Food, Global Health

The food we eat occupies a central place in our lives and affects our health. Even though major advances have been made over the last decades, malnutrition is still a global problem. It can result from such factors as famine, nutrient deficiencies, excessive body mass, and obesity. If we wish to deal with food and health challenges, it is important to understand our dietary choices, our dietary regimes, the composition of the foods we eat, and inequalities in our access to food. At INRAE, our research examines food healthfulness and nutritional quality and explores the biological, economic, and cultural factors that affect our diets. The goal is to understand the links between human health, food, and the environment to improve the sustainability of food production, food health benefits, and the accessibility of healthy diets.

Food at the heart of our health

Our health is strongly tied to the health of plants, animals, and the environment

There are many relationships between food, the environment, and human health. To better understand them, we study food consumption patterns and dietary patterns, which are controlled by multiple other factors that are physiological, psychological, economic, and cultural in nature. We also explore how our health is affected by the characteristics of the food we eat. These characteristics depend on how crops and livestock are farmed, which influences the nutritional composition and healthfulness of the resulting food products. They also depend on transformation and storage methods, which can affect food quality (e.g., nutritional quality, presence of additives and/or contaminants). In tandem, food production and transformation processes can result in the release of toxic substances into the soil, air, and water, which can also impact our health. It is therefore important to take a broader view of health, given that the health of humans is strongly tied to the health of plants, animals, and the environment as well as pollution levels in the soil, air, and water. When we talk about "one global health," this is what we mean.

This diversity of mechanisms means that there are a diversity of stakeholders involved (crop farmers, livestock farmers, manufacturers, distributors, and consumers), who each make market-based decisions that are also influenced by different types of public policies (e.g., related to agriculture, food, health, and the environment). It is thus crucial to improve our understanding of each of these mechanisms, as well as to adopt a more integrated perspective, if we wish to arrive at innovative solutions, inform public policies, guide future dietary transitions, and manage health in a more global way.

INRAE 2030

Promoting a global approach to health

epl betting odds

This is the 4th scientific priority of the INRAE 2030 strategic plan. Our goals are to study:

  • emerging and re-emerging infectious diseases that move within and among environments, agricultural systems and food production systems
  • pollution, contaminants, and the exposome
  • preventive nutrition for improved human and environmental health

INRAE's 2030 priorities


Our research explores diets from early childhood to adolescence and adulthood, eating behaviour, the gut microbiota, links between diet and chronic diseases, toxicology, and new food development. With regard to animal health, we study zoonoses that are passed from animals to humans, such as the flu, as well as prion and infectious diseases.

PREZODE, an international initiative to prevent future pandemics

epl betting odds

PREZODE was announced on the occasion of the One Planet Summit for biodiversity held on 11 January. Three French research institutes - INRAE, CIRAD and IRD – teamed up with around ten other research bodies in France, Germany and the Netherlands to launch PREZODE. This worldwide programme will combine research and practical steps. It was shared in December 2020 with more than 400 participants from 50 countries on 5 continents with the goal of open co-construction. International organisations like the WHO, OIE, FAO, UNEP, the World Bank and European Commission have all expressed keen interest in the initiative.
