RESUMO

Gluten-related disorders are treated with a gluten-free diet. The "basic food basket" (BFB) consists of a list of basic foods consumed by low-income groups in society, including those lowest-cost versions within each food category. To evaluate the cost, availability, and nutritional quality of the BFB and gluten-free BFB (GF-BFB), foods were photographed, registering their cost, availability, and nutritional characteristics, in high quality and mid-range supermarkets, wholesalers, health shops, and corner shops, matching each regular BFB product with a gluten-free equivalent. Of the 1177 potential products, the selection of lowest-cost foods yielded 55 and 47 products (BFB and GF-BFB, respectively). Breads/cereals and drinks showed the highest differences (279% and 146%, respectively) while meats and sausages showed the lowest ones (18.6%). The GF-BFB cost represents 30.1% of the minimum wage, which covers the cost of 5.2 and 3.3 of the BFB and GF-BFB per month, respectively. Availability ranged between 22.7 and 42.4%. Lower availability was associated with poorer nutritional quality in the GF-BFB, which provides 5% less energy, 26% more fat, and 25% less protein than the BFB. Only 47% of gluten-free products declared their "gluten-free" condition. The results strongly suggest that the GF-BFB must be redesigned to be both gluten-free and nutritionally adequate.

RESUMO

Effective ways to promote healthful food intake in rural areas are understudied. The paper evaluated whether a two-component, in-store intervention designed to encourage healthy food purchases was associated with improved healthfulness scores of food items purchased by shoppers in rural food deserts. One component introduced a point-of-sales label that assigned a single numerical score to each food item facilitating direct comparisons of the product's nutrition with those of other products shelved around it. The other component was a one-day nutrition education workshop promoted within the store. Interventions took place in 2015 at two stores in rural counties in the U.S. Midwest. Four stores in similar communities were selected as the control group. We applied a difference-in-difference model to estimate changes in the healthfulness of food items purchased attributable to the intervention among shoppers at the treatment stores (n = 486) and control stores (n = 10,759) using store transaction data. Healthfulness of food items was measured in terms of food scores published by the Environmental Working Group on a 1-10 scale. Both components had minimal impacts on the scores, although 0.2 and 0.1 points increases in the score per item and score per dollar were statistically significant at the 1% level respectively. A year after the intervention, these small effects of the intervention further diminished compared to the immediately after implementation. Results suggest the average effects of intervention across the study communities had limited practical significance but benefited some rural residents who were exposed to the intervention.

RESUMO

OBJECTIVE: To measure the effects of health-related food taxes on the environmental impact of consumer food purchases in a virtual supermarket. DESIGN: This is a secondary analysis of data from a randomised controlled trial in which participants were randomly assigned to a control condition with regular food prices (n 152), an experimental condition with a sugar-sweetened beverage (SSB) tax (n 131) or an experimental condition with a nutrient profiling tax based on Nutri-Score (n 112). Participants were instructed to undertake their typical weekly grocery shopping for their households. Primary outcome measures were three environmental impact indicators: greenhouse gas (GHG) emissions, land use and blue water use per household per week. Data were analysed using linear regression analyses. SETTING: Three-dimensional virtual supermarket. PARTICIPANTS: Dutch adults (≥ 18 years) who were responsible for grocery shopping in their household (n 395). RESULTS: GHG emissions (-7·6 kg CO2-eq; 95 % CI -12·7, -2·5) and land use (-3·9 m2/year; 95 % CI -7·7, -0·2) were lower for the food purchases of participants in the nutrient profiling tax condition than for those in the control condition. Blue water use was not affected by the nutrient profiling tax. Moreover, the SSB tax had no significant effect on any of the environmental impact indicators. CONCLUSIONS: A nutrient profiling tax based on Nutri-Score reduced the environmental impact of consumer food purchases. An SSB tax did not affect the environmental impact in this study.

RESUMO

Unhealthy food choices and consumption, coupled with sedentary lifestyles among consumers, intensify public health concerns regarding the quadruple disease burden, despite Primary Health Care (PHC) policy. However, the current relationship between consumer knowledge about healthy foods and following a healthy lifestyle needs to be explored. Our study, therefore, aimed to determine the association between consumers' subjective and objective knowledge about healthy foods and various healthy lifestyle choices. A cross-sectional survey was conducted among employed consumers (N = 157) from South African corporate settings. We used structural equation modelling (SEM) to determine associations between subjective and objective knowledge about healthy foods and healthy lifestyle choices. Our findings showed that most participants scored high on making healthy lifestyle choices relating to avoiding smoking (69.5%) and limiting drinking alcohol (68.7%) but less so for food and sleep (44.4%) while neglecting exercise, relaxation (13.7%), and choices that require dedicated effort (25.2%). On average, participants had high levels of subjective (mean = 3.59; 5-point Likert scale) knowledge and objective knowledge about healthy foods (88.4-95.9% correct responses). However, their objective knowledge about weight and cholesterol had severe deficiencies (36.7%). SEM confirmed an association between subjective knowledge and most healthy lifestyle choice categories, while income contributed to dedicated effort lifestyle choices. By contrast, objective knowledge did not associate with such choices. Our structural model suggests that subjective knowledge about healthy foods contributes to healthy lifestyle choices. Therefore, subjective knowledge and the objective knowledge deficiencies we identified among corporate consumers can serve as a valuable starting point for informed education to promote PHC policy and healthy lifestyle choices.

RESUMO

BACKGROUND: Nutrition and health claims influence consumer purchasing. Claims include content claims, which refer to the amount of a nutrient contained in a product, and health claims, which refer to health benefits of foods or nutrients in a product. Products that display a health claim must meet the Nutrient Profiling Scoring Criterion (NPSC). The present study aimed to explore consumer perceptions of content claims used on food and beverage labelling and advertisements. METHODS: Semi-structured focus groups were conducted with Australian consumers. Analysis involved an inductive, reflexive approach to thematic analysis. RESULTS: Six focus groups involving 26 participants were conducted. Four main interconnected themes were generated: (1) complex factors influence food choice; (2) content claim scepticism; (3) the difference between content and health claims is unclear; and (4) the regulation of content claims is not common knowledge. Content claims were used, although generally viewed through a lens of scepticism and mistrust, and seen as a promotional tool for the food industry. Product complexity appeared to increase content claim use as a result of consumer uncertainty of the content of complex products, such as ultraprocessed foods. Most participants were aware that content and health claims were in some way regulated. Overall, they did not know further detail, including the relevant regulatory body. CONCLUSIONS: For content claims to support the consumer they need to be accurate and their use limited to healthier foods. This can be achieved by requiring products with content claims to meet NPSC thresholds, as required for products making health claims.

RESUMO

BACKGROUND: Changes to prescribing policies in England have restricted or stopped access to gluten-free food on prescription for people with coeliac disease in some geographical areas. The present study aimed to explore the impact of these changes on the affordability and obtainability of gluten-free foods for adults with coeliac disease. METHODS: Semi-structured qualitative interviews (n = 24) were conducted with people with coeliac disease living in areas where prescriptions for gluten-free foods were no longer available, were restricted or followed national guidelines. Interviews explored the impact of gluten-free prescribing changes on the affordability and obtainability of gluten-free food, as well as dietary adherence. RESULTS: All participants considered gluten-free substitute foods to be expensive. Participants felt the availability of gluten-free foods has improved over time, also acknowledging some challenges remain, such as limited local availability. For most, the withdrawal of prescriptions had minimal impact requiring small adjustments such as reducing the quantity of foods obtained. However, greater challenges were faced by those less mobile, permanently sick or disabled and/or on lower incomes. CONCLUSIONS: The majority of participants affected by the withdrawal of prescriptions were able to adapt to cope with these changes. However, participants with mobility issues, who are permanently sick or disabled and/or on lower incomes were struggling to afford and obtain gluten-free substitute foods from elsewhere. The withdrawal of prescriptions may further widen health inequalities. Further research should focus on the long-term impacts of prescription withdrawal for the vulnerable groups identified.

RESUMO

The purpose of this research was to apply DINESERV to a food brand: Shake Shack. Six sub-dimensions (e.g., taste, healthiness, employee service, price fairness, ambience, and convenience) were adopted. This study used brand trust and brand loyalty to explain attributes. This research additionally assessed the moderating impact of healthiness on the relationship between taste and brand loyalty. For data collection, this study used Amazon Mechanical Turk. The main instrument of this research is a survey. The number of valid observations was 353. Confirmatory factor analysis and a correlation matrix were used to ensure the convergent and discriminant validity of measurement items. Structural equation modeling was employed for hypothesis testing. Plus, Hayes process macro model 1 was employed to test the moderating effect of healthiness. Results indicated that brand trust was positively associated with taste (p < 0.05), employee service (p < 0.05), and ambience (p < 0.05), while brand loyalty was positively associated with taste (p < 0.05), healthiness (p < 0.05), price fairness (p < 0.05), ambience (p < 0.05), and brand trust (p < 0.05). However, the convenience of casual restaurants appeared as a non-significant attribute to account for both brand trust and brand loyalty. The results also revealed that healthiness negatively moderates the relationship between taste and brand loyalty (p < 0.05). This study sheds light on the literature by demonstrating the accountability of DINESERV to casual dining customer behavior. Also, this research presents information for the assistance of brand management in the domain of casual dining sector.

RESUMO

PURPOSE: One-capsule, once-daily valbenazine is approved for tardive dyskinesia and under evaluation for chorea associated with Huntington's disease, conditions in which patients often experience dysphagia. In vitro studies were conducted to assess the suitability of crushing the contents of valbenazine capsules (40 and 80 mg) for mixing with soft foods or liquids or administration via a gastrostomy tube (G-tube). METHODS: In study 1, the dissolution of whole valbenazine capsules and crushed capsule contents were measured serially for 1 hour. In study 2, valbenazine recovery was evaluated after crushed contents were mixed with soft foods, buffer solutions (pH range, 1.2-6.8), and fed-state simulated gastric fluid. In study 3, valbenazine recovery was evaluated after crushed contents were dispersed in water and delivered via a G-tube. In studies 2 and 3, acceptable valbenazine recovery was 90% to 110%. FINDINGS: Study 1 indicated rapid and complete drug release for whole valbenazine capsules and crushed capsule contents, with similar release at 10 minutes (whole, 94%-99%; crushed, 98%-100%) and 60 minutes (whole, 101%-103%; crushed, 101%-102%). Study 2 found acceptable valbenazine recovery within 2 hours of adding crushed capsule contents to tested foods, buffers, or fed-state simulated gastric fluid (recovery, 92%-102%). Study 3 found acceptable valbenazine recovery when crushed contents were added to cold or hot water and delivered via G-tube, with a water cup rinse to capture residual contents (recovery, 91%-97%). IMPLICATIONS: These studies indicate the potential viability of valbenazine formulation(s) that can be added to soft foods or liquids or delivered via G-tube. Such formulations will be important for individuals who require treatment with a vesicular monoamine transporter 2 inhibitor but cannot swallow whole pills.

RESUMO

Sugar, salt, and fat content in processed products are important concerns for consumers. Hence, alternative "healthy" versions of conventional foods such as chocolate, potato chips, and yogurt are offered. This work aimed to define the emotional response of consumers from different cultural backgrounds (Spain vs. Brazil) evoked by healthier versions of conventional products and the relationship between hedonic responses and health consciousness. A total of 186 Brazilian and 152 Spanish consumers participated in this online cross-cultural study. Participants answered a Health Consciousness Questionnaire and an emotional check-all-that-applies questionnaire using picture stimuli of conventional chocolate, potato chips, and yogurt and their healthier versions with less sugar, salt, and fat content, respectively. The Brazilians' emotional responses were more diverse for all stimuli compared to the Spaniards'. However, participants from both cultures rated an average of "slightly agree" on the health consciousness scale; a higher level of consumption, liking, and willingness to buy; and a higher frequency of positive emotional terms for the stimuli of conventional products compared to their healthier versions. A higher frequency of evocation of "active" is strongly associated with higher levels of health consciousness. Strategic actions by the food industry and government must consider cultural, emotional, and health-conscious factors to encourage the consumption of healthier foods. PRACTICAL APPLICATION: Food manufacturers can use the information obtained from this study to create healthier versions of their products that appeal to consumers' emotional responses and health consciousness levels. The findings can assist in designing strategic actions to promote healthier food consumption by emphasizing the benefits of healthier food choices and making them more appealing to consumers. The methodology employed in this study can also be applied to further studies aimed to assess emotional responses to food stimuli across different cultures.

RESUMO

Sensory and consumer research performs a pivotal role in gluten-free (GF) food research and development due to consumer dissatisfaction about currently available products, despite the continued growth of this market and promising research developments. Nowadays, almost half of the original articles about GF products include sensory analysis. A current overview is needed to help both food scientists and industry indentify current trends and forward-looking approaches. This current review has gathered information concerning sensory and consumer research for GF bakery and pasta products, from studies published in the last decade, and then discusses future challenges in the light of recent advances. Among the promising approaches, projective techniques that collect data using social media can provide quick, spontaneous and direct opinions from GF consumers. They can also be used to evaluate trends and cross-cultural or global insights. Participatory methods have highlighted the importance of label information and may further explore the behavior of GF consumers in more realistic environments, as well as to evaluate the intrinsic GF food factors in GF consumer opinions, emotions, behavior and choices. This review details current issues occurring in sensory analysis of GF products, which still need to be resolved. The combination of affective and analytical methods allows for a better characterization of the samples and such sensory analysis of GF products in the future could guide product development and quality control, overcoming technological, nutritional, and shelf-life issues.

RESUMO

INTRODUCTION: This observational study assessed the introduction of a comprehensive healthy food and drink policy across 13 community organisation managed aquatic and recreation centres in Victoria, Australia, and the associated changes on business outcomes, and the healthiness of purchases. The policy, based on state government guidelines, mandated that food and drink availability be based on healthiness classification: 'red' (limit) <10%, and 'green' (best choice) >50%, and the remainder 'amber' (choose carefully). METHODS: Six years of monthly sales data were split into three periods, prior to (1/01/2013-31/12/2014), during (1/01/2015-31/12/2016) and post (1/1/2017-31/12/2018), policy implementation. Using point-of-sale data, food and drink nutrient content, and state guidelines, items were classified as 'red'/'amber'/'green'. Linear models with Newey West standard errors were fitted to compare the mean value of outcomes between post- to pre-policy implementation periods, for each outcome and centre; and were pooled using random effect meta-analyses. RESULTS: Comparing post- to pre-policy implementation periods, total food sales did not change (mean percentage difference: -3.2% (95% confidence interval (CI) -21% to 14%), though total drink sales declined -27% (CI -37% to -17%). The mean percentage of 'red' foods sold declined by -15% (CI -22% to -7.7%), 'amber' food sales increased 11% (CI 5.5% to 16%). 'Green' food sales did not change (3.3%, CI -1.4% to 8.0%). The mean percentage of 'red' drinks sold declined -37% (CI -43% to -31%), 'amber' and 'green' drink sales increased by 8.8% (CI 3.6% to 14%) and 28% (CI 23% to 33%), respectively. The energy density and sugar content (percentage of total weight/volume) of both food and drinks decreased. CONCLUSIONS: This study has shown that the implementation of a policy to improve the health of retail food environments can result in a shift towards healthier purchases. Sales revenue from foods did not decline, though revenue from drinks did, indicating future research needs to explore mitigation of this.

RESUMO

Accurately and high-thoroughly screening illegal additives in health-care foods continues to be a challenging task in routine analysis for the ultrahigh performance liquid chromatography-high resolution mass spectrometry based techniques. In this work, we proposed a new strategy to identify additives in complex food matrices, which consists of both experimental design and advanced chemometric data analysis. At first, reliable features in the analyzed samples were screened based on a simple but efficient sample weighting design, and those related to illegal additives were screened with robust statistical analysis. After the MS1 in-source fragment ion identification, both MS1 and MS/MS spectra were constructed for each underlying compound, based on which illegal additives can be precisely identified. The performance of the developed strategy was demonstrated by using mixture and synthetic sample datasets, indicating an improvement of data analysis efficiency up to 70.3 %. Finally, the developed strategy was applied for the screening of unknown additives in 21 batches of commercially available health-care foods. Results indicated that at least 80 % of false-positive results can be reduced and 4 additives were screened and confirmed.

RESUMO

Fiscal tools-taxes and/or subsidies-are increasingly used to address diet-related health problems. However, some studies have found that these tools are markedly more effective if attention is drawn to the tax or subsidy, suggesting that the price change alone may go unnoticed in the complex food environments that consumers face. Interventions that prompt individuals to consider health during choice show promise for promoting healthy food choices in both simple laboratory settings and complex, real-world markets. In this pre-registered study, I examine the impact of dietary fiber health prompts and/or dietary fiber subsidies on the per-serving fiber content of foods chosen, the documented set of products considered, and (self-reported) nutrition information use by participants in an online supermarket setting. Participants were randomized to one of four conditions: 1) control, 2) subsidy, 3) fiber prompt, and 4) fiber prompt + subsidy. Results show that both the prompt and prompt + subsidy conditions significantly increase fiber content of foods chosen (with the latter having a larger effect). While all three interventions influence the probability of using nutrition information during food choice and affect the set of products that respondents consider relative to the control condition, the effects were larger for the prompt and prompt + subsidy conditions. A multiple mediation analysis illustrates that both direct and indirect (through the set of products considered and the use of fiber information during choice) pathways lead to the significant overall increase in fiber content of selected foods.

RESUMO

INTRODUCTION: Australian healthy food baskets are typically modelled off the Government Guidelines for healthy eating. However, these baskets have not been updated recently, nor has there been a Mediterranean Diet basket developed for an Australian population despite research suggesting high adherence is possible and subsequent health benefits observed. Food baskets typically only present the nutrition profile or the cost of a basket, seldom both. METHODS: Baskets were developed based on the Australian Guide to Healthy Eating, The Mediterranean Diet and typical Australian dietary intake (Western Diet). Four reference families were created based on data from Australian censuses and population statistics. Seven-day meal plans for reference families were entered into Foodworks software and aimed to meet 100% of nutrition and energy requirements. Basket costs were calculated from Coles Australia online. RESULTS: The AGHE basket met all NRVs except for VLCN3 for the 7-year-old male (73% adequate intake). The Mediterranean Diet met all NRVs except zinc (44-year-old male) ranging from 98 to 257% of the RDI. The Western Diet failed to meet NRVs for numerous nutrients. The MedDiet baskets were generally cheaper ($78 for a one-person household to $285 for a four-person household) than AGHE and Western Diet. DISCUSSION: Meeting nutrition requirements over seven days for zinc can be challenging for males. Fortified products provide an opportunity to improve nutrient profile; however, nutrient intake should equilibrate over time. Further, cost saving strategies can increase affordability. This research suggests a MedDiet is not more costly than a typical Western Diet or healthy AGHE diet.

RESUMO

Child malnutrition is an endemic public health problem in Africa. Infants are supposed to receive complementary foods from about 6 months onwards, as breastmilk alone no longer provide adequate nutrients. Commercially available complementary foods (CACFs) form an important part of baby foods in developing countries. However, systematic evidence on whether they really meet optimal quality specifications for infant feeding is limited. Some CACFs commonly used in Southern Africa and other parts of the world were investigated to establish if they meet optimal quality standards for protein and energy content, viscosity, and oral texture. For the energy content, most CACFs for 6-24-month-old children both in the dry and ready-to-eat forms (range: 372.0-1816.0 kJ/100 g), were below Codex Alimentarius guidelines. The protein density of all CACFs (0.48-1.3 g/100 kJ) conformed with Codex Alimentarius requirements, but some (33%) were below the minimum World Health Organization (World Health Organization. Regional Office for Europe (2019a). Commercial foods for infants and young children in the WHO European region) target of 0.7 g/100 kJ. Most CACFs had high viscosity values even at high shear rate of 50 s-1 , and were too thick or thick, sticky, grainy, and slimy, which may limit nutrient intake in infants, potentially causing child malnutrition. There is a need to improve the oral viscosity and sensory texture of CACFs for better nutrient intake by infants.

RESUMO

Low-income families, especially those who reside in food deserts, face significant systemic barriers regarding their ability to access affordable and nutritious food. The food behaviors exhibited by low-income families are a reflection of the shortcomings of the built environment and conventional food system. Policy and public-health initiatives to improve food security have, thus far, failed to deliver interventions that simultaneously address multiple pillars of food security. Centering the voices of the marginalized and their place-based knowledge may result in the development of food-access solutions that are a much better fit for the population that they intend to serve. Community-based participatory research has emerged as a solution to better meet the needs of communities in food-systems innovation, but little is known about the extent to which direct participation improves nutritional outcomes. The purpose of this research is to answer the following question: how can food-access solutions authentically engage marginalized community members in food-system innovation, and if participation is related to changes in their food behaviors, how is it related? This action research project leveraged a mixed-methods approach to analyze nutritional outcomes and define the nature of participation for 25 low-income families who reside in a food desert. Our findings suggest that nutritional outcomes improve when major barriers to healthy food consumption are addressed, for example, time, education, and transportation. Furthermore, participation in social innovations can be characterized by the nature of involvement as either a producer or consumer, actively or inactively involved. We conclude that when marginalized communities are at the center of food-systems innovation, individuals self-select their level of participation, and when primary barriers are addressed, deeper participation in food-systems innovation is associated with positive changes in healthy food behaviors.

RESUMO

Craving for high-calorie foods predicts consumption of high-calorie foods thereby contributing to unhealthy eating habits and, potentially in the long term, to the development of overweight, obesity, and eating disorder pathology. Thus, effective interventions tackling craving for unhealthy foods and motivating healthy eating behavior are needed. This initial study tested if an experimental mental imagery procedure could induce craving for healthy foods and increase the motivation to eat healthily. Participants (N = 82) were randomized to either a healthy craving mental imagery condition or to a neutral mental imagery control condition. Craving for healthy foods and motivation to eat healthily was assessed before and after the experimental manipulation via self-report. A (disguised) food choice for healthy versus unhealthy food was added as a behavioural measure at the end of the experiment. Repeated measures of variance analyses with time (pre vs. post experimental manipulation) and condition (healthy craving mental imagery versus neutral mental imagery) yielded significant interactions for healthy craving and motivation to eat healthily: Post-hoc tests showed that craving for healthy foods and motivation to eat healthily increased significantly after the experimental manipulation in the healthy craving mental imagery condition, but not in the neutral mental imagery condition. Results of this initial study suggest that an experimental mental imagery induction of craving for healthy food leads to an increase in healthy craving and motivation to eat healthily. Further experimental research is needed to rule out priming effects, to test the underlying mechanisms of this effect, and evaluate the potential of this mental imagery procedure in a clinical context.

RESUMO

BACKGROUND: Andean purple maize (APM) is an ancient crop widely used as a natural coloring in traditional Peruvian cuisine. However, it has been little explored within the food industry. The present study assessed how APM impacts on techno-functional properties and sensory acceptance of breakfast cereals. Extruded samples formulated with 100, 75, 50, and 25% APM, and complemented with yellow corn grits (YCG), were analyzed for their techno-functional and sensory properties. RESULTS: Increases in bulk density, as well as reduction in the expantion and porosity were observated for extrudates containing ≥ 50% APM, accompanied by an increase in purple color intensity. Increase in milk absorption index, reduction in milk solubility index and decrease in cereal hardness with increase in APM were also observed. Despite this, APM extented the cereal bowl-life. High sensory scores of overall liking (6) and color (7) were obtained for extruded formulations containing ≥ 50% APM and low values for extrudates with 25% APM. Aroma, flavor, and texture scores did not present significant differences. CONCLUSION: APM is an ingredient with the potential to be used to produce breakfast cereals since it improves their techno-functional characteristics and sensory acceptance, at the same time, it leads to the production of healthy, nutritious, and sustainable food. © 2022 Society of Chemical Industry.

RESUMO

Nature may have the answer to many of our questions about human, animal, and environmental health. Natural bioactives, especially when harvested from sustainable plant and food sources, provide a plethora of molecular solutions to nutritionally actionable, chronic conditions. The spectrum of these conditions, such as metabolic, immune, and gastrointestinal disorders, has changed with prolonged human life span, which should be matched with an appropriately extended health span, which would in turn favour more sustainable health care: "adding years to life and adding life to years". To date, bioactive peptides have been undervalued and underexploited as food ingredients and drugs. The future of translational science on bioactive peptides-and natural bioactives in general-is being built on (a) systems-level rather than reductionist strategies for understanding their interdependent, and at times synergistic, functions; and (b) the leverage of artificial intelligence for prediction and discovery, thereby significantly reducing the time from idea and concept to finished solutions for consumers and patients. This new strategy follows the path from benefit definition via design to prediction and, eventually, validation and production.

RESUMO

The composition and quality of food rations and the intake of nutrients with the diet are undoubtedly reflected in our health. In order to help the consumer choose the right food product, food manufacturers use front-of-pack labels, which are designed to convey concise information about the nutritional value of the product. Such labels include the Nutri-Score system. In this paper, we have critically analyzed this system. As the available data indicate, this system does not take into account a number of factors that affect the quality of a food product, including the size of the package, the contents of vitamins, minerals, and other selected health-promoting ingredients, the degree of processing, or the fatty acid profile of the product, and it discriminates against regional products, organic products, and juices and nectars. This system, although intuitive and created with good intentions, still has quite a few flaws that must be addressed before it can be considered to correctly indicate the nutritional value of food products.
