Paula Berstad conducts research on cancer prevention with a special focus on colorectal cancer screening. She is concerned with how diet and lifestyle should be taken into account in bowel screening so that this lifestyle-related disease can best be prevented through an optimal screening programme. She is involved in several research projects dealing with colorectal cancer screening, diet and lifestyle. Berstad is educated a nutritionist. She gave her PhD on fat metabolism and risk of cardiovascular disease at the University of Oslo in 2003. She has worked as a postdoctoral fellow and researcher in cancer and nutrition epidemiology at the University of Oslo, Akershus University Hospital and Telemark Hospital. She has also taught community nutrition at Akershus University College.
Paula Berstad conducts research on cancer prevention with a special focus on colorectal cancer screening. She is concerned with how diet and lifestyle should be taken into account in bowel screening so that this lifestyle-related disease can best be prevented through an optimal screening programme.
In the project CRCbiome , she and collaborators investigate relationships between diet, lifestyle, intestinal bacteria and precancerous lesions.
Berstad's research also includes projects where she and collaborators investigate in population studies whether lifestyle changes affect future cancer risk.
She is also involved in research on non-participation in colorectal cancer screening and measures to influence immigrants' participation in cancer screening.
