The 9 best foods to beat the winter blues, end brain fog and stop anxiety | Prof Tim Spector Oct 15, 2026

Show notes

Can what you eat protect your memory, ease brain fog, and lift your mood?

For a long time, we thought the brain was separate from the rest of the body. It's easy to assume that mood, energy, and memory have little to do with what's on your plate.

But in today's episode, one of the world’s leading experts in nutrition, Professor Tim Spector, explains how your gut health shapes your brain health. From low energy and anxiety today to dementia in later years, he shares what to eat to protect your brain throughout your life. Tim shares nine foods to add to your diet - from mushrooms and eggs to tofu and fermented foods - with easy ways to eat more of them, all drawn from his new book, Good Mood Food.

By the end of the episode, you will have learned quick, budget-friendly recipes that support the gut-brain connection and will clearly understand the four principles you need to start boosting brain function today.

What if your tiredness, brain fog, and low mood are linked to the food on your plate? What might change if you ate differently for two weeks?

How to build muscle & stay strong at any age: The surprising links between your gut health, strength training and healthy ageing | Prof Claire Steves & Prof Tim Spector Oct 08, 2026

Show notes

How do you build muscle and stay strong as you age?

For most of us, muscle loss starts in our 30s. It’s easy to think that you can combat this and stay strong into old age by strength training and eating plenty of protein.

Exercise and macros matter, but scientists are uncovering another important piece of the puzzle - a direct connection between your gut health and healthy ageing. It could change how we think about staying strong as we get older.

In today's episode, Professor Claire Steves - a world-leading expert in ageing and health - and Professor Tim Spector explore the gut-muscle axis - how your gut microbiome influences your muscle health. They explain why maximum protein doesn't mean maximum muscle, how gut bacteria ‘talk’ to muscle tissue, and why an unhealthy gut can make muscles resistant to growth.

For listeners looking for simple ways to support their muscles today, this episode includes practical advice you can easily fit into your routine. Claire and Tim share quick daily habits and explain how to get your protein from diverse plant sources.

Could changing what you feed your gut microbes today be the key to keeping your body strong for decades to come?

Most replayed moment: How to stop fighting your body clock | Prof. Debra Skene Oct 06, 2026

Show notes

Every one of us runs on a biological rhythm - a finely tuned system that controls when we feel alert, when we feel tired, and even how we process food.

But here’s the problem: modern life doesn’t always respect this rhythm. Late nights, early alarms, and irregular meals put many of us out of sync with our own biology.

I’m joined by Professor Debra Skene to explain why this mismatch matters, and how you can transform your health by aligning your lifestyle with your internal ticker.

How to eat to lower inflammation - the top 5 foods to boost energy, stop pain, and to live longer | Prof Luke O’Neill Oct 01, 2026

Show notes

Most of us think of inflammation when an ankle swells or a cut turns red. It’s our body’s immune system, and without it, we couldn't fight infections or repair injuries.

But when it stays switched on, this chronic inflammation can drain your energy, can affect your health over the years, and even lead to heart disease. Eventually, 1 in 3 of us will develop an inflammatory disease.

In today's episode, Professor Luke O'Neill - one of the world's top 1% immunologists - explains why that matters and what you can do about it. He explores how everyday foods can push inflammation up, or help calm it. He also explains why balance matters more than banning foods like sugar, red meat, gluten, and dairy. As for your gut, you’ll learn how anti-inflammatory foods like plants, fibre, and a healthy microbiome can help keep inflammation down.

By the end of the episode, you'll know how to eat, rest, and enjoy life in ways that can keep inflammation in check.

Could the way you eat help your body's healer do its job without going into overdrive?
