Study of the factors influencing the bioaccessibility of 10 elements from chocolate drink powder
2016
Abstract A risk/benefit assessment of chocolate drink powder has been conducted by evaluating the total contents and the bioaccessibilities of Al, Ba, Cd, Cr, Cu, Fe, Mg, Mn, P and Zn. The bioaccessibility was studied considering the type of sample (traditional, light, diet and organic) and the different factors that may affect it, including physical-chemical parameters of the human digestive process (gastric pH, concentration of bile salts and presence of lipase) and the presence of dietary components (phytate, pectin, cellulose and tannin). The bioaccessibility varied greatly according to the sample type, being greater in the diet and organic samples, and on the element being considered (…
Lipid and fatty acid profile of the retina, RPE/choroid and lacrimal gland, and associations with dietary fatty acids in human subjects
2008
Purpose The contribution of dietary lipids to the accumulation of lipids in the retina during ageing and in the course of age related maculopathies remains under debate. Our objective was to establish associations between fatty acid profiles of ocular structures, and adipose tissue as a surrogate for the past dietary intake of the subjects. Methods Lipids and fatty acids were analyzed by tandem thin-layer chromatography-flame ionization detection and gas chromatography-flame ionization detection from the neural retina, RPE/choroid, lacrimal gland and adipose tissue, collected from 19 women and 8 men, aged 59–95 years. Results DHA concentrations in the neural retina were positively associate…

Työssäkäyvien vanhempien stressinhallintakeinojen ja vanhemmuustyytyväisyyden väliset yhteydet : onko vanhemmuuden stressin tasolla väliä?
2012
Tutkielmassa tarkasteltiin, onko stressinhallintakeinoilla (tilanteen muuttaminen, mukautuminen, uudelleenarviointi, oireiden vähentäminen ja välttely) yhteyttä vanhemmuustyytyväisyyteen ja onko yhteys samanlaista korkean ja matalan vanhemmuuden stressin tilanteessa. Tutkimuksessa tarkasteltiin myös, eroavatko paljon ja vähän vanhemmuuden stressiä kokevien käyttämät stressinhallintakeinot toisistaan sekä selvitettiin, millaisia stressinhallintakeinoja käyttävät paljon vanhemmuuden stressiä kokevat vanhemmat. Tutkimuksen aineisto on osa Jyväskylän yliopiston psykologian laitoksen tutkimus- ja kehittämishanketta ”Työn ja perheen yhteensovittamisen hallintastrategiat ja -keinot työhyvinvoinnin…
Feeding Dairy Ewes with Fresh or Dehydrated Sulla (Sulla coronarium L.) Forage. 1. Effects on Feed Utilization, Milk Production, and Oxidative Status
2022
Feeding dairy ewes with fresh sulla forage (FSF), a legume species containing condensed tannins (CT), has been shown to increase feed intake, milk yield, and casein and enhances the oxidative status of animals. Dehydration of FSF could be an alternative to hay-making to preserve the nutritional properties. This research aimed to compare the responses of dairy ewes fed with diets based on sulla hay (SH), pelleted dehydrated sulla forage (DSF), or FSF in terms of efficiency of feed utilization, milk production, and the balance between oxidant (reactive oxygen metabolites (ROMs)) and antioxidant (biological antioxidant potential (BAP)) substances at the plasma level. Ten first-lambing (FL) and…
Omega-3 Long-Chain Polyunsaturated Fatty Acids Intake in Children with Attention Deficit and Hyperactivity Disorder
2019
Omega-3 long-chain polyunsaturated fatty acids (LC-PUFA) play a central role in neuronal growth and in the development of the human brain, and a deficiency of these substances has been reported in children with attention deficit hyperactive disorder (ADHD). In this regard, supplementation with omega-3 polyunsaturated fatty acids is used as adjuvant therapy in ADHD. Seafood, particularly fish, and some types of nuts are the main dietary sources of such fatty acids in the Spanish diet. In order to assess the effect of the intake of common foods containing high amounts of omega-3 polyunsaturated fatty acids, a food frequency questionnaire was administered to parents of children with ADHD (N = …
Relationship between dysfunctional eating patterns and binge drinking in young people and associated risk factors
2022
La joventut (compresa entre els 18 i 30 anys) es considera un període de vulnerabilitat, en què és freqüent observar trastorns alimentaris, consum de drogues i una major tendència a buscar noves sensacions i comportaments de risc, entre moltes altres conductes. En concret, hi ha dos comportaments molt prevalents en els joves i s'associen amb conseqüències de salut molt negatives: el consum de menjar ultraprocessat i el consum d'alcohol. Tot i això, el problema no rau només en el tipus de consum (és a dir, beure alcohol o menjar menjar ràpid), sinó també en com es consumeix l'alcohol o el menjar. L'afartament es caracteritza per la ingesta de grans quantitats de menjar (afartament de menjar)…
Dietary exposure to mycotoxins through the consumption of commercial bread loaf in Valencia, Spain
2017
Abstract In this study, 80 commercial samples of bread loaves were purchased from different supermarkets located in Valencia (Spain). These samples were investigated for the presence of legislated and non-legislated mycotoxins. Results showed that samples were contaminated with Aflatoxins (AFs), Zearalenone (ZEA) and Enniatins (ENs) with a frequency of 20, 96, and 65% respectively. Aflatoxin B1 (AFB1), Aflatoxin B2 (AFB2) and Aflatoxin G1 (AFG1) were detected with concentrations ranged from 0.5 to 7.1 μg/kg. The samples contaminated with AFB1 showed values exceeding the maximum limit allowed in the EU. The sum of AFs also exceeded the maximum limit allowed in 6 samples. ENs contamination da…
The effects of an 8-year individualised lifestyle intervention on food consumption and nutrient intake from childhood to adolescence: the PANIC Study.
2021
Abstract We aimed to investigate the effects of a long-term, individualised, family-based lifestyle intervention on food consumption and nutrient intake from childhood to adolescence. We conducted an 8-year diet and physical activity intervention study in a population sample of children aged 7–9 years at baseline in 2007–2009. We allocated the participants to the intervention group (n 306) and the control group (n 198). We assessed diet by 4-d food records at baseline, 2-year follow-up and 8-year follow-up. We analysed the data using linear mixed-effects models adjusted for age at baseline and sex. The consumption of vegetables and vegetable oil-based spreads (fat ≥60 %) increased in the in…
Resilience to social defeat-induced increased in ethanol intake: neuroinflammation response
2022
El estrés social es el principal factor de riesgo de las conductas adictivas. El fenotipo susceptible al estrés se ha convertido en la última década en un objetivo de estudio para la aplicación de tratamientos eficaces que mejoren la resiliencia al estrés. La promoción del afrontamiento activo mediante intervenciones farmacológicas y ambientales positivas está científicamente validada en el tratamiento de las adicciones. Sin embargo, estas intervenciones para promover la resiliencia durante la adolescencia como medida preventiva de experiencias estresantes intensas durante la edad adulta no han sido ampliamente estudiadas. Por ello, el objetivo principal de la presente Tesis Doctoral fue de…
