Título: | In vitro evaluation of dietary compounds to reduce mercury bioavailability |
Autor: | Jadán Piedra, Carlos; Vélez, Dinoraz CSIC ORCID; Devesa, Vicenta CSIC ORCID | Palabras clave: | Mercury Food Swordfish Bioavailability Dietary strategies |
Fecha de publicación: | 6-dic-2017 | Editor: | Elsevier | Citación: | Food Chemistry 258: 353-359 (2018) | Resumen: | Mercury in foods, in inorganic form [Hg(II)] or as methylmercury (CH3Hg), can have adverse effects. Its elimination from foods is not technologically viable. To reduce human exposure, possible alternatives might be based on reducing its intestinal absorption. This study evaluates the ability of 23 dietary components to reduce the amount of mercury that is absorbed and reaches the bloodstream (bioavailability). We determined their effect on uptake of mercury in Caco-2 cells, a model of intestinal epithelium, exposed to Hg(II) and CH3Hg standards and to swordfish bioaccessible fractions. Cysteine, homocysteine, glutathione, quercetin, albumin and tannic reduce bioavailability of both mercury species. Fe(II), lipoic acid, pectin, epigallocatechin and thiamine are also effective for Hg(II). Some of these strategies also reduce Hg bioavailability in swordfish (glutathione, cysteine, homocysteine). Moreover, extracts and supplements rich in these compounds are also effective. This knowledge may help to define dietary strategies to reduce in vivo mercury bioavailability. | Versión del editor: | https://doi.org/10.1016/j.foodchem.2017.12.012 | URI: | http://hdl.handle.net/10261/162822 | DOI: | 10.1016/j.foodchem.2017.12.012 | ISSN: | 0308-8146 |
