“…18 Promoting optimal CF practices in developing countries is a global health priority. 19 However, based on previous reports, timely initiation of CF at the 6th month of age in developing countries, such as Ethiopia, Nairobi, and so forth, was usually under 50%. 20 This study first reported the feeding behaviors of children in Myanmar and found inappropriate feeding behaviors that resulted in malnutrition.…”

Abstract. The complementary feeding period is an important time for children's growth and development. This study was conducted to 1) determine the feeding behaviors of 6-to 36-month-old children in Myanmar, 2) explore health effects of feeding behaviors, and 3) determine factors associated with feeding behaviors. A total of 807 children and their mothers (N = 642) were recruited from nine villages in Kachin, Shan, and Kokang, Myanmar. Feeding behaviors and sociodemographic characteristics were investigated using a validated questionnaire. Hemoglobin and anthropometric indicators were measured during the fieldwork. In our sample, 18.6%, 72.7%, and 9.8% of children were introduced to complementary foods (CFs) earlier than 4 months of age, between 4 and 8 months of age, and later than 8 months of age, respectively. For different types of CFs, up to the age of 24.1-36 months, there were still 6.5% and 4.1% of the children who had never been introduced to eggs and meat. Introduction of CFs earlier than 4 months of age was a risk factor for being underweight (age-adjusted odds ratio (OR adjust-age ) = 1.7, 95% confidence interval (CI) = 1.2-2.5) and for stunting (OR adjust-age = 1.6, 95% CI = 1

“…A facilidade de avaliação multifatorial, usando técnicas de modelagem matemática, amplia a gama de conhecimentos para o pesquisador porque fornece ferramentas capazes de correlacionar múltiplos fatores, que no caso da nutrição e alimentação inclui os hábitos alimentares dos indivíduos, as quantidades de nutrientes presentes nas dietas e alimentos, fatores econômicos e culturais das populações de estudo, agricultura local e favorecimento climático para a oferta de alimentos, entre outros 37 . A utilização do delineamento experimental baseado na metodologia de superfície de resposta para misturas foi abrangente e possibilitou a varredura de toda a região estudada na busca da melhor formulação possível, mostrando que os resultados obtidos estão de acordo com a literatura, podendo ser uma ferramenta importante a ser utilizada na terapia nutricional.…”

Recebido em 16/2/07; aceito em 10/8/07; publicado na web em 19/12/07 EFFECT OF MEDIUM-CHAIN TRIGLYCERIDES, FIBER AND CALCIUM ON THE AVAILABILITY OF MAGNESIUM AND ZINC BY AN IN VITRO METHOD AND RESPONSE SURFACE METHODOLOGY. Nutritional therapy with enteral diets became highly specialized in the last years. This work aims to study the effect of the components of a formulation, namely fiber, calcium and medium-chain triglycerides, for dialysability of minerals. Analysis of multiple variables was done using response surface methodology. The level curve showed that the tertiary interaction MCT-fiber-calcium was the one that presented the highest synergism in the formulation. The proportion of 33% MCT, 25% fiber and 42% calcium, gave the best formulation for availability of magnesium.Keywords: magnesium; zinc; availability. INTRODUÇÃOAs formulações enterais são sistemas complexos por terem na sua constituição todos os nutrientes presentes nos alimentos, onde os minerais tendem a sofrer processos de interações e propiciam alterações na absorção de nutrientes, interferindo na qualidade nutricional das dietas enterais [1][2][3][4] . Os alimentos fonte de magnésio são as leguminosas, nozes, amêndoas e vegetais folhosos verdes escuros, mas a sua biodisponibilidade tende a diminuir porque sofre interações com componentes dos alimentos. O mecanismo celular de absorção e sua regulação corporal são ainda mecanismos pouco conhecidos, mas sabe-se que é dependente de nutrientes presentes na dieta alimentar. A biodisponibilidade de magnésio em uma dieta balanceada está estimada em cerca de 40%, e sua maior absorção ocorre no intestino delgado. A absorção do nutriente é reduzida na presença de cálcio, álcool, fosfato, fitatos e gorduras e é estimulada na presença de vitamina D [1][2][3] . O magnésio é necessário para o metabolismo energético e está envolvido na síntese protéica. Participa de mais de cem sistemas enzimáticos, sendo que uma de suas principais funções é mediar o processo de catálise para as reações com fosfato e produção de energia, o ATP [4][5][6] . Os processos fisiológicos da contração muscular e da coagulação sangüínea são dependentes da presença de cálcio e de magnésio, ressaltando a necessidade de se avaliar possíveis interações entre os dois minerais 2,4 . O zinco é um outro mineral importante que deve ser avaliado em dietas enterais. Sua presença é essencial para o metabolismo normal e de grande valor na proteção das células contra radicais livres [7][8][9] . Da ingestão do mineral presente em alimentos e dietas, cerca de 20 a 40% são absorvidos e a diminuição da biodisponibilidade do mineral tem sido associada com os teores de fitatos, quantidades de ferro e compostos de estruturas complexas presentes, como por exemplo as fibras 10 .Por serem nutrientes importantes, buscou-se avaliar a biodisponibilidade de magnésio e de zinco em um estudo de interação em que foram avaliadas as concentrações de triacilglicerídeos de cadeia média (TCMs), de fibra e do cálcio em uma formulação de alimentação enteral, utilizando...

“…The result obtained showed a marked improvement of the goal programming results over that of linear programming. [8] also developed a 4-phase approach for designing optimal population-specific food-based Complementary Feeding Recommendations (CFRs) in which the goal programming techniques were used to select an optimal diet which aimed at providing a desired nutrient content with respect to habitual diet patterns and cost. A hypothetical example was used to illustrate the approach.…”

A Linear Programming DASH diet model for persons with hypertension has previously been formulated and daily minimum cost diet plans that satisfy the DASH diets' tolerable intake level of the nutrients for 1500 mg a day Sodium level and different daily calorie levels were obtained using sample foods from the DASH diet eating plan chart. But the limitation in the use of linear programming model in selecting diet plans to meet specific nutritional requirements which normally results in the oversupply of certain nutrients was evident in the linear programming DASH diet plan obtained as the nutrient level of the diet plans obtained had wide deviations of from the DASH diets' tolerable upper and lower intake level for the given calorie and sodium levels. Hence the need for a model that gives diet plans with minimized nutrients' level deviations from the DASH diets' tolerable intake level for different daily calorie and sodium level at desired cost. A weighted Goal Programming DASH diet model that minimizes the daily cost of the DASH eating plan as well as deviations of the diets' nutrients content from the DASH diet's tolerable intake levels is hereby presented in this work. The formulated weighted goal programming DASH diet model is further illustrated using chosen sample foods from the DASH food chart as used in the work on the linear programming DASH diet model for a 1500 mg sodium level and 2000 calories a day diet plan as well as for 1800, 2200, 2400, 2600, 2800 and 3000 daily calorie levels. A comparison of the DASH nutrients' composition of the weighted Goal Programming DASH diet plans and those of the linear programming DASH diet plans were carried out at this sodium level and the different daily calorie levels. It was evident from the results of the comparison that the weighted goal programming DASH diet plans has minimized deviations from the DASH diet's tolerable intake levels than those of the linear programming DASH diet plans.
