Esikhathini esidlule, ikhofi ngokuvamile ibhekwa njengokulimaza impilo yenhliziyo. Ikhofi kuthiwa yandisa ukucindezeleka kwegazi, yandisa amazinga e-cholesterol, futhi yandisa ingozi yokuhlaselwa yinhliziyo kanye nama-arrhythmias enhliziyo . Kodwa-ke, izifundo zamuva futhi eziqaphile kakhulu ziye zachaza ukuthi ikhofi cishe ayinyuli ingozi yesifo senhliziyo; futhi kwezinye izimo kungase kube nenzuzo.
Kungani ukungafani?
Ezinye izifundo zangaphambili azizange zithathe ezinye izifo zengozi yezinhliziyo zibe yanele akhawunti, njengokuntuleka kokuzivocavoca nokubhema. Ucwaningo lwamuva luye lwaqapha ukulawula lezi zici eziyingozi eziphazamisayo. Lezi zifundo zakamuva zenzakale ukuthi, uma kusetshenziselwa ukulinganisela, ikhofi ayikwenyusi ingozi yomzimba.
Ikhofi Nokucindezelwa Kwegazi
Umphumela wekhofi ekucindezelekeni kwegazi kubonakala uhlanganisiwe. Kulabo abangewona ikhofi, ukuvezwa kanzima ku-caffeine kungandisa ukwanda kwegazi ngo-10 mm Hg. ( Funda mayelana nokulinganisa umfutho wegazi .) Nokho, kubantu abaphuza ikhofi njalo, ukungenisa okujulile kwe-caffeine akubonakali ukuphakamisa umfutho wegazi. Izifundo eziningi eziningana manje sehlulekile ukukhombisa ukuhlangana phakathi kokuphuza ikhofi okungapheli nomfutho wegazi ophezulu .
Nakuba lezi zifundo eziningi zabantu ziqinisa, kubonakala sengathi abanye abantu banokwanda kwegazi lapho bephuza ikhofi eningi.
Ngakho uma uthola ukuthi unesifo sofuba, kusengqondo ukuzama ukugwema ikhofi inyanga noma ngaphezulu, ukuze ubone ukuthi ukuqeda ikhofi kuyasiza yini umfutho wegazi lakho.
Ikhofi ne-Arrhythmias
Inkolelo yokuthi ikhofi ibangela ukukhubazeka kwenhliziyo isakazeke kakhulu, ngisho naphakathi kwabachwepheshe bezokwelapha.
Futhi ngempela, kubonakala kungenakuphikwa ukuthi abanye abantu bayothola ukwanda kwamaphutha lapho bephuza ikhofi.
Kodwa-ke, akukho izifundo ezinkulu noma izifundo ezitholakala ebhokisatriji eziye zabonisa ukuthi inani elilingana lekhofi landisa ingozi ye-arrhythmias yenhliziyo. Ngempela, isifundo esivela kuKaiser Permanente siphakamise ukuthi abantu abaphuza izindebe ezine zekhofi ngosuku babencane kakhulu ama- arrhythmias enhliziyo, kuhlanganise ne -fibrillation engaphansi kwe-atrial kanye ne- PVCs embalwa.
Okungenani, ngaphandle kokuthi ungomunye walabo bantu abaqaphela ukunyuka okucacile kwamapayipi emva kokuphuza ikhofi, kubonakala sengathi asikho isizathu sokugwema inani elilinganiselwe lekhofi ngenxa yokukhathazeka nge-arrhythmias yenhliziyo.
Ikhofi nesifo sikashukela
Ucwaningo oluthile manje lubonise ukuhlanganiswa phakathi kwekhofi ukusetshenziswa kanye nengozi enciphise ye-type 2 yesifo sikashukela. Okungenani isifundo esisodwa sibonise ukuthi ukunciphisa okufanayo engozini kubonakala ngekhofi e-decaffeinated, okusikisela ukuthi umphumela wokuzivikela wekhofi, ngokuphathelene nesifo sikashukela, kungenzeka ukuthi awukwenzanga ngenxa ye-caffeine.
Ikhofi kanye nesifo sohlangothi
Ukuhlaziywa okukhulu kwe-meta okubandakanya abahlanganyeli abangaba ngu-500 000 kuhlulekile ukukhombisa noma yikuphi ukukhuphuka engozini yokushaya isifo phakathi kwabaphuza ikhofi.
Empeleni, kubantu abaphuza izinkomishi ezingu-1 kuya kwezingu-3 ngosuku, ingozi yokushaya isifo yayinciphile kakhulu.
Futhi ocwaningweni oluvela eJapane, abantu abaphuza okungenani ikhofi yekhofi ngosuku (noma izindebe ezine zetiyi eluhlaza, okuwumkhuba ovamile ngokwengeziwe eJapane) banciphise u-20% engozini yabo yokushaya isifo ngaphezulu kweminyaka engu-13 isikhathi.
Ikhofi ne-Coronary Artery Disease
Ucwaningo oluthile lwezibalo zabantu aluphumelelanga ukukhombisa noma yikuphi ukukhuphuka engozini yokugula kwesifo somugqa phakathi kwabaphuza ikhofi. Futhi kwabesifazane, ukuphuza ikhofi kungase kube nomthelela wokuvikela.
Kodwa-ke, njengoba kunjalo ngaso sonke isikhathi, kunoma yikuphi abantu abaningi kunabantu abaningi abangabonakali ukuziphatha "okujwayelekile".
Kuvela ukuthi kukhona ukuguquguquka kwezakhi zofuzo ezivame ukudala abanye abantu ukuba bahambise i-caffeine kancane kancane.
Kubonakala sengathi kulaba bantu ingozi ye-coronary artery disease ingase yande ngekhofi ukusetshenziswa. Lapho ukuhlolwa kofuzo kuba isimiso esiningi, kuzoba lula ukubona lezi ziqu zokudla kwe-caffeine.
Ikhofi ne-Cholesterol
Ikhofi iqukethe ama-compounds - ikakhulukazi into ebizwa ngokuthi i-cafestol - engayandisa amazinga egazi le- LDL ye-cholesterol . Noma kunjalo, izihlungi zamaphepha ziwasusa ngokuqinile lezi zinto ezisebenza nge-lipid. Ngakho ikhofi ephuziwe nezihlungi zephepha ayikhulisi amazinga wegazi we-cholesterol. Ngakolunye uhlangothi, ukungenisa okungapheli kwekhofi engafakiwe kungandisa ama-LDL ama-cholesterol amazinga angaphezu kuka-15 mg / dl. Ngakho-ke, ngenkathi ukuphuza ikhofi ehlanjululwayo kubonakala kunengqondo, ngokuvamile ukuphuza ikhofi engafakiwe kungase kungabi khona.
Ukuhluleka Kwekhofi Nenhliziyo
Ukuhlaziywa kwe-meta yakamuva kubonisa ukuthi abantu abaphuza izinkomishi ezingu-1 kuya kwezingu-4 ngelanga banomngcipheko wokunciphisa inhliziyo . Le nzuzo ebonakalayo yokuphuza ikhofi ilahlekile uma izinkomishi ezinhlanu noma ngaphezulu zekhofi zidliwa ngosuku.
Qaphela ukungezwani kwe-Caffeine Ukuzwela!
Nakuba lonke lolu lwazi lududuza abantu abajabulela ukuphuza i-caffeinated, kudingeka siqaphele ukuthi i-caffeine ithinta abantu abahlukene ngezindlela ezihlukene kakhulu. Ngokuyinhloko, ezinye zizwela kakhulu ngisho nangamanani amancane e-caffeine.
Abantu abanomdlavuza we-caffeine bangabhekana nama-jitters, ama-palpitations, ukulala nokunye izimpawu uma bedla i-caffeine. Laba bantu kufanele banciphise ukudla kwabo kwe-caffeine
Ukuzwela kwe-caffeine ngokuyinhloko kunqunywa umsebenzi we-CYP1A2 enzyme esibindi. Uma sisebenza ngokwengeziwe i-CYP1A2, sizwela kakhulu ukuthi siyi-caffeine. Izici eziningana zithinta umsebenzi we-CYP1A2:
- Ubudala: Umsebenzi we-CYP1A2 uthambekela ekunciphiseni ngobudala, ngakho abantu asebekhulile bavame ukuzwela kakhulu i-caffeine
- Ubulili: abesifazane bavame ukuba nomsebenzi ophansi we-CYP1A2 kunamadoda.
- Ukusetshenziswa komlomo ngokwemlomo nokukhulelwa: i-estrogens inqanda umsebenzi we-CYP1A2, futhi ukuzwela kwe-caffeine kuyanda. Ngokuvamile, abesifazane abakhulelwe kufanele bazame ukunciphisa noma ukugwema i-caffeine.
- Ukwenziwa kwe-Genetic: Kunezici eziningi ezihlukahlukene zezakhi zofuzo manje eziye zithinta umsebenzi we-CYP1A2. Nakuba ukuhlolwa kofuzo kungahlukanisa izinga lakho lokuzwela kwe-caffeine, ukuhlolwa okusemthethweni ngokuvamile akudingekile ukuba wazi - okungenani ngokuvamile ukukhuluma - noma ngabe uzwela kakhulu nge-caffeine. Futhi uma kunjalo, kungenzeka ukuthi akekho umuntu okudingeka akutshele ukuthi unqande emuva.
I-Black Coffee, noma i-Cream ne-Sugar?
Cishe zonke lezi zifundo zazibheke ikhofi yokuphuza ngaphandle kokubheka ukuthi ikhofi idliwe ukhilimu, ushukela, ezinye izithako - noma umnyama kuphela. Lokhu kunengqondo, ngoba ngabe uphuza ikhofi lakho elimnyama noma cha, izimpikiswano yilokho ovame ukuzidla nezinye ukudla. Futhi akukwenzi ngempela umehluko ohlelweni lwakho lokugaya noma ngabe "okunye ukudla" kuxubene nekhofi ngokwayo, noma kusetshenziswe ngokuhlukile ngeforoka noma spoon. Hlala ukhumbula ukuthi ukulayisha ikhobe yakho ikhofi nge ukhilimu, ushukela, isiraphu noma ukhilimu ohlutshiwe kungaphezu kokukhansela noma yikuphi ukuzuzisa ongase uthole kuwo, njengokudla okunye okungalungile ukudla okuyokwenza.
Izwi elivela
Ngokuvamile, ukusakazeka okukhathazeka abantu abaningi mayelana nemiphumela engase ibe yinkinga yekhofi enhliziyweni ayisekelwe yizifundo zamuva zesayensi. Kubonakala sengathi, iningi labantu, ukuphuza ikhofi ngokulinganisela akulimazi impilo yomzimba, futhi kwezinye izimo kungase kube nzuzo.
Njengakho konke okunye, ukulinganisela kuyisihluthulelo. Kubantu abaningi, Nokho, eyodwa kuya ezine izindebe zekhofi ngosuku libonakala liphephile impilo yenhliziyo.
