Nutritional Data on Selected Food Products Consumed in Oman: An Update of the Food Composition Table and Use for Future Food Consumption Surveys

Food composition data in the Eastern Mediterranean Region countries are often lacking, obsolete, or unreliable. The study aims to provide reliable nutrient data on food products consumed in Oman in order to evaluate their nutritional quality, the consistency of the nutrition labeling and claims, and, ultimately, the use for food consumption surveys and update the current food composition database. Contents of fat, fatty acids, carbohydrates, protein, sugars, and sodium were chemically analyzed in 221 foods and beverages. Products were classified according to their nutritional composition and the extent of processing and coded according to the FoodEx2 system. Labels and laboratory values were compared using the tolerance levels of the European Union. Results indicate that the nutrition labeling aligns with the values obtained in the laboratory, with the exception of 6.3% discrepancies in TFA content, where the reported values are higher than the appropriate reference values. The most frequent category (71.5%) was ultra-processed foods. In terms of inconsistencies in the nutritional claims, 5.1% of food products with claims did not comply with the statement "sugar-free" or "low salt". Our study provides evidence to support the necessity of comprehensive recommendations for consumers and food industries, which are aimed at enhancing the nutritional quality of products and augmenting consumer awareness.

[Study of composite mixtures based on durum wheat semolina and white beans flour for pasta production as specialized food products]

Increasing the number of chronic non-communicable diseases around the world is a critical social problem in many countries. In this regard, the creation of specialized foods that correct dysfunctions of the human body is a priority direction in science and food industry. Legumes are characterized by a high content of protein, minerals and trace elements, which determines their possible use as the main raw materials for creating specialized foods. The aim of this research was to present a medical, biological and technological justification for the possibility of producing pasta based on composite mixtures of durum wheat semolina and white bean flour as specialized foods with increased protein content and optimal mineral ratio. Material and methods. The objects of the study were grains of durum wheat (grade Krasnokutka-13), whole meal flour from white beans, composite mixtures in various percentages, and pasta from them. The nutritional and biological value of durum wheat semolina and bean flour was determined experimentally, the nutrient profile of the developed composite mixtures - by calculation. The rheological properties of dough from composite mixtures and the cooking properties of pasta made from them were assessed. Results. It has been established that increase in the proportion of white bean flour in composite mixes elevated calcium and protein content, optimized an amino acid profile, the ratio of calcium to phosphorus, significantly reduced the glycemic load. Bean flour introduction into composite mixtures positively affected the rheological properties of the dough and products from it, in particular, on the speed and energy intensity of dough kneading and aging processes of starched polysaccharides, however, lead to a decrease in dry pasta strength. The pasta made from composite mixtures meets the technological requirements for pasta in terms of a number of basic indicators, namely: the volume of dry pasta, the volume of pasta after cooking and the boilability coefficient. Conclusion. The rheological and technological properties of composite mixtures and their nutrient profile make it possible to recommend them for the production of pasta, as specialized foods.

Carcass Yields and Meat Composition of Roosters of the Portuguese Autochthonous Poultry Breeds: "Branca", "Amarela", "Pedrês Portuguesa", and "Preta Lusitânica"

Poultry meat is an important part of the human diet, and the valorisation of autochthonous breeds is a determinant for the sustainability of the rural areas. The increasing demand for niche products demands for better knowledge of the carcass characteristics and meat quality of these local populations. The present study aims to characterise the roosters' meat from the "Branca" (BR), "Amarela" (AM), "Pedrês Portuguesa" (PP), and "Preta Lusitânica" (PL) breeds. A total of 80 birds (n = 20 per breed) between 38 and 42 weeks old were slaughtered. The physicochemical and nutritional composition were determined in the breast and drumstick meat. The meat of the PL breed had a higher (p ≤ 0.05) pH value, the AM meat revealed a water-holding capacity (WHC) of superior value and moisture content (p ≤ 0.05), while the BR breed had the highest (p ≤ 0.05) ash content. On the other hand, it was observed that the PP meat had a higher (p ≤ 0.05) yellowness index (b*). The breast meat exhibited, in all breeds, a lower pH value, WHC, redness (a*), and lipid content and greater (p ≤ 0.05) lightness (L*), b*, moisture, and ash and protein contents compared to the drumstick. Furthermore, it presented higher (p ≤ 0.05) K, P, and Mg contents and a superior proportion of total and sensorial relevant amino acids. Regarding the fatty acid profile, the breed differences were more significant in the drumstick, with the AM breed lipids presenting a higher (p ≤ 0.05) percentage of MUFAs in the fat, a lower atherogenic index, and a higher (p ≤ 0.05) value for the hypocholesterolemic/hypercholesterolemic fatty acids ratio, while the BR breed lipids presented a higher (p ≤ 0.05) percentage of PUFAs and PUFAs/SFAs ratio and a lower n-6/n-3 ratio. Considering the results obtained, it can be concluded that the meat from these breeds is a wholesome dietary option, distinguished by a favourable overall nutritional composition marked by elevated protein content, reduced lipid amounts, and amino and fatty acid profiles with desirable nutritional indices.

Detailed whole-body nutrient analysis identifies differences in feeding ecology between related fish species: The case of Orestias native Andean killifish in Lake Titicaca

Body nutrient profiles in ecological studies allow for relating the nutritional status of consumers and their effects on the movement and retention of elements in ecosystems, as well as reflecting feeding conditions and habitat quality. This study compared the detailed whole-body nutrient composition (macronutrients, minerals, fatty acids and amino acids) of two omnivorous natives Orestias killifish from Lake Titicaca (Orestias agassizii and Orestias luteus, Valenciennes), the largest lake in the Andes, as an indirect tool to understand differences in their feeding ecology. Although both species are usually described as omnivorous fish, both have amphipods (Hyalella spp) as their main food source. Our results showed that both killifish had a comparable macronutrient composition, and the mineral concentrations of Mg, P and Ca (reflecting bony structures) differed between them. Many of the saturated fatty acids were significantly lower in O. luteus, and O. agassizii had higher concentrations of cis-vaccenic acid (18:1n11 (cis)), supporting the idea of a higher algal contribution to the diet of this fish. The lower histidine and higher taurine concentrations in O. agassizii compared with O. luteus (independent of body size) may reflect its ubiquitous behaviour and plasticity. This study shows how whole-body nutrient analysis can identify differences in feeding ecology and feeding behaviour between related species.

Nutritional Assessment of Plant-Based Meat Products Available on Hong Kong Market: A Cross-Sectional Survey

BACKGROUND

Plant-based meat (PBM) takes up ever-increasing market shares and draws great attention from both customers and retailers these days. However, little is known about the nutritional quality of PBM products.

OBJECTIVE

This study intended to profile and evaluate the overview nutrition of PBM with equivalent meat products on the Hong Kong market.

METHODS

We conducted a cross-sectional survey of 274 PBM and 151 meat products from 27 different brands on the Hong Kong market in October 2022. The nutritional differences between PBM and meat products were assessed using analysis of covariance (ANCOVA) and two independent sample t-test. The nutritional quality of PBMs was evaluated according to nutrient reference value, front-of-package (FoP) criteria and nutritional score.

RESULTS

PBM had relatively lower energy density, total fat, saturated fat, protein, and salt compared to meat. According to the FoP criteria, 91.36%, 17.88%, and 99.34% of PBMs were labeled as medium to high in fat, salt, and sugar, respectively. Through ingredient analysis of 81 PBM products, soy and canola were the main source of protein and fat.

CONCLUSIONS

PBM products have a roughly better nutrient quality compared to muscle-based meat, though there is still potential for further refinement in terms of production, consumption, and regulation.

Nutritional aspects of commercial infant and toddler food products sold in Turkey

Background: In recent years, there has been an increase in the variety and consumption of commercial infant and toddler food products. Aim: The aim of this study is to evaluate the nutritional profiles of commercial infant and toddler food products sold in Turkey. Methods: A cross-sectional survey of the nutritional composition of products available at in-store and online supermarkets in Turkey was derived from the nutritional information panel on the product label or information provided on manufacturer websites in March 2023. The targeted age group, package type, serving size, ingredients list, and nutrition information (energy [kcal], protein [g], total fat [g], carbohydrate [g], dietary fiber [g], total sugar [g], and sodium [mg] per 100 g) were recorded. Results: Of the 189 products identified, more than 90% (n = 47) of the first foods were fruit-based, while 2% (n = 4) contained only vegetables. Almost half of the products (n = 89, 49%) contained added sugar or sweeteners, 41 (22%) had added sugar, and 1 in 3 products (n = 68, 36%) had sugar from fruit-based sources. One in 10 products (n = 18, 9.5%) contained added salt while 40% of the products (n = 76) were above the WHO Europe sodium standards. Almost half of the products (n = 6, 46%) targeting the 12 months older age group were pureed foods using squeeze pouch packaging. Conclusions: The majority of commercial infant and toddler food products did not adhere to nutrition guidelines. There is a need for stronger composition standards for commercial infant and toddler food products by reducing sugar and sodium content, reducing the use of fruits and sweet vegetables, and increasing the variety of products containing different types of vegetables.

Comparative Assessment of the Nutritional Profile of Meat Products and Their Plant-Based Analogues

Vegetarian and vegan diets are increasingly being adopted in Spain, a trend mainly driven by ethical concerns for animal welfare and the environment. This has resulted in a growing market for plant-based substitutes of meat products. However, available data on the nutritional value of such meat analogues in Mediterranean countries are still limited. In this study, the labelling information of four categories of plant-based meat analogues (n = 100) and the corresponding conventional meat products (n = 48) available on the Spanish market was surveyed and compared. The nutrient content of plant-based meat analogues varied significantly, due to the wide range of ingredients used in their formulation. Some of these products were found to have a low protein content, which in others was enhanced by the addition of cereals and legumes. Compared to the meat products, the plant-based analogues contained lower levels of total fat as well as saturated fat, which ranged from 30% of total fat in burgers to less than 15% in meatballs, sausages, and nuggets; in contrast, they contained higher amounts of fiber and complex carbohydrates. Overall, the meat analogues cannot be considered as nutritionally equivalent substitutes to conventional meat products due to a high variability of protein content and other nutrients.

Sustainable Strategies for Increasing Legume Consumption: Culinary and Educational Approaches

Legumes are nutrient-dense crops with health-promoting benefits. However, several barriers are associated with their consumption. Emerging issues including food neophobic tendencies or taboos, unclear dietary guidelines on legume consumption, health concerns, and socio-economic reasons, as well as long cooking procedures, adversely affect legume consumption frequency. Pre-treatment methods, including soaking, sprouting, and pulse electric field technology, are effective in reducing the alpha-oligosaccharides and other anti-nutritional factors, eventually lowering cooking time for legumes. Extrusion technology used for innovative development of legume-enriched products, including snacks, breakfast cereals and puffs, baking and pasta, represents a strategic way to promote legume consumption. Culinary skills such as legume salads, legume sprouts, stews, soups, hummus, and the development of homemade cake recipes using legume flour could represent effective ways to promote legume consumption. This review aims to highlight the nutritional and health effects associated with legume consumption, and strategies to improve their digestibility and nutritional profile. Additionally, proper educational and culinary approaches aimed to improve legumes intake are discussed.

[Juices in a healthy diet: recommendations for consumption based on chemical composition data]

Juices from fruits and vegetables show a complex composition, they contain several hundred different substances. In addition to water and common metabolites such as carbohydrates, juices contain organic acids, minerals and trace elements, vitamins, polyphenolic and other biologically active compounds. Moreover, each type of juice is characterized by a unique set of natural compounds and is able to contribute to providing the human body with micronutrients. The study and analysis of the nutrient composition of commercially produced juices, which are currently the most consumed by the population, contributes to understanding the place of juices in healthy nutrition and is intended to contribute to the development of relevant recommendations for their use. The purpose of the research was to evaluate their nutritional density and nutritional value based on the analysis of published data on the nutrient composition of juices, and then offer recommendations on the use of juices in healthy nutrition. Material and methods. The analysis of nutrient profiles of ten popular types of juices presented on the market of the Russian Federation (apple, orange, grapefruit, grape, tomato, pomegranate, pineapple, carrot, cherry, peach) was carried out. Nutritional density indices (NDI) were calculated as the degree of satisfaction of a person's need for a particular nutrient when filling the calorie value of the diet (2500 kcal) only with this product. The integral score characterizing the degree of the juice compliance with an optimally balanced daily diet, taking into account the energy content, which provides 5% of energy, was also calculated. Results. NDI and the integral score of various types of juices show that juices have a high nutritional value and can make a significant contribution to the intake of some nutrients and bioactive compounds. The most important substances from juices are polyphenolic compounds (flavonoids, phenolic acids) and carotenoids (β-carotene, lycopene). All juices also contain significant level of potassium and magnesium, and they can serve a source of some vitamins and minerals (depending on the individual nutrient profile): citrus juices are the source of vitamin C and folates, pineapple - of manganese, vitamin C and B vitamins, apple - chromium, grape - molybdenum, iron and chromium, pomegranate - copper and tannins, cherry - iron, copper and pantothenic acid; vegetable juices, such as tomato and carrot juices, contain a wide range of essential micronutrients. Juices with pulp and juices without clarification can be a source of pectins and dietary fiber. Modeling of juice rotation in the diet shows that in this case, 75% of the nutrients (from 32 studied) will have a NDI1, i.e. provide a meaningful intake with juice. Conclusion. The characteristic features for each type of juice regarding the content of vitamins, minerals and other biologically active compounds should be taken into account to assess the place of juices in healthy nutrition and develop modern recommendations for their consumption. Such recommendations include alternating different types of juices in the diet, as well as, if necessary, the choice of certain juices to include in the diet, depending on the individual's nutritional needs.

Importance of Carbohydrate Quality: What Does It Mean and How to Measure It?

Dietary carbohydrates are our main source of energy. Traditionally, they are classified based on the polymer length between simple and complex carbohydrates, which does not necessarily reflect their impact on health. Simple sugars, such as fructose, glucose, and lactose, despite having a similar energy efficiency and caloric content, have very distinct metabolic effects, leading to increased risk for various chronic diseases when consumed in excess. In addition, beyond the absolute amount of carbohydrate consumed, recent data point out that the food form or processing level can modulate both the energy efficiency and the cardiometabolic risk associated with specific carbohydrates. To account for both of these aspects-the quality of carbohydrates as well as its food form-several metrics can be proposed to help identifying carbohydrate-rich food sources and distinguish between those that would favor the development of chronic diseases and those that may contribute to prevent these. This review summarizes the findings presented during the American Society of Nutrition Satellite symposium on carbohydrate quality, in which these different aspects were presented.

Ultraprocessed food consumption and dietary nutrient profiles associated with obesity: A multicountry study of children and adolescents

This study assessed associations between ultraprocessed food consumption and dietary nutrient profile linked to obesity in children and adolescents in Argentina, Australia, Brazil, Chile, Colombia, Mexico, the United Kingdom, and the United States using nationally representative data collected between 2004 and 2014. Linear regression models were used to evaluate associations between dietary share of ultraprocessed foods (country and age group-specific quintiles and a 10% share increase) and the energy density of diets and their content of free sugars and fiber. Ultraprocessed foods, defined by the NOVA system, ranged from 18% of total energy intake among preschool children in Colombia to 68% among adolescents in the United Kingdom. In almost all countries and age groups, increases in the dietary share of ultraprocessed foods were associated with increases in energy density and free sugars and decreases in fiber, suggesting that ultraprocessed food consumption is a potential determinant of obesity in children and adolescents. Effective global policy action to address growing ultraprocessed food consumption and childhood obesity is urgently needed.

Nutritional Quality of Plant-Based Meat Products Available in the UK: A Cross-Sectional Survey

Plant-based meat (PBM) has been gaining popularity due to increasing concerns over health, animal welfare, and environmental issues linked to animal foods. This study aimed to compare the nutrient profile of PBM with equivalent meat products. We conducted a cross-sectional survey of 207 PBM and 226 meat products available from 14 retailers in the UK. We extracted data on energy density, total and saturated fat, protein, fiber, and salt per 100 g from product packaging and calculated the nutrient profile of each product. Compared to meat, PBM had significantly lower energy density, total fat, saturated fat, protein, and significantly higher fiber. Salt content was significantly higher in five out of six PBM categories. Based on the UK’s Nutrient Profiling Model, 14% of PBM and 40% of meat products were classified as “less healthy” (p < 0.001). When considering the UK’s front-of-pack labelling criteria 20% of the PBM and 46% of meat products were considered high in either total fat, saturated fat, or salt (p < 0.001). Nearly three quarters of PBM products did not meet the current UK salt targets. PBM products have a better nutrient profile compared to meat equivalents. However, more progress is needed to reduce salt in these products.

The Future of Moringa Foods: A Food Chemistry Perspective

The tree Moringa oleifera Lam. provides its leaves, pods, flowers and seeds for human nutrition. The chemical profile of all these Moringa products varies substantially, not only among the different parts of the plants used. Cultivating, processing as well as storage conditions chiefly determine the contents of nutrients and anti-nutritive constituents. Anti-nutrients, e.g., phytic acid or tannins, are present in notable amounts and may affect micronutrient bioavailability. Although Moringa oleifera products have been promoted for several health benefits and are discussed as an alternative treatment in various diseases, risk assessment studies evaluating contamination levels are scarce. Recent investigations have demonstrated alarming contents of heavy metals, polycyclic aromatic hydrocarbons and mycotoxins in Moringa oleifera products, indicating the need for a comprehensive risk assessment and contingent legal regulation of these products. In this mini review, we briefly outline pivotal, food chemistry and nutrition related data on Moringa preparations in order to stimulate in-depth research to close the presented knowledge gaps.

Breakfast Cereals Intended for Children: Opportunities for Reformulation and Potential Impact on Nutrient Intake

Ready-to-eat cereals (RTECs) have become a popular breakfast option claiming to provide important nutrients to children's diets, despite being a source of excess sugar and, therefore, a health concern. Thus, food reformulation constitutes an important public health strategy that could benefit from inputs provided by nutrient profiling. This study aimed to assess the adequacy of the RTECs for children available in Portuguese supermarkets, applying three nutrient profile models (NPMs)-the nutrient profile model of the World Health Organization's Regional Office for Europe (WHO-EURO), the profile of the private-sector EU Pledge (EU-Pledge), and the national model developed by the Directorate-General of Health (NPM-PT)-in order to explore the potential for reformulation of the RTECs identified as not adequate and evaluate the impact of RTECs' reformulation on the nutritional quality of Portuguese children's diets. In total, 78 RTECs intended for children were assessed and two scenarios-current (not considering reformulation) and alternative (considering reformulation to accomplish the nutrient profile requirements)-were considered to assess the impact of reformulation on nutritional quality. Across all RTECs, only 5.1% could be promoted to children according to the considered NPMs. The most common nutrients requiring reformulation were sugar, saturated fatty acids (SFA), salt, and dietary fiber. The scenarios of reformulation considered could reduce the RTECs average content of total sugars, SFA, and salt by 43%, 8.7%, and 1.1%, respectively, and dietary fiber intake could be increased by 34%. Thus, these results support policies to implement reformulation strategies for developing healthier food products to be promoted to children.

Use of advertising strategies to target children in sugar-sweetened beverages packaging in Mexico and the nutritional quality of those beverages

BACKGROUND

A product package can be a powerful marketing tool to persuade and attract consumers at the point-of-sale. Evidence shows that most advertised products have low nutritional quality. Currently, Mexico has incorporated advertising regulations on food and beverage packaging.

OBJECTIVES

To analyze the advertising strategies used to target children on packaging and to assess the nutritional quality of sugar-sweetened beverages available in the Mexican market.

METHODS

Photographs of 2380 beverages available in retail stores in Mexico City from January to March 2017 were analyzed. Beverages were classified as displaying child-directed strategies or nondirected strategies. Nutrition quality was evaluated using the Pan American Health Organization nutrient profile model.

RESULTS

The use of characters was the most frequent strategy among beverages with child-directed strategies (82.0%). The evaluation of nutrition quality found that 88.0% (P < .001) of sugar-sweetened beverages with child-directed strategies were excessive in free sugars and 56.9% (P < .001) contained other sweeteners. Beverages with more than two advertising strategies have the highest proportion of excessive free sugars (93.4%, 95% CI 82.8-98.6).

CONCLUSIONS

The use of characters and other visual strategies were frequently used in the packaging of sugar-sweetened beverages with child-directed strategies. In addition, these beverages are excessive in free sugars and contain a large number of products with other sweeteners.

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.

Prevalence of Product Claims and Marketing Buzzwords Found on Health Food Snack Products Does Not Relate to Nutrient Profile

Growth in the consumer health and wellness industry has led to an increase of packaged foods marketed as health food (HF) products. In consequence, a ‘health halo’ around packaged HF has arisen that influences consumers at point-of-purchase. This study compared product claims (nutrient content claims (NCC), health claims and marketing ‘buzzwords’) displayed on packaged HF snack products sold in HF stores and HF aisles in supermarkets to equivalent products sold in regular aisles (RA) of supermarkets. Product Health Star Rating (HSR), nutrient profile and price were also compared. Data were collected for 2361 products from three supermarket chains, two HF chains and one independent HF store in Sydney, Australia. Mann-Whitney U tests compared the product claims, HSR, nutrient composition and unit ($) price. HF snacks displayed significantly more product claims per product compared to RA foods (HSR ≤ 2.5), median (IQR) 5.0(4.0) versus 1.0(2) and (HSR > 2.5) 4.0(4.0) versus 3.0(4), respectively (p < 0.001). A significantly different HSR was evident between HF and RA snack products, median 2.5(0) versus 2.0(1.5), respectively (p < 0.001). HF snacks cost significantly more than RA snack foods, irrespective of product HSR (p < 0.001). These findings support the recommendation for revised labelling regulations and increased education regarding consumers food label interpretation.

Profiling of Nutraceuticals and Proximates in Peanut Genotypes Differing for Seed Coat Color and Seed Size

A total of 60 genotypes of peanut comprising 46 genotypes selected from ICRISAT mini core collection and 14 elite cultivars with differing kernel color and size were used to profile the nutritional parameters such as proximates (moisture, fat, ash, crude protein, crude fiber, carbohydrate content) and nutraceuticals (total polyphenol content and total antioxidant activity). The genotypes showed varied kernel color ranging from white to purple. Kernel skin color was quantified using colorimetry, and the color parameters were expressed as CIELAB color parameters. In total, nine morphological traits, six yield related traits, eight nutritional traits and eleven color parameters were observed across 60 genotypes. The sixty genotypes were grouped into ten clusters based on the color strength. Among them, Cluster-III with dark red seeds had the maximum fat content and total polyphenol content (TPC). Cluster-VI with light pink colored seeds had high antioxidant activity (AOA) and Cluster-X with white colored seeds had highest moisture and crude protein content. Color strength (K/S) was found to be positively correlated with TPC. Another color parameter, redness/greenness (a*) was found to be positively correlated with AOA. However, seed size was positively correlated with the crude protein content, but not with any other nutritional traits under study. The population studies based on the genotypic data indicated two distinct groups pertaining to botanical types of peanut. The marker-trait association (MTA) using single marker analysis indicated 75 major MTAs for most of the nutritional traits except for moisture content. The markers associated with nutritional parameters and other important yield related traits can further be utilized for genomics-assisted breeding for nutrient-rich peanuts.

Nutritional Characteristics of Prepacked Feta PDO Cheese Products in Greece: Assessment of Dietary Intakes and Nutritional Profiles

Feta cheese, a protected designation of origin (PDO) food, is one of the most important Mediterranean food products. Although it is the cheese with the highest consumption in Greece, the nutritional characteristics of products available in the market, as well as their contribution to the Greek diet, have not been evaluated in detail. In the present study, the basic nutritional content of 81 prepacked feta cheese products available in the Greek market were recorded based on their labels. This was combined with consumption data to provide an overall picture of feta cheese’s contribution to the Greek diet. The nutrient contents per 100 g ranged as follows. Energy: 221–343 kcal, total fat: 20–29 g, saturated fat: 12.8–20.3 g, carbohydrates: 0–3.1 g, sugars: 0–3 g, proteins: 13.1–21.0 g and salt: 1.2–5.1 g. The median feta daily individual consumption was found to be 39 g, ranging from 20 g to 100 g (fifth and 95th percentiles, respectively). The nutritional intake analysis as a percentage of dietary reference intake (DRI) showed that saturated fat and salt are ranked on the top of the list, with intakes reaching 101.5% and 85% respectively. The products were also evaluated against five nutrient profile models and their potential use under statutory requirements and policy development are discussed.

[Carrot juice nutritional profile]

Carrot juice is one of the main products of carrot processing and the second most popular vegetable juice after tomato. Due to the presence of a complex of various nutritive and biologically active substances (BAS) carrot juice can make a significant contribution to maintaining human healthy diet. The aim of the study was to establish the nutrient profile of carrot juice.

MATERIAL AND METHODS

A study of parameters of carrot juice of industrial production, characterizing its nutritional and biological value was carried out. The results of these experiments were compared with the data of BAS profiles of carrot juice from reference books and scientific publications.

RESULTS AND DISCUSSION

The established nutrient profile includes data about content of more than 30 nutritients and BAS. The sucrose is the predominant carbohydrate in carrot juice; glucose and fructose concentrations are substantially lower. Among organic acids predominates L-malic acid whereas content of citric acid is usually 5-10 fold lower than that of L-malic acid. The total acidity of carrot juice is low, on average 0.25 mg of organic acids is present in 100 cm³ of juice. Carrot juice is a relatively rich source of a number of vitamins and minerals. A serving (200-250 cm³) of industrial carrot juice on average contains around 18% of the recommended daily intake (RDI) for potassium, 9% for magnesium, 8% for iron, 12% for copper and 14% for manganese. Vitamins are represented to a large extent by β-carotene and other carotenoids (more than 400% of the RDI in a serving), as well as niacin, biotin and pantothenic acid - about 7% of the RDI in a serving for each of these vitamins. The content of vitamins E and K in serving averages 17 and 10% of the RDI respectively. Not clarified carrot juice contains about 1.1 g of dietary fiber in 100 cm³, including pectins - about 0.2 g/100 cm³.

CONCLUSION

Based on the results of this investigation the carrot juice might be considered as a substantial source of minor BAS mostly carotenoids, vitamins E and K, group B vitamins: niacin, biotin, pantothenic acid, mineral substances: potassium, magnesium, iron, copper, manganese, as well as dietary fiber.

[Peach juice-puree nutritional profile]

Peach fruits (Prunus persica L.) contain a complex of nutritive and biologically active substances. The extraction of juice from peaches is relatively difficult due to the high content of fruit pulp so for the purposes of the juice industry, most peaches are processed in puree which is the basis for the production of peach juice products. Data on the nutrient content in peach juices-purees are few and require clarification and addition as applied to industrial products. The aim of the study was to investigate and update the composition of main nutrients of peach juice-puree. Material and methods. The nutrient composition of peach juice products of industrial production has been studied. Analysis of the results obtained in conjunction with the analysis of the data of reference books and scientific publications regarding peach fruits and juices-purees from them has been performed. Results and discussion. Nutrient profile of peach juice-puree has been established. The nutrient profile shows the content of more than 30 nutritive and biologically active substances. The prevailing saccharide in peach juice-puree is sucrose; glucose and fructose are present in lower concentrations. In addition to sugars, peach juice-puree contains sorbitol - about 0.4 g per 100 g. The total acidity of peach juice-puree is low, in 100 g there is an average of 0.5 g of organic acids, most of which are L-malic and citric acids. Regarding the polyphenols of peach juice-puree, the most significant are hydroxycinnamic acids, mostly chlorogenic, at the concentration of about 10 mg/100 g. The main type of peach juice products on the market are peach nectars containing 40-50% of juicepuree. Peach nectar is rich in vitamin E - more than 20% of the daily requirement per serving, dietary fiber (15% of the daily requirement for pectins and 5% of total dietary fibers), and the content of hydroxycinnamic acids in it fully satisfies or exceeds the adequate daily intake. A serving of peach nectar also contains on average 7% of daily requirement for β-carotene, 8% in copper, 6% in potassium. Conclusion. The most significant micronutrient and minor biologically active substances for peach juice products are dietary fibers, hydroxycinnamic (chlorogenic) acids, β-carotene, vitamin E, and potassium and copper.

[Pomegranate juice nutritional profile]

Pomegranate juice is one of the main products of pomegranate processing with high content of a complex of polyphenolic compounds. It possesses high antioxidant activity. The aim of the study is to establish the nutritional profile of pomegranate juice. Material and methods. A research of nutrient composition of commercial pomegranate juice and analysis of the results in conjunction with the data of chemical composition present in reference books and scientific publications have been carried out. Results and discussion. The nutrient profile of pomegranate juice has been defined. The nutrient profile shows the content of more than 30 nutrients and biologically active substances. Sugars of pomegranate juice are represented by glucose and fructose in approximately equal concentrations. Citric and L-malic acids prevail of the organic acids in pomegranate juice while the content of citric acid, as a rule, is several times higher than the content of L-malic. The total acidity of pomegranate juice is high, on average 1.1 g of organic acids is present in 100 cm³ of juice.

[Pineapple juice nutritional profile]

Knowledge about food composition is necessary both for specialists to assess the state of nutrition of the population and develop recommendations on nutrition, as well as for consumers to organize healthy individual nutrition. Russian Union of Juice Producers together with research organizations is working to systematize and expand knowledge about the composition of juices, as one of the important elements in the structure of human nutrition. Aim is to establish the nutrient profile of pineapple juice. Material and methods. Data analysis of reference books and scientific publications, conducting physic-chemical studies of industrially produced pineapple juice. Results and discussion. The nutrient profile shows the content of more than 30 nutritive and bioactive compounds in pineapple juice. Sugars in pineapple juice are represented by glucose, fructose and sucrose in an average ratio of 1:1:1.6, organic acids are mainly citric and L-malic acids, while the content of citric acid is 2-4 times higher than that of L-malic. A portion of industrially produced pineapple juice on average contains 10% of the daily human requirement for potassium and magnesium, about 15% for copper, 60-70% for vitamin C. The content of vitamin B1 and folate is about 7% of daily recommended level, vitamin B₆ - about 12%. Pineapple juice is a source of manganese - a portion contains more than 100% of the adequate level of daily consumption of this trace element. Polyphenolic compounds are mainly represented by hydroxycinnamic acids, among which synaptic acid and its derivatives and p-coumaroyl chinic acid predominate (45-80% of all hydroxycinnamic acids in total). The content of hydroxycinnamic acids per serving averages 30% of the adequate level of their daily intake. Pineapple juice shows proteolytic activity (about 1 pe per 1 g of dry matter), which is associated with the content of the complex of proteolytic enzymes in pineapples. Conclusion. The most significant from the point of view of providing a human body with micronutrients and minor bioactive compounds for pineapple juice are manganese, vitamin C, hydroxycinnamic acids, copper, potassium, magnesium, and B vitamins (B₁, B₆, folates).

Nutrient Profiling Is Needed to Improve the Nutritional Quality of the Foods Labelled with Health-Related Claims

Health-related claims on food products influence consumers and their food preferences. None of the European countries have restricted the use of health claims to foods of high nutritional quality despite the regulatory background provided by the European Union in 2006. We evaluated the nutritional quality of foods labelled with claims available in the Slovenian market using two nutrient profile models—Food Standards Australia New Zealand (FSANZ) and European World Health Organization Regional office for Europe model (WHOE)—and compared the results to the nutritional quality of all available foods. Data for prepacked foods in the Slovenian food supply were collected in 2015 on a representative sample (n = 6619) and supplemented with 12-month product sales data for more accurate assessments of the food supply. A considerable proportion of foods labelled with any type of health-related claim was found to have poor nutritional quality. About 68% of the foods labelled with health-related claims passed FSANZ criterion (75% when considering sales data) and 33% passed the WHOE model (56% when considering sales data). Our results highlight the need for stricter regulations for the use of health-related claims and to build upon available nutrient profiling knowledge to improve nutrition quality of foods labeled with health-related claims.

[Tomato juice nutritional profile]

Every juice contains a unique set of nutritive and biologically active substances, exhibiting the properties of the named fruit or vegetable. To characterize the nutritional profile of tomato juice, the literature data (including official reference books) and the results of studies of domestic industrially produced tomato juices conducted by the Russian Juice Producers Union (RSPS) and its members have been analyzed and summarized. From the point of view of providing a man with micronutrients and minor biologically active substances, tomato juice is a significant source of antioxidants - carotenoids and vitamin E, as well as several minerals and trace elements. The amount of lycopene in a glass of tomato juice (200-250 ml) completely satisfies or exceeds the recommended daily intake of this carotenoid; the level of β-carotene in the same volume of juice provides about 20% of the recommended daily intake of vitamin A; potassium and copper - 12-15%, magnesium, iron, manganese and phosphorus - about 5%. Tomato juice is a source of dietary fiber, including soluble dietary fiber (pectin). A glass of tomato juice contains about 12% of the recommended daily intake of pectins and about 8% of dietary fiber. Wherein the calorie content of tomato juice is low - an average of 19 kcal/100 ml. The article continues a series of publications on juices nutrient profiles.

[Sour cherry juice nutritional profile]

Russia is one of the main producers of sour cherry, along with Turkey and Poland, and juice products from sour cherry are widely represented in the trade network. Sour cherry contains practically no sucrose, has a high content of organic acids, is rich in mineral and polyphenolic compounds, in particular, in anthocyanins, which give it a bright color. Sour cherry is close to many berries by its composition. At the same time, the literature data on the content of various natural substances in sour cherry juice are not numerous and need to be clarified, especially with reference to the industrially produced juice products. Organic acids of sour cherry juice are represented mainly by L-malic acid (1.2-2.7 g/100 ml). The most significant substances of sour cherry juice are polyphenolic compounds - flavonoids, mainly represented by anthocyanins (about 70% of them is cyanidin-3-O-glucosylrutinoside); phenolic acids - hydroxycinnamic acids, mainly represented by chlorogenic acids and 3-coumaroylquinic acid, as well as mineral substances - potassium, magnesium, copper and manganese. Sour cherry juice has a high acidity and is usually consumed in the form of nectars. Flavonoids content in a portion of sour cherry nectar is about 15% of adequate daily intake, anthocyanins - 20%, and the content of hydroxycinnamic acids - exceeds it. One portion of nectar contains on the average 10% of the daily requirement of the human body in copper and manganese, 6% in potassium and 3% in magnesium.

[Grape juice nutritional profile]

The nutrient profile of grape juice is presented on the basis of reference books data analysis, scientific publications and research results. The profile contains more than 30 food and biologically active substances (BAS). Grape juice does not have high acidity, it contains on average 0.4 g of organic acids per 100 cm³. Tartaric acid and L-malic acid are major acids in grape juice. The presence of tartaric acid is a distinctive feature of grape juice, in other juices it presents extremely rare and only in traces. Potassium, magnesium, iron, manganese, as well as flavonoids and hydroxycinnamic acids are the most important for grape juice from the point of view of providing humans with micronutrients and minor BAS. Juices from red/purple grapes varieties contain anthocyanins (on average 3 mg/100 cm³), the color of grapes and grape juices are associated with them, about 50% of the anthocyanins are malvidin glycosides. Resveratrol (an average of 0.01 mg/ 100 cm³), a stilbenoid, is also found in grape juices, this substance is widely studied recently due to its high antioxidant activity. Caftaric acid prevails among hydroxycinnamic acids presented in grape juice (on average 5 mg/100 cm³). A portion of industrial grape juice contains, on average, 6-10% of human daily need for potassium, about 5-8% for magnesium, iron and manganese. The content of flavonoids per serving is about 25% of the adequate level of daily consumption, and the content of hydroxycinnamic acids exceeds it. Studies of fresh grapes purchased in commercial networks show that the content of magnesium, iron and manganese in grape juices of industrial production is comparable to the content of these micronutriens in fresh fruit.

[Grapefruit juice nutritional profile]

Based on the published data on the content of nutritive (NS) and biologically active substances (BAS) and the results of studies of various samples of domestic industrial grapefruit juice, the article presents the nutrient profile of grapefruit juice containing data about more than 30 NS and BAS. Grapefruit juice is one of the relatively low-calorie fruit juices - 100 ml of grapefruit juice contains an average of 39 kcal. Like other citrus juices, it is rich in organic acids, the main of which is citric acid (0.8-2 g/100 ml). Potassium, magnesium, vitamin C, as well as flavonoids (mostly narigin) are the most significant for the estimation of nutritional and biological value of grapefruit juice of industrial production. A glass of grapefruit juice contains, on average, about 10% of the daily requirement in potassium, 6% - in magnesium and about 100% - in vitamin C. The amount of flavonoids in a glass of grapefruit juice provides up to 60% of the adequate daily intake. Conducted studies of fresh grapefruits purchased in the trade network show that the content of potassium, magnesium and vitamin C in grapefruit juice of industrial production is comparable to the content of these micronutrients in fresh fruits.

Characterization of the Types of Sweeteners Consumed in Honduras

Sweeteners are found in all types of foods, and their high consumption is associated with chronic degenerative diseases, such as diabetes and obesity, among others. A characterization was carried out of food products with sweeteners from the three biggest supermarkets at a national level; they were identified by the list of ingredients and classified according to caloric or non-caloric intake, and pursuant to their country of origin. A statistical interpretation of results was made using descriptive measures such as the number of times the sweeteners were found in the formulation of the products and how many of them were found in a product at the same time. In total, 341 products were evaluated and classified according to the processed food categories of the Pan American Health Organization (PAHO) nutrient profile. The category of beverages had the highest quantity of products with sweeteners, and their consumption by the inhabitants represents a high exposure. Overall, 60.1% of the products evaluated were of US origin; these US exports have a significant impact on the Honduran market. A high-fructose corn syrup caloric sweetener was the one most frequently found in these products; at least 51% are combined with additional sweeteners to increase the sweetening effect.

Effects of interpretive nutrition labels on consumer food purchases: the Starlight randomized controlled trial

Background: Nutrition labeling is a prominent policy to promote healthy eating.Objective: We aimed to evaluate the effects of 2 interpretive nutrition labels compared with a noninterpretive label on consumer food purchases.Design: In this parallel-group randomized controlled trial, we enrolled household shoppers across New Zealand who owned smartphones and were aged ≥18 y. Eligible participants were randomly assigned (1:1:1) to receive either traffic light labels (TLLs), Health Star Rating labels (HSRs), or a control [nutrition information panel (NIP)]. Smartphone technology allowed participants to scan barcodes of packaged foods and to receive allocated labels on their smartphone screens. The primary outcome was the mean healthiness of all packaged food purchases over the 4-wk intervention period, which was measured by using the Food Standards Australia New Zealand Nutrient Profiling Scoring Criterion (NPSC).Results: Between October 2014 and November 2015, 1357 eligible shoppers were randomly assigned to TLL (n = 459), HSR (n = 443), or NIP (n = 455) labels. Overall difference in the mean transformed NPSC score for the TLL group compared with the NIP group was -0.20 (95% CI: -0.94, 0.54; P = 0.60). The corresponding difference for HSR compared with NIP was -0.60 (95% CI: -1.35, 0.15; P = 0.12). In an exploratory per-protocol analysis of participants who used the labeling intervention more often than average (n = 423, 31%), those who were assigned to TLL and HSR had significantly better NPSC scores [TLL compared with NIP: -1.33 (95% CI: -2.63, -0.04; P = 0.04); HSR compared with NIP: -1.70 (95% CI: -2.97, -0.43; P = 0.01)]. Shoppers who were randomly assigned to HSR and TLL also found the labels significantly more useful and easy to understand than the NIP (all P values <0.001).Conclusions: At the relatively low level of use observed in this trial, interpretive nutrition labels had no significant effect on food purchases. However, shoppers who used interpretive labels found them to be significantly more useful and easy to understand, and compared with frequent NIP users, frequent TLL and HSR users had significantly healthier food purchases. This trial was registered at the Australian New Zealand Clinical Trials Registry (https://www.anzctr.org.au/Trial/Registration/TrialReview.aspx?id=366446&isReview=true) as ACTRN12614000644662.
