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.

- - Participants with a confirmed diagnosis of CD were actively included for different treatment strategies.
- - Participants with multi-system organ failure and/or other severe diseases not suitable for CD treatment intervention were further excluded.
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.

Crohn's disease (CD) is a chronic recurrent systemic inflammatory disease, mainly affecting the gastrointestinal tract, accompanied by extra-intestinal complications and immune dysfunction. The relationship between other dietary components and disease activity or recurrence has not been fully studied and there is still no recognized daily diet model for CD. At present, the change of intestinal microbiome is considered to be one of the causes of Irritable Bowel Disease (IBD), and this change provides a theoretical basis for diet to reduce the inflammatory response those with CD through the regulation of microbiome. In inflammatory diseases, the potential inflammation of food may affect the activity of the disease. Empirical Dietary Inflammatory Pattern (EDIP) is a dietary inflammation index based on food group. 18 food groups were selected to evaluate the levels of inflammatory factors in human body which have already been verified by two independent female and male cohorts. The construction and validation of the scoring model revealed a strong correlation between EDIP and three plasma inflammatory markers: IL-6, CRP and TNFaR2, as well as other markers, such as adiponectin and the overall inflammatory marker score. Therefore, EDIP can be derived in a standardized way in different populations and be used to examine association with diseases whose pathogenesis is mainly attributed to chronic inflammation. Dietary inflammation index (DII) is a previously developed inflammation index based on nutrients. Compared to DII, dietary patterns based on food groups, such as EDIP, are more valuable for the establishment of dietary guidelines for health promotion and disease prevention. In addition, the brain-gut axis is the kink between the central nervous system and intestinal function but has not been extensively studied. In view of the fact that autoimmune diseases, and brain-gut axis interaction may play an important role in CD, we speculate that cerebrovascular function may also change during the occurrence and development of CD, especially during the EDIP score-based diet. The investigators plan to carry out a randomized controlled trial to systematically study the effects of EDIP score-based dietary suggestions on disease activity and cerebrovascular function of CD patients, as well as the changes of intestinal flora and its metabolites. The primary aim of this study is to systematically study the effects of EDIP based dietary recommendations on disease activity and cerebrovascular function of CD patients and establish a diet model suitable for CD patients. The secondary aims are to explore the possible changes of intestinal flora and its metabolites, and evaluate the changes of cerebrovascular function and the possible mechanism of their actions on CD.
