Working title "Impacts of dietary choices on the health of humans, animals, and environment in the Ruhr Metropolis, Germany"

Thesis abstract

Healthier diets that simultaneously promote sustainable food systems are a global concern, which faces a myriad of complexities and difficult challenges. How we are going to achieve that remains the foremost question. One Health is an emerging concept that brings together the health of humans, animals, and the environment, inherent components of the food systems. Many studies have assessed the environmental impacts of diets within nutritional limits using life cycle assessment methodologies. However, performing the life cycle assessment under the One Health is novel. The objectives are to assess the sustainability of survey-based food consumption in the Metropolis Ruhr, Germany, under the One Health approach, and propose optimized diets that promote better sustainability performance within nutritional requirements and local realities. We selected indicators that represent each dimension of the One Health, and that can be integrated in the LCA methodology: a) human health, in terms of dietary risk factors attributed to diet-related non-communicable diseases; b) ecosystem health, in terms of environmental impact categories; and c) animal health, in terms of animal welfare loss from farm to slaughter. We based on the nutrition-environmental LCA, which integrates nutritional quality and environmental impact assessments and integrated animal welfare indicators. We proposed improved diets according to better nutritional, health, environmental, animal welfare performance by balancing food items that at the same time, adequate to sustainability constraints and are within the nutritionally recommended limits. The diets collected through the food frequency questionnaire will be defined into diet groups. The food items of each diet will be grouped following the food basket principle. Results will show the impacts of the food basket of each diet group on the eight selected environmental impacts at the midpoint level, on the animal welfare based on the three indicators selected, and on the dietary risk factors attributed to three diet-related non-communicable diseases. Based on the results, an optimized diet will be designed by constraining the impacts within the German nutrient reference values, and it will involve the local community in the process.
