Diet, lifestyle and genetic susceptibility

Every day, each Dane consumes an average of 3 kilograms of food and fluids, which amounts to a ton each year. Food consumption habits have both health and environmental consequences. In the research group, we study associations between diet, lifestyle and health. The main outcomes we focus on are obesity, cardiovascular disease and cancer, both in one generation and across generations in families. Increasingly, we also study the interplay between food consumption, environmental impact, and health.

Research areas

Applying novel methods to assess associations between diet and health
Modelled substitution of foods
Socioeconomic determinants of food and drink habits
Associations between diet, lifestyle and obesity exposures in one generation, and health outcomes in the next
Environmentally sustainable foods or dietary habits and health
The interplay between genetic variation, diet, and health
