I-Grass-Fed vs. Beef-Fed Beef - Uyini Umehluko?

-Delile

• Umehluko phakathi kwezinkomo ezotshaniwe nezisanhlamvu
• Umehluko ekwakhiweni kwamafutha acid
• Inyama yenkomo edliwe ngotshani inomsoco kakhulu
• Ingabe inyama yenkomo eyondliwe ngotshani iyazifanela izindleko ezingeziwe nokuphazamiseka okungahle kube khona?
• Okubalulekile

Indlela izinkomo ezondliwa ngayo ingaba nomthelela omkhulu ekwakhiweni komsoco wenkomo yazo.

Ngenkathi izinkomo namuhla zivame ukondliwa okusanhlamvu, izilwane abantu abazidlayo kuyo yonke imvelo zazulazula mahhala futhi zidla utshani.

Ucwaningo oluningi lukhombisile ukuthi umsoco wenkomo ungahluka ngokuya ngokuthi izinkomo zidlani.

Lapho inyama yenkomo ikhiqizwa ngobuningi, njengase-United States, izinkomo zivame ukondliwa okusanhlamvu. Kodwa-ke, inyama yenkomo ekhuliswe ngotshani ivamile kwamanye amazwe amaningi, njenge-Australia.

Ungase uzibuze ukuthi indlela izinkomo ezondliwa ngayo iyawenza yini umehluko empilweni yakho.

Lo mbhalo ubheka ubufakazi bokunquma umehluko phakathi kwenkomo yenkomo edla utshani nenhlamvu.

Umehluko phakathi kwezinkomo ezotshaniwe nezisanhlamvu

E-United States, izinkomo eziningi ziqala ukuphila impilo efanayo.

Amathole azalwa ekuqaleni kwentwasahlobo, aphuze ubisi konina, bese evunyelwa ukuzulazula mahhala futhi adle utshani noma ezinye izitshalo ezidliwayo ezizithola endaweni yazo.

Lokhu kuqhubeka cishe izinyanga eziyi-7-9. Ngemuva kwalokho, izinkomo eziningi ezikhuliswe ngokujwayelekile zihanjiselwa izindawo zokuhlala.

Izindawo ezinkulu zokuphakela zibizwa ngokuthi imisebenzi yokugxilisa ukudla kwezilwane (CAFOs). Lapho, izinkomo zigcinwa ezibayeni, ngokuvamile zinendawo encane.

Zikhulupheliswa ngokushesha ngokudla okususelwa okusanhlamvu okuvame ukwenziwa ngesisekelo soya noma ummbila. Imvamisa, ukudla kwabo kubuye kufakwe ngotshani obomile obuncane.

Izinkomo zihlala kulezi zindawo zokudla izinyanga ezimbalwa ngaphambi kokuba zilethwe esilaheni.

Vele, akulula kangako. Izindlela zokudla ezahlukahlukene ziyinkimbinkimbi futhi ziyahlukahluka.

Isibonelo, inyama yenkomo eyondliwe ngotshani e-Australia ingahle ingaqhathaniseki ngqo nemikhiqizo yase-US, futhi inyama yenkomo eyondliwe ngotshani ayikhuliswa ngempela emadlelweni. Akuzona zonke izinkomo ezondliwe ngotshani ezingaklaba ngaphandle.

Eqinisweni, igama elithi utshani obudliwayo alichaziwe kahle.

Lokho kusho ukuthi, izinkomo ezondliwe ngotshani zidla (ikakhulukazi) utshani, ngenkathi izinkomo ezondliwe okusanhlamvu zidla (ikakhulukazi) ukudla okungekhona okwemvelo okususelwa kummbila nosoya engxenyeni yokugcina yempilo yabo.

Ukukhulisa ukukhula, izinkomo zivame ukunikezwa imishanguzo, njengama-antibiotic nama-hormone okukhula.

Kusukela ngoJanuwari 1, 2017, i-Food and Drug Administration (i-FDA) yadlulisa umthetho omusha owaziwa nge-Veterinary Feed Directive.

Ngokwalo mthetho, ama-antibiotic athathwa njengabalulekile emithini yabantu adinga ukwenziwa ngaphansi kokubhekwa ngudokotela wezilwane onelayisense futhi angeke asetshenziselwe ukukhuthaza ukukhula ().

Izinkomo eziningi ziqala emadlelweni, ziphuze ubisi futhi zidle notshani. Kodwa-ke, izinkomo ezikhuliswe ngokujwayelekile zivame ukuhanjiswa ziye ezindaweni zokuphakelwa futhi zondliwe ikakhulukazi okuphakelwa okusanhlamvu.

Umehluko ekwakhiweni kwamafutha acid

"Uyikho okudlayo" kusebenza ezinkomeni, futhi.

Okudliwa yinkomo kungakuthinta kakhulu ukwakheka komsoco wenkomo yayo. Lokhu kubonakala ikakhulukazi uma kukhulunywa ngokwakhiwa kwamafutha acid.

Inkomo yenkomo edliwe ngotshani imvamisa iqukethe amafutha angaphansi kwesamba kunenkomo eyondliwe okusanhlamvu, okusho ukuthi igramu yegremu, inyama yenkomo ekhuliswe ngotshani iqukethe ama-calories ambalwa ().

Kodwa-ke, ukwakheka kwamafutha acid kuhlukile:

• Amafutha e-Monounsaturated. Inkomo yenkomo efuthwe ngotshani iqukethe amanoni amancane kakhulu e-monounsaturated kunenkomo eyondliwe okusanhlamvu ().
• Amafutha we-Omega-6 polyunsaturated. Inkomo yenkomo eyondliwe notshani iqukethe inani elifanayo kakhulu le-omega-6 fatty acids.
• I-Omega-3s. Yilapho ukondla okwenziwa ngotshani kwenza umehluko omkhulu, kuqukethe ama-omega-3 () aphindwe kahlanu.
• I-linoleic acid ehlanganisiwe (CLA). Inkomo yenkomo efuthwe ngotshani iqukethe cishe i-CLA ephindwe kabili kunenkomo eyondliwe okusanhlamvu. Le fatty acid ihlotshaniswa nezinzuzo ezimbalwa zezempilo (,).

Ngamafuphi, kunomehluko ophawulekayo ekwakhiweni kanye nenani lamafutha enkomo yenkomo yotshani- kanye nenhlamvu.

Ngaphezu kwalokho, ukuzalana nokusikwa kwenyama kuthinta kakhulu ukwakheka kwamafutha enkomo ().

Inyama yenkomo eyondliwe ngotshani ingaqukatha amanoni angaphansi kwesilinganiso kunenkomo eyondliwe okusanhlamvu, kepha ama-omega-3 fatty acids amaningi kanye ne-CLA, zombili ezixhumene nezinzuzo zezempilo.

Inyama yenkomo edliwe ngotshani inomsoco kakhulu

Kokubili okwenkomo okusanhlamvu okusanhlamvu notshani kuyimithombo egxile kakhulu kwezakhamzimba.

Inkabi ilayishwe uvithamini B12, B3, no-B6. Ibuye ibe nensimbi etholakala nge-bioavailable, i-selenium ne-zinc. Eqinisweni, inyama iqukethe cishe zonke izakhi ozidingayo ukuze uphile ().

Futhi iqukethe amaprotheni wekhwalithi ephezulu kanye nezakhamzimba ezahlukahlukene ezingaziwa kangako, ezinjenge-creatine ne-carnosine, ezibaluleke kakhulu emisipheni nasebuchosheni bakho.

Kodwa noma umehluko ungemkhulu, inyama yenkomo eyondliwa ngotshani ngokuvamile iqukethe amanani aphezulu ezakhamzimba ezithile.

Uma kuqhathaniswa nenyama yenkomo eyondliwe okusanhlamvu, okwenziwe ngotshani kuphakeme kakhulu kulawa mavithamini alandelayo:

• Uvithamini A. Inyama yenkomo eyondliwe ngotshani iqukethe abangaphambi kwe-carotenoid ku-vitamin A, njenge-beta carotene.
• Uvithamini E. Le antioxidant ihlala ezingxenyeni zeseli lakho futhi iyazivikela ekuxutheni ().

Inkomo yenkomo edliwe ngotshani nayo ivamise ukunotha kwamanye ama-antioxidants (,).

Inyama yenkomo edla okusanhlamvu ejwayelekile inomsoco kakhulu, kodwa inyama yenkomo edla utshani iqukethe ama-carotenoid amaningi, i-vitamin E, namanye ama-antioxidants.

Ingabe inyama yenkomo eyondliwe ngotshani iyazifanela izindleko ezingeziwe nokuphazamiseka okungahle kube khona?

Kubalulekile ukukhumbula ukuthi ngisho nenyama yenkomo ejwayelekile, eyondliwe okusanhlamvu inomsoco kakhulu.

Uma nje ungadli inyama yakho yenkomo, engaholela ekwakhiweni kwamakhemikhali ayingozi, kungukudla okunomsoco okungaba yingxenye yokudla okunempilo.

E-United States, inyama yenkomo eyondliwe ngotshani ingabiza kakhulu, futhi ingahle ingazidingi izindleko ezengeziwe zabanye abantu.

Ngokuya ngokuthi uhlala kuphi, kungahle kube nzima ukuphinde uthenge inyama yenkomo eyondliwe ngotshani.

Ngenkathi abanye abantu bengahlala eduze nemakethe yomlimi noma isitolo sokudla okuphelele, abanye bangadinga ukushayela amabanga amade ukuthola inyama yenkomo enotshani.

Kungaba nokwehluka okucashile kokunambitheka. Inkomo yenkomo edliwe ngotshwala ivame ukuncika futhi ingahle ibe nokuthungwa okwehlukile.

Yize inyama yenkomo eyondliwe ngotshani iqukethe inani eliphakeme lezakhamzimba ezithile, njengamanje abukho ubufakazi obuqand 'ikhanda bokuthi iphilile kakhulu kunenkomo edliwe okusanhlamvu esimeni sokudla okulinganiselayo.

Ekugcineni, ukukhetha kuya ngezintandokazi zakho kanye nemibono yakho. Abanye abantu bakhetha ukudliwa ngotshani, kanti abanye bakhetha ukusuthiswa okusanhlamvu. Zama zombili bese ubona ukuthi iyiphi oyithandayo kangcono.

Yize inyama yenkomo eyondliwe ngotshani ihlukene ngezakhi eziningana zomzimba, imiphumela yayo empilweni yakho ingafana.

Okubalulekile

Phezu kwazo zonke izingxabano emkhakheni wezokudla, abantu abaningi bayavuma ukuthi into ebaluleke kakhulu ukudla ukudla kwangempela.

Abanye abantu bathanda ukuthatha lo mbono igxathu eliya phambili futhi badle kuphela ukudla kwangempela okudla ukudla kwangempela. Ngemuva kwakho konke, utshani namakhambi kungukudla okungokwemvelo kwezinkomo ukwedlula ummbila kanye nesoya.

Ekupheleni kosuku, ukukhetha kuya ngezintandokazi zakho namanani akho.
