RESUMO

OBJECTIVES: Based on the legal framework regulating the advertisement of food supplements in the EU, the aim of this article is to analyse the relationship between the presence of endorsers, the different types of health-related claims (H-RCs) and product content information. STUDY DESIGN: We applied a quantitative approach based on the content analysis of all radio spots broadcast throughout 2017 on full-service radio stations in Spain. METHODS: A corpus of 10,556 radio spots was obtained of the three radio stations with the highest audience levels (165 without repetitions). We incorporated data on the accumulated broadcast frequencies to supplement the content analysis specific to each radio spot with its weight in relation to the overall advertising discourse. We developed a coding scheme to assess the type of endorser, the types of H-RCs, and the product content information. RESULTS: Results show that European directives are breached in different ways. Healthcare experts prevail in disease claims, although they are prohibited. Celebrities are the most widely used endorsers (25%) in the function and reduction of disease risk claims. In addition, although these types of claims require substantiation by authorised ingredient, 73% of H-RCs lack this information. CONCLUSIONS: The high presence of illicit H-RCs and endorsers, such as physicians, and the omission of compulsory product information suggest that public administrations must apply stricter monitoring and sanctioning mechanisms to dissuade advertisers from further breaches of the law and to protect consumers. Implications for public health policy are made.

RESUMO

ANTECEDENTES Y OBJETIVOS: la normativa que regula la inclusión de alimentos para usos médicos especiales (ADUME) entre las prestaciones del Sistema Nacional de Salud (SNS) fue elaborada hace unos 15 años, si bien la nutrición enteral domiciliaria (NED) se comenzó a regular en 1998. La evolución de las características técnicas de los ADUME justifica un análisis de la actual normativa y la consideración de posibles modificaciones que permitan la incorporación de avances tecnológicos. MATERIAL Y MÉTODOS: reuniones estructuradas siguiendo la metodología del grupo focal, con expertos en su mayoría médicos (91 %), mujeres (55 %) y especialistas hospitalarios en disciplinas relacionadas con la nutrición (73 %) de 8 hospitales y 6 comunidades autónomas. Previamente, los participantes recibieron 4 documentos resumen de diferentes aspectos técnicos de la regulación sobre ADUME en España. Se transcribió de forma anonimizada el audio de las reuniones y se codificó su contenido en 9 códigos: 1) problemática y regulación; 2) beneficios clínicos y evidencia de eficacia o efectividad; 3) indicaciones clínicas; 4) contexto internacional y comparaciones con otros países; 5) impacto presupuestario; 6) coste-efectividad; 7) riesgos y motivos para mantener la regulación actual; 8) propuestas de avance, factibilidad y aspectos que dificultan la implementación; y 9) otros temas. RESULTADOS: los grupos señalaron la necesidad de modificar aspectos regulatorios relacionados con la exclusión de financiación de las fórmulas de densidad calórica superior a 2,1 kcal/ml, la exclusión de la financiación de los ADUME obtenidos total o parcialmente a partir de alimentos ordinarios, la preferencia por la alimentación por sonda y la exclusividad de la financiación de fórmulas completas para los ADUME que se empleen por vía oral como complemento de una ingesta insuficiente. CONCLUSIONES: sobre la base del desarrollo tecnológico y la aplicación clínica de los ADUME en los últimos años, el SNS debería actualizar la regulación de la financiación de estos productos. La mayor parte de estos cambios no implican incremento del gasto si se mantienen las condiciones actuales en cuanto a indicaciones y precios máximos


BACKGROUND AND OBJECTIVES: the legislation currently regulating the inclusion of Food for Special Medical Purposes (FSMP) among the benefits of the National Health System (SNS) was made approximately 15 years ago. The evolution of the technical characteristics of the FSMP justifies an analysis of the current regulation and the consideration of possible regulatory modifications that would allow the incorporation of the progress achieved. MATERIAL AND METHODS: four successive focus groups of experts, mostly doctors (91%), hospital specialists in disciplines related to nutrition (73%), from 8 different hospitals and 6 autonomous communities. Previously, 4 documents summarizing different technical aspects of the regulation on FSMP in Spain were sent to the participants. The audio of the meetings was transcribed anonymously and its content was codified. RESULTS: the contents of the focus groups were grouped into 9 codes: 1) problems and regulation; 2) clinical benefits and evidence of efficacy or effectiveness; 3) clinical indications; 4) international context and comparisons with other countries; 5) budgetary impact; 6) cost-effectiveness; 7) risks and reasons for maintaining current regulation; 8) proposals for progress, feasibility and aspects that make implementation difficult; and 9) other issues. CONCLUSIONS: based on the technological development and clinical application of the FSMP carried out in recent years, an update of the regulation of these products can be proposed for financing by the National Health System in Spain. Most of these changes do not imply an increase in expenditure if current conditions regarding indications and maximum prices are maintained

RESUMO

In an effort to elucidate an aspirational vision for the food system and explore whether the characteristics of such a system inadvertently set unattainable standards for low-wealth rural communities, we applied discourse analysis to the following qualitative datasets: (1) interviews with food experts and advocates, (2) scholarly and grey literature, (3) industry websites, and (4) email exchanges between food advocates. The analysis revealed eight aspirational food system discourses: production, distribution, and infrastructure; healthy, organic, local food; behavioral health and education; sustainability; finance and investment; hunger relief; demand-side preferences; romanticized, community led transformations. Study findings reveal that of eight discourses, only three encompass the experiences of low-wealth rural residents. This aspirational food system may aggravate the lack of autonomy and powerlessness already experienced by low-wealth rural groups, perpetuate a sense of failure by groups who will be unable to reach the aspirational food vision, silence discourses that might question those that play a role in the inequitable distribution of income while sanctioning discourses that focus on personal or community solutions, and leave out other policy-based solutions that address issues located within the food system. Further research might explore how to draw attention to silenced discourses on the needs and preferences of low-wealth rural populations to ensure that the policies and programs promoted by food system experts mitigate poor diets caused by food insecurity. Further research is needed to inform policies and programs to mitigate food insecurity in low-wealth rural populations.

RESUMO

PURPOSE: The purposes of the study were to estimate the effect of Healthy, Hunger-Free Kids Act of 2010 (HHFKA) implementation on dietary quality of all U.S. school-aged children and adolescents and examine whether those effects differed by the demographic group. METHODS: We used survey regression on 2007-2016 National Health and Nutrition Examination Survey data to estimate the proportion of energy intake from school foods and the association between school food intake and dietary quality, before and after HHFKA passage/implementation. To account for demographic changes in the U.S. population over time, inverse probability weighting was used. The product of the proportion of energy from school foods and the association between school food intake and dietary quality estimated the effect of HHFKA implementation on dietary quality. RESULTS: School food intake quantity remained stable during the study period. HHFKA implementation improved students' dietary quality by 4.3 Healthy Eating Index-2010 points (95% confidence interval: 2.5, 6.1) on days when school foods were eaten and by 1.3 Healthy Eating Index-2010 points (95% confidence interval: 0.73, 1.8) averaged over all days annually. CONCLUSIONS: HHFKA implementation improved the total dietary quality of U.S. school students. U.S. students would benefit from eating school meals in the post-HHFKA era, and HHFKA regulations should not be relaxed.

RESUMO

En el siguiente trabajo de investigación se realiza un análisis del patrón alimentario de los habitantes de la ciudad de Alcalá de Henares a través de la pirámide invertida, que lo diferencia de la pirámide estándar ya existente. Como metodología, se realiza un estudio observacional de corte transversal, en el que se recogen los datos acerca del patrón alimentario a través de cuestionarios vía telefónica, presencial u online. Posteriormente, se clasifican estos datos por tres variables distintas como son edad, sexo y sentimiento de soledad, concluyendo que existen marcadas diferencias respecto al patrón alimentario. Se observa que las personas de entre 45-64 años consumen los distintos grupos de alimentos de una forma más adecuada que los adultos más jóvenes; respecto al sexo, las mujeres llevan a cabo un patrón alimentario más saludable desde edades tempranas respecto de los hombres; y respecto a las personas con sentimiento de soledad, se evidencia una mayor tendencia a peores patrones de consumo de alimentos en los grupos de personas que se sienten solas, generalmente adolescentes y adultos mayores. Se comprueba en el grupo de los universitarios jóvenes un consumo inferior de frutas, hortalizas y verduras, así como un aumento de su consumo en colegios; la evidencia de un mayor consumo de frutas y verduras por parte de las mujeres coincide con los datos disponibles a este respecto en el ámbito europeo; los grupos de personas que se sientan solas tienen asociados peores patrones alimentarios


In the following research work, an analysis is made of the eating pattern of the inhabitants of the city of Alcalá de Henares through the inverted pyramid, differentiating it from the existing standard pyramid. As a methodology, an observational cross-sectional study is carried out, in which data about the eating pattern is collected through questionnaires via telephone, in person or online. Later, these data are classified by three different groups such as age, sex, and people with feelings of loneliness; concluding that there are marked differences regarding the eating pattern, it is observed that people between 45-64 years old consume different food groups in a more adequate way than younger adults; Regarding sex, women carry out a healthier eating pattern from an early age compared to men; and regarding people with feelings of loneliness, a greater tendency to worse food consumption patterns is evident in the groups of people who feel lonely, generally adolescents and older adults. As a discussion, a lower consumption of fruits, vegetables and vegetables is evidenced in the group of young university students; an increase in the consumption of these in schools; European data coincidences regarding the higher consumption of fruits and vegetables in women; and worse patterns associated with groups of people who feel alone

RESUMO

The objective of Nutrimedia is to evaluate, based on the scientific evidence, the veracity of nutrition claims disseminated to the public by the media. In this article, we describe the methodology, characteristics and contents of this web-based resource, as well as its web traffic and media impact since it was launched. Nutrimedia uses a systematic process to evaluate common beliefs, claims from newspapers and advertising identified and selected by its research team, as well as questions from the public. After formulating a structured question for each claim, we conduct a pragmatic search, prioritizing guidelines and/or systematic reviews. We evaluate the certainty of the evidence using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach, and classify the veracity of each claim into seven categories (true, probably true, possibly true, possibly false, probably false, false, and uncertain). For each evaluation, we develop a scientific report, a plain language summary, a summary of findings table, and, in some cases, a video. From November 2017 to May 2019, we published 30 evaluations (21 were related to foods, six to diets, and three to supplements), most of which were triggered by questions from the public (40%; 12/30). Overall, nearly half of the claims were classified as uncertain (47%; 14/30). Nutrimedia received 47,265 visitors, with a total of 181,360 pages viewed. The project and its results were reported in 84 written media and 386 websites from Spain and 14 other countries, mostly from Latin America. To our knowledge, Nutrimedia is the first web-based resource for the public that evaluates the certainty of evidence and the veracity of nutrition claims using the GRADE approach. The scientific rigor combined with the use of friendly presentation formats are distinctive features of this resource, developed to help the public to make informed choices about nutrition.

RESUMO

Cannabis-infused "edibles" are a popular means of cannabis use, and the variety of edible food products available to consumers continues to grow. Although there has been much discussion on dose standardization, childproof packaging, and the prevention of overconsumption, the important topic of food safety has received less attention.We discuss potential food safety hazards associated with cannabis-infused edible food products, drawing on examples from Colorado, and describe edible-associated foodborne illness outbreaks and other contamination events.It is important for public health agencies, particularly environmental health and enteric disease programs, to be familiar with the cannabis industry, including regulatory partners, signs and symptoms of cannabis ingestion, the scope of edible products sold and consumed, and the food safety risks unique to cannabis products.

RESUMO

PURPOSE OF REVIEW: To discuss the overall and latest observations of the effect of diet, lifestyle, supplements, and some prescription heart healthy medications for prostate cancer prevention. RECENT FINDINGS: The concept of maximizing heart health to prevent aggressive prostate cancer continues to be solidified with the addition of more prospective observational and randomized controlled trial data. Heart healthy is prostate healthy, and heart unhealthy is prostate unhealthy. The primary goal of reducing the risk of all-cause and cardiovascular disease (CVD) morbidity and mortality also coincides with maximizing prostate cancer prevention. The obesity epidemic in children and adults along with recent diverse research has only strengthened the nexus between heart and prostate health. Greater dietary adherence toward a variety of healthy foods is associated with a graded improved probability of CVD and potentially aggressive cancer risk reduction. Preventing prostate cancer via dietary supplements should encourage a "first do no harm," or less is more approach until future evidence can reverse the concerning trend that more supplementation has resulted in either no impact or an increased risk of prostate cancer. Supplements to reduce side effects of some cancer treatments appear to have more encouraging data. A discussion of quality (QC) before utilizing any pill also requires attention. Medications or interventions that potentially improve heart health including statins, aspirin, and metformin (S.A.M.), specific beta-blocker medications, and even preventive vaccines are in general generic, low-cost, "natural," and should continue to garner research interest. A watershed moment in medical education has arrived where the past perception of a diverse number of trees seemingly separated by vast distances, in reality, now appear to exist within the same forest.

RESUMO

Federally mandated restrictions on food and beverage marketing to kids (M2K) have been re-introduced as a national public health priority in Canada by the newly elected government, following the failure to implement a similar policy first proposed in 2016. This study examined the extent to which Canadian packaged foods, including products already displaying M2K on the packaging, would be permitted to be marketed, based on the nutrient criteria for marketing restrictions defined by Health Canada (in December 2018) as part of the previous policy proposal. Products from the University of Toronto Food Label Information Program 2013 database (n = 15,200) were evaluated using Health Canada's published criteria: thresholds for sodium, sugars and saturated fats that products cannot exceed in order to be M2K. The proportion of products exceeding no thresholds (i.e., permitted to be M2K), the number of thresholds exceeded, and the proportion exceeding each individual threshold were calculated overall and in the subsample of products displaying M2K on the packaging (n = 747). Overall, 18.0% of products would be permitted to be M2K, versus 2.7% of products displaying M2K. Sodium was the most exceeded threshold overall (57.5% of products), whereas sugars was the most exceeded by products displaying M2K (80.1%). Only 4.7% of all products versus 10.4% of products displaying M2K exceeded all three thresholds. These results highlight the importance of reintroducing federal regulations restricting M2K in Canada and including marketing on product packaging in the regulatory scope.

RESUMO

BACKGROUND: The range of products stocked and their promotions in food retail outlets in healthcare settings can affect food choices by staff, patients and visitors. The innovative Scottish Healthcare Retail Standard (HRS) is a national mandatory scheme requiring all hospital food retail outlets to change the balance of food products stocked and their promotion to comply with nutritional criteria and promotional restrictions. The aim is to facilitate healthier food choices in healthcare settings. This study examined the implementation of HRS and the impact on foods stocked and promoted. METHODS: The study aimed to examine implementation process and changes to the retail environment in relation to food promotions and choice. A sample of hospital retail outlets (n = 17) including shops and trolley services were surveyed using a mixed methods design comprising: (a) structured observational audits of stock, layout and promotions (with a specific focus on chocolate and fruit product lines), and (b) face-to-face, semi-structured interviews with the shop manager or nominated members of staff (n = 32). Data were collected at Wave 1 (2016), at the beginning and during the early stages of HRS implementation; and Wave 2, 12 months later, after the HRS implementation deadline. RESULTS: All outlets, both commercial and not-for-profit, in the sample successfully implemented HRS. Implementation was reported to be more challenging by independent shop managers compared to chain store staff. Retail managers identified areas where more implementation guidance and support could have been provided. The number of chocolate product lines and promotions reduced substantially between Waves 1 and 2, but with no substantial increase in fruit product lines and promotions. Despite initial negative expectations of HRS's impact, managers identified some opportunities in the scheme and positive changes in the supply chain. CONCLUSIONS: Positive changes in food retail outlets occurred after hospital shops were required to implement HRS. By creating a consistent approach across hospital shops in Scotland, HRS changed the food retail environment for hospital staff, visitors and patients. HRS provides a regulatory template and implementation learning points for influencing retail environments in other jurisdictions and settings.

RESUMO

Given the absence of consensus on oral feeding of patients undergoing allogeneic hematopoietic transplantation, the ninth workshops of practice harmonization of the Francophone Society of Bone Marrow Transplantation and Cellular Therapy (SFGM-TC) allocated one session to address this topic, especially during the hospitalization. A questionnaire was sent to all SFGM-TC pediatric and adult centers in order to investigate oral feeding practices. The results demonstrated a large disparity among centers regarding oral feeding. Here, we report our recommendations regarding the oral feeding after allogeneic hematopoietic cell transplantation in terms of quality, quantity and bacterial authorized load.

RESUMO

Food and nutrition security can be supported by an urban garden. The present study comprises a critical reflection on the difficulty of producing food in urban gardens in Brazil and shows the potential of food production and the obstacles to its expansion. In addition, issues related to the agroecological management of gardens are addressed and suggestions are made to improve the proposed public policies. Urban gardens are multifunctional and have social, economic and environmental impacts. They are strategically important for supporting low-income families and urban development. Through urban gardens, diverse foods and quality foods can be produced for self-consumption. This review highlights the importance of generating detailed information on urban gardens in Brazil to support policies aimed at this sector. Long-term and multidisciplinary studies are needed to evaluate the relationship between food production in urban gardens and household food and nutrition security. This approach revealed a lack of information on the amount of food produced by Brazilians in their gardens and consumed by the household. In addition, there is little information on the management of production. There is a gap relating to the impact of food produced in urban gardens and the prevalence of food and nutrition security. © 2019 Society of Chemical Industry.

RESUMO

OBJECTIVE: To assess the accuracy of government inspection records, relative to ground observation, for identifying businesses offering foods/drinks. DESIGN: Agreement between city and state inspection records v. ground observations at two levels: businesses and street segments. Agreement could be 'strict' (by business name, e.g. 'Rizzo's') or 'lenient' (by business type, e.g. 'pizzeria'); using sensitivity and positive predictive value (PPV) for businesses and using sensitivity, PPV, specificity and negative predictive value (NPV) for street segments. SETTING: The Bronx and the Upper East Side (UES), New York City, USA. PARTICIPANTS: All food/drink-offering businesses on sampled street segments (n 154 in the Bronx, n 51 in the UES). RESULTS: By 'strict' criteria, sensitivity and PPV of government records for food/drink-offering businesses were 0·37 and 0·57 in the Bronx; 0·58 and 0·60 in the UES. 'Lenient' values were 0·40 and 0·62 in the Bronx; 0·60 and 0·62 in the UES. Sensitivity, PPV, specificity and NPV of government records for street segments having food/drink-offering businesses were 0·66, 0·73, 0·84 and 0·79 in the Bronx; 0·79, 0·92, 0·67, and 0·40 in the UES. In both areas, agreement varied by business category: restaurants; 'food stores'; and government-recognized other storefront businesses ('gov. OSB', i.e. dollar stores, gas stations, pharmacies). Additional business categories - 'other OSB' (barbers, laundromats, newsstands, etc.) and street vendors - were absent from government records; together, they represented 28·4 % of all food/drink-offering businesses in the Bronx, 22·2 % in the UES ('other OSB' and street vendors were sources of both healthful and less-healthful foods/drinks in both areas). CONCLUSIONS: Government records frequently miss or misrepresent businesses offering foods/drinks, suggesting caveats for food-environment assessments using such records.

RESUMO

This study aimed at determining the effect of aqueous ethanolic extracts from lemon balm, hyssop and nettle, and butylated hydroxyanisole (BHA) on properties of shortbread cookies. This was achieved by instrumental measurements of color and sensory properties of the cookies directly after baking and by determination of peroxide (PV) and p-anisidine (p-AnV) values, and specific extinction coefficients (K232 and K268 values) for fat extracted from the cookies stored for 3 months at room temperature. Increase of the herbal extracts' concentration from 0.02% to 0.2% in the cookies caused a reduction of L* (the brightness) and a* values (the red coordinate), while b* values (the yellow coordinate) increased when the cookies were enriched with lemon balm and nettle extracts. Among the cookies studied, those prepared with BHA and 0.1 and 0.2% addition of lemon balm extracts were characterized by the highest scores for aroma, taste, and overall acceptability. Incorporation of BHA and 0.02% hyssop extract into the cookies caused a decrease of PV values (the peroxide value) for fat extracted from the cookies after 3 months of their storage compared to a (control) sample without additives and produced the lowest K232 values. Changes in the p-AnV values for the fat samples studied occurred gradually and slowly during the storage and the obtained values were lower compared to the control sample. All of the studied fat samples also showed a higher ability to scavenge DPPH radicals than the control sample. Considering both PV and p-AnV values as indicators of fat oxidation, BHA protected fat extracted from cookies against oxidation better than the herbal extracts used.

RESUMO

A novel approach for battery-free food freshness monitoring is proposed and demonstrated in this study. The aim is to track the freshness of different sorts of food such as pork, chicken, and fish during storage. To eliminate the drawbacks of conventional food monitoring methods, which are normally based on measuring gas concentration emitted from food in a container, this approach measures the gradual increase in air pressure caused by the gas emission during storage. Additionally, we aim to design a smart sensor tag that can operate in fully passive mode without an external power source. To achieve this goal, near-field communication (NFC)-based energy harvesting is utilized in this work to achieve a self-powered operation of the sensor tag. To demonstrate the feasibility of the proposed method, experiments with the above-mentioned food were tested at room and refrigerated temperatures in 2 and 4 days, respectively. For each experiment, 200 g of the target food was placed in a 2-L container with the smart sensor tag. The experiments were conducted with both rigid and flexible containers to consider real food packaging environments. The air pressure inside the container was monitored as an indicator of food freshness by a sensitive pressure sensor on the smart sensor tag. The experimental results showed a remarkable increase in air pressure, which was able to be detected with high accuracy by the pressure sensor. The fabricated battery-free smart sensor tag is small (2.5 cm × 2.5 cm) and is capable of less than 1 mW of power consumption, which is ultra-low relative to other ordinary approaches that have a power consumption that normally surpasses 10 mW. The pressure value was used to classify food freshness into different levels on a mobile display to provide food freshness status using an NFC-enabled smartphone.

RESUMO

In Spain, 40% of children are overweight or obese. Television advertising is a widely acknowledged factor contributing to high-calorie food intake. This study longitudinally correlates some variables involved in childhood obesity prevention strategies in Spain. A mixed-methods approach was used. A quantitative analysis of audience data was conducted to determine the advertising campaigns most viewed by Spanish children from 2016 to 2018. The Nutri-score system was applied to determine the nutritional quality of the food advertised. A content analysis and a study of the discursive strategies used as an advertising ploy was undertaken. The results were examined in relation to the regulatory framework of the Spanish PAOS Code for the co-regulation of food advertising aimed at children. The study shows that Spanish advertising aimed at children mostly advertises very low nutritional value products. Moreover, these campaigns violate the PAOS Code in terms of the use of language in relation to the product, its benefits, and the appearance of popular characters. Our findings suggest a direct association between low nutritional value food ads and discursive strategies based on the intangible and extrinsic characteristics of these products. There remains the need for stricter legislation that takes into consideration the nutritional value of advertised foods and the language used in their hedonistic advertising.

RESUMO

Some nonthermal technologies have gained special interest as alternative approaches to thermal treatments. High pressure homogenization (HPH) and ultrasound (US) are two of the most promising approaches. They rely upon two different modes of action, although they share some mechanisms or ways of actions (mechanic burden against cells, cavitation and micronization, primary targets being the cell wall and the membrane, temperature and pressure playing important roles for their antimicrobial potential, and their effect on cells can be either positive or negative). HPH is generally used in milk and dairy products to break lipid micelles, whereas US is used for mixing and/or to obtain active compounds of food. HPH and US have been tested on pathogens and spoilers with different effects; thus, the main goal of this article is to describe how US and HPH act on biological systems, with a focus on antimicrobial activity, mode of action, positive effects, and equipment. The article is composed of three main parts: (i) an overview of US and HPH, with a focus on some results covered by other reviews (mode of action toward microorganisms and effect on enzymes) and some new data (positive effect and modulation of metabolism); (ii) a tentative approach for a comparative resistance of microorganisms; and (iii) future perspectives.
