Riaan Ngalokho ekuseni inkomishi yekhofi ingase inikeze izinzuzo eziningi kunokwenyuka kwamandla okusheshayo. Ucwaningo olusha lubonisa ukuthi ukudla amazinga aphezulu e-caffeine kungasiza ukunciphisa amafutha omzimba futhi kunciphise ingozi yokuba nesifo sikashukela sohlobo 2.
Abacwaningi eNyuvesi yaseBristol, i I-Karolinska Institute eSweden kanye ne-Imperial College eLondon yenze lolu cwaningo, olwanyatheliswa kumagazini i-BMJ Medicine.
Ukuhlaziya idatha yofuzo evela kubantu base-Europe abangu-9,876 ababambe iqhaza ezifundweni eziyisithupha ezahlukene zesikhathi eside, abacwaningi baqaphe ngokukhethekile izakhi zofuzo ze-CYP1A2 ne-AHR, ezithonya izinga umzimba ozosebenzisa ngalo i-caffeine.
UKUPHUZA IKHOFU NSUKU ZONKE UNGANWULA IMPILO YAKHO: UCWANINGO ELISHA
Labo ababenezakhi zofuzo ezakha i-caffeine ngesilinganiso esisheshayo bahlotshaniswa nokuba ne-low body mass index (BMI) kanye nesisindo somzimba wonke esiphansi samafutha.
Baphinde kwatholakala ukuthi ingozi enciphile uhlobo 2 sikashukela.

Umbhali-mbhali wocwaningo uDkt Benjamin Woolf, udokotela wefilosofi eSikoleni Sesayensi Yengqondo eNyuvesi yaseBristol, ukuqinisekisile ukuthi imiphumela isekela ukuhlangana kokubuka phakathi kokusetshenziswa kwe-caffeine nesifo sikashukela sohlobo lwe-2.
I-FDA ithi amamiligremu angu-400 e-caffeine ngosuku (cishe izinkomishi ezine noma ezinhlanu zekhofi) iyinani eliphephile.
“Kwangimangaza mathupha ukuthi kungakanani lokhu okwalamula ukwehla kwesisindo,” etshela iFox News Digital nge-imeyili.
UDkt. Bradley Serwer, isikhulu sezokwelapha seCardioSolution eBethesda, eMarylandakazange ahileleke ocwaningweni kodwa akazange athole imiphumela imangalisa.
“Kusebenzisa inhlanganisela yezimpawu zofuzo namazinga e-caffeine e-plasma, lolu cwaningo lusisiza ukuba siqonde imiphumela ye-caffeine ngezinga elijulile,” kusho esinye isikhulu sezokwelapha esiyinhloko. (iStock)
“Izifundo eziningana zibonise ukuhlangana phakathi kwe-caffeine kanye ingozi encishisiwe yokukhuluphala nesifo sikashukela, kodwa lolu cwaningo luthatha isinyathelo esilandelayo ukukhombisa imbangela,” etshela iFox News Digital ku-imeyili.
“Ukusebenzisa ingxube yezimpawu zofuzo namazinga e-caffeine e-plasma, lolu cwaningo lusisiza ukuba siqonde imiphumela ye-caffeine ezingeni elijulile,” waqhubeka udokotela. “Nakuba le datha ingacacile futhi yenziwa ngokuyinhloko eqenjini elilodwa kuphela, iyathakazelisa kakhulu futhi ishukumisa ingqondo.”
Ochwepheshe baxwayisa ngezingozi ezingase zibe khona
Izinzuzo ze-caffeine kufanele zikalwe ngokumelene nemiphumela yayo engemihle engaba yingozi, njengoba uDkt. Ahmet Ergin, a Isekelwe eFlorida i-endocrinologist enolwazi olukhethekile ekunakekelweni kwesifo sikashukela, itshele iFox News Digital.
UDkt Ergin akazange ahlanganyele ocwaningweni.

“Nakuba sekunesikhathi eside kubizwa ngokuthi i-elixir yokuphila, i-caffeine ingaba nemiphumela engemihle engase ibe yingozi uma ixhashazwa futhi isetshenziswa ngokweqile,” esho. “Ukusebenzisa i-caffeine ngokweqile kungaholela ekuqwaleniukushaya kwenhliziyo ngisho nezinkinga zokuziphatha.”
I-Food & Drug Administration (FDA) incoma ukunamathela kumamiligremu angama-400 e-caffeine ngosuku.
Lokho kulingana nezinkomishi ezine kuya kweziyisihlanu zekhofi – kodwa uDkt. Ergin waveza ukuthi abantu abahlukene basabela ngendlela ehlukile ku-caffeine kuye ngokuthi i-metabolism yabo, ukubekezelelana nokuzwela.
ABASHIYA IKHOFI ABANGATHOLA USIZO OLUNYE: UDASI WE-DECAF UNGASIZA EKWEHLISA IZIMPAWU ZOKUHOXA
UDkt. Serwer waseMaryland wengeze ngokuthi nakuba i-caffeine iye yaxhunyaniswa nenani lezinzuzo, iseyisikhuthazo.

“Abanye abantu abasengozini yokuthola i-cardiac arrhythmias kanye izifo zengqondo – okufana nokuqwasha, ukusangana noma ukuphazamiseka kwengqondo okuguquguqukayo – kungenzeka kungawubekezeleli umuthi futhi kungaba nezigameko ezingezinhle,” waxwayisa.
I-caffeine ngaphambilini yayixhunyaniswa nengozi ephansi yesifo senhliziyo
Lolu akulona ucwaningo lokuqala lokugqamisa izinzuzo zezempilo ezingaba khona ze-caffeine.
Ucwaningo oluningi luye lwaphakamisa izixhumanisi phakathi kokusetshenziswa kwekhofi kanye nengozi ephansi ye isifo senhliziyo, Kusho uDkt Egin.
“Ucwaningo lukhomba ukuthi abadla izinkomishi ezintathu kuya kweziyisihlanu ngosuku banamathuba amancane okuba nesifo senhliziyo nesifo sohlangothi uma kuqhathaniswa nabangaphuzi ikhofi,” usho kanje.
“I-caffeine ingaba nemiphumela engemihle engase ibe yingozi uma ixhashazwa futhi isetshenziswa ngokweqile.”
“Okunye okutholakele kubonise ukuthi abaphuza ikhofi abalinganiselayo bangase futhi banciphise amathuba abo okuthuthukisa ukuhluleka kwenhliziyo, nakuba kubonakala kungenamthelela ku-fibrillation ye-atrial.”
Ucwaningo lube nezixwayiso, kusho umcwaningi
Umlobi ohlanganyele wocwaningo uDkt. Woolf waveza ukuthi esikhundleni sokulinganisa umphumela oqondile wokuphuza itiye eliningi, ikhofi noma ezinye iziphuzo ezine-caffeine, ucwaningo lwabikezela amazinga e-caffeine kusetshenziswa okuhlukile kofuzo oluyishintshayo.
Abantu bathambekele ekuphuzeni ikhofi elinobisi, ushukela futhi mhlawumbe ukudla okulula – konke okungadala ukukhuluphala, kuphawula udokotela oyedwa. Lapha, umuntu wengeza ingxenye nengxenye enkomishini yekhofi. (iStock)
Ezweni langempela, waphawula, “abantu bavame ukuwaphuza nobisi, ushukela futhi ngokunokwenzeka nokudla okulula – konke okungabangela ukukhuluphala.”
Ukwengeza, uDkt. Woolf wachaza ukuthi ngenxa yokuthi izakhi zofuzo zitholwa ngofuzo lapho umuntu ekhulelwa, lolu cwaningo lwalinganisela umphumela wokuphila konke.
“Lokhu kungase kuhluke kakhulu kumphumela wesikhashana ongawubona umuntu uma eqala ukuphuza kakhulu i-caffeine ngemuva kokuthi udokotela ethe akanciphe,” usho kanje.
IKHOFU LINGENZA AKULINDE UKUPHILA KWAKHO, IZIPHAKAMISO ZEZIFUNDO
Omunye umkhawulo ukuthi ucwaningo lugxile kakhulu kubantu bomdabu wase-Europe.
Kodwa-ke, uDkt. Woolf uphinde waveza lokho akubona njengamandla angempela ocwaningo: “Ngenxa yokuthi asikhethi izakhi zethu zofuzo futhi asikwazi ukuzishintsha, imiphumela yethu mancane kakhulu amathuba okuba imele ukwenzelela kunocwaningo olujwayelekile,” esho.
Funa dokokufaka kuka-octor ngaphambi kokuqongelela i-caffeine
Kungcono ukubonana nodokotela kuqala ngaphambi kokwehlisa izinkomishi ezengeziwe zekhofi ngethemba lokwehlisa amafutha emzimbeni.
CHOFOZA LAPHA UKUZE Ubhalisele IPHEPHA LETHU LEZEMPILO
“Njenganoma yimuphi umuthi, kukhona okuhle nokubi okumele kuhlaziywe,” kusho uDkt Serwer.

“Umuntu kufanele athintane futhi axoxisane ngesihloko nomhlinzeki wezokwelapha ukuze anqume ukuthi sizobe siphephile futhi sinenzuzo … Uma uzimisele ukwamukela ubungozi futhi izinzuzo zibalulekile, khona-ke kungase kube nengqondo.”
Udokotela wengeze ngokuthi nakuba le miphumela yocwaningo ingase ibonakale ithembisa, azikho iziqinisekiso zokuthi abantu bazoncipha noma bazogwema isifo sikashukela ngokwandisa ukudla kwabo kwansuku zonke okune-caffeine.
CHOFOZA LAPHA UKUZE UTHOLA UHLELO LOKUSEBENZA IZINDABA
“Zikhona ubufakazi izindlela zokwehlisa isisindo nokwehlisa ushukela egazini elingancikile ku-caffeine,” kusho yena.
