Physics of agarose fluid gels: Rheological properties and microstructure

2021

Agarose, a strongly gelling polysaccharide, is a common ingredient used to optimize the viscoelastic properties of a multitude of food products. Through aggregation of double helices via hydrogen bonds while cooling under quiescent conditions it forms firm and brittle gels. However, this behavior can be altered by manipulating the processing conditions viz shear. For example, gelation under shear leads to microgel particles with large surface area, which in turn leads to completely different rheological properties and texture. Such fluid gels are shown to play an important role in texture modification of foods and beverages for dysphagia patients. In this study, different concentration of a…

Life-course perspectives of milk consumption among young Norwegian women and their knowledge of milk as a source of iodine: a qualitative study.

2021

Mild to moderate iodine deficiency has been found among young Norwegian women of reproductive age. In Norway, cow’s milk is the main source of iodine; however, milk consumption is decreasing, particularly among young women. This study aimed to investigate milk consumption practices in young Norwegian women and their attitudes toward milk consumption from childhood to young adulthood in a life-course perspective and their knowledge of milk as a source of iodine. Convenience sampling was used to recruit 30 bachelor students (women, 18–25 years old) from five different study programs. Interpretative phenomenological analysis (IPA) was used to interpret milk consumption practices from a life-co…

Reproducibility and relative validity of a newly developed web-based food-frequency questionnaire for assessment of preconception diet

2019

Abstract Background The importance of diet and nutrition during preconception age is a window of opportunity to promote future parental and transgenerational health. As a sub-study to a large Norwegian study, ‘Diet today – health of tomorrow’, a food-frequency questionnaire (FFQ) was developed to assess diet during the preconception phase in young adults aged 20 – 30 years and in this paper we report the reproducibility and relative validity of this questionnaire. Methods The FFQ was developed from an existing FFQ validated in adolescents. Participants were recruited on social media and at a university. Reproducibility was assessed by comparing the test and retest of the FFQ. Relative valid…

Evaluation of a short food frequency questionnaire used among Norwegian children.

2012

Objective: The aim of this study was to evaluate a short food frequency questionnaire (FFQ) against a four-day precoded food diary (PFD) with regard to frequency of food intake among Norwegian 9- and 13-year-olds. Subjects and design: A total of 733 9-year-olds and 904 13-year-olds completed first a short FFQ and one to two weeks later a four-day PFD. The short FFQ included questions about 23 food items, including different drinks, fruits, vegetables, bread, fish, pizza, sweets, chocolate and savoury snacks. The PFD covered the whole diet. Results: When comparing mean intake from the PFD with comparable food items in the FFQ, all food items showed that increasing intake measured with the PF…

¿Cómo deciden les jóvenes la transición a la educación postobligatoria? Diferencias entre centros públicos y privados-concertados

2017

Background of INCASI Project H2020-MSCA-RISE-2015 GA 691004. WP1: Compilation El objetivo del presente artículo es examinar el papel que juega la titularidad del centro en el que se cursa la educación secundaria obligatoria (ESO) en la decisión de transitar a la educación postobligatoria. En dicha encrucijada se contemplan también otras variables que se han constatado de gran peso en la toma de decisión como son las notas previas obtenidas, el nivel formativo familiar, el sexo, las expectativas y las aspiraciones, partiendo del modelo decisional de transiciones educativas[1] que contempla el modelo de Boudon sobre los efectos primarios y secundarios. Los resultados obtenidos son los derivad…

Folate deficiency as predisposing factor for childhood leukaemia: a review of the literature

2017

© The Author(s). 2017. Background: Folic acid and its derivates, known as folates, are chemoprotective micronutrients of great interest because of their essential role in the maintenance of health and genomic integrity. The supplementation of folic acid during pregnancy has long been known to reduce the risk of neural tube defects (NTDs) in the foetus. Folate metabolism can be altered by many factors, including adequate intake through diet. Folate deficiency can compromise the synthesis, repair and methylation of DNA, with deleterious consequences on genomic stability and gene expression. These processes are known to be altered in chronic diseases, including cancer and cardiovascular diseas…

Characterization and differentiation of rock varnish types from different environments by microanalytical techniques

2017

© 2017 Elsevier B.V. We investigated rock varnishes collected from several locations and environments worldwide by a broad range of microanalytical techniques. These techniques were selected to address the challenges posed by the chemical and structural complexity within the micrometer- to nanometer-sized structures in these geological materials. Femtosecond laser ablation-inductively coupled plasma-mass spectrometry (fs LA-ICP-MS), scanning transmission X-ray microscopy-near edge X-ray adsorption fine structure spectroscopy (STXM-NEXAFS) in combination with scanning electron microscopy (SEM) of focused ion beam (FIB) ultra-thin (100–200 nm) sections, conventional and polarization microscop…

Nutrition, physical activity, and other lifestyle factors in the prevention of cognitive decline and dementia

2021

Multiple factors combined are currently recognized as contributors to cognitive decline. The main independent risk factor for cognitive impairment and dementia is advanced age followed by other determinants such as genetic, socioeconomic, and environmental factors, including nutrition and physical activity. In the next decades, a rise in dementia cases is expected due largely to the aging of the world population. There are no hitherto effective pharmaceutical therapies to treat age-associated cognitive impairment and dementia, which underscores the crucial role of prevention. A relationship among diet, physical activity, and other lifestyle factors with cognitive function has been intensive…
