Research Focus

Kristina Petersen's research is focused on the efficacy and effectiveness of dietary interventions to reduce metabolic dysfunction and the risk of cardiometabolic diseases in at-risk populations. She conducts human clinical trials to examine the effect of individual foods, bioactives and dietary patterns on risk factors for cardiometabolic diseases. In addition, she aims to translate research findings gained under highly controlled conditions to strategies, underpinned by behavior change theory, that improve the overall diet of free-living individuals.
