Multiple Ascending Dose of DW4421, phase I

This prospective cohort study aims to constitute a 500-participant database and biobank including 450 adults with systemic autoimmune diseases (rheumatoid arthritis, systemic lupus erythematosus, systemic sclerosis) and 50 healthy controls.

The aim of this randomised controlled trial is to investigate the effects of plant foods on gastrointestinal and cardiometabolic health in healthy adults aged 30-70 years old. The main question it will answer is "what is the effect of plant foods on alpha-diversity of the gut microbiota?". Researchers will compare two diets containing plant foods to see if they have different effects on gastrointestinal and cardiometabolic health. Participants will be asked to replace all their meals, snacks and drinks with those provided by the study team for four weeks (6 days/week). Participants will also be asked to attend the research facility on three occasions to: * Provide a blood sample * Provide a urine sample * Provide a stool sample * Have their body composition assessed * Have an ultrasound of their artery (arm) * Have their blood pressure measured * Answer questionnaires related to dietary intake, mental health, physical activity, quality of life, diet acceptability and adherence
