I’m an associate professor at the Department of Medical Epidemiology and Biostatistics (MEB) at Karolinska Institutet and professor in public health at the Division of public health science at Mälardalens University. Moreover, I was a visiting scholar at Stanford School of Medicine during the academic year of 2015-16. The focus of my research is sustainable lifestyle and health.
We recently published a study on diet-related greenhouse gas emissions and it is one of the first published papers based on the LifeGene study: Bälter K, Sjörs C, Sjölander A, Gardner C, Hedenus F, Tillander A. Is a diet
low in greenhouse gas emissions a nutritious diet? - Analyses of self-selected diets in the LifeGene study. Arch Public Health. 2017 Apr 10;75:17. https://archpublichealth.biomedcentral.com/articles/10.1186/s13690-017-0185-9.

My research focus on sustainable lifestyles and health. This includes a lifestyle that promotes overall good health and quality of life but also contributes to a sustainable development. Sustainable development means that we can meet our needs in terms of living conditions and resource utilization, without jeopardizing future generations' ability to meet their needs. For example, climate change is a global problem and proactive steps are necessary and my research is therefore grounded in the sustainability goals by the United Nations, i.e. agenda 2030. Approximately 25 percent of the global greenhouse gas emissions originate from the production and distribution of food but different food products generate different amounts of emissions. Changes in food consumption and other lifestyle factors will be important to reduce emissions, but may also be of great public health relevance and thus, the overall aim of my research is to study the how a sustainable lifestyle may promote heath and reduced emissions of greenhouse gas emissions using epidemiological data.
