Purpose: Meat consumption causes a large amount of global greenhouse gas emissions and other environmental problems. Studies showed that consumers underestimate the environmental impact of meat consumption compared to other food-related behaviours. A video intervention was conducted to investigate the effect of information on consumers' perception and behaviour.Design/methodology/approach: Two didactically different videos about meat and the environment and a control video were shown to 189 participants. Ratings about the environmental impact of different food-related behaviours as well as participants' meat consumption frequency were obtained directly before, one week later and one year after the screening by self-report questionnaires.Findings: Mean rating of the environmental impact of meat consumption was second to the least important of the different food consumption patterns. In the first intervention group, the rating increased significantly (p = 0.001) after having watched the video. There was no such effect in the second intervention or the control group. Self-reported meat consumption frequency did not change significantly in any of the groups. No long-term differences between the groups could be found.Research limitations/implications: The results suggest that there is still a lack of knowledge concerning the environmental impact of meat consumption. Providing information can affect awareness, depending on the type of information delivery. The circumstances under which information encourages behaviour change need to be further explored.Originality/value: This is the first study that investigated the impact of different videos about environmental impacts of meat consumption on consumer perceptions and behaviour.

Background: Previous studies have examined the quality of life of patients with coeliac disease. There is a lack of understanding about potential changes in emotional responses and life challenges after diagnosis. This exploratory study aimed to evaluate the emotional impact, life challenges and quality of life in people living with coeliac disease in Germany.Methods: An online survey was conducted among patients with coeliac disease to assess difficulties in implementing a gluten‐free diet in daily life activities, including food shopping and preparation, and eating away from home, as well as additional costs of time and money. Furthermore, the questionnaire assessed the time of diagnosis, emotions felt after diagnosis and today, compliance regarding the gluten‐free diet and sociodemographic data. Participants were recruited in 2022 via social media, newsletters and websites. Out of 1286 participants who had taken part in the survey, 766 met the inclusion criteria and were included in the data analysis.Results: The majority of the respondents (aged 18–83 years) were female (93%) and almost 50% were diagnosed more than 5 years ago. Negative emotion ratings related to the disease were associated with age at the time of diagnosis and years passed since diagnosis. While compliance was high with 89% of respondents strictly adhering to the gluten‐free diet, patients with coeliac disease reported mainly life challenges in social situations involving food such as out‐of‐home consumption in restaurants, at work and while travelling. These challenges appear to persist over time.Conclusions: Negative emotions and difficulties in implementing a gluten‐free diet are negatively impacting individuals with coeliac disease, particularly in the first months after diagnosis. Particularly adolescents and young adults appear to be negatively impacted. The study emphasises the need to improve the quality of life in all impacted areas through better guidance and improved training of health professionals as well as food providers outside of home and through psychological counselling in the first year of diagnosis to better help individuals improve their quality of life.
