Uso de substâncias ergogênicas suplementares nutricionais em praticantes de musculação

Ergogenic substances are all nutritional or pharmacological additional devices which physiologically influence on the individual's performance. Currently, the practice of physical exercises that modern gyms have is growing and embracing a new recreational space for the population. In particular, for the male audience, weight training; and for the female audience, aerobic gymnastics. This study has the objective of explaining the importance of ergogenic resources in the physiological and psychological planes, emphasizing the point that supplementation is really valid and beneficial. To achieve the objective of the study, a literature review will be carried out, searching for scientific articles published in books, magazines and online newspapers that address some issues that cut across the thematic proposed in this work. From the point of view of Sport Psychology, the issues discussed on body image and emotional changes have concerns professionals of this area, but the literature suggests it is unnecessary the use of ergogenic substances to the concreteness of that purpose. Supplements of any kind will not be enough to transform the psychological and physiological aspects, the way the media assume conclusively. Thus, with our documentary research, we started a provocation that feeds new studies in the area. We conclude that supplementation is a resource that should be used in the final occasion, that is, if the bodybuilders (non-athletes) have time to be nourished from the normal diet, the use of supplements like whey and creatine, are not needed. Used appropriately supplements do not result in physiological damage, however, can contribute beneficially to the individual's nutrition, thus the abusing dosages, in addition to financial loss, can cause damage to the body

Digestibilidade do amido e disponibilidade de ca e p em alimentos energéticos extrusados para a tilápia do nilo (Oreochromis niloticus)

Apparent digestibility coefficients (ADC) of starch and calcium (Ca) and phosphorus (P) apparent availability were evaluated in five cereal grain products and byproducts (corn, wheat meal, rice grain, rice bran and sorghum) for Nile tilapia. Chromic oxide was used as an external digestibility marker. The highest Ca and P apparent availability, respectively, were obtained for rice grain (43.03 and 64.79%), sorghum (39.89 and 58.09%) and corn (22.18 and 19.48%), while rice bran (-31.49 and 3.25%) and wheat meal (5.80 and 1.18%) showed the lowest values. Starch digestibility varied between 99.45 and 95.59% among the evaluated ingredients. This high ADC of starch observed in this study confirms that Nile tilapia is able to efficiently digest and utilize complex carbohydrates.

Avaliação nutricional e conformidade da rotulagem de “petiscos” consumidos por crianças à legislação brasileira

Label is every and any information regarding to a product that is transcribed in its package. For the consumer it is through the nutritional information tables contained in the labels that there is access to data such as quantity and percentage of nutrients contained in foods. Through this knowledge, it is possible to make healthier food choices, minimizing the negative effects related to poor nutrition in the population, especially among children, the most critical rate of obesity incidence. The aim of this study was to evaluate the appropriateness of the labels of some foods consumed by children in relation to the Recommended Daily Intake (RDI) and verify that the general aspects of the labels were in accordance with Brazilian regulations. Five products were selected like snacks, corn snacks, snacks, peanut, peanuts, potato snacks and biscuit recipes. The labels of different brands of each snack were analyzed using the Checklist of Labelling, which is based on RDC No. 259 and RDC No. 360. The nutritional adequacy of nutrients from these foods (carbohydrates, protein, total fat, saturated fat, trans fat, dietary fiber and sodium) was evaluated in relation to that recommended by the RDA for children 4-8 years old. There was small percentage of mistakes in the labels of the analyzed foods, about 12%, being the presence of words that induce the consumers to the misunderstanding the irregularity with larger predominance, present in 25% of the labels. Other items in disagreement were the incomplete specification of the addictive ones alimentary in the list of ingredients and the absence of instructions about the conservation of the foods after opening the packings, both with percentile of occurrence of 18,75%. The high sodium content found in the nutritional information of food shows that should reduce the consumption of these products among children.

Alimentos tóxicos para cães e gatos

Resíduos de antibióticos e antiparasitários em alimentos de origem animal

O Brasil é considerado um grande produtor e consumidor de carnes, leite e alimentos de origem animal e os medicamentos veterinários têm sido amplamente utilizados na criação dos animais destinados ao consumo humano, com o intuito de prevenir o aparecimento de doenças e também como promotores de crescimento. Os fármacos utilizados para esta finalidade, no entanto, podem ocorrer nos alimentos derivados desses animais tratados, com conseqüências sobre a saúde humana. Além das substâncias utilizadas intencionalmente, a contaminação ambiental ou a presença de contaminantes em rações constitui uma fonte potencial de compostos cuja concentração no alimento final processado pode exceder os limites de segurança estabelecidos para garantir a saúde humana. Com o intuito de promover maior segurança alimentar, no Brasil, foram estabelecidos os programas PNCRC e o PAMVet, que são responsáveis pelo monitoramento da presença de substâncias ilegais (como os antimicrobianos nitrofuranos) e também, visam o controle do Limite Máximo de Resíduos (LMR). O objetivo do presente trabalho é reunir e discutir as informações sobre os principais resíduos e contaminantes de medicamentos veterinários em alimentos de origem animal no Brasil, assim como as publicações referentes às avaliações mais recentes desses produtos alimentícios presentes no mercado brasileiro. Estas informações serão utilizadas para novas discussões relacionadas ao uso adequado de medicamentos veterinários e à proposição de estudos de farmacocinética que poderão fundamentar o estabelecimento do período de carência para esses produtos farmacêuticos.
