Sustainable Diets and Meat Consumption Reduction in Emerging Economies: Evidence from Colombia

Does Consumers' Cultural Background Affect How They Perceive and Engage in Food Sustainability? A Cross-Cultural Study

Motivated by the evolving global food landscape and its detrimental impacts on society, the environment, and health, this research aims to understand consumer perceptions, preferences and involvement regarding sustainable food products and consumption practices. To this aim, three countries were chosen for their distinct economic, cultural, and demographic differences (Spain, Türkiye, and Colombia), enabling an exploration of how these factors influence sustainability perceptions. The results show high levels of awareness, knowledge, consumption, and willingness to switch to more sustainable habits, although differences between countries were also found (price sensitivity in Spain and demand for information regarding sustainable food in Colombia). In addition, a group of consumers has been identified that is influenced by health, shows positive behaviours and perceptions towards sustainable food, and is not price sensitive. The study is significant, as it addresses the information gap between consumers, producers, and policymakers regarding sustainable food awareness. It seeks to provide insights into cultural influences on sustainability perceptions and aims to assist in developing educational programs and policies to promote sustainable consumption.

Can in vitro meat be a viable alternative for Turkish consumers?

High meat consumption places a heavy burden on the environment. This study aimed to highlight the practices of Turkish consumers in consuming red meat and to understand their attitudes toward in vitro meat (IVM). The relationships between red meat consumption rationalization, attitudes toward IVM, and intentions to consume IVM were examined for Turkish consumers. It was found that Turkish consumers' attitudes toward IVM were averse. Even if the respondents considered IVM a viable alternative to conventional meat, they did not consider it ethical, natural, healthy, tasty, or safe. Additionally, Turkish consumers did not evince interest in regular consumption or intention to try IVM. Although various studies have focused on consumers' attitudes toward IVM in developed economies, the current study is the first attempt to understand the phenomenon in the Turkish market as an emerging economy. These results provide important information for researchers and stakeholders in the meat sector, such as manufacturers and processors.

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

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.

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

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.

Nutritional and Environmental Sustainability of Lentil Reformulated Beef Burger

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 1.6 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.
