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.
