Lay summary
Diabetes is a complex chronic condition and a significant health concern in Aotearoa. Effective management is demanding, individuals make up to 180 diabetes-related decisions daily. Automated insulin delivery systems pose a treatment that reduces this burden while improving outcomes. However, in Aotearoa, nutrition therapy, a key component of diabetes care, has not been fully explored in combination with modern treatments such as automated insulin delivery and glucagon-like peptide-1 receptor agonists. By synthesizing findings from multiple projects, this research aims to deepen understanding of how diet affects glycaemic control when used with modern diabetes treatments. This research will focus on diverse groups within the New Zealand population, including minority ethnic groups such as Māori and Pacific peoples, as well as older adults. The aim is to inform research and advance nutrition therapy in optimising diabetes management tailored to a local context, improving diabetes control and outcomes.
