Abstract

De manière classique, des suggestions concernant des aliments conservés impliquaient la possibilité de provoquer des stocks excédentaires en raison d'un manque de considération des nutriments dans les stocks actuels, ou l'on ignorait combien de temps de longues pénuries d'achats pouvaient être évitées en raison d'un manque de considération de l'apport en nutriments passé.　Un réfrigérateur (1) qui conserve des aliments, le réfrigérateur étant un exemple d'un appareil de gestion de zones selon la présente invention permettant de résoudre le problème mentionné ci-dessus, comprend : une unité d'identification (124) qui identifie l'état d'utilisation de zones de gestion dans le réfrigérateur (1) ; une unité de calcul d'indice de santé (126) qui spécifie des nutriments dont l'apport est recommandé à un utilisateur prescrit et calcule un indice de santé correspondant à ces nutriments sur la base de l'état d'utilisation susmentionné ; et une unité d'affichage (128) qui affiche l'indice de santé.
