Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The primary objective of this study is to assess the construct validity and criterion validity for associations of the VEGANScreener with nutrient intakes from reference methods and associations with biomarkers of dietary intake. The investigators hypothesize that the screener is a valid tool to assess diet quality in the vegan population. The study will assess construct validity by testing whether the measure relates as it should to other measures (e.g., age, gender, education, SES differences).

The investigators will assess concurrent and predictive validity (types of criterion validity) by evaluating associations and agreement between 'gold standards', such as diet records, biomarkers, and multi-metabolite signatures of intake. The investigators will examine associations of vegan diet quality with biomarkers of nutritional status, biomarkers of disease, and anthropometric measures and hypothesize that a higher diet quality in vegans is associated with a more favourable profile among vegans, for example, a lower blood pressure. This study is part of the European VEGANScreener Consortium.
