• Okubalulekile

Ikhofi esheshayo ithandwa kakhulu ezindaweni eziningi zomhlaba.

Kungaba ne-akhawunti engaphezulu kwe-50% yakho konke ukusetshenziswa kwekhofi kwamanye amazwe.

Ikhofi esheshayo nayo iyashesha, ishibhile, futhi kulula ukuyenza kunekhofi ejwayelekile.

Ungahle wazi ukuthi ukuphuza ikhofi elijwayelekile kuxhunyaniswe nezinzuzo eziningi zezempilo kepha uzibuze ukuthi izinzuzo ezifanayo ziyasebenza nakukhofi osheshayo (,,,).

Lo mbhalo uchaza konke odinga ukukwazi mayelana nekhofi elisheshayo nemiphumela yalo yezempilo.

Yini ikhofi esheshayo?

Ikhofi elisheshayo luhlobo lwekhofi elenziwe ngohlobo lwekhofi elomisiwe.

Ngokufanayo nendlela ikhofi ejwayelekile elenziwa ngayo, okukhishwayo kwenziwa ngokuphuza ubhontshisi wekhofi womhlabathi, yize kugxilwe kakhulu.

Ngemuva kokupheka, amanzi ayasuswa kokukhishwayo ukwenza izingcezu ezomile noma impuphu, zombili ezincibilikayo uma zengezwa emanzini.

Kunezindlela ezimbili eziyinhloko zokwenza ikhofi elisheshayo:

• Ukomisa isifutho. Ikhofi likhishwa emoyeni oshisayo, owomisa ngokushesha amaconsi bese uwaguqula abe yimpuphu ecolekileyo noma izingcezu ezincane.
• Ukuqandisa. Okukhishwa ikhofi kufriziwe bese kusikwa kube izingcezu ezincane, bese zomiswa ezingeni lokushisa eliphansi ngaphansi kwezimo ze-vacuum.

Zombili lezi zindlela zigcina ikhwalithi, iphunga nokunambitheka kwekhofi.

Indlela ejwayelekile yokulungisa ikhofi esheshayo ukufaka isipuni esisodwa se-powder enkomishini yamanzi ashisayo.

Amandla ekhofi angalungiswa kalula ngokungeza i-powder engaphezulu noma encane enkomishini yakho.

Ikhofi elisheshayo lenziwa ngekhofi eliphekiwe elisuswe amanzi. Ukwenza ikhofi esheshayo, mane ufake isipuni esisodwa se-powder enkomishini yamanzi afudumele.

Ikhofi esheshayo iqukethe ama-antioxidants nezakhi zomzimba

Ikhofi ingumthombo omkhulu wama-antioxidants ekudleni kwesimanje (,,,).

Okuqukethwe kwayo okuphezulu kwe-antioxidant kukholakala ukuthi kuyimbangela yezinzuzo zayo eziningi ezihlobene nezempilo ().

Njengekhofi elijwayelekile, ikhofi elisheshayo liqukethe ama-antioxidants amaningi anamandla (,).

Ngokuya kocwaningo oluthile, ikhofi elisheshayo lingaqukatha inani eliphakeme kakhulu lama-antioxidants athile kunamanye ama-brew, ngenxa yendlela elungiswa ngayo ().

Ngaphezu kwalokho, inkomishi eyodwa ejwayelekile yekhofi esheshayo iqukethe ama-calories ayi-7 kuphela namanani amancane we-potassium, i-magnesium, ne-niacin (uvithamini B3) ().

Ikhofi esheshayo ligcwele ama-antioxidants anamandla. Ingaqukatha inani eliphakeme lama-antioxidants ezinye kunezinye izinhlobo zekhofi.

Ikhofi esheshayo iqukethe i-caffeine engaphansi kancane

I-caffeine iyisikhuthazi esisetshenziswa kakhulu emhlabeni, futhi ikhofi lingumthombo walo omkhulu wokudla ().

Kodwa-ke, ikhofi elisheshayo ngokuvamile liqukethe i-caffeine engaphansi kancane kunekhofi ejwayelekile.

Inkomishi eyodwa yekhofi esheshayo equkethe isipuni esisodwa sempuphu ingaqukatha u-30-90 mg we-caffeine, kanti inkomishi eyodwa yekhofi ejwayelekile iqukethe u-70-140 mg (,,, 17).

Njengoba ukuzwela kwe-caffeine kuyahlukahluka kumuntu ngamunye, ikhofi esheshayo ingaba yindlela engcono kulabo abadinga ukunciphisa i-caffeine ().

Ikhofi esheshayo nayo iyatholakala nge-decaf, equkethe i-caffeine encane kakhulu.

I-caffeine eningi kakhulu ingadala ukukhathazeka, iphazamise ukulala, ukungahlaliseki, isisu esicasukile, ukuthuthumela, nokushaya kwenhliziyo okusheshayo ().

Inkomishi yekhofi esheshayo equkethe isipuni esisodwa sempuphu ngokuvamile iqukethe u-30-90 mg we-caffeine, kuyilapho ikhofi ejwayelekile iqukethe u-70-140 mg inkomishi ngayinye.

Ikhofi esheshayo iqukethe i-acrylamide eningi

I-Acrylamide yikhemikhali elingaba yingozi elenzeka lapho kubhakwa ubhontshisi wekhofi ().

Leli khemikhali liphinde litholakale ezinhlotsheni eziningi zokudla, intuthu, izinto zasendlini, nemikhiqizo yokunakekelwa komuntu siqu ().

Kuyathakazelisa ukuthi ikhofi elisheshayo lingaba ne-acrylamide ephindwe kabili kunekhofi entsha, eyosiwe (,).

Ukuvezwa ngokweqile ku-acrylamide kungalimaza uhlelo lwezinzwa futhi kwandise ingozi yomdlavuza (,,).

Kodwa-ke, inani le-acrylamide ovezwe kulo ngokudla nekhofi liphansi kakhulu kunenani elikhonjisiwe ukuthi liyingozi (26,).

Ngakho-ke, ukuphuza ikhofi esheshayo akufanele kubangele ukukhathazeka maqondana nokuchayeka kwe-acrylamide.

Ikhofi elisheshayo liqukethe i-acrylamide ephindwe kabili kunekhofi ejwayelekile, kodwa leli nani lisephansi kunenani elibhekwa njengelimazayo.

Njengekhofi ejwayelekile, ikhofi esheshayo ingaba nezinzuzo eziningana zezempilo

Ukuphuza ikhofi kuye kwaxhunyaniswa nezinzuzo eziningi zezempilo.

Njengoba kunikezwe ukuthi ikhofi elisheshayo liqukethe ama-antioxidants afanayo nezakhamzimba njengekhofi elijwayelekile, kufanele linikeze imiphumela eminingi efanayo yezempilo.

Ukuphuza ikhofi esheshayo kunga:

• Thuthukisa ukusebenza kobuchopho. Okuqukethwe yi-caffeine kungathuthukisa ukusebenza kobuchopho (28).
• Thuthukisa imetabolism. I-caffeine yayo ingakhuphula umzimba futhi ikusize ushise amanoni amaningi (,,).
• Nciphisa ubungozi besifo. Ikhofi inganciphisa ubungozi bezifo ezingenayo i-neurodegenerative, njenge-Alzheimer's and Parkinson's (,,).
• Nciphisa ingozi yesifo sikashukela. Ikhofi lingasiza ekunciphiseni ubungozi bokuthola uhlobo lwesifo sikashukela sohlobo lwesibili (,,).
• Thuthukisa impilo yesibindi. Ikhofi ne-caffeine kunganciphisa ubungozi bezifo zesibindi njenge-cirrhosis nomdlavuza wesibindi (,,).
• Thuthukisa impilo yengqondo. Ikhofi lingasiza ekwehliseni ubungozi bokudangala nokuzibulala (,).
• Thuthukisa impilo ende. Ukuphuza ikhofi kungakusiza uphile isikhathi eside (,,).

Kodwa-ke, kubalulekile ukukhumbula ukuthi eziningi zalezi zifundo zazibhekwa.

Lezi zinhlobo zezifundo azikwazi ukufakazela lelo khofi imbangelaokuyingozi encishisiwe yezifo - kuphela ukuthi abantu abajwayele ukuphuza ikhofi yibo mancane amathuba ukuthuthukisa izifo.

Uma uzibuza ukuthi ungakanani ikhofi ozophuza, odlayo 3–Izinkomishi ezi-5 zekhofi esheshayo usuku ngalunye lungalunga. Izifundo zivame ukuxhumanisa leli nani nokuncishiswa kwengozi ephezulu kakhulu (,).

Ikhofi elisheshayo linikeza izinzuzo eziningi zezempilo njengekhofi ejwayelekile, kufaka phakathi ingozi encishisiwe yohlobo lwesifo sikashukela sesibili nesifo sesibindi.

Okubalulekile

Ikhofi elisheshayo liyashesha, lilula, futhi alidingi umenzi wekhofi. Ibuye ibe nokuphila isikhathi eside kakhulu futhi ishibhile kunekhofi ejwayelekile.

Ngakho-ke, kungaba usizo kakhulu uma usohambweni noma usohambweni.

Ikhofi esheshayo iqukethe i-caffeine encane ne-acrylamide ethe xaxa kunekhofi ejwayelekile, kepha iqukethe ama-antioxidants afanayo amaningi.

Sekukonke, ikhofi elisheshayo liyisiphuzo esinempilo, esinama-khalori amancane esixhunyaniswe nezinzuzo zezempilo ezifanayo nezinye izinhlobo zekhofi.
