Introdução: a anemia por deficiência de ferro configura-se como um problema epidemiológico da maior relevância. As consequências decorrentes dessa desnutrição acometem toda a população e os grupos materno/infantil são os mais atingidos pela deficiência marcial, sendo aqueles em que as consequências são mais visíveis e graves. Em 1992, o Brasil se comprometeu a diminuir a prevalência da anemia ferropriva em 1/3 do registrado entre gestantes, até o ano 2000. Compromisso postergado para 2004 e expandido para crianças até 59 meses de idade. Dentre os métodos de intervenção disponíveis para o controle da deficiência de ferro, a fortificação das farinhas de trigo e de milho com o mineral foi a escolhida, devido o trigo ser consumido por toda a população e ser a fortificação a intervenção que apresenta os resultados mais positivos. Objetivo: com base no consumo de trigo, o objetivo é discutir o potencial da farinha de trigo na alimentação como fonte de ferro, no controle da anemia ferropriva no Brasil. Metodologia: estudo descritivo que se refere exclusivamente ao trigo como veículo do ferro. Para obtenção dos dados relativos ao trigo foi estabelecido contato com as empresas do setor período de maio a junho de 2010 e foram coletadas informações veiculadas pela internet. Resultados e discussão: os pré-requisitos para um programa efetivo de fortificação incluem: compromisso a longo prazo, fonte de ferro biodisponível compatível e alimentos adequados, de acordo com a legislação vigente. Em relação ao consumo dos derivados do trigo, o indicador elasticidade-renda da demanda mostrou que a variação da renda provoca variação positiva da demanda dos derivados fortificados. Todos os dados referentes à produção de farinha de trigo, à aquisição de seus derivados, aos números de moinho por região e às padarias indicam como esta estratégia se mostra diferenciada para cada região. Segundo os dados do estudo, a região Norte é a que menos se beneficia desta estratégia de fortificação, ao contrário das regiões Sul e Sudeste do país. Conclusão: houve um aumento na fabricação de pão industrial, bolo industrial e massas instantâneas no Brasil entre o período estudado, e uma redução na moagem de farinha de trigo neste mesmo período. Considerações Finais: a eficácia do programa não é uma garantia de sua efetividade. Para conseguir a efetividade pressuposta seria necessário garantir que o produto fortificado fosse ingerido em quantidade e em frequência adequados, para transformar o alimento em fonte de ferro pela totalidade da população alvo. / Background: Iron deficiency anemia sets an epidemiological problem of greater importance. The consequences of malnutrition affecting the whole population group and maternal / child is the most affected by disability martial and one in which the consequences are more serious and visible. In 1992, Brazil was a signatory to a document signed by 125 nations that pledged to reduce the prevalence of iron deficiency anemia. Among the methods of intervention available to control iron deficiency, fortification of wheat flour and corn with the mineral was chosen because of the wheat consumed by the entire population and be the fortification intervention that presents the results more positive. Objective: Based on your consumption, the objective is to discuss the potential of wheat flour in food as a source of iron in the control of iron deficiency anemia in Brazil. Methodology: This is a descriptive study that refers only to wheat as a vehicle of iron. To collect data for wheat was first established contact with companies in the industry through their representatives in the period from May to June 2010 and data provided by the Internet. Results and Discussion: The prerequisites for an effective program of fortification include: long-term commitment, consistent source of bioavailable iron and adequate food in accordance with current legislation. In relation to consumption of wheat products, the income elasticity of demand showed that variation in income causes a positive change (r> 1) the demand, so that when income increased population also increases the quantity demanded regardless of price level product. All data related to the production of wheat flour, purchase of derivatives, mill numbers by region and bakeries denote this strategy as shown differently for each region. As seen in this study, the North by the data shown is the least benefit of this strategy to fortify the contrary in the South and Southeast. Conclusion: there was an increase in industrial production of bread, cake and pastries industry in Brazil between the instant the study period, and a reduction in grinding flour in the same period. Final Considerations: the effectiveness of the program is not a guarantee of its effectiveness. To get the assumed effectiveness would be necessary to ensure that the fortified product was consumed in quantity and frequency appropriate to turn the food source of iron for the entire target population.

Master of Science / Department of Food, Nutrition, Dietetics, and Health / Brian L. Lindshield / Fortified-blended foods (FBFs), grain-legume porridges (most commonly corn and soy), are frequently used for food aid purposes. Sorghum and cowpea have been suggested as alternative FBF commodities because they are drought-tolerant, grown locally in food aid receiving countries, and are not genetically modified. The objective of this thesis was to determine the protein quality and iron bioavailability of newly formulated, extruded FBFs in broiler chickens, which have been suggested as a good model for assessing iron bioavailability. Five FBFs were formulated to contain whey or soy protein to compare protein quality, sugar, oil, and an improved micronutrient premix. These included three white sorghum-cowpea FBFs; two were extruded with either whey protein concentrate (WSC) or soy protein isolate (WSC+SPI) added, one was non-extruded (N-WSC). Two others were white sorghum-soy (WSS) and corn-soy (CSB14) FBFs. Two additional white-sorghum cowpea FBFs were reformulated and “over-processed” to contain no sugar, less whey (O-WSC) or soy protein (O-WSC+SPI), and less oil, thus producing a less expensive FBF. Two studies were performed using prepared (Prep) or dry (Dry) FBFs, along with the United States Agency for International Development (USAID) corn and soy blend FBF, CSB+, fed to chickens for 3 and 2 weeks, respectively; food intake, body weights, hemoglobin, and hepatic iron were assessed. In the Prep study, new FBFs significantly increased caloric and protein efficiency compared to CSB+, despite similar food intake and body weight gain. In the Dry study, CSB+ significantly decreased food intake and caloric efficiency, with the exception of O-WSC+SPI, and nonsignificantly reduced body weight gain and protein efficiency compared to new FBFs. CSB+ significantly reduced hepatic iron content compared to all FBFs in the Dry study, and was nonsignificantly decreased compared to new FBFs in the Prep study. In conclusion, sorghum and cowpea FBFs performed similarly to corn and soy FBFs, suggesting these commodities are suitable replacements for corn and soy. Soy protein isolate (WSC+SPI) was an effective alternative to whey protein concentrate (WSC), suggesting SPI can be a less expensive protein supplement in FBFs. Surprisingly, non-extruded sorghum and cowpea (N-WSC) was equally efficacious to extruded WSC. However, N-WSC did not meet viscosity requirements and is not precooked, which limits its viability as an FBF. O-WSC+SPI resulted in poorer outcomes compared to other FBFs, which suggests the protein quality of cowpea may be inferior and the inclusion of whey protein is needed in this formulation, as O-WSC with whey performed similarly to other FBFs. Overall, new FBFs, with the exception of O-WSC+SPI, resulted in improved food efficiency and hepatic iron outcomes compared to CSB+, suggesting they are of higher nutritional quality. However, further research is needed to refine and identify the best FBF formulations.

Introdução: a anemia ferropriva na gestação caracteriza-se como um importante problema de Saúde Pública. A partir de junho de 2004, o governo brasileiro tornou obrigatória a fortificação das farinhas com ferro, atendendo às recomendações internacionais e com intuito de minimizar a anemia na população em geral. Objetivo: estudar a prevalência de anemia em gestantes atendidas em um serviço de pré-natal de uma maternidade social da cidade de São Paulo, antes e após a fortificação das farinhas com ferro. Método: estudo transversal retrospectivo com dados coletados de prontuários de atendimento de pré-natal de 2003 (Grupo Não Fortificado) e 2006 (Grupo Fortificado), de janeiro a maio de 2008. Das 931 gestantes selecionadas, 458 eram do Grupo Não Fortificado (Grupo NF) e 473 do Grupo Fortificado (Grupo F). A anemia foi definida pela concentração de hemoglobina (Hb) menor do que 11g/dL, segundo o critério da Organização Mundial da Saúde. Os dados foram armazenados em duas planilhas de Excel Microsoft 2003 e analisados pelos softwares EpiInfo for Windows e Statistical Package for Social Sciences 16.0. Para o tratamento estatístico, foram utilizados o teste do Qui-quadrado para as comparações entre as variáveis dos dois grupos estudados e a associação da anemia e as suas variáveis relacionadas; e a análise de variância, para a comparação entre as médias da concentração de Hb. O nível de significância adotado foi de 5% (p=0,05). Resultados: dentre aquelas variáveis que se apresentaram semelhantes em ambos os grupos, observou-se que a média da idade das gestantes foi 24 anos, um pouco mais de metade delas vivia com companheiro, menos de 40% exerciam ocupação remunerada. Houve diferença estatística significativa no nível de escolaridade (p<0,001) e na inserção precoce no cuidado de pré-natal (p<0,001), em 2006 (Grupo F). A prevalência de anemia no Grupo NF foi de 29,5% e no Grupo F, 20,9%, diferença estatística significativa (p=0,003). Em relação à época da coleta do exame de Hb, os grupos apresentaram diferença estatística significativa (p<0,001), 42,5% das gestantes do Grupo F e somente 15,9% do Grupo NF realizaram a coleta no primeiro trimestre da gestação, o que provavelmente corroborou para a diminuição de prevalência de anemia do Grupo F, além de melhor escolaridade e início precoce da assistência de pré-natal. A análise de variância mostrou que as médias de Hb não apresentaram diferença estatística significativa (p>0,05), constatando que, aparentemente, não houve efeito da fortificação na concentração de Hb entre os grupos estudados. Conclusão: a prevalência de anemia foi menor no grupo fortificado, mas não foi possível comprovar o efeito da fortificação nos níveis da concentração de hemoglobina das gestantes estudadas / Introduction: iron deficiency anemia during pregnancy is characterized as a major public health problem. Since June 2004, the Brazilian government established that flour was fortified with iron following the international recommendations in order to minimize the anemia in the general population. Objective: To study the prevalence of anemia in pregnant women in an antenatal care service in the city of São Paulo, before and after fortification of flour with iron. Method: A cross sectional study with retrospective data collection from medical records of pregnant women attended in an antenatal care service in 2003 (non-fortified group) and 2006 (fortified group). Data were collected from January to May, 2008. The sample was composed by 931 pregnant women, 458 women were from non-fortified group (Group NF) and the other 473 from fortified group (Group F). It was adopted the anemia definition of World Health Organization, hemoglobin concentration (Hb) < 11g/dl. Data were storaged in two Microsoft Excel spreadsheets, 2003 and analysed by Epi Info and Statistical Package for Social Science 16.0. For statistical treatment it was used the Chi-square test for comparisons between variables of two groups and the association of anemia and its related variables, and analysis of variance for comparison between the average concentration of Hb. The significance level was 5% (p = 0.05). Results: Among those variables that showed similar in both groups, it was observed that the average age of women was 24 years, just over half of them lived with a partner, and less than 40% had paid occupation. The difference was statistically significant higher level of education (p <0001) and greater proportion of women with early inclusion in prenatal care (p <0001) in 2006 (Group F). The prevalence of anemia in the Group NF was 29.5% and in Group F was 20.9%, statistically significant difference (p = 0003). Regarding the time of blood collection to verify the Hb, the groups showed statistically significant difference (p <0001), with 42.5% of pregnant women in Group F and only 15.9% of Group NF performed the collection in the first trimester of pregnancy, which probably confirmed for the lower prevalence of anemia in Group F, in addition to better education and early pre-natal. The analysis of variance showed that the mean Hb do not show a statistically significant difference (p> 0.05), noting that, apparently, there was no effect of fortification on the concentration of Hb between the groups. Conclusion: The prevalence of anemia was lower in the fortified group, but was unable to demonstrate the effect of fortification on hemoglobin levels in pregnant women who were recruited in the study

Purpose of this study was to compare two methods of supplementing diets in order to provide additional protein and calories to increase body weight. The study consisted of two groups from the James H. Quillen Veterans Affair Medical Center Nursing Home Care Unit. Experimental group received foods fortified with increased calories and protein at mealtimes. Control group received nutrition supplements between meals. Fifteen subjects began the study. Analysis of weight change revealed that those in the experimental group had no weight change over the four months. Subjects in the control group gained an average of 4.8 lbs of body weight in the same period. The Mann-Whitney Test was used to determine if the weight changes were significantly different between groups. Analysis indicated that (p-value = 0.2550) there was no significant difference in body weight gain between the groups. A larger sample size would have improved the outcome of the study.

En nuestros días, la alimentación ya no se basa sólo en lo que cocinamos, sino también en lo que ingerimos como complementos. Vivimos invadidos por una gran variedad de productos: vitaminas, aminoácidos, extractos vegetales, omega-3, etc. En el presente trabajo aclaramos algunos conceptos importantes, tales como nutracéuticos, alimentos funcionales y alimentos fortificados, así como la forma de producirlos. / Nowadays, nutrition is not only based on what we cook, but also in what we take as supplements. Many products have invaded us: vitamins, aminoacids, vegetal extracts, omega-3, etc.  In this work we explain some important concepts such as nutraceuticals, functional and fortified foods, and also the way these products are made.

Doctor of Philosophy / Department of Human Nutrition / Brian Lindshield / Fortified blended foods (FBFs), in particular, corn-soybean blend (CSB), are food aid commodities widely used in infant and young children supplementary feeding programs. A United States Agency for International Development (USAID) Food Aid Quality Review report recommended developing novel FBFs using local alternative commodities such as sorghum and improving the nutritional quality of FBFs using extrusion processing. Extruded sorghum-cowpea, sorghum-soy and corn-soy FBFs were developed and compared with the non-extruded FBFs corn-soy blend 13 (CSB13) and corn-soy blend plus (CSB+) using the in-vitro digestion/Caco-2 cell model. Dry FBFs’ iron and vitamin A content ranged from 8.0 to 31.8 mg/100g and 0.54 to 1.67 mg/100g, respectively. Following in-vitro digestion, bioavailable iron and vitamin A levels were determined by measuring Caco-2 cell ferritin and vitamin A levels in response to 12-hour and 4-hour treatments, respectively, with aqueous fractions collected from digested FBFs. Most extruded FBFs’ aqueous fraction iron levels were 2- to 7-fold higher (p<0.05) than CSB13 and CSB+. However, Caco-2 cell ferritin and vitamin A levels were not significantly different among FBFs. These results suggest that consumption of newly developed extruded sorghum-cowpea, sorghum-soy and corn-soy FBFs will result in bioavailable iron and vitamin A levels comparable to traditional non-extruded CSB13 and CSB+. Thus, extruded sorghum-cowpea FBF may be a suitable alternative to corn-soybean based FBFs. Saw palmetto supplements are one of the most commonly consumed products by men with prostate cancer and/or benign prostatic hyperplasia (BPH). Some studies have found significant improvements in BPH with saw palmetto supplementation, whereas others found no benefits. The variation in the efficacy in these trials may be a result of differences in the putative active components, fatty acids and phytosterols, of the saw palmetto supplements. We quantified fatty acids and phytosterols in 20 commercially available liquid, powder, dried berry, and tincture saw palmetto supplements. Liquid saw palmetto supplements contained significantly higher (p<0.05) concentrations of total fatty acids (908.5 mg/g), individual fatty acids, total phytosterols (2.04 mg/g), and individual phytosterols, than the other supplement categories. Our findings suggest that liquid saw palmetto supplements may be the best choice for individuals who want to take a saw palmetto supplement.

Doctor of Philosophy / Food, Nutrition, Dietetics and Health / Edgar Chambers IV / Fortified blended foods (FBFs), which are the mixture of cereals and legumes fortified with micronutrients, have been widely used as supplementary foods for vulnerable populations such as infants and young children in developing countries around the world. The evaluation of current FBFs showed limited evidence on their effectiveness in treating childhood malnutrition, resulting the several recommendations on processing and formulation changes to improve their quality and ability to meet nutritional needs. Sensory properties are one of the important determinants for the success of the new FBFs. Therefore, sensory testing was conducted to determine the potential of novel FBFs to be used as supplementary food compared with FBF currently used in food aid programs. Descriptive sensory analysis was performed on novel FBFs along with the traditional FBF (Corn soy blend plus; CSB+) to determine sensory characteristics of each FBF. Results showed that novel FBFs had more pronounced toasted characteristics and higher sweetness than CSB+, due to the higher temperature during extrusion process and the addition of sugar in the novel formulation. In addition, novel FBFs that had higher amount of legumes (e.g. soybean, cowpea) in their formulations, especially for all sorghum cowpea blends, showed higher intensity in beany characteristics. Sensory shelf-life testing showed that novel FBFs could have shelf lives at least 2 years with no detection of off-note characteristics and these was comparable to the shelf life of the current FBF (CSB+). Sensory testing was also performed with target populations: children who eat the food and care givers who prepare it, during a 20-week field trial to determine the acceptability and preference of novel FBFs and current FBF. Results showed that all novel FBFs were highly preferred or accepted by children, even though, some of them might need longer time and more exposures to allow children to have more experience and be familiar with the food before being satisfied or preferred that food. In contrary, CSB+ that had bland flavor tended not to be well accepted and highly preferred by children compared to novel FBFs. Moreover, giving children more opportunities to consumed food prepared from CSB+ did not help to improve its acceptability or preference. Data from household visits and interview sessions showed that porridges prepared from novel FBFs required less cooking time than CSB+ and no additional ingredients needed to be added compared to CSB+ where sugar and milk were common additions. Finding from this research indicated that novel FBFs have high potential to be used successfully as supplementary food with comparable shelf life, and higher acceptability and preference to FBF currently used in food aid programs. In addition, the simple cooking of novel FBFs make them valuable to caregivers who have limited time and access to energy sources and nutrient-rich ingredients.

The term “functional food” (FF) has a variety of definitions resulting in term ambiguity. It is unclear Registered Dietitians’ (RDs) understanding and practices about FF. A descriptive, cross-sectional study investigated RDs’ perceptions, attitudes and practices regarding FF. A national random sample (n=1800) of RDs was mailed a FF questionnaire, 385 (22%) responded. Given five definitions from food-nutrition authorities, the majority of RDs did not agree on a definition, although three-fourths (n=292, 75.8%) perceived fortified foods as FF. Registered Dietitians agreed FF could improve health (n=266, 69.1%), prevent disease (n=282, 73.2%) and treat clientele (n=246, 63.9%), however were neutral (41.6%) or disagreed (37.7%) FF were herbs, or equivalent to medicine (32.7%, 49.2% respectively). Most RDs (n=290, 75.9%) ate FF; fewer (n=231, 61.4%) professionally recommended them. Nearly all (n=353) indicated interest in learning about FF. Registered Dietitians revealed inconsistencies between their perceptions, attitudes and practices regarding FF. Professional education is needed to resolve discrepancies regarding FF.

Proteins present in these waters can be recovered, reducing their environmental impact and generating an ingredient with application in the food industry. The general objective of this study was to recover proteins from surimi elaboration wash waters, using membrane filtration technology, and use them in fishburger elaboration. Wash waters resulting from tilapia surimi production were pooled and filtered on ultrafiltration membrane (UF, 30 kDa). Determination of pH, total (ST) and fixed solids (SF), total proteins, lipids and electrophoretic analysis were performed in the waters obtained from wash process of surimi (original) and after UF (concentrated and permeated). Oxygen chemistry (COD) was determined in the original waters an in the UF permeate. Spray-dried dehydrated concentrate was analyzed for amino acid profile and carotenoid content. Proteins recovered in the dehydrated concentrate were added in the proportion of 0, 5 and 10% to surimi fishburgers, and final products were evaluated for proximal composition, cooking yield, sensory analysis and acceptability index (IA). Physical and chemical data of the original concentrate and permeate waters and the proximal composition of fishburgers were subjected to an analysis of variance (ANOVA) and means were compared by ...
