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?

Edinburgh gardener Alan got in touch with Sliced Bread, to ask if he really needs to be spending money on buying and applying plant food or fish, blood and bone meal to his roses and woody perennials? He was keen to know what is in these commercial plant foods that come as a solid, liquid or granule, how often he is supposed to use them, whether they make as much of a difference as they claim, and if he can save money by making his own “mulch” out of fallen leaves? Greg Foot investigates with the help of Gardener's Question Time's expert and botanist, Pippa Greenwood – as well as Head of Fertilisers from the Agricultural Industries Confederation Jo Gilbertson. They “dig in” to the claims on the packets, and try to determine if pricey plant foods are the best thing since Sliced Bread?We are looking for more of YOUR suggestions of products to investigate.

Do Boiling Water Taps save you money?They're often seen in offices but boiling water taps are increasingly popular for the home kitchen too. They hold hot water at a constant temperature in a tank under your sink and claim to save you money compared to boiling a regular kettle. But does the evidence back up the marketing hype?Listener Jenny got in touch with Sliced Bread because she's upgrading her kitchen and is thinking about investing in a boiling water tap. She's keen to know how the figures for daily use stack up - and if there IS a saving how long it would take before she gets her money back on the original outlay.

Grounding Sheets - do they really work?It's perhaps the most-requested product in Sliced Bread history but is there any real science behind grounding (or 'earthing') sheets? The claims made for them are wide and varied - from reducing inflammation and pain, to helping with sleep. How do they do this? Proponents say grounding sheets connect you to the Earth's own electrical field and dissipate electrical charges in your body, built up though everyday activities like wearing rubber-soled trainers. Prices of grounding sheets vary from £30 to £150.Listener Alison is thinking of buying one and wants to know if it could ease pain and help her sleep better. She joins Greg in the studio along with two experts for a deep-dive into the science to find out whether grounding sheets are the best thing since sliced bread - or marketing BS.We are looking for more of YOUR suggestions of products to investigate.

Listener Helen from Manchester got in touch to ask about Protein Powders, as she considered replenishing her supply that she's been taking after long distance runs. She wanted to know if Whey or Plant-based protein really can help her build and repair muscle, whether there's a set amount she should be having, if one type is better than the other, or if she could just get the protein she needs from her food – and save on buying another bag?Greg Foot brings back Professor of Human Physiology, Sport and Exercise Sciences at Liverpool, John Moores University, Graeme Close to answer Helen's questions, tell us what our body needs and uses protein for, and whether it really can deliver ‘Gainz' (with a Z.)As always, all of our investigations start with YOUR suggestions.

Listener Steve got in touch with us after trying out a set of Smart Scales himself. He wanted to keep an eye on his protein levels – which his scales claimed to do – for health reasons, and because he'd heard that we need more protein as we get older. His scales also promised to show him his body fat, muscle mass, and bone mass via a corresponding app on his phone. However, some of those readings didn't seem quite right – making him question how accurate his scales are, and if they can REALLY tell you so much about yourself? Greg Foot asks two experts - a GP and a professor of applied mathematics – to weigh in on the topic, and find out whether these scales can measure up.

Listener Raffi is tired of his morning coffee going cold by the time he's ready to drink it. There are plenty of products out there promising to do a better job than Raffi's flask, and they come with a range of price tags. But how do they work and what is the ideal drinking temperature? Dr Michael de Podesta, a chartered physicist and measurements expert, has been looking into these very questions. He joins Greg and Raffi in the studio to run through his experiments - and explain how 'double walled technology' works and whether it's the answer to Raffi's prayers. Michael's even been trying out a high tech cup that claims to instantly cool your drink to a perfect drinking temperature - and keep it there for hours. Insulated cups also claim to be leak proof, durable and - in some cases - dishwasher proof. So joining them for this one is Kamisha Darroux, principal scientific adviser for Which? to talk about the tests they do and which other features are worth spending your money on. So are insulated coffee cups the best thing since sliced bread?PRESENTER: GREG FOOT PRODUCER: TOM MOSELEY

Greens powders are made up of dozens of ingredients, which are ground up and added to water. They claim to do all sorts of things for our bodies, like give us extra energy, clearer skin, boost our gut health and reduce bloating. But they're not cheap. So what's in them and do they work? That's what listener Sofie, whose social feeds have been bombarded with adverts for greens powders, wants to know. She's not alone - we've had lots of messages asking us to look into these products. To get some answers, Greg speaks to British Dietetic Association spokeswoman Sian Porter, and food scientist Dr Emily Leeming. The prices of the products were correct at the time of the recording.PRESENTER: GREG FOOT PRODUCER: TOM MOSELEY

Lots of people use a foam roller, either before after exercise. It's not usually a very comfortable experience - as Greg finds out in this episode - but is worth the pain? Can they really increase flexibility before exercise, and ease our muscles afterwards? Is it any better than stretching? As you'd expect, there are plenty of claims around these products, which cost anything from a tenner to more than £100 for a vibrating version. We're going right around the world for this one - listener Brendon joins us all the way from New Zealand, and to get him some answers we've got foam roller expert Dr David Behm dialling in from Canada. National Physiotherapy Lead for Nuffield Health Jodie Breach also joins Greg in the studio. So are foam rollers the best thing since sliced bread?PRESENTER: GREG FOOT PRODUCER: TOM MOSELEY

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.

Are the latest ear plugs better for gigs, focus and sleep?In this special edition of Sliced Bread, recorded at the Hay Festival in South Wales, Greg Foot investigates the newer style of ear plugs. He's joined by listener Marni who's seen adverts for brands like Loop, which promise to protect your hearing at higher volumes while still allowing you to enjoy music at gigs. Other models in their range claim to give you better focus, shutting out extraneous noise but still allowing you to hear conversation. Or, in the case of their 'Quiet' model, sleep better.As ever Greg's joined by two experts to deep-dive into the science and find out if the evidence backs up the marketing claims. And with the help of a special dummy head fitted with microphones, they carry out a series of tests to hear the difference between traditional foam ear plugs and the newer models.
