The document describes the CD-DIET research study which aims to screen people with type 1 diabetes for celiac disease. Celiac disease is an autoimmune condition triggered by gluten that can cause intestinal damage and nutrient deficiencies. The study offers blood tests to diagnose celiac disease in people with diabetes aged 8-45 who have not been recently tested. For those diagnosed, the study will assess the impact of a gluten-free diet over one year. The goals are to improve understanding of managing both conditions and ensure accurate diagnosis of celiac disease in the diabetes population.
