Mathilde Touvier, a researcher in nutritional epidemiology, won the 2021 Bettencourt Prize Coups d'Élan pour la recherche française for her work on how ultra-processed foods affect health.

You are what you eat

Diet is one of the main factors influencing our health. Some changes in eating habits that have occurred in recent decades, such as the increase in the consumption of ultra-processed products, raise questions about their impact on human health at the global level.

Ultra-processed foods are foods that have undergone one or more physical, chemical or biological transformations, or that contain various additives. They’re often in our cupboards! Dr. Touvier's team has helped to uncover a link between the consumption of these foods and possible negative health effects. Now she is trying to understand how different facets of ultra-processed foods (the degree of processing, additives alone or in combination, packaging contaminants) affect long-term human health.

A large-scale epidemiological study

Dr. Touvier and her team are closely monitoring the eating habits of 171,000 people in the NutriNet-Santé study to study the relationship between diet and health. The data gathered for each individual (including product consumption frequency, brand and cooking method) is complemented by urine, feces and blood samples. The epidemiological study uses relevant analytical methods to determine correlations between different aspects of ultra-processed foods and health, with a particular focus on cancer, obesity and cardiovascular disease. Additional cell or animal studies will be conducted to establish cause and effect relationships.

This is the first research program to address the issue so comprehensively. It could have a direct impact on consumer choices, the food industry and health authorities to guide the development of public health policies.

The foundation’s support

The Bettencourt Prize Coups d'Élan pour la recherche française will contribute to the team’s research by allowing them to adapt their computers, data storage and work space to their needs.

Mathilde Touvier in a few words

Mathilde Touvier is an agricultural engineer specializing in human nutrition. After a PhD in epidemiology in Nancy in 2006 and two post-doctoral fellowships, in 2010 she became an Inserm researcher on the Nutritional Epidemiology Research Team (EREN) in Bobigny.

The EREN team, which she has led since 2018, is the only research team in France focusing entirely on the epidemiology of nutrition and health, and one of the few in the world. The team studies the link between nutrition and health and its underlying mechanisms to understand what drives eating behavior. They have coordinated and tracked the NutriNet-Santé cohort since 2009.  

Throughout her career, many French and international organizations have called upon Dr. Touvier for her expertise in nutritional epidemiology. She is also involved in coordinating the National Cancer Research Food Network (NACRe) and has just been elected to represent France on the the Scientific Council of the WHO’s International Agency for Research on Cancer (IARC).

Bettencourt Prize Coups d'Élan pour la recherche française

The Bettencourt Prize Coups d'Élan pour la recherche française was created by the Foundation in 2000. It has rewarded 78 French laboratories and more than 900 researchers have benefited from this prize. Until 2021, this prize was awarded each year to four research teams, from Inserm and the CNRS Institute of Biological Sciences. The amount of the prize endowment was 250,000 euros per laboratory.
