Nicole Rose Taylor, our Assistant Head of Undergraduate Courses, headed to RAF Benson to deliver a talk on insulin resistance: The Silent Crisis, at their health and wellness event.

She spoke in place of our much-loved Dean, Heather Rosa, and paused at dawn to honour her before the day began as Heather loved her sunrise walks. 💚

The takeaway? Insulin resistance isn't just a type 2 diabetes issue. It can build quietly for around 20 years before blood glucose shifts on a test, and it's shaped by far more than macros. Sleep and stress play a huge part too.

Thank you to everyone at RAF Benson for the warm welcome and the brilliant conversations.

Day 2 at the British Society of Lifestyle Medicine Conference brought two brilliant ION graduates to the stage.

Yesterday, Debbie Pyke spoke on “Moving Beyond the Myth of the Perfect Diet”, challenging the idea that there’s one “right” way to eat.

Neetha Lobo, one of our most recent graduates, took to the stage at 2pm to present her research on Nutritional Assessment of Diet Quality and Potential Deficiencies in Individuals Using GLP-1 Receptor Agonist Medications — timely work as GLP-1 use continues to grow.

So proud to see our community leading these conversations. Well done, Debbie and Neetha! 👏

A new season is coming 🍂
And we don't just mean Autumn.

Season 5 of the Optimum Nutrition Podcast launches soon, and the ION community gets an exclusive first look at the trailer for our opening episode.

We sat down with Patrick Holford to tackle one of the biggest questions in brain health: is Alzheimer's genetic, or could it be preventable?

Patrick unpacks what's really driving the disease, offers a fresh take on amyloid, explores the role of supplementation, and tells the story of how ION began, from a self-published book sold out the back of a Skoda to the institute that trained you.

📅 Episode launching next week https://www.ion.ac.uk/optimum-nutrition-podcast
