Blood plasma lipidomic signature of epicardial fat in healthy obese women.

OBJECTIVES: A lipidomic approach was employed in a clinically well-defined cohort of healthy obese women to explore blood lipidome phenotype ascribed to body fat deposition, with emphasis on epicardial adipose tissue (EAT). METHODS: The present investigation delivered a lipidomics signature of epicardial adiposity under healthy clinical conditions using a cohort of 40 obese females (age: 25-45 years, BMI: 28-40 kg/m(2) ) not showing any metabolic disease traits. Lipidomics analysis of blood plasma was employed in combination with in vivo quantitation of mediastinal fat depots by computerized tomography. RESULTS: All cardiac fat depots correlated to indicators of hepatic dysfunctions (ALAT and ASAT), which describe physiological connections between hepatic and cardiac steatosis. Plasma lipidomics encompassed overall levels of lipid classes, fatty acid profiles, and individual lipid species. EAT and visceral fat associated with diacylglycerols (DAG), triglycerides, and distinct phospholipid and sphingolipid species. A pattern of DAG and phosphoglycerols was specific to EAT. CONCLUSIONS: Human blood plasma lipidomics appears to be a promising clinical and potentially diagnostic readout for patient stratification and monitoring. Association of blood lipidomics signature to regio-specific mediastinal and visceral adiposity under healthy clinical conditions may help provide more biological insights into obese patient stratification for cardiovascular disease risks.

Identificació de marcadors biològics amb potencial per a l’optimització sensorial i tecnològica de la carn de porc i pernil curat

L’aplicació de tecnologies innovadores per a l’anàlisi de la qualitat (proteòmica) i per al processat de productes carnis (envasament actiu i altes pressions hidrostàtiques) amb la finalitat d’optimitzar la qualitat i la seguretat de productes carnis llestos per al consum fou evaluat. Els resultats obtinguts amb l’anàlisi proteòmic van permetre la detecció de pèptids/ proteïnes candidats a marcadors proteics de la qualitat dels lloms i dels pernils. La detecció d’aquests marcadors a la matèria primera (llom i pernil fresc) ajudaria a predir la qualitat final dels productes carnis processats (llom cuit i pernil curat), i proporcionaria una eina per al control de la qualitat de la carn de porc. No obstant, la validació del paper d’aquestes proteïnes a la qualitat final dels productes carnis és necessària abans de poder-los considerar marcadors proteics. Per altra banda, es va estudiar la possiblitat de millorar la seguretat alimentària de llonganissa sense sal afegida obtinguda amb el procés QDS® process a través l’ús de tecnologies innovadores (envasament actiu i altes pressions hidrostàtiques). La llonganissa sense sal afegida no va permetre el creixement de L. monocytogenes. No obstant, el patogen seria capaç de sobreviure durant la vida útil del producte en cas de recontaminació. L’envasament antimicrobià amb la inclusió de nisina com a antimicrobià natural es pot considerar un mètode efectiu per a millorar la seguretat de la llonganissa estudiada. L. monocytogenes va sobreviure al tractament d’alta pressió hidrostàtica (600 MPa, 5 min, 12ºC) gràcies a les característiques del producte de baixa activitat d’aigua i presència de lactat a la seva formulació. Per aquest motiu, la APH no es consideraria un tractament apropiat per a reduir la presència de L. monocytogenes en aquest tipus de producte.

The occurrence of reptiles in Barn Owl diet in Europe

Capsule We present a review of the propensity to eat reptiles in the Barn Owl Tyto alba in Europe. Based on the analysis of 591 published studies reporting 3.07 million prey items identified in pellets, only 2402 reptiles (0.08%) were found. Reptiles were most often captured in southern parts of the European continent and on islands. A large proportion of the 1304 identified reptiles to the species level were nocturnal Gekkonidae (77.1%).

Rice Consumption in the United States: New Evidence from Food Consumption Surveys, July 2005

Evidence from recent U.S. food consumption surveys provides new information on the distribution of rice consumption, the characteristics of rice consumers, and the diets of people who consume rice. Recently available data from nationally representative surveys of food consumed by individuals in the United States allowed comparison of consumption today (2001-02) with consumption in the mid-1990s. Data come from the Continuing Survey of Food Intakes by Individuals (1994-96) and the National Health and Nutrition Examination Survey (2001-02). Rice is consumed by a significant portion of the U.S. adult population. In 2001-02, over 18 percent (18.2 percent) of adults reported eating at least half a serving of white or brown rice in one day of observed intake. This share was slightly higher than that of 1994-96 (17.4 percent). Compared with others, individuals who consumed at least half a serving of white or brown rice in the observed day of intake consumed a smaller share of calories per day from fat and saturated fat; less discretionary fat or added sugar; and more fiber, dietary folate, fruit, vegetables, and enriched grains. Consumers eating rice were more likely to eat a diet that included choices of foods consistent with the 2005 U.S. Dietary Guidelines.

Réduction de la consommation de sel: opportunité, impact et stratégies. [Population reduction of salt consumption: opportunities, impact and strategies].

A national survey showed that Swiss people eat high quantity of salt (9.1 g per day on average). The Swiss Federal Office of Public Health (FOPH) has launched a strategy to reduce salt intake in the population in order to decrease cardiovascular morbidity and mortality, mainly via blood pressure reduction. The most effective public health measures are to reduce the salt content of processed food rich in salt because they do not need to change consumers' eating behaviours. The FOPH has chosen to collaborate with the food industry on a voluntary basis. Regular population-based surveys will be needed to monitor the impact of current measures on salt consumption, hypertension prevalence as well as cardiovascular morbidity and mortality in the years to come.

Odontopus brevirostris (Hustache, 1936) (Coleoptera, Curculionidae) associated with new host plants belonging to Annona (Annonaceae)

Odontopus brevirostris (Hustache, 1936) feeding on Annona squamosa L., A. cherimola Mill., A. glabra L., and A. muricata L. was observed. The last three host plants are recorded for the first time. The endophitic oviposition occurs in the veins of the ventral surface of the young leaves. The larvae, leaf miners, eat the parenchyma and the adults make small holes in the leaves. The pupation occurs in spherical cocoons protected by a sort of nest (pupation chamber) between the two epidermal layers.

Impact of physical activity on energy balance, food intake and choice in normal weight and obese children in the setting of acute social stress: a randomized controlled trial.

BACKGROUND: Psychological stress negatively influences food intake and food choices, thereby contributing to the development of childhood obesity. Physical activity can also moderate eating behavior and influence calorie intake. However, it is unknown if acute physical activity influences food intake and overall energy balance after acute stress exposure in children. We therefore investigated the impact of acute physical activity on overall energy balance (food intake minus energy expenditure), food intake, and choice in the setting of acute social stress in normal weight (NW) and overweight/obese (OW/OB) children as well as the impact of psychological risk factors. METHOD: After receiving written consent from their parents, 26 NW (BMI < 90(th) percentile) and 24 7-to 11-year-old OW (n = 5)/OB (n = 19, BMI ≥ 90(th) percentile) children were randomly allocated using computer-generated numbers (1:1, after stratification for weight status) to acute moderate physical or to sedentary activity for 30 min. Afterwards, all children were exposed to an acute social stressor. Children and their parents completed self-report questionnaires. At the end of the stressor, children were allowed to eat freely from a range of 12 different foods (6 sweet/6 salty; each of low/high caloric density). Energy balance, food intake/choice and obesity-related psychological risk factors were assessed. RESULTS: Lower overall energy balance (p = 0.019) and a decreased choice of low density salty foods (p < 0.001) in NW children compared with OW/OB children was found after acute moderate physical activity but not sedentary activity. Independent of their allocation, OW/OB children ate more high density salty foods (104 kcal (34 to 173), p = 0.004) following stress. They scored higher on impulsive behavior (p = 0.005), restrained eating (p < 0.001) and parental corporal punishment (p = 0.03), but these psychological factors were not related to stress-induced food intake/choice. Positive parenting tended to be related to lower intake of sweet high density food (-132 kcal, -277 to 2, p = 0.054). CONCLUSIONS: In the setting of stress, acute moderate physical activity can address energy balance in children, a benefit which is especially pronounced in the OW/OB. Positive parenting may act as a protective factor preventing stress-induced eating of comfort food. TRIAL REGISTRATION: clinicaltrials.gov NCT01693926 The study was a pilot study of a project funded by the Swiss National Science Foundation (CRSII3_147673).

Food's visually perceived fat content affects discrimination speed in an orthogonal spatial task.

Choosing what to eat is a complex activity for humans. Determining a food's pleasantness requires us to combine information about what is available at a given time with knowledge of the food's palatability, texture, fat content, and other nutritional information. It has been suggested that humans may have an implicit knowledge of a food's fat content based on its appearance; Toepel et al. (Neuroimage 44:967-974, 2009) reported visual-evoked potential modulations after participants viewed images of high-energy, high-fat food (HF), as compared to viewing low-fat food (LF). In the present study, we investigated whether there are any immediate behavioural consequences of these modulations for human performance. HF, LF, or non-food (NF) images were used to exogenously direct participants' attention to either the left or the right. Next, participants made speeded elevation discrimination responses (up vs. down) to visual targets presented either above or below the midline (and at one of three stimulus onset asynchronies: 150, 300, or 450 ms). Participants responded significantly more rapidly following the presentation of a HF image than following the presentation of either LF or NF images, despite the fact that the identity of the images was entirely task-irrelevant. Similar results were found when comparing response speeds following images of high-carbohydrate (HC) food items to low-carbohydrate (LC) food items. These results support the view that people rapidly process (i.e. within a few hundred milliseconds) the fat/carbohydrate/energy value or, perhaps more generally, the pleasantness of food. Potentially as a result of HF/HC food items being more pleasant and thus having a higher incentive value, it seems as though seeing these foods results in a response readiness, or an overall alerting effect, in the human brain.

A Bowl of Strawberries Can Go A Long WAY..., 2009

Strawberries are one of the healthiest fruits you can eat. They are a great source of Vitamin C. One serving of just eight strawberries will provide 140 % of the US Recommended Daily Allowance of Vitamin C. In a recent study, strawberries ranked second among the top ten fruits in antioxidant capacity (TAC), which is one reason why they may help prevent cancer and heart disease.

Qualitat microbiològica dels productes vegetals frescos mínimament processats i desenvolupament de tecnologies de bioconservació mitjançant bacteris de l'àcid làctic

Food safety today is conditiones by the implementation of new Tecnologies for food preservation based on mild treatments and mínimum process, Novel foods, severe restrictions in the toxicològic profile of chemical preservatives, And the drastic limitation /prohibition of antibiotics, and as a consequence, by the New emergint pathogens or by the increase of classical food-borne pathogens. Biopreservatives appear within this context with strong expectations, because thei are safe microorganisms of ten isolated from foods, chemical compounds of natural origin -antimicrobial peptides and proteins, botanical extracts, enzymes- and sintetic compounds based on natural structures, but less toxic and more eficients, like the amtimicrobial peptides. Among the microbial biopreservatives, lactic acid bacteria have shown great possibilities in the preservation of cured meat products, ready to eat fresh fruit and vegetables, as well as to decrease microbial spoilage in food by products before processing for valorization. Our laboratory has performed an extense survey of the microbiological quality of fresh fruit and vegetables, and of ready-to-eat products, and have detect low levels, but significant of Salmonella sp., E. coli and Listeria spp., including L.monocytogenes, in retail markets and Supermarkets of Catalonia. Due to this reason, we started a project consisting of Developing application of lactic acid bacteria (LAB) obtained from these products, as biopreservatives. LAB were abundant in ready-to-eat fresh fruits and vegetables, specially in germinated seeds. From these products we obtained strains of Leuconostoc, Lactobacillus and Weissella, producing bacteriocins and with a Significant activity of control of L.monocytogenes in fresh apple and cut salad. Ather strains were efective in the inhibition of fungal rot during postharvest caused by Penicillium expansum

The Visual Dysphagia Questionnaire: Evaluating the first Tool for Assessing Food Consistency-Dependent Dysphagia in Eosinophilic Esophagitis

Background and Aims: The international EEsAI study group iscurrently developing the first a ctivity index specific forEosinophilic Esophagitis (EoE). None of the existing dysphagiaquestionnaires take into account the consistency of theingested food t hat considerably impacts the symptompresentation. Goal: To d evelop and evaluate an E oE-specificquestionnaire assessing dysphagia caused by foods of differentconsistencies.Methods: B ased on patient interviews and chart reviews, a nexpert panel ( EEsAI study g roup) identified internationallystandardizedfood prototypes t ypically a ssociated with EoErelateddysphagia. Food consistencies were c orrelated withEoE-related d ysphagia, t aking into account p otential f oodavoidance and f ood processing. This V isual D ysphagiaQuestionnaire (VDQ) was piloted in 20 patients and is currentlyevaluated in a cohort of 150 adult EoE patients.Results: T he following 8 food c onsistency prototypes w ereidentified: soft foods (pudding, jelly), grits, toast bread, Frenchfries, dry rice, ground meat, raw fibrous f oods (eg. apple,carrot), s olid m eat. Dysphagia was r anked o n a 4-point Likertscale (0=no difficulties; 3= severe difficulties, food will not pass).First analysis demonstrated that severity of dysphagia is relatedto the eosinophil load and presence of esophageal strictures.Conclusions: T he VDQ i s the first EoE-specific tool f orassessing dysphagia caused by i nternationally-standardizedfoods of different consistencies. This instrument also addressesfood avoidance behaviour and food processing habits. This toolperformed well in a p ilot study a nd is currently evaluated in acohort of 150 adult EoE patients.

Amphibians in the diet of European Barn Owls

We present a review of the propensity to eat amphibians in the Barn Owl Tyto alba in Europe. Based on the analysis of 596 published studies reporting 3.32 million prey items identified in pellets, 17 869 amphibians (0.54%) were found. An analysis of 9036 amphibians identified to the species level showed that Barn Owls avoid consuming toxic species, and they are able to capture tree frogs (Hylidae) only rarely. The true frogs (Ranidae) are by far the most frequently captured amphibians followed by spadefoot toads (Pelobatidae) and Parsley frogs (Pelodytidae).

Who eats healthily? A population-based study among young Swiss residents.

OBJECTIVE: To assess whether Swiss residents aged 15-24 years follow current nutritional guidelines and whether differences exist according to gender and weight status. DESIGN: Cross-sectional national survey. SETTING: Switzerland. SUBJECTS: The 1786 participants (48·4 % women) were divided into overweight, normal weight and underweight. We used traditional BMI cut-offs for people ≥18 years of age (underweight = BMI < 18·5 kg/m2, normal weight = BMI ≥ 18·5 kg/m2 and <25 kg/m2, overweight = BMI ≥ 25 kg/m2) and age- and gender-appropriate tables for people aged <18 years, with BMI calculated from self-reported weight and height. We performed bivariate analyses by gender, and then bivariate and multivariate analyses comparing overweight to normal weight people (excluding underweight, n 129, 71·6 % women) regarding adherence to recommendations for fruit, vegetables, meat, fish and dairy products; physical activity; attitude towards body weight; depression, smoking and alcohol consumption. RESULTS: Overall, adherence to nutritional guidelines was low, particularly for vegetables and dairy products. Women had a higher adherence than men except for fish and dairy products. In the multivariate analyses, overweight women had a lower vegetable intake, were less satisfied with body weight and had more often been on a diet, whereas overweight men were less satisfied with body weight and wanted to lose weight more often than their normal weight peers. There were no significant differences for physical activity. CONCLUSIONS: Overweight prevention programmes should target youth specifically by gender and promote an appropriate self-perception. Overweight women should be encouraged to eat more vegetables and men to be more sensitised on healthy food. Further research is needed to assess how to make nutritional guidelines more adaptable to young people's daily life.

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.
