Supermarket shelves are full of foods promising to be healthy: high-protein, low-fat, gluten-free, sugar-free. How do you know what's true? 

Today, Professors Tim Spector and Sarah Berry, world-leading experts in nutrition and diet, share the six rules they use for their own weekly grocery shopping. They cover which food labels are worth trusting and which are just marketing scams, how to make snacking a part of a healthy diet, and why your daily staples, like bread, matter more than the occasional treat.

By the end of this episode, you'll know exactly what to reach for on your next shop, and what to leave on the shelf.

How many "healthy" scams are sitting in your basket?

From smartwatches to fitness trackers, more of us than ever are monitoring our health in real time. With just a glance at our wrist, we can check our step count, sleep quality, heart rate and, more recently, something called HRV.

But what do these numbers actually mean? And more importantly, how can we use them to improve our lives?

I’m joined by Dr Malcolm Finlay to break down the data behind the devices. He explains how to turn confusing metrics into meaningful action. helping you adjust your training, manage stress, and make smarter decisions for your health.

Most replayed moment: What your wearable is really telling you | Dr Malcolm Finlay

Picture the sound of a bone snapping - the kind of sound that makes you wince - and ask yourself how often you’ve thought about your bone health.

Most of us only think about bone density when something breaks. Until then, your bones stay almost invisible, carrying you through every day.

In today’s episode, Professor Elaine Dennison, a world-leading expert in bone health, explains why that needs to change, why stronger bones are key to living more healthy years, and why declining bone health isn’t inevitable. Elaine explains why it’s not just about avoiding broken bones, but about learning to understand one of the most important living tissues in your body.

By the end of the episode, you’ll know exactly how to protect your bones so they can look after you now and for many years to come.

Could your bones be the missing anti-aging link you’ve been missing?

Is your gut the secret to anti-aging? 6 science-backed ways to boost your bone strength, muscle, and balance | Prof Elaine Dennison

We’ve all heard the saying: Breakfast is the most important meal of the day. And while it may sound like a cliché, there’s some truth to it. Because for many of us, breakfast is the one meal we keep the same - day after day, morning after morning. 

This consistency means our breakfast choices have a powerful influence on our long-term health.

So, today I’m joined by Tim Spector and behaviour expert Professor Ben Gardner to share practical ways to break out of unhealthy routines and build a breakfast habit that will support you every single morning.

Most replayed moment: How to build a better breakfast | Prof. Ben Gardner & Tim Spector

Are some of your "healthy" foods actually high-risk ultra-processed foods? 

For decades, nutrition advice seemed relatively straightforward. Eat less sugar. Less salt. Less saturated fat. Then it all fell apart.

In today’s episode, we examine the research that has forced us to rethink what makes food harmful in the first place. Two of the world’s leading nutrition scientists, Professor Tim Spector and Professor Sarah Berry, tell their own story of why they’ve changed their minds about it.

We explore why sugar, salt and fat aren’t the whole story, explain why ultra-processed foods are making us sick, and share groundbreaking insight that only a small portion of them are really harmful.

By the end of the episode, you’ll know what to watch out for and what to worry less about when you’re food shopping.

Next time you reach for a "healthy" yogurt or a quick pasta sauce, would you still choose it if you knew exactly how it was made?

Floating through all of our bodies is a complex network of hormones. You can think of it as an internal postal service, delivering vital messages and instructions to different organs and systems.

But what happens if these messages get intercepted, mixed up, or worse, not delivered at all?

In this episode, Dr Andrew Jenkinson tells us about a hormone that plays a crucial role in weight regulation and the undesirable consequences when it isn’t functioning properly.

He also shares three simple tips you can do tomorrow to make sure your hormones support your health.

Most replayed moment: The hormone that controls your weight | Dr Andrew Jenkinson

Growing up, many of us were taught to just stay calm and carry on - as if stress was all in the mind, with no real effect on the body. But chronic stress can change your brain, raise your risk of heart disease, and even shorten your life. 

In this episode, we ask: what happens when a stress response built to last minutes never switches off?

Today, Professor Carmine Pariante, one of the world's leading researchers on stress, helps us understand what’s happening in your body during a stressful moment and why chronic stress disrupts sleep, appetite, and energy levels. Carmine also explains how worried you should be about cortisol, and whether "cortisol face" and "cortisol belly" are backed by evidence.

By the end, you’ll understand why stress can be so powerful, when it becomes harmful, and have some evidence-based ways to manage it.

Next time you reach for wine, your phone, or something sweet after a hard day, ask yourself: is this helping you cope, or helping you avoid how you feel?

Today we’re talking about gut microbes.

Professor Tim Spector often refers to the microbes in our gut as ‘mini pharmacies’. This is because they provide us with powerful chemicals that help support our health.

But not all gut microbes are on our side. In fact, there’s an ongoing battle in our digestive system between the beneficial bugs and those that wish to do us harm.

I’m joined by Tim Spector and microbiome researcher Nicola Segata join me to explore this microscopic war, and explain how simple changes to your diet could help tip the balance toward the good guys.

Most replayed moment: The hidden battle inside your gut | Tim Spector & Nicola Segata

Is fat good or bad for your heart? For decades, we blamed fat and cholesterol for clogged arteries and heart attacks. Now you choose low-fat yogurt to protect your heart, while others cook with beef tallow.

In this episode, Dr. Alice Lichtenstein, a world-leading expert on dietary fat and heart health, helps settle the debate.

Dr. Lichtenstein explains which fats protect your heart and which to cut back on, you'll learn what raises your cholesterol, and why the type of fat you eat matters more than how much of it you eat. You’ll leave the episode with some practical food swaps to protect your heart and live longer.

Have you swapped butter for "low-fat" alternatives loaded with sugar? Could that choice be working against your heart?

The 5 best food swaps to lower cholesterol, protect your heart and to live longer | Dr. Alice Lichtenstein

Today we’re talking about the immune system.

It’s one of the most important systems in our body, yet it’s also one of the hardest to understand. You can’t see it, you can’t feel it working, and there’s no simple way to measure whether it’s strong or weak.

But when it fails, we certainly notice.

Everywhere we look, supplements and superfoods promise to ‘boost’ our immune system. But how many of these claims are actually supported by science?

Professor Daniel Davis joins me to explain how our immune system truly works, and what the evidence says is the best ways to support it.

Today, we’re talking about Omega-3.

Omega-3 fats have been celebrated, scrutinised, and debated for decades. While some research points to remarkable heart health benefits, other studies suggest they can actually raise the risk of cardiovascular disease.

So where does the science stand today? Should we supplement, rely on food, or rethink our approach to omega-3 completely?

Dr. Bill Harris and Professor Sarah Berry join me to cut through the confusion, explain omega-3’s role in the body, and share an evidence based approach to this fascinating fatty acid.
