Una dieta ricca di mele e pomodori può aiutare gli ex fumatori a riparare i polmoni provati dal vizio e rallentarne il naturale declino dovuto all'età.
Lo rivela giovedì una ricerca condotta presso la Johns Hopkins Bloomberg School of Public Health di Baltimora. Lo studio è stato pubblicato sulla rivista European Respiratory Journal e condotto nell'ambito del progetto di ricerca Ageing Lungs in European Cohorts (ALEC) Study, finanziato dalla Commissione Europea e coordinato dall'Imperial College di Londra.
Gli esperti hanno coinvolto oltre 650 persone, ex fumatori e non fumatori. Hanno valutato il loro consumo di frutta e verdura con questionari ad hoc misurando la loro funzione polmonare con esami specifici come la spirometria, sia all'inizio dello studio sia 10 anni dopo. "L'effetto protettivo sui polmoni si vede con consumi giornalieri di almeno due pomodori e di almeno tre porzioni di frutta, la mela in particolare", sostiene l'autrice dello studio, Vanessa Garcia-Larsen.
