Análisis de la alimentación a partir del estudio isotópico de carbono y nitrógeno en sitios de la entidad arqueológica Goya-Malabrigo del Delta del R…
2018
En este capítulo se presentan nuevos datos isotópicos de restos óseos humanos y faunísticos provenientes de sitios arqueológicos de la entidad arqueológica Goya-Malabrigo localizados en el Delta del río Paraná. Estos estudios se realizaron en el marco de un convenio de cooperación con los laboratorios de isótopos de la University of Cape Town (Ciudad del Cabo, Sudáfrica). El objetivo del trabajo es ampliar los análisis isotópicos que se vienen desarrollando en el Delta del Paraná, con el fin de profundizar en el conocimiento de la dieta de los individuos que ocuparon el área bajo estudio en tiempos prehispánicos. Para cumplir con este objetivo se presentan los resultados de los estudios de …
La recuperació del Dietari sobre la Guerra de Successió d'Isidre Planes a la premsa periòdica valenciana (1912-1913)
2019
Entre el 1 de marzo de 1912 y el 31 de diciembre de 1913, el diario valenciano Las Provincias publicó, por entregas, la práctica totalidad del contenido del segundo volumen -correspondiente a los años 1708-1709- del conocido como Dietari de Isidre Planes, una obra monumental que abarca un período cronológico de catorce años (1705-1718) y que ha sido calificada como la crónica más completa y detallada de la Guerra de Sucesión en Valencia. Así, además de dar noticia de la misma, el presente estudio analiza las características de aquella edición periodística que vio la luz a inicios del siglo xx, y valora sus consecuencias y beneficios. Finalmente, también apunta el nombre de posibles responsa…
Fiesta pública y memorialística en la Barcelona barroca
2018
Una de les eines més efectives per poder conèixer amb més detall els esdeveniments de la història és la memorialística. Mitjançant l’estudi d’aquests testimonis de primera mà, ara som capaços d’esbrinar els interessos i les preocupacions del conjunt de la societat en cada període històric. Aquest article pretén descriure el funcionament general de la memorialística i les característiques dels dietaris més concretament. A través de l’estudi de dietaris institucionals catalans però també d’altres de caire privat, duts a terme per autors particulars, desgranem els detalls de la festa barroca de la ciutat comtal i entenem com els esdeveniments més rellevants afectaven la seua quotidianitat i la…
The intestinal 3M (microbiota, metabolism, metabolome) zeitgeist – from fundamentals to future challenges
2021
The role of the intestine in human health and disease has historically been neglected and was mostly attributed to digestive and absorptive functions. In the past two decades, however, discoveries related to human nutrition and intestinal host-microbe reciprocal interaction have established the essential role of intestinal health in the pathogenesis of chronic diseases and the overall wellbeing. That transfer of gut microbiota could be a means of disease phenotype transfer has revolutionized our understanding of chronic disease pathogenesis. This narrative review highlights the major concepts related to intestinal microbiota, metabolism, and metabolome (3M) that have facilitated our fundame…
Effect of fat nature and aroma compound hydrophobicity on flavor release from complex food emulsions.
2004
Complex food emulsions containing either hydrogenated palm kernel oil (vegetable fat) or anhydrous milk fat (animal fat) were flavored by using different aroma compounds. The fats differed by their fatty acid and triacylglycerol compositions and by their melting behavior, while the aroma compounds (ethyl butanoate, ethyl hexanoate, methyl hexanoate, mesifurane, linalool, diacetyl, cis-3-hexen-1-ol, and gamma-octalactone) differed by their hydrophobicity. Application of differential scanning calorimetry to fat samples in bulk and emulsified forms indicated differences in the ratio of solid-to-liquid between temperatures ranging from 10 to 35 degrees C. Solid-phase microextraction coupled wit…
Stabilization of a nutraceutical omega-3 fatty acid by encapsulation in ultrathin electrosprayed zein prolamine.
2010
Docosahexaenoic acid (DHA) is a long chain polyunsaturated fatty acid of the omega-3 series (omega-3), which exerts strong positive influences on human health. The target of this study was the stabilization by encapsulation of this bioactive ingredient in zein ultrathin capsules produced by electrospraying. The zein ultrathin DHA encapsulation was observed by ATR-FTIR spectroscopy to be more efficient against degradation under both ambient conditions and in a confined space (so-called headspace experiment). In the latter case, that more closely simulates a sealed food packaging situation, the bioactive DHA was considerably more stable. By fitting the degradation data to a specific auto-deco…
Deficiency of Vitamin C in Dairy Products and Supplementation in Milk by Adding the Bioactive Natural Products
2011
Since milk constitutes an important item in the human diet and since the importance of an adequate amount of vitamin C in the diet is becoming more fully appreciated, it appeared to us that any investigation that might yield further information as to how milks containing greater quantities of this dietary essential might be produced would be worth while. Sea buckthorn is a natural multi-vitamins and a major source of vitamin C, fruits containing vitamin C at a rate of two times more than rosehips and ten times more than citrus (200-1500 mg). Strengthening with Vitamin C will be considering of content of vitamin C in milk samples taken per season (winter, spring, summer, autumn). This contri…
Sleep-time physiological recovery is associated with eating habits in distressed working-age Finns with overweight: secondary analysis of a randomise…
2021
Background Association of physiological recovery with nutrition has scarcely been studied. We investigated whether physiological recovery during sleep relates to eating habits, i.e., eating behaviour and diet quality. Methods Cross-sectional baseline analysis of psychologically distressed adults with overweight (N = 252) participating in a lifestyle intervention study in three Finnish cities. Recovery measures were based on sleep-time heart rate variability (HRV) measured for 3 consecutive nights. Measures derived from HRV were 1) RMSSD (Root Mean Square of the Successive Differences) indicating the parasympathetic activation of the autonomic nervous system and 2) Stress Balance (SB) indica…
Development and evaluation of image-series for portion size estimation in dietary assessment among adults
2021
AbstractPortion size images are advantageous in dietary assessment. The aim of the present study was to develop and validate new culturally specific image-series for portion size estimation to be used in a new Norwegian version of a British web-based dietary assessment tool (myfood24). Twenty-three image-series of different foods, each containing seven portion size images, were created and validated in a group of adults (n41, 58 % female) aged 19–44 (median 23), out of which 63 % had higher (tertiary) education. The participants compared 46 portions of pre-weighed foods to the portion size images (1886 comparisons in total). Portion size estimations were either classified as correct, adjace…
Effects of maternal ageing and dietary antioxidant supplementation on ovulation, fertilisation and embryo development in vitro in the mouse.
1999
The present study aims to ascertain whether dietary supplementation with a mixture of vitamins C and E may prevent the maternal-age-associated decrease in both the number of ovulated oocytes after exogenous ovarian stimulation and embryo development in vitro in the mouse. Experimental females were fed a standard diet supplemented with i) high doses of vitamins C and E from the first day of weaning until 12 or 40 weeks of age; or ii) moderate doses of vitamins C and E from the first day of weaning until 12 weeks of age or from 22 to 33 weeks of age. The age-related reduction in ovulation rate was partially prevented by supplementing diet with high doses of vitamins C and E from the first day…
