Estimated health benefits, costs, and cost-effectiveness of implementing WHO's sodium benchmarks for packaged foods in India: a modelling study.

Excess dietary sodium intake has been associated with death and disability. WHO has released global sodium benchmarks for packaged foods to support countries to reduce population sodium intake. This study aimed to assess the potential health effect, costs, and cost effectiveness of implementing these WHO sodium benchmarks in India. We used a multiple cohort, proportional multistate, life table (Markov) model to estimate the health gains and cost effectiveness for adults if sodium content in packaged foods complied with the WHO benchmarks compared to the status quo. We used India-specific dietary surveys, food composition tables, foods sales data, and sodium content data from packaged food labels to estimate sodium intake before and after the intervention. Data on blood pressure, cardiovascular disease, and chronic kidney disease burden were obtained from the Global Burden of Diseases, Injuries, and Risk Factors study, and the effect of sodium reduction on blood pressure and disease risk was modelled on the basis of meta-analyses of randomised trials and cohort studies. Intervention and health-care costs were used to estimate net costs, and calculate the incremental cost per health-adjusted life-year (HALY) gained. Costs and HALYs were discounted at 3%. In the first 10 years, compliance with the WHO sodium benchmarks was estimated to avert a mean of 0·3 (95% uncertainty interval [UI] 0·2-0·5) million deaths from cardiovascular diseases and chronic kidney disease, a mean of 1·7 (95% UI 1·0-2·4) million incident cardiovascular disease events, and 0·7 (0·4-1·0) million new chronic kidney disease cases, compared with current practice. Over 10 years, the intervention was projected to be cost saving (100·0% probability), generating 1·0 (0·6 to 1·4) billion HALYs and US$0·8 (95% UI 0·3 to 1·4) million in cost savings. Over the population lifetime, the intervention could prevent 4·2 (2·4-6·0) million deaths from cardiovascular diseases and chronic kidney disease, 14·0 (8·2-20·1) million incident cardiovascular disease events, and 4·8 (2·8-6·8) new chronic kidney disease cases, with an 84·2% probability of being cost-saving and 100·0% probability of being cost-effective. Our modelling data suggest a high potential for compliance with WHO sodium benchmarks for packaged food being associated with substantial health gains and cost savings, making a strong case for India to mandate the implementation of the WHO sodium benchmarks, particularly as packaged food consumption continues to rise.

Evaluating the application of front-of-package labelling regulations to menu labelling in the Canadian restaurant sector using Menu Food Label Information and Price (Menu-FLIP) 2020 data.

To evaluate the application of front-of-package (FOP) labelling regulations to menu labelling in the Canadian restaurant sector by assessing the proportion of menu items that would be required to display the 'high-in' FOP symbol if the policy were extended to the restaurant sector. Nutrition information of 18,760 menu items were collected from 141 chain restaurants in Canada. Menu items were evaluated using the mandatory FOP labelling regulations promulgated in Canada Gazette II by Health Canada in July of 2022. Chain restaurants with ≥20 establishments in Canada. Canadian chain restaurant menu items including beverages, desserts, entrées, sides, and starters. Overall, 77% of menu items in the Canadian restaurant sector would display a 'high-in' FOP symbol. Among these menu items, 43% would display 'high-in' one nutrient, 54% would display 'high-in' two, and 3% would display 'high-in' all three nutrients-of-concern. By nutrient, 52% were 'high-in' sodium, and 24% and 47% were 'high-in' total sugars and saturated fat, respectively. Given the poor nutritional quality of restaurant foods, the current regulations, if applied to restaurant foods, would result in most menu items displaying a FOP symbol. Therefore, expanding the Canadian FOP labelling regulations to the restaurant sector can be key to ensuring a healthy food environment for Canadians. Furthermore, menu labelling along with other multi-faceted approaches such as reformulation targets are necessary to improve the dietary intake of Canadians from restaurant foods.

Child-targeted foods in the Portuguese market 2024: Nutritional characteristics and claims

Abstract Background Excessive consumption of high-energy products with high saturated fats, sugars, and salt contents, contribute to the prevalence of overweight, obesity and other related diseases in Portugal, especially among children. Children represent a vulnerable group whose food choices are significantly influenced by advertisements and marketing methods that often promote highly palatable and less healthy foods. This study aimed to assess the nutritional characteristics of visually appealing products targeted at children in Portugal and analyse nutritional, health, and other mentions and claims, as well as icons present in the package. The goal is to contribute to the promotion of healthier food choices and inform public health policies. Methods Nutritional information and mentions/claims from child-targeted foods, featuring labels with cartoons and other appealing images, were collect. These were compared with the reference values (RV) of Integrated Strategy for the Promotion of Healthy Eating (EIPAS) and of Directorate-General of Health Label Decoder (RVLD), as well as the limit values (LV) defined by a Portuguese law related to restrictions on food advertising aimed at children. Results 247 products from six categories were monitored. Only 1.2% met the EIPAS RV for sugar and salt evaluated together, while 10.1% complied with the law LV. According to the RVLD, 19.0%, 26.3%, 49.4%, and 0.4% of the products presented high levels of fat, saturates, sugars, and salt, respectively. The majority of the products (68.0%) had one or more types of mentions/claims, predominantly nutritional (64.3%) and all featured one or more icons, with 10.5% being licensed. Conclusions The majority of these pre-packed child-target foods do not have a healthy nutrient profile. In this context, public health actions, namely legislative measures to further regulate food marketing and labeling elements aimed at children along with literacy and product reformulation initiatives are essential. Key messages • The child-targeted food products in the Portuguese market present inadequate nutritional profiles. • Public health actions are needed to promote healthier food choices and protect children from foodborne non-communicable diseases.

Exploring knowledge, attitudes and practices towards sustainable food aid programmes across Europe

Abstract Background Food insecurity has increased following the COVID-19 pandemic and the Ukraine conflict. In some EU high-income countries, more than 70% of food aid users experience food insecurity, highlighting the need for food aid programmes to provide good quality and sustainable services and maximise the social inclusion of food aid users. The aim of this study was to identify areas that can promote sustainability in food aid programmes. Methods Knowledge, attitudes and practices towards sustainable food aid were assessed via a quantitative questionnaire. Socio-demographic data were also collected. The survey was translated and disseminated online across 5 EU countries (Austria, Cyprus, Greece, Poland, Portugal), targeting staff and volunteers involved in food aid programmes (20 per country, total N = 100). Descriptive statistics were used for data analysis. Results Most participants were female (68%), 18-49 years old (87%) and occupied in a NGO (89%) as employee (55%). The mean total knowledge score was 11.8 out of 19 (SD 3.2) with low knowledge (% of correct answers) on household food waste (18%) and environmental impact of cooking appliances (29%). In all countries (except Austria) more than 70% of participants agreed that they can apply sustainability through their work; however, more than 50% agreed that sustainability is not always feasible in food aid programmes. Food loss/waste, access to local food and the economic crisis were the main parameters reported to impact sustainability in food aid (≥70% of N). The most frequently applied practices were storing food according to expiration date, monitoring quantities in food distribution, considering beneficiaries’ needs and reading food labels. The least frequently applied practices were composting food leftovers and using energy-efficient methods to distribute food. Conclusions Sustainability is considered important; however, more effort is needed to promote and embed sustainability parameters in food aid programmes. Key messages • Sustainability is considered important in food aid programmes; however, more effort is needed to promote and embed sustainability parameters in practice. • Identifying sustainability areas in food aid programmes can lead to successful educational and training initiatives.

Declaration of free sugars from fruits on food labels: a scoping review

PurposeThe World Health Organization recommends limiting the intake of free sugars, which can be added to packaged foods and may appear on labels under different terms. The aim of this research was to analyse the evidence related to the declaration of free sugars from fruits on packaged food labels.Design/methodology/approachA scoping review was conducted following the recommendations of the Joanna Briggs Institute (JBI).FindingsTen eligible studies, conducted in seven countries, were included in this review. The percentage of packaged foods in which free sugars were identified ranged from 52.5 to 86.5%. In three studies, terms related to sugars were identified inductively by reading the entire ingredient list, whereas in the other studies sugars were identified by searching for a list of predefined terms. Studies differed in the definition of sugars and the terms used to identify them. Nine studies included fruit sugars within the terms used to identify free sugars. However, they lacked consistency in the types of fruit sugars considered and did not discuss their agreement with the adopted definitions of sugars.Originality/valueAs far as can be ascertained, this is the first review that addresses the declaration of free sugars from fruits on packaged food labels. Overall, there is a scarcity of literature focused on identifying and discussing the range of free sugars from fruits declared on food labels.

Dietary Habits of Young Poles and Their Selected Determinants: A Review and Implications for Public Health.

This study investigates the dietary patterns, health behaviors, and related determinants among young people in Poland, amid increasing lifestyle-related health concerns like obesity and poor nutrition. Understanding the factors influencing these behaviors is crucial for crafting effective public health strategies. The objective was to analyze young Poles' eating habits, their perceptions of health, and the role of various determinants in shaping these behaviors. A survey was conducted among a representative sample of young Poles, gathering data on eating habits, health perceptions, and lifestyle choices. The survey focused on the respondents' understanding of healthy eating, sources of nutrition knowledge, and the influence of family, social media, and public health campaigns. Data were analyzed using descriptive statistics, and correlations between health behaviors and socio-demographic factors were examined. The study revealed that 88% of young respondents prioritize health, with 73% acknowledging a link between nutrition and health. While most participants accurately described healthy eating and reported adherence to dietary guidelines, 43% engaged in emotional eating, which often led to compulsive behaviors associated with obesity. Social media, internet articles, and family were primary sources of nutrition knowledge. Despite their knowledge, fruit and vegetable consumption was below recommended levels, and physical activity levels were insufficient in nearly half of the respondents. Only 36% regularly read food labels, with many choosing products containing additives. Appearance-related stress was prevalent among 52% of respondents, while sleep deficits and lack of sufficient physical activity were common. The findings suggest that while young Poles possess a high level of awareness regarding healthy eating, gaps remain in the application of this knowledge, particularly concerning emotional eating and inadequate fruit and vegetable consumption. Public health campaigns should be more effectively targeted to address these gaps and promote sustainable health behaviors from early childhood. Addressing emotional eating, enhancing physical activity, and improving nutrition education through effective channels like social media are key to improving public health outcomes.

Simultaneous analysis of certain tree-nut allergens in cookies by LC-MS/MS

In this study, four tree-nut allergens were identified using liquid chromatography-mass spectrometry (LC-MS/MS) with a reverse-phase XSelect HSS C18 SB column (100 mm x 2.1 mm, 3.5 µm) and corresponding guard column. The gradient solvent program employed 0.1% formic acid in water and 0.1% formic acid in acetonitrile, with a flow rate of 0.5 mL/min, a positive ion electrospray ionization (ESI+) source, and a multiple reaction monitoring (MRM) mode. The method was validated following the guidelines of AOAC International. Results showed that the method had good specificity, with calibration curves constructed in the concentration ranges of 30.5 - 1220 µg/g for almonds, 102 - 4080 µg/g for cashews, 128 - 5120 µg/g for hazelnuts, and 122 - 4880 µg/g for pistachios. Limits of detection were 9 µg/g for almonds, 30.6 µg/g for cashews, 38.4 µg/g for hazelnuts, and 36.6 µg/g for pistachios, while limits of quantification were 30.5 µg/g for almonds, 102 µg/g for cashews, 128 µg/g for hazelnuts, and 122 µg/g for pistachios. The repeatability and accuracy of the method met AOAC requirements. The method was used to analyze the content of four groups of nut allergens (almond, cashew, hazelnut, and pistachio) in ten cookie samples from the Hanoi area. Results indicated that three samples contained undeclared allergens on the food labels.

Computational model for policy simulation and prediction of the regulatory impact of front-of-package food labels

Non-communicable diseases (NCDs), a significant cause of global mortality, necessitate targeted policy measures to reduce exposure to risk factors, particularly nutrition-related ones. Front-of-pack food labeling aims to shape consumer behavior and decrease exposure to nutritional risk factors. There are various forms of this policy, including traffic light (TL), nutrient profile model (NPM), and reference value (RV) labels. Mathematical models incorporating experimental and dose–response data support determining the most effective form. When selecting a modeling method, it is essential to consider the uncertainty involved in estimating risk factors. This study aims to create a computational model to predict the health and economic impacts of different policy options using an improved version of the Scarborough algorithm, incorporating a validation process to address potential uncertainties. The model shows that NPM was the most effective, reducing the estimated annual mortality rate from 514,247 cases to 447,394 cases (13% reduction). The following labels were TL (11% reduction) and RV (6% reduction). Economically, the RV label affects consumer spending the least, predicting an 8% increase in monthly spending per individual from the baseline. When assessed from both health and economic perspectives, the RV label has emerged as the most advantageous front-of-pack food labeling policy. The proposed model can aid policymakers in evaluating policy alternatives and thus selecting the most advantageous policies based on health and economic outcomes while ensuring the model's accuracy and applicability for the community.

Global Trends and Research Collaborations on Food and Beverages Warning Labels: A Bibliometric Analysis

Background: Non-communicable diseases (NCDs) represent a global health challenge, accounting for 74% of deaths worldwide. One of the recommended interventions to reduce the risk of NCDs is the implementation of warning labels (WLs) on food products to alert consumers about high levels of undesirable nutrients, such as sugar or saturated fats. We aimed to conduct a bibliometric analysis of scientific literature related to WL policies in food and beverages to evaluate global trends and collaborations. Methods: A bibliometric analysis was performed using the Web of Science Core Collection (WoSCC). Articles published between 1998 and 2023 were retrieved using the search terms “warning labels” AND “food” OR “beverage”. Bibliometric indicators, including publication counts, citations, collaborations, and thematic trends, were analyzed using the Bibliometrix package in R and VOSviewer. Results: We included 255 articles on WLs. Scientific production increased markedly from 2018 onwards, with over 30 articles published annually from 2018 to 2023. The most cited article, by Taillie et al., focused on the impact of Chile’s WL policies. The United States had the largest scientific production, followed by Brazil and Chile. Nutrients was the journal with the most publications on this topic. Conclusions: The growth in WL-related research, particularly in Latin America, reflects the increasing implementation of these policies. These results underscore key collaborations and evolving research themes, from food labeling to broader public health impacts, emphasizing the need for continued evaluation of WL effectiveness.

Understanding the Politics of Food Regulation and Public Health: An Analysis of Codex Standard-Setting Processes on Food Labelling

Background: The importance of the international food regulatory system to global health, is often overlooked. There are calls to reform this system to promote healthy and sustainable food systems centred on the Codex Alimentarius Commission (Codex), the United Nation’s (UN’s) standard-setting body. Yet this presents a significant political challenge, given Codex has historically prioritized food safety risks over wider harms to public health, and is dominated by powerful food exporting nations and industry groups with a primary interest in trade expansion. To better understand this challenge, we examine who participates and contests Codex standards, using the development of the new Guidelines on Front-of-pack Nutrition Labelling (FOPNL) as a case study. Methods: The study involved: (i) collecting Codex Committee on Food Labelling (CCFL) documents (2016-2023); (ii) identification, categorization, and enumeration of actors involved in the development of the Guidelines; and (iii) guided by a constructivist framework, analysis of how actors framed and contested key provisions of the Guidelines. Results: Country representation was skewed towards high-income (47.9%). Member state delegations were dominated by non-health ministries (59.8%) and industry actors (16.1%). Industry actors comprised the large majority of observers (84.2%) and civil society actors representing public health interests the least (12.2%). Commercial actors used frames supporting positive FOPNL messages (eg, low in salt) opposing negative ones (eg, "high-in" sugar warnings) and called for product exemptions (eg, sports foods and baby foods). Public health actors used frames supporting simplified FOPNL to reduce consumer confusion, that hold up public health goals, and prevent inappropriate marketing. Conclusion: Participation in the Guidelines development process suggests stronger preferences for trade facilitation and commerce over public health. Ambitions to reform the international food regulatory system may require an examination of who participates and how to address this asymmetrical representation of interests. These results suggest the need to greatly strengthen public health representation at Codex.

Barriers and enablers to salt intake reduction in Australian adults with high blood pressure.

High dietary salt intake is a known risk factor for hypertension. However, Australians continue to consume excessive amounts of salt. The purpose of this study was to identify barriers, enablers and strategies to reduce salt in a sample of Australian adults with hypertension. This was a qualitative study. Participants were asked a set of open-ended questions during focus groups conducted between October 2020 and April 2021. Sessions were recorded and transcribed. Using an inductive approach, the transcript data from the focus groups were thematically analysed. This involved checking accuracy, becoming familiar with the data, coding responses based on questions, identifying themes through common patterns and validating themes by grouping similar questions that represented the data and study aim effectively. Thirty-one adults (55 % females) with high blood pressure participated in the focus group discussions. Participants demonstrated good knowledge of high blood pressure risk factors but lacked an understanding of recommended salt intake levels and sources of hidden salt. Challenges in reducing salt intake included the limited availability of low-salt commercial foods. Participants suggested improved food labelling and the use of technology-based interventions to promote healthier choices. Findings highlight the need for behavioural interventions, policy reforms and collaborations between the government, food industries and health organisations to address high salt intake in the population.

Psychometric properties of the Functional Literacy Questionnaire among Portuguese adolescents.

Robust tools to assess self-reported adolescent functional health literacy are lacking. In Portugal, the only available tool is the Newest Vital Sign for Portuguese adolescents (NVS-PTeen), though presenting modest validity and reliability properties. A new instrument-the Functional Literacy Questionnaire (FLiQ)-was developed, inspired by the NVS-PTeen, but following the European Regulation for food labeling and targeting a balanced assessment of numeracy and verbal comprehension skills. This study aimed to evaluate several psychometric properties of the FLiQ when administered to Portuguese adolescents. We conducted a longitudinal observational study with three phases: (1) Delphi panel with health literacy experts; (2) self-administration of FLiQ and NVS-PTeen to adolescents in 7th to 9th grades; and (3) re-administration of FLiQ four weeks after baseline, to the same group of participants. FLiQ's content validity was excellent, with an Average-Content Validity Index of .95. Overall, 372 adolescents (50.3% girls) aged between 12-17 years (median age: 13) participated in the study. Of these, 150 completed the test-retest assessment. Internal consistency was good (Kuder-Richardson Fornula-20 = .70), as well as test-retest reliability (Intraclass Coefficient Correlation = .82). FLiQ total score was weakly correlated with the school year (rho = .174), and moderately with Portuguese (rho = .348) and Mathematics grades (rho = .333). Factor analysis indicated a two-dimension structure, reflecting numeracy and verbal comprehension skills. Item response theory analysis revealed differences in difficulty and discrimination capacity among items, all with adequate fit values. FLiQ is a valid and reliable tool. It can be used to monitor functional health literacy levels in Portuguese adolescents.

Evaluation of a Workplace Diabetes Prevention Program Delivered via Distance Learning: A Qualitative Study.

Little is known about how distance learning impacts delivery of the National Diabetes Prevention Program (DPP) despite a rapid shift to this platform during the coronavirus disease 2019 (COVID-19) public health emergency. We explored how a workplace DPP, delivered via distance learning, impacted knowledge, motivation, and behavioral skills of participants throughout the program. We conducted repeated qualitative interviews with distance learning participants at baseline, 6 months, and 12 months from September 2020 to July 2022. Three study team members coded interview data using individual responses as the unit of analysis. We used a thematic approach, using the information-motivation-behavioral skills framework, to analyze responses and generate understanding of the program's impact. The 27 individuals who participated in the interviews (89% women, mean age 56 years) reported the distance learning platform was effective in changing their behavior. The program's focus on food logging and setting limits on specific types of caloric intake was perceived as essential. Education on ideal levels of fat and sugar consumption, lessons on how to read food labels, and dissemination of recipes with healthy food substitutions allowed participants to initiate and sustain healthy decision-making. Strategies to increase physical activity, including breaking up exercise throughout the day, made reaching their goals more feasible. Participants reported food logging and weight reporting, as well as group support during sessions, either sustained or increased their motivation to adhere to the program over time. A workplace DPP delivered via distance learning successfully prompted improvements in the knowledge, motivation, and behavioral skills necessary to increase healthy eating and physical activity among participants.

Exploring the influence of different processing conditions on DNA quality of collagen peptides and the feasibility of its raw material traceability

In this work, we have presented a new method for species origin verification of collagen peptides based on DNA techniques. First, we investigate the changes in DNA during the preparation of collagen peptides including the total amount of collagen peptide DNA and the DNA degradation under different processing conditions. Secondly, we discussed the possibility of using polymerase chain reaction (PCR) for follow-up detection of collagen peptides. The results showed that the total amount of DNA decreased as the treatment intensity increased. The size of the cleaved fragments of DNA are mainly concentrated between 200 and 500 bp. On this basis, the combined PCR results finally determined that trace collagen peptide DNA can be effectively amplified with amplicons of about 300 bp to complete the verification of the species origin of collagen peptide. This study provides a new strategy for determining the authenticity of food labels for bovine collagen peptides.

Assessment of foods for infants and toddlers in Australia against the World Health Organization's Nutrient and Promotion Profile Model for food products for infants and young children.

Global public health agencies have recommended stronger regulation of food marketing to protect children's diets. This study assessed commercial foods for infants and toddlers available in Australian supermarkets for compliance with the World Health Organization (WHO) Regional Office for Europe's Nutrient and Promotion Profile Model: supporting appropriate promotion of food products for infants and young children 6-36 months in the WHO European Region (NPPM). Dietitians assessed a sample of commercial foods for infants and toddlers against the composition, labelling and promotion requirements of the NPPM. Australia. Commercial foods for infants and toddlers (n 45) available in two major Australian supermarkets, purposely sampled across product categories and brands. Fewer than one quarter (23 %) of the assessed products met all nutrient content requirements of the NPPM. No products met all of the labelling or promotional requirements. All products included at least one promotional marketing claim that was not permitted under the NPPM. The NPPM is useful to assess and monitor the nutritional composition and prevalence of marketing claims on commercial foods for infants and toddlers. Findings of noncompliance with the NPPM recommendations indicate an urgent need for stronger government regulation of the composition, labelling and marketing of commercial foods for infants and toddlers in Australia.

Assessment of Practices on Purchase of Packaged Foods and Utilization Patterns of Food Labels among Adults in Puducherry

Abstract Background: There is an increase in the manufacture and consumption of prepackaged foods as a result of widespread urbanization, long working time, and adaption to a sedentary lifestyle. The majority of these prepackaged foods contain food labels. Food labeling is a community-based strategy that informs customers about a food’s nutritional composition, empowering them to choose healthier foods. To assess the practices on the purchase of packaged foods and utilization patterns of food labels among adults in Puducherry. Material and Methods: A cross-sectional survey in the field practice area of a private medical college at Puducherry was carried out for two months including adults residing for > 6 months in selected villages/wards. A sample size of 460 with a multistage sampling technique was considered. Data collection using a semi-structured questionnaire incorporated into Epi-collect software and was analyzed using SPSS16. Ethical clearance was obtained from Institutional Ethical Committee. Written informed consent was sought from participants. Results: Around 271 (58.91%) and 189 (41.08%) respondents were residing in urban and rural regions, respectively. Purchase of packages was seen in 297 (64.57%) people. Only one-fourth of the subjects had the practice of reading the food labels, with urban residents having a better practice when compared with rural population (P value < 0.05). Conclusion: The study reveals a low level of utilization pattern of food labels among consumers of packaged food products. The findings of this study would be helpful for concerned authorities in creating and improving awareness among consumers and ensuring that their usability is improved.

Exploring Dietary Salt Knowledge, Attitude, and Practices among People of African Descent in the United Kingdom: A Qualitative Study.

Background/Objectives: People of African Descent (PoAD) in the United Kingdom (UK) are at an increased risk of hypertension and cardiovascular disease (CVD), partly due to dietary habits such as high salt intake. This study sought to understand the dietary salt-related knowledge, attitudes, and practises (KAP) of PoAD in the UK, to inform the development of culturally tailored interventions to reduce dietary salt intake in this population. Methods: We collected data on KAP from 21 PoAD across various regions in the UK through online semi-structured interviews and analysed them using reflexive thematic analysis (TA). Results: The age of the participants ranged from 20 to 70 years (43 ± 11). Six overarching themes were identified: (i) the multifaceted roles of salt in culinary practises, (ii) the increased awareness of health risks associated with high salt intake, (iii) the existence of knowledge gaps regarding recommended daily salt intake, (iv) the cultural influences on salt consumption levels, (v) the lack of engagement with food labels, and (vi) a limited awareness of salt reduction initiatives. Conclusions: Our findings highlight the significance of salt in the culture and culinary practises of PoAD. Despite general awareness of the health risks of excessive salt consumption, there was a notable deficiency in knowledge about the recommended salt intake levels as well as minimal engagement with nutritional labelling. These findings underline a need for culturally sensitive health interventions that integrate culinary practises, beliefs, and preferences of PoAD, aiming to effectively reduce salt intake and mitigate associated health risks.

Voluntary versus mandatory food labels, Australia.

To compare uptake of the voluntary Health Star Rating front-of-pack nutrition labelling system with uptake of a mostly mandatory country-of-origin label in Australia over a similar period. We used data on numbers and proportions of products carrying health stars and country-of-origin labelling recorded annually between 2015 and 2023 through surveys of four large Australian food retailers. We determined the proportion of products with health stars and country-of-origin labels for each year by dividing the number of products carrying each label by the total number eligible to carry that label. The uptake of the voluntary Health Star Rating increased steadily between 2014 and 2018, reaching a maximum of 42% (8587/20 286) of products in 2021 before decreasing to 39% (8572/22 147) in 2023. Mandatory country-of-origin labelling uptake rose rapidly and was found on 93% (17 567/18 923) of products in 2023. In categories where country-of-origin labelling was voluntary, uptake by 2023 was 48% (3313/6925). In our 2023 sample of 22 147 products, 11 055 (50%) carried country-of-origin labelling only, 7466 (35%) carried both health star and country-of-origin labelling, 1106 (5%) carried health star labels only and 2520 (11%) carried neither label. The experience with country-of-origin labelling shows that widespread and rapid food labelling change can be achieved when required by law. The Australian government should mandate the Health Star Rating without delay. Australia's experience supports other jurisdictions in implementing mandatory front-of-pack nutrition labelling as well as updates to global guidance to recognize mandatory labelling as best-practice in delivering benefits to consumers.

In-situ electrochemically synthesized “artificial” Gly m TI antibody for soybean allergen quantification in complex foods

Biosensors, especially those designed for detecting food allergens like Gly m TI in soybean, play a crucial role in safeguarding individuals who suffer from adverse food allergies, extending to both individual well-being and broader public health considerations. Furthermore, their integration into food production and monitoring processes aids in compliance with regulatory standards, reducing the incidence of allergen-related recalls and protecting vulnerable populations. Technological advancements in biosensor development, such as increased portability, real-time monitoring capabilities, and user-friendly interfaces, have expanded their practical applications, making them indispensable in various settings, including manufacturing plants, food service establishments, and even at-home use by consumers.For the first time, a biosensor targeting the Gly m TI allergen based on molecularly imprinted polymer (MIP) technology was developed to detect/quantify soybean in complex food matrices and effectively address the detection challenges of complex and processed foods. The Gly m TI-MIP underwent a thorough validation process using anti-Gly m TI IgG raised as a polyclonal response to the trypsin inhibitor. Gly m TI-MIP was successfully tested across a range of food matrices, including tree nuts (e.g., peanuts, walnuts, and hazelnuts) and legumes (e.g., lentils, beans, and lupine), presenting minimal cross-reactivity with lupine and walnut. The innovative approach provided a linear response in the 1 ag mL−1 - 10 μg mL−1 range, with a LOD<1 ag mL−1. Applying the Gly m TI-MIP sensor to complex model foods allowed to detect 0.1 mg kg−1 (0.00001 %) of soybean protein isolate in biscuits, ham, and sausages before and after the respective thermal treatments. The innovative biosensor can significantly improve food safety protocols by addressing the complexities of tracing allergens in processed and unprocessed food products. By ensuring rigorous allergen control, these biosensors may support global food trade compliance with international safety standards, boost consumer confidence, and promote transparency in food labeling, ultimately contributing to a safer food supply chain.
