Kuyaziwa ukuba izixa ezikhulu zotywala zibangela uxinzelelo lwegazi oluphezulu. Uphononongo olwenziwe ngabaphandi kwiYunivesithi yase-Linköping ngoku lubonisa ukuba nemilinganiselo emincinci yotywala inyusa uxinzelelo lwegazi. Abantu abasabela kakhulu babonisa iimpawu zokuxinezeleka kwentliziyo.

I-Liquorice iveliswa kwingcambu yezityalo zeGlycyrrhiza kwaye kudala isetyenziswa njengeyeza lezityalo kunye nencasa. Nangona kunjalo, kuyaziwa ukuba ukutya i-liquorice kunokunyusa uxinzelelo lwegazi. Oku kubangelwa ikakhulu yinto ebizwa ngokuba yi-glycyrrhizic acid echaphazela ibhalansi yolwelo lomzimba ngeempembelelo kwi-enzayimi ezintso. Uxinzelelo lwegazi oluphezulu, kwandisa umngcipheko wesifo senhliziyo.
Zombini i-European Union kunye ne-World Health Organisation ziye zagqiba kwelokuba i-100 mg ye-glycyrrhizic acid ngosuku ikhuselekile ukuba ingatyiwa ngabantu abaninzi. Kodwa abanye abantu batya utywala obuninzi kunoko. I-Arhente yoKutya yaseSweden iqikelele ukuba i-5 pesenti yabantu baseSweden banokuthatha okungaphezulu kweli nqanaba.
Ngaba umda ukhuselekile?
Kuphononongo lwangoku, olupapashwe kwi I-American Journal of Clinical Nutrition, abaphandi kwiYunivesithi yase-Linköping bafuna ukuvavanya ukuba umda ochazwe njengokhuselekile ngokwenene unjalo okanye akunjalo.
Akulula ukwazi ukuba ingakanani i-glycyrrhizic acid kwi-liquorice oyidlayo, njengoko ukugxininiswa kwayo kwiimveliso zotywala ezahlukeneyo kuyahluka kakhulu. Olu tshintsho lunokuxhomekeka kwizinto ezifana nemvelaphi, iimeko zokugcina kunye neentlobo zeengcambu zotywala. Ukongezelela, inani le-glycyrrhizic acid aliboniswa kwiimveliso ezininzi. Uphononongo lweYunivesithi yase-Linkoping ngowokuqala ukulinganisa ngononophelo inani le-glycyrrhizic acid kwi-liquorice eyavavanywa, ngelixa i-randomized kwaye ineqela lokulawula.
Watya utywala iiveki ezimbini
Kuphononongo, i-28 yabasetyhini kunye namadoda aneminyaka eyi-18-30 bayalelwa ukuba badle i-liquorice, okanye imveliso yokulawula eyayingenayo nayiphi na i-liquorice, ngaphezu kwamaxesha amabini. Imveliso yolawulo endaweni yoko iqulathe isalmiak, enika utywala obunetyuwa incasa yayo. I-liquorice inobunzima be-3.3 grams kwaye iqulethe i-100 mg ye-glycyrrhizic acid, oko kukuthi, isixa esibonakaliswe njengento ekhuselekileyo kubantu abaninzi ukuba badle imihla ngemihla. Abathathi-nxaxheba babelwa ngokungenamkhethe ukuba batye i-liquorice okanye imveliso yokulawula iiveki ezimbini, bathathe ikhefu kwiiveki ezimbini, baze batye ezinye iindidi kwiiveki ezimbini. Oku kwenza abaphandi bakwazi ukuthelekisa umphumo wazo zombini iindidi kumntu omnye. Abathathi-nxaxheba kuphononongo bacelwa ukuba balinganise uxinzelelo lwegazi ekhaya yonke imihla. Ekupheleni kwexesha ngalinye lokuthatha, abaphandi balinganisa amanqanaba eehomoni ezahlukeneyo, ibhalansi yetyuwa, kunye nomsebenzi wentliziyo.
“Kuphononongo, sifumanise ukuba ukusela yonke imihla utywala obune-100 mg glycyrrhizic acid kunyuse uxinzelelo lwegazi kubantu abancinci abasempilweni. Oku akuzange kuboniswe ngaphambili ngezixa ezincinci zotywala, "utsho uPeder af Geijerstam, umfundi ogqirha kwiSebe lezeMpilo, iMedicine kunye neSayensi yokuKhathalela kwiYunivesithi yase-Linköping, ugqirha jikelele, kunye nombhali okhokelayo wophononongo.
Xa abathathi-nxaxheba besitya utywala, uxinzelelo lwegazi lonyuka ngomyinge we-3.1 mmHg.
Abanye babenobuntununtunu
Abaphandi baye balinganisa iihomoni ezimbini ezichatshazelwa yi-liquorice kwaye zilawula ibhalansi yolwelo: i-renin kunye ne-aldosterone. Amanqanaba ezi zinto zombini ehlile xa kutyiwa utywala. Ikota yabathathi-nxaxheba kuphononongo ababenovakalelo kakhulu, ngokusekwe kumanqanaba eehomoni ze-renin kunye ne-aldosterone ehla kakhulu emva kokutya i-liquorice, nabo bafumene ubunzima obuncinci, okunokwenzeka ngenxa yokonyuka kolwelo emzimbeni. Eli qela lalinamanqanaba aphakamileyo eprotheni ukuba intliziyo ifihla ngakumbi xa kufuneka isebenze nzima ukumpompa igazi elijikelezayo emzimbeni, i-N-terminal pro-brain natriuretic peptide (NT-proBNP). Oku kuphakamisa umthamo wolwelo olwandisiweyo kunye nomsebenzi wentliziyo kubantu abanovelwano kakhulu kwiziphumo zotywala.
"Iziphumo zethu zinika isizathu sokuba silumke ngakumbi xa kufikwa kwiingcebiso kunye nokuleyibhelilwa kokutya okune-liquorice," utshilo uFredrik Nyström, unjingalwazi kwisebe elifanayo, owayenoxanduva lophononongo.
Uphononongo luxhaswe ngenkxaso evela, phakathi kwabanye, i-Strategic Research Network kwi-Circulation and Metabolism (LiU-CircM) kwiYunivesithi yase-Linköping, iSikolo soPhando seSizwe kwi-General Practice kwiYunivesithi yase-Umeå, uKumkani uGustaf V kunye no-Queen Victoria Freemason Foundation kunye nommandla we-Östergötland. .
I sihloko: Idosi ephantsi ye-licorice yemihla ngemihla ichaphazela i-renin, i-aldosterone, kunye noxinzelelo lwegazi lwasekhaya kulingo lwe-crossover olungahleliwe., Peder af Geijerstam, Annelie Joelsson, Karin Rådholm kunye noFredrik Nyström, (2024).
