What's the science behind a sweet tooth? James Gallagher explores whether sugar really can be addicted and what happens in our bodies when we want it and when we eat it. 

He's joined by Professor Susanne Dickson, who specialises in the neurobiology of appetite at the University of Gothenburg, and Professor James Brown from the School of Biosciences at Aston University.

With Easter coming up, James meets dental hygienist and researcher Dr Claire McCarthy from King's College London in the BBC loos to get some top tips on keeping our teeth clean and gets a few pointers on where he could do with brushing up on his technique.

Have you ever tried intermittent fasting? As the month of Ramadan comes to an end, many Muslims are concluding several weeks of time-restricted eating. But outside of religion, many of us are now choosing to eat this way for health reasons – even UK PM Rishi Sunak does a weekly fast. Claimed benefits of intermittent fasting range from weight loss to improved immune function to maybe even living longer, but do these stack up? 

James Gallagher gives one of these popular diets a go whilst trying to answer if restricting when we eat our food is good for us. He chats to Colin Selman from the University of Glasgow about the animal studies which inspired these claims, Claudia Langenberg from Queen Mary University on what happens in our bodies when fasting, and Lucy Serpell from UCL on the potential dangers these types of diets can pose. Plus, we visit AFC Wimbledon for an Iftar event to hear if people fasting during Ramadan experience any changes to their health.

Is intermittent fasting good for you?

It has been a cold start to the year and for many that means the heating's on, windows are shut and we're drying clothes inside the house. For many people, mould becomes a major concern in winter and the health problems mould can cause have been under more scrutiny since the death of two-year-old Awaab Ishak who died in 2020 from long-term exposure to mould at his home in Rochdale.

At Imperial College London a study called WellHome is underway to monitor levels of mould and other indoor pollutants in homes across the west of the capital. Presenter James Gallagher meets Mum of four Roxanne who had monitoring equipment installed in her house to collect data that could lead to guidance on housing quality and inform how healthcare professionals look for and treat conditions affected by mould. 

Joining James at Roxanne's is WellHome's Dr Athena Trachalaki, a Respiratory Registrar with Imperial College NHS trust. With her, to go through all the pollutants that pose a risk to our health indoors is WellHome lead and Professor of Community Health and Policy at Imperial College, Frank Kelly. 

Dr Jonathan Grigg, Professor of Paediatric Respiratory and Environmental Medicine at Queen Mary University, London, tells James it could be the end of the line for the gas cooker, and Professor Alastair Lewis who is Professor of Atmospheric Chemistry at the University of York takes a virtual tour of James's home to discuss all the ways James could be cleaning up the air he breathes.

Mould and Indoor Air Pollution: How Concerned Should You Be?

From kombucha to cold water swims, sleep to supplements, so many things are claimed to help enhance your immune system. We investigate the evidence, and ask if it's possible to avoid catching a virus this winter (and still leave the house). 

Plus, James braves 3.9 degree water to see for himself if cold water swimming has any affect on our immune systems.

Raw milk: What are the risks and why are people talking about it?

James Gallagher discusses the risk from H5N1 bird flu in the UK as a poultry worker in the West Midlands is infected and looks to the US where the disease is spreading in cattle. He's joined by virologist Dr Ed Hutchinson from the University of Glasgow to discuss how the virus is evolving, whether we are edging closer to bird flu becoming a pandemic and how it's being handled in the US as President Trump's government takes office.

Also, you've been sending in your questions on embarrassing health problems and lots of you have asked about the problem of leaking urine, known as urinary incontinence. James puts your questions to Dr Vanessa Apea, a consultant physician in Genito-urinary and HIV medicine at Barts Health NHS Trust and an Honorary Senior Lecturer at Queen Mary University of London.

Bird flu update after UK farm worker infected and your questions on urinary problems

You sent in your questions on dementia and now we're tackling them. Professor Tara Spires-Jones, Director of the Centre for Discovery Brain Sciences at the University of Edinburgh, joins James Gallagher to go through the insidehealth@bbc.co.uk mailbag.

James also visits mushroom grower the Bristol Fungarium which has teamed up with the University of the West of England to examine a mushroom called lion's mane.

Lion's mane has a lot of hype about it online as well as a long history in traditional medicine and neuroscientist Dr Tim Craig and his team are taking it into their to lab to investigate whether it might harbour properties that could benefit people with dementia.

Thanks to everyone who sent in questions after listening to our episode 'What next for Alzheimer's treatment' which is available on BBC Sounds: https://www.bbc.co.uk/programmes/m0024ng7

Dementia: Your questions answered and lion's mane mushrooms in the lab

Has James been buying shoes that are bad his feet? He meets podiatrist Dao Tunprasert to find out how healthy his shoes are. Also, returning to our theme of health conditions you find embarrassing, we get the lowdown on genital herpes from Dr Vanessa Apea. She's consultant physician in Genito-urinary and HIV medicine at Barts Health NHS Trust and an Honorary Senior Lecturer at Queen Mary University of London and answers some of your questions.

How shoes affect our bodies and a focus on genital herpes

When we hit our teens it's often a time when everything starts to change. We meet new friends through work or studies, we start going out more at night and we're often in new situations independent from our parents. For people with severe allergies it can be a risky time because they have all this change in their life, on top of what Priya Matharu calls the 'full time job' of managing your condition. Presenter James Gallagher talks to Priya about her experience of having severe allergies from a young age and how she has coped with reactions that mean just touching her face after chopping a carrot has put her in hospital. For Priya, when she reached adolescence and moved out of her family it was a scary time and she had to grow up quickly to take responsibility for her allergies. 

In a recent debate in the House of Lords it was discussed that moving young people out of the paediatric allergy services they have grown up with the support of and into adult services, just as everything else in their life is changing too can be really difficult for patients, and potentially dangerous. 

Dr Claudia Gore from Imperial College Healthcare NHS Trust shared her experience of working in a children's allergy clinic in London for that debate and she joins James along with Dr Paul Turner from Imperial College London to discuss how this transition from children's to adult services could be made safer and smoother for patients.

Also in the programme, James is joined again by Dr Vanessa Apea, Consultant in Genito-Urinary and HIV medicine at Barts Health NHS Trust to answer more of your questions on genital herpes, UTIs and urinary incontinence.
