摘要

Recent studies from China and India, none designed to assess vegan status, reported unusually large vegan samples (n = ~1000–8000) and prevalences (~1–9%). These were mostly inferred from short food frequency modules or short-term dietary assessment (e.g., 1 month). Many inferred vegans were socioeconomically marginalized or socially excluded. This perspective argues that the reported prevalences largely result from underassessment of intake and misclassification rather than adherence to vegan diets.
