Research interests
Most of her research is within epidemiology and is based on large population-based studies such as the Norwegian Women and Cancer study and the Tromsø Study. She also has extensive experience working with data from the SAMINOR study, the Dental Health in the North study, and the European Investigation into Nutrition and Cancer (EPIC).
Vitamin D and health has been her area of expertise for more than two decades, and she has been recognized and consulted as an expert in this field both nationally and internationally in various contexts.
One of Magritt's current main interests is preparedness and food security from a public health perspective, particularly related to the situation in the Northern region. She leads a comprehensive, multidisciplinary Research Council-funded project on food preparedness and public health in Northern Norway called Resilient North.
She also conducts a clinical controlled study on vitamin D and periodontitis and collaborates on oral health projects with the Public Dental Service Competence Centre of Northern Norway, where she holds an adjunct appointment.
Her research interests can be listed as follows:
- Nutritional Preperedness
- Preperedness and public health
- Nutritional Epidemiology
- Nutrition and Cancer
- Vitamin D in health and diseases
- Nutrition and health in the Arctic population
- Nutrition and health in the Sami indigenous population
- Oral health
Teaching
Magritt Brustad is a Professor in Nutritional Epidemiology and serves as the academic unit leader for Nutrition at the Department of Community Medicine, Faculty of Health Sciences, UiT.
From 2021 until August 1, 2025, she was the leader of the Bachelor’s in Nutrition and Master’s in Clinical Nutrition programs, responsible for their daily operations, strategic development, and representation in relevant local (UiT) and national forums. She supervises Ph.D. and Master’s students.
For the 2025/2026 academic year, she is on a research sabbatical (FoU-termin) and therefore has no teaching obligations during this period.
