘sourfaux’? To find out, I went to a baking school to make a sourdough loaf from scratch, learning about the process and ingredients that go to make the sort of sourdough you’d find at an artisan or traditional bakers - and might cost over five pounds. And I speak to one of the world’s leading nutritional experts on bread to find out which types we should eat for our health.

After the Sliced Bread episode on shampoo, a number of listeners got in touch to request a follow-up episode on conditioners. So of course, we obliged. Listener Katie wanted to know what they actually do to our hair, if they can deliver on promises for shinier, smoother, or stronger locks – and whether leave-in treatments could be more effective than conditioners you wash off in the shower? Listener Franziska also got in touch, as she wondered if we could also have a look at heat protection products. She wanted to know what’s in them, can they offer our hair any protection while styling, and is there a difference between the effectiveness of sprays or creams?

Listener Isla, 11, wants to know if bottled water from the UK's biggest selling brands such as Evian and Buxton is cleaner, healthier, cheaper and greener than the stuff that comes from the tap. Greg Foot drills down into the subject, investigating the claims made by manufacturers of bottled water. Does it make any difference if water has spent years underground being "filtered by rocks" before being bottled? Are there more minerals in bottled water than in tap? And even though companies are making more of their bottles from recycled plastic, what’s the environmental impact?

Another listener, Jane, got in touch about laundry sheets – strips of concentrated detergent that go inside the washing machine’s drum. Is the slightly higher cost worth it to cut down on waste?

Sliced Bread - Carbon Negative and Carbon Offsetting

Brands are promising to plant a tree for each can of beer, tshirt, or pair of trainers you buy, offsetting their carbon emissions so they can put an attractive ‘carbon negative’ sticker on a product to show green they - and you - truly are. But how effective is a new forest at offsetting a company’s emissions, what does ‘carbon negative’ really mean, and how do they go about proving they’ve achieved it? Trees are just one type of carbon offset. Another, albeit promising but expensive, option is Direct Air Capture. Could that be the future of long term carbon offsetting? Greg Foot finds out.

Sliced Bread - Meal Replacement Drinks

Huel and Soylent are two of the best known names in ‘complete nutrition’ drinks. More of us are trying them and you can now get pre-made bottles of these concoctions in the food aisle in supermarkets. Firms sell them as an instant alternative to breakfast, lunch and dinner too. But how ‘nutritionally complete’ are these liquid lunches? Listener Tom admits snacking on one in the middle of the afternoon but has questions. Does the fact they start as an ultra processed powder affect how healthy they are? Is it possible to live on them and nothing else? Greg Foot investigates. He talks to a registered dietician, a researcher on a new trial into these products, and Huel's co-founder and Head of Sustainable Nutrition, James Collier.

Sliced Bread - Electric Toothbrushes (& Water Flossers)

Take a look down the aisle of any high street chemist and the array of electric toothbrushes on offer is as dazzling as the teeth they promise to give you. You can pay upto £500 for the latest versions whiose myriad features include interactive apps that give you feedback on your brushing technique. The market is dominated by two big brands, both promising a ‘professional’ clean: Oral B, whose iO brush has an oscillating action and Philips’ Sonicare, which uses tens of thousands of vibrations every minute to clean your teeth. After having to pay a lot more for private treatment because she couldn’t find an NHS dentist in her area, listener Holly got in touch to ask whether getting an electric brush might save her trips to the dentist in future. And wouldcould a more expensive brush really clean her teeth better than a cheaper electric one? Or even the trusty traditional (and far cheaper) manual one she currently uses?!

Sliced Bread - Blue Light Filtering Glasses

According to some businesses, the laptop, phone and TV screens we use every day are causing us big problems. They claim these devices emit concentrations of "harmful blue light" which leaves us with tired eyes and poor sleep. One firm goes even further by suggesting this may contribute to a worrying long term condition, macular degeneration which leaves you with a permanent black hole in the centre of your vision. Their solution? A pair of trendy looking spectacles which claim to filter out this blue light. Listener, Sophie spends roughly 12 hours a day at a screen of some sort. She bought a pair but isn't sure if they work. So she's asked Greg to look into them and find out. We get answers from two leading lights in the science of our eyes. Professor John O'Hagan has been a public health scientist for 46 years and is Visiting Professor in Laser and Optical Radiation Safety at Loughborough University.

Sliced Bread - Air Source Heat Pumps

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?

Sliced Bread - Sustainable Jeans

“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?

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 you

Sliced Bread - CBD Products (Cannabidiol)

CBD, short for cannabidiol, is one of the big buzzwords in health and well being products. A naturally occurring molecule of the cannabis plant, it’s popping up in everything - aside from the CBD oil tinctures, you can now eat it, down it in drinks, vape it, lather it on your skin and soak in it. You can even buy sports leggings infused with it. Consumer interest in CBD-based products shows no sign of abating, with enthusiasts claiming a whole host of benefits from relieving anxiety, to easing pain and helping us sleep. The theory behind how CBD might work seems promising - CBD shares similarities with endocannabinoids, produced naturally in the body, which help to regulate stress, sleep, metabolism, memory, inflammation, and immunity. Given the deluge of different CBD-based products, should we really believe the hype?
