Consumer preference for nutrition and health claims: A multi-methodological approach

Chinese consumers' psychology and behavior of the foods with nutrition claims based on AISAS model

Objective

We analyzed the impact of nutrition claims on Chinese consumer psychology and behavior process based on the theoretical framework of AISAS (Attention-Interest-Search-Action-Share) model.

Design

To adopt questionnaires to collect gender, age, income and other basic information of adult residents and a 5-point Likert scale ranging from 1 (strongly disagree) to 5 (strongly agree) to collect data on residents' attention to nutrition claims, interest in nutrition claims, search on nutrition claim information, purchasing behavior on food with nutrition claims, sharing information on food with nutrition claims. Then to study the relationship between the basic situation of residents and their attention, interest, search, food purchase behavior and sharing of nutrition claims by using exploratory factor analysis, reliability and validity test, structural equation modeling estimation and hypothesis testing.

Participants

Chinese adults.

Setting

Multi-stage stratified random sampling method was used to collect the valid online questionnaire of 630 Chinese adults from Central, North, East, South, Northwest, Southwest, and Northeast China.

Results

Younger adults and those with higher household incomes exhibited heightened attention to nutrition claims. Furthermore, consumers' attention to nutrition claims could be transformed into food information sharing through interest, information search, and food purchase. Consumers' interest in food with nutrition claims could be transformed directly into food purchase. Consumers' search for related information could be directly transformed into food information sharing.

Conclusion

Chinese consumers' age and household income could be included in the AISAS model for the foods with nutrition claims, and the consumers' action and share could transform from their interest and search.

Emotional response to healthier foods: Influence of culture and health consciousness

Sugar, salt, and fat content in processed products are important concerns for consumers. Hence, alternative "healthy" versions of conventional foods such as chocolate, potato chips, and yogurt are offered. This work aimed to define the emotional response of consumers from different cultural backgrounds (Spain vs. Brazil) evoked by healthier versions of conventional products and the relationship between hedonic responses and health consciousness. A total of 186 Brazilian and 152 Spanish consumers participated in this online cross-cultural study. Participants answered a Health Consciousness Questionnaire and an emotional check-all-that-applies questionnaire using picture stimuli of conventional chocolate, potato chips, and yogurt and their healthier versions with less sugar, salt, and fat content, respectively. The Brazilians' emotional responses were more diverse for all stimuli compared to the Spaniards'. However, participants from both cultures rated an average of "slightly agree" on the health consciousness scale; a higher level of consumption, liking, and willingness to buy; and a higher frequency of positive emotional terms for the stimuli of conventional products compared to their healthier versions. A higher frequency of evocation of "active" is strongly associated with higher levels of health consciousness. Strategic actions by the food industry and government must consider cultural, emotional, and health-conscious factors to encourage the consumption of healthier foods. PRACTICAL APPLICATION: Food manufacturers can use the information obtained from this study to create healthier versions of their products that appeal to consumers' emotional responses and health consciousness levels. The findings can assist in designing strategic actions to promote healthier food consumption by emphasizing the benefits of healthier food choices and making them more appealing to consumers. The methodology employed in this study can also be applied to further studies aimed to assess emotional responses to food stimuli across different cultures.

Consumer perception of salt-reduced bread with the addition of brown seaweed evaluated under blinded and informed conditions

BACKGROUND

Many consumers have a high salt intake and bread is a primary source because of its high rate of consumption. The inclusion of seaweeds has been proposed as an ingredient that could help reduce the salt content of food products. As such, the present study aimed to evaluate whether the amount of salt in bread could be reduced and the change in sensory properties be mitigated by the inclusion of brown seaweed. There were two different sensory trials conducted. In the first trial, participants (n = 102) evaluated bread made with brown seaweed (4% substitution for flour) with reduced amounts of salt (10%, 20%, 30%, 40% and 50%). The second trial asked participants (n = 98) to evaluate the control bread and the 20% salt-reduced bread in blinded and informed conditions. In both sensory trials, the breads samples were assessed using hedonic scales, just-about-right scales, and check-all-that-apply.

RESULTS

The results showed that the 10% and 20% salt-reduced breads were acceptable and associated with being soft, chewy and having no aftertaste. The other breads were associated with a dense, dry and strong aftertaste, along with not being salty enough for the consumers. When the breads were evaluated in informed conditions, the salt reduction label had a negative impact on the consumers' liking.

CONCLUSION

The research emphasizes that salt-reduced labels influence consumers' sensory perception. © 2023 The Authors. Journal of The Science of Food and Agriculture published by John Wiley & Sons Ltd on behalf of Society of Chemical Industry.

Identifying Differences in Consumer Attitudes towards Local Foods in Organic and National Voluntary Quality Certification Schemes

As no study on attitudes towards local food has compared "organic" and national quality scheme consumer segments, this study aimed to provide further insights and clarifications on the issue of consumer segmentation in terms of trust towards organic food and food of selected quality perceived as local, along socioeconomic characteristics, and other important determinants of this complex interaction. The research examines consumers' attitudes and perceptions related to two quality schemes for special Slovenian foods: "Organic", which relates to production methods; and "Selected Quality", which relates to quality attributes. The study focused on two segments of consumers, who exhibit a high level of trust towards the two quality schemes. Comparative analysis of the consumer segments looked for the potential differences with respect to their sociodemographic profiles, as well as to their understanding of the definition of local food, attitudes towards local food, trust in actors and institutions, and willingness to purchase local food. The study combined qualitative approaches and a quantitative survey with a general population sample. The results showed that both consumer groups have similar understandings of local food, with region-based interpretations outperforming country-based interpretations. The "Organic" group was more cosmopolitan and supportive of the local community, regardless of geographic proximity, than the "Selected Quality" group. Older consumers occupy a larger share of both segments, with professionals and individuals with higher incomes more likely to be in the "Organic" group and retirees and students more likely to be in the "Selected Quality" group. To increase the consumers' interest in food with the "Organic" and "Selected Quality" schemes, more specific product propositions should be developed.

The Impact of Time on Nutrition and Health Claims on the Irish Marketplace

Since the implementation of Regulation (EC) No 1924/2006 on nutrition and health claims (NHCR) made on food, only 261 health claims have been authorised, suggesting that the regulation creates challenges for the food industry. This study looks at the prevalence of nutrition and health claims labelled on food on the Irish market. Specifically, we compared their prevalence in 2009 with those present on the marketplace in 2022. Food labels of defined food categories were examined in three nationwide supermarkets in Ireland, and data of claims made on these labels were collected. A series of statistical analyses was conducted to compare the results from 2021 with those of 2009. In 2021, around half of the examined products (52.8%) displayed at least one nutrition claim, showing no significant difference with the data collected in 2009 (53.5%). Individual categories, however, did exhibit changes between the two time points. The prevalence of health claims on food has decreased from 21.6% in 2009 to 10.5% in 2021. There will always be a time lag between when a regulation is enacted and what its true impact can be measured. This study provides these data for the impact of time on EU Regulation 1924/2006 on the Irish market.

Increase consumers’ willingness to pay a premium for organic food in restaurants: Explore the role of comparative advertising

Offering organic food is a new trend in the hospitality industry seeking sustainable competitiveness. Premiums and information barriers impede continued growth in organic consumption. This study aims to explore the role of comparative advertising (CA) in organic food communication. Three empirical studies were used to verify the effect of CA vs. non-comparative advertising (NCA) on consumers’ willingness to pay a premium (WTPP) for organic food, examining how benefit appeals (health vs. environmental) and consumers’ organic skepticism affects CA. The results indicate that matching CA and health appeals increase consumers’ WTPP, while environmental appeals have no significant differences between the CA and NCA groups (Study 1). Information persuasiveness mediates the interaction between CA and benefit appeal on WTPP (Study 2). CA increases WTPP among consumers with high organic skepticism, while the interaction between CA and health appeal is only effective for low skepticism consumers (Study 3). The findings unravel and explain the mechanics of how CA works in organic products, which can help restaurants, retailers and tourist destinations advertise organic food to increase consumers’ WTPP.

Young adult preference analysis on the attributes of COVID-19 vaccine in the Philippines: A conjoint analysis approach

Objective

Vaccines are utilized to prevent the severity of illnesses like the COVID-19 virus. Currently, there are a lot of COVID-19 vaccines available in the market like Pfizer, Moderna, AstraZeneca, Johnson and Johnson, and Sinovac. This research aimed to analyze the preference on the existing vaccine attributes of COVID-19.

Study design

Specifically, this study considered 7 attributes such as cost, brand, recommendations, efficacy, side effects, vaccine type, and dose.

Methods

A conjoint analysis with orthogonal design was utilized and 865 respondents were participated.

Results

The result showed that consumers considered brand as the highest attribute, specifically Pfizer and Moderna among other brands. Moreover, the efficacy of 90% and higher were the preferred vaccine with 1 in 100 patient side effects reported. It was seen that safety and effectiveness is the priority in choosing a COVID-19 vaccine. Interestingly, the knowledge and understanding of the COVID-19 vaccine was found to drive consumer's preference for the vaccines available.

Conclusions

The findings of this study could be utilized by the government to increase the willingness to be vaccinated. Lastly, the result of this study would pave a way to promote herd immunity to help fight the COVID-19 pandemic worldwide.

Effects of Low-Calorie Nutrition Claim on Consumption of Packaged Food in China: An Application of the Model of Consumer Behavior

More and more packaged products in China have been labeled as low-calorie products since the official implementation of nutrition claims in 2007. But little was known about the impact of such claims on the Chinese consumption of low-calorie food on the background of increasing rates of obesity among the Chinese population. This study sought to fill the gap by applying a consumer behavior model to a nationally representative online survey by means of structural equation modeling. The findings revealed that nutrition claims significantly affect the consumption of low-calorie products. Specifically, marketing stimulus on low-calorie products first affected consumer psychology, then consumer decision-making, and finally consumer responses. Despite the significant role of consumer psychology and decision-making in consumption, consumers were susceptible to the influence of targeted marketing strategies for foods with a low-calorie claim. It is recommended that appropriate use of low-calorie nutrition claims by manufacturers and choices of low-calorie food by consumers according to their own needs should be encouraged.

Promoting Sustainable Lifestyle Habits: “Real Food” and Social Media in Spain

Obesity and state of being overweight are beginning to be treated as global epidemics. In this context, health professionals are increasingly acting as expert opinion leaders that use social media to connect with the public, in order to promote healthy lifestyles and provide specific recommendations for different product categories, including fresh, processed, and ultra-processed meat products. This study investigates how exposure to content created by health professionals, and posted on social media, influences consumers’ attitudes. For this purpose, the collaboration of one relevant nutritionist influencer in Spain has been obtained. The online survey created has provided 4.584 responses, received from followers (from May to June 2019). After applying a partial least squares path modeling approach, the results suggest that trust in the content shared, the perceived credibility of the professional sharing the information and the informative value, determine the strength with which consumers acquire more knowledge about endorsed products, develop a favorable predisposition towards them, prefer them over their options, and modify their behaviour by purchasing them, instead of their usual foods. The link is stronger, in the case of trust and influencer’s credibility, than for informative value. However, the latter has an indirect effect on the attitude phases through the former.

The impact of COVID-19 on consumers' eating and purchasing habits of agricultural products in China: key determinants and policy implications

BACKGROUND

The study looks at a changed in consumer's eating and purchasing habits during COVID-19 period. There are several modes of transmission but transmission through food as being speculated is one area that has not been confirmed through research. The study, therefore, looks at how speculations about COVID-19 spreading through food has affected consumers' eating and purchasing habits. This study through probit model analysed how consumers' eating and purchasing habits have been influenced.

RESULTS

The result shows that age, gender and education have negatively influenced consumer's eating and purchasing habits during the COVID-19 pandemic compared to pre-pandemic period. The preference for imported food items, preference for frozen food, been infected or knowing someone who has been infected by the virus, and been infected through agricultural source or knowing someone who has been infected by the COVID-19 through agricultural source have negatively affected consumers' eating and purchasing habits compared to pre-pandemic period. The result, however, suggests that consumers who trust in the cold-chain food systems ability to limit the spread of the COVID-19 still maintain a positive eating and purchasing habits.

CONCLUSIONS

The study provides evidence on the impact of COVID-19 on consumer's eating and purchasing habits. Therefore, there is the need to institute proper sanitary measures, especially at cold-chain food systems to help curb the spread and also boost consumers' confidence.

Consumer Preferences and Socioeconomic Factors Decided on Plantain and Plantain-Based Products in the Central Region of Cameroon and Oyo State, Nigeria

Plantain is a key staple food in Central and West Africa, but there is limited understanding of its market in Africa. In addition, the cooking methods for enhancing the nutritional value, consumer preference, and willingness to pay for plantain and plantain-based products are not well understood. The knowledge gaps in the market and consumer dimension of the food chain need to be known to increase plantain utilization and guide breeding efforts. This research contributes by examining the cooking methods, consumer preference, and willingness to pay for plantain and plantain-based products in Cameroon and Nigeria. A household survey sample of 454 Cameroonian consumers in four divisions of Central Region and 418 Nigerian consumers in seven government areas of Oyo State in southwest Nigeria was the basis for the analysis. The results showed some levels of similarity and difference in the consumption and cooking of boiled, roasted, and fried plantain in both countries. The trend in consumption of all plantain-based products was constant in Cameroon but increased in Nigeria. The most important factor influencing Cameroonian consumers’ choice of plantain and its products was taste, while the nutrition trait influenced Nigerian consumers. Both Cameroonian and Nigerian consumers considered packaging, location of produce, and size and quantity as the least important factors. In addition, socioeconomic characteristics were significant determinants of consumers’ choices to consume plantain and its products. Gender significantly influenced (p < 0.05) taste, while nutrition was significantly driven (p < 0.05) by education and annual income. Household size played a significant role (p < 0.05) in consumers’ choices when the price was considered. These findings serve as a guideline to improve existing products to match the needs of consumers in each country and develop products for different consumer segments and potentially increase production.

Nutrition and Health Claims Spectra of Pre-Packaged Foods on Serbian Supermarket Shelves: A Repeated Cross-Sectional Study

Nutrition and health claims (NHCs) are a powerful tool that influence consumers' final decision on the choice of food products. The purposes of this repeated cross-sectional study were to (i) assess the prevalence of pre-packaged food products containing nutrition and health claims among different food categories, (ii) to determine the type of NHCs labelled on the examined food products, and (iii) to evaluate the trend in the use of NHCs in comparison to the 2012 survey. The survey was conducted immediately before the full enforcement of the new national legislation on NHCs in 2020. It comprised 3141 pre-packaged food products from 10 product categories. In total, 21.2% of food products contained any claim (19.4% contained any nutrition claim; 8.2% contained any health claim). In comparison to the 2012 survey, we observed a rising trend in the presence of NHCs; the use of nutrition claims on food products increased three times and the use of health claims increased 1.3 times in the 2020 survey. Bearing in mind that NHCs are a powerful tool guiding consumers' food purchase decisions, NHCs should be supported by precise legislation and strict surveillance by the public health authorities.

Health gains through loss frames: Testing the effectiveness of message framing on citizens' use of nutritional warnings

The aim of the present work was twofold: (i) to evaluate the effect of nutritional warnings and health-related packaging cues (nutrient claim and images of natural foods) on consumers' food choices, and (ii) to evaluate the influence of two types of messages (gain-framed and loss-framed) aimed at encouraging the use of such warnings and packaging cues on food choices. A total of 510 participants were recruited using an advertisement on Facebook and Instagram targeted at Uruguayan adult users. Participants were randomly allocated to one of three experimental groups: control (n = 167), loss-framed messages (n = 177) and gain-framed messages (n = 166). Then, they completed a choice-conjoint task involving packages of crackers differing in three variables: nutritional warnings (present vs. absent), nutrient claim (present vs. absent) and images of seeds and wheat (present vs. absent). Warnings were the most relevant package element driving choices, even when participants were not exposed to any type of message. Exposure to loss-framed messages led to changes in the relative importance attached to the package characteristics, whereas gain-framed messages did not. Graphic pieces conveying messages encouraging the use of nutritional warnings by stressing the negative consequences of excessive consumption of sugar, fat, and sodium increased the relative importance attached to nutritional warnings and decreased the relative importance attached to health-related cues (nutrient claims and images of seeds and wheat). These results suggest that public awareness campaigns aimed at encouraging citizens to use nutritional warnings should emphasize the negative health consequences of excessive intake of sugar, fat, and sodium.

C. B, Shrestha S. Evaluation of nutritional supplements prescribed, its associated cost and patients knowledge, attitude and practice towards nutraceuticals: A hospital based cross-sectional study in Kavrepalanchok, Nepal

BACKGROUND

There is substantial increment in nutraceutical consumption in Nepal, although the data on its efficacy and safety is scarce. The practices of nutraceutical supplements users in Nepal remain undocumented. Therefore, this study was conducted to study the prescription pattern, cost, knowledge, attitude and practice (KAP) of the patient towards nutraceutical.

METHODS

Descriptive cross-sectional study with stratified purposive sampling (n = 400) (patients from the out-patient departments of Scheer Memorial Adventist Hospital, Kavre, Nepal) was performed using a validated structured questionnaire assessing the socio-demographic characteristics, knowledge, attitude, practice of nutraceutical and total cost patients spent on nutraceutical alone. Pearson Chi-square test (x2) was used to investigate the association between socio-demographic variables and patients' KAP (knowledge, attitude and practice) towards nutraceutical. One way ANOVA was performed to compare the cost of nutraceutical among the different outpatient departments.

RESULTS

More than 80% of patients were found to be consuming nutraceutical on their own. The mostly prescribed nutraceutical were vitamins (40.7%), minerals (23.7%), enzymes (21.1%), proteins (8.8%), probiotics (4.2%) and herbals (2.0%). With the most common reasons for consuming nutraceutical were to maintain good health (70.0%) and healthcare professionals (57.85%) were the most approached source of information for nutraceutical. Nearly half of the patients (46.5%) had an inadequate level of knowledge whereas more than two-third (71.5%) showed a moderate positive attitude towards nutraceutical use. The average amount patients spent was NRs.575.78 [equivalent to USD 4.85] per prescription on nutraceutical alone. The maximum cost amounted to NRs 757.18 [equivalent to USD 6.43] in Orthopedics, and the minimum cost was NRs 399.03 [equivalent to USD 3.36] in Obstetrics and gynecology, respectively. There was a significant difference (p <0.001) in cost of nutraceutical prescribed between the OPD clinics.

CONCLUSION

The higher prevalence of inadequate knowledge despite moderate positive attitude towards nutraceutical among patients regarding some significant issues such as safety and interactions of nutraceutical consumption and its' substitution for meals reflects the need to develop an educational strategy to increase general public awareness on the rational use of nutraceutical.

Environmental Behavior Spillover or Public Information Induction: Consumers' Intention to Pay a Premium for Rice Grown with Green Manure as Crop Fertilizer

Nowadays, there is a growing interest in pro-environmental foods produced by pro-environmental practices. However, consumers’ payment motivations towards such foods are currently poorly understood. This manuscript provided a critical investigation of Chinese consumers’ intention to pay a premium (ITPP) for rice grown with green manure as crop fertilizer (GMR). One focus was the establishment of an explanatory structural research framework that includes effects of environmental behavior spillover (EBS) and public information induction (PII); another focus was to analyze the impacts of the selected structural elements on ITPP by introducing education as a moderator. Results suggest that consumers’ ITPP can be largely influenced by PII, therefore, for GMR marketers and policy makers, measures should be developed to widen consumers’ access to public information related to GMR and to improve their capacity of screening effective information. EBS, when ITPP remains low, emerged as a pivotal predictor of consumers’ ITPP. This observation provides us with the enlightenment that breeding consumers’ daily environmental behaviors is highly valued to inspire their payment intention in the early stages of GMR market development. Another finding is that, with the introduction of the educational variable, the influence coefficients of EBS and PII on ITPP increased from 0.42 and 0.53 to 0.61 and 0.66, respectively, which means that it is possible to boost consumers’ payment intention by improving their educational attainment. This study contributes to the existing literature by providing empirical evidence for the GMR industrial upgrading strategy and have significant implications for the environmental governance of the agricultural sector.

Consumers’ and Farmers’ Perceptions in Europe Regarding the Use of Composted Bedding Material from Cattle

By-products like sawdust and straw are applied in compost bedded-pack barns (CBP) for cattle. These materials, which are gradually mixed with excreta and undergo a composting process, serve as a lying bed for the cattle. This study aims to assess the perception of consumers and farmers regarding the use of CBP during the grazing season of cattle for raising other animals or for growing food crops. This was examined by combining surveys with consumers from eight European countries and cattle farmers, focus groups with consumers, and in-depth interviews with individual farmers who implemented alternative uses of compost. The results showed that farmers preferred the compost bedded-pack system to the cubicle system in terms of sustainability and market aspects, although the cost of the bedding material required for CBP was seen as a significant negative aspect. Around half of all consumers indicated that the compost can be used for non-edible products and 26% indicated the compost can be used for raising other animals. Furthermore, 5% of consumers felt that compost should not be used for any other purpose. There were statistically significant differences between countries; therefore, regional specificities should be taken into account when marketing products from compost in CBP barns.

The Heterogeneity of Consumer Preferences for Meat Safety Attributes in Traditional Markets

In this study, we focus principally on Taiwan’s traditional markets, as food safety issues in those markets have been increasing recently. Thus, this poses pressures and challenges in traditional markets in terms of attracting consumers. This research aims to investigate whether there is consumer demand for more quality improvement from butchers and additional product information in Taiwan’s traditional markets by surveying consumers’ willingness to pay (WTP). This study determines consumers’ preferences for the important attributes and also investigates the different consumer segmentation in Taiwan’s traditional markets by analyzing the types of Taiwanese consumers who care about food safety and additional product information, including Taiwan Fresh Pork (TFP), QR code (provides product source information), Cold storage, and price. In this study, both Mixed Logit Model and Conditional Logit Model are used to elicit consumers’ WTP, and the Latent Class Model is used to understand the market segmentation in Taiwan’s traditional markets. The results show that the majority of Taiwanese consumers in traditional markets show preferences and WTP for meat products if Cold storage and QR code are available in Taiwan’s traditional markets. This work also provides appropriate strategies for improving the additional product information in Taiwan’s traditional markets, which can influence present and potential customers purchasing decisions.

Consumer-perception, nutritional, and functional studies of a yogurt with restructured elderberry juice

We investigated the effects of supplementation of yogurt with elderberry juice (Sambucus nigra L.), in both natural and restructured forms, on certain technological, physicochemical, sensory, and health-promoting properties of yogurt, including antioxidant activity and inhibition of angiotensin-converting enzyme (ACE), α-amylase, and α-glucosidase activity. Consumer acceptance of the yogurt-juice products was assessed. Gel-strength restructured elderberry juice retained a spherical shape and most of the juice, despite decreasing in mass from 57.2 to 50.9 g during storage. As a result, yogurt supplemented with 10 and 25% restructured elderberry juice appeared to be more desirable from a sensory and technological perspective than yogurt with natural juice. Yogurt supplemented with restructured elderberry juice had a high water-holding capacity (94.4-96.4%), exhibited no spontaneous whey syneresis, and maintained a dense consistency (up to 5,626 g). Consumer penalty analysis of the just-about-right diagnostic attributes indicated that the flavor of these yogurts may not be sufficiently refreshing. High correlation was demonstrated between ACE inhibition, ABTS, α-amylase, and α-glucosidase in yogurt supplemented with restructured juice. An in vitro gastrointestinal simulation estimated bioaccessibility of antioxidants to be in the range of 62 to 66%. This model fermented yogurt supplemented with restructured elderberry juice is a novel dairy-juice beverage that represents a new approach for the development of functional fruit yogurt beverages.

Current Functionality and Potential Improvements of Non-Alcoholic Fermented Cereal Beverages

Fermentation continues to be the most common biotechnological tool to be used in cereal-based beverages, as it is relatively simple and economical. Fermented beverages hold a long tradition and have become known for their sensory and health-promoting attributes. Considering the attractive sensory traits and due to increased consumer awareness of the importance of healthy nutrition, the market for functional, natural, and non-alcoholic beverages is steadily increasing all over the world. This paper outlines the current achievements and technological development employed to enhance the qualitative and nutritional status of non-alcoholic fermented cereal beverages (NFCBs). Following an in-depth review of various scientific publications, current production methods are discussed as having the potential to enhance the functional properties of NFCBs and their safety, as a promising approach to help consumers in their efforts to improve their nutrition and health status. Moreover, key aspects concerning production techniques, fermentation methods, and the nutritional value of NFCBs are highlighted, together with their potential health benefits and current consumption trends. Further research efforts are required in the segment of traditional fermented cereal beverages to identify new potentially probiotic microorganisms and starter cultures, novel ingredients as fermentation substrates, and to finally elucidate the contributions of microorganisms and enzymes in the fermentation process.
