Kwa anthu ena, kudya kamodzi kokha keke ya chokoleti kapena chidutswa chimodzi cha m'thumba ndizosatheka. Komabe, zomwe mumadya tsiku lililonse, ndizofunika kwambiri kuti mukonze shuga, malinga ndi kafukufuku watsopano.
Asayansi akuganiza kuti kukhumba kwakukulu kwa zakudya zopanda pake ndi kumwa mankhwala osokoneza bongo ndi zofanana kwambiri kuposa zomwe munthu angaganize.
Ofufuza pa Scripps Research Institute ku Florida asonyeza kuti nthawi yoyamba kuti kudya mopitirira muyeso kumayambitsa kusintha komweko pa khalidwe ndipo ubongo umagwiritsira ntchito mankhwala osokoneza bongo.
"Zomwe apezazi zikutsimikizira zomwe ife ndi ena ambiri timakayikira - kuti zakudya zopanda thanzi zimayambitsa mayankho ngati bongo muubongo ndipo zitha kuyambitsa kunenepa kwambiri," akutero wolemba kafukufuku Paul Kenny, pulofesa wa ma molecular therapeutics ku Scripps Research Institute.
Kuti adziwe chomwe chimayambitsa vutoli, Kenny ndi mnzake Paul Johnson adasanthula momwe makoswe amadyera. Ofufuzawo anagawa makoswe m'magulu atatu: Gulu limodzi lidalandira zakudya zopatsa thanzi zamasamba; gulu lachiwiri limadya zakudya zamafuta, zopatsa mphamvu kwambiri - zomwe anthu amachita monga nyama yankhumba ndi cheesecake - ndipo gulu lachitatu limalandira chow yathanzi, kupatula mwayi wopeza zakudya zopanda pake kwa ola limodzi tsiku lililonse.
gulu adapeza kuti nyama zomwe zidadyedwa tsiku lonse zidayamba kudya mopitirira muyeso, kudya ma calorie owirikiza kawiri kuposa makoswe omwe amadya chakudya chopatsa thanzi, ndikuyamba kuchuluka m'milungu ingapo. Wotsutsa ndikuti makoswe onenepa kwambiri amapitiliza kudya zakudya zopanda pake mopitilira muyeso ngakhale kutero kungapangitse kuti makoswe agwedezeke pamagetsi.
"Khalidwe lokakamiza lotereli ndi lomwe timawona mwa omwe amakonda kugwiritsa ntchito mankhwala osokoneza bongo," akutero Kenny.
Ng'ombe zomwe zinkasowa zakudya zopanda thanzi zinayamba kudya kwambiri, zimadya makilogalamu awo muwindo la ola limodzi lokha.
Komabe, makoswewo sanakhale obirira, kusonyeza kuti kunenepa kungagwirizane kwambiri ndi kukakamiza, osati kudya, kudya, Kenny zolemba.
Kenaka, ochita kafukufuku anafuna kuona momwe kusintha kwa mitsempha kameneka kunachitikira mu ubongo wa makoswe obisa.
Iwo ankaika maganizo pa khungu la ubongo, lotchedwa dopamine yomwe yasonyezedwa kuti imakhala ndi gawo lofunika kwambiri mukumwa mankhwala osokoneza bongo. Cholandiracho chimagwira ntchito yokakamiza dopamine, mankhwala omwe amasulidwa mu ubongo pa nthawi yosangalatsa, monga kugonana, kapena kudya zakudya kapena mankhwala osokoneza bongo.
Ofufuzawo adapeza kuti kudya zakudya zopanda pake kunayambitsa kusefukira kwa dopamine muubongo. Pomwe malo osangalatsa a mbewa adadzaza ndi dopamine, ubongo wake udayamba kusintha pochepetsa zochitika za olandila, Kenny akuti. Pamene malo osangalalirowa sanamvetsere, khosweyo mwachangu adayamba zizolowezi zopewera kusiya, ndikudya chakudya chochuluka mpaka chimakhala wonenepa.
Ofufuzawo anapanga makoswe kuti azikhala ndi zochepa zochereza ndi kuzidyetsa zakudya zopanda malire zopanda malire. Bingo! Nyamazo zinakhala zovuta kwambiri kudya kwambiri usiku wonse.
"Izi zitha kutanthauza kuti anthu obadwa ndi zolandilira zochepa amakhala osavuta kudya kapena mankhwala osokoneza bongo," akutero Kenny.
Ngakhale kuti gululi silinayambe njira yothetsera kuledzera, Kenny akusonyeza kuti kumvetsetsa njira yobweretsera tsatanetsatane wa mankhwalawa kungathandize kupanga njira zothandizira kuti mukhale wonenepa kwambiri.
"Tikukhulupirira, tsiku lina tidzatha kusintha njira zosokoneza bongo," akutero Kenny.
