Is it OK to take experimental peptides like the Wolverine Stack?These are what bodybuilders, longevity gurus, and online influencers are all talking about: experimental peptides. They're chemicals that you can buy online, in packages with names like the Wolverine Stack or the Glow Stack. The websites say "for research purposes only" but talk about their supposed benefits for wound healing and de-aging, and lots of people have been injecting them in a bid to heal faster and look younger.Sliced Bread listener Steve is excited - and has even tried them for himself - but listener Sophie is worried. Both of them are asking whether there's any evidence behind the fantastic claims.To find out the truth, Greg Foot is joined by Dr Andrew Steele, longevity scientist and Director of the Longevity Initiative.All of our episodes start with YOUR suggestions.

What makes the perfect pillow? Nothing saying ‘waking up on the wrong side of the bed' like a crick in your neck. With up to 70% of us experiencing neck pain at some point in our lives, sleeping in a dodgy position can lead to days of discomfort. And pillows might be part of the problem... Listener Angela has a frozen shoulder, and hoped a new pillow might provide a more comfortable night's sleep. But with so many options to chose from, which one should she buy? One advertised for her preferred sleeping position? Soft or firm? And what about material: feathers, foam or fibre? She's asked Sliced Bread to help pick out the facts from the marketing fluff.Physiotherapist Dr Chris McCarthy from Manchester School of Physiotherapy joins presenter Greg Foot to discuss the most important factors in selecting the perfect pillow, personalised to you - plus, how to save your sleep when faced with a floppy hotel pillow...All of our episodes start with YOUR suggestions.

What's the best way to keep your home cool?As heatwave after heatwave pushes temperatures higher across the UK and Europe, air conditioning has become a serious topic. Listener Rachel is one of many people who have turned to a portable air conditioner for relief. About the size of a dehumidifier, these units cool a room by drawing in warm air, chilling it, and venting the excess heat outside through a hose, usually attached to a window.But with hotter summers forecast, Rachel is wondering whether it's worth investing in a fixed, or "split", air conditioning system instead. These systems use an indoor unit paired with an outdoor condenser and are increasingly common in homes across Europe. She wants to know: how much do they cost to buy and run? Are they difficult to install? And how noisy are they in everyday use?Then there are the cheaper "air coolers" that claim to lower temperatures by blowing air over cold water or ice. Do they genuinely cool a room, or are they simply fans with clever marketing?To find out, presenter Greg Foot is joined by Rachel and Professor Richard Fitton, Technical Director of the Energy House 2.0 test facility at the University of Salford.All of our episodes start with your suggestions.

Which is the most hygienic for cleaning your kitchen?Most of us will be familiar with the cheap packs of coloured kitchen sponges with the abrasive tops, used for washing dishes and wiping surfaces. But could they be harbouring a host of bacterial baddies?Listener Caroline wants to know as she uses them regularly and even goes as far as running them through the washing machine to keep them cleaner for longer! Does that really work? And are there concerns about these sponges releasing microplastics? Would alternatives like cloths or brushes be a better option?To answer all of these questions, presenter Greg Foot is joined by Markus Egert, Professor of Microbiology and Hygiene at Furtwangen University in southwest Germany and one of the authors of a major study into the hygiene of sponges; and Vilde Snekkevik, research scientist at the Norwegian Institute for Water Research in Oslo.All of our episodes start with YOUR suggestions.

Can a test tell you what's living inside your gut - and what to do about it?That's what listener Pete Mace asked us, kicking off a brand new series of Sliced Bread! He's seen 'gut microbiome tests' advertised by ZOE, Randox Health and others. They promise to tell you about the bacteria - and other bugs - currently making your intestines their home. Many also claim they'll use this information to make personalised diet recommendations, showing you exactly what you should and shouldn't eat to nurture the right bugs and improve your health. Pete wants to know: what can these tests really tell you? And can they really provide a diet tailored precisely to your personal wellbeing? To find out more, presenter Greg Foot is joined by Dr Nick Ilott, Senior Researcher and lead Bioinformatician at the Oxford Centre for Microbiome Studies; and Dr Fred Warren, group leader at the Quadram Institute who researches how gut microbes interact with food.

Is it ok to store food in plastic containers?That's the question put by listener Joe Tattersall in this, the last episode in the current series of 'Sliced Bread'. Joe's noticed scuffs and abrasions on his reusable plastic containers and is concerned about whether that increases the risk of 'chemical leaching' into his food, or ingesting microplastics. He's keen to know if alternatives like glass, silicon, or metal containers could better for our health, as well as for the planet.And what about putting them in the microwave to heat food, using them to freeze food after batch-cooking, or putting them in the dishwasher to clean? To find out more, presenter Greg Foot is joined by Dr Stephanie Wright, Senior Lecturer in Environmental Toxicology at Imperial College London; and Jane Muncke, Managing Director and Chief Scientific Officer at the Food Packaging Forum.We're taking a break to prepare another batch of Sliced Bread but we're as hungry as ever for your suggestions of wonder products to investigate.

Are infrared saunas as effective as traditional ones?If you've ever sat sweating on a wooden bench in a traditional ('Finnish') sauna wondering if there was an easier way, could infrared be the answer? Infrared saunas work at lower temperatures, ostensibly making it easier to stay in there for longer. Listener Paul got in touch after trying one and wants to know if infrared saunas give you the same purported benefits as traditional ones.
