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
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
Background :The effectiveness of Front-of-Pack nutrition Labels (FoPLs) may be influenced by national context. In light of the ongoing efforts to harmonize FoPLs across Europe, this study aimed to compare the effectiveness of five FoPLs (Health Star Rating system, Multiple Traffic Lights, Nutri-Score, Reference Intakes, Warning symbols) on consumer understanding and food choice in 12 European countries.
Methods : In 2018–2019, for three food categories, approximately 1000 participants per country were asked to select which food they would prefer to purchase between three products with distinct nutritional quality profiles, and then to rank the products by nutritional quality. Participants (N = 12,391 in total) completed these tasks first with no FoPL and then, after randomization to one of the five FoPLs, with a FoPL on the food packages. Associations between FoPLs and change in (i) nutritional quality of food choices and (ii) ability to correctly rank the products by nutritional quality were assessed with logistic regression models adjusted for sociodemographic and lifestyle characteristics of participants, conducted overall and by country.

Abstract
In Europe, discussions are currently ongoing to harmonize front-of-pack nutritional labelling, while some countries have adopted or are considering implementing the Nutri-Score. However, its adaptability to multiple nutritional contexts in Europe requires further investigation. This study aimed to evaluate the applicability of the Nutri-Score in various European countries, regarding its ability to discriminate the nutritional quality of foods and its consistency with national dietary recommendations. The European Food Information Resource (EUROFIR) nutritional composition databases from eight European countries (Finland, France, Norway, Poland, Portugal, Slovakia, Sweden, and Switzerland) were used. The distribution of foods across the Nutri-Score classes within food groups was assessed, as well as the discriminating performance of the label, and the adequacy of nutritional recommendations. The Nutri-Score demonstrated high discriminating ability for all food groups, with similar trends in the eight countries, and consistency with nutritional recommendations. For instance, fruit and vegetable products were mainly classified in the two healthiest Nutri-Score categories, while sugar and animal fat products were mainly classified in the two less healthy categories of the Nutri-Score. Our results support the fact that the Nutri-Score would be a relevant tool to discriminate the nutritional quality of products within and across relevant food groups in different European countries, with consistency with nutritional recommendations.

Abstract
Objective To determine if the Food Standards Agency nutrient profiling system (FSAm-NPS), which grades the nutritional quality of food products and is used to derive the Nutri-Score front-of-packet label to guide consumers towards healthier food choices, is associated with mortality.jective To determine if the Food Standards Agency nutrient profiling system (FSAm-NPS), which grades the nutritional quality of food products and is used to derive the Nutri-Score front-of-packet label to guide consumers towards healthier food choices, is associated with mortality.
Conclusions In this large multinational European cohort, consuming foods with a higher FSAm-NPS score (lower nutritional quality) was associated with a higher mortality for all causes and for cancer and diseases of the circulatory, respiratory, and digestive systems, supporting the relevance of FSAm-NPS to characterise healthier food choices in the context of public health policies (eg, the Nutri-Score) for European populations. This is important considering ongoing discussions about the potential implementation of a unique nutrition labelling system at the European Union level.

Abstract
BACKGROUND :
Helping consumers make healthier food choices is a key issue for the prevention of cancer and other diseases. In many countries, political authorities are considering the implementation of a simplified labelling system to reflect the nutritional quality of food products. The Nutri-Score, a five-colour nutrition label, is derived from the Nutrient Profiling System of the British Food Standards Agency (modified version) (FSAm-NPS). How the consumption of foods with high/low FSAm-NPS relates to cancer risk has been studied in national/regional cohorts but has not been characterized in diverse European populations.
METHODS AND FINDINGS :
This prospective analysis included 471,495 adults from the European Prospective Investigation into Cancer and Nutrition (EPIC, 1992-2014, median follow-up : 15.3 y), among whom there were 49,794 incident cancer cases (main locations : breast, n = 12,063 ; prostate, n = 6,745 ; colon-rectum, n = 5,806). Usual food intakes were assessed with standardized country-specific diet assessment methods. The FSAm-NPS was calculated for each food/beverage using their 100-g content in energy, sugar, saturated fatty acid, sodium, fibres, proteins, and fruits/vegetables/legumes/nuts. The FSAm-NPS scores of all food items usually consumed by a participant were averaged to obtain the individual FSAm-NPS Dietary Index (DI) scores. Multi-adjusted Cox proportional hazards models were computed. A higher FSAm-NPS DI score, reflecting a lower nutritional quality of the food consumed, was associated with a higher risk of total cancer (HRQ5 versus Q1 = 1.07 ; 95% CI 1.03-1.10, P-trend < 0.001). Absolute cancer rates in those with high and low (quintiles 5 and 1) FSAm-NPS DI scores were 81.4 and 69.5 cases/10,000 person-years, respectively. Higher FSAm-NPS DI scores were specifically associated with higher risks of cancers of the colon-rectum, upper aerodigestive tract and stomach, lung for men, and liver and postmenopausal breast for women (all P < 0.05). The main study limitation is that it was based on an observational cohort using self-reported dietary data obtained through a single baseline food frequency questionnaire ; thus, exposure misclassification and residual confounding cannot be ruled out.
CONCLUSIONS :
In this large multinational European cohort, the consumption of food products with a higher FSAm-NPS score (lower nutritional quality) was associated with a higher risk of cancer. This supports the relevance of the FSAm-NPS as underlying nutrient profiling system for front-of-pack nutrition labels, as well as for other public health nutritional measures.

Abstract
Front-of-Package labels (FoPLs) provide simplified nutritional information to consumers to help them make healthier food choices. Investigating consu-mers’ understanding of this information is of major importance. This study compared consumers’ objective understanding of five FoPLs (Health Star Rating System [HSR], Multiple Traffic Lights [MTL], Nutri-Score, Reference Intakes [RIs], warning symbol). In 2018, 1,000 German participants were en-rolled in an online survey and asked to rank three sets of products according to their nutritional quality, first in the absence of any labelling, and then with an FoPL displayed on-pack (randomized). Change in ability to correctly rank products was assessed using ordinal logistic regression. For all food catego-ries, the Nutri-Score performed best, followed by the MTL, warning Symbol, HSR and RIs. The Nutri-Score emerged as the most effective FoPL in conveying information on the nutritional quality of foods for German consumers.

Abstract
Background :There is currently a societal debate in Germany concerning the interest to introduce a comprehensive and simplified nutritional information label on foods. Consumer associations and some manufacturers are supporting the Nutri-Score, a summary, graded, colours-coded front-of-pack label (FoPL) adopted by public health authorities in France, Belgium and Spain. The Nutri-Score is using a Nutrient Profiling System (NPS) to define five different categories of nutritional quality (from ‘Dark green’ associated with the letter A to ‘dark orange’ with an E). The ability of the Nutri-Score to discriminate nutritional quality of foods was demonstrated in the French context. The objectives of this study were to verify its ability to discriminate the nutritional quality of foods and beverages currently present on the market in Germany and its consistency with German Food-Based Dietary Guidelines (FBDG).
Method : Nutritional composition of 8587 usual foods available on the German market collected from the web-based collaborative project Open Food Facts, were retrieved. Data were collected from 2012 to 2019, with regular updates each time a product is scanned again by a contributor. Distribution of products across the five Nutri-Score categories according to consumer-based food groups was assessed. The ability of the FoPL to discriminate the nutritional quality of foods and beverages was estimated by the number of available colours of the Nutri-Score in each food group and sub-groups.
Result : Overall, the classification of foods according to the Nutri-Score was consistent with German FBDG : foods which consumption is recommended were more favourably classified (e.g. 79.7% of products composed mainly of fruits and vegetables were classified as A or B) than foods which consumption should be limited (e.g. 93.4% of sugary snacks were classified as D or E).
Moreover, we observed that the nutrient profiling system underpinning the Nutri-Score was able to display the variability in nutritional quality of foods within the same food groups, with good discriminating performance (at least three colours represented with the Nutri-Score).
Conclusions : The Nutri-Score label displays a high ability in discriminating nutritional quality of foods across food groups and within a food group in the German market. This element is a key step in the validation process of a front-of-pack label, so that the Nutri-Score is an efficient tool which could help German consumers to make healthier choices.

- The impact of the Nutri-Score nutrition label on perceived healthiness and purchase intentions
Appetite (2021) - Joyce De Temmerman, Eva Heeremans, Hendrik Slabbinck, Iris Vermeir

Abstract
Making healthier food choices easier at the time of purchase is a challenge for public policy makers. The Nutri-Score can be an effective tool for guiding and steering consumers toward more informed, healthier purchasing decisions. This research investigates the impact of the presence of the Nutri-Score and its five categories on consumers’ perceived healthiness perceptions and purchase intentions. Consumers in the EU took part in two online experiments, in which they rated products from different categories, with or without Nutri-Scores, in terms of their perceived healthiness and purchase intentions. The presence of the Nutri-Score enabled respondents to assess the healthiness of products better ; furthermore, it offers the potential to boost sales of healthy products, without affecting sales of unhealthy products. Perceived healthiness mediates the relationship between Nutri-Score categories and purchase intentions, and focusing on the healthiness of products can give producers a competitive advantage, regardless of whether it is a manufacturer brand or a private label. These findings offer actionable insights for public policy makers and manufacturers ; they also suggest the need to embrace the Nutri-Score as the standard front-of-pack label to help fight the increasing obesity pandemic.

- Bulgarian consumers’ objective understanding of front-of-package nutrition labels : a comparative, randomized study
Archives of Public Health - 2020
Andreeva VA, Egnell M, Handjieva-Darlenska T, Talati Z, Touvier M, Galan P, et al.

Abstract
Background : Bulgaria continues to lag behind other EU Member States with respect to chronic disease morbidity
and mortality prevention.
Methods : In line with efforts targeting the improvement of dietary practices, this comparative study assessed
objective understanding of five different front-of-package labels (FOPL) (Reference Intakes, Multiple Traffic Lights,
Warning label, Nutri-Score, and Health Star Rating) in a sample of 1010 Bulgarian adults. Objective understanding
was assessed by comparing the results of two nutritional quality ranking tasks (with and without FOPL) in an online
randomized experiment featuring three food categories (pizza, cakes, breakfast cereals). Multivariable ordinal logistic
regression models within and across food categories were fit.
Results : Compared with the Reference Intakes group, participants randomized to Nutri-Score exhibited the largest
improvement in product ranking ability across food categories (OR = 2.33 ; 95% CI : 1.55–3.51), followed by those
randomized to Health Star Rating (OR = 1.99 ; 95% CI : 1.32–3.00). Nutri-Score also performed best within two (pizza
and breakfast cereals) of the three food categories. The Multiple Traffic Lights and Warning label groups did not
display any significant improvement in objective understanding either within or across food categories compared
with the Reference Intakes group.
Conclusion : Nutri-Score, which is a summary, interpretive, polychromatic FOPL, emerged as the most effective
model in the Bulgarian context, with the potential to help consumers better understand the nutritional quality of
food. The findings are of particular interest to public health policymakers in the region and across Europe, as the
debate about an EU-wide FOPL model continues to gather momentum.

- The Effect of Randomly Providing Nutri-Score Information on Actual Purchases in Colombia
Nutrients. 26 févr 2019 ;11(3) - Mora-García CA, Tobar LF, Young JC.

Abstract
Recently, front-of-package (FOP) food labeling systems have captured the attention of researchers and policy makers. Several Latin American governments are currently considering employing different FOP labeling systems. However, there is much need for more research-based evidence in these countries. In this paper, we study whether food-purchasing decisions and the nutritional qualities of those purchases are influenced by randomly informing some customers and not others about an FOP label known as Nutri-Score. We also separate the information effect from the effect of being aware of the system. We combined a randomized field intervention in a university cafeteria in Bogotá, Colombia with data from an after-purchase survey and receipts. We found that randomly providing information on Nutri-Score increased total expenditure by $0.18. Additional spending on healthier items was 21% or $0.26 higher, with no change for less healthy items. Expenditure estimates were higher among customers who were aware of the system’s existence. Customers in the study were also 10% more likely to buy a healthier item than control customers were, and the concentration of protein in their purchases was greater. Information on the Nutri-Score system increased the store’s sales. This potential financial incentive may facilitate the implementation of Nutri-Score.

Abstract
Background & aims :Front-of-pack nutrition labelling is a key public health policy that can be adopted as part of a comprehensive set of measures to promote healthy diets. The Nutri-Score, a five-colour summary label based on a modified version of the British Food Standards Agency Nutrient Profiling System (FSAm-NPS), is being considered for implementation in several European countries including Spain. This study aimed to prospectively assess the association between the FSAm-NPS and mortality rate in a Spanish cohort of university graduates.
Methods :Analyses included 20,503 participants (mean [SD] age : 38 [12] years) from the SUN cohort. Dietary intake was assessed at baseline and after 10-years of follow-up with a validated semi-quantitative food-frequency questionnaire. The FSAm-NPS was calculated for each food/beverage based on their amount of energy, saturated fat, sugar, sodium, fibre, protein, fruits, vegetables, legumes, nuts, rapeseed, walnut and olive oils per 100 grams of product. The FSAm-NPS Dietary Index (DI) was computed as an energy-weighted mean of the FSAm-NPS scores of all foods and beverages consumed by each participant. Multivariable-adjusted Cox proportional hazards models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for all-cause and cause-specific mortality according to baseline and updated FSAm-NPS DI scores.
Conclusions :The consumption of food products with a higher FSAm-NPS score (lower nutritional quality) was associated with a higher rate of all-cause and cancer mortality in a large prospective cohort of Spanish, middle-aged university graduates. These findings further support the implementation of Nutri-Score in Euro-Mediterranean countries.

Abstract
Spain as other industrialized countries face a major public health challenge in the form of the increasing burden of chronic diseases, fuelled by the rising prevalence of obesity. Nutritional risk factors have been recognized as some of the main drivers of obesity and chronic diseases in the Western world. They are key levers to public health policies as they represent modifiable determinants of health that could be addressed through primary prevention interventions. In this context, France recently announced the implementation of a novel Front-of-Pack (FOP) nutrition labelling at national level to help consumers making healthier choice at the point of purchase and to incent manufacturers to improve the nutritional quality of foods they produce. The selected system, the NutriScore, five couloured label has been the object of scientific research for validation purposes. The objective of the present narrative review is to examine the existing literature on the development, validation and testing of the NutriScore. Elements of the validity of the nutrient profiling system underlying the label as well as the format of the label were investigated. Scientific evidence suggests that the nutrient profiling system underlying the Nutriscore FOP label can adequately characterize the nutritional quality of foods and may be associated at individual level with chronic diseases onset. Finally, the format of the NutriScore (and its former version, the 5-Colour Nutrition Label, 5-CNL) appears as a well-perceived and understood label. The NutriScore was associated with a higher nutritional quality of purchases in experimental and large scale trials. Altogether, these elements tend to corroborate the NutriScore as an efficient tool in public health nutrition for Spain.

Abstract
Background and objectives :Increased prevalence of obesity and its comorbidities has shown the need to implement social policies to help curb this trend. Nutritional risk factors are recognized as key drivers of obesity and other chronic diseases in Spain and in other Western countries. Front-of-package labels (FoPLs) are efficient tools to help consumers make healthier choices. To be useful in purchasing situations, consumers need to understand the information provided by FoPLs. The study objective was to assess objective understanding by consumers of five types of FoPLs, i.e. Health Star Rating system (HSR), Multiple Traffic Lights (MTL), Nutri-Score, Reference Intakes (RIs), and Warning symbol in Spain.
Methods : In 2018, 1,000 Spanish participants were recruited and requested 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 in an on-line survey. Participants were then randomized to one of the five types of FoPLs, and were requested to rank the same sets of products again, this time with a given FoPL displayed on the package. Changes in ability to correctly rank products according to FoPLs were compared between both tasks using ordinal logistic regression.
Results :For all three food categories, Nutri-Score performed significantly better, followed by MTL, the Warning symbol, HSR and RIs.
Conclusions :Nutri-Score emerged as the most efficient FoPL in conveying information on the nutritional quality of foods among Spanish consumers.

Abstract
The Spanish Ministry of Health, in November 2018, notified the officially adoption of the front-of-pack nutrition label Nutri-Score which will allow consumers to easily judge the nutritional quality of food at the time of purchase and to encourage industrialists to improve the nutritional composition of food. This article synthesizes the scientific work pertaining to the validation of the nutritional profile that underlies the computation of Nutri-Score and works that demonstrate its effectiveness and superiority in comparison to other existing logos or proposed by food companies. Likewise, it highlights its development in Spain and within the European Union and responds to the fake-news raised by its detractors. It also introduces the European Citizens’ Initiative to make it compulsory in Europe.

Astract
In Italy, discussions are currently ongoing to implement a front-of-pack nutrition label (FoPL) while a growing number of European countries are adopting the Nutri-Score. The effectiveness of the Nutri-Score among Italian consumers requires further investigation. This study compared five FoPLs among Italian participants (Health Star Rating system, multiple traffic lights, Nutri-Score, reference intakes, warning symbol) in terms of food choices and understanding of the labels by consumers. In 2019, 1032 Italian consumers completed an online survey in which they were asked to select one product they would likely purchase from a set of three foods with different nutrient profiles and then classify the products within the set according to their nutritional quality, first with no label and then with one of the five FoPLs on the pack. While no significant difference across labels was observed for food choices, the Nutri-Score demonstrated the highest overall performance in helping consumers to correctly rank the products according to their nutritional quality compared to the reference intakes (OR = 2.18 (1.50–3.17), p-value < 0.0001). Our results provide new insights on the effectiveness of the Nutri-Score, which would be a relevant tool to inform Italian consumers on the nutritional quality of food products.

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
The objective of this trial was to test two promising front-of-pack nutrition labels, 1) the United Kingdom’s Multiple Traffic Lights (MTL) label and 2) France’s Nutri-Score (NS), relative to a no-label control. We hypothesized that both labels would improve diet quality but NS would be more effective due to its greater simplicity. We tested this hypothesis via an online grocery store using a 3 × 3 crossover (within-person) design with 154 participants. Outcomes assessed via within person regression models include a modified Alternative Healthy Eating Index (AHEI)-2010 (primary), average Nutri-Score, calories purchased, and singular measures of diet quality of purchase orders. Results show that both labels significantly improve modified AHEI scores relative to Control but neither is statistically superior using this measure. NS performed statistically better than MTL and Control based on average Nutri-Score, yet, unlike MTL it did not statistically reduce calories or sugar from beverages. This suggest that NS may be preferred if the goal is to improve overall diet quality but, because calories are clearly displayed on the label, MTL may perform better if the goal is to reduce total energy intake.

Abstract
Background : Switzerland, like other high-income countries, is facing a major public health challenge with the increasing burden of non-communicable diseases. Discussions are currently on-going in Switzerland regarding the implementation of a Front-of-Pack nutrition label (FoPL) as a public health measure to guide consumers towards healthier food choices, and the Nutri-Score represents an alternative supported by multiple actors. To date, no studies have investigated the performance of the Nutri-Score among Swiss consumers. This study aimed to compare the response of Swiss consumers to five FoPLs (Health Star Rating system, Multiple Traffic Lights, Nutri-Score, Reference Intakes and Warning symbol) in terms of perception and understanding of these labels and effects on food choices.
Methods :In 2019, 1,088 Swiss consumers were recruited and asked to select one product from among a set of three foods with different nutritional profiles and then classify the products within the sets according to their nutritional quality. Tasks were performed in situations without a label and then with one of the five FoPLs–depending on the group in which they were randomized–on the pack. Finally, participants were questioned on their perceptions regarding the label to which they were exposed.
Results :All FoPLs were favorably perceived, with marginal differences between FoPLs. The Nutri-Score demonstrated the highest percentage of improvement in food choices and the highest overall performance in helping consumers rank the products according to their nutritional quality.
Conclusion :Overall, the Nutri-Score was the most efficient FoPL in informing Swiss consumers of the nutritional quality of food products, and as such could be a useful tool to improve food choices and reduce the burden of chronic diseases in Switzerland.
