Clients are presenting with increasingly complex health needs, and keeping up with the evidence while running a busy practice isn't easy. That's why we're developing a new suite of advanced professional practice courses, designed to help nutrition practitioners deepen their expertise, meet their CPD requirements and grow their confidence in practice.

Flexible, online and built around real clinical practice.

Join Balens for a webinar for ION students about to graduate, graduates and practitioners. We'll break down the core insurance protections every practitioner needs, show how cover works in real-world scenarios, and share claims insights to help you reduce risk and respond with confidence if something goes wrong.

Expect clear examples of what a practitioner policy typically includes, and how different liabilities work together to protect your practice, your clients and your reputation.

Hosted by Annie Tabberner (Client Engagement Representative) and Katie Thomas (Technical Schemes Manager) at Balens, with a live Q&A at the end.

🗓 Thursday 8 October

Fasting has gone from ancient ritual to modern research topic, and practitioners need to know what the evidence actually says.

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.
