Let's look at what we eat - from a nutrition research perspective!

Dr. Torsten Bohn, a food chemist and nutritionist heading the Nutrition and Health group at the Luxembourg Institute of Health, shares his insights on what constitutes a healthy diet, the challenges of adhering to dietary recommendations in real life, and the impact of modern dietary trends. We explore the complexities of food bioactives, the significance of the gut microbiome, and how our understanding of nutrition is evolving in light of new research.

Torsten discusses the role of dietary fiber, and how lifestyle factors can influence our overall health. He emphasizes the need for a holistic approach to diet and nutrition, addressing the gaps between scientific recommendations and everyday eating habits. With a keen focus on food security and sustainability, we also touch on the future of food production and the potential of novel foods in meeting the nutritional needs of a growing global population.

As we wrap up, don't miss our pub quiz question that challenges you to consider the role of nutrition in determining lifespan.

What exactly is number theory, and what drives researchers to dedicate their careers to this field? How does this seemingly abstract branch of mathematics connect to the cryptography that secures our digital world?

A couple of weeks ago, Luxembourg hosted the 33rd Journées Arithmétiques, providing us with the perfect opportunity to explore these questions. We sat down with two mathematicians: a visiting researcher and a local expert, offering insights from both international and Luxembourg-based perspectives.

Our first guest is Prof. Jennifer Balakrishnan from Boston University, who led the team that cracked the notorious "cursed curve" problem. We couldn't resist discussing it and learning more from Jennifer about current big questions.

We also explored the mathematical foundations of cryptography with Tim Seuré, a PhD student at the Faculty of Science, Technology and Medicine (FSTM) at the University of Luxembourg, focusing on fully homomorphic encryption.

In this episode, Professor Elisabeth Letellier from the University of Luxembourg and Dr. Mina Tsenkova, now at Amgen in California, discuss colorectal cancer research and ketogenic diet. Mina won the Rolf Tarrach Award 2024 for her PhD thesis.

The discussion centers around the critical role of the gut microbiome in cancer development, specifically how diet influences this relationship. Mina shares insights from her award-winning PhD research on the ketogenic diet and its effects on colorectal cancer, while Elisabeth provides an overview of the disease itself and the rising incidence among younger populations. Together, they explore the complexities of diet, microbiome interactions, and the challenges of translating research into clinical practice.
