La definición de fibra dietética – discusiones sostenidas durante el Noveno Simposio de Fibra Vahouny: Llegando a un acuerdo científico.
Journal Article 2010
La Comisión de Codex Alimentarius, adoptó una definición para la fibra dietética en Junio del 2009, basada en la recomendación del Comité Codex en Nutrición y Alimentos para Regímenes Especiales (CCNFSDU por sus siglas en inglés) para su aprobación en Noviembre del 2008. La definición enumera tres categorías de polímeros de hidratos de carbono que no son hidrolizados por las enzimas endógenas en el intestino delgado de humanos. Sin embargo, la definición dejó la inclusión de hidratos de carbono con grados de polimerización (GP) en el rango de 3 a 9 a discreción de las autoridades nacionales y dejó pendiente por definir los “efectos fisiológicos beneficiosos para la salud”. Los comités de ILSI Europa e ILSI Norte América especializados en hidratos de carbono dietéticos organizaron un foro en el Noveno Simposio Vahouny de Fibra en el 2010 con el fin de discutir la forma en la cual se puedan resolver estos asuntos de instrumentación para llegar a un consenso científico. Los resultados de esta sesión son alentadores e indicaron que la comunidad científica concuerda en mantener un consenso mundial respecto a la inclusión de hidratos de carbono no digeribles con >GP3 como fibra dietética y en una lista central y no exhaustiva, los efectos fisiológicos benéficos que tienen las fibras dietéticas. Estos resultados son congruentes con los acuerdos mundiales previos.
Persistence of Human Noroviruses on Food Preparation Surfaces and Human Hands
Journal Article 2010
This study, published in Food and Environmental Virology (2009;1:141–147), examines the persistence of representative human noroviruses on the fingertips of volunteers and on commonly used food preparation surfaces.
Selection and Characterization of DNA Aptamers With Binding Selectivity to Campylobacter jejuni Using Whole-Cell SELEX
Journal Article 2010
To identify DNA aptamers demonstrating binding specificity to Campylobacter jejuni cells, a whole-cell Systemic Evolution of Ligands by EXponential enrichment (SELEX) method was applied to a combinatorial library of FAM-labeled single-stranded DNA molecules. This study was published in Applied Microbiology and Biotechnology (2010;87:2323–2334).
The Definition of Dietary Fiber - Discussions at the Ninth Vahouny Fiber Symposium - Building Scientific Agreement
Journal Article 2010
This article, published in Food and Nutrition Research (2010;54), discusses that the scientific community agrees on maintaining a worldwide consensus regarding the inclusion of non-digestible carbohydrates with ≥DP3 as dietary fiber and on a core, non-exhaustive list of beneficial physiological effects that dietary fibers have.
The Tricks Learnt by Human Enteric Pathogens From Phytopathogens to Persist within the Plant Environment.
Journal Article 2010
Through recent advances in our understanding of microbial/plant interactions it is becoming apparent that human pathogens, principally, Escherichia coli O157:H7 and Salmonella are adapted to survive in the plant environment. The aforementioned pathogens have surface epitopes that can bind to plant structures such as stomata to aid attachment. This work was published in Current Opinions in Biotechnology (2010;21:131–136).
Threshold Dose for Peanut: Risk Characterization Based Upon Diagnostic Oral Challenge of a Series of 286 Peanut-Allergic Individuals
Journal Article 2010
Clinical records of 286 consecutive patients reacting positively with objective symptoms to double-blind, placebo-controlled oral peanut challenges at University Hospital, Nancy, France were examined for individual no observed adverse effect levels (NOAELs) and lowest observed adverse effect levels (LOAELs). This study was published in Food and Chemical Toxicology (2010;48:814–819).
Critical Research Needs in Food Safety Microbiology
Journal Article 2009
As discussed in this review published in the December issue of Food Protection Trends, control, detection, and mitigation were identified as three critically important research areas by the ILSI North America Committee on Food Microbiology for looking at spore-forming bacterial pathogens, spoilage organisms, and Salmonella.
Early Risk Determinants and Later Health Outcomes
Journal Article 2009
This workshop, discussed in the American Journal of Clinical Nutrition (2009;89), stemmed from a quest to consolidate current knowledge on the early determinants of maternal and child health outcomes related to obesity, cardiovascular disease risk, and neurodevelopment. The primary goal was to delineate the relative influence of genetics and environmental factors.
Functional Foods for Health Promotion: Microbes and Health
Journal Article 2009
This set of expanded abstracts, published in Nutrition Reviews (2009;67:40–48), includes a general introduction and overview of how diet or dietary components can influence microbial growth and, ultimately, disease risk and overall health.
Functional Foods for Health Promotion: State-of-the-Science on Dietary Flavonoids
Journal Article 2009
This article, published in Nutrition Reviews (2009;67:736–743), indicates that dietary flavonoids, particularly flavanols, show promising potential for reducing cardiovascular disease risk via reduction of inflammation and improvement in vascular function.
