Overview

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.

The primary research question is: Do vegan, vegetarian, or omnivorous diets influence NfL and GFAP levels?

Eligibility

Inclusion Criteria:

  • Healthy individuals who have followed a vegan, vegetarian, or omnivorous diet for at least one consecutive year
  • Aged between 18 and 40 years
  • Provision of written informed consent

Exclusion Criteria:

  • Diagnose neurological disorders (e.g. neurodegenerative, inflammatory, autoimmune, infectious, vascular)
