OBJETIVO: Avaliar a composição de ácidos graxos de alguns alimentos industrializados disponíveis no mercado brasileiro nos quais houve redução da quantidade de ácidos graxos trans. Verificar também se estes alimentos atendem às quantidades recomendadas de consumo de gordura saturada, após redução de gordura trans. MÉTODOS: Alimentos industrializados (margarina cremosa A e B, margarina com fitosterol, biscoito doce recheado, biscoito salgado sem recheio, batata frita e lanche com hambúrguer de fast food multinacional com alegação de 0% de gordura trans foram adquiridos em pontos comerciais e analisados em cromatógrafo gasoso. RESULTADOS: Apesar da redução nas quantidades de ácidos graxos trans, os alimentos analisados contêm grandes quantidades de gorduras saturadas principalmente o ácido palmítico. Além disso, alguns dos alimentos estudados apresentam uma razão n-3/n-6 fora do recomendado para a prevenção da aterosclerose. CONCLUSÃO: O consumo irrestrito desses alimentos tem forte potencial deletério para a saúde. O rótulo de ausência de ácidos graxos trans deve ser visto com cuidado e não significa uma liberação para o consumo irrestrito desses alimentos.; OBJECTIVE: To evaluate the composition of fatty acids in some foods available in the Brazilian market in which there was a claimed reduction in the amount of trans fatty acids. Also evaluate whether these foods meet recommended amounts for saturated fat consumption...

OLIVEIRA, P. B. Consumo de adoçantes e produtos dietéticos por indivíduos com diabetes mellitus tipo 2, atendidos pelo Sistema Único de Saúde em Ribeirão Preto SP. 2009. 84 f. Dissertação (Mestrado em Saúde na Comunidade). Faculdade de Medicina de Ribeirão Preto-USP. Devido às suas complicações crônicas, o diabetes mellitus (DM) apresenta impacto considerável como problema de saúde pública pela morbidade, mortalidade e custos no seu tratamento. Para obter um bom controle metabólico, a educação alimentar é um dos pontos fundamentais no seu tratamento. O uso de adoçantes e alimentos dietéticos é importante para as pessoas com DM, apesar de serem dispensáveis na alimentação. Este setor cresceu nos últimos anos e atualmente 35% dos lares brasileiros consomem algum tipo de produto light ou diet. Diante das dificuldades e do pouco conhecimento dos indivíduos com DM sobre o uso destes produtos, verificou-se a necessidade de coletar informações sobre o assunto para subsidiar programas educativos. Este estudo tem como objetivo analisar o consumo de adoçantes e produtos dietéticos por indivíduos com diabetes tipo 2 (DM2), atendidos pelo Sistema Único de Saúde em Ribeirão Preto-SP. Os dados foram obtidos por meio de um questionário envolvendo variáveis sóciodemográficas...

Cada vez mais se associa o consumo de frutas e vegetais à prevenção do câncer, doenças cardiovasculares, osteoporose e diabetes por serem excelentes fontes de compostos fitoquímicos com ação antioxidante que evitam o estresse oxidativo e seus efeitos. Os carotenóides, compostos fenólicos (inclui flavonóides e antocianinas) e ácido ascórbico são os compostos antioxidantes mais abundantes em frutas e vegetais. Entretanto, na primeira infância o consumo de frutas e vegetais in natura tem sido substituído por alimentos industrializados na forma de alimentos infantis ("baby-food"). Como o teor destes compostos antioxidantes presentes em produtos infantis a base de frutas e vegetais comercializados no Brasil ainda não foram determinados, o escopo deste trabalho foi analisar os teores de carotenóides, fenóis, flavonóides e ácido ascórbico e com o uso dos métodos ABTS e DPPH foi medido a atividade anti radical livre destes produtos. Além disso, foi avaliado o efeito do aquecimento em microondas sobre os teores dos compostos antioxidantes. Foram analisadas papinhas de ameixa, goiaba, maçã, pêra, banana e sopinhas de cenoura e mandioquinha adquiridas no comercio da cidade de Campinas, estado de São Paulo. A maior concentração de carotenóides totais foi observada na papinha de cenoura (6...

OBJECTIVE To evaluate the consumption of ultra-processed foods, its associated factors, and its influence on nutrient intake in young adults. METHODS In 2004-2005, the individuals belonging to the Pelotas birth cohort of 1982 were identified for a home interview. A total of 4,297 individuals were interviewed and 4,202 individuals were included in the study (follow-up rate of 77.4%). Diet was assessed using a questionnaire on dietary intake and the percentage of daily caloric intake attributed to ultra-processed foods as well as the intake of macro- and micronutrients were estimated. The association between cohort characteristics and the consumption of ultra-processed foods was assessed using linear regression. Analysis of variance and Pearson’s Chi-square test were used to evaluate the association between the quintiles of the consumption of ultra-processed food, nutrient intake and adequacy of nutrient intake, respectively. RESULTS The consumption of ultra-processed foods corresponded to 51.2% of the total caloric intake. The consumption of ultra-processed foods was higher among women, individuals with higher education, and individuals who were never poor and eutrophic. The increased consumption of ultra-processed foods was positively correlated with the consumption of fat...

The energy value of foods as well as energy requirements of dogs and cats is currently expressed in terms of metabolizable energy (ME). The determination of ME content of foods requires experimental animals and is too expensive and time consuming to be used routinely. Consequently, different indirect methods have been proposed in order to estimate as reliably an accurately as possible the ME content of pet food. This work analyses the main approaches proposed to date to estimate the ME content of foods for cats and dogs. The former method proposed by the NRC estimates the ME content of pet foods from proximal chemical analysis using the modified Atwater factors, assuming constant apparent digestibility coefficients for each analytical fraction. Modified Atwater factors systematically underestimate the ME content of low-fibre foods whereas they overestimate those that are high in fibre. Recently, different equations have been proposed for dogs and cats based in the estimation of apparent digestibility of energy by the crude fibre content, which improve the accuracy of prediction. In any case, whatever the method of analysis used, differences in energy digestibility related with food processing and fibre digestibility are unlikely to be accounted for. A simple in vitro enzymatic method has been recently proposed based in the close relationship that exist between energy digestibility and organic matter disappearance after two consecutive enzymatic (pepsin-pancreatin) incubation of food sample. Nutrient composition and energy value of pet foods can be also accurately and simultaneously predicted using near infrared reflectance spectroscopy (NIRS).

Functional foods have been the topic of considerable interest in the food and nutrition industry for years, but the term currently lacks a common definition. A practical definition adopted here includes products, in food or drink form, that influence specific functions in the body and thereby offer benefits for health, well-being, or performance beyond their regular nutritional value. This paper first discusses the economic opportunities from functional foods, and then discusses challenges and success factors in the sector. The paper concludes that developing countries can enjoy the benefits of the functional food sector to expand options for producers and to promote growth in the sector through partnerships between research centers, private entrepreneurs, and indigenous communities.

Consumption of fish or fish oils rich in the n-3 long chain PUFA EPA and DHA may improve multiple risk factors for CVD. The objective of this study was to determine whether regular consumption of foods enriched with n-3 long-chain PUFA can improve n-3 long-chain PUFA status (erythrocytes) and cardiovascular health. Overweight volunteers with high levels of triacylglycerols (TG; >1.6 mmol/l) were enrolled in a 6-month dietary intervention trial conducted in Adelaide (n 47) and Perth (n 39), and randomised to consume control foods or n-3-enriched foods to achieve an EPA + DHA intake of 1 g/d. Test foods were substituted for equivalent foods in their regular diet. Erythrocyte fatty acids, plasma TG and other CVD risk factors were monitored at 0, 3 and 6 months. There were no significant differences between groups for blood pressure, arterial compliance, glucose, insulin, lipids, C-reactive protein (CRP) or urinary 11-dehydro-thromboxane B2 (TXB2) over 6 months, even though regular consumption of n-3-enriched foods increased EPA + DHA intake from 0.2 to 1.0 g/d. However, the n-3 long-chain PUFA content of erythrocytes increased by 35 and 53 % at 3 and 6 months, respectively, in subjects consuming the n-3-enriched foods. These increases were positively associated with measures of arterial compliance and negatively associated with serum CRP and urinary 11-dehydro-TXB2 excretion. Sustainable increases in dietary intakes and erythrocyte levels of n-3 long-chain PUFA can be achieved through regular consumption of suitably enriched processed foods. Such increases may be associated with reduced CV risk.; Karen J. Murphy...

OBJECTIVE To evaluate the impact of consuming ultra-processed foods on the micronutrient content of the Brazilian population’s diet.METHODS This cross-sectional study was performed using data on individual food consumption from a module of the 2008-2009 Brazilian Household Budget Survey. A representative sample of the Brazilian population aged 10 years or over was assessed (n = 32,898). Food consumption data were collected through two 24-hour food records. Linear regression models were used to assess the association between the nutrient content of the diet and the quintiles of ultra-processed food consumption – crude and adjusted for family incomeper capita.RESULTS Mean daily energy intake per capita was 1,866 kcal, with 69.5% coming from natural or minimally processed foods, 9.0% from processed foods and 21.5% from ultra-processed foods. For sixteen out of the seventeen evaluated micronutrients, their content was lower in the fraction of the diet composed of ultra-processed foods compared with the fraction of the diet composed of natural or minimally processed foods. The content of 10 micronutrients in ultra-processed foods did not reach half the content level observed in the natural or minimally processed foods. The higher consumption of ultra-processed foods was inversely and significantly associated with the content of vitamins B12...

OBJECTIVE To assess the impact of consuming ultra-processed foods on the nutritional dietary profile in Brazil.METHODS Cross-sectional study conducted with data from the module on individual food consumption from the 2008-2009 Pesquisa de Orçamentos Familiares (POF – Brazilian Family Budgets Survey). The sample, which represented the section of the Brazilian population aged 10 years or over, involved 32,898 individuals. Food consumption was evaluated by two 24-hour food records. The consumed food items were classified into three groups: natural or minimally processed, including culinary preparations with these foods used as a base; processed; and ultra-processed.RESULTS The average daily energy consumption per capita was 1,866 kcal, with 69.5% being provided by natural or minimally processed foods, 9.0% by processed foods and 21.5% by ultra-processed food. The nutritional profile of the fraction of ultra-processed food consumption showed higher energy density, higher overall fat content, higher saturated and trans fat, higher levels of free sugar and less fiber, protein, sodium and potassium, when compared to the fraction of consumption related to natural or minimally processed foods. Ultra-processed foods presented generally unfavorable characteristics when compared to processed foods. Greater inclusion of ultra-processed foods in the diet resulted in a general deterioration in the dietary nutritional profile.

Comunicação científica por convite.; Traditional foods are the key elements that differentiate the dietary patterns of each country. In most countries, there is limited information on the nutritional composition of such foods, therefore, there is a need to investigate, register and promote traditional foods. These foods are also a valuable contribution to the development and economic sustainability of rural areas and preservation of biodiversity. One of the aims within BaSeFood project is to provide new data on the nutritional composition of traditional foods of plant origin from six Black Sea area countries (Bulgaria, Georgia, Romania, Russian Federation, Turkey and Ukraine) to promote their sustainable development and exploitation. Thirty-three traditional foods were selected per food group and country taking into account namely food biodiversity and food composition data. Chemical analyses to determine the nutritional composition of the selected traditional foods were performed and the data were fully documented and evaluated according to EuroFIR guidelines and standardised procedures. To assure the quality of analytical results accredited laboratories or laboratories with successful participation in proficiency testing schemes were chosen. Information on food description...

OBJECTIVE: To assess the Na content reported on the labels of processed foods sold in Brazil that are usually consumed as snacks by children and adolescents. DESIGN: Cross-sectional study that assessed Na content and serving size reporting on processed food labels. SETTING: A supermarket that is part of a large chain in Brazil. SUBJECTS: All foods available for sale at the study's location and reported in the literature as snacks present in the diets of Brazilian children and adolescents. RESULTS: Of the 2945 processed foods, 87% complied with the reference serving sizes, although variability in reporting was observed in most of the food subgroups. In addition, 21% of the processed foods had high Na levels (>600 mg/100 g) and 35% had medium Na levels (>120 and ≤600 mg/100 g). The meats, oils, fats and seeds groups as well as the prepared dishes had higher percentages of foods classified as high Na (81%, 58% and 53%, respectively). CONCLUSIONS: Most of the processed foods had high or medium Na content. We emphasize the importance of revising Brazilian nutrition labelling legislation to standardize reference serving sizes to avoid variation. Besides, we point out the potential for reducing Na levels in most processed foods, as evidenced by the variability in Na content within subgroups. Finally...

For the average American. the words "radiation" and "irradiation" are apt to conjure up images of nuclear weapons. radioactive waste, x-rays. and other unpleasant materials associated with health dangers. Yet these words are also displayed on the labels of food products treated with a irradiation process which made the foods safer for consumers to eat. Food irradiation. currently approved for use on several foods, kills microorganisms and insects which could pose substantial health risks to consumers. Irradiation can also be used to retard spoilage and ripening of fruits and ~'egetables to increase their shelf life. Despite its potential benefits, irradiation and the labeling of irradiated foods has been a subject of controversy since its inception. Since 1966, the Food and Drug Administration ("FDA") has required irradiated foods to be labeled as such, but because the initial foods approved for irradiation treatment were limited to potatoes and wheat, the process was not widely publicized. In 1986. however, FDA expanded the list of approved foods to include fruits. vegetables, and spices, and revised its labeling regulations to require that irradiated products be labeled at both the wholesale and the retail level. The promulgation of these guidelines drew criticism from the food industry. Congressmen...

In many countries around the world, support for local agriculture has been a burgeoning issue involving the development of the local foods movement as an alternative marketing. This study investigated ethnic and geographic differences with respect to the consumers' perceptions of local foods in Indonesia. Semistructured interviews were conducted to examine consumers' views of local foods. “Location,” “quality,” and “price” were found to be the most salient characteristics of local foods. The idea of village was associated with the meaning of “local.” Although the respondents' levels of awareness of local foods were high, further education and dissemination of the national policy on local foods was urgently needed.; Poppy Arsil, Elton Li, Johan Bruwer

Objective: To assess differences in functional foods consumption between European countries. Design: Systematic review. The literature search was conducted in Medlars Online International Literature (MEDLINE), via PubMed© and Scopus. Twenty two studies were identified to examine the differences in functional food consumption between European countries. Results: Figures on consumers of functional foods reveal differences across European countries. Functional foods are popular in most of European countries like Finland, Sweden, the Netherlands, Poland, Spain and Cyprus, but not so in other countries like Denmark, Italy and Belgium. A high percentage of adolescents in the European Mediterranean countries (Spain and Cyprus, but not Italy) consume functional foods. Evaluation of functional foods consumption according to gender is difficult, because results differ from one study to another. Conclusions: Functional foods have become very popular in Europe in recent years, but still huge differences exist between Europeans on consumption of functional foods. Further research is needed to find out the reasons behind these differences and to understand consumers' needs for functional foods.

Knowledge of the amino acid composition of foods is essential to calculate their chemical score, which is used to predict protein quality of foods and diets. Though amino acid composition of many foods is reasonably well established, better knowledge is needed on native foods consumed in different regions and countries. This paper presents the amino acid composition of different presentations of raw and processed foods produced and consumed in Mexico. The amino acid composition was determined using Beckman amino acid analyzers (models 116 and 6300). Tryptophan was determined using the Spies and Chambers method. Of the different foods analyzed, some comments are made on native or basic foods in Mexico: Spirulin, where lysine is the limiting amino acid, with a chemical score of 67%, is a good source of tryptophan (1.16g/16 gN); amaranth contains high levels of sulphur amino acids (4.09 to 5.34 g/16gN), with a protein content of 15 g/100g; and pulque, a Pre-Hispanic beverage that contains high levels of tryptophan (2.58 g/16 gN) and sulphur amino acids (2.72 g/16 gN). Finally, insects are good sources of sulphur amino acids and lysine.
