In 1992, a pilot project for collecting information on the socioeconomic and nutritional status of children and their mothers as part of the early warning system was implemented in two villages in Kassala Province, Sudan. The objectives were to test the feasibility of local participation in socioeconomic and nutritional data collection, analysis and utilization;and to incorporate socioeconomic data into the food and nutrition information system, and examine its usefulness in early warning. The pilot project also included the introduction of new parameters such as adult anthropometry, i. e. body mass index of the mothers of the children seen, to monitor the nutritional status of both children and their mothers at the same time. This led to very interesting results which played a major role in determining the type of intervention needed

AbstractObjectiveThe current paper describes Diet In Nutrients Out (DINO), an integrated dietary assessment system incorporating dietary data entry and nutritional analysis within one platform for use in dietary assessment in small-scale intervention studies to national surveys.DesignDINO contains >6000 food items, mostly aggregated composites of branded foods, across thirty-one main food groups divided into 151 subsidiary groups for detailed reporting requirements, with fifty-three core nutrient fields.SettingMRC Human Nutrition Research (HNR), Cambridge, UK and MRC Keneba, Gambia.SubjectsDINO is used across dietary assessment projects at HNR and MRC Keneba.ResultsDINO contains macro- and micronutrients as well as additional variables of current research and policy interest, such as caffeine, whole grains, vitamin K and added sugars. Disaggregated data are available for fruit, vegetables, meat, fish and cheese in composite foods, enabling greater accuracy when reporting food consumption or assessing adherence to dietary recommendations. Portion sizes are categorised in metric and imperial weights, with standardised portion sizes for each age group. Regular reviews are undertaken for portion sizes and food composition to ensure contemporary relevance. A training programme and a checking schedule are adhered to for quality assurance purposes, covering users and data. Eating context questions are integrated to record where and with whom the respondent is eating, allowing examination between these factors and the foods consumed.ConclusionsAn up-to-date quality-assured system for dietary assessment is crucial for nutritional surveillance and research, but needs to have the flexibility to be tailored to address specific research questions.

As part of the Dutch Nutrition Surveillance System, cardiovascular risk factors and food consumption (24 h recall) as well as haematological, Fe and vitamin status (A, B6, C) were assessed in 126 Dutch boys aged 10–11 years (response 71 %). Body mass index (BMI) and the sum of four skinfolds were strongly associated (r0.85,P< 0.01) and 8% of the boys were overweight (BMI > 20.1 kg/m2). Elevated serum total cholesterol levels (> 4.4 mmol/l) were observed in 38 %; total cholesterol and low-density-lipoprotein-cholesterol levels were strongly associated (r0.88,P< 0.001). Intake of fat was high (38 % of energy) and too much fat was saturated (polyunsaturated: saturated 0.44, guideline: 0.5–1.0), whereas intake of carbohydrate (49% of energy) and dietary fibre was low. About 12% of the boys had insufficient Fe stores (plasma ferritin < 12.0 μg/l) and the mean Fe intake (9.0 mg/d) was below recommended daily allowance (10.0 mg/d). Plasma ferritin was, however, not associated with haematological indices and no frank anaemias were observed. No marginal values were observed for vitamins A, B6and C status. In conclusion, the main nutritional risks in boys aged 10–11 years are cardiovascular risk factors and Fe nutrition.

Full textAbstract:
The 2014 Health Canada’s Surveillance Tool, Tier System (HCST) is a nutrient profiling model developed to evaluate adherence of food choices to dietary recommendations. With the recent release of the nationally representative Canadian Community Health Survey-Nutrition (CCHS-N) 2015, this study used HCST to evaluate nutritional quality of the dietary intakes of Canadians in the CCHS-N. Dietary intakes were ascertained using 24-hour dietary recalls from Canadians adults ≥19 years (N = 13,605). Foods were categorized into four Tiers based on degree of adherence to dietary recommendations according to thresholds for sodium, total fat, saturated fats, and sugars. Tier 1 and Tier 2 represented “recommended foods”, Tier 3 represents foods to “choose less often”, and Tier 4 represented foods “not recommended”. Across all dietary reference intakes (DRI) groups, most foods were categorized as Tier 1 for Vegetable and Fruits (2.2–3.8 servings/day), Tier 2 for Grain Products (2.9–3.4 servings/day), Tier 3 for Milk and Alternatives (0.7–1 serving/day) or for Meat and Alternatives (1.1–1.6 servings/day). Consumption of foods from Tier 4 and “other foods” such as high fat/sugary foods, sugar-sweetened beverages, and alcohol, represented 24–26% and 21–23% kcal/day, for males and females, respectively. Canadians are eating more foods categorized as Tier 1–3, rather than Tier 4. Adults with the highest intakes of Tier 4 and “other foods” had lower intakes of macronutrients and increased body mass index. These findings can be used by policy makers to assist in identifying targets for food reformulation at the nutrient level and quantitative guidance to support healthy food choices.

Full textAbstract:
Background: Malnutrition among Filipino children persists; underscoring the value of nutritional assessment procedures. In the Philippines, this is carried out at the local level in its annual Operation Timbang [weigh] (OPT or OPT Plus). Local government unit officials observed higher malnutrition prevalence rates in nutrition survey reports of the Department of Science and Technology’s Food and Nutrition Research Institute (DOST-FNRI) compared with its OPT. A revisit of the OPT provided evidence on the comparability of the two data sets and sources of variance analyzed.
Objectives: 1) describe municipal level assessment of OPT in 10 barangays of Abra de Ilog municipality; 2) identify facilitating and hindering factors in OPT; and 3) compare OPT results with DOST-FNRI local nutrition survey in Abra de Ilog and identify potential sources of variance therefrom.
Methods: Primary data were collected using focus group discussions and key informant interviews. Height and weight data were collected using standard methods of anthropometry.
Results: The OPT/OPT Plus is the mass weighing of 0-71 months old children, including height measurements conducted during the first and fourth quarter of the year in Abra de Ilog. It was found that facilitating factors were availability of calibrated equipment, latest master list, local government support and budget. Lack of manpower, work overload, low honoraria, low work commitment, uncooperative mothers and high turnover of barangay [village] nutrition scholars hindered OPT implementation. The Abra de Ilog 2016 OPT Plus and the 4th quarter “OPT” reported lower malnutrition prevalence rates than the DOST-FNRI local survey.
Conclusions: Significant differences in the two data sets could misguide program implementation. As an outcome of Sustainable Development Goal No. 2 of Zero Hunger, potential misclassification of nutritional status and misreporting of malnutrition prevalence rates have implications for the mapping of malnutrition, hence delivery of targeted nutrition intervention packages.

AbstractObjective:To investigate the feasibility of using commercially available data on household food consumption to carry out food and nutritional surveillance.Design:Taylor Nelson Sofres (TNS) collects information on foods brought home for consumption among a representative quota sample of the British population. In total, 33 177 households and 105 667 individuals provided data between 1991 and 2000. These were used to investigate sociodemographic, geographical and temporal trends in purchase patterns of the main macronutrients and four groups of marker products.Results:Sociodemographic characteristics of the TNS sample were broadly consistent with those of the British population. Estimated energy intakes were slightly low (1667±715 kcal) in comparison with other national data. However, percentage energy contributions were consistent with national trends: e.g. consumption of alcohol in the home increased between 1991 and 2000 with higher intakes among more affluent households, while fat intakes decreased slightly over the same period. Significant temporal, geographic and socio-economic trends were found for all nutrients (P < 0.0001). Intakes of marker products were sparse (purchased by <4% of households), but significant variations were detected in the proportion of households purchasing some or all of the marker products across temporal, geographic and socio–economic strata.Conclusions:A prospective nutrient surveillance system could be used to trace consumption patterns of foods or nutrients to inform nutritional surveillance. However, existing data sources would require a number of modifications to increase their suitability for such a project. Increasing surveillance to consider ingredients would require the development of a central coding system, with electronically linked barcode, ingredient and nutrient information.

Background: Lack of evidence on the burden and risk factors for malnutrition among children with cerebral palsy (CP) in Vietnam limits evidence-based interventions. We aimed to define the nutritional status of children with CP in Vietnam. Materials and Methods: The study utilized data from active prospective hospital-based surveillance modelled on the Pediatric Active Enhanced Disease Surveillance system. Children (0–18 years) with CP attending the National Children’s Hospital Hanoi, Vietnam between June–November 2017 were included. Data on demographic, clinical and rehabilitation status were collected following detailed neurodevelopmental assessment. Anthropometric measurements were taken. Nutritional status was determined using the World Health Organization guideline. Results: Of 765 children (the mean (SD) age was 2.6 (2.5) years; 35.8% were female), 28.9% (n = 213) were underweight and 29.0% (n = 214) stunted. The odds of underweight were significantly higher among children aged >5 years and/or having a monthly family income of <50 USD. Underweight and/or stunting was high among children with quadriplegia (81%, n = 60 and 84.5%, n = 87) and/or Gross Motor Functional Classification System (GMFCS) level IV–V (62.5%, n = 45 and 67.0%, n = 67). Nearly one-third of intellectually impaired and more than half of hearing-impaired children were underweight and/or stunted. Conclusions: Poor economic status and increased motor severity increased vulnerability to malnutrition. Our findings will inform nutritional rehabilitation programs among these vulnerable children.

Full textAbstract:
This essay aims to debate the minimum clock hours of instruction necessary for obtaining a bachelor's degree in nutrition considering the challenges to educate health professionals. Official documents on the minimum clock hours of instruction required by undergraduate nutrition programs were analyzed to investigate compliance with the curriculum guidelines for the area, the law that regulates the profession of dietitian, and the necessary education for the Sistema Único de Saúde (Unified Health Care System). Compared with other health programs, nutrition presented the smallest increase in the minimum clock hours of instruction required for the degree. The changes that occurred in the epidemiological, demographic, and nutritional profile of the population and scientific advances require specific nutrition actions. Since Sistema Único de Saúde focuses on comprehensiveness in the three levels of care, on humanization, and on health care, the theoretical and methodological concepts given in undergraduate programs need to be improved for the dietitians education to meet the Sistema Único de Saúde needs. Incorporation of the knowledge needed for working with food and nutritional phenomena, including its social and cultural dimensions, management of public policies, quantity cooking, and food and nutritional surveillance requires a higher minimum clock hours of instruction. In conclusion, dietitians need a minimum clock hours of instruction of 4,000 to acquire a proper education, integrate into the university life, and coordinate interdisciplinary experiences of the triad teaching/research/extension.

Introdução: A Vigilância Alimentar e Nutricional (VAN) foi proposta mundialmente em meados da década de 60 e foi consolidada na década de 70 através de três importantes eventos internacionais: a Conferência Mundial de Alimentos (1974), a Conferência de Alma-Ata (1978), e a proposta de uma Revolução pela Sobrevivência e Desenvolvimento da criança (1983). No Brasil, desde os anos 90, o Ministério da Saúde (MS) tem incentivado o monitoramento alimentar e nutricional da população atendida pela Atenção Primária à Saúde (APS), vinculado às rotinas dos serviços, através do Sistema de Vigilância Alimentar e Nutricional (SISVAN). Desde então, diversos projetos de implantação do SISVAN vem sendo desenvolvidos nos municípios brasileiros. No entanto, há poucos estudos avaliando as informações registradas no SISVAN, bem como sua cobertura no país. Objetivos: 1) Avaliar para 2006 a cobertura do Sistema de Vigilância Alimentar e Nutricional (SISVAN- Ministério da Saúde - MS) nas Coordenadorias Regionais de Saúde do Rio Grande do Sul (CRSs) e no Estado; 2) Avaliar a concordância entre as classificações nutricionais registradas pelos profissionais no sistema com aquelas geradas por este estudo e; 3) Caracterizar o estado nutricional de crianças de 0-10 anos acompanhadas pelo SISVAN no RS no referido ano. Métodos: Estudo transversal descritivo de base secundária em que se analisaram dados de 63.320 crianças de 0-10 anos acompanhadas pelo SISVAN em 2006 no RS. A cobertura do sistema foi avaliada pela comparação do total de crianças acompanhadas pelo sistema em 2006 com a estimativa da população de menores de 10 anos coberta pela Estratégia de Saúde da Família nos municípios gaúchos no mesmo ano (DATASUS, 2010). A classificação do estado nutricional informado pelo profissional em 2006 no sistema [que foi baseada no índice peso/idade, em percentis, com referência na curva de crescimento do NCHS (OMS, 1983)], foi recalculada neste estudo a partir das medidas de peso, idade e sexo constantes no banco de dados, a fim de avaliar concordância entre classificações. O estado nutricional foi avaliado segundo a referência da Organização Mundial da Saúde (WHO, 2006). Foram considerados déficits nutricionais quando os índices peso/idade (P/I), massa corporal para idade (IMC/I) e estatura para idade (E/I) tinham valores de escore z inferiores a -2, e excesso de peso valores de IMC/I com escore z maior ou igual a +2. Foram calculadas freqüências relativas e absolutas, médias e desvios-padrão das variáveis, utilizando-se os testes t de Student para amostras independentes, qui-quadrado de Pearson e o coeficiente Kappa ponderado para comparação de médias, proporções e concordância de classificações, respectivamente. Resultados: A cobertura do sistema no RS foi de 10,54% (oscilando de 2,2% a 21,0% entre CRSs). O valor do coeficiente kappa ponderado entre classificações nutricionais foi de 0,426 para o RS (oscilando de 0,135 a 0,661 entre CRSs). As freqüências dos desvios nutricionais foram: déficit E/I: 9,1% (menores de 5 anos) e 5,8% (5-10 anos); déficit P/I: 3,7% (menores de 5 anos) e 4,0% (5-10 anos); déficit IMC/I: 3,1% (menores de 5 anos) e 2,8% (5-10 anos); e excesso de peso: 9,4% (menores de 5 anos) e 7,9% (5-10 anos). Conclusões: Aponta-se o excesso de peso e o déficit estatural entre as crianças acompanhadas pelo SISVAN, mas requere-se cautela à extrapolação dos resultados, devido às baixas cobertura do sistema e concordância das classificações nutricionais registradas.Introduction: The Nutritional and Food Surveillance System was proposed internationally in the mid 60‟s and was consolidated in the 1970‟s through three important international events: The World Food Conference (1974), the Alma-Ata Conference (1978) and the proposition for a Child Survival and Development Revolution (1983). In Brazil, since the 1990‟s, the Ministry of Health has encouraged the nutritional and food monitoring of the population treated by the Primary Healthcare Service, associated to service routines, through the Nutritional and Food Surveillance System (SISVAN). Since then several projects for implementing SISVAN have been developed in Brazilians cities. However, there are few studies assessing the information recorded in SISVAN, as well as its coverage across the country. Objectives: 1) To assess, in 2006, the coverage of Nutritional and Food Surveillance System (SISVAN-MH) in the Regional Health Coordination Offices (CRSs) of the Rio Grande do Sul (RS) and in the whole State; 2) To assess the agreement between nutritional classifications recorded by the professionals in the system and those provided by these study; 3) To characterize the nutritional status of children from age 0 to 10 followed by SISVAN in RS in these year. Methods: Descriptive cross-sectional study of secondary database analyzing data from 63,320 children aged 0-10 followed by SISVAN in 2006, in RS. The system coverage was assessed by comparing the total number of children followed by the system in 2006 with the estimate for the population of children below age 10 covered by the Strategy of Health´s Family in the RS cities at the same year (DATASUS, 2010). The nutritional status, stated by professionals in 2006 in the system [based on the weight/age index, in percentiles according to the reference from the NCHS(OMS, 1983)] was recalculated in this study using weight measurements, age and sex data from the database in order to evaluate the agreement between classifications. The nutritional status was evaluated according to the reference from the World Health Organization (WHO, 2006). The score z values smaller than -2 for the indexes weight-for-age (W/A), BMI-for-age(BMI/A) and height-for-age (H/A) were considered nutritional deficits. The score z values greater then +2 for the index BMI/A were considered overweight. Relative and absolute frequencies, means and standard deviations of variables were calculated, using Student‟s t test for independent samples, Pearson‟s chi square test and weighted kappa coefficient to compare means, ratios and classification agreement, respectively. Results: The system coverage in RS was 10.54% (ranging from 2,2% to 21,0% across CRSs). The value of the weighted kappa coefficient between nutritional classifications was 0.426 in RS (ranging from 0.135 to 0.661 across CRSs). The frequencies of nutritional deviations were: H/A deficit: 9.1% (children below age 5) and 5.8% (children aged 5 to 10 years old); W/A deficit: 3.7% (children below age 5) and 4.0% (children aged 5 to 10 years old); BMI/A deficit: 3.1% (children below age 5) and 2.8% (children aged 5 to 10 years old); and overweight: 9.4% (children below age 5) and 7.9% (children aged 5 to 10 years old); Conclusions: The results showed the overweight and the height deficit among children followed by SISVAN, but they should be interpreted with caution because of low coverage of SISVAN in RS and the poor quality of anthropometric data registered.

La immunoteràpia nutricional es basa en fomentar la salut mitjançant el consum de compostos bioactius presents de manera natural en els aliments, com les procianidines, un tipus de flavonoid, i/o l’àcid docosahexaenoic (DHA), un àcid gras omega-3, optimitzant la funcionalitat del propi sistema immune i millorant així el seu paper com a responsable de la preservació de l’organisme enfront desestabilitzadors de la homeòstasis. La recerca que aquesta tesi abasta es centra en el paper del perfil nutricional en la regulació de la interacció immunitat-metabolisme (immunometabolisme).
Amb aquesta finalitat, en la primera part del treball presentat en aquesta tesi, es va determinar si els macròfags, les cèl•lules efectores de la immunitat innata, poden percebre de manera diferencial la composició de la dieta. Hem demostrat que els compostos bioactius dels aliments modulen, a nivell molecular, l’activació dels macròfags. A més, aquest efecte immunomodulador és dependent del compost, on factors intrínsecs com les propietats químiques o nutritives són determinants per la seva bioactivitat.
La segona part va tenir com a objectiu determinar el paper primordial del patró nutricional en la regulació de la interacció entre el sistema immune i el metabolisme. Utilitzant un model d’obesitat induïda per la dieta es va inferir que, mentre una dieta hipercalòrica provoca un deteriorament de l’immunometabolisme, el consum de bioactius pot enfortir-ne la relació.
A la tercera part, es va analitzar el paper de les interaccions gen-dieta en l’expressió fenotípica dels trets associats amb la obesitat. Per aquest motiu, dos races de rates congènites, fenotípicament diferents, van ser sotmeses a un desequilibri immunometabòlic com a conseqüència de la ingesta d’una dieta hipercalòrica. Es va deduir que les interaccions entre els factors genètics i nutricionals són fonamentals per a la susceptibilitat d’un genotip a l’obesitat induïda per la dieta.
Hem establert que el perfil nutricional és una eina poderosa per orientar la funcionalitat de l’eix immunometabòlic. A més, arribem a la conclusió que compostos bioactius presents en els aliments poden millorar-ne l’eficiència d’aquest eix, promovent així un estat saludable.La immunoterapia nutricional se basa en fomentar la salud mediante el consumo de componentes bioactivos presentes de forma natural en los alimentos, como las procianidinas, un tipo de flavonoides, o el ácido docosahexaenoico (DHA), un ácido graso omega-3, optimizando la funcionalidad del propio sistema inmune y mejorando así su papel como responsable de la preservación del organismo frente a desestabilizadores de la homeostasis. La investigación que engloba esta tesis se centra en el papel del perfil nutricional en la regulación de la interacción inmunidad-metabolismo (immunometabolismo). Con esta finalidad, en la primera parte del trabajo presentado es esta tesis, se determinó si los macrófagos, las células efectoras de la inmunidad innata, pueden percibir de manera diferencial la composición de la dieta.

En la tercera parte, se analizó el papel de las interacciones gen-dieta en la expresión fenotípica de los rasgos asociados con la obesidad. Para ello, dos razas de ratas congénitas, fenotípicamente diferentes, fueron sometidas a un desequilibrio immunometabólico como consecuencia de la ingesta de una dieta hipercalórica. Se dedujo que las interacciones entre los factores genéticos y nutricionales son fundamentales para la susceptibilidad de un genotipo a la obesidad inducida por la dieta. Hemos establecido que el perfil nutricional es una herramienta poderosa para orientar la funcionalidad del eje immunometabólico. Además, llegamos a la conclusión que compuestos bioactivos presentes en los alimentos pueden mejorar la eficiencia de este eje, promoviendo así un estado saludable.
Nutritional immunotherapy is based on promoting health through the dietary intake of natural bioactive compounds found in food, such as the procyanidins and docosahexaenoic n-3 polyunsaturated fatty acid (DHA), optimising the functionality of the host’s own immune system and improving its role in the preservation of the body against destabilisers of homeostasis. The research that this thesis encompasses is focused on the role of the nutritional profile in the regulation of immunometabolism. To accomplish this purpose, in the first part of the work presented in this thesis, we determined whether macrophages, the effector cells of innate immunity, could differentially sense dietary composition. We demonstrated that bioactive food compounds modulate, at the molecular level, the functionality of macrophages by hindering macrophage activation. Furthermore, this immunomodulatory effect is compound-dependent, relying on the intrinsic factors of each compound, such as chemical and nutritional properties, to determine its bioactivity. The second part was aimed at determining the role of the dietary pattern within the complex crosstalk of immunity and metabolism using an in vivo model of diet-induced obesity. We determined that immunometabolic regulation depends on the nutritional profile. While a diet based on foods with a high energy content can weaken immunometabolism, the presence of bioactive foods can strengthen the relationship. Within the third part, we evaluated the role of gene-diet interactions in the phenotypic expression of obesity-related complex traits. Using a diet-induced obesity model, two distinct genetic backgrounds (phenotypically different inbred rat strains) were immunometabolically challenged. Our results revealed that interactions between genetic and dietary factors are fundamental for the susceptibility of a genotype to diet-induced obesity. We established that the nutritional profile is a powerful tool to target the functionality of the immunometabolic axis. We further concluded that bioactive compounds present in food improve the efficiency of this axis, thereby promoting a healthy state.

Full textAbstract:
The use of fatty acid (FA) analysis has become an important tool in recent years to investigate a broad spectrum of questions in fisheries and aquatic ecology. One of these applications has been the use of FA profiles as biomarkers for indicating diet and recent feeding history of fishes and other aquatic consumers. Differences in forage FA profiles and spatial differences in food web structure within aquatic systems may lead to corresponding spatial patterns of FA profiles in consumers, thereby facilitating the potential applicability of FA biomarkers as indicators of habitat use and origin for mobile consumers such as fishes. However, little information is available regarding differences in FA profiles among habitat types in river-floodplain ecosystems and the time-scale over which fish FA profiles change when fish move between habitats that differ in the FA profiles of prey resources. The objectives of this study were to test whether the tissue FA profiles of channel catfish (Ictalurus punctatus) differed among three reaches of the lower Kaskaskia River and its floodplain lakes, to determine the time-course of tissue FA profile turnover when fish are relocated to a new habitat type, and to compare FA profiles among muscle, liver, and adipose fin tissues in channel catfish. Fatty acid profiles of channel catfish were significantly different among sites, especially between upper and lower river sites, and between river channel and oxbow lake sites, suggesting differing energy sources among habitats and river reaches in the Kaskaskia system. More specifically, there was a significant increase in the essential FAs, 18:2n-6 and 18:3n-3, in channel catfish with increasing distance downstream, which could reflect an increase in river-floodplain connectivity at downstream sites. Channel catfish transplanted from the Kaskaskia River to ponds at Southern Illinois University Carbondale showed a significant linear decrease in n-3 and medium-chain polyunsaturated FAs (MC-PUFA), and a significant linear increase in monounsaturates (MUFA) with longer residence time in a lentic environment. Liver tissue exhibited the fastest turnover rate of the three tissue types (< 2 weeks), with muscle and adipose fin tissue both displaying similar, longer turnover times (approximately 10 weeks). Results of this study support the use of FA profiles as indicators of energy sources for fishes in large river-floodplain ecosystems, including the potential for indentifying habitat-specific (river channel vs. floodplain lake) or river reach-specific energy sources. Additionally, results of this study provide a timeline for FA turnover in channel catfish tissues when fish move among habitats with distinct FA signatures, which is crucial for detecting temporal shifts in use of habitat-specific energy sources by channel catfish. Results also suggest that adipose fin tissue samples may be a less invasive alternative to muscle tissue for analysis of FA profiles in channel catfish. Improved understanding of which habitats or river reaches provide trophic support for riverine fishes through use of FA profile analysis has potentially important implications for habitat conservation and rehabilitation in river-floodplain ecosystem.

Full textAbstract:
Epidemic obesity in the U.S. has prompted exploration of causal factors related to the built environment. Recent research has noted statistical associations between the spatial accessibility of retail food sources, such as supermarkets, convenience stores, and restaurants, and individual characteristics such as weight, socioeconomic status, and race/ethnicity. These studies typically use residential proximity or neighborhood density to food sources as the measure of accessibility. Assessing food environments in this manner, however, is very limiting. Since most people travel outside of their neighborhood on a daily basis, the retail food sources available to individuals residing in the same area could vary widely.
This research developed new techniques for describing food accessibility or food environments based upon individuals’ activity and travel patterns, or their activity spaces. Researchers have previously used travel diaries to study activity and travel behavior, but these are burdensome for participants, and are prone to recall error and other inaccuracies. This study explored use of global positioning system (GPS) to identify participants' activity spaces, and employed a geographic information system (GIS) to assess the retail food sources located within these spaces. This produced ‘activity-based’ measures of individual retail food accessibility that do not rely on areal units, nor require travel diaries.
Participants included 121 residents of a census tract in Lexington, Kentucky who agreed to carry GPS trackers for three workdays, and complete surveys regarding weight, socioeconomic and demographic characteristics, and diet and food purchasing habits. The types and relative frequencies of food locations within their activity spaces were compared to those within close proximity to the census tract. Dietary and food purchasing habits were subsequently analyzed in relation to activity-based food environment measures.
The results of this study demonstrate substantial potential for misclassification bias in food accessibility research based on residential proximity or neighborhood density. Furthermore, this study observed statistically significant relationships between the new activity-based food accessibility measures and some personal characteristics and food-related behaviors. Despite some limitations, the techniques developed in this research show great potential for future research, which should be explored further in a variety of contexts.

Este trabalho tem como objetivo avaliar a compreensão da representação gráfica das informações nutricionais presentes nos rótulos de alimentos por adolescentes escolares. Foi realizado um estudo transversal com 56 adolescentes escolares (n=56), com idades compreendidas entre 15 e 17 anos, matriculados em uma escola particular de Porto Alegre/RS. Para a realização da pesquisa foi utilizado um questionário específico estruturado com nove perguntas fechadas dicotômicas e de múltipla escolha. Os resultados mostram que 41% dos adolescentes escolares costumam ler os rótulos antes da compra, 71% afirmam conhecer o significado de valor energético dos alimentos, 63% declaram compreender as informações escritas nos rótulos e 61% confiam nas informações escritas nas embalagens de alimentos. A maioria dos adolescentes compreende os componentes nutricionais presentes nos rótulos de alimentos brasileiros, e apenas 45% entendeu as informações nutricionais presentes no modelo de rótulo Traffic Light Labelling ou “Semáforo Nutricional”, evidenciando que a rotulagem utilizada no Brasil apresentou resultados mais positivos de compreensão. Os resultados do estudo indicam que um número relevante de adolescentes (63%) compreende os componentes nutricionais presentes nos rótulos de alimentos brasileiros e um número significativo de indivíduos compreendeu e identificou a informação nutricional mais saudável descritas nos rótulos; no entanto, sugere-se o desenvolvimento de programas de educação nutricional para potencializar a compreensão das informações nutricionais contidas nos rótulos para este perfil de consumidor.
This paper aims at evaluating the understanding of graphical representation of nutritional information on food labels by young adolescent students. Therefore, it was carried out a cross-sectional study with 56 young adolescent students (n = 56), aged between 15 and 17 years, enrolled in a private school in Porto Alegre / RS. A specific questionnaire containing nine dichotomous and multiple choice closed questions was used for data gathering. The results showed that 41% of young adolescent students usually read the labels before purchasing, 71% of them claim to know the meaning of the energetic value of food, 63% say they understand the information written on the labels, and 61 % trust the information written on food packages. Most adolescents understand the nutritional components present on the labels of Brazilian foods, and only 45% understood the nutrition information on the Traffic Light labelling system, showing that the labels used in Brazil are better understood. The results indicate that a meaningful number of adolescents (63%) understands the nutritional components on the labels of Brazilian food, and a meaningful number of individuals understood and identified the healthiest nutritional information given on labels; however, it is suggested the development of nutrition education programs to enhance the understanding of the nutritional information on the labels for this consumer profile.

Introdução: A Vigilância Alimentar e Nutricional (VAN) é um conjunto de estratégias de Vigilância em Saúde, incluindo o Sistema Nacional de Vigilância Alimentar e Nutricional (SISVAN), para monitorar e analisar continuamente as condições alimentares e nutricionais da população usuária do Sistema Único de Saúde (SUS), com o objetivo de subsidiar ações, programas e políticas. Objetivos: Descrever a produção científica brasileira recente sobre VAN e analisar em que medida a concepção presente nos trabalhos se aproxima do conceito estabelecido na Política Nacional de Alimentação e Nutrição (2012); e descrever as coberturas da avaliação do estado nutricional e do consumo alimentar da população usuária de serviços públicos de saúde registrada no SISVAN Web, entre 2008 e 2013. Métodos: O presente estudo está organizado em dois eixos metodológicos: uma revisão bibliográfica sobre o conceito de VAN presente na produção científica brasileira recente e dois estudos originais ecológicos com descrição das coberturas da avaliação do estado nutricional e do consumo alimentar a partir dos dados do SISVAN Web. Resultados: Na revisão bibliográfica, foram identificados artigos majoritariamente voltados para a análise de inquéritos populacionais, com menor contribuição sobre sistemas de informação em saúde e avaliação de serviços de saúde. Nos estudos originais, a cobertura total média do estado nutricional no Brasil variou de 9,78 por cento a 14,92 por cento ; e a do consumo alimentar variou de 0,13 por cento a 0,41 por cento . Ambas apresentaram tendência estatisticamente significativa de aumento e diferenças entre as unidades da federação e macrorregiões. Verificou-se a priorização da VAN voltada para o público materno-infantil, a proveniência dos dados de estado nutricional relacionada ao público prioritário do Programa Bolsa Família, e de consumo alimentar relacionada à presença de nutricionistas na Atenção Básica. Conclusão: Apresenta-se um panorama da produção científica recente sobre VAN e do acompanhamento do estado nutricional e do consumo alimentar nos serviços de saúde brasileiros, desvelando contextos em que recursos precisam ser mobilizados para melhoria da VAN.Introduction: The Food and Nutrition Surveillance (FNS) is a set of surveillance strategies within the Health Surveillance, which includes the National Food and Nutrition Surveillance System (Sistema Nacional de Vigilância Alimentar e Nutricional - SISVAN), that aims at continuously monitoring and analyzing the food and nutritional status of the population attended by the Brazilian National Health System (Sistema Único de Saúde - SUS) and supporting actions, programs and policies. Objectives: to describe the Brazilian scientific literature on FNS and analyze to what extent the studies approach is linked/associated to the concept of the National Food and Nutrition Policy (2012); to analyze the coverage of the assessment of the nutritional status and the food intake of the users of the public health services registered on the Web SISVAN between 2008 and 2013. Methods: This study is organized in two methodological axes: a literature review on the concept of FNS present in recent Brazilian scientific production and two original ecological studies describing the assessment of the coverage of the nutritional status and food intake from the Web SISVAN data. Results: In the literature review, we found that the papers were mainly focused on the analysis of population surveys with smaller contribution of studies on health information systems and evaluation of health services. In the original studies, the average full coverage in Brazil ranged from 9.78 per cent to 14.92 per cent for the nutritional status and from 0.13 per cent to 0.41 per cent for the food intake. Both showed statistically significant trends of increase and differences between the Brazilian Federal Units and macro-regions. The FNS was prioritized for mother-child pairs, priority public of the Bolsa Familia Program, in the case of nutrition status data, and related to the presence of nutritionists in the primary healthcare services, in the case of food intake data. Conclusion: We presented an overview of recent scientific literature on FNS and of the monitoring of nutritional status and food intake in the Brazilian health services, revealing contexts where resources need to be mobilized to improve the FNS.

Full textAbstract:
L’objectif principal de cette thèse est la caractérisation et l’analyse des transformations du système alimentaire des Inuit du Nunavik, et en particulier les enjeux soulevés à l’intersection des interactions humains-milieux, puis les conséquences encourues pour le bien-être et la santé des Inuit. Des pistes de solution pour améliorer la résilience du système alimentaire dans cette région nordique y sont explorées, dont la principale est le développement de projets de jardinage communautaire. La collecte des données pour réaliser les quatre articles qui forment le corps de cette thèse s’est échelonnée entre octobre 2015 et mars 2019 dans les villages nordiques de Kuujjuaq et Kangiqsujuaq, au Nunavik. Différentes méthodes ont été combinées, dont la principale se base sur les principes de la recherche-action participative. Les résultats illustrent que les aliments traditionnels issus des activités de chasse, de pêche et de cueillette demeurent des vecteurs importants de la relation au territoire et du bien-être inuit, malgré le fait qu’ils ne représentent plus qu’une fraction de la diète. La perte de mobilité et l’adoption d’un nouveau mode de vie, accompagnées et rendues possibles par la transition nutritionnelle, ont perturbé les interactions humains-milieux à différents niveaux. La plus grande pression exercée sur l'environnement naturel provient des activités humaines menées ailleurs sur la planète et d’un modèle de consommation incompatible qui génèrent de nombreuses externalités négatives sur l’environnement et la santé humaine. À travers leur alimentation, les Inuit du Nunavik sont dorénavant connectés au reste du monde par le biais du système alimentaire globalisé, dont les ramifications complexes couvrent toute la planète Or, au Nunavik, les défauts inhérents à la chaîne de production agroalimentaire globalisée s’expriment d’une façon bien singulière. L’intensification des liens entre économie inuit et économie globalisée concourt à placer les territoires nordiques dans une position d’échange inégal et de dépendance envers les producteurs et les fournisseurs d’un secteur agroalimentaire exogène au sein duquel les résidents du Nord ont peu d’occasions de se faire entendre. La souveraineté alimentaire à l’égard des aliments du marché est ainsi fortement limitéeThe main objective of this thesis is the characterization and analysis of the transformations of the Nunavik Inuit food system, and particularly the issues raised at the intersection of human-environment interactions and their consequences for Inuit health and well-being. Possible solutions to improve the resilience of the food system in this northern region are explored, the main one being the development of community gardening projects. The collection of data to complete the four articles that make up the body of this thesis took place between October 2015 and March 2019 in the northern villages of Kuujjuaq and Kangiqsujuaq, Nunavik. This research combines different methods, the main one being based on the principles of participatory action research. The results illustrate that traditional foods from hunting, fishing and gathering activities continue to be important drivers of Inuit’s well-being and relationship to the land, despite the fact that they are now consumed in smaller quantities. The loss of mobility and the adoption of a new way of life, accompanied and made possible by the nutritional transition, have disrupted human-environment interactions at different levels. The greatest pressure on the natural environment comes from human activities elsewhere in the world and from a pattern of inconsistent consumption that generates many negative externalities on the environment and human health. Through the food they eat, the Inuit are now connected to the rest of the world through the globalized food system, the complex ramifications of which cover the entire planet. In Nunavik, the defects inherent in the global agri-food production chain are expressed in a very singular way. The intensification of the links between the Inuit economy and the globalized economy contributes to placing the northern territories in a position of unequal exchange and dependence on the producers and suppliers of an exogenous agri-food sector in which northern residents have few opportunities to be heard. Food sovereignty over market foods is thus severely limited

Full textAbstract:
AbstractFish and feed waste provide most of the nutrients required by the plants in aquaponics if the optimum ratio between daily fish feed inputs and the plant growing area is sustained. Thus, the fish feed needs to fulfil both the fish’s and plant’s nutritional requirements in an aquaponic system. A controlled fish waste production strategy where the nitrogen, phosphorus and mineral contents of fish diets are manipulated and used provides a way of influencing the rates of accumulation of nutrients, thereby reducing the need for the additional supplementation of nutrients. To optimize the performance and cost-effectiveness of aquaponic production, fish diets and feeding schedules should be designed carefully to provide nutrients at the right level and time to complement fish, bacteria and plants. To achieve this, a species-specific tailor-made aquaponic feed may be optimized to suit the aquaponic system as a whole. The optimal point would be determined based on overall system performance parameters, including economic and environmental sustainability measures. This chapter thus focuses on fish diets and feed and reviews the state of the art in fish diets, ingredients and additives, as well as the nutritional/sustainable challenges that need to be considered when producing specific aquaponic feeds.

Full textAbstract:
AbstractCassava and sweetpotato are major factors in food security across sub-Saharan Africa. Though cassava and sweetpotato varieties that are early maturing and resistant to diseases have been developed, many farmers still grow local varieties. Cassava and sweetpotato cultivars that mature between 6 and 12 and 3 and 4 months after planting, respectively, are available. The objective of the synthesis was to obtain a general overview of cassava and sweetpotato production in Matiliku subcounty of Makueni County in semi-arid eastern Kenya before the establishment of a seed system for them. Participatory rural appraisal and focused group discussions with key stakeholders in Makueni County on the current status of these crops provided very useful information. It was observed that there are a few early cassava and sweetpotato adopters, meaning a lot of effort in communicating the need to commercialize them needs to be made. Even though the farmers had sufficient experience in growing them at subsistence level, they were searching for cultivars that combine both nutritional and food security. There is a need to engage more extension service providers in order to campaign on their adoption. There is a need to carryout training and awareness creation on their role in food security and wealth creation.

Adolescents' obesity is a major concern in our modern life that could lead to significant increase in the rate of obese future generations and consequently in the health budget. The ASSO (Adolescence Surveillance System for Obesity prevention) project in Italy is tackling this new pandemic using the new e-technology through a multi facets monitoring system on life style including food consumptions, meal patterns and habits, alcohol, smoking, physical activity, fitness and sedentariness, and biological/genetic, and socio-cultural/environmental characteristics of adolescents. The project has been recently piloted in the South of the country. This chapter summarizes the design and structure of the ASSO system, its implementation and the results of an evaluation process for its possible extension to the whole Italian territory and to other European realities as a national surveillance system.

Intermittent microwave convective drying (IMCD) is an advanced drying system where a unique volumetric heating mode is facilitated. However, the physical phenomena of IMCD system and its effect on nutritional quality are not well understood yet. The aim of this research is to develop a coupled IMCD and quality prediction model and experimentaslly validate it. A coupled 3D mathematical model considering Maxwell’s equation for electromagnetic heating, and reaction kinetics for predicting quality was developed and validated. COMSOL Multiphysics, engineering software was used to solve the developed model. It is found that IMCD significantly affect the nutritional quality during drying of apple tissue.

Full textAbstract:
The pressure required for treatment of food ranges from 300 to 600 MPa, depending on the food being processed and the desired results, higher pressure giving better and more economical results. However, there are currently no predictable, reliable, and repeatable safety devices available for very high pressures like 600 MPa. Rupture disks have a short life at these pressures, and pressure relief valves for very high pressure are not repeatable. Thus the possibility of using a system design is an attractive alternative that will make the overpressure protection more reliable and controllable. In current applications, high-pressure vessels normally operate from a few MPa to 200 MPa, for example when extracting substances, compacting powder materials, or healing defects in materials. The pressure medium is typically a pure gas or a liquid. Here existing devises serve their purpose. The request for mild treatment of food to enhance safety and quality has created a niche for very high pressure. With this new technique the food is treated at low temperature and high pressure for a short time. The treatment inactivates micro organisms but maintains the nutritional and organoleptic values of the food, achieving a food with high quality and increased safety throughout its commercial shelf life.

Dry seeds of peas (Pisum sativum L.) have long been used as a staple food and feed globally, and its nutritional, health and ecological benefits comply with growing demand for novel vegan foods intended for health and sustainability conscious individuals. The aim of this study was to review research findings and latest information on field pea usage as a functional ingredient in vegan foods. Monographic method was used to analyse field pea Pisum sativum L. usage as a diverse and multifunctional ingredient in vegan foods, covering latest available information on chemical composition of field pea and main food ingredients made from field pea, focusing on the varieties from which yellow split pea is produced; their impact on ready product’s nutrition, sensory properties and application in food industry. Major types of novel vegan foods containing field peas available on market were named. Pea protein, starch and fibre have demonstrated functional properties in different food systems, including – emulsification, oil-in-water system stabilisation, texture modification, binding, gelation, foaming, and solubility. It is functionally possible and nutritionally and ecologically desirable to develop novel vegan foods intended as animal product alternatives with acceptable sensory properties.

Full textAbstract:
Assuring that food products have acceptable quality and are safe to consume requires maintaining adequate nutrition levels and fulfilling consumer expectations. Quality losses can lead to food waste, resulting in increased economic costs and low consumer confidence. Therefore, quality expectations should be maintained at an acceptable level for consumer purchase and consumption. It is well known that a cold environment reduces the respiratory activities and kinematics of nutritional degradation. The cooling temperature is critical since lower than recommended cold temperatures may cause chill damage. Therefore, the food industry intensively employs cold storage methods to slow respiration rates, inhibit harmful bacterial growth, reduce water loss, and prolong shelf life in order to maintain product nutritional value and quality. Improving product cooling efficiency will reduce energy costs that are a significant expense for fruit and vegetable processors. Understanding the cooling process is key to the development of new technology and processes. However, most natural food products are not conformed to simple geometric shapes or uniform properties and distributions. Thus, the cooling process of an agricultural product (cucumbers) was investigated in this study. The study was conducted in a packing house, where the cooling temperature of the cucumbers was recorded by placing multiple thermocouples in the produce after boxing and palletizing as well as cold storage. The test results showed that individual produce cooling was relatively easy to predict. However, boxed and palletized cucumber cooling showed significant variations. For example, the temperature of the cucumbers changed depending on their location in the box in addition to the box location on the stack. In the case of boxed produce cooled by natural convection cooling, the temperature changed from 25 to 18 °C after three hours. However, in the case of palletized tunnel cooled, the temperature change ranged from 25 to 11 °C and 25 to 18 °C after nearly three hours of cooling. Indeed, the temperature differences indicated that the cooling rate has significant variations depending on the location of the produce. Some parts of the pallet received more direct contact with the forced cold air than other parts. Thus, it is very important for produce processors to understand cooling system performance. The study emphasized that efficient use of energy is one of the areas that can have not only significant cost savings but can also improve produce shelf life, reduce food waste, and maintain consumer confidence.

Full textAbstract:
The United States is the second largest citrus producer in the world. Florida and California are the two major producing states. While oranges from California are mainly used for fresh fruit consumption, more than 90% of oranges produced in Florida are processed to juice (FAO 2008). Consumers demand high quality and convenient products with natural flavor and taste, and appreciate the “fresh” perception of minimally processed juices. They also look for safe, natural, and healthy products without additives and preservatives. New processing technologies promise to meet all these demands without compromising food safety. Commercial orange juice is thermally processed to inactivate pectinesterase (PE) and spoilage organisms. Active PE causes clarification of orange juice by cloud loss, which is considered a quality defect (Boff et al. 2003). Thermal processing can be detrimental to the organoleptic and nutritional qualities of the juice (Sloan 1995), so the development of non-thermal technologies (Barbosa-Canovas et al. 1998) is desirable in the citrus juice industry. Dense phase carbon dioxide (DPCD) is a non-thermal technology that can inactivate certain micro-organisms and enzymes at temperatures low enough to avoid the thermal effects of traditional pasteurization. This technology relies on the chemical effect of CO2 on micro-organisms and enzymes. DPCD pasteurization technology is commercially available. Most of the commercialization efforts so far have been from Praxair Inc. (Burr Ridge, IL). Based on technology licensed from the University of Florida (Balaban et al. 1988, 1998), Praxair developed a continuous system which uses the DPCD process as a non-thermal alternative to thermal pasteurization (Connery et al. 2005). This system has been commercialized under the Trade Mark “Better Than Fresh (BTF).” To date, Praxair has constructed four mobile BTF units for processing about 1.5 liters per minute for demonstration purposes. In addition, a commercial scale unit of 150 liters per minute was also constructed (Connery et al. 2005) and tested at an orange juice processing plant in Florida. There are other commercialization efforts. The excellent taste of the juice processed with this new technology was demonstrated in three independent sensory panels that compared juice treated with this system to that of fresh squeezed juice. In all the tests, no difference could be detected. It is important that CO2 is completely saturated in the juice if DPCD is to be successful. Saturation (equilibrium solubility) depends on the pressure, temperature, and composition of the juice. Until recently, the exact amount of CO2 to be used in DPCD processing was unknown since solubility data was unavailable at different pressures, temperatures, and juice compositions, and an excess amount was used. To optimize the use of CO2 in this non-thermal process, new equipment has been developed to measure the solubility of CO2 in liquid systems and juices. The objective of this paper is to present a general review of the applications of DPCD to citrus juices and to introduce the use of new equipment developed at the University of Florida to determine the solubility of CO2 in citrus juices.
