Post-menopause is characterized as the period beginning one year after the permanent cessation of menstrual cycles, which is typically related to medical disorders that, in association with Metabolic Syndrome (MS), represent a set of cardiovascular risk factors. Objective: To assess dietary intake and the prevalence of metabolic syndrome in postmenopausal women, according to the level of physical activity. Methods: The sample consisted of 82 women, evaluated in the Northern Zone of the city of Natal / RN who were participants in the Natal Active Program. People completed a Food Frequency Consumption Questionnaire (FFCQ) and were interviewed about physical activity. Anthropometric measurements and biochemical tests were used to diagnose MS (Metabolic Syndrome). Result: The active women consumed more protective foods (flaxseed, nuts, whole wheat bread, brown rice and olive oil) than inactive women. Risky foods (sugar, crackers, white bread, white rice, margarine and beef) were consumed more by the group of inactive women. The prevalence of MS was higher in inactive women (53.30%) than in physically active women (46.70%). Conclusion: Active post-menopausal women had a higher daily intake of protective foods in relation to cardiovascular disease, while the inactive post-menopausal women had higher intake of risky foods for such diseases

Demand for organic foods within in Brazil are growing, characterizing itself for if constituting in a new strategical segment of commercialization. In this context, the objective of this research was to investigate the variables used by consumers in the purchase decision of organic products, aiming to characterize the level of competitiveness of these products, assisting in the creation of environmental strategies for the development of the activity and contributing in the increment of the knowledge about the subject, that can assist it in the increase of the commercialization and the consumption of these foods. From data collected in the city of Natal/RN, it was used a survey research, of exploratory and descriptive character. The sample was obtained using 401 questionnaires, in which was realized: the Test of Comparison of Averages, Descriptive analysis, analysis of Cluster and Qui-square. The results found in this study indicate that the main reasons for the organic food purchase are the absence of chemical pesticides in the product, followed by the care with own health and of the household. The main characteristics in the consumers of supermarkets, that are associates with purchase frequency of organic foods are the environmental behavior and lifestyle. Among the profile characteristics, gender, age and number of children are associates with the purchase frequency of these foods and the income and level education not showed association

O objetivo deste trabalho foi avaliar o efeito da formulação de rações para frangos de corte, com a utilização de valores de energia metabolizável (EM) dos alimentos determinados por diferentes métodos. O delineamento experimental foi inteiramente casualizado, com quatro tratamentos, que consistiram na formulação de rações baseadas na: em aparente corrigida e em aparente, ambas determinadas pelo método da coleta total com pintos; em aparente corrigida, determinada pelo método da coleta total com galos; e em verdadeira corrigida, determinada pelo método da alimentação forçada com galos. Na fase inicial, foi obtido maior consumo de ração, ganho de peso e melhor conversão alimentar com a formulação baseada na em aparente corrigida (pintos). Durante a fase final, a formulação com em verdadeira corrigida (galos) promoveu maior ganho de peso e melhor conversão alimentar. No período de 1 a 49 dias, as aves alimentadas com as rações formuladas com em aparente corrigida (pintos) tiveram melhor desempenho. As características de carcaça não foram influenciadas pelos tratamentos. Até os 21 dias de idade, deve-se considerar os valores de em aparente corrigida (pintos), para a formulação das rações de frangos de corte; após essa idade, deve-se considerar os valores de em aparente corrigida (galos) ou em verdadeira corrigida (galos).

The present study was conducted to evaluate the intake and digestibility of diets containing increasing levels of byproduct of cashew in sheep. The animals were distributed in a completely randomized design were evaluated in four levels (0%, 20%, 40%, 60%) by product of cashew with four replicates, making up 16 observations. The indicator used was the Purified Lignin and Enriched - LIPE ®. The scorer was orally administered directly into the mouth of the animals, in the form of capsules 250mg/animal/dia for a period of two days and five days of adaptation samples being the same supplied with the aid of a hose polyethylene and a device allowing the release of the capsule in the esophagus of sheep. With the estimate made by the indicator LIPE was observed a reduction for DM, OM, CP, NDF, EE, NFC and MM along the inclusion of byproduct of cashew. The results of nutrient digestibility were not satisfactory with the inclusion of byproduct of cashew, reducing linearly with the inclusion of the diets. The use of increasing levels of byproduct of cashew in the diets of sheep did not provide satisfactory results, it is not feasible to use the animals studied in this experiment

Avaliaram-se o consumo e a digestibilidade aparente dos nutrientes, e o balanço de nitrogênio da silagem de milho e dos fenos de alfafa e de capim- coastcross, em ensaio com ovinos. Foram utilizados 15 animais, sem raça definida, castrados, com peso médio de 47,5 kg, distribuídos em um delineamento em blocos casualizados com cinco repetições. O consumo de matéria seca, em g/Kg0,75, foi influenciado pelos alimentos, registrando-se maior valor (68,06), para os animais que receberam feno de alfafa. Os consumos de fibra em detergente neutro e extrato etéreo foram menores para os animais que receberam silagem de milho. Já os consumos de proteína bruta e nutrientes digestíveis totais, de 201,97 e 643,42 g/dia, respectivamente, foram maiores para os animais alimentados com feno de alfafa. Este resultado deve-se ao fato de o feno de alfafa possuir melhor valor nutritivo e estar associado ao teor mais elevado de matéria seca. As digestibilidades aparentes da matéria seca e proteína bruta, de 56,47 e 73,92%, respectivamente, também foram maiores para os animais que receberam feno de alfafa. O balanço de nitrogênio foi positivo apenas para os animais alimentados com fenos, os quais apresentaram ganhos de peso de 100,79 e 147,62 g/dia para feno de capim-coastcross e feno de alfafa, respectivamente, enquanto que os animais alimentados com silagem de milho apresentaram perda de peso (-34,92 g/dia). Este fato pode ser atribuído a superioridade da composição química dos fenos em relação à da silagem de milho.

Foodborne and waterborne diseases are spread by the consumption of food or water contaminated with bacteria and/or their toxins, viruses, parasites or chemicals. The aim of the research reported here was to establish the spectrum of etiologic agents of foodborne outbreaks at 15 tourist resorts in three geographic regions of the State of Sao Paulo (Brazil). The study was based on the cases reported to the Epidemic Surveillance Center (CVE) of the Public Health Authority of the State of São Paulo (SES), from 2002 to 2005. The tourist centers were chosen at random in three regions of the state (Capital, Interior and Coast) and offered the following attractions: events, agribusiness, cultural history, shopping, town center, gastronomy, health and leisure, sun and sea. Among the bacteria, the results showed that Salmonella spp. were most frequently associated with outbreaks, followed by Shigella spp., enterotoxigenic Escherichia coli, Staphylococcus aureus, Clostridium perfringens, Bacillus cereus and Campylobacter spp. Viruses (Rotavirus and Hepatitis A) played a part in many of the cases, while the frequency of parasites and worm infestations was low in the foodborne disease outbreaks at these resorts. The mixed foods (rice, beans, liver, potatoes, barbecue, juice), fish and poultry were the three commonest vehicles implicated in the outbreaks.
