Sliced Bread

• Plant Food

  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.

• Boiling Water Taps

  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. And then there's maintenance too...Greg is joined in the studio by Jenny and energy expert Mark Thompson to crunch the numbers, along with Debbie Birkbeck from Stopcocks Women Plumbers.

• Grounding Sheets

  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.

• Cooking Oils

  Which cooking oils are best for your health?Listener Sarah got in touch after seeing claims on social media that more expensive oils are better for you than regular vegetable, or rapeseed oil. And listener Kamal sent us a voicenote asking about coconut and avocado oil - both touted as healthier alternatives to other types of oil. Are they worth the extra cost? And what about health concerns if certain oils are overheated? To get the answers Greg is joined by Professor of Population Health and Nutrition at the University of Cambridge, Nita Forouhi. Together they deep-dive into the studies and evidence, finding out what compounds constitute a healthy oil and giving advice on what we should be looking out for on the bottle. All of our investigations start with YOUR suggestions.

• Protein Powder

  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.
