Abstract
The literature indicated that deceivers in face-to-face communication experience psychological strains derived from guilt or distress associated with violating conversational rules. We proposed that this also applies to telephone-mediated deception. Drawing insights from the theoretical and empirical literature, we surmised that strategic trickery utilized by outsourced call center agents would elicit adverse psychological reactions that have unfavorable impacts on their well-being, cognition, and work motivation. We used structural equation modeling to test our hypotheses using data from a sample of 554 outsourced Filipino call service agents who worked graveyard shifts to cater to mainly American customers. The results suggested that strategic deception increases the experience of cognitive dissonance while negatively impacting psychological well-being and intrinsic work motivation. The results also showed that dissonance negatively influences well-being and intrinsic motivation and partially mediates the deception-motivation relationship. Unlike previous findings, however, our multivariate analyses revealed that well-being and motivation were not correlated. Our original findings have theoretical and practical implications.

Büyük Z, Dulger Altiner D. Investigation of antioxidant and sensory properties and in vitro bioaccessibility of low-fat functional cookies substituted with wheat germ flour and coffee silverskin. JOURNAL OF THE SCIENCE OF FOOD AND AGRICULTURE 2024; 104:1322-1334. [PMID: 37770412 DOI: 10.1002/jsfa.13013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/17/2023] [Revised: 09/14/2023] [Accepted: 09/29/2023] [Indexed: 09/30/2023]
Abstract
BACKGROUND This study aimed to produce new functional cookies with high nutritional properties and low calorie content. It investigated the effects of incorporating wheat germ flour (WGF) at levels of 10-30% as a substitute for whole wheat flour (WWF), along with coffee silver skin (CSS) in the same proportions, serving as natural functional additives to substitute for fat in cookie formulations. RESULTS The total phenol content of the cookies with added WGF-CSS ranged from 1813.72 to 1838.45 mg gallic acid equivalent (GAE) per kilogram of dry weight (mg GAE kg-1 ), whereas the total phenolic bioaccessibility values ranged between 53.39 and 56.84%. Of the three methods used to determine antioxidant capacity (AC), the cupric reducing antioxidant capacity (CUPRAC) method gave higher bioaccessibility values (44.55-51.19%) than the 2,2'-azino-bis (3-ethylbenzthiazoline-6-sulfonic acid) (ABTS) radical cation and 2,2-diphenyl-1-picrylhidrazyl (DPPH) scavenging methods. The contribution of WGF-CSS supplemented cookies to the recommended dietary allowances (RDA) (%) of K, P, Mg, and Ca increased depending on the number of cookies consumed and the WGF and CSS ratio. The general acceptability scores of the cookies varied between 5.66 and -7.08, and the 10% WGF cookie (F2) (6.48) sample received the score that was closest to that of the control. Moderately strong positive relationships (r > 0.90, P < 0.05) were detected between the physicochemical and sensory characteristics of the cookies. CONCLUSION As a result, WGF and CSS food additives with high nutritional properties can be recommended as potential enriching ingredients and fat substitutes in the development of new products in the functional food industry. © 2023 The Authors.

Abstract
Duck meat is known for its taste and high nutritive value. To preserve local genetic diversity while maintaining commercial viability, we obtained a crossbreed (CB) between high-performing Cherry Valley (CV) and traditional Chinese crested (CC) ducks. We compared carcass traits and meat quality characteristics of CB and parental breeds. Meat from the above ducks at their respective marketable ages was evaluated for proximate composition, amino acid and fatty acid profiles, and selected mineral content. The live weights, carcass weights, and breast muscle percentage of CB were higher than CC but lower than CV; the leg muscle of CB was lower than CV and CC. CB had higher intramuscular fat content than CV; its collagen content was lower than CC but higher than CV in breast and thigh muscles. Additionally, the saturated fatty acid content of CB muscle was lower than CV and higher than CC. CB contained more monounsaturated fatty acids than CV and CC. Zn content was higher in CB breast than CV and CC. CB, obtained by crossing CV and CC, has partial advantages over both the breeds suggesting that these characteristics aligned with standards to breed ducks with high-quality meat.

Abstract
Maintaining a robust immune system and safeguarding the liver from toxins are crucial for overall health. The study aimed to investigate the immunostimulant effects of papaya seed-enriched cakes (CPS) in countering carbon tetrachloride (CCl4)-induced immunocytotoxicity in rats (n = 48). The rats were divided into six groups (8 each): a control group (Group 1), rats fed cakes containing 15% papaya seeds (Group 2 - CPS), rats exposed only to CCl4 (Group 3 - CCl4), rats injected with CCl4 and administered silymarin (Group 4 - CCl4 + S), rats receiving both CCl4 and cakes with papaya seeds (Group 5 - CCl4 + CPS), and rats receiving both CCl4 and silymarin with papaya seed-enriched cakes (Group 6 - CCl4 + CPS + S). HPLC analysis of papaya seeds revealed the presence of ten polyphenol compounds, with quercetin, apigenin, and catechin identified as major flavonoids, along with pyrogallol, ellagic, and gallic acid as predominant phenolic acids. These compounds displayed potent antioxidant activity, attributed to the seeds' high total phenolic and flavonoid content. The administration of CCl4 significantly affected hematological parameters, liver enzymes, hepatic oxidative stress, levels of TNF-α, IL-6, IgG, as well as IgM. However, rats fed with CPS exhibited mitigation of CCl4-induced toxic effects on hematological parameters and hepatotoxicity. CPS consumption enhanced the antioxidant system, improved inflammatory markers, and immune parameters, restoring them to normal levels. Histopathological analysis confirmed CPS's ability to reduce CCl4-induced hepatocellular necrosis. Immunohistochemical assessment further revealed reduced immunoreactivity against cleaved caspase-3 expression and increased COX2 immunoreactivity, indicating hepatocellular regeneration in CPS. The combination of CPS and silymarin demonstrated even more notable improvements, suggesting augmented protective impacts against CCl4-induced immunosuppression and hepatotoxicity. In conclusion, CPS exhibited antioxidant properties and effectively protected against CCl4-induced immunotoxicity and hepatotoxicity, with additional benefits observed when combined with silymarin. These findings emphasize the potential health advantages of incorporating papaya seeds into food products, promoting immune system health, and safeguarding against liver damage induced by hazardous agents like CCl4.

Abstract
Objective This study aimed to identify multifaceted factors affecting intake of dietary supplements among Koreans. Methods Korean National Health and Nutrition Examination Survey (KNHANES) data from 2018 to 2020 were obtained, pertaining to functional food intake, health related behaviors and morbidities. A total of 12,031 participants representing the Korean adult population were identified into two groups: 1 year more consumer group (N = 4,345) vs. non-consumer group (N = 7,686). A logistic regression analysis was performed to analyze the predictors of dietary supplement consumptions. Results Sociodemographic variables were associated with dietary supplement use. Participants who were female (odds ratio [OR] = 1.85; 95% CI, 1.59-2.15), older (OR = 1.06; 95% CI, 1.04-1.08), married (OR = 6.39; 95% CI, 3.44-11.85), highly educated, and high income earners consumed significantly more dietary supplements. Non-smoking (OR = 1.27; 95% CI, 1.06-1.53) and performing aerobic exercise (OR = 1.28; 95% CI, 1.13-1.46) predict dietary supplement consumption. Self-rated health status and health-related quality of life increased the likelihood of dietary supplement intake by 1.86 (OR = 1.86; 95% CI, 1.04-3.32) and 7.77 times (OR = 7.77; 95% CI, 1.66-33.40), respectively. The number of chronic diseases, cancer, or stroke was not significantly associated with intake. Those with obesity tended to less consume dietary supplements (OR = 0.85; 95% CI, 0.74-0.97). Hypertension (OR = 3.14; 95% CI, 1.36-7.21), osteoporosis (OR = 1.47; 95% CI, 1.11-1.95), and asthma (OR = 0.44; 95% CI, 0.27-0.73) were significantly associated with the intake. Conclusion Considering that healthy behaviors and subjective health led to the consumption of dietary supplements, whereas current disease or catastrophic experience did not, the intake of dietary supplements should be included in health promotion in Korea.

Abstract
The organic food industry has significantly gained currency due to consumers being increasingly health conscious. However, more insight is needed to decipher the impact of organic food consumption on consumer well-being. Quantitative methods using a cross-sectional design were applied to collect data from 578 organic food consumers residing in South Africa. The results revealed that organic food consumption plays a central role in providing pleasure, positive emotions, a sense of accomplishment and personal growth to consumers. Moreover, the findings indicate that consumers' health consciousness significantly influences the interplay between dimensions of well-being. These findings shed important light on the scholarly debate around the influence of sustainable consumption on well-being. The study also provides crucial insights into new strategies that actors in the organic food industry as well as policymakers will use to effectively promote sustainable consumption and a healthy lifestyle.

Abstract
With the growing demand for sustainable practises, the food industry is increasingly adopting circular economy approaches. One example is recycling the symbiotic culture of bacteria and yeast (SCOBY) used in kombucha fermentation to create value-added products. However, consumer acceptance of such novel products remains unclear. To address this, the present study examined consumer attitudes towards ice cream made with SCOBY as an ingredient and how this affected their intention to consume it. Drawing on the theory of planned behaviour (TPB) and additional constructs such as emotions and food neophobia, an online survey was conducted with New Zealand consumers (N = 170). Results showed that the TPB constructs significantly predicted the intention to consume SCOBY ice cream. Moreover, by adding emotions to the constructs, the model's explanatory power was enhanced. Attitudes, subjective norms, and emotions were the main predictors of intention, which in turn was found to be the main predictor of behaviour. Participants' beliefs about the safety and taste of SCOBY ice cream were significantly correlated with their intention and behaviour, as were the opinions of nutritionists/dietitians, friends, and family. The model accounted for 21.7% of the variance in behaviour and 57.4% of the variance in intention. These findings can be used to plan marketing strategies related to waste-to-value-added products such as SCOBY ice cream.

Abstract
Managing the health of migrants has become a crucial aspect of promoting social harmony and cohesion in China. This study investigates the impact of public health education on the health status of migrants in China using cross-sectional data from the China Migrants Dynamic Survey 2017. A total of 169,989 migrants in China were selected as samples for empirical test. Data were analyzed using descriptive statistics, logistic regression, and the structural equation model. The findings show that health education significantly influences the health status of migrants in China. Specifically, health education related to occupational diseases, venereal diseases/AIDS, and self-rescue in public emergencies had a significant positive impact on migrants' health, while health education regarding chronic diseases had a significant negative impact. Health education delivered through lectures and bulletin boards had a significant positive impact on migrants' health, but online education had a significant negative effect on the health status of migrants. The effects of health education differ by gender and age, with a stronger positive impact on female migrants and elderly migrants aged 60 and above. The mediating effect of health behaviors was significant only in the total effect. In conclusion, health education can effectively enhance the health status of migrants in China by modifying their health behaviors.

Abstract
It is evident that over-consumption of meat can contribute to the emission of hazardous greenhouse gases. One viable way to address such climate impact is to make people become more aware of more sustainable diet options, such as cultivated meat. However, it is challenging to instigate change in people's meat-eating habit, and empirical works have been examining the psychological factors that are related to consumers' willingness to consume cultivated meat. Research has suggested that psychological well-being can play a role in the meaning-making of food consumption, with higher well-being individuals showing more recognition of other sociocultural benefits of consuming food beyond just fulfilling their sustenance needs. As existing works have yet to understand the link between well-being and consumption of novel foods, the current research set out to fill this gap by examining the relationship between people's psychological well-being and their willingness to consume cultivated meat via different reasons (mediators) for consuming cultivated meat. We recruited a representative sample of 948 adults in Singapore to complete an online survey. The study offered the first evidence that there is a positive relationship between people's psychological well-being and their willingness to consume cultivated meat. Further, results revealed that their higher willingness can be motivated by the perception that cultivated meat is as healthy and nutritious, as safe as, and has the same sensory quality as real meat, and is beneficial to the society. This investigation adds to the growing literature on consumer acceptance of cultivated meat by showing the novel finding that well-being and receptivity to cultivated meat is positively linked, and such a positive link can be explained by people's better recognition of the prospective benefits offered by this alternative food.

Abstract
Two different meat emulsions were prepared with different physical stability: R1 with 6.28 ± 1.13% total expressible fluid and R2 with 17.7 ± 1.48%. The emulsions were placed in plastic casings at three different surface tensions (ST), expressed as contact angle, and three distinct overstuffing percentages (OS). The stuffed samples were cooked in an industrial oven. After cooling, purge losses (PL) and texture profile analysis (TPA) were measured. The reduced surface tension of the plastic casings significantly decreased the PL of both recipes. In the case of R2, a combination of high OS and low ST was necessary to reduce PL in a 60%. In the case of TPA, OS had a statistical influence on parameters like chewiness, cohesiveness, and hardness. Plastic casings with different surface tension (to increase adherence of meat emulsion to the casing) stuffed at different levels of overstuffing percentages (to reduce free space between meat emulsion and casing) represent a potential tool to reduce PL of products based on low stability meat emulsions.

Abstract
Purpose The COVID-19 pandemic, which involving mass quarantines in many nations, has affected consumer health consciousness behaviors, including food consumption. This study aimed to investigate the impact of COVID-19 anxiety on functional food consumption within the framework of changes in health concerns and electronic word-of-mouth communication through digital platforms, paying special attention to the moderating effect of trust on eWOM information. Design /methodology/approach: This cross-sectional study included 527 participants. The data were analyzed using a structural equation modeling approach. Mediating moderating effects were tested using bootstrapping and multigroup methods. Findings Anxiety about the COVID-19 virus has a great impact on individuals’ health concerns, word-of-mouth information seeking, and functional food consumption intention. Mediating effects of health consciousness and eWOM on functional food consumption intention were also observed. The anxiety about the COVID-19 virus and health consciousness triggers eWOM communication, and is a strong driver of intention to purchase functional foods if people trust the eWOM information source. Originality/value While scholars have demonstrated the impact of COVID-19 on human behavior, a largely uninvestigated issue is the effect of COVID-19 virus anxiety on health product consumption. This is one of the first studies to examine the interrelationships among COVID-19 anxiety, health consciousness, eWOM, and functional food consumption intention. This study provides valuable insights into consumer behavior during the COVID-19 pandemic. Future research should consider the effect of COVID-19 virus anxiety on health-related issues and nutritional behavioral consequences. Based on the results, implications for managers and researchers are proposed. Covid-19 virus anxiety impact individuals’ concern of health and functional foods consuming intention. eWOM communication mediate the effect of anxiety of Covid-19 virus and functional foods consuming intention. Trust on eWOM information moderates these relations.

Abstract
In recent years, enormous amounts of spent mushroom substrate (SMS) have been generated because of the rapid development of mushroom production. Since the conventional disposal methods of these residues can cause serious environmental problems, alternative waste management techniques are required to ensure sustainable agriculture. However, SMS might be not suitable for vermicomposting when used alone. Therefore, the primary purpose of this study was to investigate the effect of Azolla microphylla (Azolla) biomass, eggshells, fruit peels, and cassava pulp on the biodegradation process of SMS. The results showed the treatments supplemented with cassava pulp and fruit peel waste improved the growth of earthworms, while the carbon-to-nitrogen ratio of these vermicomposts decreased significantly (p < 0.05) due to the improved total nitrogen contents (7.64 g kg-1 and 6.71 g kg-1). Concerning the degradation process and the vermicompost quality, the addition of these agro-residues facilitated the enzyme activities (cellulase, urease, and alkaline phosphatase) and increased the total macronutrient (P, K, Mg, and Ca) and phytohormone (fruit peel waste: AA, GA3, and cytokinin; cassava pulp: cytokinin) contents of the final products compared to the control treatment. On the other hand, Azolla had no additional effect on the fecundity and growth of Eudrilus eugenia. Meanwhile, the treatment supplemented with eggshells was high in Mg (7.15 g kg-1) and Ca (305.6 g kg-1). Overall, the combined decomposition of SMS-based bedding material with Azolla, eggshells, fruit peel waste, and cassava pulp resulted in mature organic fertilizers with improved chemical properties.

Focusing on the physical appearance of the food itself, and limiting the focus on shape to the concept of symmetry, this research investigated how food shape influences consumer perceptions of healthiness and naturalness and their subsequent food preferences. By conducting three empirical studies involving self-reported preference and trade-off choices, this research verified that it is a two-staged process of naturalness and healthiness that mediates the main effect of symmetry on foods preference. Furthermore, the incremental perceived unhealthiness of food would mitigate the positive effect of food symmetry. These findings are meaningful for food marketing managers and policymakers when making food-related decisions.

Abstract
The purpose of this article is to investigate the factors that influence consumers’ intention to purchase organic food in Egypt. Given the novelty of organic food marketing in developing countries, much of the factors that influence its consumption are still inadequately explored in the marketing literature. A conceptual model of the factors that impact the consumption of organic food was developed based on the theory of planned behaviour and previous literature in the area of food consumption. To test the conceptual model and to validate the research hypotheses, an online questionnaire was adopted to collect data from 363 consumers in Egypt. The partial least square structural equation modelling (PLS-SEM) approach was used to analyse the data. The findings indicated that purchase intention of organic food is influenced by consumers’ attitudes and environmental concern. However, e-WOM, subjective norms, perceived behavioural control and health consciousness did not influence consumers’ purchase intention. Conversely, the results showed that e-WOM had a significant influence on consumers’ attitudes, subjective norms, perceived behavioural control, health consciousness and environmental concern. This article contributes by presenting the factors that affect organic food purchase intention in Egypt, and it provides some recommendations for marketing organic food in developing countries.

Vrgović P, Pojić M, Teslić N, Mandić A, Kljakić AC, Pavlić B, Stupar A, Pestorić M, Škrobot D, Mišan A. Communicating Function and Co-Creating Healthy Food: Designing a Functional Food Product Together with Consumers. Foods 2022; 11:foods11070961. [PMID: 35407048 PMCID: PMC8997572 DOI: 10.3390/foods11070961] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2022] [Revised: 03/16/2022] [Accepted: 03/18/2022] [Indexed: 01/13/2023] Open
Abstract
Functional food is lately an interesting topic from the new product development perspective; complex motivation and expectations of consumers regarding it present a challenge when new products are designed. Co-creation is an interesting alternative to the standard practices by the R & D departments since it directly involves consumers in the various stages of the creation process. This work aims to describe experiences of engaging consumers in different development stages of a functional food product within a project realized at a food research institute. Four consecutive studies were conducted: the first study explored current trends in Serbia regarding the way consumers use functional food and are informed about it; the second study described development of a raspberry seeds extract with antioxidant and anti-proliferative activity confirmed in vitro; the third study tested the same extract in a sample of consumers, validating its usability in food products; and the fourth study described a co-creation session with 18 participants, during which a number of activities were realized to stimulate idea generation. Rather than the final product idea itself, this work is valuable because of detailed insights into the various phases of the co-creation process. It is shown that consumers and food researchers can together engage in the new food product development process as long as the communication between them is rich and with mutual understanding.

Abstract
Sustainable certifications communicate the environmental benefits of food products to consumers, and allow producers to differentiate their products from conventional ones. This study expands existing knowledge on fish consumers by assessing the importance of sustainable certifications in fish selection. A best–worst analysis was applied to a convenient sample of Italian household members responsible for food shopping, segmented with a latent class clustering model based on their socio-demographic characteristics, fish purchase behaviors, as well as attitudinal features. The results show that sustainable certifications were of interest to consumers, as more than 1 out of 10 respondents valued sustainable certifications in purchasing fish. Respondents interested in sustainable certifications on fish were medium-aged consumers, with high working status, well educated, as well as living in a medium-size household without children. These consumers were more interested in organic foods and had an interest in food nutritional information; they likely have a healthy holistic lifestyle, and may purchase organic food, including fish, to improve their health by increasing their physical well-being.

Abstract
Objective This study was designed to determine the antioxidant activity of the extracts of beetroot by using beetroot energy drink and flavored milk (products). Material & Methods. This experimental trial was conducted at Jinnah University for Women, Pakistan, under the approval of local institutional review board number JUW/DFST/RCB010/2020. All the materials such as beetroot, carrot, cucumber, and lemon were obtained commercially from which two products were formulated: beetroot energy drink (sample1) and flavored milk (sample 2). These formulated products were evaluated for quality analysis (pH and brix), phytochemical screening using the Keller-Kiliani test, Salkowski's test, Alkaline reagent test, lead acetate test, ferric chloride test, protein test, quantitative test of phenol, antioxidant activity, sensory analysis, and shelf life study. The paired t-test was applied to detect significant differences between two samples. Results The phytochemical analysis revealed that cardiac glycosides, phytosterol, flavonoids, and terpenoids were found in both energy booster drink (EBD) and flavored milk (FM) except phenolic compounds that were found only in EBD. The antioxidant capacity of beetroot juice was far greater than FM. The statistical sensorial analysis of FM and EBD reported a significant mean difference between most of the groups with p < 0.0001. Conclusion This study concludes that energy drinks having beetroot indicated higher antioxidant capacity than flavored milk. The nutraceutical products (energy booster drink and flavored milk) containing beetroot are enriched with optimum quantities of proteins and fats and low carbohydrates at a stable pH with an adequate total energy content.

Abstract
Ageism refers to stereotyping (how we think), prejudice (how we feel), and discrimination (how we act) against people based on their age. It is a serious public health issue that can negatively impact older people’s health and quality of life. The present protocol has several goals: (1) adapt the Ambivalent Ageism Scale for the general Portuguese population and healthcare professionals; (2) assess the factorial invariance of the questionnaire between general population vs. healthcare professionals; (3) evaluate the level of ageism and its predictors in the general population and evaluate the level of ageism and its predictors in healthcare professionals; (4) compare the levels of ageism between groups and the invariance between groups regarding the explanatory model of predictors of ageism. This quantitative, cross-sectional, descriptive, observational study will be developed in partnership with several Healthcare Professional Boards/Associations, National Geriatrics and Gerontology Associations, and the Universities of the Third Age Network Association. The web-based survey will be conducted on a convenience sample recruited via various social media and institutional channels. The survey consists of three questionnaires: (1) Demographic data; (2) Ambivalent Ageism Scale; (3) Palmore-Neri and Cachioni questionnaire. The methodology of this study will include translation, pilot testing, semantic adjustment, exploratory and confirmatory factor analysis, and multigroup analysis of the Ambivalent Ageism Scale. Data will be treated using International Business Machines Corporation (IBM®) Statistical Package for the Social Sciences (SPSS) software and Analysis of Moment Structures (AMOS). Descriptive analysis will be conducted to assess the level of ageism in the study sample. The ageism levels between the two groups will be compared using the t-student test, and two Structural Equation Modeling will be developed to evaluate the predictors of ageism. Assessing ageism is necessary to allow healthcare professionals and policymakers to design and implement strategies to solve or reduce this issue. Findings from this study will generate knowledge relevant to healthcare and medical courses along with anti-ageism education for the Portuguese population.

Abstract
This paper focused on eggs enriched with omega-3-fatty acids with the aim of understanding if functional eggs were of interest to Italian consumers, and analyzing which characteristics of table egg quality, consumers’ attitudes and socio-demographic characteristics affect the consumers’ willingness to pay (WTP) a premium price for eggs enriched with omega-3-fatty acids. We performed an online survey on 312 Italian consumers. The analysis was based on the Tobit regression model. The findings showed that unmarried females were more willing to pay a premium price for functional eggs than male consumers. Furthermore, the probability of showing a higher WTP for functional eggs increased among consumers reporting a higher income. Moreover, the WTP for functional eggs increased with the growing importance that people attributed to items such as the size of eggs, rearing type, feed given to chickens, and the provenience and brand of eggs. These results suggested that consumers need to have clear information about functional eggs. As expected, WTP for functional eggs decreased with increasing neophobia and food techno-neophobia factors. In conclusion, the findings showed an interesting potential for eggs enriched with omega-3-fatty acids, which seems to be a product with high possibility to be greatly appreciated on the market, especially if accompanied by a good, informative campaign for increasing people’s knowledge level.

Abstract
Background: the context and purpose of the study Unhealthy food consumption has raised an alarming situation of obesity among Asian nations and posing serious threats to human health. Recent studies have acknowledged that organic food consumption has been contrariwise associated with obesity. The consumption of healthy food has received research attention in social marketing and several antecedents and consequences have been identified. However, to date, there is a void in literature that how social, individual, and marketing elements together tradeoff in predicting a healthy lifestyle. Thus, the current investigation unfolds the antecedents of healthy foods’ adoption in Asia by integrating the brand signaling and theory of planned behavior. Methods The data of 241 respondents were collected from selected social media Facebook communities through a survey using assessed 42 questions. For this purpose, participants’ Facebook accounts were selected from the online healthy communities such as ‘Diet Suku Suku Separuh’ (469,000 followers), ‘Hiking, and Camping around Malaysia’ (351,200 followers), and ‘Healthy Malaysia’ (332 followers). The enumerator also engaged with the online community by liking posts and following health accounts. Results The data was analyzed using PLS (SEM) approach, the outcomes of hypotheses revealed interesting information that health consciousness not significantly predicts the purchase intention of healthy food. All antecedents were significant contributors to the prediction of foods’ purchase intentions in this study. However, the findings indicated that no positive relationship exists between brand image identifications and brand credibility identifications, and healthy foods’ purchase intentions identifications. The findings also indicated that no positive relationship exists between health consciousness identifications and healthy foods’ purchase intentions identifications. Conclusions: (summary and potential implications) Owing to the perilous increase in obesity among the general public in Asia. This study reinforced the factor that can help in the adoption of a healthy lifestyle. The study validated that a healthy lifestyle is reliant on the consumers’ health consciousness, environmental concern, and innovativeness through motivating the consumers’ healthy foods’ purchase intentions. Surprisingly, the results highlighted that respondents have not identified brand image and credibility as an antecedent of purchase intention. Given that organic food brands are somewhat new in Asian markets and therefore, brands must endure crisis marketing practices to improve their brand recognition. Therefore, policymakers must facilitate the food promotional activities that are critical to enhancing the perceived benefits of organic food to combat issues like obesity. This paper offers a foundation for future empirical investigations in Asia and various stakeholders on how to promote a healthy lifestyle in Asia. Specifically, the results will help policymakers to offer positive policies and procedures for the improvement of a healthy lifestyle through the understanding of the antecedents and consequences of health-conscious consumers’ healthy foods’ purchase intentions.

Abstract
Resumo Com a mudança na alimentação dos adultos nas últimas décadas, aumenta o desenvolvimento de doenças crônicas não transmissíveis. Aumentar o consumo de alimentos funcionais, com ações metabólicas benéficas ao organismo, é uma estratégia para proporcionar benefícios à saúde em longo prazo. O objetivo deste trabalho foi identificar os fatores que têm influência na percepção e no consumo de alimentos funcionais por adultos. Neste estudo, dentre os fatores que interferem no consumo de alimentos funcionais identificados, os aspectos socioeconômicos, de saúde e de qualidade dos alimentos se destacaram. No âmbito geral, apesar de controvérsias, os estudos caracterizam os consumidores de alimentos funcionais como mulheres, de boa situação financeira e alto nível de escolaridade, que se preocupam com a saúde de forma global, na medida em que praticam atividades físicas e têm uma alimentação adequada. Ademais, percebe-se que a cultura local tem bastante influência na percepção dos alimentos funcionais. Alguns fatores, como a familiaridade, sejam do produto, seja da alegação funcional, também são importantes para determinar a atitude do consumidor perante esses alimentos. O sabor é o principal atributo sensorial que define o consumo de alimentos funcionais. Os consumidores também tendem a preferir alimentos que são considerados naturais e não processados. Portanto, estudos que relacionem hábitos globais de saúde e o consumo de alimentos funcionais podem ser interessantes para assim nortear as intervenções e a inovação na produção de alimentos nesta área.

Abstract
Corona Virus Disease 2019 (COVID-19) has led to a reduction in the overall consumption of dairy products in China. How to restore the consumption potential of dairy products and alleviate the serious impact on the dairy market in the post-epidemic period is an urgent problem that needs to be resolved. Based on the survey data of 1780 consumers in 31 provinces (municipalities and autonomous regions) of China, the Heckman two-stage model was used to empirically test the impact of consumer health awareness on dairy product purchase behavior during the COVID-19 pandemic and to further analyze the differences in factors affecting dairy product purchase behavior with the restriction of consumer health awareness. The results showed that the overall level of consumer health awareness after the outbreak of COVID-19 was relatively high. A total of 79% of consumers preferred to buy dairy products after the COVID-19 outbreak, and the proportion of purchased dairy products increased by an average of 17.49%, compared with that before the COVID-19 outbreak. Health change perception, health concern degree, and health habit development in consumer health awareness all have important impacts on the purchase behavior of dairy products. Among them, health change perception and health habit development both positively and significantly affected the purchase intention. Moreover, all three aspects of consumer health awareness positively increased the proportion of dairy product purchases. Difference analysis showed that there were obvious differences among consumer groups with different health awareness in dairy product purchase decisions. Component factor analysis found that, overall, consumer health awareness directly affected the purchase intention and increased the purchase proportion of dairy products. Therefore, policy recommendations are proposed to increase the consumption momentum of dairy products by raising consumer health awareness in the post-epidemic period.

Abstract
Organic food consumption and its effects on health remain understudied in adults and in children. The aim of this study was to describe family characteristics associated with feeding infants organic foods during the complementary feeding period. The analysis included 9764 children from the French Étude Longitudinale Française depuis l'Enfance (ELFE) birth cohort. In addition to telephone interviews conducted at 2, 12 and 24 months, a monthly questionnaire about milk feeding and complementary foods (including organic foods) was completed by parents between 3 and 10 months. Associations between family characteristics and feeding with organic foods during complementary feeding were analysed by multivariable multinomial logistic regression. Overall, 51 % of infants never consumed organic food during the complementary feeding period (up to 10 months), 24 % sometimes, 15 % often and 9 % always or almost always. As compared with infants never fed organic foods, those 'often' or 'always' fed organic foods were born to older mothers, with higher education level or family income, and lower pre-pregnancy BMI. As compared with never-smoking women, women who had stopped smoking before pregnancy were more likely to feed their infant organic foods. Feeding with organic foods was also related to long breast-feeding duration and later introduction to complementary foods. To conclude, associations between feeding with organic foods and family socio-economic position as well as infant feeding practices need to be considered when studying the impact of organic foods on children's health and development.

Abstract
The aim of this study was to find the effect of kale and dietary fibre (DF) on the physicochemical properties, nutritional value and sensory quality of multigrain bars. A recipe of multigrain bars was prepared with the addition of fresh kale (20% and 30%) and DF preparations (apple, blackcurrant, chokeberry and hibiscus). The bars were baked at 180 °C for 20 min. These snack bars, based on pumpkin seeds, sunflower seeds, flaxseed and wholegrain oatmeal, are a high-calorie product (302-367 kcal/100 g). However, the composition of the bars encourages consumption. In addition to the ability to quickly satisfy hunger, such bars are rich in many natural ingredients that are considered pro-health (high fibre content (9.1-11.6 g/100 g), protein (11.2-14.3 g/100 g), fat (17.0-21.1 g/100 g, including unsaturated fatty acids), carbohydrates (20.5-24.0 g/100 g), as well as vitamins, minerals and a large number of substances from the antioxidant group. The addition of kale caused a significant increase of water content, but reduction in the value of all texture parameters (TPA profiles) as well as calorific values. The content of polyphenols was strongly and positively correlated with the antioxidant activity (r = 0.92). In the bars with 30% addition of kale (422 mg GA/100 g d.m.), the content of polyphenols was significantly higher than based ones (334 mg GA/100 g d.m.). Bars with the addition of the DF were characterized by a higher antioxidant activity, and the content of carotenoids, chlorophyll A and B and polyphenols. High sensory quality was demonstrated for all (from 4.8 to 7.1 on a 10-point scale). The addition of fibre preparations was also related to technological aspects and allows to create attractive bars without additional chemicals.

Abstract
Most people tend to think that healthy foods do not taste good. This view could have a negative impact on the taste of the food that people eat for health. However, if health-related information is provided to avoid negative aspects, acceptability may improve. Thus, this study investigated changes in consumers’ sensory perception of thickened beverages before and after the provision of dysphagia-related health information. Sixty young (19–39 years old) and middle-aged (40–64 years old) consumers participated in two experiment sessions conducted one week apart. The first session proceeded without any information and the second provided information about dysphagia and the need for dietary modification before evaluation. Three beverages (orange juice, red bean water, and sports drink) were used in nectar-like (51–350 cP) and honey-like (351–1750 cP) forms; original beverage samples (0%) were used as the control. Consumers were asked about acceptability, liking the flavor, intensity, and general health interest (GHI). An analysis of variance was performed to show the change in flavor rating and acceptability between the two sessions. Although there were age-related differences in response to the samples, thickened beverages were rated as more acceptable, in terms of their characteristics (swallowing, viscosity, and mouthfeel) after the information was provided. There were no significant differences for the 0% samples. The mean GHI values were 3.97 ± 0.85 and 4.81 ± 0.68 for the young and middle-aged groups, respectively. High and low GHI groups were analyzed. The high GHI group showed significant differences in acceptability in the informed evaluation, whereas the low GHI group was not influenced by the information.

Abstract
This review provides insight into consumer attitudes toward functional food (FF), with the purpose of better understanding the needs and behavior regarding this kind of product. A total of 47 articles were selected for this paper. The available studies from last 20 years differ according to the focus (awareness, attitudes, motivations, willingness, acceptance by consumers) and methodologies used. Several factors, including socio-demographic, cognitive and attitudinal ones, seem to be serve as the basis for the acceptance of functional products. The research papers showed that nutritional knowledge is the most important of these. Older people are more interested in functional products than younger consumers, because of their stronger belief in the health benefits of FF. Moreover, women are more open to compromise between taste and health properties. Claims concerning the disease preventative properties of FF are the most attractive for consumers. This review focuses also on future perspectives for the functional food market. Adequate knowledge and evidence-based communication seem to be the most promising ways to increase consumers’ interest in these kinds of products.

Fortifying wellbeing: How Chinese consumers and doctors navigate the role of functional foods. Appetite 2021; 164:105296.

Abstract
China's rapidly developing economy has seen an increase in medical problems commonly associated with affluent lifestyles such as increases in metabolic diseases and digestive issues. One response to this problem is an increase in the amount of functional foods currently available, which may take a Western food form, or be more closely associated with traditional Chinese medicine (TCM). This research seeks to understand how functional food and wellbeing intersect in order to better understand how consumers perceive the complex construct of wellbeing, and their agency in its creation. Interviews and Focus Group Interviews were undertaken in Shanghai, China; with consumers who self-identified as having health concerns, and with Doctors trained in Western Medicine and in TCM. Using an iterative process, the primary objective was to holistically examine how consumers navigate the role of functional foods in relation to their wellbeing. Our findings reveal three broad intersecting themes: (1) self-managed therapy using functional foods; (2) building trust with knowledge sharing; and (3) the importance of functional food heuristics. Functional food was not simply considered to be food with an added benefit, but also a cultural symbol of agency over one's wellness. These findings are discussed and implications for both policy makers and marketers are deliberated.

Abstract
Upcycled ingredients are one of the most significant current trends in the food industry aimed to tackle the challenge of solid food loss reduction. This study investigates the potential market among Millennial consumers for products enriched with upcycled ingredients in Italy. We surveyed a sample of 317 Italian Millennial consumers, using a web-based survey. 62% of respondents declared to be informed about the existence of food made from upcycled ingredients and 53% declared to be willing to buy this novel food. Also, 69% of respondents think that food enriched with upcycled ingredients can bring environmental benefits, while only 40% believe that it can bring health benefits. Using a logit model to analyse consumer preferences, we found that food neophobia and food technology neophobia negatively impact on the likelihood of being willing to buy food produced with upcycled ingredients. Also, consumers who give high importance to food certification are less likely to be willing to buy upcycled foods. Contrariwise, reading labels and believing that upcycled foods are healthier or more environmentally friendly positively impacts on the willingness of Millennial consumers to buy these foods. Results for the sample analysed eventually suggest that giving right information to consumers about the environmental and health characteristics of the products, through clear labelling, could increase their market uptake thus helping to reduce food loss and contributing to reaching circular economy objectives in the agricultural sector.

Abstract
A new type of multigrain snack has been designed containing varied additions of Moldavian dragonhead (Dracocephalum moldavica L.) seeds. The antioxidant properties and the general health benefits of this plant material have already been widely acknowledged. The research discussed herein aimed to investigate the influence of the formulation and expansion method (frying) on the content of polyphenolic compounds, individual phenolic acids, and antiradical properties of innovative snacks enriched with dragonhead seeds. The highest content of polyphenols (0.685 mg GAE/mL), free phenolic acids (47.052 µg/g of dry matter), and highest radical scavenging activity (96.23% towards DPPH) were found in the fried snacks enriched with 22% of seeds. In these samples, 11 phenolic acids were detected. Strong positive correlations were seen between the addition of dragonhead and the polyphenol content (r = 0.989) and between the quantity of the enriching additive and the content of free phenolic acids (r = 0.953). The research has shown that such innovative snacks have the potential to supply health-benefiting free phenolic acids, e.g., salicylic, isoferulic, ferulic, p-coumaric, vanillic. Our studies provide an introduction to the development of a new range of functional foods.

Designed to Be Noticed: A Reconceptualization of Carbon Food Labels as Warning Labels. SUSTAINABILITY 2021.

Abstract
Carbon labels are considered a fundamental tool for reducing emissions associated with grocery products. Although the prior literature has shown that both limited motivation and understanding of carbon labels explain the effectiveness of carbon labels, knowledge regarding how to improve the label design to increase noticeability is limited. Given the limited motivation of mainstream consumers to use carbon labels, this exploratory paper proposes that the label design should trigger bottom-up (or sensory-driven) attention mechanisms. Using grounded theory for the data collection and analysis of six focus groups, this study tests six features (i.e., location, size, color, icons, a colored background or border, and textual anchors) and identifies four design criteria (i.e., vividness, incongruity, simplicity, and clarity) that may increase label noticeability. The main conclusion of this qualitative study is that carbon labels are noticed when they are perceived as a cue of hazard. Based on this finding, we propose that carbon labels could be designed as warning labels; therefore, the insights already proven in the warning label literature should be applied to carbon label design to increase its noticeability and use.

Abstract
Understanding consumer food preferences can provide agribusinesses with a competitive advantage through meeting consumers’ needs. Consumers’ preferences for food attributes have been extensively examined, focusing on specific aspects of attributes with specific food products. It is less clear how consumers evaluate the relative importance of the key food attributes in general. Applying the commonly adopted classification of food attributes into endogenous attributes (i.e., safety and freshness) and exogenous attributes (i.e., genetically modified (GM)-free and organic), the relative importance of these attributes for consumers was investigated. Furthermore, the heterogeneity of preferences was explored to identify distinct subgroups of consumers who may differ in valuing various food attributes. An online survey of 489 city dwellers in Australia revealed that the endogenous attributes were regarded as the most important in an order of safety and freshness. The exogenous attributes were rated as much less important. Three profiles with distinctive preferences for food attributes were identified: Not Fussy (12% of participants), Quality First (49%) and Choosy (39%). The findings suggest that consumers value the importance of various food attributes in a hierarchical order, and there is significant heterogeneity in consumers’ food preference. The implications of these findings are discussed in the context of food policy and agribusiness decision-making.

Abstract
In functional food advertising, messages are not always easily understandable for the target audience. Current European legislation, enforced through Regulation 1924/2006, specifies that such messages should be clear and precise so as not to mislead the consumer. The objective of this study was to observe consumers' understanding of messages in functional food advertisements. The methodology used was a self-administered survey filled out by 191 students enrolled in a Degree in Advertising and Public Relations at the University of Alicante (Spain). The results suggest that a large number of students do not know what functional food is and obtain information about these products mainly from labelling/packaging. The major means of communication through which they learn about health benefits via advertising is the internet, followed by television. Most respondents indicated that they understood related advertisements and found it helpful to be given additional information on health benefits. Worthy of note, the greater their level of understanding of the messages, the higher their level of distrust of advertising messages, which they considered to be deceptive or misleading.

Abstract
Prior research suggests inconsistent relationships between individuals' personality traits, time perspective, and specific behavior. In a large representative sample of Norwegian consumers (N = 810), we investigated the relationships between the Big Five personality traits, domain-specific consideration of future consequences (CFC), and consumption of functional foods. Structural equation modeling was employed to test the hypothesized associations. Both CFC-Future and CFC-Immediate were positively related to the consumption of functional foods, whereas personality traits exerted no direct influence on consumption. Several significant associations between personality traits and CFC-Future and CFC-Immediate were found, and three of the five personality traits-Conscientiousness, Agreeableness, and Neuroticism-exerted indirect effects on consumption frequency via CFC-Future. Results support an integrative and hierarchical understanding of how personality traits and time perspective interact in explaining variation in functional food consumption. The findings support the notion that (domain-specific) CFC is better conceptualized as two distinct-albeit related constructs-that are shaped, in part, by broader personality traits.

Abstract
In the last few years, literature data have reported that health status is related to the consumption of foods rich in polyphenols, bioactive compounds found in the plant world, in particular in vegetables and fruit. These pieces of scientific evidence have led to an increase in the demand for functional foods and drinks enriched in polyphenols, so that plant materials are more and more requested. The availability of food and agricultural wastes has adverse effects on the economy, environment, and human health. On the other hand, these materials are a precious source of bioactive compounds as polyphenols. Their recovery and reuse from wastes are according to the circular economy strategy, which has introduced the “zero waste concept.” However, the process is convenient from an economic and environmental point of view only if the final products are standardized and obtained using sustainable and industrial technologies. In this panorama, this paper describes an industrial and sustainable platform for the production of micronized powders and extracts enriched in polyphenols from Olea europaea L. and Vitis vinifera L. wastes that are useful for food, cosmetics, and pharmaceuticals sectors. The platform is based on drying plant materials, extraction of polyphenols through membrane technologies with water, and, when necessary, the concentration of the final fractions under vacuum evaporation. All powders and extracts were characterized by high-performance liquid chromatography–diode array detector–mass spectrometry analysis to define the qualitative and quantitative content of bioactive compounds and insure their standardization and reproducibility. The chromatographic profiles evidenced the presence of secoiridoids, flavones, flavonols, anthocyanins, hydroxycinnamic acids, catechins, and condensed tannins. An overview of the biological activities of the main polyphenols present in Olea europaea L. and Vitis vinifera L. powders and extracts is reported because of biomedical applications.

Abstract
Milk consumption has been on the decline for decades. Part of the cause for this is due to changes in consumer behavior and interest in healthy eating. The aim of this study was to estimate the premium price that consumers are willing to pay for A2 milk. A2 milk is a newcomer type of product containing only A2 beta-casein that is spreading in many countries of the world as a functional food. In addition, it is produced by traditional breeds of cattle that are adapted to the marginal areas and could be a virtuous model of the sustainable management system to which the consumer lately seems to turn in an increasingly conscious way. To accomplish this aim, contingent valuation has been used, which permits using a survey and a direct estimation of the premium price that consumers are willing to pay (WTP). The question format used is a dichotomous choice valuation based on a double-bound model. Statistical analysis was carried out using descriptive statistical analysis. The empirical results reveal that consumers are willing to pay a premium for A2 milk. In addition, individuals interested in product quality and already buying functional products are attracted to this type of product.

Community Supported Agriculture as a Driver of Food-Related Well-Being. SUSTAINABILITY 2020. [DOI: 10.3390/su12114516] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 12/15/2022]
Abstract
Background: There is a growing amount of research interest to understand the role of food in well-being. The demand for community supported agriculture (CSA), bringing people spatially, economically, and socially closer to food, is continuously expanding. CSAs play an important role in both sustainable agriculture practices and influencing consumers’ food-related practices, but yet have received little attention in well-being research. Methods: This study explores food-related well-being among CSA members by using an exploratory, qualitative research design and a thematic analysis of semi-structured interviews. Results: The findings stress the relevance of psychological, social, and spiritual aspects of food-related well-being beyond the nutritional characteristics of food in CSA. Conclusion: The role of sustainable agriculture in contributing to food-related well-being becomes particularly evident based on consumers’ experiences. These results are important in convincing people that their food-related experiences belong to their perceived well-being as well as stimulating people to elevate their multidimensional expectations in relation to food.

Abstract
Bacterial EVs have been related to inter-kingdom communication between probiotic/pathogenic bacteria and their hosts. Our aim was to investigate the transcytosis process of B. subtilis EVs using an in vitro intestinal epithelial cell model. In this study, using Confocal Laser Scanning Microscopy, we report that uptake and internalization of CFSE-labeled B. subtilis EVs (115 nm ± 27 nm) by Caco-2 cells are time-dependent. To study the transcytosis process we used a transwell system and EVs were quantified in the lower chamber by Fluorescence and Nanoparticle Tracking Analysis measurements. Intact EVs are transported across a polarized cell monolayer at 60-120 min and increased after 240 min with an estimated average uptake efficiency of 30% and this process is dose-dependent. EVs movement into intestinal epithelial cells was mainly through Z axis and scarcely on X and Y axis. This work demonstrates that EVs could be transported across the gastrointestinal epithelium. We speculate this mechanism could be the first step allowing EVs to reach the bloodstream for further delivery up to extraintestinal tissues and organs. The expression and further encapsulation of bioactive molecules into natural nanoparticles produced by probiotic bacteria could have practical implications in food, nutraceuticals and clinical therapies.

Abstract
The growth of diet-related diseases is becoming an important societal concern and a challenge for a more sustainable society. This has developed important trends in food consumption, including the increasing demand for food with a natural attribute and with health claims (e.g., enriched food). Consumers tend to evaluate these two attributes as superior ones and tend to pay a premium price for them. Accordingly, the value added by producers also will upturn if they take into consideration the consumers’ preferences. However, to the best of our knowledge, consumer preference over the two types of products (natural and enriched) is not yet completely clear. The present study tries to contribute to reducing this gap by analyzing Hungarian consumer preferences for natural fruit juices over enriched ones and exploring the drivers which guide consumer choices for the two attributes. For this purpose, we analyze young consumers’ willingness-to-pay (WTP) for natural and enriched fruit juices using a seemingly unrelated regression (SUR) to derive the two value-added activities. Our results show that the fruit juice with the natural attribute is preferred over the enriched one, and that there is a common feature behind the perception of the two attributes, namely the healthiness. Based on the natural fruit juice characteristic, these results open space for local production in gardens or in small-medium sized farms. This could have beneficial effects, both for sustainable development of rural areas and for the promotion of healthy food systems towards sustainability in food consumption.

Abstract
This study was conducted to identify the sensory characteristics of six blended teas containing different ingredients and analyze penalty factors for the products based on consumer acceptance, check-all-that-apply questions, and the just-about-right scale. Ten trained panelists created a descriptive set of 23 sensory attributes, and 93 consumers participated in the tests. The attributes were analyzed by classifying them as per appearance, odor/aroma, flavor/taste, texture/mouthfeel, and any aftertaste. Principal component analysis results showed that the blended teas were differentiated by artificial fruit flavor. According to the results of this study, the ideal products should be relatively sweet, mild, fruit flavored, and not too bitter, astringent, pungent, and strong or do not have fermented flavor; astringency is the most troublesome attribute. The consumers preferred teas that were less bitter and less astringent and did not leave the tongue coated with powder; therefore, these attributes were believed to act as drivers of "dislike."

Some Key Factors Affecting Consumers' Intentions to Purchase Functional Foods: A Case Study of Functional Yogurts in Vietnam. Foods 2019; 9:foods9010024. [PMID: 31881653 PMCID: PMC7023454 DOI: 10.3390/foods9010024] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2019] [Revised: 12/20/2019] [Accepted: 12/22/2019] [Indexed: 11/16/2022] Open
Abstract
The development of functional foods is key to promoting a healthy diet and preventing certain diseases. This study aims to examine several key factors that affect consumer attitude and intention with respect to purchasing functional foods in an emerging market economy. A research model was developed by extension of the Theory of Reasoned Action (TRA), and then validated through obtaining data from 596 Vietnamese consumers who were interested in functional yogurts using an interviewer-administered questionnaire. Multivariate data analysis reveals that while health consciousness and subjective norm significantly enhance consumers’ attitudes towards purchasing functional yogurts, perceived price of functional yogurts exerts a negative impact on such attitudes. Moreover, subjective norm and attitude appear to be key predictors of consumers’ intentions to buy functional yogurts. These findings extend the extant literature relating to functional food purchase and consumption in emerging markets, and they have several important practical implications for functional yogurt manufacturers, retailers, and policymakers. A major implication is that education and communication programs that aim at increasing consumers’ health consciousness and their awareness of functional foods’ health benefits play an integral role in the success of functional food products such as functional yogurts. Research limitations and future research directions are also presented.

Relationships Between Health and Environmental Information on the Willingness to Pay for Functional Foods: The Case of a New Aloe Vera Based Product. Nutrients 2019; 11:E2781.

Abstract
There is an increasing interest in healthy and sustainable product characteristics. Consumers determine their dietary intake and frame production systems with their choices. However, little is known about the relationships between health and environmental information in influencing these choices, especially when considering functional foods. This study assessed the influence of health-related and environmental-friendliness-related product information on the willingness to pay (WTP) for functional foods. To this end, a WTP elicitation experiment was set up using a jam-like fruit compote enriched with Aloe vera gel. Participants were provided with different messages related to the health and environmental benefits of Aloe vera products, and were also asked to taste the product. Results indicated that providing new information significantly increased the WTP for the enriched compote. This increase was significant for both health and environmentally based benefits, with the health message leading to a higher WTP. Combining health and environmental messages produced an additive effect on WTP which was independent of the sequential order in which the two messages were given. Results contrasted the view that health messages are the main drivers of WTP, and open a broader range of communication in terms of marketing strategies and sustainable policy objectives.

Abstract
Ishophloroglucin A (IPA), a component of Ishige okamurae (IO), was previously evaluated to standardize the antidiabetic potency of IO. However, the potential of IPA as a functional food for diabetes prevention has not yet been evaluated. Here, we investigated if 1.35 mg/kg IPA, which is the equivalent content of IPA in 75 mg/kg IO, improved glucose homeostasis in high-fat diet (HFD)-induced diabetes after 12 weeks of treatment. IPA significantly ameliorated glucose intolerance, reducing fasting glucose levels as well as 2 h glucose levels in HFD mice. In addition, IPA exerted a protective effect on the pancreatic function in HFD mice via pancreatic β-cells and C-peptide. The level of glucose transporter 4 (GLUT4) in the muscles of HFD mice was stimulated by IPA intake. Our results suggested that IPA, which is a component of IO, can improve glucose homeostasis via GLUT4 in the muscles of HFD mice. IO may be used as a functional food for the prevention of diabetes.
