J Health Popul Nutr. 2022 May 9;41(1):18. doi: 10.1186/s41043-022-00300-2.

Abstract

Objective: The relationship between vegetarianism and mental health is controversial. The aim of the present study is to examine the cross-sectional association between anxiety, depression, and vegetarianism in a French sample while controlling for potential confounders.

Design: Self-reported questionnaire data were obtained from a large cross-sectional sample.

Participants and setting: We included an online sample of 6578 participants aged 18-90, 70.8% females.

Results: Analyses of variance with age, gender, body mass index (BMI), educational level, monthly income, and city size as covariates showed that vegetarians and non-vegetarians did not appear to have significantly different levels of anxiety or depression.

Conclusion: Our findings do not suggest a link between plant-based diet and anxiety or depression, either before or after adjustment for relevant factors.
