Can fortified drinks and spreads really reduce cholesterol?Almost half of UK adults have raised cholesterol, according to the charity Heart UK - and Sliced Bread listener Cathy is one of them. She found out after taking a test at her GP and wants to do something about it. Her first plan of action is to make changes to her lifestyle, such as diet and exercise. As part of that, Cathy wants to know if the spreads and drinks that claim to lower cholesterol really do work. Greg Foot is joined by Cathy and a panel of experts at our studios in Salford to investigate. What are the ingredients that are proven to lower cholesterol? How effective are they compared to widely-prescribed statins - and are the supermarket own brand versions of these drinks and spreads just as good as branded ones?All of the ideas for our investigations come from you, our listeners, and we're always on the lookout for more.

This episode has been edited since broadcast. Twelve year old Bradley got in touch with Sliced Bread after trying out his mum Jennifer’s acupressure mat. Jennifer says she swears by it, it relaxes her, and she even falls asleep on it! But after testing it out himself, he was less than convinced. He asked us to find out what these mats are meant to do, whether they work or if they’re a placebo effect, and whether paying more for one could mean better results? Joining Greg in the studio to discuss them, is Clinical Acupuncturist Phil Trubshaw from the Manchester Movement Unit based at Manchester Metropolitan University, as well as the Director of Research at the Northern College of Acupuncture, Dr. Karen Charlesworth.

What's the best - and most humane - way to get rid of pests?For some of us Tom and Jerry might be the sum total of our knowledge of the struggle between domestic life and unwanted rodents. But for listeners Colin and Mary, things are getting much more real! Colin wants to know if the plug-in devices he's seen that promise to deter rats and mice using ultrasonic actually work. Mary has caught mice and then released them back into the wild in nearby woodland, believing it's the more humane way to deal with the problem. But is it?With the help of Natalie Bungay from the British Pest Control Association and Rob Young, Professor of Wildlife Conservation at the University of Salford, Greg Foot sets out to find the answers, hoping to nibble at the metaphorical cheese without getting caught in the figurative trap (or something).All of the ideas for our investigations come from you, our listeners, and we're always on the lookout for more.

Is it worth paying more for premium car tyres?There's a huge range of car tyres to choose from and the price differences between them can be significant.

This one's all about mushrooms - not so much your chestnut, button or portobellos from the supermarket, but more the likes of lion's mane, reishi and chaga. These much-feted fungi are claimed to offer all sorts of benefits, from relaxation to disease-fighting properties. We've had loads of questions about products containing them, particularly around mushroom coffee. Is there any evidence that it's better for you than your regular brew? Listener Leon is fond of it - and wants to know if there's any science to back up his inclination. To get him some answers, we hear from a registered nutritionist and a mycologist (fungi expert) who's just written a book all about medicinal mushrooms.

To find out, we speak to a man who's spent decades studying the differences - Professor Rainer Stamminger from the University of Bonn in Germany.Eve also wants to know about the eco settings on dishwashers: how can they save money if they take so much longer? And should you pre-rinse before putting things in?! In short, does the evidence around dishwashers stack up (sorry!) Greg will be finding out.PRESENTER: Greg Foot PRODUCER: Simon Hoban

Greg's getting electric for this one, as he tries out a tens machine. Tens (transcutaneous electrical nerve stimulation) is a type of pain relief which uses a mild electrical current. They're marketed at all types of pain - but do they work? The NHS isn't convinced yet. Listener Patrick is one of many who have asked about these devices, so we got in touch with a a professor who's studied them for 40 years. Also - another type of electrotherapy is a circulation booster. These circular devices claim to be able to help sore legs by activating the muscles. On behalf of listener Rick, Greg finds out what the evidence is for their effectiveness.PRODUCER: TOM MOSELEY PRESENTER: GREG FOOT

Which is the cream of the crop for your health and the planet?The supermarket shelves are fairly bulging with plant-based options for people who either prefer not to drink cow's milk or can't for health reasons like an allergy. Some have been around for a while - like soy, almond and the current best-seller in the UK, oat - but there are newer additions to consider like hazelnut, hemp and a drink made from dried peas.Listener Sian wants to know if these milk alternatives are better for her health and the environment than cow's milk. Do they give you the same nutritional benefits? And what's the carbon footprint of each, and how do they compare to the production of cow's milk?

Greg Foot gets queasy in the name of science as he investigates the range of products promising to help with motion sickness.Do the pills, wristbands or breathing techniques which claim to stop you from feeling sick on planes, trains and automobiles actually work?To find out, Greg heads to Professor John Golding's laboratory at the University of Westminster where a spinning chair is used to induce symptoms of motion sickness. Why don't scientifically-proven treatments always work for everyone?

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?Once again this series we’re testing and investigating your suggested wonder-products, so if you’ve seen an ad, trend or fad, and wonder if there’s any evidence to back up a claim, drop us an email to [email protected] or you can send us a voice note to our WhatsApp number: 07543 306807.Presenter: Greg Foot Producer: Simon Hoban

Induction hobs are not just a fashionable addition to a new kitchen, but are also sold as a more efficient choice than a gas hob. How do they compare? Is cooking on an electric induction hob better for the planet? And what about our health? Listener Roisin wants to know if they are an economical choice but worries they might affect her mum's pacemaker, while listener Anna is concerned about indoor air pollution from gas cookers and wonders if induction hobs are a safer bet. Greg Foot gets them some answers with expert help from Emily Seymour, the Energy Editor at Which? and Jonathan Grigg, Professor of Paediatric Respiratory and Environmental Medicine at Queen Mary University of London.

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 or whether the convenience of disposable vapes means they just prolong or even worsen the addiction? I speak to Professor Anne McNeill, co-author of a landmark review into the health impact of vapes and their effectiveness when it comes to helping people stop smoking compared to previous treatments like nicotine patches or gum.

If you are heading somewhere tropical this summer, or just want to protect yourself from bites in your own back garden, then which mosquito repellents can you trust?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?Greg assesses the scientific evidence with Professor James Logan from the London School of Hygiene and Tropical Medicine and Dr Jane Wilcock, an indepedent researcher and GP.

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. Are barefoot shoes the best thing since sliced bread? Or just marketing BS?PRESENTER: Greg Foot PRODUCER: Simon Hoban

Owners clearing up after the UK's 11 million estimated pet dogs have a bewildering array of bags from which to choose. Some are labelled 'degradable', others are called 'biodegradable', 'compostable and biodegradable' or 'recycled.' So which ones are best for the environment? And what is the most environmentally friendly way of disposing of our dogs' doo?Greg Foot is on the case on behalf of listeners including Nicola Jones and Craig Hart who are perplexed by the claims being made on dog poo bags.

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. That’s a view shared by Dr Ian Walker from Swansea University, who also features in this episode.Once again this series we’re testing and investigating your suggested wonder-products, so if you’ve seen an ad, trend or fad, and wonder if there’s any evidence to back up a claim, drop us an email to [email protected] or you can send us a voice note to our WhatsApp number: 07543 306807PRESENTER: Greg FootPRODUCER: Simon Hoban “

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.I'll be finding out by speaking to an expert in radiation safety Professor John O'Hagan at Loughborough University and Matt Knight, Product Testing Expert at the consumer group Which?Once again this series we’re testing and investigating your suggested wonder-products, so if you’ve seen an ad, trend or fad, and wonder if there’s any evidence to back up a claim, drop us an email to [email protected] or you can send us a voice note to our WhatsApp number: 07543 306807PRESENTER: Greg FootPRODUCER: Jay Unger

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.Once again this series we’re testing and investigating your suggested wonder-products, so if you’ve seen an ad, trend or fad, and wonder if there’s any evidence to back up a claim, drop us an email to [email protected] or you can send us a voice note to our WhatsApp number: 07543 306807PRESENTER: Greg Foot PRODUCER: Simon Hoban

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 government’s Department for Environment, Food and Rural Affairs - looking at exactly this.Once again this series we’re testing and investigating your suggested wonder-products, so if you’ve seen an ad, trend or fad, and wonder if there’s any evidence to back up a claim, drop us an email to [email protected] or you can send us a voice note to our WhatsApp number: 07543 306807.

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. I speak to an expert from Allergy UK to find out what works and whether - as listener Lisa wonders - the generic or own-brand versions work as well as the more expensive branded ones. And could a hay fever injection be the one-shot solution Richard’s wife is looking for?Also, you might have heard about the gut microbiome…but did you know there’s a nasal microbiome too?! I’m finding out about some new research which shows probiotics could play a role in treating hay fever.This series we’re testing and investigating your suggested wonder-products, so if you’ve seen an ad, trend or fad, and wonder if there’s any evidence to back up a claim, drop us an email to [email protected] or you can send us a voice note to our WhatsApp number: 07543 306807.PRESENTER: Greg Foot PRODUCER: Simon Hoban

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. But what does 'alcohol-free' really mean? And are these drinks always better for your health? Various listeners got in touch with us about this one, so we enlisted the help of two experts to answer their questions. Laura Willoughby knows a lot about no/low alcohol beer as co-founder of Club Soda which says it exists "to help people drink more mindfully and live well”. Kerry Torrens is a registered nutritionist who has been working in the food and drink sector for two decades.

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? Are they the best thing since Sliced Bread – or marketing BS?I speak to experts to find out including an Ear, Nose and Throat surgeon and a scientist who’s looked into the extreme end of snoring.
