The movement of reorientation of nutrition as social and professional practice has been growing and consolidating in recent decades, mainly driven by the persistence of social exclusion and food insecurity globally. In this process, the educational activities in food and nutrition also are located predominantly in traditional models based on technicality and transmission of information. Although allusions are made to authors such as Paulo Freire and the perspective of Popular Education (EP), there remains a gap between what is said and what is done in everyday practice for a transforming action of nutrition food insecure contexts. From an experience in the field of nutrition in the light of EP through the Extension Program "Práticas Integrais de Promoção da Saúde e Nutrição na Atenção Básica – PINAB ", this study aims to analyze how the EP founded a critical act in nutrition. So, we used a qualitative approach with dialectical perspective, built through action research. As a result, we identified categories that point to a critical act in nutrition, namely: engagement and commitment to social reality; share, bond and shared construction; building in the midst of conflict and confrontation of capitalism; education in community groups; overcoming the welfare and reorientation of classic making Nutrition in Food Security and Nutrition Actions (SAN); praxis; and interdisciplinarity. It was also possible to point out some reflections for Food and Nutrition Education (EAN) in the view of the EP, among them, stood out the perception of EAN as a shared construction, mediated through dialogue and popular participation, which requires more than ideas of intellectuals; but the role of popular knowledge. We conclude that the Popular Education has principles, intentions and approaches able to bring elements to overcome the distance between critical debate on nutrition (especially in the field of SAN) and his achievements in the practical field, particularly the educational ones. Even with limits, PINAB experience points sufficient provocations and ways to enunciate the thesis that, effectively, the Popular Education founded a theory and practice of a critical act in nutrition.
O movimento de reorientação da nutrição como prática social e profissional vem crescendo e se consolidando nas últimas décadas, impulsionado principalmente pela persistência da exclusão social e da insegurança alimentar em nível global. Neste processo, as ações educativas em alimentação e nutrição ainda se situam, predominantemente, em modelos tradicionais baseados no tecnicismo e na transmissão de informações. Ainda que sejam feitas alusões a autores como Paulo Freire e na perspectiva da Educação Popular (EP), persiste uma distância entre o que é dito e o que é feito na prática cotidiana para uma ação transformadora da nutrição em contextos de insegurança alimentar. A partir de uma experiência no campo da Nutrição à luz da EP, por meio do Programa de Extensão “Práticas Integrais de Promoção da Saúde e Nutrição na Atenção Básica – PINAB”, o presente estudo tem como objetivo analisar como a EP fundamenta um agir crítico em Nutrição. Para tanto, utilizamos a abordagem qualitativa com perspectiva dialética, construída por meio da pesquisa-ação. Como resultado, identificamos categorias que apontam para um agir crítico em Nutrição, sendo elas: o engajamento e compromisso com a realidade social ; participação, vínculo e construção compartilhada; construção em meio ao conflito e ao enfrentamento do capitalismo; educação em grupos comunitários; a superação do assistencialismo e reorientação do fazer clássico da nutrição nas ações de Segurança Alimentar e Nutricional (SAN) ; práxis ; e a interdisciplinaridade. Foi possível, ainda, apontar algumas reflexões para a Educação Alimentar e Nutricional (EAN) na ótica da EP, dentre elas destacou-se a percepção da EAN como construção compartilhada, mediatizada pelo diálogo e pela participação popular, que requer mais do que ideias de intelectuais; exige o protagonismo do saber popular. Concluímos que a Educação Popular possui princípios, intencionalidades e abordagens capazes de trazer elementos para a superação da distância entre o debate crítico em torno da nutrição (principalmente no campo da SAN) e suas realizações no campo prático, particularmente as educacionais. Mesmo com limites, a experiência do PINAB aponta provocações e caminhos suficientes para enunciarmos a tese de que, efetivamente, a Educação Popular fundamenta uma teoria e uma prática de um agir crítico em Nutrição.

Full textINTRODUCTION: Postmenopausal osteoporosis is associated with significant morbidity, mortality, reduction in quality of life, and increasing health care costs OBJECTIVE: The study objective was to identify the risk factors associated with the occurrence of osteoporosis, in Kenyan Asian women seen at the Aga Khan University Hospital, Nairobi, Kenya since there is no literature on the prevalence of all these risk factors for osteoporosis in a similar middle aged population sample of Kenyan Asian women. METHOD: The study was of a retrospective design and used recall as a basis of data collection. A socio-demographic questionnaire was completed and anthropometric measurements, of height, weight, waist and hip circumference taken. Bone mineral density (BMD) had been measured previously using Quantitative Computed Tomography (QCT) at the lumbar spine, T11 to L4. Nutrient intake was assessed using a validated food frequency questionnaire (FFQ) and physical activity was determined using the Epic Physical Activity Questionnaire 2 (EPAQ2). BMD scans had been done on all study participants from January 2004 to December 2004 and the subjects were aware of their bone status. RESULTS: Risk factors that were identified by being associated with the development of osteoporosis in Asian women were age (p<0.001), waist size (p<0.001), hip size (p<0.001) and BMI (p<0.001), low physical activity (p=0.001) and use of prescription drugs. Seventy two percent of the study sample was using prescription drugs and the effect on bone mass was most likely detrimental. Anti-hypertensive (p=0.002), non steroidal anti inflammatory drugs (p=0.003) and anti-diabetic drugs (p=0.033) had a significant negative association with bone health. Energy, protein, fat and carbohydrate intake in all the groups was above the EAR and comparatively similar. The intake of all the micronutrients in the study group was above the DRI. There were no statistical significant differences in most of the trace element intake between the two groups, apart from iodine, biotin and manganese. No dietary risk factors were identified which impacted adversely on bone health in this group. The impact of gynaecologic history (parity, oral contraceptive use, age of menarche) on BMD was uncertain. The educational level of the study sample was high as 50% of the subjects were graduates and had a relatively better diet. CONCLUSION: As Kenyan Asian women age they experience the menopausal transition and the risk of developing osteoporosis increases. No nutritional factors were identified that were adversely associated with BMD. Low level of physical activity, prescription drugs for chronic diseases like hypertension, asthma, diabetes and arthritis, age, weight and body mass index were identified and found to be adversely associated with bone mineral density. Early detection, and implementation of patient education, physical activity, and a diet rich in all nutrients, will help to slow down the progression of osteoporosis.

Full textThe aim of the PhD thesis is to investigate, analyze and build empirical evidence on the relevance of territorial approaches for addressing the issue of food insecurity, based on the assumption that the ineffectiveness of traditional approaches to food and nutrition security (FNS) stresses the need to shift from one-size-fits-all, entirely top-down and sectoral-based approaches to integrated, context-specific and place-based approaches. The first part defines a conceptual and policy framework for the territorial approach to FNS policies also by interviewing the main experts on the issues of FNS and regional development. The second part aims at filling the FNS gap in terms of information and analytical methods by developing tools and approaches to measure and assess the territorial structural determinants of FNS. In particular, it proposes two different tools: the Territorial Capital Index (TCI) and the Social Accounting Matrix (SAM). The research concluded that FNS is a multi-sectoral and complex socio-economic development issue characterized by a strong territorial dimension which goes far beyond food production and it is the result of dynamic and complex interactions between economic, social, institutional and environmental policies. The combined TCI-SAM approach provides policy makers with comprehensive territorial information to target FNS strategies and policies and to better allocate resources.

The assessment of nutritional status of plants such as rubber is important, as it needs, at all stages of its development of a proper fertilization program, which combined with the correct choice of genetic material, will generate significant productivity gains by avoiding the use unnecessary nutrients. There is a growing demand for natural rubber in the world, and the state of Rio de Janeiro land with favorable conditions for the development of the culture of rubber. Combined with social, economic and environmental importance, rubber cultivation is an alternative economic value to degraded areas and rugged state. The hypothesis is that the adaptation of rubber tree clones is related to genetic material and nutritional demand, reflecting productivity. The objectives of this study were to evaluate the growth of the clones RRIM 600 and PR 255 of Hevea brasiliensis in relation to different levels of nitrogen, potassium and phosphorus. They were tested 28 combinations of nitrogen, phosphorus and potassium for each of the clones, and data were collected from height, diameter and dry weight of plants. Crossing the information, the best results overall were obtained with the treatments 2 (40-50-40), 5 (40-100-40) grams of nitrogen, phosphorus and potassium per plant respectively. Both clones use on average, the same amount of nutrients, but clone RRIM 600 develops more at first, indicating less efficient use of nutrients by clone PR 255, which should not be used on poor soils when compared to the RRIM 600
A avalia??o do estado nutricional de plantas como a seringueira ? importante, pois ela necessita, em todas as fases de seu desenvolvimento, de um correto programa de aduba??o, que aliado ? correta escolha do material gen?tico, ir? gerar ganhos significativos de produtividade evitando o uso desnecess?rio de determinados nutrientes. Existe uma demanda crescente pela borracha natural em todo o mundo, e o estado do Rio de Janeiro terras com condi??es satisfat?rias para o desenvolvimento da cultura da seringueira. Aliado ? import?ncia social, econ?mica e ambiental, o cultivo da seringueira ? uma alternativa de valoriza??o econ?mica para ?reas degradadas e relevo acidentado do estado. A hip?tese testada foi de que a adapta??o dos clones de seringueira est? relacionada ao material gen?tico e ? demanda nutricional, refletindo na produtividade. Os objetivos deste trabalho foram avaliar o crescimento dos clones RRIM 600 e PR 255 de Hevea brasiliensis em rela??o a diferentes doses de nitrog?nio, pot?ssio e f?sforo. Foram testadas 28 combina??es de nitrog?nio, f?sforo e pot?ssio para cada um dos clones, e foram coletados dados de altura, di?metro e massa seca das plantas. Cruzando as informa??es, foram obtidos os melhores resultados no geral com os tratamentos 2(40-50-40), 5(40-100-40) gramas de nitrog?nio, f?sforo e pot?ssio por planta respectivamente. Ambos os clones, utilizam em m?dia, a mesma quantidade de nutrientes, por?m o clone RRIM 600 se desenvolve mais a princ?pio, indicando menor efici?ncia no uso de nutrientes pelo clone PR 255, que n?o deve ser usado em solos pobres, quando comparado ao RRIM 600.

Studies of aluminum tolerance in seedlings aroeira-vermelha (Schinus terebinthifolius R.) were held in a growth chamber in the Department of Plant Science ? Laboratory of Chemistry of Rhizosphere in the Agronomy Institute of University Federal Rural of Rio de Janeiro. Experiments were carried out with different concentrations of aluminum in simple nutrient solution (with calcium) and a complete nutrient solution with concentrations range from 0, 25, 50, 100, 200, 400 and 800 ?M in the solution and in soil Oxisol which was added liming, P, K, and micronutrients. The liming varied from (zero, 500, 1000.2000 and 4000 kg ha-1 and with100, 60, 30 kg ha-1 of phosphorus, potassium and micronutrient Br-12, respectively), and a control treatment without liming, P, K and micronutrients. The evaluations were based on analysis of root growth using the root length parameters, root growth rate, relative and evaluated root elongation also shoot length, dry weight of shoot and root, stem diameter, pH of the rhizosphere and soil . It was found that it is important to time days after sowing, before the transfer of seedlings to the nutrient solution; it is indicated 18 days after sowing for simple nutrient solution and 15 days after sowing for complete solution. Root growth rate and relative root elongation are methods that should be recommended in studies with plants aroeira-vermelha. Complete diluted and balanced nutrient solutions, should be recommended in aluminum toxicity studies in this species rather than simple solutions only with calcium due to low potential for seed storage. Low concentration of Al simple solution led to increase root growth. The root length of Schinus terebinthifolius R. seedlings grown nutrient solutions paralyzed in concentration 131.87 87 ?M of Al. In the simple nutrient solution was only possible to establish the critical level of toxicity using the root growth rate obtaining the value of 88, 42 87 ?M aluminum. Schinus terebinthifolius R. response the application of liming and P, K and micronutrients when grown in a soil Oxisol substrate, and the dosage of 2164.64 kg ha-1 of lime, dosing which was obtained the highest root length. For dry weight of shoot of seedlings, only 1831.50 Kg ha-1 of lime was enough to hit the highest value
Os estudos da toler?ncia ao alum?nio em pl?ntulas de aroeira-vermelha (Schinus Terebinthifolius R.) foram realizados, em c?mara de crescimento no Laborat?rio de Qu?mica da Rizosfera no Departamento de Fitotecnia, Instituto de Agronomia da Universidade Federal Rural Rio de Janeiro. Foram realizados experimentos com diferentes concentra??es de Al em solu??o nutritiva simples (com c?lcio) e completa com concentra??es que variaram de 0, 25, 50, 100, 200, 400 e 800 ?M na solu??o e em solo Latossolo vermelho amarelo onde foi adicionado calagem, P, K, e micronutrientes. As dosagens de calagem variaram de tratamentos com calagem (0, 500, 1000, 2000 e 4000 Kg ha-1, sendo adicionados 100, 60 e 30 Kg ha-1de fosforo, pot?ssio e de micronutriente BR-12 respetivamente), al?m de um tratamento controle, sem calagem, P, K e micronutrientes. As avalia??es foram baseadas na an?lise do crescimento radicular utilizando os par?metros comprimento radicular, taxa de crescimento radicular, elonga??o radicular relativa e avaliados tamb?m o comprimento da parte a?rea, massa seca da parte a?rea e radicular, di?metro do colo, pH da rizosfera e do solo. Foi verificado que ? importante o tempo de dias ap?s a semeadura, antes da transfer?ncia das pl?ntulas para a solu??o nutritiva, sendo indicados 18 dias ap?s a semeadura para solu??o nutritiva simples e 15 dias ap?s a semeadura para solu??o completa. A taxa de crescimento radicular e a elonga??o radicular relativa s?o m?todos que devem ser recomendados em estudos com plantas de aroeira-vermelha. Solu??es nutritivas completas, dilu?das e balanceadas, devem ser recomendadas em estudos de toxidez de alum?nio nesta esp?cie ao inv?s de solu??es simples apenas com c?lcio, devido ao baixo potencial de reserva da semente. Baixas concentra??es de Al na solu??o simples, estimulou o crescimento de raiz. O comprimento de raiz de pl?ntulas de aroeira crescidas em solu??es nutritivas completas paralisou seu crescimento na concentra??o de 131,87 ?M de Al. Na solu??o simples s? foi poss?vel estabelecer o n?vel cr?tico de toxidez utilizando a taxa de crescimento radicular, obtendo o valor de 88,42 ?M de alum?nio. A aroeira respondeu a aplica??o de calagem, P, K e micronutrientes quando crescida em solo Latossolo Vermelho Amarelo, sendo a dosagem de 2164,64 Kg ha-1 de calc?rio a que obteve o maior comprimento radicular. Para a massa seca da parte a?rea somente 1831,50 Kg ha-1 de calc?rio foi suficiente para ser atingido o maior valor.

With the objective to contribute to the study of mineral deficiencies, a survey was conducted through questionnaires, farmers interviews and visits in the properties for a initial diagnosis of the problem. Among the reported outbreaks highlight the signs suggestive of phosphorus deficiency: stiff joints (7.35%), lameness and creaking joints during movement (10.29%) and gnaw and/or chew bones (39.71 %). "Mumps" in calves was reported in three properties (4.41%) suggesting that iodine deficiency or hypoproteinemia. Manifestations of deficiency of cobalt were evidenced by biting and/or chewing tree bark (8.82%), loss of appetite in good pastures (5.88%) and pastures where horses develop only (1.47%). Were also reported signs of deficiencies of zinc, copper and sodium, as well as nonspecific signs (abortion, retained fetal membranes, and retarded growth of calves). The data were collected on soil management and pasture in 20 properties and seven farms were conducted analysis of macro and micronutrient minerals as well as to evaluate soil fertility. The results in soils and pastures showed deficiencies of phosphorus and high amounts of minerals such as iron, zinc, manganese and magnesium which interfere with absorption of copper mainly explaining the signs of this deficiency. The fertile soil condition and fodder were also compromised by the high acidity and high value of aluminum in soils. Failures were observed in the nutritional management of herds and in relation to grazing and management of mineral salt. The opinion of the owners of the herds on mineralization was also elucidated the majority in favor of its use, but admitting mistakes in handling and troughs in the supply of mineral mixtures. In blood serum Mg, Fe and Mn were within normal limits, Ca, Na, K, Co, Cu and Zn below normal and P stood out as being above normal values. Cows compared to calves had higher K and Zn deficiency and comparing the seasons, Co, Fe and Mn were lower at the beginning of the rainy season and Mg and K with smaller values in the early dry season.
Com o objetivo de contribuir com o estudo das car?ncias minerais foi realizado um levantamento atrav?s de question?rios, visitas as propriedades e entrevistas a pecuaristas para um diagn?stico inicial do problema. Dentre as manifesta??es relatadas destacam-se os sinais sugestivos de defici?ncia de f?sforo: articula??es endurecidas (7,35%), claudica??o e ranger das articula??es durante a movimenta??o (10,29%) e h?bito de roer e/ou mastigar ossos (39,71%), ?Papeira? em bezerros foi informada em tr?s propriedades (4,41%) sugerindo defici?ncia de iodo ou hipoproteinemia. As manifesta??es de defici?ncia de cobalto foram evidenciadas por roer e/ou mastigar casca de ?rvore (8,82%), perda de apetite em pastos bons (5,88%) e pastos onde s? equinos se desenvolvem (1,47%). Foram ainda relatados sinais de defici?ncias de zinco, s?dio e cobre, bem como sinais inespec?ficos (abortos, reten??o de placenta e crescimento retardado de bezerros). Foram levantados dados sobre o manejo do solo e pastagens em 20 propriedades e coletas em 7 para an?lise de macro e micronutrientes minerais, bem como avaliada a fertilidade dos solos. Os resultados de solos e pastagens evidenciaram defici?ncias de f?sforo e altos valores de minerais como ferro, zinco, mangan?s e magn?sio que interferem principalmente na absor??o do cobre justificando os sinais dessa defici?ncia. A fertilidade dos solos e a condi??o das forragens tamb?m se mostraram comprometidas pela acidez elevada e altos valores de alum?nio nos solos analisados. Foram evidenciadas falhas no manejo nutricional dos rebanhos e em rela??o ?s pastagens e suplementa??o mineral. A opini?o dos propriet?rios sobre suplement??o mineral dos rebanhos tamb?m foi elucidada sendo a maioria a favor do seu uso, mas admitindo-se os erros no manejo de cochos e no fornecimento das misturas minerais. No soro sangu?neo Mg, Fe e Mn ficaram dentro da normalidade; Ca, Na, K, Co, Cu e Zn abaixo dos valores normais e o P se destacou como estando acima dos valores considerados normais. As vacas em rela??o aos bezerros apresentaram maior defici?ncia de K e Zn e, comparando-se ?s esta??es do ano, Co, Fe e Mn ficaram mais baixos no in?cio da esta??o chuvosa e Mg e K com valores menores no in?cio da esta??o seca.

This work aimed to describe and evaluate the morphogenetic and structural traits, and quality of two clones of elephant grass grazed under rotacional grazing. We used a completely randomized design with three replicates (paddocks) in a split plot, where clones were the whole plot and grazing cycles in a split plot, for evaluate morphogenetic and structural traits, and nutritive value. For evaluate nutrient intake was conducted a test using 10 heifers "testers" in a completely randomized design with 10 replications (animals). Characteristics and structural traits of tillers were similar between the clones. Leaf appearance rate and leaf elongation of aerial tillers were higher for the clone CNPGL 00-1-3 compared to clone CNPGL 92-198-7. Clones showed reduced elongation rate of stem, thus helping to increase the leaf/stem ratio, which is an indication of high nutritional value of pasture clones of elephant grass short stature. Variables studied basal and aerial tillers decreased with grazing cycle, which may be related to the lower temperatures recorded during May, June and July and the lowest rainfall that occurred during the same period. Chemical composition and in vitro digestibility of dry matter (IVDDM) were not affected (P>0.05) by clones and only DM, OM, MM, CP, ADF and CEL were influenced (P<0.05) by cycles of grazing, there wasn?t interaction clone x cycle (P>0.05). Intake was not affected (P>0.05) by clones, however, high values were obtained of intake DM, which can be attributed to low values of NDF, ADF and LIG, and therefore to IVDMD. However, these results demonstrate high quality of forage clones CNPGL 00-1-3 and CNPGL CNPGL 92-198-7.
Objetivou-se, com este trabalho, descrever e avaliar as caracter?sticas morfog?nicas e estruturais, e a qualidade de dois clones de capim-elefante manejados sob lota??o rotacionada. Foi utilizado um delineamento inteiramente casualizado com tr?s repeti??es (piquetes), em esquema de parcelas subdivididas, onde os clones constitu?ram a parcela inteira e os ciclos de pastejo a parcela subdividida, para avaliar as vari?veis morfog?nicas e estruturais, e o valor nutritivo. Para avalia??o do consumo foi realizado um ensaio utilizando-se 10 novilhas de prova, distribu?dos segundo um delineamento inteiramente casualizado com 10 repeti??es (animais). As caracter?sticas morfog?nicas e estruturais de perfilhos basais foram semelhantes entre os clones avaliados. A taxa de aparecimento foliar e taxa de alongamento foliar de perfilhos a?reos foram maiores para o clone CNPGL 00-1-3 em compara??o ao clone CNPGL 92-198-7. Os clones avaliados demonstraram reduzida taxa de alongamento de colmo, contribuindo assim para aumentar a rela??o l?mina/colmo, o que pode ser uma indica??o do elevado valor nutritivo do pasto de clones de capim-elefante de porte baixo. As vari?veis estudadas de perfilhos basais e a?reos decresceram com ciclo de pastejo, o que pode estar relacionado ?s temperaturas mais baixas registradas nos meses Maio, Junho e Julho, assim como a menor precipita??o que ocorreu nesse mesmo per?odo. A composi??o qu?micobromatol?gica e a digestibilidade in vitro da mat?ria seca (DIVMS) n?o foram influenciadas (P>0,05) pelos clones e apenas a MS, MO, MM, PB, FDA e CEL foram influenciadas (P<0,05) pelos ciclos de pastejo, n?o havendo a intera??o clone x ciclo (P>0,05). O consumo n?o foi influenciado (P>0,05) pelos clones avaliados, por?m, foram obtidos elevados valores de consumo de MS, que podem ser atribu?dos aos baixos valores de FDN, FDA e LIG e consequentemente a alta DIVMS. Contudo, esses resultados demonstram a elevada qualidade, da forragem dos pastos dos clones CNPGL 00-1-3 e CNPGL 92-198-7.
