Abstract
Nutrition labeling on the front of food packages can support more healthful purchase decisions and encourage favorable reformulation. This systematic literature review applied Cochrane methods to synthesize and appraise the evidence on the effectiveness of front-of-pack labeling (FOPL) on diet-related outcomes and food reformulation to inform policy recommendations. The search was conducted on 11 academic and gray literature databases, from inception to July 2022. Evidence was synthesized using GRADE (Grading of Recommendations, Assessment, Development, and Evaluation), vote counting, and meta-analyses, where appropriate. Overall, 221 articles were included in the review. The randomized controlled trial evidence suggested that, compared with when no FOPL was present, FOPL likely improved consumer understanding of the nutritional quality/content of foods (moderate certainty of evidence), and the healthfulness of food choices (moderate certainty) and purchases (moderate certainty). Interpretive FOPL had a greater effect on these outcomes compared with noninterpretive systems (moderate certainty). There was inconsistency in the best-performing interpretive FOPL system.

Abstract
Nutrition labeling supports healthier diets by aiding purchase decisions and stimulating reformulation. This systematic literature review applied Cochrane methods to synthesize and appraise evidence on the effectiveness of nutrient declarations and nutrition and health claims on diet-related outcomes. The search spanned 11 academic databases, from inception to July 2022. Evidence was synthesized using GRADE (Grading of Recommendations, Assessment, Development, and Evaluation) and vote counting. Data were available from 170 studies. Randomized controlled trials (RCTs) suggest that nutrient declarations likely improved consumer understanding of the nutritional quality/content of foods (moderate certainty) and may have improved the healthfulness of choices (low certainty) versus no label. RCT evidence also suggests that claims likely increased consumer perceptions of food healthfulness and increased choice and purchases of labeled foods (both moderate certainty), irrespective of nutritional quality. To improve label understanding and avoid misinterpretation, nutrient declarations may incorporate interpretive elements and claims can apply disqualifying conditions for their usage, on the basis of overall nutritional quality.

Abstract
OBJECTIVE To evaluate the trends in the healthiness of packaged food purchases of Australian consumers before and after the introduction of the Health Star Rating (HSR) nutrition labels. DESIGN Panel data analysis and difference-in-differences analysis. SETTING The Australian Government endorsed HSR nutrition labels for voluntary implementation on packaged foods in June 2014. We analyse the packaged food purchases of households across all major supermarkets before (January 2014 to June 2014) and after (June 2014-Dec 2018) the introduction of HSR. PARTICIPANTS 6284 members of a panel of households across Australia reporting their grocery purchases to a market research company (Nielsen Homescan panel). RESULTS The healthiness of household food purchases exhibited a U-shaped trend - decreasing from 2014 to 2017, and then increasing from 2018, corresponding to the time when a higher proportion of products were HSR-labelled. Households that purchased a higher proportion of HSR-labelled products had healthier household purchases overall. Further, the healthiness of households' category-specific food purchases was positively associated with the proportion of HSR-labelled products in categories where HSR was adopted, relative to control categories where HSR was not adopted. CONCLUSIONS In Australia, once a substantial number of packaged food products adopted the voluntary HSR summary indicator, we observed an increasing trend in the healthiness of household food purchases. Widespread adoption of a nutrition summary indicator, such as HSR, on packaged food is likely to be beneficial for population health.

Abstract
This narrative review revises the scientific evidence of recent years on healthy eating in children and adolescents, making sense of promising avenues of action, from a food system perspective. A conceptual framework is provided to better understand how eating habits of children and adolescents are shaped to identify key multisectoral approaches that should be implemented to promote healthier diets. The following influencing factors are discussed: individual factors (physiological and psychological factors, food preferences and food literacy competencies), factors within the personal and socio-cultural food environments, external food environments, and the supply chain. In each section, the main barriers to healthy eating are briefly discussed focussing on how to overcome them. Finally, a discussion with recommendations of actions is provided, anchored in scientific knowledge, and transferable to the general public, industry, and policymakers. We highlight that multidisciplinary approaches are not enough, a systems approach, with a truly holistic view, is needed. Apart from introducing systemic changes, a variety of interventions can be implemented at different levels to foster healthier diets in children through fostering healthier and more sustainable food environments, facilitating pleasurable sensory experiences, increasing their food literacy, and enhancing their agency by empowering them to make better food related decisions. Acknowledging children as unique individuals is required, through interpersonal interactions, as well as their role in their environments. Actions should aim to enable children and adolescents as active participants within sustainable food systems, to support healthier dietary behaviours that can be sustained throughout life, impacting health at a societal level.

A Randomized Controlled Study to Test Front-of-Pack (FOP) Nutrition Labels in the Kingdom of Saudi Arabia. Nutrients 2023; 15:2904. [PMID: 37447230 DOI: 10.3390/nu15132904] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2023] [Revised: 06/19/2023] [Accepted: 06/21/2023] [Indexed: 07/15/2023] Open
Abstract
One common strategy for governments to tackle the non-communicable disease (NCD) epidemic is front-of-package (FOP) nutrition labeling. The Kingdom of Saudi Arabia (KSA) is considering implementing a new FOP label that is based on either France's Nutri-Score (NS), which labels all foods (A = healthiest to E = least healthy) based on overall nutritional quality, or the Chilean warning label (WL) approach, which identifies foods to avoid based on select nutritional characteristics. Using a fully functional online grocery store, this study aimed to test these two promising FOP strategies by randomizing 656 KSA adults into one of the three versions of the store to complete a hypothetical grocery shop: no-label (control), NS, and WL. The NS was modified with a sugar percentage tag given that reducing sugar consumption is one of KSA's public health goals. We found that both modified NS labels and Chilean warning labels positively influenced food and beverage choices among KSA participants, but there were differential effects across the two labels. Relative to the control, NS improved the overall diet quality of the shopping baskets, measured by the weighted (by the number of servings) average NS point (ranging from 0, least healthy, to 55, healthiest), by 2.5 points [95% CI: 1.7, 3.4; p < 0.001], whereas results for WL were not statistically significant (0.6 points [95% CI: -0.2,1.5]). With respect to each nutritional attribute, we found that NS reduced sugar intake per serving, whereas WL was effective at decreasing energy and saturated fat intake per serving from food and beverages purchased. Our results suggest that the NS approach that identifies the healthiness of all foods using a holistic approach appears preferable if the purpose of the label is to improve overall diet quality as opposed to addressing select nutrients to avoid.

Effect of a new graphically modified Nutri-Score on the objective understanding of foods' nutrient profile and ultraprocessing: a randomised controlled trial. BMJ Nutr Prev Health 2023; 6:108-118. [PMID: 37484539 PMCID: PMC10359533 DOI: 10.1136/bmjnph-2022-000599] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2022] [Accepted: 05/18/2023] [Indexed: 07/25/2023] Open
Abstract
Introduction When considering health-related impacts of foods, nutrient profile and (ultra)processing are two complementary dimensions. The Nutri-Score informs on the nutrient profile dimension. Recently, mounting evidence linked ultraprocessed food consumption to various adverse health outcomes, independently of their nutrient profile. To inform consumers about each of these health-related dimensions of food, we tested, in a randomised controlled trial, if a graphically modified version 'Nutri-Score V.2.0', including a black 'ultraprocessed' banner, would improve the capacity of consumers to rank products according to their nutrient profile and to detect those ultra-processed, compared with a no-label situation. Methods 21 159 participants included in the NutriNet-Santé web-cohort were randomly assigned to a control arm (no front-of-pack label) or an experimental arm (Nutri-Score 2.0) and were presented an online questionnaire with three sets of food products (cookies, breakfast cereals and ready-to-eat meals) to rank according to nutrient profile and to identify ultraprocessed foods. The primary outcome was objective understanding of nutrient profile and ultraprocessing, represented by a score of correct answers. Secondary outcomes were purchasing intentions and the healthiest-perceived product. Multinomial logistic regressions were performed. Results The Nutri-Score V.2.0 increased the objective understanding of both the nutrient profile dimension (OR highest vs lowest score category=29.0 (23.4-35.9), p<0.001) and the ultraprocessing dimension (OR=174.3 (151.4-200.5), p<0.001). Trends were similar for cookies, breakfast cereals and ready-to-eat meals. The Nutri-Score V.2.0 had a positive effect on purchasing intentions and on the products perceived as the healthiest. Conclusion This randomised controlled trial demonstrates the interest of a front-of-pack label combining the Nutri-Score (informing on the nutrient profile dimension) with an additional graphic mention, indicating when the food is ultraprocessed, compared with a no-label situation. Our results show that a combined label enabled participants to independently understand these two complementary dimensions of foods. Trial registration number NCT05610930.

Abstract
Objectives To evaluate the nutritional quality of products carrying health or nutritional claims to protect consumers from being misled and to ensure that they are provided with accurate information about food products that are associated with health or nutritional claims. Methods This was a cross-sectional survey of 1153 foods that were randomly sampled from 14 stores in Riyadh, KSA. The data were collected from nutritional facts presented on food labels and evaluated by comparing the mean level of nutrients between products that featured claims and those that did not use the UK nutrient profile model (UKNPM). Results Overall, 29% of products carried either health or nutritional claims. Only 19.2% of foods that carried health claims met Saudi Food and Drug Authority (SFDA) requirements, while 28.9% of all products that carried nutritional claims met SFDA criteria; however, the analysis indicated that products that carried health or nutritional claims were significantly lower in sugar (9.67 g/100 g), fat (9.2 g/100 g), saturated fat (3.2 g/100 g), and sodium (371.36 mg/100 g). According to the UKNPM, 46.9% of the products carrying claims were less healthy than those not carrying claims, and statistically significant differences were observed by product origin and category (p < 0.005 and p < 0.000, respectively). Conclusion The current representation of unregulated claims on food products may mislead the consumer. There is an urgent need for government legislation that limits their use except under certain conditions for the optimal protection of the population's health.

Abstract
OBJECTIVE To assess the effects of three different front-of-package labelling (FOPL) schemes on objective understanding and intention to purchase of products, in Jamaica. SETTING Supermarkets in Jamaica. PARTICIPANTS Adult supermarket shoppers in Jamaica (n=1206) aged 18 years old or older were included in the study, except for those visually impaired, or unable to give informed consent. DESIGN Multiarm parallel-group randomised trial. INTERVENTIONS Participants were randomly allocated to one of the three intervention groups or the control group. They were exposed to two-dimensional images of 12 mock-up products presented in random and balanced order. Participants assigned to the intervention groups were exposed to one FOPL scheme: black octagonal warning labels (OWL), magnifying glass high-in single icon (MGG) or traffic-light labelling (TFL). The control group was exposed to the nutrition facts up front. OUTCOME MEASURES OR for correctly understanding nutritional information (correctly selecting the least harmful option, correctly identifying sugars, sodium and/or saturated fats found to be in excess) and choosing to purchase the least harmful option (purchase intention), more often. RESULTS Compared with the control group, the odds for correctly selecting the least harmful option more often were 107% higher in the OWL group (OR 2.07, 95% CI 1.54 to 2.78; p<0.001), whereas the MGG (1.18, 95% CI 0.89 to 1.57; p=0.24) and the TFL (1.13, 95% CI 0.85 to 1.51; p=0.39) were inefficacious in improving such odds. OWL also resulted in the highest odds for correctly identifying a product with excessive amounts of sugars, sodium and/or saturated fats and for deciding to purchase the least harmful option or none of the options. CONCLUSIONS Octagonal warning labels performed best at improving the ability of adult shoppers in Jamaica to understand the nutrition information and at encouraging them to purchase the least harmful option more often.

Exploratory analysis of a cluster randomized controlled trial of a multi-strategy intervention delivered via online canteens on improving the nutritional quality of primary school students' pre-ordered foods & drinks at recess. Appetite 2023; 185:106528. [PMID: 36907518 DOI: 10.1016/j.appet.2023.106528] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2022] [Revised: 01/12/2023] [Accepted: 03/05/2023] [Indexed: 03/12/2023]
Abstract
School canteens are a recommended setting to deliver public health nutrition strategies given their wide reach, and frequent use by children. Online canteens, where users (i.e. students or their carers) pre-order and pay for food and drinks online, represent attractive systems to deliver strategies that encourage healthier food choices. There have been few studies exploring the efficacy of public health nutrition interventions in online food ordering environments. Therefore, this study aims to assess the efficacy of a multi-strategy intervention implemented in an online school canteen ordering system in reducing the energy, saturated fat, sugar, and sodium content of students' online recess orders (i.e. foods ordered during the mid-morning or afternoon snack period). This was an exploratory analysis of recess purchases for a cluster randomized controlled trial that initially sought to examine the efficacy of the intervention on lunch orders. A total of 314 students from 5 schools received the multi-strategy intervention (involving menu labelling, placement, prompting and availability) that was integrated into the online ordering system, and 171 students from 3 schools received the control (usual online ordering). Analysis of main outcomes found that the mean energy (difference: -269.3 kJ; P = 0.006), saturated fat (difference: -1.1 g; P = 0.011) and sodium (difference: -128.6 mg; P = 0.014) content per student recess order was significantly lower in the intervention group than the control group at 2-month follow-up. Findings suggest that embedding strategies to encourage healthier choices within online canteen ordering systems can improve the nutrient composition of student recess purchases. These results add to the current evidence base suggesting that interventions delivered via online food ordering systems represent an effective strategy for improving child public health nutrition in schools.

A randomized trial to evaluate the impact of Singapore's forthcoming Nutri-grade front-of-pack beverage label on food and beverage purchases. Int J Behav Nutr Phys Act 2023; 20:18. [PMID: 36793058 PMCID: PMC9930047 DOI: 10.1186/s12966-023-01422-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2022] [Accepted: 02/06/2023] [Indexed: 02/17/2023] Open
Abstract
BACKGROUND The epidemic of non-communicable diseases (NCDs) is a growing concern worldwide and Singapore is no exception to this global trend. As part of measures to address this concern, the Singapore government will implement a mandatory color-coded front-of-package (FOP) nutrition label for beverages, called Nutri-Grade (NG), which will complement the existing FOP label, Healthier Choice Symbol (HCS) logos, currently displayed on select food and beverage items. NG grades beverages on a four-point scale, A (healthiest) to D (least healthy), in terms of sugar and saturated fat levels. This study aimed to evaluate the effectiveness of the NG label on nutritional quality of pre-packaged beverages using a fully functional online grocery store. METHODS We conducted a 2-arm crossover trial involving actual purchases with 138 participants randomly exposed to: 1) Control with HCS logos displayed on qualifying items; 2) Similar to Control except that all beverages displayed the NG label. The effects of the NG label were estimated using a linear mixed-effects model that addresses correlations between repeated measures and accommodates missing data. RESULTS We found that the NG label encouraged consumers to choose beverages with higher ratings. This led to a reduction in sugar from beverages purchased by 1.51 g [95% CI: - 2.68, - 0.34] per serving but was not effective at reducing saturated fat purchased (- 0.009 g [95% CI: - 0.22, 0.20]) per serving or improvements in overall diet quality, measured by the weighted (by the number of servings) average Nutri-Score value ranging from 1 to 5 (- 0.024 [95% CI: - 0.13, 0.08]). CONCLUSIONS Results suggest that the Nutri-Grade label is likely to reduce sugar purchased from beverages. However, to improve overall diet quality in Singapore, additional measures will be needed. TRIAL REGISTRATION This trial was registered on ClinicalTrials.gov under the identifier: NCT05018026 on 24th August 2021.

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.

Appetite 2022; 176:106105. [PMID: 35700838 DOI: 10.1016/j.appet.2022.106105] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2022] [Revised: 05/24/2022] [Accepted: 05/30/2022] [Indexed: 11/24/2022]
Abstract
Nutrition and health claims (NHCs) can help individuals make better food choices. While NHCs have been found to influence consumer perceptions and consumption, there has been less focus on how claims influence the nutritional composition of servings. There has also been little attention paid to longer term or compensatory effects of claims on subsequent food selection. This manuscript details two studies considering these matters. Study 1 (n = 60) was a within-subjects experiment to measure the impact of NHCs on food selection and nutritional composition at single meal servings. Participants served from three fake food buffet meal stations (breakfast, hot meal, snacks) with NHCs present or absent. Study 2 (n = 55) was a within-subjects experiment to examine the impact of NHCs on food selection and nutritional composition at a subsequent meal. Participants served from a fake food buffet breakfast with or without NHCs followed by a lunch without NHCs. In study 1, while results varied for different meals, the presence of claims was found to significantly reduce the amount of energy, fat, saturated fat, sugar, carbohydrates, and sodium, and increase the amount of protein in meals that were served. Results for fibre were mixed. In addition, NHCs increased the quantity of food served in the snacks condition. There was no evidence of claims at breakfast impacting the nutritional composition of subsequent lunch servings in study 2. Despite claims potentially increasing serving quantities, the nutritional composition of chosen servings was more encouraging and claims may help individuals to meet recommended nutritional daily guidelines. These findings have wider implications in terms of government policy, food reformulation, and the continuing debate around the use of nutrient profiling regulations for products carrying claims.

"It's All Just Marketing", a Qualitative Analysis of Consumer Perceptions and Understandings of Nutrition Content and Health Claims in New Zealand. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19063510. [PMID: 35329195 PMCID: PMC8949035 DOI: 10.3390/ijerph19063510] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/11/2022] [Revised: 03/10/2022] [Accepted: 03/14/2022] [Indexed: 12/10/2022]
Abstract
Nutrition content and health claims are widely used globally on both food labels and in food advertising. This study explored how New Zealand consumers understand, perceive, and use nutrition content and health claims on food labels. A qualitative approach was used with semi-structured in-depth online interviews and in-person focus groups including 49 participants, aged ≥25 years responsible for household food shopping. Transcripts were analysed using reflexive thematic analysis using inductive coding, with development of five themes—(1) aware of claims but did not use, (2) mistrust and scepticism, (3) confusion and misinterpretation, (4) using claims to guide food choice, and (5) not all claims are equal. For theme 1, price and habit were found to be the most influential in driving food choice. Underlying theme 2 was the perception by most of nutrition and health claims as marketing. Scepticism was exacerbated when nutrient claims were displayed on inherently unhealthy products. However participants with specific dietary requirements did find claims helpful. Restricting nutrient claims to foods meeting a healthy nutrient profile aligned to the existing Health Star Rating system, education about regulation and supporting claims with more contextual information may increase trust, the perceived value of claims and therefore their utility.

Impact of color-coded and warning nutrition labelling schemes: A systematic review and network meta-analysis. PLoS Med 2021; 18:e1003765. [PMID: 34610024 PMCID: PMC8491916 DOI: 10.1371/journal.pmed.1003765] [Citation(s) in RCA: 73] [Impact Index Per Article: 24.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/09/2020] [Accepted: 08/11/2021] [Indexed: 01/22/2023] Open
Abstract
BACKGROUND Suboptimal diets are a leading risk factor for death and disability. Nutrition labelling is a potential method to encourage consumers to improve dietary behaviour. This systematic review and network meta-analysis (NMA) summarises evidence on the impact of colour-coded interpretive labels and warning labels on changing consumers' purchasing behaviour. METHODS AND FINDINGS We conducted a literature review of peer-reviewed articles published between 1 January 1990 and 24 May 2021 in PubMed, Embase via Ovid, Cochrane Central Register of Controlled Trials, and SCOPUS. Randomised controlled trials (RCTs) and quasi-experimental studies were included for the primary outcomes (measures of changes in consumers' purchasing and consuming behaviour). A frequentist NMA method was applied to pool the results. A total of 156 studies (including 101 RCTs and 55 non-RCTs) nested in 138 articles were incorporated into the systematic review, of which 134 studies in 120 articles were eligible for meta-analysis. We found that the traffic light labelling system (TLS), nutrient warning (NW), and health warning (HW) were associated with an increased probability of selecting more healthful products (odds ratios [ORs] and 95% confidence intervals [CIs]: TLS, 1.5 [1.2, 1.87]; NW, 3.61 [2.82, 4.63]; HW, 1.65 [1.32, 2.06]). Nutri-Score (NS) and warning labels appeared effective in reducing consumers' probability of selecting less healthful products (NS, 0.66 [0.53, 0.82]; NW,0.65 [0.54, 0.77]; HW,0.64 [0.53, 0.76]). NS and NW were associated with an increased overall healthfulness (healthfulness ratings of products purchased using models such as FSAm-NPS/HCSP) by 7.9% and 26%, respectively. TLS, NS, and NW were associated with a reduced energy (total energy: TLS, -6.5%; NS, -6%; NW, -12.9%; energy per 100 g/ml: TLS, -3%; NS, -3.5%; NW, -3.8%), sodium (total sodium/salt: TLS, -6.4%; sodium/salt per 100 g/ml: NS: -7.8%), fat (total fat: NS, -15.7%; fat per 100 g/ml: TLS: -2.6%; NS: -3.2%), and total saturated fat (TLS, -12.9%; NS: -17.1%; NW: -16.3%) content of purchases. The impact of TLS, NS, and NW on purchasing behaviour could be explained by improved understanding of the nutrition information, which further elicits negative perception towards unhealthful products or positive attitudes towards healthful foods. Comparisons across label types suggested that colour-coded labels performed better in nudging consumers towards the purchase of more healthful products (NS versus NW: 1.51 [1.08, 2.11]), while warning labels have the advantage in discouraging unhealthful purchasing behaviour (NW versus TLS: 0.81 [0.67, 0.98]; HW versus TLS: 0.8 [0.63, 1]). Study limitations included high heterogeneity and inconsistency in the comparisons across different label types, limited number of real-world studies (95% were laboratory studies), and lack of long-term impact assessments. CONCLUSIONS Our systematic review provided comprehensive evidence for the impact of colour-coded labels and warnings in nudging consumers' purchasing behaviour towards more healthful products and the underlying psychological mechanism of behavioural change. Each type of label had different attributes, which should be taken into consideration when making front-of-package nutrition labelling (FOPL) policies according to local contexts. Our study supported mandatory front-of-pack labelling policies in directing consumers' choice and encouraging the food industry to reformulate their products.

Abstract
Consumers nowadays have more awareness for healthy foods and demanded healthier food choices to avoid health-related problems; therefore, industries had included health and nutrition claims on their products. Health and nutrition claims usually influence consumers' food choice decision. Products with health claim resulted in higher perception of healthiness and nutritional value of the product, even if the product was not considered as a healthy choice. The aim of this study was to assess whether the health and nutrition claims had led to a healthier perception or better evaluation of the product among consumers. METHODS A cross-sectional survey was conducted using an online questionnaire on 385 respondents collected through convenience sampling. The survey consisted of four parts: socio-demographic background, health awareness, understanding and usage of health and nutrition claims, and purchase intention measured through the use of a mock packaging. Data collected were analyzed using SPSS version 22. RESULTS Most of the respondents aged 18-30 (81.0%) and almost half of them were Malay (45.7%) with bachelor/master or PhD qualification (60.0%). The distribution of household income for all categories was almost similar (18.2-20.8%). There was a significant statistical relationship between health awareness and purchase intention among respondents (r=0.391, p<0.01). CONCLUSIONS Health and nutrition claims influenced consumer's perceptions and purchase intention, especially for those who were more concerned about their health, thus, more focus on policy regarding claims is needed.

Abstract
Background In January 2020, Israel launched a reform mandating Front-of-Package (FOP) labeling on food products. The current study examined the factors affecting consumers’ decision-making regarding the use of FOP labels a year after the reform was implemented. Methods The survey was conducted between December 2020 and January 2021 and included a sample of 507 participants age 21 and over. The questionnaire included Health Belief Model (HBM) constructs related to food labeling, nutrition habits, media exposure and extent of support for the reform, frequency of using FOP labels, intention to change purchasing and consumption habits in the coming year, and personal details. Results The study found that 58.5% reported using the FOP labels to some extent. In addition, 70% indicated willingness to change to healthier products in the coming year. The results of the analytical model confirm the validity of the HBM and the other behavioral constructs. In particular, the frequency of using FOP labels increases as the following factors increase: levels of perceived benefits and perceived importance of reading FOP labels, level of perceived importance of healthy nutrition, frequency of conforming to healthy nutrition, and support for the reform. Conclusions The study's findings are important for understanding the impact of the new reform and for guiding future complementary actions to increase people’s motivation to use FOP labels. More advertisement about the FOP labels in the media and also through the HMOs is needed to increase people’s awareness of the reform. In addition, information about the reform provided to the public should emphasize the benefits and health implications of using FOP labels.

The Differential Effects of Physical Activity Calorie Equivalent Labeling on Consumer Preferences for Healthy and Unhealthy Food Products: Evidence from a Choice Experiment.

Abstract
Background: Since numerical calorie labels have limited effects on less-calorie food ordering, an alternative called physical activity calorie equivalent (PACE) labels, which exhibit calories using visible symbols and the minutes of exercise to burn off the calories, may be more effective in reducing calories ordered. Methods: By using a choice experiment (CE) approach, the aims of this study were to estimate the effects of PACE labels on consumer preferences for healthy and unhealth food. Red date walnuts and potato chips were used as the representatives of healthy and unhealthy foods respectively in this study. Moreover, future time perspective (FTP) is an individual trait variable of consumers, which has been recognized as a significant driver of healthy behaviors. We also included FTP into the interaction with PACE labels. Results: Firstly, the results were opposite between the healthy and unhealthy food groups. Respondents showed significantly more positive attitudes toward red date walnuts (i.e., healthy food) with PACE labels, while they showed significantly more negative preferences for chips (i.e., unhealthy food) with PACE labels. Secondly, people with higher FTP are preferred red date walnuts with PACE labels, while PACE labels on chips could undermine the preferences of respondents with higher FTP. Thirdly, we found that women (vs. men) were less inclined to choose healthy food with standard calorie labels and labels showing the minutes of running to burn off the calories, as well as that the elderly (vs. younger) people in the healthy food group preferred the labels showing the minutes of running to burn off the calories. People with a higher body mass index (BMI) were reluctant to purchase walnuts with the information about the minutes of walking. Conclusions: Results from this study showed that PACE labels have significant effects on consumers’ preferences for food products.

Abstract
Pasta represents a staple food in many populations and, in recent years, an increasing number of pasta items has been placed on the market to satisfy needs and trends. The aims of this work were: (i) to investigate the nutritional composition of the different types of pasta currently sold in Italy by collecting the nutrition facts on their packaging; (ii) to compare energy, nutrient and salt content per 100 g and serving in fresh and dried pasta; (iii) to compare the nutrition declaration in pairs of products with and without different declarations (i.e., gluten free (GF), organic, and nutrition claims (NC)). A total of 756 items, made available by 13 retailers present on the Italian market, were included in the analysis. Data showed a wide difference between dried and fresh pasta, with high inter-type variability. A negligible amount of salt was observed in all types of pasta, except for stuffed products, which had a median high quantity of salt (>1 g/100 g and ~1.5 g/serving). Organic pasta had higher fibre and lower protein contents compared to conventional pasta. GF products were higher in carbohydrate and fat but lower in fibre and protein than not-GF products, while only a higher fibre content was found in pasta with NC compared to products not boasting claims. Overall, the results show high variability in terms of nutrition composition among the pasta items currently on the market, supporting the importance of reading and understanding food labels for making informed food choices.

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
BACKGROUND Positive front-of-pack (FOP) labels, including Singapore's Healthier Choice Symbol (HCS), target a subset of healthier products whose consumption is to be encouraged. However, this may inadvertently lead to excess caloric intake, which could be addressed by including an additional label identifying calories per serving. We test this hypothesis by adding a Physical Activity Equivalent (PAE) label, an indicator of calorie content, to all products available in an on-line grocery store. METHODS We conducted a randomized controlled trial using a 3 arm within-subject crossover design in adult Singapore residents recruited online. Participants shopped once in each condition in an experimental online grocery store in random order: 1) no FOP label (Control); 2) Select products displaying HCS labels (HCS-only); 3) Condition 2 with additional information displaying PAEs per serving on every product (HCS+PAE). 117 participants were recruited and data from 317 shops were analyzed. We used first-differenced regressions to assess the impact of the conditions on calories per serving (primary) and on other measures of diet quality. RESULTS The HCS-only condition led to a statistically significant five-percentage point increase in the proportion of HCS products purchased (95% CI, 1%: 9%). However, neither the HCS-only (3.45; 95% CI, -12.52: 19.43) nor HCS + PAE (8.14; 95% CI, -5.25: 21.54) condition led to a change in the number of calories per serving purchased or changes in other measures of diet quality. CONCLUSIONS Positive labels, like the HCS, are likely to increase purchases of labelled products. However, these changes may not lead to improvements in diet quality or calorie intake. Combining positive labels with additional PAE information does not appear to address this concern.

Abstract
OBJECTIVE To examine the impact of front-of-package (FOP) labels on perceived healthfulness, purchasing intentions and understanding of common FOP systems. DESIGN A parallel, open-label design randomised participants to different FOP labelling conditions: 'high in' warning labels (WL), multiple traffic light labelling (TLL), health star ratings (HSR) (all displayed per serving) or control with no interpretive FOP labelling. Participants completed a brief educational session via a smartphone application and two experimental tasks. In Task 1, participants viewed healthy or unhealthy versions of four products and rated healthiness and purchasing intention on a seven-point Likert-type scale. In Task 2, participants ranked three sets of five products from healthiest to least healthy. SETTING Online commercial panel. PARTICIPANTS Canadian residents ≥ 18 years who were involved in household grocery shopping, owned a smartphone and met minimum screen requirements. RESULTS Data from 1997 participants (n 500/condition) were analysed. Task 1: across most product categories, the TLL and HSR increased perceived healthiness of healthier products. All FOP systems decreased perceived healthiness of less healthy products. Similar, albeit dampened, effects were seen regarding purchasing intentions. Task 2: participants performed best in the HSR, followed by the TLL, WL and control conditions. Lower health literacy was associated with higher perceived healthiness and purchasing intentions and poorer ranking task performance across all conditions. CONCLUSIONS All FOP labelling systems, after a brief educational session, improved task performance across a wide spectrum of foods. This effect differed depending on the nutritional quality of the products and the information communicated on labels.Trial Registration: NCT03290118.

Abstract
What makes food design different from other types of industrial product design? Based on over twenty years of professional design practice and food experience research, the authors present a variety of insights ‐ clustered in five overarching themes ‐ that provide an invaluable view on the specifics of the food realm for practicing designers in this field. First of all, foods are based on materials that used to be alive, which makes them highly perishable. Before the widespread introduction of mass transportations systems, foods were usually produced and consumed in the same region. But food technologists continuously try to improve the ways to preserve foods and invest in packaging that protects them in order to increase shelf life and to make them more widely available, while consumers seem to demand more and more freshness. The second challenge is presented by the need to make the food system more sustainable, addressing agricultural production and its impact on biological diversity and the quality of the living environment and also focusing on the amount of waste generated in terms of food or its packaging material. Third, the food people eat is absorbed and transformed into the building blocks of their bodies. Food fulfils a basic human need, and thus, there is a challenge to provide people access to the right amount of safe and nutritious food, in order to keep them healthy. Fourth, food is a source of sensory stimulation that enriches people’s lives. This provides a new sensory spectrum to design for ‐ including flavour and mouthfeel ‐ and it challenges designers to trigger appetite, rather than aesthetics. The fifth challenge addresses preparation practices and the associated cultural differences. Because food stuffs can be prepared in multiple ways, many different products can be created, varying from raw to highly processed, and addressing multiple consumer needs, eating occasions and market segments. These five themes provide interesting challenges for designers that should be tackled in order to provide a healthy and sustainable future for the next generations on this planet.

Factors that Influence the Perceived Healthiness of Food-Review. Nutrients 2020; 12:nu12061881.

Abstract
The interest of consumers is the consumption of healthy food, whereas the interest of food manufacturers is that consumers recognize the produced “healthier” food items on the shelves, so they can satisfy their demands. This way, identifying the factors that influence the perceived healthiness of food products is a mutual interest. What causes consumers to consider one product more beneficial to health than another? In recent years, numerous studies have been published on the topic of the influence of several health-related factors on consumer perception. This analysis collected and categorized the research results related to this question. This review collects 59 articles with the help of the search engines Science Direct, Wiley Online Library, MDPI and Emerald Insight between 1 January 2014 and 31 March 2019. Our paper yielded six separate categories that influence consumers in their perception of the healthiness of food items: the communicated information—like FoP labels and health claims, the product category, the shape and colour of the product packaging, the ingredients of the product, the organic origin of the product, and the taste and other sensory features of the product.

Abstract
Efforts to shape the food environment are aimed at reducing diet-related co-morbidities. Front-of-package labeling (FOPL) may support the consumers to make an informed decision at the point of purchase and encourage industry to reformulate food products. The Israeli Ministry of Health (MOH) implemented a unique FOPL system, using two colors: A mandatory warning (red) label alongside a voluntary positive (green) label. An independent Scientific Committee, from academia, the healthcare system, and MOH was appointed to determine the core principles for the positive FOPL. The criteria were based on the Mediterranean diet principles, with adjustments to the Israeli dietary habits, focusing on the health advantages of the food and considering its processing level. The food products eligible for positive FOPL are foods in their natural form or with added spices or herbs, or those that underwent minimal processing, with no food additives. Based on population consumption data, 19.8% of food products were eligible for positive FOPL; of them, 54% were fruits and vegetables, 20% dairy, and 14% grains. An evaluation plan is needed to assess the degree of acceptance of the positive FOPL by the industry, retailers, and the public, and its impact on food consumption and on public health.

Abstract
Several studies have demonstrated the usefulness of nutritional claims (NCs) to help consumers make more informed food decisions. However, fewer studies have investigated the effect of personal and psychological consumer characteristics on their food purchase decision. Hence, the main aim of this study is to examine the impact of body image, emotional eating style, anxiety traits, and body mass index on consumer preferences for multiple NCs on the front of the package (FOP) of hedonic (potato chips) and utilitarian (toasted bread) products carrying the same NCs. Therefore, a real choice experiment (RCE) has been used and the willingness-to-pay-space model was estimated to analyse the interaction between personal and psychological characteristics and consumer preferences. The main finding suggests differences in purchase behaviour between potato chips and toasted bread. In particular, consumers are willing to pay more for toasted bread with one NC than potato chips with one NC. Moreover, personal and psychological consumer characteristics influence the purchase behaviour regarding food products with nutritional claims. However, only the anxiety trait appears to explain the differences between the selection of both types of food products. In line with this new evidence, we proposed some behavioural, political, and managerial implications.

Prevalence of Product Claims and Marketing Buzzwords Found on Health Food Snack Products Does Not Relate to Nutrient Profile. Nutrients 2020; 12:nu12051513.

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 Several front-of-pack (FOP) labels identify healthier options by comparing foods within product categories. Alternative approaches label healthier options by comparing across categories. Which approach is superior remains unknown. The objective of this study was to test the effect of a within-category versus across-category FOP lower calorie label on 1) the percentage of labeled products purchased, 2) several measures of calories purchased (total, per dollar and per serving), and 3) total spending. We also tested the moderating effects of hunger and mood on purchasing patterns. METHODS Using an online grocery store, we conducted a 3 × 3 crossover trial involving actual purchases with 146 participants randomly exposed to: 1) no labeling control; 2) within-category lower calorie labels, and; 3) across-category lower calorie labels. We labeled the 20% of products with the lowest calories per serving within or across categories. Purchases were compared using a fixed effects regression on first-differenced outcomes. RESULTS Relative to the control condition, there was a 3 percentage point increase (p = 0.01) in labelled products purchased in the within-category arm and a non-significant decrease of 1 percentage point (p = 0.711) in the across-category arm. There was no significant difference in the proportion of labeled products purchased between the two labelling conditions. Neither strategy resulted in reductions in any measure of calories purchased or in total spending. When limited to beverages, there was a 398 cal reduction (p = 0.01) in the within-category arm and a 438 cal reduction (p < 0.01) in the across-category arm versus the control. Mood and hunger did not modify the effects for either strategy. CONCLUSIONS Results provide evidence that both labelling strategies have the potential to influence food purchasing patterns. However, we cannot definitely state that one labelling approach is superior or even that an increase in the proportion of labelled products purchased will lead to a reduction in calories purchased. TRIAL REGISTRATION The American Economic Association's registry for randomized controlled trials, RCT ID: AEARCTR-0002325; Prospectively Registered October 06, 2017. In compliance with ICMJE policy, the trial was also registered on Clinicaltrials.gov, RCT ID: [NCT04165447]. Retrospectively Registered 11 November 2019.

Abstract
The Australia New Zealand Food Standards Code does not regulate on-pack claims describing the amount of whole grain in foods. In July 2013, The Grains & Legumes Nutrition Council™ (GLNC) established a voluntary Code of Practice for Whole Grain Ingredient Content Claims (the Code) providing guidance for whole grain claims, with cut-off values and suggested wording ≥8 g, ≥16 g, and ≥24 g per manufacturer serve (contains; high and very high in whole grain), based on a 48 g whole grain daily target intake. The aim of this impact assessment was to report the uptake of the Code by manufacturers, changes in numbers of whole grain products, and claims on-pack since 2013, including compliance. The impact assessment was undertaken in August 2019, comparing current registered manufacturers (“users”) and their products to the total number of products in the market deemed eligible for registration through GLNC product audits since 2013. Reporting included breakfast cereals, bread products, crispbreads, crackers, rice/corn cakes, rice, pasta, noodles, couscous, other grains (e.g., quinoa, buckwheat, freekeh), and grain-based muesli bars. As of 30 June 2019, there were 33 registered users and 531 registered products in Australia and New Zealand representing 43% of the eligible manufacturers and 65% of the eligible whole grain foods. Three-quarters (78% and 74%) of the eligible breakfast cereals and bread products were registered with the Code in 2019, followed by 62% of grain-based muesli bars. Only 39% of crispbread, crackers, rice/corn cakes, and rice, pasta, noodles, couscous, and other grains were registered. From 2013 there has been a 71% increase in the number of whole grain foods making claims, demonstrating strong uptake by industry, with clearer, more consistent, and compliant on-pack communication regarding whole grain content.

Abstract
Objetivos. Sintetizar la información disponible sobre el efecto del etiquetado nutricional frontal en la elección, compra y consumo de alimentos y bebidas, y el estado nutricional de los consumidores, e identificar los factores que influyen en su efectividad. Métodos. Se realizó una sinopsis de revisiones sistemáticas (RS) conforme a las recomendaciones PRISMA. La búsqueda bibliográfica se realizó en Medline (Pubmed), The Cochrane Library, LILACS, EBSCOhost y Scopus, limitada a estudios publicados en español o inglés sin restricción por fecha de publicación. La calidad metodológica se evaluó utilizando la herramienta AMSTAR 2. Resultados. Se incluyeron siete RS. El etiquetado frontal facilitó la elección de alimentos saludables y tuvo un efecto variable sobre las dimensiones de consumo y compra. Ninguna RS evaluó el efecto sobre el estado nutricional. El costo y sabor, los hábitos alimentarios, el nivel educativo y los sistemas dominantes de procesamiento de información en el consumidor influyeron en su efectividad. La mayoría de RS mostraron limitaciones metodológicas y un nivel de confianza críticamente bajo. Conclusiones. El etiquetado frontal tuvo efecto positivo en la elección de alimentos saludables, con resultados variables en las dimensiones de compra y consumo. Se necesitan estudios locales con una adecuada calidad metodológica para identificar el formato de etiquetado más efectivo en cada país. Su implementación como política de salud pública debe acompañarse de estrategias para mejorar el acceso a alimentos saludables, promover la actividad física y brindar educación nutricional a los consumidores.

Abstract
Front-of-package (FOP) food labels are symbols, schemes, or systems designed to communicate concise and useful nutrition-related information to consumers to facilitate healthier food choices. FOP label policies have been implemented internationally that could serve as policy models for the U.S. However, the First Amendment poses a potential obstacle to U.S. government-mandated FOP requirements. We systematically reviewed existing international and major U.S.-based nutrition-related FOP labels to consider potential U.S. policy options and conducted legal research to evaluate the feasibility of mandating a FOP label in the U.S. We identified 24 international and 6 U.S.-based FOP labeling schemes. FOP labels which only disclosed nutrient-specific data would likely meet First Amendment requirements. Certain interpretive FOP labels which provide factual information with colors or designs to assist consumers interpret the information could similarly withstand First Amendment scrutiny, but questions remain regarding whether certain colors or shapes would qualify as controversial and not constitutional. Labels that provide no nutrient information and only an image or icon to characterize the entire product would not likely withstand First Amendment scrutiny.

Consumers' purchase decisions for products with nutrition and health claims: What role do product category and gaze duration on claims play? Appetite 2019; 141:104337. [PMID: 31260708 DOI: 10.1016/j.appet.2019.104337] [Citation(s) in RCA: 16] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2019] [Revised: 06/20/2019] [Accepted: 06/27/2019] [Indexed: 11/22/2022]
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
The addition of Health Star Rating (HSR) labelling to menus at fast food outlets is feasible, however how this would impact consumer menu selection remains unclear. The aim of this study was to test whether the addition of HSR labelling to kilojoule (kJ) labelling on menus at fast food outlets would prompt consumers to select healthier meals. Using a between-subjects experimental design, 1007 adults aged 18-49 were allocated to one of four menu labelling conditions: (i) no labelling; (ii) kilojoule labelling; (iii) HSR labelling; and (iv) kilojoule + HSR labelling. Respondents were presented with their assigned menu online and instructed to select an evening meal as they would at a fast food restaurant. The main analyses tested differences by menu labelling condition in the total mean kilojoule content and Nutrient Profiling Score (NPS) of respondents' evening meal selections using one-way ANOVA. The mean kilojoule content of meals did not differ significantly by menu labelling condition. However, respondents in the kilojoule + HSR labelling condition selected healthier meals (lower mean NPS) than those who viewed menu boards with kilojoule labelling only (M = 2.88 cf. M = 3.78, p = 0.046). In addition, in a post hoc per-protocol analysis of respondents who reported using menu labelling to assist their meal selection, respondents shown kilojoule + HSR menu labelling selected meals with a significantly lower kilojoule content compared to those shown HSR labelling only (4751 kJ cf. 5745 kJ, p = 0.038). Findings provide evidence that adding HSRs to kilojoule labelling on menu boards at fast food outlets has the potential to assist adults to make healthier evening meal selections.

Abstract
Qualified health claims (QHC) describe diet-disease relationships and summarize the quality and strength of evidence for a claim. Companies assert that QHCs increase sales and take legal action to ensure claims reflect their interests. Yet, there is no empirical evidence that QHCs influence consumers. Using green tea as a case study, this study investigated the effects of QHCs on purchase intentions among adults 55 years and older living in the US. An online survey using a between-subjects design examined QHCs about the relationship between green tea and the reduced risk of breast and/or prostate cancer or yukichi fruit juice and the reduced risk of gastrocoridalis, a fictitious relationship. QHCs written by a green tea company generated greater perceptions of evidence for the relationship, greater confidence in green tea and cancer, and increased purchase intentions for green tea than other QHCs. Factors that mitigated the claim's effects on purchase intentions are: Race/ethnicity; age; importance of health claims; supplement use; health; worry about health/becoming sick with cancer; worry that led to dietary change; green tea consumption; and familiarity with the green tea-cancer. Consumers who made health-related dietary change in the past year and consider health claims important indicated greater purchase intentions than others.

Abstract
BACKGROUND The extent to which low-calorie sweeteners (LCSs) are helpful or harmful for weight management and metabolic health is unclear, because LCS effects may depend on the context in which they are consumed. OBJECTIVE To develop a conceptual framework for LCS consumption. METHODS Young adults ages 18-35 y, who reported LCS consumption, were recruited from a private, urban, university in the mid-Atlantic United States. Concept mapping, a mixed-method approach was used to identify, organize, and quantify determinants of LCS consumption. First, participants (n = 68) identified reasons for their LCS consumption through brainstorming; content analysis of those reasons identified 37 specific determinants of LCS consumption. Second, participants (n = 93) sorted all 37 determinants conceptually. Third, participants (n = 97) rated the extent to which each of the 37 determinants was reflective of their own consumption. Similarity matrices, multidimensional scaling, and hierarchical cluster analysis produced a series of 2-dimensional concept maps (SWEET MAPS). RESULTS The SWEET MAPS identified 37 determinants, organized within 8 factors reflective of 3 overarching motives: perceived health benefits, palatability, and accessibility of LCSs. At the determinant level, the most highly rated determinants that exceeded the boundary (rating >3.0) were: "I want something that tastes sweet," "I am trying to maintain/control my weight," "They contain fewer calories," "They are available," and "I want to save calories because I am eating a high-calorie meal." CONCLUSIONS LCS consumption is a function of many inter-related determinants spanning biological, psychological, and social domains. The SWEET MAPS are an important and novel use of concept mapping methods that can be used to inform the design and interpretation of future studies evaluating LCS effects.

Abstract
Many different front-of-pack (FOP) nutrition labels have been introduced worldwide. To continue the debate on the most effective FOP labels for increased consumer health, full comprehension of their visual and functional features is relevant. This paper compares and provides an overview of all FOP labels currently in practice or in preparation in Europe, by means of the visually oriented Funnel Model. The Funnel Models were completed in collaboration with the respective FOP labelling initiatives. In total, six positive FOP labels, two mixed FOP labels and one negative FOP label were compared. There are multiple similarities and differences between the FOP labels, with each FOP label being characterised by a unique set of criteria and methodological approach. This Funnel Model comparison provides the knowledge to ultimately find more common ground for all stakeholders involved in the FOP labelling debate. Importantly, implementation and evaluation activities carried out by FOP labelling organisations are crucial success factors for FOP labels in practice. We conclude that more attention should be paid to methodological differences between FOP labels and recommend that the current comparison is expanded to a global level and periodically updated, as the variety of FOP labels in the global marketplace is changing constantly.

Abstract
A Physical Activity Calorie Equivalent (PACE) label shows the minutes of physical activity required to burn off the caloric content of a particular food. This study investigated the influence of PACE labelling on liking and consumption of discretionary snack foods in a group of more health focused and less health focused consumers. Participants (n = 97) tasted and rated (i.e., liking, prospective consumption) a range of snack foods with or without a PACE label. Total sampling consumption was also measured. Participants completed a shortened version of the International Physical Activity Questionnaire and the General Health Interest Scale questionnaire. Paired samples t-test, independent samples t-tests, a General Linear Model and Chi-Square tests were used to check for statistical significance. For more health focused participants (n = 57), the PACE label decreased only liking (p = 0.02). The PACE label was not effective in reducing liking (p = 0.49), prospective consumption (defined as the amount of the sample participants thought that they could consume) (p = 0.10) or consumption (p = 0.41) of energy-dense discretionary snack foods for less health focused individuals (n = 40). The level of participants’ physical activity did not facilitate the influence of PACE labelling on liking, consumption or prospective consumption. The PACE label was found to not be effective among less health focused individuals or the overall sample population. Therefore, the PACE label may not be an effective labelling strategy to reduce the liking or consumption of discretionary snack foods.

Health Star Rating in Grain Foods-Does It Adequately Differentiate Refined and Whole Grain Foods? Nutrients 2019; 11:nu11020415.

Abstract
The Australian front-of-pack labelling system, Health Star Rating (HSR), does not include whole grain (WG) in its algorithm, but uses dietary fibre (DF), despite Dietary Guidelines recommending WG over refined grain (RG) foods. This study aimed to determine how effectively HSR differentiates WG and RG foods. Product label data were collected 2017–18 from bread, rice, pasta, noodles, flour and breakfast cereals (n = 1127). Products not displaying HSR, DF per 100 g, and %WG ingredients were excluded, leaving a sample of 441 products; 68% were WG (≥8 g/manufacturer serving). There was a significant difference (p < 0.001) in HSR between WG bread and breakfast cereal over RG varieties, yet the mean difference in stars depicted on the pack was only 0.4 for bread and 0.7 for breakfast cereal. There was no difference for rice (p = 0.131) or flour (p = 0.376). Median HSR also poorly differentiated WG. More WG foods scored 4–5 stars compared to RG, yet there was notable overlap between 3.5–5 stars. DF content between RG and WG subcategories was significantly different, however wide variation and overlap in DF highlights that this may not be a sufficient proxy measure, raising concerns that the HSR algorithm may not adequately communicate the benefits for consumers of swapping to WG foods.

Abstract
BACKGROUND AND OBJECTIVES Selected beverages, such as sugar-sweetened beverages, have been reported to influence kidney disease risk, although previous studies have been inconsistent. Further research is necessary to comprehensively evaluate all types of beverages in association with CKD risk to better inform dietary guidelines. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS We conducted a prospective analysis in the Jackson Heart Study, a cohort of black men and women in Jackson, Mississippi. Beverage intake was assessed using a food frequency questionnaire administered at baseline (2000-2004). Incident CKD was defined as onset of eGFR<60 ml/min per 1.73 m2 and ≥30% eGFR decline at follow-up (2009-13) relative to baseline among those with baseline eGFR ≥60 ml/min per 1.73 m2. Logistic regression was used to estimate the association between the consumption of each individual beverage, beverage patterns, and incident CKD. Beverage patterns were empirically derived using principal components analysis, in which components were created on the basis of the linear combinations of beverages consumed. RESULTS Among 3003 participants, 185 (6%) developed incident CKD over a median follow-up of 8 years. At baseline, mean age was 54 (SD 12) years, 64% were women, and mean eGFR was 98 (SD 18) ml/min per 1.73 m2. After adjusting for total energy intake, age, sex, education, body mass index, smoking, physical activity, hypertension, diabetes, HDL cholesterol, LDL cholesterol, history of cardiovascular disease, and baseline eGFR, a principal components analysis-derived beverage pattern consisting of higher consumption of soda, sweetened fruit drinks, and water was associated with significantly greater odds of incident CKD (odds ratio tertile 3 versus 1 =1.61; 95% confidence interval, 1.07 to 2.41). CONCLUSIONS Higher consumption of sugar-sweetened beverages was associated with an elevated risk of subsequent CKD in this community-based cohort of black Americans.

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. This trial was registered as ACTRN12617000015347 (www.anzctr.org.au/Trial/Resgistration/TrialReview.aspx?id=372055&isReview=true).

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
Two voluntary front-of-pack nutrition labels (FOPNL) are present in Australia: the government-led Health Star Ratings (HSR) and food industry-led Daily Intake Guide (DIG). Australia's two largest supermarkets are key supporters of HSR, pledging uptake on all supermarket own brand foods (SOBF). This study aimed to examine prevalence of FOPNL on SOBF, and alignment with patterns of nutritional quality. Photographic audits of all SOBF present in three large supermarkets were conducted in Perth, Western Australia, in 2017. Foods were classified as nutritious or nutrient-poor based on the Australian Guide to Healthy Eating (AGTHE), NOVA level of food processing, and HSR score. Most (81.5%) SOBF featured FOPNL, with only 55.1% displaying HSR. HSR was present on 69.2% of Coles, 54.0% of Woolworths, and none of IGA SOBF. Half (51.3%) of SOBF were classified as nutritious using the AGTHE, but using NOVA, 56.9% were ultra-processed foods. Nutrient-poor and ultra-processed SOBF were more likely than nutritious foods to include HSR, yet many of these foods achieved HSR scores of 2.5 stars or above, implying they were a healthy choice. Supermarkets have a powerful position in the Australian food system, and they could do more to support healthy food selection through responsible FOPNL.
