<prompt> Fingqa isihloko: Ososayensi baye bathola ukuthi ukubheka umuntu okhuluphele ngokweqile noma okhuluphele ngokweqile kungashintsha umuzwa wethu wokunuka ukuze senze iphunga lezwe elisizungezile libonakale lingathandeki kangako. Abacwaningi bathola ukuthi ukubuka izithombe zabantu abakhuluphele kwabangela abahlanganyeli ocwaningweni ukuba babheke amasampula anuka kabi - nakuba ayengenalo iphunga. Ososayensi bakholelwa ukuthi lokhu kungabangelwa ukucwaswa okungathandeki abantu abaningi abanakho ngalabo abakhuluphele ngokweqile. Ingabe ukubuka lesi sithombe sendoda ekhuluphele ebhentshini kukwenza ube nephunga elibi? Ungase ube nokubandlulula okwakhelwe ngaphakathi uma kunjalo, ngokusho kocwaningo olusha olwenziwa ososayensi e-University of California, eLos Angeles. Ngokumangalisayo, bathola nokuthi labo ababenama-BMI aphakeme bona ngokwabo babevame ukunikeza amasampula anuka kamnandi izilinganiso eziphansi. Lokhu kusikisela ukuthi abantu abanenkinga yabo siqu yokukhuluphala mhlawumbe futhi bangabagxeki abanokhahlo kakhulu ngabanye abakhuluphele. Ukuhlala phansi kusiza ukuqinisa isisu sakho, kuyilapho ukuma phansi kuqinisa imilenze yakho nezinsana zakho - kodwa izibambo zothando kunzima kakhulu ukuzishintsha. Manje ososayensi bakholelwa ukuthi sebethole indlela yokuncibilikisa amafutha amhlophe ayengeziwe asezingxenyeni eziphezulu zama-muffin ngokuwenza abe nsundu. Nakuba amangqamuzana amhlophe engqamuzaneni engqamuzaneni engqamuzaneni. Ukuze benze amangqamuzana amhlophe aziphathe njengangqamuzana ansundu, abacwaningi baseNyuvesi yaseBonn bathola indlela entsha yokwazisa. Ngokuhlola amagundane, uProfesa Alexander Pfeifer we-Institute of Pharmacology and Toxicology e-University Hospital Bonn wathola indlela entsha yokubonisa i-molecule ebizwa ngokuthi i-adenosine. I-adenosine yaziwa ngokuthi ivuselela amangqamuzana amafutha ansundu, futhi ngokuvamile ikhishwa lapho umuntu ecindezelekile. Isignali ye-adenosine idluliselwa yi-adenosine receptor A2A. Uma i-adenosine ibopha le-receptor emangqamuzaneni amafutha ansundu, ukushiswa kwamafutha kuvuselelwa ngokuphawulekayo. Abacwaningi badlulisela ama-A2A receptors kusuka kumaseli amafutha ansundu kuya kumaseli amafutha amhlophe kumagundane futhi bathola ukuthi aqala ukushisa amafutha amaningi. UDkt. Ayako Tomiyama, um...  <response>: Ososayensi e-University of California, eLos Angeles benza lolu cwaningo. Abahlanganyeli babebheka iphunga elibi kakhulu lapho bebuka izithombe zabantu abakhuluphele. Abantu ababekhuluphele ngokwabo babezihlulela kabi kakhulu izihogo. Izazi zokusebenza kwengqondo zithi kungenzeka ukuthi kuwumphumela wokuthambekela okungokwemvelo ngokumelene nokukhuluphala. Bathi ukungathandwa kokukhuluphala okungaqondakali kungase kubonakale njengokuhogela.
