L’olio d’oliva protegge da danni epatici

L’olio d’oliva è sicuramente uno degli alimenti che meglio rappresenta la dieta mediterranea, ultimamente al centro di molti dibattiti perché identificata come regime alimentare perfetto per tutelare la salute dai rischi dell’obesità. Dell’olio sappiamo tante cose, prima di tutto che è antiossidante e che previene il tumore.  La novità però è che è in grado di ridurre anche i danni al fegato. Questo è quanto ha scoperto un gruppo di ricercatori dell’University of Monastir (Tunisia) e della King Saud University di Riyadh (Arabia Saudita) guidati Mohamed Hammami.

La ricerca è stata svolta su 180 topolini a cui era stata indotta epatotossicità tramite la somministrazione di alcuni erbicidi moderatamente tossici. Le cavie sono state prima divise in 8 gruppi e poi esposti a un erbicida tossico, provocando danni epatici significativi in tutti gli esemplari.

I medici hanno poi somministrato agli animaletti diversi estratti dell’olio d’oliva, gruppo per gruppo: ed è emerso che in tutti i gruppi si registravano segni di miglioramento nella salute del fegato, ma che in particolare l’estratto idrofilo dell’olio si è dimostrata la sostanza più in grado di attivare gli enzimi antiossidanti e di diminuire i marker del danno epatico. A tal proposito, Mohamed Hammami ha dichiarato:

L’olio di oliva è un ingrediente fondamentale nella dieta mediterranea, e abbiamo sempre più che può avere grandi benefici per la salute, tra cui la riduzione del rischio di malattia coronarica, la prevenzione di alcune forme di cancro e la modifica delle risposte immunitarie e infiammatorie Grazie a questo studio abbiamo dimostrato che è anche in grado di proteggere contro il danno ossidativo del tessuto epatico.
