Yankho: Canola, rapeseed kapena rapeseed mafuta ndi mafuta okonzedwa omwe angawononge thanzi lanu. ndipo chifukwa chake, sizogwirizana ndi keto, koma pali njira zina zathanzi zomwe zili.

Funso loyamba lomwe limabwera m'maganizo kwa ogwiritsa ntchito ambiri ndilakuti: Kodi mafuta a canola, rapeseed ndi rapeseed ndi ofanana? Ndipo ngakhale kuti m’malo ambiri, pofuna kuphweka, amati inde, zoona zake n’zakuti sali. Kufotokozera kwa izi ndikwambiri. Koma mwachidule, mafuta a rapeseed ndiye mtundu woyamba. Pafupifupi magawo awiri mwa atatu a mafuta a monounsaturated mu mafuta a rapeseed ndi erucic acid, 22-carbon monounsaturated fatty acid yomwe imagwirizanitsidwa ndi matenda a Keshan, omwe amadziwika ndi zironda za mtima za fibrotic. Chifukwa cha izi, kumapeto kwa zaka za m'ma 70, pogwiritsa ntchito njira yowonongeka kwa majini yomwe imaphatikizapo kugawaniza mbewu, obereketsa a ku Canada adapanga mitundu yosiyanasiyana ya rapeseed yomwe imapanga mafuta a monounsaturated otsika mu erucic acid ya 22 carbons ndi oleic acid ya 18. carbons. 

Mafuta atsopanowa amatchedwa mafuta a LEAR. Koma kuti apititse patsogolo kutchuka kwake komanso popeza adachokera kukusintha kwa Canada, adamaliza kutchedwa mafuta a canola. Choncho yankho la funsolo Kodi canola ndi mafuta a rapeseed ndi ofanana? Yankho ndiloti ayi. Mwachidziwitso, mafuta a rapeseed amatchedwa rapeseed yoyambirira, pomwe mafuta a canola amaganiziridwa kuti amachokera ku rapeseed yosinthidwa mwachibadwa. 

Kuyesera kochuluka kwachitika pa mafuta a rapeseed ndi canola. Monga tawonera kale, kafukufuku wasonyeza kuti mafuta ogwiriridwa amayambitsa mavuto a mtima (fibrotic zilonda), koma mpaka pano, palibe maphunziro omwe adachotsa mafuta a canola (LEAR). Mpaka ofufuza a ku Canada adayesanso mafuta a LEAR mu 1997. Anapeza kuti ana a nkhumba omwe amadyetsa mkaka m'malo mwa mafuta a canola amasonyeza zizindikiro za kuchepa kwa vitamini E, ngakhale kuti mkaka wolowa m'malo unali ndi vitamini E wokwanira. kwa dongosolo labwino la mtima. M'nkhani ya 1998, gulu lomwelo la kafukufuku linanena kuti nkhumba zodyetsera mafuta a canola zinatsika mu chiwerengero cha mapulateleti komanso kukula kwa mapulateleti. Nthawi yokhetsa magazi inali yayitali mu ana a nkhumba omwe amadyetsedwa mafuta a canola ndi mafuta a rapeseed kuposa mafuta ena omwe amadyetsedwa. Zosinthazi zidachepetsedwa ndi kuwonjezeredwa kwamafuta ochulukirapo kuchokera ku batala wa koko kapena _mafuta a kokonati_ ku zakudya za ana a nkhumba. Zotsatirazi zidatsimikiziridwa ndi kafukufuku wina patatha chaka chimodzi. Mafuta a canola adapezeka kuti amachepetsa kukula kwachitukuko kwa kuchuluka kwa mapulateleti.

Pomaliza, kafukufuku yemwe adachitika ku Health and Toxicology Research Divisions ku Ottawa, Canada, adapeza kuti makoswe amawetedwa chifukwa cha kuthamanga kwa magazi komanso makonda a sitiroko adafupikitsa nthawi ya moyo akapatsidwa mafuta a shuga. Zotsatira za kafukufuku wina pambuyo pake zinasonyeza kuti zolakwazo zinali mankhwala a sterol mu mafuta, omwe "kupanga nembanemba ya cell kukhala yolimba”Ndi kuthandizira kufupikitsa moyo wa nyama.

Maphunziro onsewa amalozera mbali imodzi: mafuta a canola siabwino kwenikweni pamtima. Monga mafuta a rapeseed, omwe adatsogolera, mafuta a canola amalumikizidwa ndi zotupa zamtima. Zimayambitsanso kusowa kwa vitamini E, kusintha kosafunikira m'mapulateleti a magazi, ndi kufupikitsa moyo wa makoswe omwe amadwala sitiroko pamene anali mafuta okha m'zakudya za nyama. Kuphatikiza apo, zikuwoneka kuti zikulepheretsa kukula, chifukwa chake a FDA salola kugwiritsa ntchito mafuta a canola pazakudya za ana.
Pambuyo pa zonsezi, tikhoza kunena momveka bwino kuti mafuta a rapeseed, canola kapena rapeseed si abwino kwa thanzi lanu ndipo chifukwa chake sichigwirizana ndi keto. Pamlingo weniweni, mafutawa sakhala owopsa kuposa ena monga mafuta a mpendadzuwa. Koma ngati tiyenera kusankha ndipo tikufuna a mbewu, mosakayikira njira yabwino kwambiri idzapitirizabe kukhala mafuta a azitona.
