What is this study trying to find out about diet and brain health?

This study aims to learn how vegan, vegetarian, or omnivorous diets affect brain tissue biomarkers called NfL and GFAP. Researchers want to understand if these diets influence brain health markers in healthy young adults. The study is sponsored by Salzburger Landeskliniken and focuses on comparing these dietary patterns.

Who may be eligible for this brain biomarker clinical trial?

Adults aged 18 to 40 who have followed a vegan, vegetarian, or omnivorous diet for at least one year may be eligible. Participants must be healthy, able to provide consent, and not pregnant. People with neurological disorders or recent infections may not qualify. Please review eligibility criteria for more details.

Is there any cost to participate in this brain biomarker clinical trial?

Study-related care, including all trial visits and tests, is provided at no cost. However, personal travel expenses may vary and are not guaranteed to be covered. Participants should plan accordingly for any costs related to travel or other personal needs.

What this Trial Is About

This observational study explores how different dietsvegan, vegetarian, or omnivorousaffect brain tissue biomarkers in healthy young adults. The research focuses on measuring the blood levels of neurofilament light chain NfL and glial fibrillary acidic protein GFAP to understand if these dietary patterns influence these brain-related markers. Participants are grouped based on their diet type omnivore, vegan, or vegetarian. The study does not involve any treatment or intervention but observes participants who have maintained their diet for at least one year. The main measurement is taken once at the start of the study to assess blood levels of NfL and GFAP. During the study, participants provide blood samples at baseline for biomarker analysis. Researchers monitor these levels to assess the impact of diet on brain health indicators. The study includes healthy volunteers aged 18 to 40 years and involves no treatment or follow-up visits beyond the initial assessment. Participation in the study lasts according to the single baseline measurement timeline.
