Here’s a bold statement: One professor’s journey to shape public health policy is about to inspire you to rethink the impact of scientific expertise. Meet Professor Sue Lanham-New, whose groundbreaking work in human nutrition has left an indelible mark on the UK’s health landscape. But here’s where it gets fascinating: her role as a member of the Scientific Advisory Committee on Nutrition (SACN) within the Department of Health and Social Care (DHSC) isn’t just about titles—it’s about transforming lives through evidence-based recommendations. And this is the part most people miss: how a single voice, backed by rigorous research, can redefine national health guidelines.
Professor Lanham-New, a distinguished Professor of Human Nutrition at the University of Surrey, joined SACN in June 2010, driven by its reputation for excellence and her own passion for bridging the gap between nutrition and public health. Her research, centered on the interplay between nutrition, bone health, and vitamin D, has been nothing short of revolutionary. But here’s the controversial bit: while many focus on macronutrients like protein and carbs, Sue’s work highlights the often-overlooked role of micronutrients like vitamin D—a perspective that has sparked debates in the scientific community.**
What inspired her to join SACN? As a doctoral student, Sue relied on the recommendations of SACN’s predecessor, the Committee on Medical Aspects of Food and Nutrition Policy (COMA), as a cornerstone of her research. When the opportunity arose to join SACN, she saw it as more than a career move—it was a chance to give back. Her goal? To ensure that every recommendation was not just evidence-based but also in the public’s best interest. And this is where it gets personal: Sue’s critical thinking and enthusiasm have made her a ‘critical friend’ within the committee, challenging assumptions while fostering collaboration.
Her impact? Tangible and far-reaching. As part of SACN’s Vitamin D working group, Sue played a pivotal role in establishing new intake recommendations that have since become a cornerstone of public health policy. Here’s the kicker: before her work, the UK had no reference nutrient intake (RNI) for vitamin D. Her efforts didn’t just fill a gap—they created a paradigm shift. But here’s the question that divides opinions: Are we doing enough to prioritize micronutrients in public health campaigns? Sue’s work suggests we’re only scratching the surface.
Collaboration has been a hallmark of Sue’s experience. Working alongside Chief Scientific Advisers and multidisciplinary teams, she’s gained insights into areas beyond her expertise, enriching her own research. She credits the SACN secretariat for their ‘phenomenal’ support, ensuring the committee’s seamless operation. And this is the part that’s often overlooked: behind every successful advisory body is a team of unsung heroes making it all possible.
For academics looking to make a difference, Sue’s advice is simple yet powerful: ‘The door won’t open if you don’t knock on it.’ She encourages observing committee meetings, getting involved in diverse advisory groups, and actively seeking opportunities. Reflecting on her journey, she emphasizes the privilege of influencing policy: ‘You will learn so much, and you can make a difference.’
Now, here’s the thought-provoking question: In an era of information overload, how can we ensure that scientific expertise like Sue’s reaches those who need it most? And more importantly, are we willing to challenge established norms to prioritize public health? Share your thoughts in the comments—let’s spark a conversation that matters.
