I-Coffee May Iqukethe Ama-carcinogens, Kodwa Ingabe Abeka Ingozi Emdlalweni?
Uma ikhofi noma itiye kuboniswa ukwandisa ingozi ye- leukemia, umdlavuza wamangqamuzana egazi elimhlophe , lokhu kungaba yizindaba ezingamukeleki kubantu abaningi emhlabeni jikelele. E-United States, ikhofi iyingxenye yesibili kuphela yamanzi njengesiphuzo esisetshenziswa kakhulu kunazo zonke, futhi ngumthombo omkhulu we-caffeine phakathi kwabantu abadala. Ngakho-ke, ukugxila kukhofi lapha, kodwa abathandi betiyi kufanele baqiniseke ukuthi ucwaningo lubheka kokubili ikhofi kanye netiye mayelana nobungozi be-leukemia.
Lapho Inhlanhla Yemvelo Engenayo Impilo
Ake siqale ngokuxosha inkolelo-ze: ngoba nje ikhofi ngumkhiqizo wemvelo ovela emhlabeni, akusho ukuthi awunengozi. I-Hemlock iyimvelo. I-Radon iyi-gesi yemvelo ngokuphelele, kodwa ingabangela amacala amaningi emdlavuza wamaphaphu minyaka yonke.
Ezinye zezinto ezibonakala sengathi zingenacala kule nkampani ye-American Cancer Society "uhlu lwabantu abaziwayo" zihlanganisa lokhu okulandelayo:
- isiphuzo sokuphuza utshwala
- isrogen-progestogen therapy (ehlangene) *
- uthuli lwesikhumba
- inyama, lapho kusetshenzwa
- inhlanzi, ngokukhethekile uma isetshenziswe ngesitayela seChina
> * Kungase futhi kube nomthelela wokuvikela umdlavuza ku-endometrium ne-ovary, noma kunjalo.
Uma noma iyiphi yalezi zinto iyingxenye yokuphila kwakho, khumbula ukuthi ingozi enkulu evela ku-carcinogen eyaziwa kubalulekile ukukhumbula. Okubalulekile ukuthi ukwazi ukuthi ukuchayeka kunanoma iyiphi i-carcinogen enikeziwe kuyandisa ingozi yomdlavuza, ngaphezu kokwazi nje ukuthi i-compound inamandla okwandisa ingozi.
Esinye isici okufanele ucatshangelwe ukuthi, kukho indebe yakho ejwayelekile yekhofi, kunezinto eziningi kakhulu kune-caffeine, iphunga elimnandi nelinambitheka okumelana nazo. Isiphuzo esiyinkimbinkimbi, ikhofi ngempela iqukethe amakhemikhali amaningi asebenzayo, ngokusho kombiko oshicilelwe yamuva ku-"Journal of the American College of Cardiology." Lo mbiko wachaza ukuthi ukusetshenziswa kwekhofi kungase kuhlotshaniswe nenengozi enciphise yohlobo lwe-2 isifo sikashukela kanye nomfutho wegazi ophakeme, kanye nezinye izimo ezihlobene nengozi yempilo njengokunganama nokucindezeleka, nakuba lezi zinzuzo azizange ziboniswe.
Ngakho-ke, ikhofi iyasebenza kakhulu, futhi ezinye zalezi zenzo zingase zingabi nzuzo. Ngaphezu kwalokho, noma ngabe ubhontshisi bekhofi embusweni wabo wemvelo awunabo ama-carcinogens womuntu, bekuyohlale kukhona amathuba okuthiwa ama-carcinogens atholakale ngesikhathi esithile kulezi zinyathelo eziningi ezihamba phambili ukusuka endleleni yokulima kuya ekomelweni lomthengi:
- ukutshala nokukhula
- ukukhetha nokucubungula
- ukupakisha, ukugcina, ukuhweba, ukuthumela, ukungenisa
- ukugaya, ukugaya nokuphuza
Kusuka ku-Shrub kuya eCafé
Kwenzekani ngaphambi kokuthi igama lakho libizwe futhi i-barista ikhiqiza i-mocha yakho emuva kwesikhathi? Inkomishi yekhofi esiphuzayo namhlanje itholakala enzalweni yeCofeea arabica kanye / noma uCofeea canephora, ngemuva kokucutshungulwa nokugcoba . Lezi zitshalo zitshalo zikhula zibe izihlahla noma izihlahla ezincane izithelo noma imbewu eziyimpahla ebalulekile yokuthekelisa e-Central naseNingizimu Melika, eCaribbean nase-Afrika.
Lezi zitshalo ezinhle zingashintsha, noma kunjalo. Ezinye zezinhlobo zakudala zekhofi-kufana nezitshalo ze-tomato ze-heirloom-zivame ukungena ezifweni ezinkulu zekhofi; lapho izitshalo ziphilile, zikhiqiza imbewu ephezulu. Ngenxa yokwanda okukhulu kwezifo, izinhlelo zokuzalanisa ziphishekela ukuhlanganisa izinhlobo ezintsha zezakhi zofuzo, noma ama-cultivars, ngokunciphisa ukugula kwesifo kanye nekhwalithi enhle yezitshalo.
Ngamafuphi, ukwakhiwa kwamakhemikhali ekhofi namuhla, kufaka phakathi ama-carcinogens, okungenzeka kungabi yi-chemical composition of coffee kusasa.
Ukubunjwa kwemvelo yendaba yezitshalo kuwukuqala nje, kodwa. Ngemuva kokukhula nokuvuna, kunezindlela ezahlukene zokucubungula ezisetshenziswa embonini:
- Ekusetshenzisweni okumile , noma ekusetshenzisweni kwemvelo, izithelo ezivuthiwe zekhofi zivunwa futhi zanda phezu komhlaba njengamapayipi ensimbi noma umhlaba opakanyelwe ukuma. Lapho bahlala izinsuku ezingu-18 kuya ku-24. Uma sewomile, isithelo sesithelo esonakele sisuswe ukukhiqiza okubizwa ngokuthi ikhofi yesikhumba; lo mkhiqizo ugcinwa futhi kamuva uphonyiwe ukuze ususe ungqimba ongaphandle, okwenza ikhofi eluhlaza. Ikhofi yamasaka kanye nembewu yamakhofi eluhlaza igcinwa kwisitoreji esomile ukuze unciphise umsebenzi we-microbial ngaphambi kokuthekelisa nokugcoba.
- Emanzi ukucubungula izithelo kanye ne-pulp zikhishwa kude nembewu kusukela ekuhambeni, ngezingqimba ezincane ezihlanganisa imbewu. Imbewu ivunyelwe ukuvotela emahoreni angu-24 kuya kwangu-72 emanzini emazingeni okushisa amancane. Ama-microorganisms avela ezitshalweni, imbewu, abaphathi, amanzi, kanye nokusebenza kwemishini kungabangela ukuthi kube nokulingana kwemikhiqizo yezinhlamvu ezincane , futhi kube nakho okungathinta ikhwalithi yekhofi.
Ubhontshisi obunamanzi bavame ukhiqiza indebe yekhofi enomsoco enomzimba omncane, ngokusho kombiko kaVaughan nabasebenza nabo esanda kushicilelwa "ku-Applied and Environmental Microbiology." Lo mbiko uthi inqwaba yezinhlobo ezingu-215 ze-fungi kanye no-106 Izinhlobo ze-bacteria zitholakale zihlangene nekhofi izithelo kanye nezicubu zezithombo.
Kuye nge-microbes ezihilelekile, ngezinye izikhathi into ebizwa nge-ochratoxin A (OTA) ingahle ingcolise ikhofi. Zombili izinhlobo ze-Aspergillus ne-Penicillium ziphakathi kwalezo zifungi ezikwazi ukukhiqiza i-OTA, ehlangene kaningi futhi ibonakala iyinto ejwayelekile ekukhiqizweni kwekhofi, kusukela ezithelo kuya ekutheni. I-International Agency for Research on Cancer (i-IARC) ihlukanise i-OTA njenge-carcinogen yomuntu engenzeka.
Ingozi Ye-Leukemia Evela Kukhofi Nengqikithi: Isifundo Se-Italy
Ngakho-ke, lapho uphenyo uStefano Parodi kanye nosebenza nabo bethola ukuthi inhlangano phakathi kwekhofi yokudla ne-leukemia yayingakaziwa, baqala ukutadisha ukuze bafunde kabanzi. Babenesithakazelo ekusebenziseni itiye elimnyama njalo nanoma yikuphi ukuhlangana nomngciphe we-leukemia.
Leli qembu lisetshenziselwa idatha evela kubantu abaningi e-Italy, izwe elinomshini ophezulu wekhofi kanye nokusetshenziswa okuphansi kweti elihlaza. Abahlanganyeli abavela ezifundeni ezingu-11 zase-Italy babuzwa, kuhlanganise neziguli zokulawula ezingu-1 771 nabantu abangu-651 abane-leukemia. Izinhlangano eziphakathi kwe-acute myeloid leukemia (AML), i-lymphoid leukemia, i-CML), i-lymphoid leukemia engapheli, nokusetshenziswa kwekhofi kanye netiye kwahlolwa. Leli qembu lihlelelwe ezinye izinto ezingathonya ingozi yegazi, njengokulingana ngokobulili, ubudala, indawo yokuhlala, ukubhema, izinga lemfundo, ukwelashwa kwangaphambili kwamakhemikhali, ukuphuza utshwala, nezinye izinto ezibandakanya ukushiswa kwemishanguzo kanye nezibulala-zinambuzane.
Imiphumela: Ayikho isixhumanisi esibonakalayo ku-Leukemia
Lokhu kwakuyi-retrospective case-control study, okusho ukuthi ungathola inhlangano noma isixhumanisi, kodwa awukwazi ukusho ngokuqinisekile mayelana nemiphumela nomphumela. Lokho kusho ukuthi imiphumela evela kulolu cwaningo yayivuselela futhi abathandi bekhofi kanye nabaphuzi betiyo abamnyama, ngokufanayo.
Ayikho inhlangano ebonwayo phakathi kokusetshenziswa kwekhofi njalo nanoma yiluphi uhlobo lwe-leukemia. Eqinisweni, leli qembu labika umphumela omncane wokuzivikela wetiyi ngokuhambisana nama- myeloid malignancies (AML kanye no-CML), okwakubonakala ku-AML. Noma kunjalo, akukho buhlobo obucacile bokuphendula umthamo obutholiwe.
Izwi elivela
Ngaphambi kwalolu cwaningo, bekukhona imibiko emincane ezinkingeni ezincane ze-leukemia phakathi kwabathengi bekhofi abavamile. Ucwaningo lwamanje alutholanga ukunciphisa ingozi, kodwa ngakolunye uhlangothi, alubonanga noma iyiphi ingozi eyengeziwe.
Yinto Eyodwa
Izinzuzo eziningi ezivela ekusetshenzisweni kwekhofi ejwayelekile ziye zahlongozwa futhi zibonakala sengathi zingabonakali ngokucacile. Enye yezinzuzo ezivame ukuvezwa yiyona indima yekhofi ekuvimbeleni umdlavuza wesibindi. Njengezinto eziningi uma kuziwa ekudleni nasekusetshenzisweni kokudla, ukufaneleka kwekhofi ukusetshenziswa njalo kungaba umuntu ngamunye.
Isibonelo, uma uhlushwa isifo senhliziyo noma i-acid reflux ekhushulwa ikhofi, noma mhlawumbe uma i-caffeine ithumela ingcindezi yakho yegazi phezulu, noma mhlawumbe ubonakala unengqondo enhle isingoma esingajwayelekile esilethwe ikhofi nokucindezeleka, umthamo wansuku zonke I-java kungenzeka ingabi yinto enhle kakhulu kuwe. Ukudla ngokweqile kwekhofi kuhlanganiswe nezinkinga ezihlukahlukene, ukungasho ukulala okuncane. Futhi, ngokombono wesifo esibi, kunomunye ubufakazi obonisa ukuthi ukusetshenziswa okuphezulu, okungaphezulu kuka-6.5 izinkomishi ngosuku, kungandisa ukwanda komdlavuza wesisu.
Ngakolunye uhlangothi, uma uke waba ngumthengi wekhofi njalo iminyaka futhi uphumelela ekulungiseni kwakho ekuseni, ngokulinganisela, kungase kube nezinzuzo okumele zibe khona-futhi abukho ubufakazi bokuthi ikhofi yandisa ingozi ye-leukemia. Ukulinganisela kuyisihluthulelo, futhi udinga ukulandela iseluleko sikadokotela wakho mayelana nanoma yiziphi izimo zempilo ongase ube nazo.
Futhi, ngokombono wezempilo wenhliziyo nenengozi yomzimba, uma usebenzisa ukhilimu noshukela, ulula futhi ubumnandi uthatha ikhofi yakho, ikakhulukazi izingozi ezingase zibe khona zomkhuba wakho wekhofi zingase zenze noma yiziphi izinzuzo ezikhona.
