Il contient autant ou plus de fer que cet autre aliment...\u201d Consommer un aliment en comparant deux sources diff\u00e9rentes d'un m\u00eame nutriment ne garantit pas que votre corps absorbe ce que vous pensez. Le concept est simple mais difficile \u00e0 mesurer : la biodisponibilit\u00e9. Il s'agit de la quantit\u00e9 de vitamines ou de min\u00e9raux disponibles dans un aliment donn\u00e9. Elle n'est pas seulement li\u00e9e \u00e0 la quantit\u00e9 contenue dans l'aliment lui-m\u00eame, mais aussi \u00e0 la quantit\u00e9 absorb\u00e9e et utilis\u00e9e par l'organisme. En d'autres termes, la biodisponibilit\u00e9 est le pourcentage d'un nutriment absorb\u00e9 par la muqueuse intestinale. Il est assez simple de d\u00e9terminer la quantit\u00e9 de nutriments que contient un aliment sp\u00e9cifique. En revanche, il est tr\u00e8s complexe de d\u00e9terminer la biodisponibilit\u00e9 de ces nutriments, car de nombreux facteurs entrent en jeu :<\/p>\n<ul>\n<li>Efficacit\u00e9 de la digestion et temps de transit digestif des aliments<\/li>\n<li>Autres consommations alimentaires pr\u00e9c\u00e9dant la prise d'un aliment donn\u00e9<\/li>\n<li>Composition nutritionnelle des autres aliments consomm\u00e9s simultan\u00e9ment<\/li>\n<li>Mode de pr\u00e9paration (cuit, cru, en pur\u00e9e)<\/li>\n<li>Source de la vitamine ou du nutriment en question (animale, v\u00e9g\u00e9tale, synth\u00e9tique)&nbsp;<\/li>\n<\/ul>\n<p>Par cons\u00e9quent, deux sources diff\u00e9rentes de fer n'auront pas la m\u00eame biodisponibilit\u00e9, par exemple les graines de chanvre par rapport \u00e0 un steak de b\u0153uf. De m\u00eame pour le calcium contenu dans le brocoli par rapport au calcium contenu dans les produits laitiers, le pourcentage d'absorption par l'intestin est totalement diff\u00e9rent. Afin de vous donner un exemple concret, voici un tableau d\u00e9crivant la biodisponibilit\u00e9 de diff\u00e9rentes sources de calcium :<\/p>\n<table border=\"1\" cellpadding=\"1\" cellspacing=\"1\" style=\"margin-top: 16px; margin-bottom: 16px; color: rgb(70, 70, 70); font-family: Arial, Helvetica, 'Nimbus Sans L', sans-serif; font-size: 11px; line-height: 16px; width: 668.888916015625px;\">\n<tbody style=\"border-top-style: none;\">\n<tr>\n<td class=\"rtecenter\" style=\"text-align: center;\">Cat\u00e9gories de<\/td>\n<td class=\"rtecenter\" style=\"text-align: center;\">Portion<\/td>\n<td class=\"rtecenter\" style=\"text-align: center;\">Teneur moyenne en calcium (mg)<\/td>\n<td class=\"rtecenter\" style=\"text-align: center;\">Pourcentage absorb\u00e9 par l'organisme<br \/>(%)<\/td>\n<\/tr>\n<tr>\n<td class=\"rtecenter\" style=\"text-align: center;\">Lait ou yaourt, entier, 2 %, 1 %, \u00e9cr\u00e9m\u00e9<\/td>\n<td class=\"rtecenter\" style=\"text-align: center;\">250 ml (1 c)<\/td>\n<td class=\"rtecenter\" style=\"text-align: center;\">300<\/td>\n<td class=\"rtecenter\" style=\"text-align: center;\">32.1<\/td>\n<\/tr>\n<tr>\n<td class=\"rtecenter\" style=\"text-align: center;\">Fromage cheddar&nbsp;<\/td>\n<td class=\"rtecenter\" style=\"text-align: center;\">42 g<\/td>\n<td class=\"rtecenter\" style=\"text-align: center;\">303<\/td>\n<td class=\"rtecenter\" style=\"text-align: center;\">32.1<\/td>\n<\/tr>\n<tr>\n<td class=\"rtecenter\" style=\"text-align: center;\">Brocoli<\/td>\n<td class=\"rtecenter\" style=\"text-align: center;\">125 ml (1\/2 c)<\/td>\n<td class=\"rtecenter\" style=\"text-align: center;\">35<\/td>\n<td class=\"rtecenter\" style=\"text-align: center;\">61<\/td>\n<\/tr>\n<tr>\n<td class=\"rtecenter\" style=\"text-align: center;\">\u00c9pinards<\/td>\n<td class=\"rtecenter\" style=\"text-align: center;\">125 ml (1\/2 c)<\/td>\n<td class=\"rtecenter\" style=\"text-align: center;\">115<\/td>\n<td class=\"rtecenter\" style=\"text-align: center;\">5.1<\/td>\n<\/tr>\n<tr>\n<td class=\"rtecenter\" style=\"text-align: center;\">Jus d'orange avec citrate de calcium malate&nbsp;<\/td>\n<td class=\"rtecenter\" style=\"text-align: center;\">250 ml (1 c)<\/td>\n<td class=\"rtecenter\" style=\"text-align: center;\">300<\/td>\n<td class=\"rtecenter\" style=\"text-align: center;\">36.3<\/td>\n<\/tr>\n<tr>\n<td class=\"rtecenter\" style=\"text-align: center;\">Boisson de soja (enrichie en phosphate tricalcique)<\/td>\n<td class=\"rtecenter\" style=\"text-align: center;\">250 ml (1 c)<\/td>\n<td class=\"rtecenter\" style=\"text-align: center;\">300<\/td>\n<td class=\"rtecenter\" style=\"text-align: center;\">24<\/td>\n<\/tr>\n<tr>\n<td class=\"rtecenter\" style=\"text-align: center;\">Boisson de soja (enrichie en carbonate de calcium)<\/td>\n<td class=\"rtecenter\" style=\"text-align: center;\">250 ml (1 c)<\/td>\n<td class=\"rtecenter\" style=\"text-align: center;\">300<\/td>\n<td class=\"rtecenter\" style=\"text-align: center;\">21.1<br \/>&nbsp;<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Source : savoirlaitier.ca<\/p>\n<p>Il est important de savoir que certains nutriments agissent comme des activateurs ou des inhibiteurs de la biodisponibilit\u00e9.
