Brief Summary

Type 1 diabetes is an autoimmune condition where circulating immune cells destroy the beta-cells in the pancreas that make insulin, resulting in a degree of insulin deficiency, whereby blood glucose levels rise and diabetes develops. When there is severe insulin deficiency, life-threatening ketoacidosis can develop. Treatment is lifelong insulin replacement therapy; dietary intervention is a also cornerstone of glucose management. The Optimise Diet is a multi-pronged diet based on "best health" principles: to minimise blood glucose rises after eating, reduce the immune cells involved in destruction of the insulin-secreting beta-cells, and improve the gut microbiome and systemic inflammation. In this study, its effects will be compared to the Standard Diabetes Diet that is currently recommended in Australia and internationally.
