Numerous studies have shown that replacing a portion of beef with plant-based foods in daily diets of high-income nations can improve health, nutrition, and environmental consequences globally Pulses are one of the major plant-based protein foods shown to have both environmental and nutritional benefits For consumers to adopt more plant-based foods in their diets, more options are needed that meet consumer demands for taste, convenience, nutrition, and sustainability along with dietary preferences Beef-based burger patties can be made more sustainably, nutritiously, and cost-effectively while maintaining palatability by reformulating with a portion of pulses such as whole cooked lentils The aim of this study was to quantify the nutritional and environmental benefits of such lentil-reformulated beef burgers Here we compared the nutrient balance score (considering 27 essential macro and micronutrients) and environmental footprints (carbon, bluewater, water scarcity, land use, and biodiversity) of an all-beef burger with a beef burger reformulated with a portion of cooked lentil puree The geographic resolution of the analysis was Saskatchewan, Canada Results showed that partial replacement of a lean beef burger with cooked lentil puree increased the nutrient density by ~20%, decreased the life cycle environmental footprint by ~33%, and reduced the cost by 26% In particular, the lentil reformulated burger had 60 times higher dietary fiber, three times higher total folate, five times higher manganese, and 16 times higher selenium than the all-beef burger We highlight the importance of using high-spatial resolution inventory of agricultural inputs and characterization factors (impacts per unit agricultural inputs) to obtain more accurate environmental results The results underscore the potential of food innovation to contribute towards multiple global sustainable development goals

Nutritional and Environmental Sustainability of Lentil Reformulated Beef Burger

Sustainable diets are patterns that change consumer behaviour towards more balanced and plant-based habits. This study investigates the effect of individuals’ predisposition to adopt sustainable diets while reducing meat intake by measuring their psychological proximity to meat. Using an online consumer-based platform, a cross-sectional survey collected responses from 497 individuals. Questionnaire items included 43 questions prospected from the literature, coded as practical and essential barriers and measured on a modified 7-point Likert scale. The results showed some paradoxes, as a high predisposition to adopt a sustainable diet coexists with a high predisposition to consume animal-based proteins. The main perceived barrier to adopting a plant-based diet was the enjoyment of eating meat, followed by the lack of information about plant-based diets. Barriers related to meat alternatives remained the highest above all the others. It confirms that, for local consumers, meat remains a usual option and is easier to prepare. When investigating the moderating effect of barriers on the predisposition to behaviours towards meat intake reduction, no effect was confirmed. However, we found a U-shaped moderating effect for plant-based meal increase, confirming the psychological proximity of the meat consumption effects under the lens of the Construal Level Theory and Transtheoretical Model. These findings call for further research on the effectiveness of measuring psychological barriers related to sustainable diet adoption.

Psychological Barriers to Sustainable Dietary Patterns: Findings from Meat Intake Behaviour

Front of Package (FOP) labeling, which assists consumers in understanding the nutritional status of fresh pork, could help reduce Chinese residents’ excessive meat intake and greenhouse gas emissions. Nevertheless, little is known about the price elasticity of consumers’ demand for the FOP labeling on fresh pork. This study implemented a contingent valuation survey by using a representative survey of 930 adults across China. The results indicated that respondents’ demand for FOP labeling applied to fresh pork was price inelastic (−0.209). Moreover, there existed significant population heterogeneity in the price elasticity of demand. Specifically, WTP increased for the urban population and those who paid regular attention to pork’s nutritional value. Overall, Chinese consumers had rigid demand for FOP labeling on fresh pork, and policy makers should pay close attention to consumer reactions to the price of FOP labeling and promote this application on fresh pork.

Sustainable Healthy Diets and Demand for the Front-of-Package Labeling: Evidence from Consumption of Fresh Pork

This cross-cultural study aimed to determine the main factors behind potential changes in eating habits by analyzing changes in the patterns of beef consumption currently observed in Brazil, Spain, and Turkey. To achieve this aim, 412 regular beef consumers from Brazil, 407 from Spain, and 424 from Turkey answered a self-administered questionnaire. The study surveyed the effects of economic factors, switching from beef to other sources of protein, aspects of credence, health-related concerns, the influence of lifestyle on beef consumption patterns, and purchasing decision factors. The most important factors that changed consumer behavior and resulted in a decrease in consumption, mostly among Brazilian and Turkish consumers, were the economics and accessibility of the products. Beef was replaced by other alternative sources of protein that were likewise derived from animals. The consumers whose purchasing intentions were most significantly influenced by credence factors (e.g., indiscriminate use of agricultural products, substandard animal welfare requirements, among others) were Brazilian and Turkish and, to a lesser degree, Spanish consumers. Lifestyle factors (e.g., consumption of out-of-home meals, available time to cook, among others) were demonstrated to alter consumption patterns and therefore must be carefully considered by the industry, taking into account cultural differences and consumer needs. The population under investigation considered that eating beef had no impact on their health.

Changes in the Current Patterns of Beef Consumption and Consumer Behavior Trends—Cross-Cultural Study Brazil-Spain-Turkey

ABSTRACT The study of sustainable food consumption is key in the transformation of current unsustainable food systems. We explore the tensions that emerge between individual motives and sustainability spheres when making food consumption choices in a university community in Bogotá, Colombia. This complex phenomenon is addressed through a qualitative methodology based on observations, visual diaries, and a game-based protocol, which allow us to delve into food consumption motives while trying to avoid social desirability bias. Our results show a plate that is high in cereals, roots, tubers, plantains, and animal-based protein, and low in vegetables, fruits, and plant-based proteins. Behind this plate, most tensions emerge between family traditions and other sustainability spheres. These tensions are related to socio-affective risks, animal suffering, time constraints, effort, and monetary costs. Integrating sociocultural elements such as family traditions in public policy becomes fundamental when promoting sustainable diets in similar contexts. This study contributes to the discussion about the sociocultural changes required in the transition toward sustainable food systems.

Towards Sustainable Food Consumption: Emerging Tensions Behind the Plate in a Colombian University Community

The growing demand for meat and animal products in emerging economies has become a concern given its environmental and health impacts. The sustainable diets approach has emerged to address the multidimensional challenge of reaching a context-based diet that minimizes negative environmental impacts, provides health and nutrition to all segments of the population, and is affordable and coherent with the local culture and traditions. The aim of this study was to explore the prospects for meat consumption reduction and challenges encompassing the environmental, and health spheres. In order to do so, we analyzed: (1) The current carbon and water per capita footprints for two animal-based options and two plant-based options; and (2) the contribution of each food alternative to the local dietary reference intakes based on average per capita daily consumption and significant differences among the nutrient values for each food alternative through a two proportion Z-test. Our results show that the annual per capita carbon and water footprints for beef were higher compared to other alternatives, despite a higher per capita consumption of chicken. Also, our findings reveal that the average consumption of beef and chicken contributes 39% of the maximum recommended daily intake for cholesterol and 61% of the Recommended Dietary Allowance for protein in the country. Finally, relevant promoting forces and barriers related to meat consumption reduction were identified based on the two dimensions evaluated. This study calls for a joint effort to make changes in public policy, food systems, and consumer education.
