Ukusetyenziswa kwabantu ngamafutha ngaphakathi kwemida efanelekileyo kubalulekile kwimpilo yakhe. Ziyakhusela umzimba kwi-hypothermia, zinike amandla, ngoncedo lwabo ukutya kakuhle kwamavithamini.
Ukususela kwiziphi iindlela
Zininzi iintlobo zamafutha. Iyanelisekile kwaye i-unsaturated incedo. Amafutha atshintshe ngamanzi ayiluncedo. Ziquka i-trans-isomers, ngaphandle kwezinye izinto ezi-fatty acid ezingenayo i-fatty acid, eziyingozi kakhulu, ngokungafaniyo nemafanayo efanayo yemvelaphi yemifuno. Amafutha atholakala kwimbewu yefleksi, i-sunflower, i-rapeseed, isipinashi. Iimpawu zeTrans - ngokushushumbisa ioli yohlaza kwi-200C kunye nokudlula kuyo i-hydrogen phantsi kwengcinezelo ephezulu. Njengomphumo wobushushu obuphezulu kunye noxinzelelo, ezinye ze-fatty acid ezingasetshenziswanga ziguqulwa zizalisiwe. Ioli ehlumayo iba yindyebo eqingqiweyo yemifuno, engaxhatshazelwanga kwinkqubo ye-oxidation, ingagcinwa ixesha elide, lingabi xabiso.
Umonakalo wee-trans-fats
Iimpawu zeTrans eziyingozi kubantu kukuba xa zenziwe nge oxygen, iamolekyu zabo zitshintsha isakhiwo. Baya kwindlela yokuchithwa kwe-hydrogenation ukusuka kwifom ye-cis (ukusuka kwii-molecule ezithe ngqo) ukuya kwifom ye-trans or kwi-curved. Oku kukhokelela ekubeni abanako ukufeza imisebenzi yabo yemvelo. Ukukwazi kwabo ukuphazamisa umonakalo weeseli, ukutshintsha i-molecule ye-unsaturated fatty acids inceda ekuphuhlisweni kweentlobo ezithile zesifo somhlaza. Ukusetyenziswa rhoqo kwamafutha atshintshe kunokukhokelela ekunyukeleni umxholo we-cholesterol embi egazini, ukuvela kwezifo ezahlukahlukeneyo zemithambo yegazi kunye nentliziyo.
Iimpawu zeTrans ziyakwazi ukuchukumisa ukuphuhliswa kweswekile sikashukela, ukukhuluphala, kuphazamise ngakumbi umgangatho wobisi lwebele, ngaloo ndlela kuthintela ubunzima kunye ngokupheleleyo kwimpilo yomntwana.
Xa zisetyenzisiwe, ukukhuselwa komzimba kunciphisa. Umuzhchin kukho ukunciphisa ubuninzi kunye nomgangatho wesilisa. Ukusebenza kakubi kwee-enzyme, kuzo kuxhomekeke ekunqumeni kwezinto ezihlukahlukeneyo zamachiza, i-carcinogens, iziyobisi ezithathwe.
Yiyiphi imveliso yinto ephakamileyo yamaxhoba
Ukuze sikwazi ukuthintela impembelelo engafanelekanga yezempilo, kufuneka sizame ukuthenga iimveliso ezincinci ezineoli yemifuno ekwakhekeni kwayo kwifomu echitshiweyo. Kodwa, ngelishwa, abavelisi abahlala bebonisa ukuba khona kwabo kwiibhile zeemveliso. Ukutya, apho iintlobo ze-trans zikhoyo kwizinto ezininzi, kubalulekile ukuba zibandakanye: i-mayonnaise, i-sauces, i-mayonnaise, i-lungkite, i-margarine, iimveliso ezigqityiweyo zentsimbi (i-cutlets, intlanzi kunye neentonga zenyama), i-popcorn, iifuni ezikhanyayo apho zipheleleyo okanye imfuyo yemifuno. Kwakhona, ukusetyenziswa kwama-creams, ukutya okukhawulezileyo, iisobho kwiingxowa, izityalo ezahlukeneyo ezomileyo azifunanga. Ama-intanethi athengiweyo, isinkwa, i-confectionery yazo zonke iindidi ziye zakhiwa i-argar, eyimpahla yerhafu.
Ayikho ngokupheleleyo kwimifuno, ibhotela ecocekileyo kunye nemveliso enje yezilwanyana njengekrimu, ushizi, i-fat intere. Kodwa ukuba ukubunjwa kweeshizi kuyinxalenye yeoli ye-vegetable, oko kuthi kuthi ngaphezu kweoli-hydrogenated, ukuba uthenge ioli elula, ayikho enye i-oyile yemifino kwimeko yayo eqinile.
Kuzo zonke ezi ngasentla, kucacile ukuba amafutha e-trans ayingxenye yeemveliso eziveliswe kumgangatho woshishino, ngoko kungcono ukutya yonke into ekhaya. Ukuba oku kungaphumeleli, nciphise ukusetyenziswa kwezi mveliso ubuncinci kwaye xa uthenge, funda ngokucophelele umxholo.
