Chapple CI, Burnett AJ, Woods JL, Russell CG. A Cross-Sectional Study of Sports Food Consumption Patterns, Experiences, and Perceptions amongst Non-Athletes in Australia. Nutrients 2024; 16:1101. [PMID: 38674792 PMCID: PMC11053821 DOI: 10.3390/nu16081101] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2024] [Revised: 03/28/2024] [Accepted: 04/05/2024] [Indexed: 04/28/2024] Open
Abstract
Sports foods are designed for athletes, yet their availability, type, and sales have increased over the past decade, likely driven by non-athlete use. This could lead to detrimental health outcomes via over/misuse or unwanted side effects. The aim of this study was to describe sports food consumption patterns and associated drivers, consumption reasons, perception of risks, and side effects experienced amongst non-athletes in Australia. In 2022, n = 307 non-athlete Australian adults (18-65 years) completed an online cross-sectional survey including closed-ended (consumption patterns, factors, and exercise participation) and open-ended questions (reasons for consumption, risk perception, and side effects experienced). Descriptive statistics (frequency and percent) described the sample. Ordinal logistic regression was used for univariate associations and a multivariate model was used to determine relationships between sports food consumption proxy and significant univariate associations. The themes were analysed via inductive thematic analysis using NVivo 14. Females consumed sports foods most frequently, 65% of participants consumed three or more sports foods, and participants with higher sports food consumption/frequency were less likely to perceive risks or experience side effects. The main reason for consumption was protein intake, digestion/stomach issues were the main perceived risks, and the main side effect was bloating. Despite understanding the risks and side effects, non-athlete consumers continue to use numerous sports foods, which appear to be influenced by sociodemographic factors and packaging labels. Tighter regulation of packaging-label information would ensure safer and more informed consumption.

Effects of Digitalized Front-of-Package Food Labels on Healthy Food-Related Behavior: A Systematic Review. Behav Sci (Basel) 2022; 12:bs12100363.

Abstract
Front-of-package (FOP) food labels may impact healthy food-related behavior. However, such labels may be presented using new technology and they may impact behavior differently than physical labels. This systematic review investigated the effects of physical and digitalized labels on healthy food-related behavior. This review used four search engines to collect articles that investigated the effects of food labels on the purchase, consumption, hypothetical choice, and self-reports of healthy foods. General findings, types of labels, or whether the articles used physical versus digitalized static, interactive, or technology-enabled labels were synthesized. The dependent variables were categorized according to whether they were under full, partial, or no control of the independent variables. The risk of bias was measured by the RoB 2 tool and adapted Joanna Briggs Institute Checklist. The search strategy identified 285 records and 30 articles were included. While digitalized static and physical labels did not differ in their effects on healthy food-related behavior, technology-enabled labels were more predictive of healthy food-related behavior than interactive labels.

Prates SMS, Reis IA, Rojas CFU, Spinillo CG, Anastácio LR. Influence of nutrition claims on different models of front-of-package nutritional labeling in supposedly healthy foods: Impact on the understanding of nutritional information, healthfulness perception, and purchase intention of Brazilian consumers. Front Nutr 2022; 9:921065. [PMID: 36211521 PMCID: PMC9539030 DOI: 10.3389/fnut.2022.921065] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2022] [Accepted: 08/22/2022] [Indexed: 11/13/2022] Open
Abstract
Nutrition claims are positive information about foods, which are widely used as a marketing strategy on labels. On the contrary, front-of-package nutritional labeling (FoPNL) aims to make it easier for consumers to understand the nutritional composition of foods and favor healthy food choices. However, the concomitant presence of nutrition claims and FoPNL may hinder the understanding, judgment, and choices of consumers at the moment of purchase. Therefore, the objective of this study was to evaluate the influence of nutrition claims on the efficacy of FoPNL models in the understanding of nutritional information, healthfulness perception, and purchase intention of Brazilian consumers. It was an experimental cross-sectional study carried out using an online questionnaire, with a total of 720 participants randomly divided into four FoPNL conditions: control, octagon, triangle, and magnifying glass. Each participant looked at 12 food packages, which were produced following the factorial design: (i) food category (cereal bar, whole grain cookies, and snacks); (ii) product type (containing one critical nutrient × containing two critical nutrients); and (iii) nutrition claims (present × absent). The comprehension of nutritional information was evaluated through the identification of excessive nutrients, and the healthfulness perception and purchase intention were evaluated using a seven-point scale. The results indicated that the presence of FoPNL increased the understanding of the information and reduced healthfulness perception and purchase intention. The presence of nutrition claims influenced the three outcomes, decreasing the probability of understanding information about food composition by 32% (OR 0.68, 95% confidence interval 0.58–0.78, p < 0.01) and significantly increasing (p < 0.05) average health scores (1.95–2.02) and purchase intention (2.00–2.05). Nonetheless, the interaction “FoPNL × claims” was not significant, which indicated that claims act independently. All FoPNL models were more effective than the control. For the least healthful type of product (two nutrients in excess), the octagon and triangle models were superior to the magnifying glass, regarding the outcome of healthfulness perception. The results prove the efficacy of FoPNL in consumer understanding and judgment. Despite the positive effects of FoPNL, it did not cancel the positivity bias generated by the claims.

Abstract
High sugar intake in humans is associated with the development of overweight and other diet-related diseases. The World Health Organization and other health organizations recommend limiting the sugar intake to 10% of the total energy intake. There have been different approaches of front-of-pack labelling to reduce the amount of sugar in food products. Companies use nutrition claims to advertise the sugar content (e.g., without added sugar, 30% less sugar). Such nutrition claims can lead to false assumptions about the healthiness of foods and can lead to health-halo effects. Nutrition claims make products appear healthier than they really are, the aspect advertised in the nutrition claim is transferred to the entire food product. As a result, food products can be perceived as healthy even though they are not. Recently, the Nutri-Score was introduced in an increasing number of countries throughout Europe to provide consumers with an overview of the overall nutritional quality of a product. This study analyzes if the Nutri-Score can help to prevent health-halo effects caused by nutrition claims on sugar. Therefore, an online survey consisting of a split-sample design with more than 1,000 respondents was assessed. The results show that, depending on the initial perceived healthiness of a product, the Nutri-Score is able to prevent health-halo effects caused by claims on sugar. Making the Nutri-Score mandatory when using nutrition claims would be one possible way to reduce misperceptions about unhealthy food and reduce health-halo effects caused by claims on sugar.

The Source of Protein or Its Value? Consumer Perception Regarding the Importance of Meat(-like) Product Attributes. APPLIED SCIENCES-BASEL 2022.

Abstract
Food product attributes may significantly influence the general perception of the product itself, as well as the willingness for its consumption. Assessment of the product is based on customers’ beliefs and individual preferences. Because meat-like products are presented as meat substitutes providing sufficient protein values, the present study aimed to determine the effect of protein source and labelling pointing at high protein content on the evaluation of the product. The experimental online study was conducted with a group of 552 respondents. Four versions of product packaging were designed and tested. These packages differed in the presence or absence of the Nutrition Claim and the presence of the text indicating the vegetable or meat origin of the product. Data collected in the experiment were analyzed using a 2 × 2 ANOVA. The study revealed that the source of protein (plant vs. animal) appears to shape consumers’ perception of the product as more eco-friendly (F (1.518) = 38.681, p < 0.001, η2 = 0.069), natural (F (1.518) = 15.518, p < 0.001, η2 = 0.029), and healthy (F (1.518) = 25.761, p < 0.001, η2 = 0.047). Moreover, labelling including a “high-protein” Nutrition Claim increases the willingness to consume the product (F (1.518) = 4.531, p = 0.034, η2 = 0.009), and provides the impression of it being more eco-friendly (F (1.518) = 6.658, p = 0.01, η2 = 0.012) and of a higher quality (F (1.518) = 7.227, p = 0.007, η2 = 0.014). The obtained results may have theoretical significance by improving the understanding of factors determining the perception of food products and the use of meat substitutes.

Appetite 2022; 174:106013.

Abstract
Front-of-pack health imagery can shape people's inferences about food products' health benefits, even leading people to falsely remember reading health claims they never saw. However, research has typically examined these effects in situations where participants have little contextual information to guide their inferences about a product. The present research aimed to replicate the finding that front-of-pack health imagery leads participants to falsely remember reading health claims. It also extends that finding, by exploring whether this effect is moderated by the presence of contextual information signaling the product's actual 'healthiness'. In two pre-registered experiments, participants saw images of fictitious food products accompanied by written nutrition claims. Some of the products contained a health-related image whereas others did not. The supposed 'healthiness' of each product was manipulated by altering the color of the products' multiple traffic light (MTL) label (Experiment 1), or with an explicit healthiness statement (Experiment 2). Participants then attempted to remember the written claims that had appeared on each product's packaging. Health-related images increased participants' tendency to falsely remember reading health claims. But this was true regardless of whether or not participants saw contextual cues about the products' healthiness, either indirectly (Experiment 1) or directly (Experiment 2). These findings suggest that the presence of health imagery on a food product's package can lead consumers to infer health benefits, even when other, more direct cues indicate that the product is unhealthy. This research informs debates on safeguarding consumers from potentially misleading health claims, through the regulation of imagery in food marketing.

Abstract
Responsible marketing (RM) helps companies make products that improve people’s lives and is in line with public policies that provide a positive impact on society; an example of this is traffic light nutritional labelling (TLNL). Ecuador was a pioneer in Latin America in the mandatory implementation of TLNL. For this reason, this research aimed to analyze RM in the TLNL of food products from the perception of consumers in the urban area of Cuenca, Ecuador. Specifically, the research aimed to answer: What is the degree of consumer understanding of TLNL in the urban area of Cuenca, Ecuador? A cross-sectional investigation was undertaken, with 384 surveys conducted. A chi-square test (χ2) was performed, which showed the relationship between variables reflecting RM knowledge and the understanding and use of TLNL. An ordinal logit model (OLM) was applied, showing that the variables of education, knowledge of labeling, and knowledge of marketing were associated with a greater probability of having some level of understanding of TLNL. Finally, a binomial logit model (BLM) revealed that the variables of income level, knowledge of TLNL, illnesses, confidence in TLNL, the influence of COVID-19 on eating habits, and knowledge of marketing were associated with people being more likely to use TLNL. RM is present in the TLNL through the clear and understandable dissemination of information.

Abstract
Individuals perceive organic food as being healthier and containing fewer calories than conventional foods. We provide an alternative way to investigate this organic halo effect using a mirrored method to Choice Experiments applied to healthiness judgments. In an experimental study (N = 415), we examined whether healthiness judgments toward a 200g cookie box are impacted by the organic label, nutrition information (fat and sugar levels), and price and determined the relative importance of these attributes. In particular, we assessed whether food with an organic label could contain more fat or sugar and yet be judged to be of equivalent healthiness to food without this label. We hoped to estimate the magnitude of any such effect. Moreover, we explored whether these effects were obtained when including a widely used system for labeling food healthiness, the Traffic Light System. Although participants' healthiness choices were mainly driven by the reported fat and sugar content, the organic label also influenced healthiness judgments. Participants showed an organic halo effect leading them to consider the organic cookie as healthy as a conventional one despite containing more fat and sugar. Specifically, they considered the organic cookie as equivalent in healthiness to a conventional one, although containing 14% more of the daily reference intake for sugar and 30% more for fat. These effects did not change when including the Traffic Light System. This effect of the organic label could have implications for fat and sugar intake and consequent impacts on health outcomes.

Abstract
Recently, we have seen energy-efficient light-emitting diode (LED) light bulbs rapidly replace incandescent ones. However, results of new research are indicative of adverse health impacts of LED lighting, which is characterized by enriched blue light. Our study aims to reveal whether using color priming by attaching red/green traffic-light icons on light bulbs influences consumers’ preferences of light bulbs. We conducted a field study simulating the buying process, in which participants (N = 572) were presented with LED and carbon incandescent bulbs. We alternately displayed two pairs of bulbs: (1) in their original packaging and (2) in packages marked with traffic light icons (red = LED). Our results confirm that traffic light icons significantly (p < 0.01) increase the odds of choosing the healthier carbon bulb. The results highlight the benefits of attaching traffic light icons to light bulb packaging, helping consumers to make more health-conscientious purchasing decisions. Nowadays, this study’s contribution is more significant due to COVID-19 restrictions and stay-at-home policies, since people work or study remotely, which increases their exposure to household lighting. These results may incentivize policymakers to enforce adding traffic light icons to light bulb packaging, thus encouraging LED light bulb manufacturers to reduce the blue light component in order to improve the health aspect of their bulbs.

Consumers' Implicit and Explicit Recall, Understanding and Perceptions of Products with Nutrition-Related Messages: An Online Survey. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17218213.

Abstract
This study aimed to assess consumers' implicit and explicit recall, understanding and perceptions of products with a nutrition claim and a symbol depicting 'health,' and to determine whether these perceptions differed among Nutrition Facts table (NFt) users vs. nonusers. In an online survey, participants (n = 1997) were randomized to one of eight conditions in a 2 × 2 × 2 factorial design, consisting of a label with a claim (present/absent) a heart-shaped symbol depicting 'health' (present/absent) for a healthier or less healthy soup. Participants were shown a label for 10 s and asked whether they recalled seeing a claim. If participants answered yes, they were then asked to describe their response using open-ended questions. Participants also rated the product's perceived nutritional quality and purchase intentions using seven-point Likert scales. In the claim condition, most participants (75%) were able to recall the presence of a claim, while 12% incorrectly mentioned the presence of a claim when there was none. Claims likely attracted consumers' attention and increased perceived nutritional quality, although with limited influence among NFt users (23%). The symbol depicting 'health' did not enhance perceived nutritional quality or purchase intentions. Although most participants (77%) made their decisions implicitly using the front of labels, those who used the NFt had a better understanding of the nutritional quality of products.

Abstract
The rising prevalence of non-communicable diseases has brought attention to the importance of consuming a healthy diet. One strategy to improve diet quality is through front-of-pack (FOP) nutrition labels. Taking advantage of an online grocery store, we allowed consumers to choose the FOP labels they preferred, and combined this information with real-time feedback on the overall nutritional quality of the shopping basket. We hypothesized that these dynamic food labels with real-time feedback (DFLF) would improve nutritional quality of food purchases. This trial followed a two-arm (no-label control and DFLF) crossover design with 125 participants exposed to each condition once in random order via an online grocery store. A first difference regression model allowed for estimating the unbiased effect of the DFLF on diet quality, measured by the weighted average Nutri-Score (ranging 1 to 5) per serving (primary) and changes in select nutrients and calories. The mean weighted Nutri-Score was 0.4 (12.6%) higher in the DFLF arm (CI: [0.2, 0.6]) relative to the control. The DFLF also decreased the amount of sugar per serving by 0.9 g (CI: [−1.7, −0.0]) and total sugar per shop by 169.5 g (CI: [−284.5, −54.5]). The DFLF features significantly improved nutrition quality relative to no labelling, as measured by average Nutri-Score values. These results shed light on the considerable potential of the online shopping environment to improve diet quality through customization and real time feedback.

Abstract
PURPOSE OF REVIEW Guiding consumers toward more healthful food choices may help address the high prevalence of poor dietary quality and diet-related diseases. The use of front-of-package labels (FOPL) on food items is expanding to provide focused nutritional information or representations, often based upon nutrient profiling systems. RECENT FINDINGS FOPL provide a source of nutrition and health information that is readily understood by consumers, including those with limited literacy. There is evidence that FOPL can shift consumer behavior toward more nutritious and healthful choices. However, assessments of the effectiveness of FOPL have been restricted in scope and rely largely on simulation models rather than real-world environments. FOPL are a direct source of nutritional guidance at the point-of-purchase and provide an opportunity to convey critical information on ingredients that are associated with health promotion and/or increased risk of non-communicable diseases. However, limited evidence regarding the most effective forms of FOPL to achieve behavior change and challenges from the food industry impedes the establishment of standardized nutrient profiles and algorithms. Future opportunities for FOPL include the potential for integrating nutritional profiles with non-nutrient factors affecting health such as food processing and environmental sustainability.

Abstract
Growth in the consumer health and wellness industry has led to an increase of packaged foods marketed as health food (HF) products. In consequence, a ‘health halo’ around packaged HF has arisen that influences consumers at point-of-purchase. This study compared product claims (nutrient content claims (NCC), health claims and marketing ‘buzzwords’) displayed on packaged HF snack products sold in HF stores and HF aisles in supermarkets to equivalent products sold in regular aisles (RA) of supermarkets. Product Health Star Rating (HSR), nutrient profile and price were also compared. Data were collected for 2361 products from three supermarket chains, two HF chains and one independent HF store in Sydney, Australia. Mann-Whitney U tests compared the product claims, HSR, nutrient composition and unit ($) price. HF snacks displayed significantly more product claims per product compared to RA foods (HSR ≤ 2.5), median (IQR) 5.0(4.0) versus 1.0(2) and (HSR > 2.5) 4.0(4.0) versus 3.0(4), respectively (p < 0.001). A significantly different HSR was evident between HF and RA snack products, median 2.5(0) versus 2.0(1.5), respectively (p < 0.001). HF snacks cost significantly more than RA snack foods, irrespective of product HSR (p < 0.001). These findings support the recommendation for revised labelling regulations and increased education regarding consumers food label interpretation.

Abstract
Background Traffic-light labelling (TLL) is a promising front-of-pack system to help consumers make informed dietary choices. It has been shown that adopting TLL in Canada, through an optimistic scenario of avoiding, if possible, foods with red traffic lights, could effectively reduce Canadians’ intakes of energy, total fat, saturated fat, and sodium by 5%, 13%, 14% and 6%, respectively. However, the potential health impact of adopting TLL has not been determined in the North American context. Objective This study modelled the potential impact of adopting TLL on mortality from noncommunicable diseases (NCDs) in Canada, due to the previously predicted improved nutrient intakes. Methods Investigators used data from adults (n = 19,915) in the 2004 nationally representative Canadian Community Health Survey (CCHS)-Cycle 2.2. Nutrient amounts in foods consumed by CCHS respondents were profiled using the 2013 United Kingdom’s TLL criteria. Whenever possible, foods assigned at least one red light (non-compliant foods) were replaced with similar, but compliant, foods identified from a Canadian brand-specific food database. Respondents’ nutrient intakes were calculated under the original CCHS scenario and the counterfactual TLL scenario, and entered in the Preventable Risk Integrated ModEl (PRIME) to estimate the health impact of adopting TLL. The primary outcome was the number of deaths attributable to diet-related NCDs that could be averted or delayed based on the TLL scenario compared with the baseline scenario. Results PRIME estimated that 11,715 deaths (95% CI 10,500–12,865) per year due to diet-related NCDs, among which 72% are specifically related to cardiovascular diseases, could be prevented if Canadians avoided foods labelled with red traffic lights. The reduction in energy intakes would by itself save 10,490 deaths (9,312–11,592; 90%). Conclusions This study, although depicting an idealistic scenario, suggests that TLL (if used to avoid red lights when possible) could be an effective population-wide intervention to improve NCD outcomes in Canada.

Abstract
Front-of-pack labeling is a cost-effective strategy to decrease population consumption of sodium, sugar, saturated fat, total fat, and trans-fatty acids, considered critical nutrients for chronic disease. Our main objective was to explore the subjective understanding of labels that are currently used internationally among low- and middle-income Mexican consumers. We performed two phases of 10 focus groups with adolescents (13–15 y), young adults (21–23 y), mothers of children 3–12 y, fathers of children 3–12 y and older adults (55–70 y). Seven FOPL were evaluated: Guideline Daily Amounts, Multiple Traffic Light, Chilean Warning labels, Warning labels in Red, 5-Color Nutrition Label, Health Star Rating, and Healthy Choice label. Data was analyzed with a triangulation of researchers using a content analysis, based on three codes: 1) awareness and use of the Guideline Daily Amounts, 2) acceptability, and 3) subjective understanding of labels. Most participants were aware of the Guideline Daily Amounts, however they rarely used it because interpreting the information displayed on the label was too complicated. Health Star Rating, Warning labels, Multiple Traffic Light and the Healthy Choice logo labels were the most understandable, however the acceptability of the The Healthy Choice logo decreased as it did not provide information on specific ingredients. The Warning labels was the only label able to warn about critical nutrients that could represent a health risk. The Warning labels in red was more accepted compared to Warning labels in black. Results show that directive and semi-directive labels, such as Warning labels, Health Star Rating or Multiple Traffic Light, may be better at helping population of low- and middle income make healthier food choices, than non-directive FOPL such as the Guideline Daily Amounts implemented in México. The study results highlight the potential of Warning labels to support decreases in the consumption of critical ingredients in low- and middle-income Mexican consumers.

Abstract
Objectives. To determine which front-of-package label (out of 5 formats) is most effective at guiding consumers toward healthier food choices.Methods. Respondents from Argentina, Australia, Bulgaria, Canada, Denmark, France, Germany, Mexico, Singapore, Spain, the United Kingdom, and the United States took part in the Front-of-Pack International Comparative Experiment between April and July 2018. Respondents were shown foods of varying nutritional quality (with no label on package) and selected which they would be most likely to purchase. The same choice sets were then shown again with 1 of 5 randomly allocated labels on package (Health Star Rating (HSR), Multiple Traffic Lights (MTL), Nutri-Score, Reference Intakes, or Warning Label). We calculated an improvement score (from 11 100 valid responses) to identify the extent to which the labels produced healthier choices.Results. The most effective labels were the Nutri-Score and the MTL (mean improvement score = 0.09; 95% confidence interval [CI] = 0.07, 0.11), then the Warning Label (0.06; 95% CI = 0.04, 0.08), the HSR (0.05; 95% CI = 0.03, 0.07), and lastly the Reference Intakes (0.04; 95% CI = 0.02, 0.04).Conclusions. Well-designed, salient, and intuitive front-of-package labels can be effective on a global scale. Their impact is not bound to the country from which they originate.

Who Buys Products with Nutrition and Health Claims? A Purchase Simulation with Eye Tracking on the Influence of Consumers' Nutrition Knowledge and Health Motivation. Nutrients 2019; 11:nu11092199.

Abstract
Nutrition and health claims are seen as a way of promoting healthy aspects of food. However, the results of previous studies have been contradictory regarding the effect of these claims on purchase. This study aims to achieve a better understanding of how the consumer characteristics ‘nutrition knowledge’ and ‘health motivation’ influence the purchase of products with nutrition and health claims and what role gaze behavior plays. We included gaze behavior in our analysis, as visual attention on the claims is a precondition to its influence on the purchase decision. In a close-to-realistic shopping situation, consumers could choose from three-dimensional orange juice packages labeled with nutrition, health, and taste claims. In total, the sample consisted of 156 consumers. The data were analyzed with a structural equation model (SEM), linking the purchase decision for products with claims to gaze data recorded with a mobile eye tracker and consumer and product-related variables collected via the questionnaire. Results showed that the variables in the SEM explained 31% (8%) of the variance observed in the purchase of products with a nutrition (health) claim. The longer a consumer looked at a specific claim, the more likely the consumer would purchase the respective product. The lower the price and the higher the perceived healthiness and tastiness of the product further heightened its likelihood of being purchased. Interestingly, consumers with higher nutrition knowledge and/or higher health motivation looked longer at the nutrition and health claims; however, these consumer characteristics did not show an effect on the purchase decision. Implications for policy makers and marketers are given.

Abstract
Consumers’ perceptions of five front-of-pack nutrition label formats (health star rating (HSR), multiple traffic lights (MTL), Nutri-Score, reference intakes (RI) and warning label) were assessed across 12 countries (Argentina, Australia, Bulgaria, Canada, Denmark, France, Germany, Mexico, Singapore, Spain, the UK and the USA). Perceptions assessed included liking, trust, comprehensibility, salience and desire for the label to be mandatory. A sample of 12,015 respondents completed an online survey in which they rated one of the five (randomly allocated) front-of-pack labels (FoPLs) along the perception dimensions described above. Respondents viewing the MTL provided the most favourable ratings. Perceptions of the other FoPLs were mixed or neutral. No meaningful or consistent patterns were observed in the interactions between country and FoPL type, indicating that culture was not a strong predictor of general perceptions. The overall ranking of the FoPLs differed somewhat from previous research assessing their objective performance in terms of enhancing understanding of product healthiness, in which the Nutri-Score was the clear front-runner. Respondents showed a strong preference for mandatory labelling, regardless of label condition, which is consistent with past research showing that the application of labels across all products leads to healthier choices.

Abstract
OBJECTIVE To analyse the evolution of the soft drink industry's use of self-regulation as a response to obesity and examine the motivations driving its development and the strategies used to promote it to policy makers. DESIGN We used a data set of industry documents published by the Australian Beverages Council (ABC) between 1998 and 2016. We analysed how the ABC voiced its political motivations about self-regulation and what internal nutrition policies it developed prior to its public launch of self-regulation. We also analysed two promotional strategies: funding research and writing policy submissions. SETTING Australia. RESULTS Between 1998 and 2006, the ABC shifted from a defensive strategy that denied the role of its products in obesity to more conciliatory strategy that emphasised the role of the soft drink industry in solutions to obesity. The ABC deliberately timed the launch of its self-regulation to coincide with an international public health congress. Following its launch, the ABC funded research demonstrating the efficacy of self-regulation and wrote submissions to government nutrition policies arguing that further regulation was unnecessary. CONCLUSIONS The soft drink industry uses self-regulation to bolster its reputation and influence nutrition policy. Strategic timing plays a key role in the political influence of self-regulation.

Abstract
Front-of-pack labels (FoPLs) are efficient tools for helping consumers identify healthier food products. Although discussions on nutritional labelling are currently ongoing in Europe, few studies have compared the effectiveness of FoPLs in European countries, including the Netherlands. This study aimed to compare five FoPLs among Dutch participants (the Health Star Rating (HSR) system, Multiple Traffic Lights (MTL), Nutri-Score, Reference Intakes (RIs), and Warning symbols) in terms of perception and understanding of the labels and food choices. In 2019, 1032 Dutch consumers were recruited and asked to select one product from among a set of three foods with different nutritional profiles, and then rank the products within the sets according to their nutritional quality. These tasks were performed with no label and then with one of the five FoPLs on the package, depending on the randomization arm. Finally, participants were questioned on their perceptions regarding the label to which they were exposed. Regarding perceptions, all FoPLs were favorably perceived but with only marginal differences between FoPLs. While no significant difference across labels was observed for food choices, the Nutri-Score demonstrated the highest overall performance in helping consumers rank the products according to their nutritional quality.

Abstract
Labeling food packages with nutrition and health claims is a widely used practice. This study aims to contribute to the literature by examining the gaze and purchase behavior of consumers regarding food products with nutrition and health claims. A close-to-realistic purchase situation with three-dimensional food packages with nutrition, health, and taste claims was simulated while the participants' eye movements were measured using head-mounted eye tracking glasses. In the purchase situation, two food categories with differing perceived healthiness were offered, orange juice and milk chocolate. In total, 156 consumers participated in this study which was undertaken in Germany. The findings indicate that each claim was noticed by at least 85% of the participants and health claims were looked at longer than nutrition or taste claims. Furthermore, when compared to other participants, the longer a participant looked at a specific claim, the more likely the participant was to purchase the respective product. Even though the product category had no effect on the gaze duration on claims, it affected the purchase behavior. Nutrition claims were preferred for orange juice while taste claims were preferred for milk chocolate. Health claims were preferred for neither. Marketers can benefit from this study, as it shows the gaze duration on claims influenced the purchase likelihood. Another important finding is that there are great differences between product categories regarding the type of claim consumers prefer.

Abstract
Interpretive nutrition labels provide simplified nutrient-specific text and/or symbols on the front of pre-packaged foods, to encourage and enable consumers to make healthier choices. This type of labelling has been proposed as part of a comprehensive policy response to the global epidemic of non-communicable diseases. However, regulation of nutrition labelling falls under the remit of not just the health sector but also trade. Specific Trade Concerns have been raised at the World Trade Organization's Technical Barriers to Trade Committee regarding interpretive nutrition labelling initiatives in Thailand, Chile, Indonesia, Peru and Ecuador. This paper presents an analysis of the discussions of these concerns. Although nutrition labelling was identified as a legitimate policy objective, queries were raised regarding the justification of the specific labelling measures proposed, and the scientific evidence for effectiveness of such measures. Concerns were also raised regarding the consistency of the measures with international standards. Drawing on policy learning theory, we identified four lessons for public health policy makers, including: strategic framing of nutrition labelling policy objectives; pro-active policy engagement between trade and health to identify potential trade issues; identifying ways to minimize potential 'practical' trade concerns; and engagement with the Codex Alimentarius Commission to develop international guidance on interpretative labelling. This analysis indicates that while there is potential for trade sector concerns to stifle innovation in nutrition labelling policy, care in how interpretive nutrition labelling measures are crafted in light of trade commitments can minimize such a risk and help ensure that trade policy is coherent with nutrition action.

Abstract
Background As a public health intervention, front-of-pack labels (FoPLs) have the potential to reach large numbers of consumers and promote healthier food choices. Of the different FoPLs, those that summarize a product's overall nutritional profile tend to be most effective in guiding healthier choices. However, information is lacking as to whether FoPLs are as effective when nutrient or health claims also appear on-pack. Objective The aim of this study was to examine how the choice of foods of varying levels of healthfulness (less healthy, moderately healthy, and healthier) is affected by the appearance of various FoPLs (Daily Intake Guide, Multiple Traffic Lights, Health Star Rating) when shown in combination with different claim conditions (no claim, nutrient claim, general-level health claim, and higher-level health claim). Design Adults and children (n = 2069) completed a discrete-choice experiment online. Respondents were shown 8 choice sets, each containing 4 alternatives of the same food type (cookies, cornflakes, pizza, or yogurt) of varying levels of healthfulness and were asked which product they would likely purchase (or they could select none). Respondents were randomly assigned to view 1 of the 3 FoPLs across all choice sets. Claim type and healthfulness varied within choice sets in accordance with a D-efficient design. Results The probability of choosing a healthy product and avoiding an unhealthy product was greatest when only an FoPL (especially the Health Star Rating) appeared on-pack. The addition of a nutrient or health claim did not affect the likelihood of picking healthier products but did increase the likelihood of selecting less healthy foods across all FoPL conditions. Conclusions FoPLs are most effective in helping consumers make better food choices when nutrient and health claims are not present. Policies are required to control how nutrient and health claims are applied to less healthy foods.

Morrison H, Meloncelli N, Pelly FE. Nutritional quality and reformulation of a selection of children's packaged foods available in Australian supermarkets: Has the Health Star Rating had an impact? Nutr Diet 2018; 76:296-304. [PMID: 30426624 DOI: 10.1111/1747-0080.12486] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2018] [Revised: 08/01/2018] [Accepted: 09/11/2018] [Indexed: 01/29/2023]
Abstract
AIM To examine whether the nutritional quality of children's packaged food products available in Australian supermarkets improved between 2013 and 2016, and whether any change could be detected in product reformulation since the introduction of the Health Star Rating (HSR) labelling scheme. METHODS Packaged food products marketed towards children were purchased from three Australian supermarkets in July 2013 (for a previous study) and July 2016. Nutritional quality was assessed using the Food Standards Australian New Zealand Nutrient Profiling Scoring Criterion. Comparisons were made between the nutrient composition and formulation of products (a) available in 2013 and 2016; and (b) with and without HSR graphics. RESULTS Of the 252 children's packaged products analysed, 53.6% were classified as 'less healthy'. HSR-labelled products had a significantly higher proportion classified as 'healthy' than those without the HSR (χ2 = 26.5; P < 0.0001; 73.8% and 59.0%, respectively). Overall, 28.5% displayed the HSR; the majority (81.5%) having a rating of ≥3.0 stars. Cereal-based products had the greatest uptake of the scheme, with HSR-labelled products having significantly lower mean energy and saturated fat content (P < 0.01) and higher mean protein and fibre content (P < 0.001) than non-HSR products. Reformulation of products that were available in 2013 had occurred in 100% of HSR-labelled products in comparison to 61.3% of non-HSR labelled products. CONCLUSIONS Despite the introduction of the HSR, more than half of children's packaged foods sampled are 'less healthy'. However, early indications suggest that the HSR may stimulate healthier product reformulation.

Abstract
AbstractObjectiveTo examine consumers’ ability to correctly interpret front-of-package (FOP) ‘high in’ warnings in the presence of a voluntary claim for the same or a different nutrient.DesignA between-group experimental task assigned respondents to view food products labelled as ‘high in sodium’, with a ‘reduced sodium’ claim positioned next to the warning, away from the warning or absent. A second experiment assigned participants to view a food product labelled as ‘high in sugar’, with a ‘reduced fat’ claim positioned next to the warning, away from the warning or absent. For both tasks, respondents were asked to identify whether the products were high in the indicated nutrient.SettingOnline survey (2016).SubjectsCanadians aged 16–32 years (n 1000) were recruited in person from five major cities in Canada.ResultsRespondents were less likely to correctly identify a product as ‘high in sodium’ when packages also featured a voluntary ‘reduced sodium’ claim, with a stronger effect when the claim was positioned away from the FOP symbol (P<0·001). The number of correct responses was similar across conditions when the nutrient claim was for a different nutrient than the one featured in the FOP ‘high in’ warning.ConclusionsThe findings demonstrate that the presence of a voluntary nutrient claim can undermine the efficacy of mandated FOP labels for the same nutrient. Countries considering nutrient-specific FOP warnings, including Canada, should consider regulations that would prohibit claims for nutrients that exceed the threshold for nutrient-specific FOP warnings.

Abstract
Front-of-Package labels (FoPLs) are efficient tools for increasing consumers' awareness of foods' nutritional quality and encouraging healthier choices. A label's design is likely to influence its effectiveness; however, few studies have compared the ability of different FoPLs to facilitate a consumer understanding of foods' nutritional quality, especially across sociocultural contexts. This study aimed to assess consumers' ability to understand five FoPLs [Health Star Rating system (HSR), Multiple Traffic Lights (MTL), Nutri-Score, Reference Intakes (RIs), and Warning symbol] in 12 different countries. In 2018, approximately 1000 participants per country were recruited and asked to rank three sets of label-free products (one set of three pizzas, one set of three cakes, and one set of three breakfast cereals) according to their nutritional quality, via an online survey. Participants were subsequently randomised to one of five FoPL conditions and were again asked to rank the same sets of products, this time with a FoPL displayed on pack. Changes in a participants' ability to correctly rank products across the two tasks were assessed by FoPL using ordinal logistic regression. In all 12 countries and for all three food categories, the Nutri-Score performed best, followed by the MTL, HSR, Warning symbol, and RIs.

Abstract
The U.S. Food and Drug Administration (FDA) recently made changes to the nutrition facts label so that calories will be emphasized over all other nutrient information (U.S. Food and Drug Administration (FDA), 2016a, August 3). In light of calories' increased visibility, strategic health communicators need to understand both how individuals perceive calorie information and how calories influence consumption decisions. Therefore, a qualitative study was conducted to analyze the metaphors that structure consumers' thoughts about calorie information and food choices. In-depth interviews were conducted with 34 women from diverse racial/ethnic and socioeconomic backgrounds. Through the interviews and subsequent thematic analysis, metaphors were gathered that explained perceptions of different kinds of calories and how calories function in the diet. Five conceptual metaphors were uncovered. The metaphors individuals used varied based on their eating paradigms, and the metaphors were related to different approaches to consumption decisions. The implications of using these different calorie metaphors for translational communication interventions are further discussed.

Abstract
Front-of-pack (FoP) nutrition labels are a widely deployed tool in public good marketing. This article reports on a field experimental test of the impact of one of these systems, the Australasian Health Star Rating system (HSR), on consumer choice in the breakfast cereals category in New Zealand. This study forms part of a time-series replication stream of research on this topic. The research applied a 2 × 2 factorial design with multiple replications to retail food consumers exiting from supermarkets in New Zealand. The first part of the time series, undertaken shortly after the HSR’s initiation in 2014, indicated that the HSR was ineffective. Between 2014 and 2016, commercial brands in the category within New Zealand massively promoted the HSR as a basis for consumer choice. The research presented in this article forms part of the second part of the series, undertaken in 2016, using an identical experimental methodology to the 2014 study. The results indicate that the HSR may be beginning to influence consumer choice as it was predicted to, but the impact of the system is still small, and statistically sub-significant, relative to other consumer decision inputs presented on the package.

Are Front-of-Package Warning Labels More Effective at Communicating Nutrition Information than Traffic-Light Labels? A Randomized Controlled Experiment in a Brazilian Sample. Nutrients 2018; 10:E688.

Abstract
BACKGROUND Brazil is currently debating the implementation of front-of-package labels. This study tested if Warning labels (WLs) improved consumer understanding, perceptions, and purchase intentions compared to Traffic-Light labels (TLLs) in 1607 Brazilian adults. METHODS In this online, randomized controlled experiment participants saw images of 10 products and answered questions twice-once in a no-label, control condition and then again in a randomly assigned label condition. The relative differences in responses between WLs and TLLs between control and label conditions were estimated using one-way ANOVAs or Chi-square tests. RESULTS Presenting WLs on products compared to TLLs helped participants: (i) improve their understanding of excess nutrient content (27.0% versus 8.2%, p < 0.001); (ii) improve their ability to identify the healthier product (24.6% versus 3.3%, p < 0.001); (iii) decrease perceptions of product healthfulness; and (iv) correctly identify healthier products (14.0% versus 6.9%, p < 0.001), relative to the control condition. With WLs, there was also an increase in the percentage of people: (v) expressing an intention to purchase the relatively healthier option (16.1% versus 9.8%, p < 0.001); and (vi) choosing not to buy either product (13.0% versus 2.9%, p < 0.001), relative to the control condition. The participants in the WL condition had significantly more favorable opinions of the labels compared to those in the TLL group. CONCLUSIONS WLs would be more effective at improving consumer food choices.

Abstract
The research on nutrition, health, and risk reduction claims (NHR claims) shows a lack of consensus as to whether these claims have a positive or negative effect on consumer's preferences and purchase behavior. This issue has been highlighted by many authors. Therefore, a comprehensive literature review was performed to find reasons for contradictory results. First, a theoretical framework was developed which divided the determinants of the effects of NHR claims on consumers' preferences and purchase behavior into consumer and product-specific characteristics. Additionally, a categorization for the different NHR claim types was constructed to make the studies comparable. Afterwards, the scientific literature from the 1980s until May 2017 was scanned and 66 articles were found to be relevant. Consumer-specific characteristics such as nutrition knowledge, health motivation, familiarity, and socio-demographic characteristics were found to influence the NHR claim effect. Important product-specific characteristics were the perceived healthiness of the food product, the interaction between the product and the nutrient in the NHR claim, and the interaction between the claimed benefit and the NHR claim type. The consumer's nutrition knowledge and the product's perceived healthiness were deemed to be the most promising determinants for further investigation.

Abstract
A higher sugar intake in infancy might result in a predisposition to a higher sugar intake in later childhood. In Taiwan, many commercial infant and toddler foods with nutrition claims have high sugar content. This study explored the influence of mothers’ knowledge and attitudes on their purchase intention for infant food with nutrition claims. This study was a cross-sectional survey. An online survey was distributed to 940 mothers who had a child aged between 4 months and 3 years; 40% of mothers tend to misunderstand that “no added sugar” (NAS) indicates no sugar or less sugar content and, thus, that NAS infant cereal is healthy. Approximately 50–70% of mothers believe that NAS infant cereal is more natural, healthier, and contains less sugar. Attitude toward the NAS claim was found to be a mediating variable between sugar-related knowledge and purchase intention. The lower the level of sugar-related knowledge was, the more positive the attitude toward NAS infant cereal and the higher the purchase intention for NAS infant cereal were. In the future, regulation of no added sugar is needed to avoid the misleading information and mothers’ sugar-related knowledge need to be improved through nutrition education.

Abstract
OBJECTIVE The present research aimed to investigate the impact of the physical activity calorie equivalent (PACE) front-of-pack label on consumption, prospective consumption and liking of familiar and unfamiliar discretionary snack foods. DESIGN In a within-subject randomised design, participants tasted and rated liking (9-point hedonic scale) and prospective consumption (9-point category scale) of four different snack foods with four different labels (i.e. blank, fake, PACE, PACE doubled) and four control snack foods. The twenty snack foods were presented during two 45 min sessions (i.e. ten snack foods per session) which were separated by one week. The amount participants sampled of each snack food was measured. SETTING The study was conducted in the Centre for Advanced Sensory Sciences laboratory at Deakin University, Australia. SUBJECTS The participants were 153 university students (126 females, twenty-seven males, mean age 24·3 (sd 4·9) years) currently enrolled in an undergraduate nutrition degree at Deakin University. RESULTS When the PACE label was present on familiar snack foods, participants sampled 9·9 % (22·8 (sem 1·4) v. 25·3 (sem 1·5) g, P=0·03) less than when such label was not present. This was in line with a decreased prospective snack food consumption of 9·1 % (3·0 (sem 0·2) v. 3·3 (sem 0·2) servings, P=0·03). Such pattern was not seen in unfamiliar snacks. CONCLUSIONS The PACE label appears to be a promising way to decrease familiar discretionary snack food consumption in young, health-minded participants.

Abstract
BACKGROUND This study examined how front-of-pack labels and product healthfulness affect choice and willingness to pay across a range of foods. It was hypothesized that: (i) product choice and (ii) willingness to pay would be more aligned with product healthfulness when healthfulness was expressed through the Health Star Rating, followed by the Multiple Traffic Light, then the Daily Intake Guide, and (iii) the Nutrition Facts Panel would be viewed infrequently. METHODS Adults and children aged 10+ years (n = 2069) completed an online discrete choice task involving mock food packages. A 4 food type (cookies, corn flakes, pizza, yoghurt) × 2 front-of-pack label presence (present, absent) × 3 front-of-pack label type (Daily Intake Guide, Multiple Traffic Light, Health Star Rating) × 3 price (cheap, moderate, expensive) × 3 healthfulness (less healthy, moderately healthy, healthier) design was used. A 30 s time limit was imposed for each choice. RESULTS Of the three front-of-pack labels tested, the Health Star Rating produced the largest differences in choices, with 40% (95% CIs: 38%-42%) of respondents selecting the healthier variant, 33% selecting the moderately healthy variant (95% CIs: 31%-35%), and 23% (95% CIs: 21%-24%) selecting the less healthy variant of the four products included in the study. The Multiple Traffic Light led to significant differences in choices between healthier (35%, 95% CIs: 33%-37%) and less healthy products (29%, 95% CIs: 27%-31%), but not moderately healthy products (32%, 95% CIs: 30%-34%). No significant differences in choices were observed by product healthfulness when the Daily Intake Guide was present. Only the Health Star Rating resulted in a significantly greater willingness to pay for healthier versus less healthy products. The Nutrition Facts Panel was viewed for only 7% of all mock packages. CONCLUSIONS Front-of-pack labels that are more interpretive, such as the Health Star Rating, can be more effective at directing consumers towards healthier choices than reductive front-of-pack labels such as the Daily Intake Guide. The study results provide policy makers with clear guidance on the types of front-of-pack labels that are most likely to achieve positive health outcomes at a population level.

Effects of Different Types of Front-of-Pack Labelling Information on the Healthiness of Food Purchases-A Randomised Controlled Trial. Nutrients 2017; 9:nu9121284. [PMID: 29186803 PMCID: PMC5748735 DOI: 10.3390/nu9121284] [Citation(s) in RCA: 64] [Impact Index Per Article: 9.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2017] [Revised: 11/10/2017] [Accepted: 11/19/2017] [Indexed: 11/16/2022] Open
Abstract
Background: Front-of-pack nutrition labelling may support healthier packaged food purchases. Australia has adopted a novel Health Star Rating (HSR) system, but the legitimacy of this choice is unknown. Objective: To define the effects of different formats of front-of-pack labelling on the healthiness of food purchases and consumer perceptions. Design: Individuals were assigned at random to access one of four different formats of nutrition labelling—HSR, multiple traffic light labels (MTL), daily intake guides (DIG), recommendations/warnings (WARN)—or control (the nutrition information panel, NIP). Participants accessed nutrition information by using a smartphone application to scan the bar-codes of packaged foods, while shopping. The primary outcome was healthiness defined by the mean transformed nutrient profile score of packaged foods that were purchased over four weeks. Results: The 1578 participants, mean age 38 years, 84% female recorded purchases of 148,727 evaluable food items. The mean healthiness of the purchases in the HSR group was non-inferior to MTL, DIG, or WARN (all p < 0.001 at 2% non-inferiority margin). When compared to the NIP control, there was no difference in the mean healthiness of purchases for HSR, MTL, or DIG (all p > 0.07), but WARN resulted in healthier packaged food purchases (mean difference 0.87; 95% confidence interval 0.03 to 1.72; p = 0.04). HSR was perceived by participants as more useful than DIG, and easier to understand than MTL or DIG (all p < 0.05). Participants also reported the HSR to be easier to understand, and the HSR and MTL to be more useful, than NIP (all p < 0.03). Conclusions: These real-world data align with experimental findings and provide support for the policy choice of HSR. Recommendation/warning labels warrant further exploration, as they may be a stronger driver of healthy food purchases.

Nutr Rev 2017; 75:260-273. [PMID: 28371913 DOI: 10.1093/nutrit/nuw070] [Citation(s) in RCA: 44] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2016] [Accepted: 10/21/2016] [Indexed: 01/04/2023] Open
Abstract
Context The presence of health claims on food packaging can positively bias consumers' evaluations of foods. This review examined whether cognitive biases endure when other sources of nutrition information [the nutrition facts panel (NFP) and front-of-pack labels] appear on-pack with health claims. The following databases were searched: Web of Science, Ovid, Google Scholar, ScienceDirect, Scopus, ProQuest, and Wiley Online Library. The search terms ("health claim*" OR "nutri* claim") AND ("food label*" OR "front of pack") were used to identify studies. Twenty-four studies that examined health claims and front-of-pack labels or the NFP were included. The NFP can reduce bias, but only if consumers view it and interpret it correctly, which often does not occur. Front-of-pack labels show greater promise in reducing bias created by health claims. These findings are relevant to policymakers who are considering the effectiveness of mandating an NFP and/or a front-of-pack label alongside health claims.

Abstract
AbstractObjectiveWarnings are a new directive front-of-pack (FOP) nutrition labelling scheme that highlights products with high content of key nutrients. The design of warnings influences their ability to catch consumers’ attention and to clearly communicate their intended meaning, which are key determinants of their effectiveness. The aim of the present work was to evaluate the influence of design features of warnings as a FOP nutrition labelling scheme on perceived healthfulness and attentional capture.DesignFive studies with a total of 496 people were carried out. In the first study, the association of colour and perceived healthfulness was evaluated in an online survey in which participants had to rate their perceived healthfulness of eight colours. In the second study, the influence of colour, shape and textual information on perceived healthfulness was evaluated using choice-conjoint analysis. The third study focused on implicit associations between two design features (shape and colour) on perceived healthfulness. The fourth and fifth studies used visual search to evaluate the influence of colour, size and position of the warnings on attentional capture.ResultsPerceived healthfulness was significantly influenced by shape, colour and textual information. Colour was the variable with the largest contribution to perceived healthfulness. Colour, size and position of the warnings on the labels affected attentional capture.ConclusionsResults from the experiments provide recommendations for the design of warnings to identify products with unfavourable nutrient profile.
