Project Title: Applicability of ulcerative colitis dietary guidelines in New Zealand

Several international dietary guidelines, reviews and studies for ulcerative colitis have been published over the years. However, these guidelines are not easily applied in a NZ setting due to limitations of resources in our health sector. Additionally, the dietary advise may not be relevant to new zealanders due to differences in cultural and social practices and availability of recommended food choices. In this project, we will develop dietary recommendations for UC that is better aligned with the NZ healthcare resources particularly in the smaller or under resourced regions of Aotearoa. Additionally, we will collect feedback from ulcerative colitis individuals to better understand their dietary habits in relation to their disease to ensure better uptake of dietary recommendations.

Project Title: Assessing the utility of measuring mesentric adipose tissue in Crohn's disease

Belly fat is reported to have an important role in Crohn's disease progression. This makes belly fat a potential therapeutic target that can be influenced by the external environment including the gut microbiota and diet. In this study, we validate the use of imaging as a non invasive diagnostic tool for measuring inflamed belly fat in people with Crohn's disease. The imaging tool can be used to assess the effectiveness of different therapies on belly fat to improve outcomes for sufferers of Crohn's disease
