MELBOURNE, Australia — Chomera cha rosella chomwe chimadyedwa kwambiri chili ndi ma antioxidants omwe ofufuza aku Australia amakhulupirira kuti angathandize kuchepetsa thupi. Malinga ndi kafukufuku watsopano, ma antioxidants ndi ma organic acid omwe ali mu hibiscus amatha kuletsa bwino kupangika kwa maselo amafuta. Kukhala ndi mafuta ena ndikofunikira powongolera mphamvu ndi shuga m'thupi, koma mafuta akakhala ambiri, thupi limasintha mafuta ochulukirapo kukhala maselo amafuta otchedwa adipocytes. Anthu akamapanga mphamvu zambiri popanda kugwiritsa ntchito, maselo amafuta amawonjezeka kukula ndi kuchuluka, zomwe zimapangitsa kuti awonjezere kunenepa komanso kunenepa kwambiri.
Mu kafukufuku waposachedwa, gulu la RMIT linachiza maselo a tsinde la munthu ndi zotulutsa za phenolic ndi hydroxycitric acid asanasanduke maselo amafuta. M'maselo omwe ali ndi hydroxycitric acid, palibe kusintha kwa kuchuluka kwa mafuta m'maselo a adipocyte komwe kunapezeka. Kumbali inayi, maselo omwe adalandira phenolic extract anali ndi mafuta ochepa ndi 95% kuposa maselo ena.
Mankhwala ochiritsira kunenepa kwambiri omwe alipo panopa akuyang'ana kwambiri kusintha kwa moyo ndi mankhwala. Ngakhale kuti mankhwala amakono ndi othandiza, amawonjezera chiopsezo cha kuthamanga kwa magazi komanso kuwonongeka kwa impso ndi chiwindi. Zotsatira zake zikusonyeza kuti zotulutsa za hibiscus zomwe zimapangidwa ndi zomera zitha kupereka njira yachilengedwe komanso yothandiza yochepetsera kulemera.
Ben Adhikari, pulofesa ku RMIT Center for Nutritional Research, anati: “Zotulutsa za hibiscus phenolic zingathandize kupanga chakudya chabwino chomwe sichimangothandiza poletsa kupanga maselo amafuta, komanso kupewa zotsatira zoyipa za mankhwala ena. Innovation Center, mu lipoti la atolankhani.
Pali chidwi chowonjezeka chofuna kuphunzira za ubwino wa mankhwala a polyphenolic okhala ndi ma antioxidants ambiri pa thanzi. Amapezeka mu mitundu yambiri ya zipatso ndi ndiwo zamasamba. Anthu akamadya, ma antioxidants amachotsa mamolekyu oopsa a oxidative m'thupi omwe amathandizira kukalamba ndi matenda osatha.
Kafukufuku wakale pa ma polyphenols omwe ali mu hibiscus wasonyeza kuti amagwira ntchito ngati zoletsa ma enzyme achilengedwe, mofanana ndi mankhwala ena oletsa kunenepa kwambiri. Ma polyphenols amaletsa enzyme yogaya chakudya yotchedwa lipase. Puloteni iyi imagawa mafuta m'magawo ang'onoang'ono kuti matumbo athe kuyamwa. Mafuta ochulukirapo amasanduka maselo amafuta. Zinthu zina zikaletsa lipase, mafuta sangalowe m'thupi, zomwe zimapangitsa kuti adutse m'thupi ngati zinyalala.
“Popeza mankhwala a polyphenolic awa amachokera ku zomera ndipo amatha kudyedwa, payenera kukhala zotsatirapo zochepa kapena zopanda vuto lililonse,” akutero wolemba wamkulu Manisa Singh, wophunzira wa RMIT. Gululo likukonzekera kugwiritsa ntchito hibiscus phenolic extract mu chakudya chopatsa thanzi. Asayansi azakudya amathanso kusintha chotsitsacho kukhala mipira yomwe ingagwiritsidwe ntchito mu zakumwa zotsitsimula.
"Zotulutsa za phenolic zimasungunuka mosavuta, kotero kuziyika m'maselo sikuti zimangowonjezera nthawi yawo yosungira, komanso kumatithandiza kulamulira momwe zimatulutsidwira ndikuyamwa ndi thupi," adatero Adhikari. "Ngati sitiyika m'maselo, zimatha kusweka m'mimba tisanapindule."
