Dietary intake and environmentally sustainable diets

This programme focuses on food security, particularly investigating the balance between healthy eating and minimising the environment impact of the diet, often referred to as sustainable diets.

The aim of the research is to increase our understanding of the balance between health and the environmental impact of the diet and explore people’s perceptions, opinions and willingness to adopt a more sustainable diet. The research to date has focused on climate change and greenhouse gas emission but this is being extended to include other environmental factors, such as land use requirements.

We are also investigating wider aspects of eating behaviours and determinants of food choice among the general population.

Research focus

Jennie is a Professor in Sustainable Nutrition and Health in the Public Health Nutrition Research group.  Her main research interest focuses on a new area of research relating to food security exploring dietary choices combining need for environmental sustainability within the diet with dietary recommendations for health. With global climate change and the recognition that dietary choices can have a significant impact on the environment, it is important to understanding what sustainable diets means in terms of the food choices we should be making for health, climate change (e.g. reduction of greenhouse gas emissions, water and land use), social and ethical reasons.  The aim of this research programme is to bring together these different elements of sustainability to give a greater understanding of the synergies and conflicts in terms of dietary intake and explore some of the attitudes and barriers to dietary change of consumers.   

Some of her previous research focused on methodology for the evaluation of community based nutrition related policies and interventions. With the high prevalence of obesity there is a greater need for community based (e.g. schools, workplaces) nutrition and physical activity initiatives to address this problem. The impact of national and local nutrition related public health policies on changing dietary behaviour and improving health remains unclear and part of the research programme was to develop evaluation framework for nutrition related policies and interventions.  Underpinning all this research is understanding dietary behaviours and the barriers to changing lifestyles.
