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.

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?

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 [email protected] OR send a voicenote to our WhatsApp number 07543 306807.

Listener Chris from Suffolk recently took a DNA ancestry test, and after getting some interesting results back, he wondered how accurate they really were?
Greg Foot finds out by taking two tests himself – and has the results and his family tree revealed to him by DNA Genealogist from Finding Families, Louise Baldock.
He also speaks to Professor of Genetics at Leicester University Mark Jobling to find out what these companies are looking for, what they can or can’t determine from our DNA in terms of where we came from, and asks the question – is sharing our DNA with these companies safe?
All of the ideas for our investigations come from you, our listeners, and we’re always on the lookout for more.

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.

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?

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).

Listener Jennifer is considering switching contact lenses, if there's an alternative that's more eco friendly. She's not alone - we've had lots of questions about eyecare options, and whether the fancy features some lenses offer are worth the extra cash. Joining Greg and Jennifer in the studio to talk all things contact lens are Daniel Hardiman-McCartney, a clinical adviser to the College of Optometrists, and Sarah Smith - a research optometrist who's studied the environmental impact of these tiny pieces of plastic.

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. So do you really need to pay more to get a good tyre?
Listener Ian runs a car maintenance business and wants to know if the budget tyres he's been fitting are the right choice. Will they last as long and be just as safe? What do the different ratings on the labels you can see online mean? And as he moves towards electric cars he's also keen to know whether they need a special sort of tyre.
With the help of two experts in the field, Greg Foot 'treads' through the studies and the science to find out more. It's how he rolls (we'll stop now).

Lots of different types of period products claim to be eco friendly, from menstrual cups to period pants and reusable pads. But how do their environmental credentials stack up? That's what listener Sam wants to know - and she's not the only one asking about not just the impact of these so called sustainable period products on planetary health, but also on women's health too. Joining Sam and Greg for this one are Natalie Fee, founder of the non profit City to Sea, who campaigns for "plastic-free periods", and Dr Nicola Tempest, a senior lecturer in gynaecology at Liverpool University.

The UK market for air care products is expected to grow to £674 million this year - and for this episode, we're investigating just how these products tackle bad smells in our homes. Can air fresheners really "eliminate" stinky odours with science, or do they just smell nicer? And what does using them do for our air quality? That's what listener Conor from Manchester wants to know. He joins Greg in the studio, alongside two experts - Nicola Carslaw, a professor in indoor air chemistry‘ at the University of York, and emeritus professor of chemo-reception at the University of Manchester, Krishna Persaud.
