The Influence of a Factitious Free-From Food Product Label on Consumer Perceptions of Healthfulness

The role of culture in the representation of probiotic foods

Functional foods, and specifically probiotics, are important products present in retail worldwide. Probiotics comprise "live microorganisms that, when administered in adequate amounts, can confer a health benefit on the host". This study aimed to investigate the effect of culture on probiotic foods social representation. A total of 818 consumers from seven countries (Argentina, Brazil, Honduras, Mauritius, Mexico, Peru, and Slovenia) participated in the study. A free word association task was performed with the inductor term "probiotic food," followed by lemmatization, categorization, and prototypical analysis of the social representation. The results indicated that the term health was common in all countries studied, as well as other positive aspects such as benefits, well-being, and functional foods. This study helped to shed light and better understand the role of culture in the social representation of probiotics.

Gluten-containing flours and gluten-free flours as a source of calcium, magnesium, iron and zinc

Wheat flour is widely used in Poland for the preparation of bread, pasta and other foods. Due to the increasing number of people diagnosed with diet-related diseases, consumer awareness of health-promoting issues and interest in gluten-free products (GFP). There is a dynamic development of the market for these foods with high quality and nutritional value and minerals that benefit human health and prevent deficiencies in patients on a gluten-free diet. The aim of this study was to determine the content of minerals: Ca, Fe, Mg and Zn in flours using the ICP-OES method. The mineral composition of selected GF flours available on the Polish market was analysed. It was tested how they supplement the mineral requirements compared to gluten-containing flours. It was found that these products can be a valuable source of essential minerals, which are often in short supply, especially in patients with gastrointestinal disorders. As our study has shown, flours from the GFP group are a good source of essential minerals, especially in the case of chia and flax flours, as well as buckwheat, amaranth, quinoa, lupin or almonds flours.

How Many Hungarian Consumers Choose Lactose- and Gluten-Free Food Products Even When They Do Not Necessarily Need to?

The popularity of "free-from" food products (FFFPs), which exclude several ingredients such as lactose, gluten, or sugar, is increasing globally. However, experts agree that avoiding these ingredients without medical reasons can lead to nutritional deficiencies. A representative consumer survey was conducted in Hungary (n = 1002); it focused on behaviors related to FFFPs, particularly lactose- and gluten-free products. This study revealed that consumers often consider "free-from" claims during shopping. Lactose- and gluten-free foods were popular, even among those without specific dietary needs. A distinct "free-from consumer group" (7.8% of the sample, predominantly women) was identified, who consume both lactose- and gluten-free foods frequently. However, only 15.4% of the group had medical reasons for their preference, such as lactose intolerance or gluten sensitivity. The majority (75.6%) chose these products without medical justification, relying on self-diagnosis, through the involvement of family members, or the belief that they were healthier. This consumer group accounts for nearly 6% of Hungary's adult population, exceeding 470,000 individuals. Extrapolating these figures to other European countries suggests that 25-30 million EU citizens might be in a similar situation, highlighting the need for improved health education and awareness-raising campaigns to prevent imbalanced nutrition and foster the recognition and treatment of real health problems.

This cookie will save the planet! The effect of a private sustainability claim on consumers' expectations

Current study investigates whether a private, sustainability claim has an impact on individuals' sensory and non-sensory expectations (halo effect) and quantifies such impact on individual monetary preferences. An incentive-compatible artefactual field experiment was performed by recruiting regular buyers and consumers of the investigated product (cookies). Results reveal that the sustainable agriculture claim generates high (unrelated) expectations and a statistically significant premium price compared to the conventional counterpart. Additionally, these expectations, together with respondents' trust in the claim, are the drivers of the price premium. Findings suggest the need for policy makers and consumer advocates to scrutinize the potential drawbacks of private sustainability claims on food products.

Causes and consequences of fake transparency/excess information in food claims

This study develops novel multi-stage game-theoretic models of heterogeneous firms and consumers in vertically differentiated food product markets with asymmetric information to analyze the economic causes and market and welfare consequences of excess information/fake transparency in food labeling. Analytical results indicate that the firms' incentives to adopt the excess information strategy, the Nash equilibrium configuration of firms adopting the strategy, and the market and welfare impacts of excess information are case-specific and dependent on the consumer reaction to excess information, the quality of the firms' products, the degree of product differentiation between the brand producing firms, and whether the market is covered or not.

Environmental, Health or Social Impacts? Investigating Ethical Food Consumption Behavior in the Case of Palm Oil-Free Foods

Environmental consciousness, health consciousness, social consciousness—today, all three terms have become buzzwords that influence food consumer behavior and reach many consumers. A number of consumer trends have emerged, which manufacturers have responded to, giving consumers the opportunity to make purchasing decisions that reflect any or all of these three buzzwords. In the context of palm oil, all three of these buzzwords may be associated with a consumer-perceived problem. They may be aware of the social (e.g., child labor), environmental (e.g., burning of rainforests) or potential health impacts communicated by the media. Today, more and more products claim to be palm oil free. Related to this the main question of the research is “why do consumers choose palm oil-free foods?” The results of our model using the theory of planned behavior show that the factor most influencing purchase intention is consumer attitude towards palm oil. The only significant effect on this factor is the environmental impact. Neither the perceived health-, nor the social effect had a significant effect on shaping attitudes among the respondents. A further result of the model is that perceived behavioral control only directly affects actual behavior, but does not influence intention, indicating that although there is a possibility for respondents to purchase palm oil-free products, it was not necessarily a conscious, intentional purchase.

Something to chew on: technological aspects for novel snacks

Snacks have accompanied people for a long time, meeting our needs for something fast and filling between meals. Societies and technologies have changed, and so have snacks, adapting to people's daily lives, concerns, and demands. Although traditional snacks, such as potato chips, are still ubiquitous and popular worldwide, there is not unanimity around them anymore, since many people have been looking for healthier snacks. Studies have been carried out to propose healthier snack options by changing their composition and/or techniques to produce them, minimizing contents of energy-dense components and/or maximizing the retention or bioavailability of nutrients. This mini-review presents the main trends on development of snacks and future perspectives. © 2021 Society of Chemical Industry.

Evolution of Milk Consumption and Its Psychological Determinants: A Mini-Review

The consumption of lactose-free products and in particular lactose-free milk is increasing worldwide. Although many studies claim that this dietary trend is mainly determined by the number of lactose intolerant people that is growing, others state that most of them self-report an intolerance that has not been diagnosed by medical tests. However, many researchers reported that the consumption of lactose-free milk may put the consumers' health at risk especially when the subjects are not intolerant. Consequently, understanding this new dietary trend considering its main determinants it is necessary to generate educational and intervention campaigns useful to guide people toward healthier and more adequate eating styles. For these reasons we conducted a narrative mini review to summarize the factors contributing to the consumption of lactose-free milk as an alternative to cow's milk, exploring intrinsic and extrinsic product characteristics, biological and physiological, as well as psychological, situational and socio-cultural factors. This narrative mini-review shows that there are six categories of factors that affect the consumption of lactose-free milk. In particular, the intrinsic aspects linked to the product and the socio-demographic characteristics of the consumer are the most explored. On the contrary, situational and socio-cultural factors are the least studied. Finally, this study argues that there are too few studies that investigates the emotional, identity and social aspects underlying these food choices, suggesting the development of future research that investigate the implicit consumer subjective levers to decipher lactose-free milk consumptions.

Nutritional Composition of Gluten-Free Labelled Foods in the Slovenian Food Supply

The market of gluten-free (GF) foods has been expanding in recent years. GF foods are consumed not only by those with medical predispositions for avoiding gluten, but also by a specific segment of consumers, searching for “healthier” food choices. For these, such practices can present a serious limitation in the variability of food choices. Considering that GF foods are commonly perceived as healthier alternatives, there is a lack of knowledge on the nutritional profile and content of specific nutrients of GF-labelled foods compared to general food supply. A comparison of nutritional composition of GF/non-GF packed foods in the Slovenian food supply was conducted. The nutrient profiling scoring criterion (NPSC) and content of specific nutrients/energy was compared between GF-labelled and regular foods. The highest proportion of GF-labelled products were found in food categories, which typically do not contain gluten (Cheese imitates, Milk imitates, Yoghurt imitates, Canned fish and seafood and Processed meat). Significant differences in the nutrient profile between GF-labelled and regular products were found in Cakes, muffins and pastry, Crisps and snacks, Desserts and Milk imitates. GF-labelled foods often had lower protein and sugar content. Energy value was comparable in most categories and no significant differences in salt content were found, compared to non-GF products. In conclusion, GF-labelled foods will unlikely bring health benefits to those who are not medically required to follow GF diet. Public health initiatives should aim towards promotion of consuming non-processed foods and provision of reliable information about who is required to consume GF foods.

Supermarket Circulars Promoting the Sales of 'Healthy' Foods: Analysis Based on Degree of Processing

The health and wellness food sector grew 98% from 2009 to 2014 in Brazil, the world's fourth-biggest market. The trend has reached supermarket circulars, which recently started to feature whole sections advertising health and wellness-enhancing foods. This study identified food items advertised in circulars' specific sections of two Brazilian supermarket chains (one regional, one national) during a 10-week period. Foods were classified according to degree of food processing and presence/type of claims on their front-of-pack (FoP) labels. Comparison between groups of Unprocessed/Minimally Processed foods vs. Ultra-processed foods and presence/type of claims employed Pearson chi-square test. From the 434 alleged health and wellness-enhancing foods advertised, around half (51.4%) were classified as Ultra-processed. Presence of reduced and increased nutrient-content claims was significantly higher in labels of Ultra-processed foods. Most frequent claims addressed sugar and fibre content. Brazilian supermarket circulars were found to be promoting the sale of Ultra-processed foods in their health and wellness sections, leading to a situation that can mislead the consumer and bring negative health outcomes.

Nutrition, hedonic or environmental? The effect of front-of-pack messages on consumers' perception and purchase intention of a novel food product with multiple attributes

The present study aims to assess the effect of different Front-Of-Pack messages on consumer perception, willingness to buy and willingness to pay for a new food product, with multiple attributes, such as particular nutritional information, sensory characteristics, and a potentially positive environmental impact. Furthermore, this study explores the differences between consumers based on their individual latent traits in order to evaluate how these factors affect the willingness to buy the new product, as well as to outline a profile of target consumers attracted by innovative food products. A consumer survey was conducted on a representative sample of 1250 Italian consumers, using a between-subject design with different Front-Of-Pack messages as stimuli. Messages were related to different attributes: nutrition, environmental impact, hedonic characteristics, and process innovation. Empirical findings show that Front-Of-Pack messages do not directly affect consumer willingness to buy, but they do influence consumer perception of the product. The most effective message is the nutrition one. Consumer willingness to buy is particularly influenced by product perception and by their novelty seeking orientation in consumption. Furthermore, consumers were segmented through hierarchical clustering based on their novelty seeking orientation. The results obtained provide valuable suggestions for the design of new products' labeling and for the outline of the profile of potential target customers for innovative food products.

Role of Food Neophobia and Allergen Content in Food Choices for a Polish Cohort of Young Women

Young women are vulnerable to a number of factors which influence their food choices, including beliefs about food products, or information about nutritional value, while information, that product is free from specific component generates consumer perceptions of its healthfulness. Among the factors which may influence such perception, there is food neophobia (FN). The aim of this study was to determine the influence of FN and information about allergens on the food product choices in the Polish cohort of young women, in the choice experiment when given a model restaurant menu. The web-based choice experiment, in a group of 600 women, aged 18-30 years, with no food allergies diagnosed, was conducted using a mock Italian-style restaurant menu. For 2 starters, 2 soups, 3 main courses and 3 desserts that were included, the allergen content, neophobic potential and perceived lack of healthiness, for a Polish population, were defined. Each respondent randomly received the version containing only a description of dishes, or a description accompanied by the allergens listed. The FN was assessed using the Food Neophobia Scale (FNS). The type of menu (with or without allergens listed) did not influence the choices of dishes. The highest FN level was observed for the women being inhabitants of villages (median of 32). The respondents characterized by a high level of FN less commonly chose dishes characterized by neophobic potential as a starter (Carpaccio), main course (Risotto ai frutti di mare) and dessert (Zabaglione). At the same time, the highest FN level was observed for respondents who chose dishes with no neophobic potential (median of 34.5). However, for allergen content and perceived lack of healthiness, no association with FN was observed, so it may be stated that for neophobic respondents, only neophobic potential is a factor limiting the choice of dishes. It may be concluded that food neophobia in young women may limit the consumption of dishes with unknown food products, and the influence is observed independently of other features of a dish, such as allergen content or perceived healthiness. The problem may appear especially for inhabitants of villages, who are characterized by the highest level of FN.

Recent practical researches in the development of gluten-free breads

Wheat bread is consumed globally and has played a critical role in the story of civilization since the development of agriculture. While the aroma and flavor of this staple food continue to delight and satisfy most people, some individuals have a specific allergy to wheat or a genetic disposition to celiac disease. To improve the quality of life of these patients from a dietary standpoint, food-processing researchers have been seeking to develop high-quality gluten-free bread. As the quality of wheat breads depends largely on the viscoelastic properties of gluten, various ingredients have been employed to simulate its effects, such as hydrocolloids, transglutaminase, and proteases. Recent attempts have included the use of redox regulation as well as particle-stabilized foam. In this short review, we introduce the ongoing advancements in the development of gluten-free bread, by our laboratory as well as others, focusing mainly on rice-based breads. The social and scientific contexts of these efforts are also mentioned.

The Handbook of Minerals on a Gluten-Free Diet

The importance of a gluten-free diet (GFD) in the treatment of celiac disease and other gluten-related disorders is undisputable. However, strict GFD often lead to nutritional imbalances and, therefore, to deficiencies. One of the most common deficiencies from a GFD are an insufficient amount of Ca, Fe, Mg, and Zn. This is mainly because the most of popular gluten-free (GF) raw materials are poor in minerals. Although the popularity of GFD is constantly growing, the data on minerals in GF products are still limited. More importantly, an access to the data is even more restricted. Therefore, the paper reviews the Ca, Fe, Mg, and Zn contents in hundreds of grain GF products available worldwide. The data for 444 products from categories of flours, mixes for cooking, bakery products, cereals, groats, rice, and pasta are obtained from research papers and nutritional databases. The calculation of the realization of mineral requirements from a portion of each product with its graphical classification as rich/average/poor source of each mineral is given. The review is a handbook of minerals for people on a GFD, dietitians, and food producers.

Who Values Gluten-Free? Dietary Intake, Behaviors, and Sociodemographic Characteristics of Young Adults Who Value Gluten-Free Food

BACKGROUND

Over the past decade, consumer demand for gluten-free products has increased, but little is known about the public health impact of and factors correlated with valuing gluten-free food.

OBJECTIVE

Describe the sociodemographic and behavioral characteristics of young adults valuing gluten-free as an important food attribute, and compare their dietary intake with other young adults.

DESIGN

Cross-sectional analysis of survey data collected in 2015 to 2016 as part of the fourth wave of the Project EAT (Eating and Activity in Teens and Young Adults) cohort study.

PARTICIPANTS/SETTING

Population-based sample of 1,819 young adults (25 to 36 years) (57% women, 69% white), initially recruited in Minneapolis-St Paul, MN, public middle and senior high schools.

MEASURES

Valuing gluten-free food, weight goals and weight control behaviors, food production values, eating behaviors, physical activity, and dietary intake.

STATISTICAL ANALYSES PERFORMED

Logistic regression models were used to investigate associations with potential correlates of valuing gluten-free food. For dietary intake, adjusted mean estimates were calculated for those who did and those who did not value gluten-free foods.

RESULTS

Approximately 13% of young adults valued gluten-free food, a characteristic most strongly related to valuing food production practices (eg, organic, locally grown); factors such as Nutrition Facts use and having a weight goal were also related to gluten-free food values. Valuing gluten-free food was related to engagement in both healthy behaviors (eg, eating breakfast daily, eating more fruits and vegetables) and unhealthy behaviors (eg, using diet pills to control weight).

CONCLUSIONS AND RELEVANCE

Young adults valuing gluten-free food generally engaged in healthier behaviors and had better dietary intake; of concern, they were also more likely to engage in unhealthy weight control behaviors. Valuing gluten-free food may be part of a cluster of behaviors representing an interest in making healthier food choices but may also be a marker for unhealthy weight preoccupation and behaviors.

Challenges in gluten-free diet in coeliac disease: Prague consensus

BACKGROUND

New treatments in coeliac disease are being vigorously pursued to either replace or facilitate the difficult-tofollow gluten-free diet.

DESIGN

The present review intends to summarise the challenges in gluten-free diet adherence during the transitional period, as reflected in the last Prague consensus, published in 2016.

RESULTS

The honourable panel members recommended that dietary adherence and the consequences of nonadherence represent key components for discussion in the transitional period setting.

CONCLUSIONS

There are numerous difficulties in adhering to gluten withdrawal, but the transition period from adolescence to young adulthood is considered a fragile and high-risk period for intentional and unintentional gluten intake.

Commercially available gluten-free pastas elevate postprandial glycemia in comparison to conventional wheat pasta in healthy adults: a double-blind randomized crossover trial

Given the popularity of gluten-free diets, research regarding the health implications of gluten-free (GF) products is necessary.
