The long-term impact of diets rich in plant products on protein digestion and metabolism is still unknown, especially in older adults with higher protein needs. This study aims to compare the digestion and use of pea proteins in young and older adults, both vegetarians and omnivores. Volunteers are divided into four groups: young omnivores, young vegetarians, older omnivores, and older vegetarians. They take part in two clinical investigation days. On the first day, nitrogen retention and protein metabolism is measured after consumption of a pea-based meal. On the second day, amino acid digestibility of pea is evaluated. These results will provide valuable data on how plant proteins are digested and metabolized depending on age and diet. They will also help determine whether aging reduces the availability of plant proteins. This knowledge is important to support nutritional strategies for populations with specific protein needs, such as older adults.",[29,30,31],"Vegetarian Diet","Elderly","Young Healthy Adults",[33,34,30,35,36,37],"Amino acid bioavailability","Vegetarian diet","Plant protein","Protein utilization","Isotopic method","RECRUITING","2026-04-07",{"date":41,"type":42},"2026-04-09","ACTUAL",{"date":44,"type":42},"2025-10-22",{"date":46,"type":23},"2026-12-31",{"name":48,"class":49},"Institut National de Recherche pour l'Agriculture, l'Alimentation et l'Environnement","OTHER",1,{"id":52,"slug":53,"hasResults":11,"nctId":54,"briefTitle":55,"officialTitle":56,"acronym":4,"eligibilityCriteria":57,"healthyVolunteers":17,"sex":18,"minAge":19,"maxAge":58,"enrollmentInfo":59,"targetDuration":4,"studyType":61,"phases":4,"briefSummary":62,"conditions":63,"keywords":4,"overallStatus":38,"whyStopped":4,"lastUpdateSubmitDate":68,"lastUpdatePostDateStruct":69,"startDateStruct":71,"completionDateStruct":73,"leadSponsor":75,"locationsCount":50},"100617005","analysis-of-nfl-and-gfap-in-different-dietary-patterns-100617005","NCT07312994","Analysis of NfL and GFAP in Different Dietary Patterns","Vegan, Vegeratian, or Omnivore: Dietary Effects on the Brain Tissue Biomarkers","Inclusion Criteria:\n\n* Healthy individuals who have followed a vegan, vegetarian, or omnivorous diet for at least one consecutive year\n* Aged between 18 and 40 years\n* Provision of written informed consent\n\nExclusion Criteria:\n\n* Diagnose neurological disorders (e.g. neurodegenerative, inflammatory, autoimmune, infectious, vascular)\n* Eating disorders\n* Excessive alcohol consumption\n* Pregnancy\n* Recent moderate to severe infection (within the past 12 weeks) , including SARS-CoV-2\n* Recent trauma, injury, or surgery (within the past 12 weeks)\n* Significant BMI fluctuations (\\>5 points) within the last year\n* Patients who have been using Proton pump inhibitors (PPIs) for an extended period (e.g., 1 month).","40 Years",{"count":60,"type":23},300,"OBSERVATIONAL","This observational study aims to investigate the impact of different dietary patterns on brain tissue biomarkers in healthy young adults by measuring blood levels of NfL and GFAP.\n\nThe primary research question is: Do vegan, vegetarian, or omnivorous diets influence NfL and GFAP levels?",[64,65,66,67,29],"Neurofilament Light Chain","Glial Fibrillary Acidic Protein","GFAP","Vegan Diet","2025-12-17",{"date":70,"type":42},"2025-12-31",{"date":72,"type":42},"2025-12-18",{"date":74,"type":23},"2026-09",{"name":76,"class":49},"Salzburger Landeskliniken"]
