Grass-Fed vs. Ng'ombe Zodyetsedwa - Kodi Pali Kusiyana Pati?

Zamkati

• Kusiyana pakati pa udzu- ndi ng'ombe zodyetsedwa
• Kusiyana kwamafuta acid
• Ng'ombe zodyetsedwa ndi msipu ndizopatsa thanzi
• Kodi ng'ombe yodyetsedwa ndi udzu ndiyofunika mtengo wowonjezera komanso zovuta zina?
• Mfundo yofunika

Momwe ng'ombe zimadyetsedwera zimakhudza kwambiri michere ya ng'ombe zawo.

Pomwe ng'ombe masiku ano zimadyetsedwa mbewu, nyama zomwe anthu amadya nthawi yonseyi zimangoyendayenda ndikudya udzu.

Kafukufuku wochuluka wasonyeza kuti michere ya ng'ombe imatha kusiyanasiyana kutengera zomwe ng'ombe zimadya.

Kumene ng'ombe zimapangidwa kwambiri, monga ku United States, ng'ombe nthawi zambiri zimadyetsedwa. Komabe, ng'ombe yodyetsedwa ndi udzu imapezeka m'maiko ena ambiri, monga Australia.

Mutha kudabwa ngati momwe ng'ombe zimadyetsedwera zimapangitsa kusiyana kulikonse paumoyo wanu.

Nkhaniyi ikuyang'ana umboni kuti mudziwe kusiyana pakati pa ng'ombe yodyetsedwa ndi udzu.

Kusiyana pakati pa udzu- ndi ng'ombe zodyetsedwa

Ku United States, ng'ombe zambiri zimayamba kukhala ndi moyo wofanana.

Ng'ombezo zimabadwa kumayambiriro kwa nthawi yamasika, zimamwa mkaka kuchokera kwa amayi awo, kenako zimaloledwa kuyenda momasuka ndikudya udzu kapena mbewu zina zodyedwa zomwe zimapezeka m'malo awo.

Izi zikupitilira pafupifupi miyezi 7-9. Pambuyo pake, ng'ombe zambiri zomwe zimakwezedwa mozungulira zimasamutsidwa kuti zizidyera.

Malo akuluakulu odyetserako ziweto amatchedwa ntchito yodyetsa nyama (CAFOs). Kumeneko, ng'ombe zimasungidwa m'makola, nthawi zambiri opanda malo.

Amanenepetsedwa mwachangu ndimakina ozikidwa panjere omwe nthawi zambiri amapangidwa kuchokera ku soya kapena chimanga. Nthawi zambiri, chakudya chawo chimaphatikizidwanso ndi udzu wouma pang'ono.

Ng'ombezi zimakhala m'malo amenewa kwa miyezi ingapo zisanabweretsedwe kumalo ophera nyama.

Inde, sizophweka. Njira zosiyanasiyana zodyetsera ndizovuta komanso zosiyanasiyana.

Mwachitsanzo, ng'ombe zodyetsedwa ndi udzu ku Australia mwina sizingafanane mwachindunji ndi zinthu zaku US, ndipo ng'ombe yodyetsedwa ndi udzu sikuti imangodyetsedwa kumene. Si ng'ombe zonse zodyetsedwa ndi udzu zomwe zimadya panja.

M'malo mwake, mawu oti udzu wodyetsedwa sakutanthauziridwa bwino.

Izi zati, ng'ombe zodyetsedwa ndi udzu zimadya (makamaka) udzu, pomwe ng'ombe zodyetsedwa ndi tirigu zimadya (makamaka) zakudya zosakhala zachilengedwe kutengera chimanga ndi soya kumapeto kwa moyo wawo.

Kukulitsa kukula, ng'ombe nthawi zambiri zimapatsidwa mankhwala, monga maantibayotiki ndi mahomoni okula.

Kuyambira pa 1 Januware, 2017, Food and Drug Administration (FDA) idakhazikitsa malamulo atsopano otchedwa Veterinary Feed Directive.

Malinga ndi lamuloli, maantibayotiki omwe amawawona kuti ndi ofunika pamankhwala amunthu amayenera kuperekedwa moyang'aniridwa ndi veterinarian wokhala ndi chilolezo ndipo sangathe kugwiritsidwa ntchito kupititsa patsogolo kukula).

Ng'ombe zambiri zimayambira pamalo odyetserako ziweto, kumwa mkaka ndikudya udzu. Komabe, ng'ombe zomwe zidakwezedwa pamisonkhano pambuyo pake zimasamutsidwa kupita kumalo odyetserako ziweto ndipo zimangodyetsedwa makamaka chakudya chokhazikitsidwa ndi njere.

Kusiyana kwamafuta acid

"Ndiomwe mumadya" imagwiranso ntchito ku ng'ombe.

Zomwe ng'ombe imadya zimakhudza kwambiri michere ya ng'ombe yake. Izi zimawonekera makamaka pankhani yamafuta a asidi.

Ng'ombe zodyetsedwa ndi msipu nthawi zambiri zimakhala ndi mafuta ochepa kuposa ng'ombe yodyetsedwa, zomwe zikutanthauza kuti gramu ya gramu, ng'ombe yodyetsedwa ndi udzu imakhala ndi ma calories ochepa ().

Komabe, kapangidwe ka mafuta zidulo ndizosiyana:

• Monounsaturated mafuta. Ng'ombe yodyetsedwa ndi msipu imakhala ndi mafuta ochepa monounsaturated kuposa ng'ombe yodyetsedwa ndi tirigu ().
• Mafuta a Omega-6 polyunsaturated. Ng'ombe yamphongo yodyetsedwa ndi tirigu imakhala ndi omega-6 mafuta acids ambiri.
• Omega-3s. Apa ndipamene udzu wobiriwira umapanga kusiyana kwakukulu, wokhala ndi omega-3 () kasanu.
• Conjugated linoleic acid (CLA). Ng'ombe yodyetsedwa ndi msipu imakhala ndi CLA yochulukirapo kuposa ng'ombe yodyetsedwa ndi tirigu. Mafuta a asidiwa amaphatikizidwa ndi maubwino ochepa athanzi (,).

Mwachidule, pali kusiyana kwakukulu pakapangidwe kake ndi kuchuluka kwa mafuta mu udzu- ndi ng'ombe zodyetsedwa ndi tirigu.

Kuphatikiza apo, mtundu ndi kudula kwa nyama kumakhudza kwambiri mafuta omwe amapangidwa ndi ng'ombe ().

Ng'ombe yodyetsedwa ndi msipu imatha kukhala ndi mafuta ochepa kuposa ng'ombe yodyetsedwa ndi tirigu, koma omega-3 fatty acids ambiri ndi CLA, zomwe zonse zimalumikizidwa ndi maubwino azaumoyo.

Ng'ombe zodyetsedwa ndi msipu ndizopatsa thanzi

Ng'ombe zodyetsedwa ndi tirigu ndi udzu ndizomwe zimapatsa thanzi.

Ng'ombe yodzaza ndi vitamini B12, B3, ndi B6. Imakhalanso ndi chitsulo chosowa kwambiri, selenium, ndi zinc. M'malo mwake, nyama imakhala ndi michere yonse yomwe mumafunikira kuti mukhale ndi moyo ().

Mulinso mapuloteni apamwamba kwambiri komanso michere yambiri yosadziwika bwino, monga creatine ndi carnosine, zomwe ndizofunikira kwambiri minofu ndi ubongo wanu.

Koma ngakhale kusiyana kwake sikokulira, ng'ombe yodyetsedwa ndi udzu nthawi zambiri imakhala ndi michere yambiri.

Poyerekeza ndi ng'ombe yodyetsedwa ndi tirigu, udzu wodyetsedwa udzu umakhala wokwera kwambiri m'mavitamini otsatirawa:

• Vitamini A. Ng'ombe yodyetsedwa ndi msipu imakhala ndi zotengera za carotenoid za vitamini A, monga beta carotene.
• Vitamini E. Antioxidantiyi imakhala m'makhungu anu ndikuwateteza ku oxidation ().

Ng'ombe zodyetsedwa ndi udzu zimakhalanso zolemera mu ma antioxidants ena (,).

Ng'ombe yodyetsedwa yambewu yathanzi imakhala yathanzi kwambiri, koma ng'ombe yodyetsedwa ndi udzu imakhala ndi ma carotenoid ambiri, vitamini E, ndi ma antioxidants ena.

Kodi ng'ombe yodyetsedwa ndi udzu ndiyofunika mtengo wowonjezera komanso zovuta zina?

Ndikofunika kukumbukira kuti ngakhale nyama wamba yodyetsedwa ndi tirigu imakhala yathanzi kwambiri.

Malingana ngati simukugunda ng'ombe yanu, yomwe ingapangitse kuti pakhale mankhwala owopsa, ndi chakudya chopatsa thanzi chomwe chingakhale gawo la chakudya chopatsa thanzi.

Ku United States, ng'ombe yodyetsedwa ndi udzu imatha kukhala yokwera mtengo, ndipo itha kukhala yopanda mtengo kwa anthu ena.

Kutengera komwe mumakhala, zimathanso kukhala zovuta kugula ng'ombe yodyetsedwa ndi udzu.

Ngakhale kuti anthu ena amakhala pafupi ndi msika wa mlimi kapena malo ogulitsira zakudya zonse, ena angafunike kuyendetsa galimoto mtunda wautali kuti akapeze nyama yodyetsedwa ndi udzu.

Pakhoza kukhala kusiyanasiyana kosawoneka bwino pakakomedwe. Ng'ombe zodyetsedwa ndi msipu nthawi zambiri zimakhala zowonda ndipo zimatha kukhala ndi mawonekedwe osiyana.

Ngakhale ng'ombe yodyetsedwa ndi udzu imakhala ndi michere yambiri, pakadali pano palibe umboni wotsimikizira kuti ndiwathanzi kwambiri kuposa ng'ombe yodyetsedwa ndi tirigu munthawi ya chakudya chamagulu.

Pamapeto pake, kusankha kumatengera zomwe mumakonda komanso malingaliro anu. Anthu ena amakonda kudyetsedwa udzu, pomwe ena amakonda kudya tirigu. Yesani zonsezo ndikuwona yomwe mumakonda bwino.

Ngakhale udzu ndi ng'ombe yodyetsedwa ndi njere imasiyana mu michere yambiri, zomwe zimakhudza thanzi lanu zitha kukhala zofanana.

Mfundo yofunika

Ngakhale pali zovuta zambiri pankhani yazakudya, anthu ambiri amavomereza kuti chofunikira kwambiri ndikudya chakudya chenicheni.

Anthu ena amakonda kutenga lingaliro ili ndikungodya chakudya chenicheni chomwe chimadya chakudya chenicheni. Kupatula apo, udzu ndi zitsamba ndi chakudya chachilengedwe cha ng'ombe kuposa chimanga ndi soya.

Kumapeto kwa tsikulo, kusankha kumadalira zomwe mumakonda komanso malingaliro anu.
