An integrated model of cannabis-infused food and beverage consumption in the USA based on the protection motivation theory and the value-attitude-behavior model

The adoption of unsustainable economic development processes has contributed to the emergence of a global crisis in which the planet's biophysical limits are being exceeded, with numerous implications for natural systems, biodiversity, and human health. This crisis further restricts access - especially among historically marginalized populations in Brazil and Latin America - to basic citizenship rights such as the right to land and food, creating what can be understood as a "crisis of crises." This opinion article begins by acknowledging the significant setbacks in various public policies in Brazil and Latin America, particularly those aimed at reducing inequalities and promoting citizenship. It presents evidence that overcoming the "crisis of crises," as discussed throughout the text, requires adopting models of food production, distribution, and consumption that are simultaneously sustainable, sovereign, and inclusive. It concludes by arguing that agroecology holds immense potential to foster, across different regions of Brazil and Latin America, an economy that is ecologically regenerative and socially distributive.

Introduction. Contemporary global environmental challenges, the intensification of climate change, and the transformation of food production and consumption models bring to the forefront the transition to a “green” economy and the formation of sustainable food systems. In this context, human capital in rural areas acquires particular importance, as its level of development determines the capacity of the agricultural sector to meet new environmental standards, implement innovative technologies, and adapt to institutional changes. Method (methodology). The study employs a set of general scientific and specialised research methods. Theoretical foundations are developed using methods of analysis and synthesis, induction and deduction, as well as systemic and structural-functional approaches. Comparative analysis is applied to generalise scholarly views. The assessment of the impact of human capital reproduction on the “green” transformation of food systems is conducted using economic and statistical methods, analysis of official data from the State Statistics Service of Ukraine, the OECD, and the FAO, as well as logical generalisation of research findings. Results. The reproduction of human capital in rural areas is considered a determining factor in the successful “green” transformation of food systems and the strengthening of their resilience. It is established that the qualitative characteristics of human potential directly determine the adaptive capacity of the agricultural sector to climate and resource constraints, as well as its ability to implement environmentally oriented technologies. It is substantiated that integrating human capital development policies into “green” transformation strategies is a necessary prerequisite for reducing socio-economic disparities and ensuring the sustainable development of rural areas. The findings confirm the expediency of a comprehensive combination of educational, socio-economic, and institutional instruments within the agricultural development management system.

ABSTRACT US consumers are increasingly focused on weight management. However, the economic impacts of this on the US food industry are not well understood. Thus, we estimate the effects of weight loss attempts on the consumption of and expenditures on a collection of 35 food groups. We obtain weight loss history and food consumption data from the National Health and Nutrition Examination Survey and Purchase to Plate Suite. Attempting weight loss is an endogenous choice and, as such, we use matching methods to reduce confounding. Matched samples and weights are used in lower‐limit censored outcome models of food consumption and expenditures. Nationwide weight loss attempts yield increases in daily expenditures on non‐citrus fruits, non‐starchy vegetables, and tomatoes of $17.8 million. Daily, national expenditures on processed grain products and soft drinks decrease by $18.8 million and $7.3 million, respectively. Food manufacturers and retailers can use these results to develop business strategy and mitigate risks associated with changing consumer behavior related to weight management. These findings can also guide public health and nutrition policies, directly speaking to how the composition of diets changes as consumers attempt weight loss.

ABSTRACTSustainable consumption behavior (SCB) has emerged as a critical area of inquiry within consumer research, particularly in response to escalating global sustainability challenges. While existing literature has increasingly addressed SCB, much of this work remains narrowly concentrated on the acquisition phase, with limited attention to the usage and disposal stages. Addressing this gap, the present study develops an integrated, stage‐wise model of sustainable food consumption encompassing acquisition, usage, and disposal behaviors. Grounded in the Norm Activation Model (NAM), the framework incorporates consumer attitude and consumer minimalism to provide a more comprehensive understanding of sustainable food behavior. Data were collected from a sample of 373 Indian consumers via a structured questionnaire and analyzed using SmartPLS v.4. The findings indicate that sustainable intention significantly predicts SCB across all three consumption stages, exerting the greatest influence during the acquisition phase, followed by disposal and usage. Moreover, responsibility attribution partially mediates the relationship between personal norms and consequences perception. Consumer attitude partially mediates the effect of personal norms on consumer minimalism, which in turn partially mediates the relationship between personal norms and sustainable intention. These insights offer valuable theoretical contributions and practical implications, particularly for policymakers and marketers in the food sector aiming to advance sustainable consumption in emerging markets. This study is among the few empirical investigations to systematically explore SCB across the full consumption cycle, thereby enriching the discourse on consumer behavior in alignment with Sustainable Development Goal 12.

We investigate a discrete-time model, PLSCQ, to describe interactions among fast food consumer categories, among five population categories: potential consumers (P), moderate consumers (L), excessive consumers (S), obese individuals (C), and individuals who have ceased fast food consumption (Q). We seek for an optimal strategy that minimizes the excessive consumer and obese populations while maximizing the number of individuals who stop or recover. We incorporate three control measures, representing media and education for potential consumers, healthy eating campaigns for excessive consumers, and treatment for obese patients. Employing the discrete-time Pontryagin maximum principle, we derive optimal controls and numerically solve the system in Matlab, verifying the strategy’s effectiveness through simulation results.

Community Supported Agriculture (CSA) is an important Alternative Food Network (AFN) in which consumers financially support small family farmers, sharing the risks and benefits of food production. This type of community is governed by rules based on collective and individual principles and values that produce, as an aggregate product, food security, environmental preservation, and income for small family farmers. CSAs are a food production and consumption model that directly connects farmers and consumers and promotes family farming, the local economy, sustainable agricultural production, and pro-environmental and prosocial behavior patterns. Considering the importance of CSAs for environmental sustainability and social justice and as a way of understanding the factors that promote these behaviors, a systematic review of the literature was carried out to identify studies that investigated actions by CSA members related to pro-environmental, prosocial, or health-related concerns, with (a) psychology as a theoretical-methodological approach or (b) identifying other areas of science interested in behavioral issues related to its members. While psychology studies on the behavior patterns of CSA members are rare, this aspect arouses interest in the multidisciplinary scientific community, as it stimulates and reinforces important and specific behaviors in the context of food and the preservation of the planet.

This study proposes a multibarrier model of sustainable food consumption by examining four major constraints: price, availability, trust, and time. Garrett Ranking analysis is used to determine the relative intensity of these barriers among consumers. The findings indicate that high prices are the most influential barrier, followed by the limited availability of sustainable food products. Distrust toward organic and eco-friendly labels emerges as a key perceptual obstacle, while time limitations associated with searching for and preparing sustainable foods further discourage adoption. The model illustrates how these barriers jointly influence consumption behaviour, showing that sustainable food choices are shaped by both economic conditions and consumer perceptions. The results provide practical insights for policymakers, retailers, and marketers to design strategies that enhance affordability, improve access, strengthen label credibility, and reduce time-related challenges, thereby encouraging wider adoption of sustainable food consumption.

During the outbreaks of forest insects, carbon is emitted into the atmosphere in the form of its dioxide. As a result of carbon dioxide emissions into the atmosphere, the volume of carbon deposited in stands decreases, and in order to assess the impact of insects on the process of carbon deposition by trees, a quantitative assessment of carbon dioxide fluxes into the atmosphere is necessary. The amount of damage to stands during an outbreak of forest phyllophagous insects, during which carbon dioxide is released into the atmosphere, was chosen as the object of research in order to get insights into the process of carbon dioxide emission. To analyse the processes occurring during the outbreak of pests, a model of food consumption by insects of different species was considered, based on the methods proposed for calculating carbon dioxide emissions into the atmosphere. Remote sensing methods of NDVI dynamics monitoring were used to assess the areas of stands damaged by insects. It was shown that a correct assessment of the area of the outbreak using remote methods should be carried out by comparing the NDVI distribution density curves in different years. Based on the data obtained, a method is proposed for assessing carbon dioxide emissions into the atmosphere during the mass reproduction of forest insects.

Abstract Many countries are currently facing the challenges of demographic aging and the transition to sustainable development. Under these conditions, promoting a sustainable model of food consumption among the elderly appears to be a desirable direction for policy intervention. The aim of the study is to measure sustainable food purchasing behaviour among consumers 55+ and to identify its determinants. Our study revealed, based on the results of a survey carried out among 401 Poles aged 55+, that the food purchasing behaviour of silver consumers is sustainable. It manifests in the strongest way in buying food in appropriate quantities and packing food in its own packaging. We used correlation and regression analyses to examine the presence of relationships between food purchasing behaviour and its predictors. Factors influencing the choices of consumers aged 55+ include personal and social norms, as well as perceived environmental awareness. Research results have enabled us to propose a conceptual framework for enhancing sustainable food consumption among silver customers.

PurposeThe purpose of this study is to assess the impact of consumption values on customer satisfaction and intention to consume millet-based foods. This study examines both tangible and intangible values of the millet-based food to the customer.Design/methodology/approachBased on consumption value theory (CVT), the present study evaluates the impact of consumption value factors such as emotional, epistemic, health, price, prestige and taste/quality values on satisfaction and intention to use millet-based foods and develops a unique research model. Later, leveraging a dataset comprising more than 410 responses from Pune city in India, a rigorous empirical examination of the proposed model was conducted employing SmartPLS 4.0 software.FindingsThe study's finding unveils both the significant and insignificant impacts of various consumption values, both from the tangible and intangible consumption value perspectives on satisfaction and intention to consume millet-based foods. The study also provides a validated food consumption model which can be used for other similar food consumption behaviour of the customers.Research limitations/implicationsThis study provides insights as to how different consumption values impact the satisfaction of the customers for the millet-based food. This study illuminates additional aspects of the tangible and intangible factors impacting the satisfaction level of customers to consume millet-based products. Also, this is a cross-sectional study, and the respondents are only based in Pune, India. Thus, the study results cannot be generalised.Originality/valueThis study employs CVT to explore the unexplored impact of consumption values on satisfaction and intention to use millet-based foods, which is unexplored in the past literature. Moreover, this study develops a theoretical model with high explanatory power, and the research model adds value to the existing body of literature from areas such as food preference, consumer behaviour and value consumption insights.

With the rising environmental awareness, the issue of food waste is drawing considerable attention from civil society, scholars, industry practitioners and policymakers alike. Addressing food waste is crucial, as it incurs a variety of social, health, economic and environmental costs, including greenhouse gas emissions, soil degradation and the depletion of natural resources. The objective of this study is to analyze processes in food waste management to gain insight into factors influencing consumer behaviour, attitudes, and practices regarding consumption and food waste and loss prevention in the supply chain. This requires the analysis of decision making methods and waste reduction strategies and approaches, particularly for households. The goal is to emphasize the importance of raising consumer awareness and sense of individual responsibility, especially given the recent surge in collective community intentions to live more sustainably. However, translating these intentions into tangible actions is uncertain and filled with socio-economic complexities. Reports indicate that, households are responsible for approximately half of all food waste generated. Therefore, it's important to review the literature on barriers and triggers related to behaviour patterns and variations in food related lifestyle dimensions, to determine the factors that might influence food handling and food waste knowledge. Targeting households presents a promising starting point for future interventions, highlighting actions that may influence the current food consumption model to reduce the amount of food wasted. The methodological approach was structured into three steps. First, a literature review was conducted to gather insights and identify factors and interconnections between consumer behaviour and food waste. Second, related drivers and triggers were analysed. Lastly, the findings were summarized to highlight gaps and opportunities for improving attitudes towards food waste prevention.

Dominant agri-food systems are increasingly seen as unsustainable in terms of environmental degradation, mass production or high food waste. In an attempt to counteract these developments and foster sustainability transitions in agri-food systems, a variety of actors are engaging in socially innovative models of food production and consumption. Using a multiple case study approach, our study examines three contrasting alternative economic models in the city of Berlin: community gardens, the app Too Good To Go (TGTG), and a cooperative supermarket. Based on 15 qualitative interviews, we provide insights into their transformative potential by exploring participants' underlying motivations, the changes they have experienced, and the challenges and potential for future development of these models. We find that participation in community gardens and the cooperative supermarket is similarly motivated by social aspects and dissatisfaction with existing food access options, while TGTG users are more motivated by financial reasons. Our study shows that change is experienced mainly at the individual level, e.g. by building new relationships, changing cognitive framings, and learning (new) practices, especially in community-oriented settings. The individualization of change shows that these models have a rather low potential to lead to more systemic accounts of changes. Yet, they can prefigure regime change, describe resistance, and foster cumulative incremental change that may spill over into society. We conclude that in order to sustain this role and drive transitions, it is important to up- and outscale these models; and we provide recommendations on how these models can mutually support their development, establishment, and protection.

Using Spain as a case study, we analyze the evolution of meat consumption from the 1950s to the present. A meat consumption database was constructed using four sources: the FAO, Ministry Balance Sheets, Household Budget Surveys and the Food Consumption Panel. The study has two main contributions. First, we question the idea that meat consumption in Spain has been increasing steadily since the 1950s, as some economic historians have reported. Second, we identify two different food consumption models. The first is characterized by an increase in standardized meat consumption and the second features decreased meat consumption alongside a rise in the consumption of processed and prepared meat.

According to the latest WHO guidance documents, activities on sustainable and healthy nutrition include a nutrient profiling stage as a basic condition for implementing evidence-based actions on issues such as the diet correction, the food recipes modification, the digital food environment and public procurement. The study aim is to systematize the available tools of nutrient profiling as effective practices for classifying and ranking food products in accordance with its ability to prevent diseases and promote human health. Nutrient profiling enables to rank products based on its nutrient content. There are many models of nutrient profiling in the world today, however most of them are not validated. One of the urgent tasks is to assess the prospects of using this tool in Russian nutritional practice. The authors analyzed materials and scientific sources that reveal the nutrient profiling essence, its history and timeline in different countries of the world. Nutrient profiling and nutrient profiling models in Russian practice can act as a policy tool in the field of the population nutrition improvement, for public health purposes, ensuring a balanced food consumption model, conscious and adequate food selection.

The research examined the possibility of food being socialized as local food to replace local food’s role in food tourism. Food was one of the major attractions during a vacancy in ASEAN. The study of food in tourism rarely considered local food diversity in urban areas. The research addressed the other type of local food that is typical city food. In this case, there is no connection between the food and culture, traditions, history, or place, but the food is socialized as being indigenous. The local food consumption model was used to test whether the factors that affect tourists' local food consumption apply equally to foods socialized as local food. The research compared domestic tourist local food consumption factors in two food categories. 640 domestic tourists in a developed culinary tourism city in the Jakarta Metropolitan Area participated in this online survey. The comparative test of tourist characteristics found gender, the purpose of visit, age, and status of visit tourist characteristics associated with the food choice. The physical environment, exiting experience, and authentic experience were the motivational factors that differed between two food categories. It is possible that socialized foods will replace local food. The food locality did not always a matter. The results provide an overview of the position of local food in urban tourism. This has been considered the main attraction of food tourism in ASEAN countries.

Purpose: This research work attempts to review the effect of determinants like perceived uniqueness and perceived healthiness as well as attitude amongst the consumers towards their purchase intention of organic food, which subsequently results in the actual purchase. Design/Method/Approach: Quantitative approaches and explanatory research are used in this study. This research data was collected by means of a questionnaire distributed across a sample of consumers living in Indonesia. An online survey was used and conducted in November 2022 in Indonesia to measure this research. The sample, which was collected through the online survey using Google Form, consisted of 780 participants and was representative of gender, age, and region. Actually 800 participants were contacted to participate in the survey, but only 780 participants responded to the online survey. Findings: The first objective of this study was to test the ability of the extended Value Attitude Behaviour (VAB) model to explain the consumption of organic food products by Indonesian consumers. The results show a good fit of the data. The third hypothesis was confirmed because attitudes are closely related to organic food consumption. Organic food products were considered and perceived as something unique and natural; therefore, they provided a favorable attitude among the part of the respondents. Theoretical Implications: The study contributes to existing literature on organic food products especially about variables used in this study. In addition, in this study, consumers' perception of organic food products as unique, natural, healthy and sustainable was positively related to their overall attitudes. Practical Implications: Given the high production costs and limited quantities of organic food products, marketers should present and promote (through packaging and stores) organic food products as the ones of unique quality and should emphasize their natural character. Originality/Value: This paper provides a comprehensive overview and links the literature on organic food consumption to Value Theory and the Theory of Planned Behaviour, including the role of perceived uniqueness and healthiness. The proposed integration of perceived uniqueness and healthiness in an organic food consumption model leads to interesting hypotheses and recommendations for policy makers, researchers and stakeholders involved in the organic food market. Research Limitations/Future Research: This study provides a good indication regarding consumers’ attitudes, perceived naturalness, and perceived uniqueness of organic food products. However, as only 55% of the respondents had consumed organic food products, the attitude and beliefs of 45% of the respondents were not based on actual experience, but on expectations and beliefs. We believe consumers’ attitudes and beliefs may differ after trying organic food. Therefore, it would be interesting to study eventual variations in attitudes and beliefs before and after trying organic food products. Paper Type: Empirical JEL Classification: D11, M31, Q13

The purpose of this scientific article is to research the important issues of food supply in Ukraine at the regional level by diagnosing the current state of food ensuring based on a survey of relevant respondents with the purpose to improve the level of socio-economic development of the country in the long run.In research have been interviewed households from Kyiv of Ukraine according to the following main criteria: physical and economic conditions, food availability, supply and access to food consumption to evaluate household food security status by calculating the sample size, a few details about the target population, its size, variance, margin of error and desired level of confidence in empirical estimates of important variables.In this research, the Minimum Dietary Energy Requirement (MDER) and a threshold that shows the minimum amount of energy needed by a hypothetical average person in the population to be healthy and engage in socially acceptable levels of activity have been examined. The state of nutritional food security in terms of protein, carbohydrate, and fat consumption has been investigated.The main aspect of the results approved that almost half of the respondents are showing conditions of life for them as “just adequate and few people seem not to be satisfied showing «less than adequate». These results are important from the viewpoint of food security as adequate food intake; availability and sustainability are the main components of food security and show the quality-of-life status.It is proved that at the present stage of national economic status human development plays an important role in achieving long-term food security goals. It has been established that in order to attain sustainable food safety at the national level, it is important to improve the population's health condition and to change the existing food consumption models in the country, in households in particular the food basket containing imported foodstuff. This can be achieved through promoting safe and healthy eating habits, education improving in the field of food systems and technologies, and facilitating access to information for consumers and producers.

Contributions to a more sustainable model of food production and consumption in Portugal: an opportunity to reduce the ecological footprint of food

This article evaluates the possibility of resolving three imbalances in Portugal in a single equation: reducing the food footprint, improving the trade balance, and increasing human consumption of vegetables, contributing to a healthier diet.According to our results, a reduction in the consumption of beef, achieved mainly by reducing imports, combined with an increase in the production of vegetables and cereals for baking, reduces the trade deficit by around 460 million euros per year and improves the Food Footprint by 20% in average.These goals, along with the increased consumption of vegetables, also have a positive effect on the health of Portuguese families.To achieve these objectives, it is necessary to establish new rules for the application of the common agricultural policy in Portugal.
