Gradual behaviour change towards meat reduction: Development and validation of a novel decisional balance scale

Shades and shifts in flexitarian and meat-oriented consumer profiles in a German panel study

Consumers' growing awareness of the adverse effects of high meat consumption has led to increased attention to flexitarian or meat-reduced diets. However, most flexitarians do not significantly reduce their meat consumption and still eat many meat-based meals. This study aims to classify the large and heterogeneous consumer group of flexitarians into different profiles based on attitudinal, normative, and control beliefs about meat reduction. Being aware that consumer profiles can change over time, this study explores the dynamics of the identified profiles using a two-wave panel survey of 430 German consumers. Latent profile analysis revealed distinct flexitarian and meat-oriented consumer profiles, including three stable profiles and one non-stable profile across both waves. The findings indicate that flexitarian and meat-oriented consumer profiles differ significantly in their belief structure about meat reduction and that consumers can switch back and forth to other profiles over time. Practitioners should be aware of changes in the belief structure of flexitarian and meat-oriented consumer profiles when developing meat reduction interventions. Further research is needed to understand the reasons behind these profile shifts.

Effectively implementing healthy and sustainable food practices in out-of-home food service locations: The perspective of the catering staff members

Restaurants, canteens, residential care, hospitals and other out-of-home food service locations can play an important role in improving people's diet quality by offering healthier and more sustainable food choices. However, the effectiveness of implementing sustainable and healthy food practices at these locations is, at least partly, dependent on the extent to which they are accepted and implemented by the staff members. This study aims to assess staff members' motivation, perceived capability, perceived opportunity and their readiness to change their behaviour (i.e., stages of change) in offering more healthy and sustainable food options to their customers or patients. Eleven out-of-home locations that wanted to adjust their assortment towards more healthy and sustainable product offerings participated in this study and were able to distribute a comparable questionnaire among their staff members to assess their perceived readiness to change. Results among 268 participants show that staff members find both a healthy and sustainable food assortment important and also seem to be motivated to improve their food assortment regarding health and sustainability. Perceived opportunity seems to be the largest barrier for staff members, although there is also room for improvement regarding their perceived capability. In addition, personal motivation seems to play the dominant role in staff members' readiness to change the health of the assortment, whereas perceived capability seems to play the dominant role in their perceived readiness to change the sustainability of the assortment. This study shows that taking into account the perspective of the catering staff members may help to effectively implement healthy and sustainable food practices in out-of-home food service locations.

A horizon scan of global biological conservation issues for 2024

We present the results of our 15th horizon scan of novel issues that could influence biological conservation in the future. From an initial list of 96 issues, our international panel of scientists and practitioners identified 15 that we consider important for societies worldwide to track and potentially respond to. Issues are novel within conservation or represent a substantial positive or negative step-change with global or regional extents. For example, new sources of hydrogen fuel and changes in deep-sea currents may have profound impacts on marine and terrestrial ecosystems. Technological advances that may be positive include benchtop DNA printers and the industrialisation of approaches that can create high-protein food from air, potentially reducing the pressure on land for food production.

Stages of Change toward Meat Reduction: Associations with Motives and Longitudinal Dietary Data on Animal-Based and Plant-Based Food Intakes in French Adults

BACKGROUND

Reducing meat consumption is advocated for healthier and more sustainable diets. However, behavioral studies are needed to better understand the mechanisms underlying meat-reducing dietary changes.

OBJECTIVES

The main aim of this study was to compare the motives associated with stages of change toward meat reduction in French adults, using the transtheoretical model (TTM). A second aim was to investigate the associations between stages of change and adherence to dietary patterns favoring a better balance of animal and plant food consumption over time.

METHODS

This longitudinal study included 25,143 non-vegetarian participants of the web-based NutriNet-Santé cohort with a mean follow-up of 6.2 (SD = 2.6) y. Dietary data were obtained from 24-h dietary records over the period 2009-2019. The contribution of meat to total energy intake and scores measuring the contribution of healthy and unhealthy plant-based foods to the diet were computed. A questionnaire completed in 2018 allowed us to identify the TTM stages of change related to meat reduction (precontemplation, contemplation, preparation, action, and maintenance), and recorded motives related to meat consumption. We used multivariate linear mixed models for repeated data to assess associations between food intake changes and stages, and logistic regression for motives, presented as adjusted frequencies.

RESULTS

Participants in later stages were characterized by a significantly higher decrease in meat intake over time, compared with the earliest stage (for example, βmaintenance ∗ time = -0.08, P < 0.0001), and a higher increase in the healthy plant-based food consumption score over time (for example, βmaintenance∗time = 0.11, P < 0.0001). Concerns about health, nutrition, and the environment were the most frequently cited motives for reducing meat consumption at all stages.

CONCLUSIONS

Individuals who had already initiated meat reduction adhered to healthier and more sustainable diets than meat continuers. Characterizing motives according to readiness to reduce meat consumption could support tailored public health campaigns.
