Association of magnesium deficiency, tobacco smoke exposure and hypertension in children and adolescents: evidence from the NHANES 2007–2018

BackgroundRecent studies suggested that the combination of tobacco smoke exposure (TSE) and dietary nutrients intake may be related to a higher or lower risk of hypertension. However, the relationship between dietary magnesium (Mg) intake, TSE and the odds of hypertension remain unclear. This study aimed to evaluate the association of TSE, dietary Mg intake and the odds of hypertension among children and adolescents.MethodData of this study were extracted from the National Health and Nutrition Examination Surveys (NHANES) 2007–2018. Dietary Mg intake was calculated as the average of two days of dietary and supplementations intake. Serum cotinine concertation ≥ 0.05 µg/L or at least one-person smoking in the household was considered as exposing to the tobacco smoke. The weighted univariate and multivariate logistic regression models were utilized to explore the associations of dietary Mg intake, TSE and the odds of hypertension among children and adolescents with the evaluation index of odds ratio (ORs) and 95% confidence intervals (CIs). Subgroup analyses based on different age, gender and overweight were further assessed these associations.ResultsA total of 7,122 children and adolescents aged 8–17 years old and with the blood pressure measurement were included. Of which, 948 (13.31%) had hypertension. After adjusting all covariates, we observed children and adolescents exposed to tobacco smoke was related to higher odds of hypertension (OR = 1.34, 95%CI: 1.01–1.78); children and adolescents not reached the dietary Mg references intakes was related to higher odds of hypertension (OR = 1.48, (95%CI: 1.11–1.97); compared to children and adolescents non-TSE and reached the DRIs of Mg, those not reached the DRIs of Mg and exposed to tobacco smoke have the highest odds of hypertension (OR = 1.94, 95%CI: 1.30–2.89, P for trend = 0.002). These associations of dietary Mg intake, TSE and hypertension remain robust after the stratified analysis based on age, gender and overweight was conducted.ConclusionOur findings suggested there were a robust association between dietary Mg intake, TSE and hypertension in children and adolescents. Those children and adolescents with deficiency dietary Mg intake and exposed to tobacco smoke may have the high odds of hypertension. More restrictions on smoking as well as Mg supplementation in the prevention and treatment of hypertension among children and adolescents might be justified.

Validity and reproducibility of food group intakes in a self-administered food frequency questionnaire for genomic and omics research: the Tohoku Medical Megabank Project.

The Tohoku Medical Megabank Project (TMM) was established to realize personalized healthcare and medicine using genomic and omics data. This study evaluated the validity and reproducibility of food group intakes derived from a self-administered food frequency questionnaire (TMM-FFQ) that included the response option "constitutionally unable to eat/drink it" among community-dwelling Japanese adults. Participants comprised 89 men and 124 women aged ≥20 years from Miyagi Prefecture. Participants completed weighed food records (WFRs) for 3 consecutive days per season as reference intake and FFQs in 2019 (FFQ1) and 2021 (FFQ3). Spearman's rank correlation coefficients (CCs) were calculated for correlations between food group intakes estimated from the 12-day WFR and FFQ3 (validity), and for correlations between those estimated from the FFQ1 and FFQ3 (reproducibility). Cross-classification according to quintiles using FFQ and WFR data was also performed. The percentage of participants who chose the "constitutionally unable to eat/drink it" option was non-negligible for some food groups. In the validity analysis, CCs were >0.40 for many food groups; the median across 21 food groups was 0.49 in men and 0.45 in women. The median percentages of cross-classification into exact plus adjacent quintiles were 73.0% in men and 66.9% in women. In the reproducibility analysis, CCs were >0.50 for many food groups; the median across 21 food groups was 0.60 in men and 0.51 in women. The validity of the TMM-FFQ compared with 12-day WFR and the reproducibility of the TMM-FFQ were reasonable for food groups in the TMM cohort studies.

Heavy metal contamination (Cu, Pb, and Cd) of washed and unwashed roadside blackberries (Rubus fruticose L.).

Foraging provides a multitude of individual, social, and environmental benefits. With green spaces decreasing in the United Kingdom, there is an opportunity for roadside verges to become valuable foraging resources; however, there is public concern over the safety of roadside forage. Human ingestion of heavy metal contaminants, such as copper (Cu), lead (Pb), and cadmium (Cd), originating from traffic activity, induces toxic effects in the body. Therefore, maximum Cu, Pb, and Cd guideline limits for human consumption in small fruits were established. However, studies of heavy metal concentrations in roadside forage and the effects of surface washing on concentrations are limited. This study examined Cu, Pb, and Cd in washed and unwashed wild blackberries (Rubus fruticose L.) along a main road in Kent, UK, and compares the values with maximum guideline limits. In all 44 samples, Cu, Pb and Cd concentrations were well below the maximum guideline limit or daily reference intake (RI) value. Cu and Pb concentrations were below the maximum daily intake in every sample if foragers eat one portion (80 g) of berries a day, but consuming a larger quantity of berries per day (e.g., 1 kg) could lead to an intake above the guideline limit for Cu (1 mg) and Pb (0.1 mg), but not Cd (0.03 mg). Washing did not significantly reduce the concentrations of Cu (p = 0.174) or Cd (p = 0.752) in blackberries, but did significantly reduce the Pb concentration (p < 0.001). However, Pb concentration was below maximum guideline limits for every sample regardless of washing treatment. Thus, wild blackberries collected from the roadside were suitable for human consumption, although the findings are not representative of all foraged berries or road networks.

Dietary supplements increase the risk of excessive micronutrient intakes in Danish children

PurposeDietary supplement use is common in Northern Europe. Many dietary supplements contain 100% of nutrient reference values (NRV) of micronutrients. This study investigates the contribution of dietary supplements to micronutrient intake, the prevalence of excess intake of micronutrients, and parental characteristics of dietary supplement use in Danish children.MethodsData on 499 4–10-year-old children from the Danish National Survey of Diet and Physical Activity 2011–2013 were analysed using non-parametric statistics to compare micronutrient intake from the diet and dietary supplements to the reference intake (RI), and to the tolerable Upper Intake Level (UL) for users and non-users of dietary supplements. Furthermore, characteristics of the parents of users and non-users of dietary supplements were examined by logistic regression analysis.ResultsSixty-four percent of the children were dietary supplement users. Multivitamin-mineral supplements were the most frequently used type of supplement (60%). Children of never-smokers were more likely to use supplements than children of smokers. Users had significantly higher total intakes of 15 micronutrients compared to non-users. Intakes of vitamin A, zinc, and iodine from the diet alone exceeded ULs in 12–30% of the children. Use of dietary supplements gave rise to 21–73% of children in exceedance of the aforementioned three ULs as well as the UL for iron (6–45%).ConclusionDietary supplement use was common among 4–10-year-old Danish children and resulted in a considerable proportion of users exceeding the ULs for vitamin A, zinc, iodine, and iron. The long-term health consequences of exceeding these ULs for children are unknown.

The ability of five different front-of-pack labels to assist Australian consumers to identify healthy versus unhealthy foods

ObjectiveThe aim of this study was to assess the relative ability of different interpretive front-of-pack food labels to alert consumers to both healthier and unhealthier options to inform their food choices. MethodsOne thousand Australians completed an online experiment where they rated the nutritional quality of sets of fictional products pre- and post-randomisation to one of five front-of-pack labels: Health Star Rating, Multiple Traffic Lights, Nutri-Score, Reference Intakes and Warning Label. Two sample z-tests were used to assess the ability of each label to facilitate the correct identification of the least and most healthy product options. ResultsThe Nutri-Score was superior in assisting respondents to identify both the healthiest and unhealthiest options. The Health Star Rating ranked second for both outcomes, followed by the Multiple Traffic Lights. ConclusionsResults reinforce the role of interpretive front-of-pack labels in assisting consumers to understand the nutritional quality of food products and suggest spectrum labels may provide superior utility in assisting consumers to identify both the most and least nutritious products from among available product options. Implications for public healthThe strongest performance of a highly interpretive front-of-pack label (Nutri-Score) featuring colour in a summary indicator suggests potential strategies for enhancing the performance of the Health Star Rating.

Front-of-pack labelling of food products: international practices and perspectives

Introduction. A prerequisite for the deve­lopment of the food market is to provide con­sumers with accessible and necessary informa­tion about properties of food products. Food products labeling on the front of the package is aimed at facilitating consumers’ understanding of information about their usefulness. Problem. A wide range of symbols, schemes and formats have been developed which would provide information about the properties of food products to the consumer in the most convenient and accessible form. However, it is important to analyze the existing options and the effecti­veness of this method of informing consumers about the usefulness of food products. The aim of the work is to analyze different approaches to food products labeling on the front of the package in terms of their informativeness and usefulness for consumers. Methods. The methods of comparative ana­lysis and synthesis, selection and generalization, legislative and regulatory documents were used. Results. Many front-of-pack labeling sys­tems are known today, including Multiple Traffic Lights, Reference Intakes, Health Star Rating system, Nutri-Score, etc. Each of these systems has its own peculiarities regarding the content and way of presenting information about the components of the product, in terms of their use­fulness for the human body and the presence / absence of components that may have a negative impact on health. However, the current labeling systems make it possible to compare food products without taking into account other aspects of health im­pact (degree of processing, added additives that make them unhealthy), which does not allow to provide a complete profile of the health benefits of the food product. Conclusions. The analysis of different front-of-pack nutrition labels systems proved that thanks to such information, consumers have the opportunity to choose more healthy food products. The adoption and implementation of a single label on the front of the package can be useful for consumers and reduce the number of cases associated with the negative impact of food products on health.

The development of wearable technologies and their potential for measuring nutrient intake: Towards precision nutrition.

Appropriate food intake and nutritional status are crucial for the maintenance of health and disease prevention. Conventional dietary assessment is mainly based on comparisons of nutrient intakes with reference intakes, failing to meet the needs of personalised nutritional guidance based on individual nutritional status. Given their capability of providing insights into health information non-invasively in real time, wearable technologies offer great opportunities for nutrition monitoring. Nutrient metabolic profiles can be monitored immediately and continuously which could potentially offer the possibility for the tracking and guiding of nutrient intake. Here, we review and highlight the recent advances in wearable sensors from the perspective of sensing technologies for nutrient detection in biofluids. The integration of biosensors with wearable devices serves as an ideal platform for the analysis of biofluids including sweat, saliva and tears. The wearable sensing systems applied to the analysis of typical nutrients and important metabolites are demonstrated in terms of carbohydrates, proteins, lipids, vitamins, minerals and others. Taking advantage of their high flexibility and lightweight, wearable sensors have been widely developed for the in situ quantitative detection of metabolic biomarkers. The technical principles, detection methods and applications are summarised. The challenges and future perspectives for wearable nutrition monitoring devices are discussed including the need to better determine relationships among nutrient metabolic profile, nutrient intake and food intake. With the development of materials, sensing techniques and manufacturing processes, wearable technologies are paving the way towards personalised precision nutrition, although there is still a long way to go before they can be utilised for practical clinical applications. Joint research efforts between nutrition scientists, doctors, engineers and sensor researchers are essential to further accelerate the realisation of reliable and practical wearable nutrition monitoring platforms.

An 18-country analysis of the effectiveness of five front-of-pack nutrition labels

Various front-of-pack food labels (FoPLs) are being introduced across the world, and discussion continues about the most effective label formats to improve consumers’ (i) understanding of the relative healthiness of alternative products and (ii) product choices. Of increasing interest is the relative ability of different types of labels to steer consumers away from unhealthy options (aversion) versus steer them towards healthier options (attraction). The aim of this study was to assess aversion and attraction outcomes for five FoPLs (Health Star Rating, Multiple Traffic Lights, Nutri-Score, Reference Intakes, and Warning Label) across 18 countries (n = 18393). Descriptive analyses assessed improvements in consumer understanding and choice outcomes for each label across three different types of food products. Binary logistic regressions were used to compare the relative ability of the labels to improve respondents’ understanding of product healthiness and their product choices, using the industry-developed Reference Intakes as the comparator. Aversion and attraction effects were assessed for each label/food type combination. Across the total sample, the Nutri-Score performed best in terms of both attraction and aversion results for understanding and simulated choice outcomes, followed by the Multiple Traffic Lights. The Reference Intakes exhibited the weakest performance overall, with the Warning Label and Health Star Rating falling in between. The most effective FoPLs featured a colour-coded spectrum design. The results indicate that front-of-pack labels that are effective in guiding consumers towards healthier food products can also be effective in steering them away from unhealthy options.

Health Literacy and Its Associations with Understanding and Perception of Front-of-Package Nutrition Labels among Higher Education Students

(1) Background: Nutrition labels on the front of food packages have increasingly become the focus of research. However, too few studies have placed special emphasis on nutritionally at-risk subpopulations, such as young adults or those with low literacy/numeracy skills. The present study aimed to assess both the perception and objective understanding of three front-of-package labeling (FOPL) formats currently in use on the Belgian market, i.e., the Nutri-Score, Reference Intakes, and Multiple Traffic Lights, among students of varying health literacy (HL) levels. (2) Methods: A web-based survey was carried out among 2295 students of tertiary education in the province of Liège, Belgium. The questionnaire included questions related to general characteristics, objective understanding, and perception in response to the assigned FOPL format and level of HL. (3) Results: With respect to objective understanding, the Nutri-Score outperformed all other labels across all HL levels, and it was similarly understood in students of varying HL levels. Several students’ characteristics appeared to be associated with each cluster of perception, with the Nutri-Score cluster having the highest percentages of disadvantaged students, i.e., those with inadequate HL, from non-university institutions, with low self-estimated nutrition knowledge, and with low self-estimated diet quality. (4) Conclusion: Overall, the findings supported the Nutri-Score as particularly effective in guiding students in their food choices. Of particular importance is the fact that the summarized and graded color-coded nutritional label would be a useful strategy for those disadvantaged by limited HL.

Polish Consumers' Understanding of Different Front-of-Package Food Labels: A Randomized Experiment.

Dietary practices are a key behavioral factor in chronic disease prevention; one strategy for improving such practices population-wise involves front-of-package labels (FoPL). This online randomized study, conducted in a quota-based sample of 1159 Polish adults (mean age = 40.9 ± 15.4 years), assessed the objective understanding of five FoPL: Health Star Rating, Multiple Traffic Lights, NutriScore, Reference Intakes (RI) and Warning Label. Objective understanding was evaluated by comparing results of two nutritional quality ranking tasks (without/with FoPL) using three food categories (breakfast cereals, cakes, pizza). Associations between FoPL exposure and objective understanding were assessed via multivariable ordinal logistic regression. Compared to RI and across food categories, significant improvement in objective understanding was seen for NutriScore (OR = 2.02; 95% CI: 1.41–2.91) and Warning Label (OR = 1.61; 95% CI: 1.12–2.32). In age-stratified analyses, significant improvement in objective understanding compared to RI emerged mainly among adults aged 18–30 years randomized to NutriScore (all food categories: OR = 3.88; 95% CI: 2.04–7.36; cakes: OR = 6.88; 95% CI: 3.05–15.51). Relative to RI, NutriScore was associated with some improvement in objective understanding of FoPL across and within food categories, especially among young adults. These findings contribute to the ongoing debate about an EU-wide FoPL model.

Dietary patterns of Polish seniors in retirees' households.

About 7 million people in Poland receive pensions. The amount of benefits paid to pensioners is reflected in the income at their households and expenses, including food expenses. The aim of the study was to evaluate the dietary patterns of Polish seniors in the retirees` households on the basis of an analysis of food consumption and energy and nutrient intake. Food consumption evaluation was based on household budget survey conducted by Statistics Poland in 2019 throughout the whole country. Energy and nutrient intake were calculated using the conversion factors. The consumption of unprocessed red meat in retirees' households was 1.83 kg/person/month, meat products - 2.90 kg and kitchen salt - 0.24 kg. 6.52 kg of vegetables and 5.99 kg of fruit were consumed per person per month. The mean energy intake in members of these households was 2387 kcal/day. The proportion of energy from fat was high - 36.6%. 14.2% of energy was derived from protein and 49.6% from digestible carbohydrates. The share of animal fat (55.0 g) was higher than vegetable fat (43.7 g). It was associated with a high percentage of energy from saturated fatty acids - 13.4%. The content of polyunsaturated fatty acids was less than half of the saturated fatty acids. Calcium and vitamin D intake was low (658 mg and 3.8 μg respectively). Red meat, processed meat and salt consumption by seniors was too high in relation to the nutritional recommendations. Vegetables and fruit were consumed in amounts that are recommended. Seniors diet was improperly balanced, e.g. due to the high percentage of energy from fat, including saturated fatty acids. However, the intake of polyunsaturated fatty acids was low. Calcium and vitamin D intake was lower than Reference Intakes.

Objective understanding of five front-of-pack labels among consumers in Nelson Mandela Bay, South Africa

Objective: This study aimed to assess the objective understanding of five front-of-pack label formats, namely the Reference Intake, Multiple Traffic Light label, Nutri-Score, health endorsement logo and warning label, among consumers in Nelson Mandela Bay, South Africa. Design: This was a cross-sectional, exploratory study. Setting: Interviewer-administered surveys were conducted at 12 randomly selected food retail outlets in an urban setting. Subjects: A total of 359 adult participants were included in this study. Outcome measures: Objective understanding was measured by asking participants to rank food products according to their nutritional quality, using the displayed front-of-pack label. Results: The type of front-of-pack label significantly influenced ranking ability (p < 0.00001). All the evaluative front-of-pack labels significantly improved the participants’ ability to identify healthier food products compared with the no-label control. The reductive Reference Intake, however, showed no significant impact on consumer understanding. Conclusion: Evaluative front-of-pack labels significantly improved the participants’ ability to identify healthier food products, when compared with the Reference Intake and no-label control. Future research should test the objective understanding of culturally diverse groups in South Africa, particularly among rural populations.

Evaluation of Dietary Intake and Food Insecurity: A Case Study on Selected Households from Lahore,Pakistan

Background: Food insecurity consistently challenges middle-income countries, including Pakistan. The aim of this study was to evaluate the dietary food intake of the households in the selected location through a semi-structured questionnaire. Methods: A cross sectional study was carried out among 500 households comprised 2094 participants to investigate dietary intake and status of food insecurity. Furthermore, socio-demographic and weekly dietary food intake was collected through a semi-structured questionnaire in 2019. Those households who assent to participate were included in the study. Results: Mean household size was 5.80±2.05 comprised 49.27% male and 50.61% female. Six food types were commonly consumed in the study population. Among these foods (g/capita/day) starch remained at the top 734.43 followed by fruits 256.02 and vegetables 89.77. These data highlighted limited dietary diversity and reduced dietary intake. The energy intake (per capita/day) from the food basket, contribution of the starch was the highest 32.37% versus protein 14.43%, milk 14.08%, vegetables 1.31%, and fruit 7.79% with an overall calories intake 81.08% from all food groups except tea. Finally, of the 500 households, 42.4% people were below the poverty line, 41.8% people at the poverty line, and 15.8% people were above the poverty line. Conclusion: The results showed that dietary intake of the participants was below the reference intake, demonstrating food insecurity and unbalanced diet.

Dietary intake of protein and fat of 12- to 36-month-old children in a Dutch Total Diet Study

PurposeThis study attempted gaining insight into the intake of protein and fat of 12- to 36-month-old children in the Netherlands.MethodsIn 2017, a Total Diet Study (TDS) was carried out in the Netherlands including following three age groups: 12–17-, 18–23- and 24- to 36-month-old children. Protein and fat concentrations of 164 composite samples were analysed and combined with the consumption data from the Dutch National Food Consumption Survey 2012–2016 (DNFCS).ResultsMedian protein intake of the 12- to 35-month-old Dutch children based on the TDS was 35 g/day with main contributions from the food subgroups “milk and milk-based beverages”, “beef” and “yoghurts and desserts”. Median fat intake was 34 g/day with main contributions from the food subgroups “margarines”, “cheeses” and “milk and milk-based beverages”. For the youngest age group (12- to 18-month-old children), (ready to drink) follow-on formula was one of the main contributors to the fat intake.ConclusionCompared to the EFSA reference values, protein intake of the Dutch 12- to 36-month-old children is high, whereas fat intake follows the reference intake. A TDS is a suitable instrument to estimate macronutrient intakes.

Comparison of appropriateness of Nutri-Score and other front-of-pack nutrition labels across a group of Moroccan consumers: awareness, understanding and food choices

BackgroundThe front of pack nutrition label Nutri-Score, intended to help consumers orient their choices towards foods that are more favorable to health, was developed in France and applied in several European countries. Consideration is underway for its use in Morocco. This study aims to assess Moroccan consumers’ perception and objective understanding of Nutri-Score and 4 other nutritional information labels (Health Star Rating, Health warning, Reference Intakes and Multiple Trafic Light) and their impact on purchase intentions.Methods814 participants were asked to choose among 3 food classes (yoghurts, biscuits and cold cuts), which ones they would prefer to buy among three products with different nutritional profiles and then to rank them according to their nutritional quality. Participants first performed these tasks without a visible nutritional label, and then, after being randomized to one of five labels tested, with the nutritional label visible on front of packs. Next, the full set of tested labels was presented to the participants who were asked a series of questions regarding their preferences, the attractiveness of the labels, their perceptions, intention to use and the trustworthiness placed in the labels.ResultsCompared to the Reference Intake, the Nutri-Score (OR = 2.48 [1.53–4.05], p < 0.0001), was associated with the highest improvement in the ability to correctly classify foods based on their nutritional quality. The percentage of participants who improved their food choice was higher than those who worsened it for all the labels. For yogurts and cookies, the most significant improvements were observed for the Nutri-Score and the Reference Intakes: Concerning the perception of labels, the Nutri-Score is the label that received the highest number of positive responses, whether concerning the ease of being spotted (82.2%), of being understood (74%), and to provide rapid information (68.8%). The Nutri-Score was ranked as the preferred label by 64.9% of the participants.ConclusionThe Nutri-Score appears to be the most effective nutritional information system to inform consumers about the nutritional quality of foods in Morocco, where it could constitute a useful tool to help consumers in their food choices in situations of purchase.

An assessment of nutrition information on front of pack labels and healthiness of foods in the United Kingdom retail market

BackgroundFront of pack nutrition labelling is part of United Kingdom government’s programme of activities aiming to tackle diet-related diseases. There are several front of pack labelling formats available and they differ in the information they deliver. This study assessed the frequency of usage of front of pack food labelling systems on food products in the United Kingdom grocery market. It also measured the healthiness of some foods in the online market by categorising them according to their nutrient contents.MethodsFive hundred food products in five categories [(1) cereals and cereal products, (2) dairy products, (3) beverages, (4) packaged meats and meat products, and (5) pre-packaged fruits and vegetables] from three main United Kingdom retail websites were investigated. A simple random sampling method was used for product selection according to the categories on the retailers’ websites. The healthiness of foods was also assessed by categorising them into ‘healthier’, ‘moderately healthy’ and ‘least healthy’ based on fat, saturated fat, salt and sugar contents.ResultsThe total number of label types assessed comprises 19.6% of Guideline Daily Amounts or Reference Intakes and 43.8% had a combination of Traffic Light and Reference Intakes (hybrid label). Slightly over a quarter (27.4%) of products included nutritional information in a grid or table, 3.4% of the foods had two of any of the following: Health Logo, Reference Intakes and Traffic Light labels, and 5.8% did not have any Reference Intakes, Traffic Light, Health Logo or Hybrid label. Most of the foods assessed were manufactured in the United Kingdom with only 30.8% imported from 32 countries across four continents.ConclusionsTraffic Light and Guideline Daily Amounts were the most used front of pack labelling formats on the assessed food product. A higher number of assessed products belonged to the “moderately healthy” and “healthier” categories than the “least healthy”. The imported foods that were found in the United Kingdom retail market showed that food choices could be made from the diverse food types.

Dietary Intake Assessment of Pre-Packed Graviera Cheese in Greece and Nutritional Characterization Using the Nutri-Score Front of Pack Label Scheme.

Gravieras are ‘gruyere’ type hard cheeses with a variety of different products and the second highest consumption in Greece. In this study, we present a dietary intake assessment and a nutritional characterization of pre-packed graviera products sold in the Greek market using Nutri-Score Front of Pack Label (FoPL). The nutrient contents of 92 pre-packed graviera products were combined with daily individual consumption data extracted from the Hellenic National Nutrition Health Survey (n = 93), attempting to evaluate the contribution of graviera’s consumption to the Greek diet. The analysis of nutrients’ intake as a Reference Intake (RI) percentage ranked saturated fat first on the nutrients’ intake list, with RI percentage ranging from 36.1 to 109.2% for the 95th percentile of consumption. The respective % RI for energy, total fat, carbohydrates, sugars, proteins and salt ranged from 12.7–20.7%, 21.6–50.4%, 0–3.1%, 0–6.1%, 37–57.1% and 6.3–42%. Nutri-Score classified 1% of the products to C—light orange class, 62% to D—orange and 37% to E—dark orange, while no products were classified to A—dark green or B—green classes. The comparison between the Nutri-Score classification and the nutrients’ intake assessment, also separately conducted within the classes, showed a higher salt intake after the consumption of products classified as D—orange and E—dark orange.
