A number of external international experts in nutrition, epidemiology, preventive medicine
and public health, including experts with experience in dietary assessment tools´
development and plant-based diets were invited to join our team experts in reviewing the
evidence, the proposed items´ pool and finalizing the VEGANScreener through provision of
expert opinion and voting. In November and December 2022, an expert panel participated in
two anonymous survey rounds (25 in the first and 19 in the second round), and an online
wrap-up meeting to finalize this rapid diet quality assessment tool for vegans in Europe.
We express our gratitude to experts for dedicating their time and expertise to this project!
