Accepts Healthy Volunteers
Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.
An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.
Searching Both is inclusive of interventional and observational studies.
|Eligible Ages||6 Years and Over|

Exclusion Criteria:- A diagnosis of celiac disease
This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.
Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.
Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.
Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
The sponsor is the organization or person who oversees the clinical study and is responsible for analyzing the study data.

BACKGROUND AND PURPOSE Many diseases, which are common in high-income countries, have an inflammatory component. In the world's rich countries, about 10% of the population will be diagnosed with a traditional inflammatory autoimmune disease during their lifetime. In an autoimmune disease, the body produces auto-antibodies against the body's own protein and the immune system destroys the body's own tissues. There are hundreds of different types of autoimmune diseases where some of the most common are; celiac disease (gluten intolerance), psoriasis, type 1 diabetes (T1D), multiple sclerosis, rheumatic diseases or thyroid diseases. Diseases such as cardiovascular disease, type 2 diabetes (T2D) and Alzheimer's disease are now also considered to have inflammatory components, and so-called auto-antibodies have been identified that indicate autoimmunity also in these diseases. Autoantibodies have also been identified in COVID-19 patients. To try to understand the biology behind autoimmunity and inflammatory disease, the investigators have analyzed the entire genome of patients with celiac disease as a model for autoimmunity. Celiac disease is a good so-called model disease for autoimmunity because the autoimmune reaction can be switched on and off with the help of gluten in the diet. With a strict gluten-free diet, virtually all signs of illness disappear and the inflammation ceases. The results from our whole genome analysis showed that genes involved in amino acid signaling were important for disease development and pointed to associations between celiac disease, T2D and anorexia. These results were somewhat surprising and the investigators began to look at the role of nutritional signaling and amino acids in inflammatory processes further. The purpose of this study is to test whether a reduction in certain amino acids (which is most common in wheat gluten) can improve glycemic control in healthy volunteers, parents, as well as children, adolescents and adults with diabetes and whether levels of inflammatory amino acids may be one of the factors behind the link between diabetes and severe COVID-19 infection. The participants will, for 4 weeks, eat one week as usual, eat one week wheat gluten-free, one week wheat gluten and one week with gluten and probiotics. The participants will be provided with continuous glucose monitors and activity-tracking bracelets. The investigators will analyze the efficiency of glucose uptake using continuous glucose monitors (CGM). During these four weeks, the research subjects will be admitted for 4 clinical visits (baseline, after 1 week, 2 weeks, 3 weeks) where blood samples will be taken. Also, during these weeks the participant will take capillary blood samples, faeces, urine, buccal swabs and saliva at home and fill out a questionnaire based on diet and risk factors for diabetes and questions about COVID-19. Total number of participants: 60 Sampling occasions per participant: 15 Follow-up period per participant: 4 weeks Number of years for inclusion: 2 years (20221201-20241201)
The study participants will start the gluten-free diet and be asked to exchange any products they normally buy with similar products. Three days in the week they will eat a meal with gluten free pasta. Two to six hours after the meal they will take samples at home and store until they return to the clinic.
Active Comparator: gluten
The study participants will continue the gluten-free diet and be asked to exchange any products they normally buy with similar products. Three days however, in the week they will eat a meal with regular gluten containing pasta. Two to six hours after the meal they will take samples at home and store until they return to the clinic.
Active Comparator: probiotic
The study participants will continue the gluten-free diet and be asked to exchange any products they normally buy with similar products. During the week they will also take probiotic (Probion, Active) every morning and every evening. Three days however, in the week they will eat a meal with regular gluten containing pasta. Two to six hours after the meal they will take samples at home and store until they return to the clinic.
