The prevalence of obesity and diet related non-communicable diseases (NCDs) are rapidly increasing in Africa. Consumption of pre-packaged foods is one of the main drivers of these NCDs. Pre-packaged foods tend to contain high levels of energy, fat, sugar, and salt, which are known risk factors for NCDs. Food labels can guide consumers to make informed healthy food choices. Therefore, it is important to analyze how health-related information is communicated on food labels. In Ghana, there is paucity of evidence on what health-related information is available to consumers of pre-packaged foods. This study describes health-related information on labelled pre-packaged foods sold in local retail shops in Accra. A cross-sectional survey and quantitative content analysis of food label information were employed in this study. Pre-packaged food labels photograph data were sourced from shops and content analyzed to describe their health-related information. Nutrition and health-related information were classified using the International Network for Food and Obesity/Non-Communicable Diseases Research, Monitoring and Action Support (INFORMAS) system. Three hundred and fifty-one (N=351) pre-packaged foods and non-alcoholic beverages were sampled, out of which 2.3% products were unlabelled. Out of 343 labelled products, 92% disclosed ingredient list information and 68.8% had nutrition declaration. Between the two nutrition labelling formats: Back-of-Pack (BOP) and Front of Pack (FOP), BOP was the dominant (87.3%) format. Various types of FOPs were identified however, Guidelines Daily Allowance (GDA) was the most common format. The study found that 18% of labelled pre-packaged foods carried nutrition claim and about 7% had a health claim. Most of the claims were written and the others were a combination of words, numbers, and pictures/symbols. This study has shown a high disclosure of health-related label information on pre-packaged food but information presentations on labels were not consistent. The insight gained from this study shows that the presentation of health-related label information does not meet the current recommendations of Codex and the benchmarks set out by INFORMAS in promoting a healthy food environment.

This study used various nutrient profile models (NPMs) to evaluate the nutritional quality of pre-packaged foods in China to inform future food policy development. Nutrition data for pre-packaged foods were collected through FoodSwitch China in 2017–2020. The analyses included 73,885 pre-packaged foods, including 8236 beverages and 65,649 foods. Processed foods (PFs) and ultra-processed foods (UPFs) accounted for 8222 (11.4%) and 47,003 (63.6%) of all products, respectively. Among the 55,425 PFs and UPFs, the overall proportion of products with an excessive quantity of at least one negative nutrient was 86.0% according to the Chilean NPM (2019), 83.3% for the Pan American Health Organization NPM (PAHO NPM), and 90.6% for the Western Pacific Region NPM for protecting children from food marketing (WPHO NPM), respectively. In all NPMs, 70.4% of PFs and UPFs were identified as containing an excessive quantity of at least one negative nutrient, with higher proportions of UPFs compared to PFs. Food groups exceeding nutrient thresholds in most NPMs included snack foods, meat and meat products, bread and bakery products, non-alcoholic beverages, confectionery, and convenience foods. In conclusion, PFs and UPFs accounted for three-fourths of pre-packaged foods in China, and the majority of PFs and UPFs exceeded the threshold for at least one negative nutrient under all three NPMs. Given the need to prevent obesity and other diet-related chronic diseases, efforts are warranted to improve the healthiness of foods in China through evidence-based food policy.

AbstractObjective:To describe the Na concentration of pre-packaged foods available in Hong Kong.Design:The Na concentrations (mg/100 g or mg/100 ml or per serving) of all pre-packaged foods available for sale in major supermarket chains in Hong Kong were obtained from the 2017 Hong Kong FoodSwitch database. Median and interquartile range (IQR) of Na concentration for different food groups and the proportion of foods and beverages considered low and high Na (<120 mg/100 g or mg/100 ml and >600 mg/100 g or mg/100 ml, respectively) were determined.Setting:Hong Kong.Participants:Not applicable.Results:We analysed 11 518 pre-packaged products. ‘Fruit and vegetables (including table salt)’ had the highest variability in Na concentration ranging from 0 to 39 000 mg/100 g, followed by ‘sauces, dressings, spreads and dips’ ranging from 0 to 34 130. The latter also had the highest median Na concentration (mg/100 g or mg/100 ml) at 1180 (IQR 446–3520), followed by meat and meat products (median 800, IQR 632–1068) and snack foods (median 650, IQR 453–926). Fish and fish products (median 531, 364–791) and meat and meat products (median 444, IQR 351–593) had the highest Na concentration per serving. Overall, 46·7 and 26·7 % of products were low and high in Na, respectively.Conclusions:Our results can serve as a baseline for food supply interventions in Hong Kong. We have identified several food groups as priority areas for reformulation, demonstrating the potential of such initiatives to improve the healthiness of the food supply in Hong Kong.

Background: High salt intake is the main dietary risk factor for hypertension, one of the five leading causes of death, among Jamaicans. A large share of available pre-packaged products are ultra-processed, containing sodium well in excess of recommended healthy thresholds. Policymakers are advocating for reformulations and devising public education strategies to reduce sodium content which requires an understanding of the amount and variety of sodium compounds being used in products. Procedures: This study describes the sodium content of 5,008 pre-packaged products using food label analysis. Products were divided into 15 foods and 4 beverage categories. Descriptive statistics were used to present sodium data. Additionally, a keyword search for the terms “salt” and “sodium” was done to identify the type and variety of sodium-containing ingredients in each product. Findings: Approximately, 44% of products were high in sodium. In addition to salt (sodium chloride), other sources of sodium included 27 sodiumcontaining chemical additives identified from the ingredient listing. Ready-to-heat/eat foods, animal meat products, dry spices, seasoning, spreads and sauces contained the most sodium per serving. There was high variability in mean sodium levels within and across food and beverage categories. Conclusions: Overall, a large share of pre-packaged products in Jamaica are ultra-processed emphasizing the urgency for product reformulations and policies towards healthier levels of sodium.

AbstractObjective:To assess the presence of nutrition declarations and nutritional quality in pre-packaged food products sold in Guatemala.Design:We photographed nutrition labels of pre-packaged foods. We extracted information about declaration of energy, total/saturated/trans-fats, total/added sugars and Na content (critical nutrients). We classified all products according to their degree of processing (NOVA classification) and nutritional quality (PAHO and WHO-Europe nutrient profile models).Setting:Pre-packaged foods for sale in seven supermarkets in Guatemala City.Participants:This study did not involve human subjects.Results:We assessed 3459 pre-packaged foods, including 80 % ultra-processed, 7 % processed and 13 % unprocessed/minimally processed foods or culinary ingredients. Nutritional information was available in 3021 products (87·3 %). Energy content was declared in 87·0 %; total fats in 86·1 %; saturated fats in 81·5 %; trans-fats in 48·9 %; total sugars in 70·3 %; added sugars in 0·5 % and Na/salt in 85·5 % of products. Insufficient nutrient information made impossible to assess nutritional quality in 36·6 and 17·1 % of products with the PAHO and WHO-Europe models, respectively. Using PAHO and WHO nutrient profiles, we found that 66·2 and 50 % of food products did not meet the model’s nutritional criteria.Conclusions:A high proportion of pre-packaged foods with nutritional information available in Guatemalan supermarkets do not meet the nutritional criteria recommended by WHO and PAHO. Furthermore, a high proportion of products did not declare critical nutrients and many did not even provide any nutritional information. National regulations should consider making critical nutrient declarations (including trans-fats and sugars) mandatory for all products.

Purpose The purpose of this paper is to investigate whether the prepackaged foods in Malaysia are able to provide credible nutrition labels for consumers and how many prepackaged foods do not comply with the tolerance limits, regardless of whether the products are sold in Malaysia or exported to overseas even though there are no standardization of tolerance limits. Design/methodology/approach The present study consists of 300 samples (triplicate samples for each product) of core nutrients (energy, fat, carbohydrate and protein), which have been stratified into eight categories, were analysed and the analytical values were compared with the declared values. Compliance of products were obtained through the comparison with different guidelines. Findings About 34 per cent of analysed products did not comply with the tolerance limit according to the Food Act 1983, Malaysia (one way approach tolerance limit). Then, 73 per cent of products failed to comply with the tolerance leeway ±20 per cent (two-way approach) and 56 per cent of products did not comply with the tolerance limits set in the Local Authorities Coordinators of Regulatory Services. Research limitations/implications Many researches have proved that consumers used nutrition label as a tool to improve their healthy lifestyles. The misleading of nutrition label will elicit detrimental effect to consumers especially who always rely on the nutrition label before purchasing. Hence, credibility of nutrition label is imperative. However, this research only focussed on four major core nutrients. Nutrients such as trans-fat and sodium have proved that are detrimental to human’s health are not covered in the study. Practical implications First, this research could directly reflect the credibility of nutrition label in the market. The government of the country should improve the surveillance activity on nutrition label. Meantime, free trade activities especially on food industries are active now; an accurate nutrition label is the first key to success in the business. This research can inject awareness to food producers who incline to do global free trade business shall always assure the accuracy of the nutrition label no matter the tolerance or guidelines are different among the countries. Originality/value There are many research about improvement in consumers’ awareness towards nutrition label but very little research conducted on the accuracy of nutrition label. The main purpose of those research is to improve public health awareness but this may become insignificant if the values of nutrition label are inaccurate. Then, the asymmetric of tolerance limits would trigger awareness from policy makers or food manufacturers to be more responsible in providing credible nutrition label. At the end, consumers are protected from inaccurate nutrition labels and a healthy nation can be sustained.

There is limited information regarding the free sugar content of pre-packaged foods in Hong Kong. This study aims to assess the free sugar content and identify the most frequently used free sugar ingredients (FSI) in pre-packaged foods in Hong Kong. Data from 18,784 products from the 2019 FoodSwitch Hong Kong database were used in this analysis. Ingredient lists were screened to identify FSI. Total sugar content was derived from nutrition labels on packaging. Free sugar content was estimated based on adaptation of a previously established systematic methodology. Descriptive statistics of the total sugar and free sugar content, as well as the mean ± SD contribution of free sugar to total sugar of the audited products were calculated, stratified by food groups. Almost two-thirds (64.5%) of the pre-packaged foods contained at least one FSI. ‘Sugar (sucrose)’ was the most popular FSI that was found in more than half (54.7%) of the products. ‘Fruit and vegetable juices’ (median 10.0; IQR 8.3–11.5 g/100 mL) were found to have a higher median free sugar content than ‘Soft drinks’ (8.0; 6.0–10.6 g/100 mL). Mean ± SD contribution of free sugar to the total sugar content was 65.8 ± 43.4%, with 8 out of 14 food groups having >70% total sugar as free sugar. To conclude, free sugar, especially sucrose, was extensively used in a wide variety of pre-packaged products sold in Hong Kong. Further studies are needed to assess the population intake of free sugar in Hong Kong to inform public health policy on free sugar reduction.

Ultra-processed, pre-packaged foods are becoming a growing part of our diet, while displacing whole and minimally processed foods. This results in an increased intake of free sugar, salt, and saturated fats, that have a profoundly negative effect on health. We aimed to assess the trend in free sugar content in pre-packaged foods in Slovenia and evaluate the efficacy of industry self-regulations designed to combat the excess consumption of free sugar. A nation-wide data collection of the Slovenian food supply was performed in 2015 and repeated in 2017. In 2017, 54.5% of all products (n = 21,115) contained free sugars (median: 0.26 g free sugar/100 g). Soft drinks became the main free sugar source among pre-packaged goods (28% of all free sugar sold on the market) in place of chocolates and sweets, of which relative share decreased by 4.4%. In the categories with the highest free sugar share, market-leading brands were often sweeter than the average free sugar value of the category. This indicates that changes in on-shelf availability towards a greater number of healthier, less sweet products are not necessarily reflected in healthier consumers’ choices. Relying solely on voluntary industrial commitments to reduce free sugar consumption will likely not be sufficient to considerably improve public health. While some further improvements might be expected over the longer term, voluntarily commitments are more successful in increasing the availability of healthier alternatives, rather than improving the nutritional composition of the market-leading products. Additional activities are, therefore, needed to stimulate reformulation of the existing market-leading foods and drinks, and to stimulate the consumption of healthier alternatives.

AbstractObjectiveTo determine the presence of nutrition labels on pre-packaged food products, as well as to analyse the types of presentation.DesignThis was a descriptive study. The following characteristics were analysed: (i) presence and placement of the nutrition declaration (either as front-of-pack (FOP) or back-of-pack (BOP)); (ii) content of the presented information; (iii) presence of nutrition and health claims; and (iv) legibility of the written information.SettingsThree different types of retailers in Belgrade, Serbia.SubjectsA total of 2138 pre-packaged food products from ten categories.ResultsA nutrition declaration was found on 65·9 % of all tested products. It was displayed on the back of the packaging of 62·7 % of products and on the front of the packaging of 19·1 % of products. BOP was the most commonly observed in breakfast cereals, soft drinks, milk and instant soups (in total over 90 %), and the least common in meat products (21·5 %). FOP was predominantly displayed on breakfast cereals (65·0 %) and the least frequently on milk products (2·4 %). The ‘Big 4’ (energy value, protein, carbohydrate and fat contents) and the ‘Big 4 with additional information’ figured on 40·9 % of products. The ‘Big 8’ (‘Big 4’ plus sugar, saturated fat, fibre and sodium contents) and the ‘Big 8 with additional information’ were present less frequently (20·5 %). Nutrition claims and health claims appeared on very few products (6·6 % and 6·3 %, respectively). The proportion of products with insufficient legibility was 31·5 %.ConclusionsNutrition labelling in Belgrade, Serbia is not satisfactory. Mandatory regulations may be the best way to improve the current situation.

This study aims to examine the use of non-nutritive (NNSs) and low-calorie sweeteners (LCSs) in pre-packaged foods in Hong Kong and the differences in the number of NNSs/LCSs used between products from different regions. In a cross-sectional audit, the types of NNSs/LCSs used in 19,915 pre-packaged foods in Hong Kong were examined by searching the ingredients list of the included products for keywords related to 20 common NNSs/LCSs and their respective E-numbers. Prevalence of use of NNSs and LCSs, the co-presence of NNSs/LCSs and free sugar ingredients (FSI), and the number of NNSs/LCSs used in the included foods were computed. Pearson’s χ2 test was used to compare the total number of NNSs and/or LCSs used in food items from different regions. Sucralose (E955) was the most commonly used NNS (1.9%), followed by acesulfame K (E950, 1.6%). Sorbitol was the most commonly used LCS (2.9%). Overall, the use of LCSs was less common compared with NNSs (3.7% vs. 4.5%). The use of different types of NNSs varied substantially between food types. Notably, 20.2% of potato crisps and 15.2% of other crisps or extruded snacks contained at least one NNS and/or LCS. Co-presence of FSIs and NNSs/LCSs were most common in confectionery (15.7%) and snack foods (15.5%). Asian prepackaged foods were more likely to contain NNSs/LCSs (10.1%) compared with those from other regions. To conclude, NNSs/LCSs were used in a wide range of non-diet pre-packaged products which could be a public health concern due to their higher consumption frequencies than “diet” products.

From mad cows to McDonaldization to genetically modified maize, European food scares and controversies at the turn of the millennium provoked anxieties about the perils hidden in an increasingly industrialized, internationalized food supply. These food fears have cast a shadow as long as Africa, where farmers struggle to meet European demand for the certifiably clean green bean. But the trade in fresh foods between Africa and Europe is hardly uniform. Britain and France still do business mostly with their former colonies, in ways that differ as dramatically as their national cuisines. The British buy their "baby veg" from industrial-scale farms, pre-packaged and pre-trimmed; the French, meanwhile, prefer their green beans naked, and produced by peasants. Managers and technologists coordinate the baby veg trade between Anglophone Africa and Britain, whereas an assortment of commercants and self-styled agro-entrepreneurs run the French bean trade. Globalization, then, has not erased cultural difference in the world of food and trade, but instead has stretched it to a transnational scale. French Beans and Food Scares explores the cultural economies of two "non-traditional" commodity trades between Africa and Europe--one anglophone, the other francophone--in order to show not only why they differ but also how both have felt the fall-out of the wealthy world's food scares. In a voyage that begins in the mid-19th century and ends in the early 21st, passing by way of Paris, London, Burkina Faso and Zambia, French Beans and Food Scares illuminates the daily work of exporters, importers and other invisible intermediaries in the global fresh food economy. These intermediaries' accounts provide a unique perspective on the practical and ethical challenges of globalized food trading in an anxious age. They also show how postcolonial ties shape not only different societies' geographies of food supply, but also their very ideas about what makes food good.

This chapter reveals and discusses a case involving celiac disease (CD). CD is a common, lifelong, genetically-based autoimmune disorder that causes inflammation of the proximal small intestine. This disease is triggered by eating foods containing gluten, which causes intestinal discomfort. Gluten is a protein that is found naturally in wheat, barley, and rye and is common in foods such as bread, pasta, cookies, and cakes. Many pre-packaged foods, lip balms and lipsticks, hair and skin products, toothpaste and vitamin and nutrient supplements contain gluten, although it is rarely found in medicine. The key to living with CD is to follow a gluten-free diet. This case shows the role of medical nutrition therapy in managing and preventing the undesirable symptoms of CD. Moreover, it allows dietetic professionals to assess celiac patients' conditions and provide them with relief from undesirable symptoms, while also establishing an effective follow-up plan with each patient.

Background: In September 2018, the prohibition of partially hydrogenated oils (PHO) came into effect in Canada to reduce industrially produced trans fats (TFA) in the food supply to the lowest level possible. Canada’s public health objective is that ≥90% of the population consume <1% of total energy (1%En) as TFA (WHO recommendation). Objective: Estimate the intakes of TFA by Canadians before the PHO prohibition. Methods: Data from 19,670 participants of the cross-sectional Canadian Community Health Survey (CCHS)–Nutrition 2015 was analyzed. Foods were classified based on the source of TFA (industrially produced only (i-TFA), naturally occurring only (n-TFA), or a mix of both). Food content in TFA originated from 2016 label information and the 2015 Canadian Nutrient File. Mean usual intakes of total TFA and TFA from different sources were estimated for Canadians aged 1-75y. Results: For the overall population, the mean intake of total TFA represented 0.57%En (SE:0.001), with the 95 percentile at 0.93%En (SE:0.005). All age-sex groups had mean TFA intakes <1%E, ranging from 0.52 to 0.71%En. On average, foods containing only n-TFA provided >1/2 of total TFA intake (0.32%En, SE:0.005). Foods containing only i-TFA provided <1/3 of total TFA intake (0.19%En, SE:0.005). The target of ≥90% of the population consuming <1%En as TFA had already been achieved before the PHO prohibition in all age-sex groups, except children 1-3 years old, with 86% within target. In that group, foods containing only n-TFA provided >2/3 of total TFA intake (0.48%En, SE:0.02).Conclusions: Total TFA intakes in Canada before the PHO prohibition were relatively low, likely due to previous initiatives to reduce industrially produced TFA in foods, starting with labelling of the amount of TFA on most pre-packaged foods, which became mandatory in 2007. These analyses will be repeated using post-PHO prohibition data to continue monitoring progress after the prohibition.

"The aim of this work is to evaluate the shelf life of cow’s ricotta under MAP (Modified Atmosphere Packaging). MAP is a packaging technique commonly used in the food industry in order to control the microbial growth. After the extraction of the air present in the headspace of the package, a mixture of CO2, O2 and N2 in different percentage is usually introduced before the packaging sealing. Based on these premises, a design of experimental tests has been created in order to evaluate the effect of each process parameters. To perform these test, it is also required the creation of thermoformed trays (made with a multilayer material using PET/EVOH/PE) in which the ricotta was inserted and packaged in a modified atmosphere. After the time intervals established in the experimental program, the analysis of the MAP was carried out using a special instrument (“Oxybaby” made by Witt SpA), able to measure the quantity of gas present in the headspace of the thermoformed trays. Then a statistical analysis of the obtained results was carried out. The results showed that after 10 days the product was edible for all types of atmosphere, but at 20 and, especially, at 30 days, even in the trays wrapped with CO2, the product was not acceptable for human consumption. One of the possible solutions, in order to lengthen the shelf life of cow’s ricotta, consists in the pre-sterilization of the trays before the product packaging with a solution of H2O2."
