As a first-time attendee at the International Congress of Nutrition 2025 in Paris, I found myself immersed in a vibrant exchange of ideas that stretched far beyond borders. The theme, “Sustainable Food for Global Health,” set a powerful tone for an event rich in scientific discovery and inspiration from all corners of the globe.
Global Challenges Resonating Across Sessions
One thing was clear: nutrition science, no matter where it’s practiced, is grappling with shared methodological challenges. During sessions, debates surfaced repeatedly around the problems of dietary assessment—how do we reliably measure what people eat? The hurdles are universal and hearing how researchers from different regions are addressing them underscored how collaborative solutions could drive real progress.
The difficulties don’t stop at data collection—in the realm of publishing, speakers and attendees spoke candidly about a lack of reviewers, steep publication costs, and the complexities of accessing vital research. Bernard Corfe’s lecture on the “Challenges in publishing in nutrition science and some opportunities too” offered a nuanced, deeply thoughtful perspective, reminding us that the science of nutrition is shaped as much by logistics and infrastructure as by experimental design.
Open Science: Data Repositories & Open Access
Conversations about data repositories and open access were equally compelling. There’s growing enthusiasm—especially among early-career researchers—for platforms that ensure shared, accessible datasets and publications. The promise of open science felt like a pivotal tool to foster transparency, build trust, and accelerate progress collectively.
Culture Counts: Designing Inclusive Interventions
What struck me most was how consistently cultural context was woven into every discussion about interventions. Whether addressing non-communicable diseases or crafting public health strategies, there was a shared understanding that cultural relevance isn’t optional—it’s essential. Designing programs that resonate with food traditions, local norms, and community valuesis central to long-term success.
Voices from Across the Globe: Food Systems & Innovation
ICN 2025 was a masterclass in global learning. Listening to thought leaders—from seasoned professors to grassroots innovators—offering bold visions for food system transformation was invigorating. Sessions spanned the future of nutrition recommendations, non-communicable disease prevention, and even the intersection of gastronomy and life quality. The sheer diversity of perspectives—emerging voices from low- and medium-income countries, policy experts, academics, and researcher-practitioners—embodied the potential of collective insight to spark real change.
Why It Mattered
For me, at my first ICN, this conference reaffirmed how much richer—and more impactful—our work becomes when we center global voices, acknowledge real-world constraints, and design with culture in mind. From methodological transparency and open science to food system-level innovation—this event was a vibrant invitation to think bigger, together.
