Food habits and sport activity during adolescence: differences between athletic and non-athletic teenagers in Switzerland.

OBJECTIVE: To describe food habits and dietary intakes of athletic and non-athletic adolescents in Switzerland. SETTING: College, high schools and professional centers in the Swiss canton of Vaud. METHOD: A total of 3,540 subjects aged 9-19 y answered a self-reported anonymous questionnaire to assess lifestyles, physical plus sports activity and food habits. Within this sample, a subgroup of 246 subjects aged 11-15 also participated in an in-depth ancillary study including a 3 day dietary record completed by an interview with a dietician. RESULTS: More boys than girls reported engaging in regular sports activities (P<0.001). Adolescent food habits are quite traditional: up to 15 y, most of the respondents have a breakfast and eat at least two hot meals a day, the percentages decreasing thereafter. Snacking is widespread among adolescents (60-80% in the morning, 80-90% in the afternoon). Food habits among athletic adolescents are healthier and also are perceived as such in a higher proportion. Among athletic adolescents, consumption frequency is higher for dairy products and ready to eat (RTE) cereals, for fruit, fruit juices and salad (P<0.05 at least). Thus the athletic adolescent's food brings more micronutrients than the diet of their non-athletic counterparts. Within the subgroup (ancillary study), mean energy intake corresponds to requirements for age/gender group. CONCLUSIONS: Athletic adolescents display healthier food habits than non-athletic adolescents: this result supports the idea that healthy behavior tends to cluster and suggests that prevention programs among this age group should target simultaneously both sports activity and food habits.

Hàbits alimentaris en nens de 8 a 12 anys de la comarca d'Osona

Introducció: La dieta mediterrània és considerada un dels patrons alimentaris més saludables ja que diversos estudis epidemiològics mostren que protegeix front diverses malalties cròniques com ara les malalties cardiovasculars, la diabetis i alguns càncers. Malauradament al nostre país els patrons alimentaris estan canviant a conseqüència de la modernització de la societat i estan portant a l’allunyament del patró de dieta mediterrània. Això és especialment crític entre la població infantil i juvenil, fet que predisposa a que en un futur augmenti la prevalença de malalties cròniques entre la població adulta. Objectiu: avaluar els hàbits alimentaris i l’estat nutricional d’escolars de 8 a 12 anys de la comarca d’Osona. Mètodes: estudi de disseny observacional i transversal. La mostra estava constituïda per 191 escolars de 4rt i 5è d’ensenyança primària d’escoles de la comarca d’Osona. La informació sobre la dieta es va recollir a través d’una enquesta alimentària, un recordatori de 24 hores, un qüestionari de freqüència de consum alimentari i el test KIDMED. Les determinacions antropomètriques que es van realitzar van ser talla, pes, IMC (Índex de Massa Corporal), plec tricipital, perímetre braquial i perímetre abdominal. L’anàlisi estadística de totes les dades es va portar a terme mitjançant el programa estadístic SPSS per Windows versió 12.0. Resultats: quan es valora la qualitat de l’esmorzar, s’observa que només en el 16.8% dels casos la qualitat era bona, en el 68.6% dels casos la qualitat havia de millorar i en el 12.6% era de qualitat insuficient i en el 2.1% era de mala qualitat. També s’observa que la dieta que segueixen és desequilibrada quantitativament, concretament és baixa en hidrats de carboni, rica en greixos i lleugerament elevada en proteïnes. L’anàlisi qualitativa mostra que hi ha un molt baix consum de verdures i hortalisses i de fruita, mentre que s’arriba a les racions recomanades de carnis i d’olis i greixos. El test KIDMED mostra una puntuació mitjana de 7.21±1.96 punts, el que indica que la dieta de la població és de qualitat millorable. Pel que fa a l’estat nutricional s’observa que un 24,6% presenta valors de baix pes i un 17,8% sobrepès o obesitat, el que indica que un 42,4% de la població estudiada presenta un estat nutricional incorrecte. Conclusions: La dieta del col·lectiu estudiat s’allunya de les recomanacions de la SENC (Sociedad Española de Nutrición Comunitaria). Els resultats del test KIDMED indiquen que només un 44% de la població segueix un patró òptim de Dieta mediterrània i l’anàlisi de l’estat nutricional mostra que un 42,4% presenta un estat nutricional incorrecte, sigui per excés o per defecte de pes. Per tant, es fa necessari dissenyar estratègies d’educació alimentària adequades per millorar els hàbits alimentaris dels escolars i aconseguir en un futur un estat òptim de salut.

Holy harlots : authority, gender, and the body in medieval English hagiography

This doctoral dissertation aims at describing the representation of holy harlots (Mary Magdalene, Mary of Egypt, Pelagia, Thai's, Afra of Augsburg) in medieval English hagiography. These saints are unique representatives that combine both extremes of the feminine in the medieval imaginaire: she is both, as a saint, the Virgin Mary, the pure and virtuous woman, and, in her past as a prostitute, Eve, the evil female tempter who led all mankind to destruction. The initial question of this thesis is how did hagiographers negotiate the representation of a formerly sinful, sexually active, long- living woman as an authoritative saint? This thesis aims at finding elements of answer to this question, investigating the intersections between gender and authority in the saints' lives of repentant prostitutes in all the vernaculars of medieval England: Old English, Anglo-Norman, and Middle English. It posits that the portrayal of holy harlots' authority and gender is dependent upon social, religious and literary shifts during the medieval period. My contention is that the harlot's gender portrayal changes over the course of the eleventh and twelfth centuries, due notably to the rise of affective piety and the important influence of the romance genre over hagiography. In Anglo-Saxon England, the harlot's gender changes with the saint's conversion: a woman beforehand, her gender is portrayed after her repentance as ambiguous in order for her to become a saint. Her authority derives from her own sanctity in this case. From the twelfth century onward, however, the harlot, now often turned into a beautiful and landed romance lady, is more and more represented as a woman throughout her life, and becomes after her conversion a Bride of Christ. In this way, the dangerously free woman who roamed the streets and prostituted her body becomes less threatening after her conversion, being (re-)inscribed within the male dominated institution of marriage. She now draws her authoritative stance from her gendered intimacy with Christ: although she submits to Christ as his bride, she also gains greater authority than before by way of her privileged relationship with the Savior.

Hidratos de carbono: actualización de su papel en la diabetes mellitus y la enfermedad metabólica.

BACKGROUND: There is a prevalence of diabetes mellitus (DM), unknown DM and stress hyperglycemia among hospital patients, and the nutritional treatment is a key part of care, where carbohydrates (CH) intake is a controversial issue. There is also a discussion on the increase of prevalence for DM, obesity and metabolic disease with refined CH or sugar. OBJECTIVES: This review examines the recommendations from different scientific societies about the percentage of CH in the total calorie intake of the diabetic patient, the CH value in the glycemic index and glycemic load, the new CH included in enteral formulae and the association of refined CH with the high prevalence of DM and metabolic disease. METHODS: Systematic review of literature using the electronic scientific databases Pubmed, Science Direct, Scielo, Scopus and Medline. CONCLUSIONS: Scientific societies are flexible about the CH intake in the diet of diabetic patients, suggesting to customize it according to each metabolic profile. Using the glycemic index and glycemic load can provide an extra benefit in the postprandial glycemic control. The new diabetes-specific enteral formulae, with fructooligosaccharides, resistant maltodextrins and fructose-free show efficacy in improving the glycemic control, although more controlled and long-term studies are needed. There is still some controversy about the links between sugar intake and DM, obesity and metabolic disease, although this relationship would be more linked to an increase of the total calorie intake than to a specific nutrient. .

Micobiota associada a folhas de bananeira em Cabo Verde

A bananeira tem um elevado valor social e económico para Cabo Verde, desempenhando um papel fundamental na dieta alimentar das populações. Nos últimos anos a produtividade da cultura tem vindo a decair e de entre as causas responsáveis pelo declínio dos bananais incluem-se micoses. Com a finalidade de determinar o possível envolvimento de fungos nas doenças foliares fez-se o levantamento da micobiota associada a necroses foliares. Material foliar com lesões de diversos tipos foi recolhido em bananais de 10 localidades da Ilha de Santiago e observado ou colocado em câmara húmida sobre meio gelosado. As estruturas de fungos detectadas sobre as folhas foram montadas em lactofenol e utilizadas para identificação até ao nível da espécie, dos fungos registados, utilizando para o efeito critérios clássicos em sistemática micológica. Foram identificados 48 táxones, sendo 44 fungos mitospóricos e 4 fungos ascomicetas. Muitos dos fungos identificados não são considerados fitopatogénicos na bananeira, estando referidos como endófitos ou saprófitas na cultura. Os principais fungos patogénicos identificados foram Cladosporium musae, Colletotrichum gloeosporiodes, C. musae, Cordana musae, Deightoniella torulosa, Lasiodiplodia theobromae e Ramichloridium musae. A maioria das espécies apresentou larga distribuição nas zonas de produção amostradas.

Relaciones ontogénicas y espacio-temporales en la dieta del calamar gigante (Dosidicus gigas) en Perú, utilizando un Modelo Aditivo Generalizado

El calamar gigante Dosidicus gigas (d'Orbigny, 1835) es un depredador importante en el ecosistema del Perú. Se postula que el papel del calamar gigante varía teniendo en cuenta la talla, tiempo, hora, temperatura y distribución espacial. Para comprobar esta hipótesis se aplicó un modelo aditivo generalizado (GAM) en datos biológicos de alimentación de 4178 calamares gigantes capturados por la flota industrial pesquera a lo largo del litoral peruano (3ºS a 18ºS) desde 2 a 299 millas náuticas (mn) de distancia a la costa desde el año 2004 a 2009 realizados por el Laboratorio de Ecología Trófica del Instituto del Mar del Perú (IMARPE). La talla de los calamares estudiados fluctuó entre 14 y 112 cm de longitud de manto (LM). En total 43 item-presa fueron registrados, los grupos más importantes fueron los cefalópodos (Dosidicus gigas), Teleosteii (Photichthyidae, Myctophidae y Nomeidae) y Malacostraca crustáceos (Euphausiidae). Las presas principales fueron D. gigas (indicando canibalismo) en términos gravimétricos (% W=35.4), los otros cephalopodos en frecuencia de ocurrencia (FO=14.4), y los eufáusidos en términos de abundancia relativa (% N=62.2). Estos resultados reflejan una alta variabilidad de la dieta, y un espectro trófico similar en comparación con otras latitudes en ambos hemisferios (México y Chile). Los modelos GAM muestran que todas las variables predictoras fueron significativas en relación a la variable respuesta llenura estomacal (p <0.0001). La llenura estomacal fue mayor en los individuos juveniles, también durante la noche hubo mayor consumo, mientras no se reflejaron tendencias en la alimentación con relación a la temperatura superficial del mar (TSM), pero espacialmente se observan cambios en la dieta, aumentando el porcentaje de llenura a medida que esta especie se aleja de la costa. Por lo tanto se concluye que la dieta del calamar gigante depende de la talla y su distribución espacio-temporal.

Chemical defenses in Sacoglossan Opisthobranchs: Taxonomic trends and evolutionary implications

Sacoglossan sea slugs (Mollusca: Opisthobranchia) are one of the few groups of specialist herbivores in the marine environment. Sacoglossans feed suctorially on the cell sap of macroalgae, from which they 'steal' chloroplasts (kleptoplasty) and deterrent substances (kleptochemistry), retaining intracellularly both host plastids and chemicals. The ingested chloroplasts continue to photosynthesize for periods ranging from a few hours or days up to 3 months in some species. Shelled, more primitive sacoglossans feed only on the siphonalean green algal genus Caulerpa, and they do not have functional kleptoplasty. The diet of sacoglossans has radiated out from this ancestral food. Among the shell-less Plakobranchidae (=Elysiidae), the more primitive species feed on other siphonales (families Derbesiaceae, Caulerpaceae, Bryopsidaceae and Codiaceae) and fix carbon, while the more 'advanced' species within the Plakobranchidae and Limapontioidae have a more broad dietary range. Most of these 'advanced' species are unable to fix carbon because the chloroplasts of their food algae are mechanically disrupted during ingestion. Mesoherbivores are likely to be eaten if they live on palatable seaweeds, their cryptic coloration and form not always keeping them safe from predators. Sacoglossans prefer to live on and eat chemically defended seaweeds, and they use ingested algal chemicals as deterrents of potential predators. The most ancestral shelled sacoglossans (Oxynoidae) and some Plakobranchidae such as Elysia translucens, Thuridilla hopei and Bosellia mimetica have developed a diet-derived chemical defense mechanism. Oxynoids and Thuridilla hopei are able to biomodify the algal metabolites. However, the Plakobranchidae Elysia timida and E. viridis, together with Limapontioidea species, are characterized by their ability to de novo synthesize polypropionate metabolites. A whole analysis of kleptoplasty and chemical defenses in sacoglossans may offer a better understanding of the ecology and evolution of these specialized opisthobranchs. In this paper we summarize some of the latest findings, related mainly to Mediterranean species, and offer a plausible evolutionary scenario based on the biological and chemical trends we can distinguish in them.

Coffee consumption attenuates short-term fructose-induced liver insulin resistance in healthy men.

BACKGROUND: Epidemiologic and experimental data have suggested that chlorogenic acid, which is a polyphenol contained in green coffee beans, prevents diet-induced hepatic steatosis and insulin resistance. OBJECTIVE: We assessed whether the consumption of chlorogenic acid-rich coffee attenuates the effects of short-term fructose overfeeding, dietary conditions known to increase intrahepatocellular lipids (IHCLs), and blood triglyceride concentrations and to decrease hepatic insulin sensitivity in healthy humans. DESIGN: Effects of 3 different coffees were assessed in 10 healthy volunteers in a randomized, controlled, crossover trial. IHCLs, hepatic glucose production (HGP) (by 6,6-d2 glucose dilution), and fasting lipid oxidation were measured after 14 d of consumption of caffeinated coffee high in chlorogenic acid (C-HCA), decaffeinated coffee high in chlorogenic acid, or decaffeinated coffee with regular amounts of chlorogenic acid (D-RCA); during the last 6 d of the study, the weight-maintenance diet of subjects was supplemented with 4 g fructose · kg(-1) · d(-1) (total energy intake ± SD: 143 ± 1% of weight-maintenance requirements). All participants were also studied without coffee supplementation, either with 4 g fructose · kg(-1) · d(-1) (high fructose only) or without high fructose (control). RESULTS: Compared with the control diet, the high-fructose diet significantly increased IHCLs by 102 ± 36% and HGP by 16 ± 3% and decreased fasting lipid oxidation by 100 ± 29% (all P < 0.05). All 3 coffees significantly decreased HGP. Fasting lipid oxidation increased with C-HCA and D-RCA (P < 0.05). None of the 3 coffees significantly altered IHCLs. CONCLUSIONS: Coffee consumption attenuates hepatic insulin resistance but not the increase of IHCLs induced by fructose overfeeding. This effect does not appear to be mediated by differences in the caffeine or chlorogenic acid content. This trial was registered at clinicaltrials.gov as NCT00827450.

Feeding strategies and energy to protein ratio on tambaqui performance and physiology

The objective of this work was to evaluate the effect of feed deprivation and refeeding with diets containing different energy to protein ratios (E/P) on the performance and physiology of juvenile tambaqui (Colossoma macropomum). A 4x2 factorial arrangement with three replicates was used, with four E/P ratios (11.5, 10.5, 9.5, and 8.5 kcal g-1 digestible energy per protein) and two feeding regimens (with and without deprivation), during 60 days. Fish from the food-deprived group were fasted for 14 days and refed from the fifteenth to the sixtieth day, whereas the remaining fish were fed for 60 days. At the end of the experimental period, weight of fish subjected to food deprivation was lower than that of those continuously fed; however, this condition did not influence the physiological parameters analyzed. Tambaqui fed 11.5 kcal g-1 achieved lower final weight than those fed with the other diets, in both regimens. Among the physiological parameters, only plasma protein presented significant increase in fish fed 8.5 kcal g-1, in both feeding regimens, probably due to the higher dietary protein concentration. These results indicate that fish show a partial compensatory growth, and that 10.5 kcal g-1 can be recommended for the diet of juvenile tambaqui.

Stable isotopes reveal trophic segregation by sex and age in the southern giant petrel in two different foodwebs

We investigated trophic ecology variation among colonies as well as sex- and age-related differences in the diet of the southern giant petrel Macronectes giganteus, a long-lived seabird that is sexually dimorphic in size. We measured stable isotopes (δ13C, δ15N) in blood samples collected during breeding at Bird Island (South Georgia, Antarctica) in 1998 and at 2 colonies in the Argentinean area of Patagonia in 2000 and 2001. Individuals from South Georgia showed lower δ13C and δ15N values than those in Patagonia, as expected from the more pelagic location and the short length of the Antarctic food web. Males and females showed significant differences in the isotopic signatures at both localities. These differences agree with the sexual differences in diet found in previous studies, which showed that both sexes rely mainly on penguin and seal carrion, but females also feed extensively on marine prey, such as fish, squid and crustaceans. However, males from Patagonia showed significantly higher δ15N and δ13C values than females did, and the reverse trend was observed at South Georgia. This opposite trend is probably related to the different trophic level of carrion between locations: whereas penguins and pinnipeds in Patagonia rely mainly on fish and cephalopods, in South Georgia they rely mainly on krill. Stable isotope values of male and female chicks in Patagonia did not differ; both attained high values, similar to adult males and higher than adult females, suggesting that parents do not provision their single offspring differently in relation to sex; however, they seem to provide offspring with a higher proportion of carrion, probably of higher quality, and more abundant food, than they consume themselves. Stable isotopes at South Georgia were not affected by age of adults. We have provided new information on intraspecific segregation in the diet in a seabird species and have also underlined the importance of considering food web structure when studying intraspecific variability in trophic ecology.

Ontogenetic dietary changes in male South American fur seals Arctocephalus australis in northern and central Patagonia, Argentina.

This study assessed ontogenetic dietary changes in male South American fur seals Arctocephalus australis in northern and central Patagonia (Argentina) using stable isotope ratios (δ15 N and δ13 C) in vibrissae and bones. Sucking pups were characterised by higher δ15 N values and lower δ13 C values than older specimens. Weaning was associated with a marked drop of δ15 N values, both in bone and vibrissae. Such a drop was inconsistent with the consumption of local prey and may reveal movement to distant foraging grounds or physiological changes associated with either fasting or rapid growth. Stable isotope ratios indicated that juveniles fed more pelagically than subadults and adults, but that there were no major differences between the 2 latter age categories. As subadults and adults are rather similar in body mass and are much larger than juveniles, body mass may play a role in the ontogenetic dietary changes reported. Nevertheless, demersal benthic prey were always scarce in the diet of male fur seals, which relied primarily on Argentine shortfin squid and small pelagic fish throughout life, though adults also consumed large amounts of decapod crustaceans available at shallow depths. Vibrissae did not reveal regular oscillations of δ15 N or δ13 C, except in 1 individual. Thus, male fur seals from northern and central Patagonia do not appear to migrate regularly between isotopically distinct areas, although nomadic displacements cannot be ruled out.

ARSÊNIO E ARROZ: TOXICIDADE, METABOLISMO E SEGURANÇA ALIMENTAR

Arsenic is considered a semimetal, and its wide distribution in the Earth's crust in different chemical forms, including organic and inorganic species, has a great deal of influence on the mechanisms of toxicity. Exposure to arsenic can be either through occupational practice (use of pesticides) or by the consumption of water and food containing the element. Rice is considered a fundamental constituent of the basic diet of Brazilians and is usually cultivated in flooded conditions. Such a plantation system results in an increased amount of As in the soil and hence a greater accumulation of As in the plant, which is highlighted by the inorganic species' classification as highly toxic. Besides the use of mitigation techniques to reduce the toxicological risk, monitoring the concentration of As and its chemical species in rice and rice products is required through the establishment of legislation in the area. Thus, some world organizations are conducting improved research to determine and establish acceptable concentrations of As and its chemical species in rice, e. g., in 2012, FDA researchers described a chemical speciation methodology for As in rice and rice products. Hence, the application of existing chemical speciation methods and the establishment of parameters for ensuring food security and exposure risk assessment deserve particular consideration.

Carbohydrate intake in children - associations with dietary intakes, growth, serum lipids,and dental health. The STRIP Project

This study is part of the STRIP study, which is a long-term, randomized controlled trial, designed to decrease the exposure of children in the intervention group (n=540) to known risk factors of atherosclerosis. The main focus of the intervention was the quality of dietary fat. The control group (n=522) did not receive any individualized counselling. Food consumption was evaluated with food records, and blood samples were drawn and growth was measured regularly for all participating children from 13 months to 9 years. A subsample of 66 children participated in a dental health survey. The number of studies on children’s carbohydrate intake, especially fibre intake, is insufficient. The current international recommendations for fibre intake in children are based on average assumptions and data extrapolated from intakes in adults and intake recommendations for adults. Finnish nutrition recommendations lack strict recommendations for dietary fibre in children. Due to fibre’s high bulk volume, excessive dietary fibre is considered to decrease energy density and hence it may have an adverse effect on growth. If fats are reduced from the diet, the low-fat diet may become high in sucrose. Therefore, especially in the STRIP study, it is important to determine the use of fibre and sucrose in children and possible associations with growth and nutrition as well as dental health. The results of the present study indicate that a high fibre intake does not displace energy or disturb growth in children and that children with high fibre intake have better quality of diet than those with low fibre intake. Additionally, dietary fibre intake associated inversely with serum cholesterol concentration. Other carbohydrates also affected serum lipid levels as well, since total carbohydrates, sucrose, and fructose increased serum triglyceride concentration. Total carbohydrate intake reduced HDL cholesterol concentration only in children with apoE3 or apoE4 phenotype. Over the period from the 1970s to the 1990s the dental health of children in Finland has substantially improved despite an increase in sucrose intake. The improvement was thought to be due to improved dental hygiene and the use of fluorine. However, during the past twenty years improvement in dental health has stopped. The present study showed that high long-term sugar intake increases risk of caries in children. High intake of sugar had also negative effects on the diet of children, because it worsens dietary quality by displacing essential nutrients. Furthermore, the quality of dietary fat was worse in children with high sucrose intake. In this study the children’s high sucrose intake was not associated with overweight, but interestingly, it associated inversely with growth.

Disponibilidade de frutos e a dieta de Lycalopex vetulus (Carnivora - Canidae) em um cerrado de Mato Grosso, Brasil

A frutificação de 41 espécies consideradas como alimentos potenciais para mamíferos foi acompanhada mensalmente durante os anos de 1985 e 1986 e comparada com a dieta frugívora da raposa-do-campo (Lycalopex vetulus) em uma área de cerrado próxima ao Parque Nacional de Chapada dos Guimarães. O padrão de frutificação foi sazonal, com maior disponibilidade de frutos no começo da estação seca e começo da estação chuvosa. Hancornia speciosa, Rauwolfia sp. e Solanum lycocarpum apresentaram um padrão longo (nove a 12 meses) de frutificação, enquanto Guettarda viburnioides e Mouriri elliptica, um padrão curto (cinco a oito meses). Setenta por cento das espécies com frutos listados como alimentos potenciais foram consumidos por L. vetulus. Apesar do grande número de espécies utilizadas, um percentual pequeno (26%) de frutos foi consumido com freqüência acima de 10%. O consumo de frutos pela raposa foi oportunístico, em geral coincidindo com o padrão de frutificação na área de estudo. H. speciosa e S. lycocarpum foram consideradas espécies importantes na dieta de L. vetulus, desde que proporcionaram fontes alimentares disponíveis ao longo do ano, inclusive em períodos de baixa disponibilidade como durante o pico da estação seca. Alterações na freqüência de consumo de certas espécies de frutos, como a substituição de uma espécie de fruto por outra, parecem refletir estados de saciação da raposa-do-campo e interesse por novos frutos atrativos. Aparentemente, acessibilidade, forte odor e conteúdo energético são características dos frutos que determinam preferências primárias da raposa-do-campo por determinadas espécies. Devido ao grande número de diferentes tipos de frutos consumidos e à elevada freqüência de sementes intactas nas fezes durante diferentes períodos do ano, L. vetulus pode ser considerado um dispersor potencial na área de estudo.
