La sostanza \u00e8 pi\u00f9 efficace in quantit\u00e0 ridotte che in misura eccessiva<\/span>
Bastano piccole dosi di resveratrolo per prevenire il cancro intestinale. La sostanza, contenuta nell’uva, nei frutti rossi, nelle mele e nel vino, fa bene anche se presa in quantit\u00e0 ridotte. Anzi, un consumo ridotto risulta pi\u00f9 efficace di un’assunzione eccessiva. \u00c8 quanto sostengono, in uno studio pubblicato sulla rivista Science Translational Medicine, i ricercatori delle Universit\u00e0 di Leicester (Usa) e di Liverpool (Regno Unito), che hanno smentito i risultati di ricerche precedenti, secondo cui la sostanza avrebbe effetti benefici solo se consumata in quantit\u00e0 spropositate. Gli esperti ritengono, invece, che bere regolarmente un bicchiere di vino rosso potrebbe ridurre il pericolo di sviluppare il tumore all’intestino.<\/span><\/p>\n

Durante la ricerca, gli studiosi hanno somministrato il resveratrolo ad alcuni topi affetti da adenoma al colon, un tumore benigno che, in diversi casi, pu\u00f2 trasformarsi in cancro intestinale. I roditori sono stati inseriti in due gruppi. Ai primi \u00e8 stata assegnata, quotidianamente, una quantit\u00e0 della sostanza pari a quella contenuta in un bicchiere di vino. Ai secondi, invece, \u00e8 stata fornita una dose 200 volte superiore. Inoltre, gli animali sono stati ulteriormente suddivisi in due sottogruppi: alcuni sono stati nutriti con una dieta bilanciata, mentre gli altri con un’alimentazione ricca di grassi.<\/p>\n

Al termine dell’esperimento, \u00e8 emerso che il resveratrolo aveva determinato una riduzione delle dimensioni del tumore, soprattutto se assunto in piccole dosi. Nei roditori che avevano consumato elevate quantit\u00e0 della sostanza, infatti, il tumore era diminuito del 25%. Invece, in quelli che avevano consumato una dose di resveratrolo equivalente a quella contenuta in un bicchiere di vino, si era ridotto del 50%. Tuttavia, questi risultati sono stati osservati soltanto nei topolini nutriti con l’alimentazione ipercalorica.<\/p>\n

\u201cAbbiamo osservato che un basso consumo, piuttosto che un’assunzione ingente, di resveratrolo impedisce la crescita tumorale nei topi – spiega Karen Brown, che ha guidato la ricerca -. Per la prima volta, abbiamo visto che meno resveratrolo \u00e8 meglio. Questo studio dimostra che una quantit\u00e0 ridotta pu\u00f2 aiutare a prevenire i tumori pi\u00f9 di una dose elevata”.<\/p>\n","protected":false},"excerpt":{"rendered":"
