Introducing The truth behind memory loss - and how to stop it with exercise | Dr. Wendy Suzuki from ZOE Science & Nutrition.

Follow the show: ZOE Science & Nutrition

We spend so much time focusing on how exercise changes our bodies - burning calories, building muscle, shedding fat. What if the most important transformation is happening where you can’t see it? Hidden inside your skull, your brain is changing with every step, squat, and sprint.

Neuroscientist Dr. Wendy Suzuki has spent years uncovering how movement rewires the brain. As a professor at NYU and an expert in neuroplasticity, Wendy’s research reveals how aerobic exercise boosts memory, sharpens focus, and even builds a protective barrier against dementia.

In this episode, Wendy explains what happens inside your brain when you move, why it’s never too late to strengthen your mind, and the powerful ways exercise can slow brain aging. You’ll discover simple, science-backed habits - including her own brain-boosting routine - to help you stay mentally sharp for years to come.

Introducing 5 years after COVID, what did we learn? | Dr. Tim Spector from ZOE Science & Nutrition.

Follow the show: ZOE Science & Nutrition

The COVID-19 pandemic is in the rear-view mirror, so what did we learn about mask wearing, vaccines and prevention? And how can you stay healthy to face a future pandemic?

Professor Tim Spector, one of the world’s top 100 most cited scientists, looks back on the pandemic and what we learnt about symptoms, transmission and vaccines in the early stages. We’ll reflect on ZOE’s role - collecting data from millions of people on their symptoms, identifying COVID hotspots and shaping public understanding of the virus.

Then we discuss the possibility of the next pandemic, and how we can individually protect ourselves against it. By the end of this episode, listeners feel more equipped to stay safe in the face of another global pandemic.
