Claiming health in food products

Health-related information is increasingly used on food products to convey their benefits. Health claims as a subcategory of these messages link the beneficial component, functions or health outcomes with specific products. For consumers, health claims seem to carry the message of increased healthiness, but not necessarily making the product more appealing. The wording of the claim seems to have little impact on claim perception, yet the health image of carrier products is important. From consumer-related factors the relevance and attitudes towards functional foods play a role, whereas socio-demographic factors have only minor impact and the impact seems to be case-dependent. Familiarity with claims and functional foods increase perceived healthiness and acceptance of these products. Apparently consumers make rather rational interpretations of claims and their benefits when forced to assess the information, but we still know relatively little about consumer understanding of the message content in claims and even less about the assessment of personal relevance of the claimed benefits. In future studies more emphasis should be put on including contextual influences and realistic conditions in assessing consumer understanding and use of health claims in purchase decisions.     

Nutrition and Health Claims as Marketing Tools

European regulations mandate that only substantiated and approved statements can be used as nutrition- and health-related claims in food marketing. A thorough understanding of consumer perceptions of these approved claims is needed to assess their impact on both the purchase intention of functional foods and the development of innovative functional food concepts. In this paper, a conceptual framework on the European consumers’ perception of nutrition and health claims on these functional foods is proposed. Through a literature review, common independent variables are structured, and an analysis of these variables shows that nutrition and health claims are mostly only perceived positive by specific target consumers (who need the product, accept the ingredient, understand the benefit, and trust the brand). These consumers indicate that the products with substantiated and approved claims help them in reaching overall health goals. This increased expectation in functional efficacy may mediate an increase in repurchase intent, overall liking, and the amount consumers are willing to spend. Other consumers, however, may have adverse reactions towards nutrition and health claims on functional foods. Implications for the consumer and the industry are discussed.     

Perceived relevance and foods with health-related claims

Although consumer perception of the health claims and nutrition information has been studied widely there is relatively little understanding about the motivational factors underpinning claim perception. The objective of this study is to investigate how levels of perceived relevance influence consumers’ responses to health claims that either promise to reduce a targeted disease risk or improve well-being in comparison to other types of health-related messages, and how attitudes towards nutritionally healthy eating, functional food and previous experience relating to products with health claims affect the consumers’ perceptions of nutrition and health claims. The data (N = 2385) were collected by paper and pencil surveys in Finland, the UK, Germany and Italy on a target group of consumers over 35 year old, solely or jointly responsible for the family’s food shopping. The results showed that relevance has a strong influence on perceptions of personal benefit and willingness to buy products with health claims. However the impact of relevance is much stronger when the health risks are relevant to self than when it is relevant to those close to oneself, especially when the claim promises a targeted risk reduction with detailed information about function and health outcome. Previous experience with products with health claims and interest in nutritionally healthy eating promoted the utility of all claims, regardless of whether they were health or nutrition claims. However, to be influenced by health claims consumers also need to have a positive attitude towards functional food products.     

The role of time constraints in consumer understanding of health claims

The growing market for healthy foods has contributed to increased interest in communicating the health-related benefits of food products. Health claims are becoming an increasingly used instrument to communicate such benefits. In the European Union, consumer understanding of health claims was set as condition for use in order to protect consumers against misleading claims. However, consumer understanding has received little attention compared to consumer perceptions of claims. Consumers only have limited time in a normal shopping situation, which can impact the meanings they attach to claims. This study’s aim was to examine the effect of time constraints on consumer understanding of health claims and the potential link between understanding and intention to buy. A survey conducted among respondents in Denmark (N = 1483) used a time constraint manipulation and varied the health claim shown to respondents when assessing consumer understanding. The results showed that consumers’ objective understanding is lower under time constraint. Specific inferences were associated with increased intention to buy. Implications for public policy and food industry are discussed.     

Opportunities for product innovation using authorised European Union health claims

For authorisation of a health claim in Europe, applicants must follow the procedures in the legislation and in the guidelines for submission of a dossier, as well as the guidance in the European Food Safety Authority's opinions on the scientific requirements for health claims. In addition to the authorised functional benefits of the vitamins and minerals, certain foods and food constituents offer beneficial physiological effects that extend beyond traditionally accepted nutritional effects. The elucidation of these effects is becoming more important, as reflected by the increasing amount of nutrition research and number of product innovations. Provided that they are scientifically substantiated, health claims linked to food and food supplement products can help consumers make well‐informed food choices. The present review focuses on scientific substantiation and consumer understanding of health claims, and it aims to help those involved in academic research, food product development and consumer education about food and health.     

Healthy food is nutritious,but organic food is healthy because it is pure: The negotiation of healthy food choices by Danish consumers of organic food

There is increasing demand for organic food products throughout the Western world. Health concerns have frequently been found to be the main motivation of consumers purchasing organic products, but the literature on consumer preferences and behavior is less clear about what ‘health’ means to consumers of these products, and because of this it remains unclear what exactly drives consumers to choose organic products. This article investigates health from the perspective of consumers, and analyzes negotiations of, and justifications behind, their consumption preferences. The analysis is based on a focus group study conducted in Denmark in 2016. Three different understandings of health can be found when consumers explain their preferences for organic products: Health as purity; Health as pleasure, and a Holistic perspective on health. The first two are familiar from the literature on food. The third, which reflects principles behind organic agriculture, is less documented in the context of consumption. Health as purity was the dominant understanding of health used by the participants when explaining why they purchased organic food products. When participants discussed healthy eating in general, detached from a specific context, most employed a purely nutritional perspective as a definitive argument in supporting claims about healthy eating. The paper’s findings have implications for future research on organic consumption. They also have practical implications for organic food producers and manufacturers.     

Consumer perceptions of graded, graphic and text label presentations for qualified health claims

On December 18, 2002, the Food and Drug Administration (FDA) announced the Consumer Health Information for Better Nutrition Initiative. The initiative's goal is to make available more and better information about conventional foods and dietary supplements to help Americans improve their health and reduce risk of disease by making sound dietary decisions. It included a rating system to assess the "weight of the publicly available evidence." It assigns one of four ranked levels to the claim thus resulting in qualified health claims. Two phases of research were conducted by the International Food Information Council (IFIC) Foundation. Qualitative research to assess consumer understanding, vocabulary, and familiarity with claims helped with the design and orientation of the second quantitative research phase. The quantitative phase employed a Web-based survey. The claim formats included: report card graphic, report card text, embedded claim text, point-counterpoint, structure/function claim, and nutrient content claim. Respondents were asked to rate the product for perceived strength of scientific evidence provided to support the claim, and questions about the product's perceived healthfulness, quality, safety, and purchase intent. Consumers found it difficult to discriminate across four levels and showed inclination to project the scientific validity grade onto other product attributes. Consumers showed preference for simpler messages.     

Comparison of requirements for using health claims on foods in the European Union,the USA,Canada, and Australia/New Zealand

Nutrition is recognized as one of the leading factors influencing the growing incidence of noncommunicable diseases. Despite society experiencing a global rise in obesity, specific populations remain at risk of nutrient deficiencies. The food industry can use health claims to inform consumers about the health benefits of foods through labeling and the broader promotion of specific food products. As health claims are carefully regulated in many countries, their use is limited due to considerable investments required to fulfill the regulatory requirement. Although health claims represent a driving force for innovation in the food industry, the risk of misleading of consumers need to be avoided. The health claim scientific substantiation process must be efficient and transparent in order to meet the needs of companies in the global market, but should be based on strong scientific evidence and plausible mechanisms of actions, to ensure highest level of consumer protection. The objective of this review is to compare the possibilities for using health claims on foods in the European Union, the USA, Canada, and Australia and New Zealand. In particular, we focused on differences in the classification of claims, on the scientific substantiation processes and requirements for health claims use on foods in the selected regions. Reduction of disease risk (RDR) claims are associated with relatively similar procedures and conditions for use, whereas several notable differences were identified for other types of claims. In all cases, RDR claims must be approved prior their introduction to the market, and only a few such claims have been authorized. Much greater differences were observed concerning other types of claims.     

The Impact of Regulation on Informing Consumers about the Health Promoting Properties of Functional Foods in the U.S.A.

ABSTRACT: Functional foods are intended to help consumers manage or reduce disease risks or support the structure or function of the body. In the U.S.A., the term functional food is an intellectual concept that has not been defined in either statute or regulation. Functional foods are treated as conventional foods for purposes of determination of safety and, as such, are subject to the same regulatory approval process. Interest in and demand for more information concerning the health promoting properties of foods and dietary supplements has steadily increased. However, inequities in the regulatory process including the differing treatment of efficacy claims for dietary supplements and functional foods, confusion between structure/function, health claims, and qualified health claims, and the constraints of severely limited resources have all had an impact on the delivery of accurate information to consumers. Although their efforts are coordinated, different agencies view efficacy claims differently, employing different standards for levels of scientific evidence, and different processes for evaluation. A third-party review process that could provide a consistent and sound scientific basis to the evaluation of the evidence would be desirable. Recent proposals by the U.S. Food and Drug Administration concerning qualified health claims may help consumers get more of the information they need and enable them to make informed decisions.     

Nutrition and health claims: Who is interested? An empirical analysis of consumer preferences in Italy

This paper focuses on nutrition and health claims with the aim of verifying if these claims are of interest to different types of consumers, analysing the key variables that characterise their profiles. We performed a face-to-face survey on 240 consumers in charge of grocery shopping for their household in the Milan area (Italy). The analysis is based on two OLS estimation models. Our results suggest two different profiles for consumers interested in products presenting nutrition or health-related claims. Concerning nutrition claims, the analysis outlined a consumer profile particularly focused on household wellbeing. Females, family with young children, and consumers with a higher nutritional knowledge pay particular attention to such claims. Health-related claims, instead, seem to be of interest for those consumers that are older, with limited income, and with a health condition, namely, the most vulnerable segments of population.     

Consumer valuation of European nutritional and health claims: Do taste and attention matter?

Healthier eating and convenience are two important and often divergent aspects of contemporary diet patterns. With the intention of guiding consumers to make more informed food purchase decisions, policy makers, such as the European Union, emphasize the need to shift dietary patterns toward healthier food by introducing nutritional claims (NCs) and health claims (HCs). The purpose of this study is to (i) explore the impact of NCs and HCs on a healthy food product (yogurt), (ii) investigate consumer choices through a discrete choice experiment (DCE), (iii) examine the role of taste as a key food attribute influencing the purchase decision process, and (iv) explore the visual attention that consumers pay to NCs and HCs. The results from a generalized mixed logit model suggest that there is a relationship between the most highly valued NCs and HCs from the stated preferences and visual attention in terms of fixation count. This relationship affirms that the final product selection is based not only on the type of labeling on the package but also on the visual attention that consumers pay to it. Tasting a healthy food product resulted in negative utility, but greater visual attention attached to NCs and HCs and a lower percentage of attribute non-attendance (ANA).     

Some like it healthy: Can socio-demographic characteristics serve as predictors for a healthy food choice?

Authorising new health claims in Europe will favour the diffusion on the market of a greater number of foods with health claims. This scenario presents new opportunities to promote healthy food choices and launches new challenges to define strategies aimed at promoting products on the market. The literature suggests that our understanding of consumers’ sensitivity to health claims is still fragmented and should be further investigated. Our objective is to study the relationship between choice behaviour, attitudes and socio-demographic characteristics in order to evaluate the effectiveness of consumer characteristics in predicting consumers’ choice of products with health claims. Towards this end, we have conducted a choice experiment for extra-virgin olive oil on a sample of Danish (n = 1024) and Italian (n = 1000) consumers. Applying the latent class approach has enabled us to identify a niche of individuals sensitive of health claims and to characterise them with respect to the rest of the population. The results supply insights for the development of more targeted health promotion campaigns, as well as for actions in food marketing.     

Health Risks and Adverse Reactions to Functional Foods

Functional foods have become increasingly popular with consumers anxious to mitigate the effects of an unhealthy lifestyle or aging. In spite of attractive health claims, these products do not have legal or regulatory status in most countries and are regulated through their health claims. Regulation of functional foods by health claims does not address health risks and adverse effects of these products. In this essay regulatory aspects of functional foods are reviewed along with adverse effects published in the peer-reviewed literature. We detail why the lack of an internationally accepted definition of functional foods places consumers at risk of adverse outcomes. Our review will assist regulatory agencies, manufacturers and consumer groups to assess the benefits and reduce the risks associated with these products.

What determines ingredient awareness of consumers? A study on ten functional food ingredients

Given the importance of consumer awareness of functional food ingredients for healthy food choices, the aim of this study is to explore consumers’ ingredient awareness and the determinants which influence the awareness about functional food ingredients.A sample of 200 German consumers was interviewed via CATI (computer aided telephone interview) during September 2011. The participants have been asked about their specific awareness regarding to ten functional food ingredients. Likewise, determinants like health status and health motivation have been assessed and their influence on the construct “consumers’ ingredient awareness” has been tested by employing structural equation modeling.The study shows that consumers’ ingredient awareness varies throughout the sample. Overall it can be stated, that 19% of consumer awareness about functional food ingredients is explained through the described model based on the following predictors: age, educational level, health status, health motivation and information strategies. Among these factors, consumers’ health motivation seems to have the highest relevance to explain consumer awareness. But also the determinants information strategies as well as the education show a significant influence on consumers’ ingredient awareness. As health motivation shows the highest impact on consumers’ ingredient awareness this study underlines the importance of prevention propensity for healthy food choices.     

Consumer Awareness and Interest Toward Sodium Reduction Trends in Korea

Reduction of dietary sodium intake by lowering amount of sodium in foods is a global industry target. Quantitative information on current consumer knowledge of sodium reduction trends in Korea is unknown. The objective of this study was to quantify the consumer knowledge and awareness of sodium and salt reduction in foods and to characterize consumer interest in health labeling on the food package. Additionally, comparison of consumer knowledge status between Korea and United States was followed. Consumers (n = 289) participated in an internet survey designed to gauge consumer knowledge and attitudes toward dietary sodium, the sodium content in representative food products (n = 27), and their interest toward specific health claims, including sodium labeling. Questions regarding demographics as well as consumption characteristics were asked. Sodium knowledge index and saltiness belief index were calculated based on the number of correct responses regarding the salt level and sodium content in given food products. Kano analysis was conducted to determine the role of nutrition labels in consumer satisfaction with products. Current consumer knowledge on the sodium content in food products was high, and consumers were adept at matching the sodium content with the salty taste intensity of food products. Consumers’ knowledge of the relationship between diets high in sodium and an increased risk of developing previously reported sodium‐related diseases, such as hypertension, coronary heart disease, kidney disease, and stomach cancer, were also high. Information on the nutrition panel that influences the consumer satisfaction (trans‐fat, sodium, ingredient list, and country of origin) as well as adjective‐nutrition claim pairs that appeal positively to purchase intent of the product were identified.     

Shaping up: How package shape and consumer body conspire to affect food healthiness evaluation

Integrating research on human body shapes with studies of health cues in food package design, this research explores how food packages resembling humanoid shapes impact consumers’ evaluation of food healthiness. Adopting a self-referencing perspective, two studies show that packages resembling slim humanoid shapes lead to foods being evaluated as healthier, especially with female consumers whose bodily characteristics mark them as being not thin. Study 1 uses packages designed to mimic humanoid body shapes and shows that slimness effects depend on consumer gender and body mass index (BMI): The heuristic that slim packages contain more healthy foods is more pronounced with women and increasing BMI. Study 2 replicates these findings and offers process evidence for self-referencing as a mediator of the package slimness – healthiness evaluation. Together the findings highlight package shape as an important cue to food healthiness evaluation and aid marketers and designers in better matching packages to target audiences and products.     

Ensuring the future of functional foods

Consumption of functional foods suggests a strategy to reduce the incidence of chronic health disorders. This message has resonated with consumers and driven market growth. Functional food research has significantly increased over the last decade but few studies have addressed the bioavailability of active ingredients for clinical efficacy. Baked goods such as bread, biscuits and cake are popular categories for innovation due to their widespread consumption. These new developments have often impacted on organoleptic properties of the finished products and thus consumer acceptance. Blending of bioactive ingredients may overcome this deficit. However, an understanding of the role of the microbiome in health has indicated that the efficacy of functional foods is unlikely to be uniform within the population. Further growth in the functional foods market, is likely to require greater evidence of the bioavailability of active ingredients, clinical effect and support for health claims by regulators especially in the EU.
