Recent Advances in Biotechnological Methods for Wheat Gluten Immunotoxicity Abolishment – a Review
2021
Due to the increasing incidence of gluten intolerance, researchers are focusing on finding ways to eliminate immunotoxicity of wheat, this would allow the use of wheat products for gluten-intolerant consumers. The article reviews recent studies on biotechnological methods to eliminate and reduce the immunogenicity of wheat products. So far, many gluten removal methods have been proposed, but their efficacy levels were quite different. Enzymatic treatment of gluten fragments can be considered the simplest and non-invasive tool to eliminate the toxicity of gliadins and glutenins. For this purpose, various endogenous enzymes derived from cereals, and also those of bacterial, fungal, plant, and…
“Five Keys to Safer Food” and COVID-19
2021
On 11 March 2020, coronavirus disease 2019 (COVID-19) was declared a pandemic by the World Health Organization (WHO) and, up to 18:37 a.m. on 9 December 2021, it has produced 268,440,530 cases and 5,299,511 deaths. This disease, in some patients, included pneumonia and shortness of breath, being transmitted through droplets and aerosols. To date, there is no scientific literature to justify transmission directly from foods. In this review, we applied the precautionary principle for the home and the food industry using the known “Five Keys to Safer Food” manual developed by the World Health Organization (WHO) and extended punctually in its core information from five keys, in the light of new…
Bioavailability of plant sterol-enriched milk-based fruit beverages: In vivo and in vitro studies
2015
Abstract This study for the first time compares the in vivo (response in serum from individuals of an interventional study) and in vitro effects (bioaccessibility determined from simulated gastrointestinal digestion) of two plant sterol (PS)-enriched milk-based fruit beverages (with and without tangerine fruit juice rich in β-cryptoxanthin (β-Cx)) in order to assess their suitability as PS-enriched food matrixes, and the possible interactions between the two bioactive compounds (β-Cx and PS) that might affect their absorption. The randomized, double-blind, crossover study (performed in 36 postmenopausal women) showed the β-sitosterol and campesterol serum concentrations after four weeks of …
La influencia de la nutrición en la industria alimentaria
2021
Spanish Journal of Human Nutrition and Dietetics editors Conflicts of Interest declaration 2020-2022
2020
Se reconoce como Conflicto de Interés (COI), al conjunto de condiciones en las que el juicio profesional en relación a un interés primario, tiende a ser indebidamente influenciado por un interés secundario (como por ejemplo el beneficio económico)1 . Esta situación no es ajena a los procesos editoriales de revistas científicas, estando presente desde la producción de manuscritos por los/as autores/as, la revisión por pares y las gestiones de los/as miembros de los equipos editoriales.
Editorial decisions: highlighting the role of systematic reviews
2018
En 2014, el doctor Gerard Urrútia del Centro Cochrane Iberoamericano - Institut d'Investigació Biomèdica Sant Pau, escribió unas líneas editoriales para la Revista Española de Nutrición Humana y Dietética1 en las que ponía en valor la necesidad de "incrementar el rigor científico tanto en la producción de estudios científicos, que proporcionen las bases para una toma de decisiones bien fundamentada, como en su divulgación mediante publicaciones científicas de calidad" en el ámbito de la nutrición y la dietética. Asimismo vaticinaba que "cabría esperar, por una parte, un creciente interés en la producción de revisiones sistemáticas por parte de profesionales de nuestro medio, también entre d…

Biosorption of green and black tea polyphenols into Saccharomyces cerevisiae improves their bioaccessibility
2015
Infusions of green tea (GT) and black tea (BT) and the use of Saccharomyces cerevisiae as a natural matrix were employed to check the impact of biosorption on the possible fate of tea polyphenols in the gastrointestinal tract in terms of bioaccessibility and total antioxidant capacity (TEAC and ORAC assays). The maximum biosorption yields obtained were 47.61 ± 11.57 and 99.68 ± 5.25 mg/g from GT and BT infusions, respectively. A significant increase (p < 0.05) in the recovery of phenolic compounds was shown after in vitro digestion. The bioaccessible fractions generally exhibited higher antioxidant capacities in both tea infusions and suspensions of S. cerevisiae versus non-digested samples…
Modulation of biotransformation and elimination systems by BM-21, an aqueous ethanolic extract from Thalassia testudinum, and thalassiolin B on human…
2012
Abstract BM-21 is an extract obtained from Thalassia testudinum marine plant with pharmacological properties. The effects of BM-21 and thalassiolin B (TB), its main component, on enzyme and transport proteins involved in drug metabolism and excretion in human cultured hepatocytes were evaluated. Cells were exposed for 48 h to sub-cytotoxic concentrations of BM-21 or TB. Effects on P450 isoforms revealed significant reductions of CYP1A2, 3A4 and 2D6 activities (up to 56%, 66% and 44% inhibition, respectively) after exposition to BM-21, no changes on CYP2A6 and 2C9 activities. TB produced a concentration-dependent reduction of all P450 activities. In addition, a decrease in total UGT and UGT2…
