Abstract The Food Guide for the Brazilian Population (GAPB) is an official document that addresses principles and recommendations for an adequate and healthy diet, and it is configured as a support tool for food and nutrition education actions. This article aims to analyze the guide content, which is one of the main instruments of public policies related to food in Brazil, in the light of the concepts of social theory, especially theories of modernity, identity, and risks. In the detailed analysis of the guide content, we found that the document considered the cultural and biological food diversity of Brazilian regions. It is based on food not on nutrients, making illustrative recommendations easy to public understanding. It avoided food risks, considering the issue of acquiring adequate and healthy food. However, two risks were not addressed: the problem of processed and ultra-processed foods (PU); and the omission of warnings regarding transgenic foods (GMOs). Although the guide has been designed in an innovative way, stimulating time, attention, and companionship at the table, the GAPB needs revision.

RESUMO

The aim of this study was to analyze the reproductive behavioral responses in Australian Merino rams, to identify those related to a faster training for semen collection with an artificial vagina. Eight Australian Merino rams, aged 1.5 years and with no prior sexual experience, were randomly selected from an extensively grazed flock. One immobilized ewe with no hormone stimulation was used for rams to sexually interact and mount. The frequencies of approaching, sniffing, flehmen, pushing, pawing with chin resting, and tongue flicking were recorded during eight training and three post-training assessments periods. In addition, the duration of sniffing and flehmen responses, as well as the time from when the ram started to approach the ewe until the mount with ejaculation (completed mount) were recorded. Descriptive, correlation, and modeling analyses were performed. Amongst the rams, four mounted the ewe and ejaculated for the first time during the training phase, and three mounted and ejaculated for the first time after the training phase. The remaining ram mounted the ewe and ejaculated for the first time during the post-training evaluation in the following year. A great variability in the behavior repertoire was observed among rams. The correlation analysis indicated that the completed mount was associated with the behaviors during the approaching response. The expression of the sniffing response decreased between the training phase and post-training evaluation, while the responses of pushing the ewe and tongue flicking ceased to occur. Pawing the side of the ewe with the chin resting on the back of the ewe and flehmen responses, however, continued between the training and post-training phases. This led to a decrease in the time from when the ram started to approach the ewe until the completed mount. It is concluded that the responses of approaching the ewe, pawing the side of the ewe with chin resting on the ewe, and sniffing of the ewe (the latter occurring only during the training phase) are behavioral indicators that could be used for selection of easy-to-train rams for purposes of semen collection with an artificial vagina.

RESUMO

Aims: To identify the effect of adjuvant antineoplastic treatment on body weight change of women with breast cancer.METHODS: A non-randomized clinical study included women with a recent surgical diagnosis of breast cancer, admitted tothe Maternidade Carmela Dutra hospital in Florianópolis, Santa Catarina, southern Brazil, between October 2006 and July2008. Food intake, weight, body mass index, hip circumference, waist circumference and other variables were measuredbefore (baseline) and after the adjuvant antineoplastic treatment (pos-treatment). A mixed effects linear regression modelwas used to estimate the longitudinal changes occurring in weight.Results: The sample comprised 53 patients. A significant increase (P<0.05) was observed in body weight (2.81 kg), bodymass index (1.08 kg/m2), hip circumference (3.62 cm) and waist circumference (1.93 cm). In relation to diet, there was asignificant increase (P<0.05) in the intake of energy (272.7 kcal), total fat (11.2 g) and polyunsaturated fatty acids (5.4 g).The final regression model for the change in body weight demonstrated that the women who were exposed to chemotherapytreatment, and to chemotherapy associated with radiotherapy, had the largest mean increase in body weight (2.47 kg and 5.21kg, respectively). Socio-economic, demographic and nutritional factors were not associated with the increase in body weight.Conclusions: Weight gain was associated with chemotherapy treatment either alone or in combination with radiotherapy.

Objetivos: Identificar o efeito do tratamento antineoplásico adjuvante sobre a mudança de peso corporal em mulheres com câncer de mama. Métodos: Um estudo clínico não randomizado incluiu mulheres com diagnóstico cirúrgico recente de câncer de mama, admitidas no hospital Maternidade Carmela Dutra em Florianópolis, Santa Catarina, entre outubro de 2006 e julho de 2008. Os dados de consumo alimentar, peso corporal, índice de massa corporal, circunferência do quadril, circunferência da cintura e outras variáveis, foram avaliados antes (basal) e depois do tratamento antineoplásico adjuvante (pós-tratamento). Um modelo de regressão linear de efeitos mistos foi utilizado para estimar as mudanças longitudinais que ocorreram no peso corporal. Resultados: A amostra foi composta por 53 pacientes. Foi observado um aumento significativo (P<0,05) no peso corporal (2,81 kg), índice de massa corporal (1,08 kg/m2), circunferência do quadril (3,62 cm) e circunferência da cintura (1,93 cm). Em relação aos aspectos dietéticos, houve um significativo aumento (P<0,05) na ingestão de energia (272,7 kcal), gorduras totais (11,2 g) e ácidos graxos poliinsaturados (5,4 g). O modelo final para a mudança no peso corporal demonstrou que as mulheres as quais foram expostas ao tratamento quimioterápico, e quimioterápico associado ao radioterápico, tiveram um maior aumento médio no peso corporal (2,47 kg e 5,21 kg, respectivamente). Os fatores socioeconômicos, demográficos e nutricionais não foram associados com o aumento no peso corporal. Conclusões: O aumento de peso esteve associado com o tratamento quimioterápico sozinho ou em combinação com o tratamento radioterápico.

RESUMO

PURPOSE: To investigate changes in the dietary consumption as well as the influence of the general characteristics, of the sociodemographic, clinical and nutritional factors, and of the antineoplastic therapy on the changes in the energy intake of women from southern Brazil, before and after adjuvant therapy for breast cancer. METHODS: A non-randomized clinical study was conducted on 53 patients at a hospital of the public health network. Dietary information was collected with a food frequency questionnaire. A mixed-effects linear regression model was used to evaluate the factors that influenced longitudinal alterations of energy intake. RESULTS: A significant increase was observed in daily energy intake of fats, calcium, iron, copper, polyunsaturated fatty acids, omega 6 and omega 3, and a significant decrease in vitamin B2 intake. The final regression model for the change in energy intake showed an average increase of 19.2 kcal/month. Fruit and legume consumption showed the highest association with energy intake, with each 100 g consumed resulting in an average increase of 68.4 and 370.5 kcal, respectively. Women in the 51 to 60 year age range consumed 403.5 kcal less than those in the 31 to 50 year age range. CONCLUSION: There was an increase in energy intake during treatment and the increase in the ingestion of fruits and legumes was associated with significant increases in energy intake.

RESUMO

RESUMO OBJETIVO: Investigar alterações no consumo dietético, bem como a influência das características gerais, dos fatores sociodemográficos, clínicos e nutricionais, e do tratamento antineoplásico sobre as mudanças do consumo energético, em mulheres do sul do Brasil, antes e após a realização de terapia adjuvante para o câncer de mama. MÉTODOS: Ensaio clínico não randomizado, conduzido em hospital da rede pública de saúde, com 53 pacientes. Informações dietéticas foram coletadas com questionário de frequência alimentar. Para avaliar os fatores que influenciaram alterações longitudinais da ingestão energética, usou-se modelo de regressão linear de efeitos mistos. RESULTADOS: Houve aumento significativo no consumo diário de energia, de gorduras, cálcio, ferro, cobre, ácidos graxos poli-insaturados, ômega 6 e ômega 3, e uma diminuição significativa da vitamina B2. O modelo final de regressão mostrou aumento médio de 19,2 kcal/mês. As maiores associações com ingestão energética foram frutas e leguminosas, sendo que cada 100 g de consumo destas, resultou um acréscimo médio de 68,4 e 370,5 kcal, respectivamente. Mulheres com idade compreendida entre 51 e 60 anos consumiram 403,5 kcal menos do que aquelas com idade de 31 a 50 anos. CONCLUSÃO: Observou-se que houve aumento na ingestão energética durante o tratamento e que o aumento na ingestão de frutas e leguminosas foi associado com aumentos significativos na ingestão de energia.
