Ricercatori dell'università svedese di Uppsala, che da anni stanno studiando il DNA delle persone alla ricerca di spiegazioni sui tratti del corpo complessi come il peso, hanno scoperto sette nuovi geni legati all'obesità.
L'obiettivo della ricerca, pubblicata dalla rivista Nature Genetics, era in particolare quello di capire se sono (o meno) sempre gli stessi geni a determinare il rischio di divenire sovrappeso.
E' stato quindi scoperto che le persone gravemente obese hanno un numero maggiore di "mutazioni" (ma queste sono dello stesso tipo) rispetto a individui con un peso più o meno nella norma.
