• Vegetarian documentary on Chinese social media sparked resistance despite a solid cultural foundation. • Ethical vegetarianism of the documentary conflicts with Chinese views of a balanced diet. • Vegetarian messages must align with local cultural norms. • Celebrity advocacy can appear elitist and ineffective. • Flexitarian approaches may better resonate for vegetarian promotion. The shift to a vegetarian diet has multiple benefits, including the promotion of public health, sustainability, and animal welfare. Despite these advantages, vegetarian food choices often provoke controversy, particularly on social media platforms. On International Vegetarian Day 2021, renowned Chinese actress Zhang Jingchu endorsed a documentary titled "Vegetarian" on Weibo, igniting widespread discussion among Chinese netizens. Considering China's deep cultural and practical roots in vegetarianism, the predominantly negative response to the documentary was surprising. This study employs frame analysis to dissect the portrayal of vegetarianism in the documentary, utilizing topic modeling based on Latent Dirichlet Allocation and sentiment analysis to examine over 26,000 related comments. Our findings indicate that the documentary predominantly utilizes health and ethical frames to represent vegetarianism, with a greater emphasis on ethical considerations. Topic modeling of the comments uncovered 14 topics that reflect netizens' dissatisfaction with various facets of the vegetarian advocacy presented in the documentary. Moreover, the comments reveal three primary strategies netizens use to justify meat consumption and alleviate cognitive dissonance: rationalization of meat eating, skepticism towards vegetarianism, and resistance to the advocacy message of "Vegetarian". The results imply that for vegetarian advocacy to be more effective, it should align with local everyday concerns, food culture, and the current stage of social development. [ABSTRACT FROM AUTHOR]

Background: A vegetarian diet may be a risk factor for depression, but this relationship was unclear in the elderly Chinese population.Methods: Self-report data were gathered from 1051 elderly persons using the Cohort of Elderly Health and Environment Controllable Factors, which was created in West Anhui, China. The depressive symptoms were set as binary, ordinal, and continuous outcomes, respectively, whereas the dietary structures were computed as an ordinal variable and a dummy variable. Multiple logistic regression, ordinal regression, and linear regression were used to assess the relationship by adjusting the potential confounding variables with p-values of <0.1 in univariate analysis.Results: The elderly participants who had a vegetable-based diet had the highest GDS scores of 8.78 ± 6.894 (p = 0.001) and the highest rate of depression (32.9%, p = 0.003). After adjustment for the potential confounders, elderly men who had a vegetable-based diet had a higher rate of depression (OR[95%CI]: 1.62[1.07-2.46], 4.71[1.38-16.03]), more severe symptoms of depression (OR[95%CI]: 8.85[2.94-34.12]), and higher GDS scores (β[95%CI]: 1.46[0.70-2.22], 2.97[1.28-4.67]) than male participants who had a meat-based diet, but this was not the case in women.Limitations: All data were self-reported. The study lacked quantitatively evaluated dietary intake. The duration of the current dietary structures and comorbidities were not reported. The cross-sectional study made the causal role uncertain.Conclusions: Vegetarian diets may pose a greater risk of depressive symptoms among the elderly Chinese population, especially elderly men. Given the cross-sectional nature of this study, the causal role was uncertain. Further prospective studies, in particular among elderly women, are needed. [ABSTRACT FROM AUTHOR]
