Ikofu sisiselo esineenkulungwane zakudala. Ubumnyama bayo kunye ne-exoticism yayo evela kwimbewu engaqhelekanga yavuselela umdla wehlabathi lonke. Xa iivenkile zekofu zaqalisa ukuvela eYurophu, abanye bathi sisiselo esinomtsalane esinokusenza sibe ngamakhoboka okungcakaza. Waphathwa njengeziyobisi. Kwaye ngaphandle kokuthandwa kwayo, kwiminyaka yee-70 kunye no-80, ikofu yayisajongwa ngokukrokra "njengento eyingozi". Olu loyiko luvela kuphando oludibanisa neengxaki zentliziyo, nangona ezinye izinto ezifana nokutyeba, uxinzelelo lwegazi oluphezulu, okanye ukutshaya aziqwalaselwanga kwezo zifundo.
Ngethamsanqa, isayensi ihambele phambili kakhulu kwaye umbono esinawo ngoku wekofu wahluke ngokupheleleyo. Esi siselo, ngokwezifundo zamva nje, sinokubonelela ngeenzuzo ezininzi zempilo kwaye sinokukhuthaza ubomi obude.
Namhlanje siza kuthetha ngokubanzi malunga neenzuzo ezi-5 ezilungileyo eziziswa yikofu. Kuyathakazelisa, ngakumbi ukuba unothando njengam kwaye ufuna ukwazi ukuba kulunge kangakanani na emzimbeni wakho. Nangona kufuneka kukhunjulwe ukuba konke ukuxhatshazwa okanye ukugqithisa kubi.
Ikofu inokuba nempilo yentliziyo yakho
En uphononongo lwezifundo ezingama-36, izazinzulu zifumene ulungelelwaniso phakathi kokusetyenziswa kwekhofi kunye nokunciphisa umngcipheko wesifo senhliziyo, kunye nalabo basela iikomityi ezintathu ukuya ezintlanu ngosuku abanomngcipheko ophantsi. Kule meko, ukusetyenziswa ngokugqithiseleyo kwekhofi Ayizange idibaniswe nomngcipheko omkhulu wokubandezeleka nasiphi na isifo senhliziyo.
Inokunceda ukuthintela a ukubetha, ngokukodwa. Kubantu abasela ikofu rhoqo (abo basela ubuncinci ikomityi enye ngosuku) kunokuqatshelwa ukuba banomngcipheko ophantsi wama-20% wokubandezeleka. istroke xa kuthelekiswa nabo bafane basele ikofu.
Ikofu ikwasikhusela kwimiba yomngcipheko womntu ngamnye kwizifo ezithile zentliziyo. Ukusetyenziswa kwayo kuye kwadityaniswa ne-a HDL ephezulu ("elungileyo") kunye ne-LDL ephantsi ("embi") i-cholesterol, kunye nomngcipheko ophantsi we isifo metabolic y uhlobo II lweswekile.
Inokusinceda siphile ixesha elide
Kungekudala, ndafunda ukuba abasela ikofu banokuphila ixesha elide. Uninzi lwethu luyazi ukuba esi siselo sinxulunyaniswa nomngcipheko ophantsi wokufa, kodwa ndifumene iziphumo ezitsha kolu phononongo lunomdla kakhulu.
Uphando, ipapashwe kwi-JAMA Internal Medicine, yafumanisa ukuba ukusela ikofu kudibaniswa nobomi obude kunye nomngcipheko ophantsi wokufa, ngokukodwa kwisifo senhliziyo kunye nomhlaza (ezimbini kwezintlanu ezibangela ukufa).
Abaphandi bafunde idatha yedemografi kunye nempilo kubantu abangaphezu kwe-498.000 yaseBrithani, kubandakanywa nolwazi malunga nokusetyenziswa kwekofu kunye nokuba ngaba babeneentlobo zemfuza ezichaphazela i-caffeine metabolism.
Kwiminyaka elishumi kamva, abaphandi bafumanisa ukuba abantu abasela ikomityi enye yekofu ngosuku babenomngcipheko ophantsi we-6% wokufa kunabo basela ngaphantsi kweso sixa. Kwaye, abo batya iikomityi ezisibhozo okanye ngaphezulu ngosuku babenomngcipheko ophantsi we-14%.
Olu phando lwalusekwe kuphela kuqwalaselo, ngoko akubonakali ukuba ukusetyenziswa kwekofu kubangele umngcipheko ophantsi wokufa; ibonisa kuphela ubudlelwane phakathi kokusetyenziswa kunye nobomi obude.
Olu phando alulokuqala ukuba nomdla kwimpembelelo yekofu kumngcipheko wokufa. Ngo-2017, Isifundo yenza uhlolisiso kwiqela elahlukahlukeneyo eHawaii naseLos Angeles. Bafumene ikhonkco phakathi kwekofu yemihla ngemihla kunye nokunciphisa umngcipheko wokufa ngokubanzi, kunye nokufa okuvela:
- Isifo sentliziyo
- Umhlaza
- Ukubetha kwengqondo
- Diabetes
- isifo sezintso
- Isifo sokuphefumla
Xa kuthelekiswa nabantu abangazange basele ikofu okanye abangafane bayisele ikofu, abo basela ikomityi enye ngemini baye bafumanisa ukuba I-12% ngaphantsi komngcipheko obulalayo. Kwaye abo basela iikomityi ezintathu zekofu yonke imihla babene 18% ngaphantsi yamathuba okufa. Iziphumo zazifana kuzo zombini i-caffeinated kunye nekofu ye-decaf, kwaye ubudala, isini, okanye ukusetyenziswa kotywala kwakungakhathali.
I-Antioxidants kunye ne-anti-inflammatory
Nangona zonke ezi zifundo zingachazi ngokucacileyo ukuba kutheni ikofu inefuthe elihle kangaka kwimpilo, sinokuhlalutya ezinye izinto ezinokusinika ingcamango encinane. Umzekelo, eyona nxalenye inkulu yi polyphenols, eziziikhompawundi ezisebenza njenge-antioxidants. Kwakhona, kubonakala ngathi ikofu nayo anti-ukudumba. Ke apha sinezizathu ezibini zokuba kubonakala ngathi kusempilweni. Ekugqibeleni, izifo ezininzi zanamhlanje zibangelwa umonakalo we-oxidative kunye nokuvuvukala.
Inokunciphisa umngcipheko womhlaza
Njengoko besesitshilo ngaphambili, ikofu inamakhulukhulu izinto eziphilayo ezisebenzayo kunye nezikhuselayo, kubandakanywa i-flavonoids, i-lignans kunye nezinye iipolyphenols; evimbela i-metastasis, ilawula iijene ezibandakanyekayo ekulungiseni i-DNA, i-block umonakalo weseli kunye nokunciphisa ukuvuvukala. zikhona amawaka ezifundo abaye banomdla kubudlelwane phakathi kwekofu kunye neentlobo ezahlukeneyo zomhlaza.
Mama
Ukusetyenziswa kwekofu ephezulu kuye kwadibaniswa nomngcipheko ophantsi we umhlaza webele wasemva kokumenopausal. Kwakukho Isifundo ebonisa ukuba ukusela ikofu kunciphisa umngcipheko womhlaza webele ngama-57%, nangona kwakungekho mpembelelo kumngcipheko wokuphuhlisa i-estrogen receptor-positive tumor.
Idlala lengqula
En uhlalutyo lwemeta Kwizifundo ezili-13, esi siselo sayanyaniswa nomngcipheko ophantsi womhlaza wedlala lesinyi.
Isibindi
Ngo-2005 kwaqhutywa Isifundo apho amadoda nabasetyhini ababesela ikofu rhoqo babenomngcipheko ophantsi we-hepatocellular carcinoma kunabo babengafane basele ikofu. Kwakhona, kunyaka ophelileyo, abaphandi bafumanisa ukuba ikomityi nje ngemini inokunciphisa umngcipheko we-hepatocellular carcinoma kwi20%.
uyasikhusela kudandatheko
Kwiminyaka embalwa edlulileyo yenziwa Isifundo uphononongo lwabasetyhini abangaphezu kwe-50.000, olufumene ukuba umngcipheko wokudakumba uyancipha ngokusetyenziswa kwekhofi (i-caffeinated). I-Decaf ayizange ibe nonxulumano oluqinileyo nokuncipha kokudakumba. Abasetyhini abasela ngaphezulu kweekomityi ezi-4 ngosuku babenokuncipha okukhulu komngcipheko. Kwi olunye uphando, abasela ikofu (iikomityi ezimbini okanye ngaphezulu ngosuku) bafunyenwe bene I-32% yezinga eliphantsi lokudakumba kunabo bangaseliyo esi siselo.
Inokuphelisa isifo sikaParkinson
Ukutya okuphezulu kwekofu (enecaffeine) kuye kwadityaniswa nokwehla okubonakalayo kwi-Parkinson's. abambalwa Izifundo nto leyo ebeka umngcipheko wokuncipha phakathi kwama-32 nama-60%. Inzululwazi ikholelwa ukuba kungenxa yokuba ikofu inyusa ukuhamba kwamathumbu, ngaloo ndlela idala indawo yamathumbu echasene ne-pathology ehambelana nayo. Isifo sikaParkinson.
Amanyathelo okhuseleko kufuneka uwathathe xa usebenzisa
Sizibonile zonke izibonelelo ezingcono esinokuzifumana kwikofu (enecaffeine, ngakumbi). Nangona kunjalo, kufuneka sithathe amanyathelo okhuseleko, ngokuxhomekeke kwiimeko zethu zokusebenzisa kunye nokunyamezela.
Unokungasebenzi kakuhle kwe-axis ye-HPA
Ukuba i-hypothalamic-pituitary-adrenal (HPA) axis yakho ayisebenzi, ukusela esi siselo kunokuba ngumbono ombi, kuba kunokubangela amajita amaninzi. Wazi njani ukuba kukho uhlobo oluthile lokungasebenzi kakuhle?
- Uziva udiniwe kusasa okanye une-energy spikes emva kwemini.
- Awulali kakuhle: unengxaki yokulala okanye unengxaki yokuphuthelwa.
- Kuthatha ixesha elide ukuchacha kuqeqesho.
- Ukusela ikofu kukwenza uzive udiniwe.
Awuyisebenzisi i-caffeine ngokukhawuleza
I-caffeine i-metabolized yi-enzyme esinayo esibindi kwaye ifakwe kwi-CYP1A2 gene. Phantse i-50% yabemi inomahluko kule gene, ebangela ukucotha kwe-caffeine.
Ukuba unobunzima bokuphula i-caffeine kwaye ihlala kumjikelezo wakho ixesha elide, inokudityaniswa:
- Ukonyuka komngcipheko wesifo senhliziyo
- Ukonyuka komngcipheko woxinzelelo lwegazi
- Ukuphazamiseka kokuzila ukutya kweglucose
- umgangatho wobuthongo ombi
Ukhulelwe
Ukusebenzisa isixa esikhulu sesi siselo kubonakala kwandisa umngcipheko wengozi kwabasetyhini, okubangela ukuzalwa kwangaphambi kwexesha okanye ukuzalwa kwabantwana abancinci. Kuyacetyiswa ukuba ukhethe i-decaffeinated ukuphepha olu hlobo lomngcipheko.
