U ntse u ja lijo, empa monko o monate oa li-popcorn sebakeng sa kamohelo ea libaesekopo se baka takatso e bonahalang e ke ke ea hanyetsoa.
Ka metsotsoana e seng mekae, u se u laetse tanka ea lintho mme u jele liatla tse 'maloa.
Ho susumetsa, kapa ho araba ntle le ho nahana ka litlamorao tsa ketso, ho hokahane le ho fetella ho ja lijo, ho itlopa lijo, boima ba 'mele le botenya, hammoho le tse 'maloa mafu a kelello Ho akarelletsa ho lemalla lithethefatsi le papali ea chelete e ngata.
Sehlopha sa bafuputsi se kenyelletsang setho sa lefapha la bongaka Univesithing ea Georgia joale se khethollotse potoloho e itseng bokong e fetolang lijo ho se tsotelle, ho theha monyetla oa hore bo-rasaense ba ka khona ka letsatsi le leng ho hlahisa mekhoa ea ho phekola ho nona.
Liphetho tsa sehlopha li phatlalalitsoe haufinyane koranteng Nature Communications.
Emily Noble, motlatsi oa moprofesa UGA College of Family and Consumer Sciences ea neng a sebetsa e le mongoli ea ka sehloohong pampiring, o re: "Ho na le 'mele oa' mele o laolang bokhoni ba hau ba ho hana ho ja (ho ja ka lepotlapotla)." "Mefuteng ea liteko, o ka kenya tšebetsong methati eo mme o fumane karabelo e ikhethang ea boits'oaro."
Ho sebelisa a mohlala oa rat, bafuputsi ba tsepamisitse mohopolo karolong e ka tlase ea lisele tsa boko tse hlahisang mofuta oa phetisetso ho hypothalamus e bitsoang melanin concentrating hormone (MCH).
Le ha lipatlisiso tsa pejana li bonts'itse hore ho phahamisa maemo a MCH bokong ho ka eketsa takatso ea lijo, thuto ena ke ea pele ho bonts'a hore MCH le eona e bapala karolo ea boitšoaro bo sa susumetseng, Noble o boletse.
"Re fumane hore ha re kenya tšebetsong lisele tse bokong tse hlahisang MCH, liphoofolo li ba le tšekamelo e kholo ea boitšoaro ba tsona mabapi le lijo," ho boletse Noble.
E le ho leka ho tsilatsila, bafuputsi ba koetlisitse likhoto ho hatella lever ho fumana "monate, mafura a mangata, tsoekere e phahameng", Noble o boletse. Leha ho le joalo, rat e ile ea tlameha ho ema metsotsoana e 20 lipakeng tsa likhatiso tsa lever. Haeba rat e hatella lever kapele haholo, e tlameha ho ema metsotsoana e meng e 20.
Joale bafuputsi ba ile ba sebelisa mekhoa e tsoetseng pele ho kenya ts'ebetsong tsela e itseng ea MCH neural ho tloha hypothalamus ho ea hippocampus, e leng karolo ea boko e amehang ka ho ithuta le ho hopola mesebetsi.
Liphetho li bonts'itse MCH ha e ame hore na liphoofolo li rata lijo hakae kapa hore na li ikemiselitse ho sebeletsa lijo ka thata hakae. Ho e-na le hoo, potoloho e sebelisitse taolo ea liphoofolo, kapa bokhoni ba bona ba ho itšireletsa ho leka ho fumana lijo. ”Ho kenya tšebetsong tsela ena e khethehileng ea MCH neurons ho ekelitse boits'oaro ntle le ho ama lijo tse tloaelehileng bakeng sa tlhoko ea kalori kapa tšusumetso ea ho ja lijo tse monate, ”Noble o boletse. “Ho utloisisa hore potoloho ena, e amang ka khetho lijo ho se be le takatso e matla, ho re bulela monyetla oa hore ka letsatsi le leng re tla khona ho hlahisa mekhoa ea ho phekola bakeng sa ho ja ho tlōla tekano e tla thusa batho ho khomarela lijo ntle le ho fokotsa takatso e tloaelehileng ea lijo kapa ho etsa hore lijo tse hlabosang li se ke tsa ba monate hakaalo. ”
