Medical Evidence Matters with Liz Tucker (formerly known as What Your GP Doesn't Tell You) was a finalist in the recent 2024 Independent Podcast Awards. This fortnightly podcast reveals the stories from the world of medicine that others don’t, won’t or only very partially report. Aimed at both doctors and the public, it’s hosted by award winning medical journalist and former BBC producer Liz Tucker, who reports not just on the science but on the finance and money that can impact it. Liz asks what does the medical data actually tell us and why is this often interpreted and presented very differently? How do we know what information to trust and when should we ask our GP, but what’s the evidence?

Personalised Nutrition: How It Is Transforming Our Understanding of Food

Episode 46

Tuesday, August 20, 2024 • Duration 01:06:05

Professor Sarah Berry discusses her research in personalised nutrition, which is uncovering the hugely varied effects different foods may have on one particular group or individual compared to others. This variability can be due to our genetics, metabolism or a number of other factors.

This may well have important implications for what, when and how we should eat.

For example, research is revealing that as we age, many of us have a worse tolerance for eating carbohydrates in the evening compared to earlier in the day. And while some blood markers have a strong genetic effect, many others can be heavily influenced and changed by lifestyle.

Professor Sarah Berry is a nutrition scientist based at King’s College, London University. She has particular research interests in individualised nutrition, food and fat structure, and the metabolic changes that happen after eating. She is also the chief scientist for the nutrition company Zoe.

Why Your Oral Microbiome Is Critical For Good Health

Episode 45

Tuesday, August 6, 2024 • Duration 47:18

Dentist Dr Victoria Sampson argues that while the gut microbiome gets a huge amount of attention, funding and publicity, the oral microbiome gets almost entirely overlooked, yet it is essential to our health.

As she explains in this podcast, it has a close symbiotic relationship with our gut biome, so changing the composition of one affects the other. And perhaps most importantly of all, poor oral biome health is linked to a range of illnesses from heart disease and Alzheimer's to diabetes and arithitis.

Remarkably even our fertility can be affected by the health of our mouth. But the oral biome is usually disregarded as a possible cause or aggravating factor in all of these conditions.

So what can we all do to ensure that we have a healthy oral biome?

Dr Victoria Sampson is a co-founder of the Health Society.

In addition to all the standard dental services, the Health Society also offers oral diagnostic testing. And anyone wantting to join the waiting list for a new oral microbiome test which will shortly be available can do so here.

The Secrets To A Successful Keto Diet

Episode 36

Tuesday, March 5, 2024 • Duration 54:36

Beth Zupec–Kania is a dietician and nutritionist, who has spent over 30 years developing very low carb - otherwise known as ketogenic diets - to treat a range of both physical and mental health conditions. She has worked with many of the leading neurologists and psychiatrists pioneering this field.

I heard Beth speak at a conference Metabolic Psychiatry: Understanding How Modifying Metabolism Can Create Mental Health last November. I was very keen to get her on the podcast, because I’ve now done several episodes about the use of ketogenic diets to treat different illnesses. And so many people have asked me about the practicalities of following this dietary approach, so Beth seemed the perfect guest to discuss these issues.

She explains her particular keto strategy. Critical to this is transitioning slowly to avoid what is sometimes known as "keto flu"; the role of medium chain trigleride oils, MCT for short; and the inclusion of Beth's own specially designed smoothie recipe. The podcast will be making Beth's recipe available to all mailing list subscribers a week after the podcast has gone live.

Should You Take A Weight Loss Drug?

Episode 35

Tuesday, February 20, 2024 • Duration 49:57

Dr Barbara Mintzes and Dr Joel Lexchin, have recently published a review paper on the weight loss drug Wegovy (generic name semaglutide). They discuss it and the new generation of similar obesity medications.

The hype surrounding this new class of drugs has been huge, but is it justified?

These pharmaceuticals are called glucagon-like peptide 1 agonists or GLP-1 for short. They work by stimulating cells in your intestines to release a natural hormone called GLP-1 that tricks your stomach and your brain into thinking you’ve just eaten a large meal.

Clearly, obesity is major problem in countries across the world, but as Barbara and Joel reveal although these drugs do achieve a significant weight loss, weight gain is common once the medication is stopped.

And like any drug there are side effects, common ones include headache, vomiting, diarrhoea, and constipation. Rare reported side effects include pancreatitis and increased heart rate. Currently, the European drug regulator, the EMA is reviewing data on the risks of thoughts of suicide and self-harm associated with GLP1 medicine. It is analysing around 150 reports. It expects to report on its findings this year.

So exactly what are the risks and the benefits of these drugs, and who should take them?

Deprescribing from Psychiatric Drugs: The Problems and the Solutions

Episode 34

Tuesday, February 6, 2024 • Duration 55:43

Dr Mark Horowitz discusses why psychiatric medication has turned out to be far harder to stop than any one expected.

For Mark, this is as much a personal as well as a professional interest. For as a patient, at one point he was taking five different psychiatric drugs. Ironically, although Mark was working in London at the Institute of Psychiatry, he found the mostly useful information about deprescribing came - not from the medical profession - but from peer support websites.

This experience has driven his research and interest in safely stopping psychiatric medication. He, along with Professor David Taylor, has just written a new handbook The Maudsley Deprescribing Guidelines, providing step-by-step instructions on how to effectively stop all commonly used antidepressants, benzodiazepines, gabapentinoids and z-drugs.

One of the key findings from this work, is that it is essential to taper off the drugs much more slowly than patients have previously been advised. And perhaps most surprising of all, is how a small amount of medication can have a completely disproportionate effect. In some cases, a 1mg dose can have nearly half the effect of a 20 mg dose, which means patients may have to taper far more gradually as they move down to smaller and smaller amounts of a drug. A process that may need to take months or even years.

The Maudsley Deprescribing Guidelines: Antidepressants, Benzodiazepines, Gabapentinoids and Z-drugs (The Maudsley Prescribing Guidelines Series) by Mark Horowitz and David Taylor, published by Wiley-Blackwell will be available from 15 February 2024.

Could Changing Your Diet Improve Your Mental Health?

Episode 33

Tuesday, January 23, 2024 • Duration 58:13

Psychiatrist Dr Georgia Ede argues that the medical profession has completely underestimated the huge impact of diet on our mental health.

In her new book, Change Your Diet, Change Your Mind, Georgia reveals improvements we can all make to our diet, and in particular, three different dietary approaches for those looking to improve their mental health.

She suggests that early results from a range of trials using this approach to treat conditions from bipolar disorder to schizophrenia, show a much great effect, in fact 6 to 10 times that seen in any comparative drug trial.

Georgia believes a metabolic evaluation should be standard practice for every patient seeking psychiatric help.

In her own practice, this approach has enabled her to reduce the medication many of her patients take and in some cases allowed them to come off all medication all together.

Ironically, the psychiatric drugs used to treat many of these mental health conditions, which Georgia argues can also be useful, can at the same time actually worsen metabolic health, which can then negatively impact brain health.

So just how does a psychiatrist - or indeed any doctor - balance the benefits and risks of treatment?

Change Your Diet, Change Your Mind by Georgia Ede is due to be published by Yellow Kite books on 30th January 2024.

Treating Long Covid

Episode 32

Tuesday, January 9, 2024 • Duration 43:03

Dr Lisa Sanders, writes a column called Diagnosis in the New York Times magazine, which was the inspiration for the Fox medical drama House, M.D. .The show in which Hugh Laurie, playing Dr Gregory House, regularly managed to diagnose the most obscure of medical conditions.

But today Lisa has arguably a rather tougher challenge than Hugh Laurie ever faced, she’s recently become the Medical Director of Yale's Long Covid Multidisciplinary Care Center. Long Covid can affect multiple systems and organs in the body, and finding effective treatments so far has proved extremely difficult.

However, Lisa reveals several approaches that it does appear can help at least some patients.

She argues that we need to see long covid not as entirely new phenomenon, but in the context of many other post-acute infection syndromes such as ME/CFS or flu. Controversially, Lisa suggests that it needed enough doctors to get sick from long covid for the profession to start taking these syndromes more seriously.

What Doctors Don’t Get Taught

Episode 31

Tuesday, December 12, 2023 • Duration 57:32

Dr Robert Lufkin argues that modern medicine hasn’t paid nearly enough attention to the underlying causes of diseases, and has tended to treat symptoms instead.

And in a controversial new book Lies I taught at Medical school, How Conventional Medicine is Making You Sicker and What You Can Do to Save Your Own Life, published by BenBella books, as evidence for his claims, he points to the epidemics of chronic disease, we are now seeing in the industrialised world.

In the US in 2010, 16-21% of adults had two or more chronic diseases. Today, shockingly, the figure is 40%.

Rob explains what needs to change and why he believes medical teaching gets a number of pivotal facts so wrong.

Thalidomide - The Story You Don’t Know (Part Two)

Episode 30

Tuesday, November 28, 2023 • Duration 48:39

This is the second episode of a two parter about a new investigation into the drug thalidomide, so if you haven’t listened to part one, please do go back and listen to that first.

Thalidomide is one of the greatest medical catastrophes of the 20th century. It’s now thought to have been responsible for around 100,000 miscarriages and disabled children.

In this episode, journalist Jennifer Vanderbes reveals the second half of the story. The result of six years of research, resulting in her recent book: Wonder Drug: The Hidden Victims of America’s Secret Thalidomide Scandal.

After thalidomide’s launch in 1957 by the Germany company Chemie Grunenthal, four years on, doctors in a number of countries, are becoming increasingly concerned about the drug’s effects.

In Australia obstetrician, Dr William McBride, having delivered several disabled babies in mothers who were given thalidomide, starts to conduct animal experiments and becomes convinced the drug is linked to the disabilities he is seeing.

While in Germany, geneticist Dr Widukund Lenz's analysis of babies whose mothers have taken thalidomide, produces what he believes is a clear evidence that the drug is very far from safe. The devastating disabilities being caused in new born babies, include a shortening or absence of limbs; hands and feet that don’t fully form; and damage to ears, eyes, brain, skeleton and internal organs.

So the pressure to take the drug off the market grows.

And in the States, further children will be harmed as unbeknownst to the FDA, the drug has been dispensed by over one thousand doctors. This is despite the fact that it has not been approved for use, a development which will add further heartbreak to the tragedy. In total, Vanderbes estimates that five million doses of thalidomide were distributed in America.

Jennifer Vanderbes Wonder Drug: The Hidden Victims of America’s Secret Thalidomide Scandal is published by Harper Collins.

Thalidomide - The Story You Don’t Know (Part One)

Episode 29

Tuesday, November 14, 2023 • Duration 50:06

It was one of the greatest medical tragedies of the 20th century.

In 1957, a new wonder drug was launched in Germany. It was marketed as an astonishingly safe sedative. Tragically, this could not have been further from the truth. For this was the drug thalidomide, and it would end up being responsible for around 100,000 miscarriages and disabled children.

This week’s guest, journalist Jennifer Vanderbes, in a forensic six year investigation has uncovered compelling and shocking new information about warnings that went unheeded, test results that were misrepresented, and uncovered scores of potential victims who have never before been recognised as harmed by the drug.

One of the heroines of this narrative is a dogged and committed FDA reviewer Dr Frances Kelsey, who sceptical of the drug never approved it for US use. However, as Vanderbes reveals in her new book: Wonder Drug The Hidden Victims of America’s Secret Thalidomide Scandal, published by Harper Collins, although the drug was never sold in the states, the medication was sent out to 1,200 doctors to be used in what were termed clinical trials. These physicians then passed on thalidomide to other colleagues.

But the FDA later described these not as a clinical trials - but a marketing scheme. Which as Jennifer reveals, means, tragically, there are also American babies born with birth defects likely to have been caused by thalidomide.

Had early safety signals been acted on or investigated, thousands of families and babies could have been spared unbelievable heartbreak.
