Inama - okulungileyo kunye nomonakalo

Idatha epapashwe ke engamashumi amathathu yokugqibela ibonisa ukuba amafutha elizele zezona nobangela nesifo sentliziyo. Kodwa namhlanje, izazinzulu kwabonisa ukuba oku kuyinyaniso. Uphononongo lubonise ukuba abantu abatsha musa ukuba ngaphandle kwamafutha ukusuka otya ngayo. Ukuba sithethe ngayo abadala, imingcele ukwamkelwa kwabo nangoku esebenzayo ngokwenzululwazi.

Ezinye izazinzulu zikholelwa ukuba amafutha ayegcwele ezinento yokwenza yemfuza abantu ababandakanyeka kwinkqubo pathways, amacandelo noshowo inwebu eziphilayo, njl Abasebenzi University of eCardiff wabonisa ukuba amanqatha ubisi lunciphisa ubungozi isifo sentliziyo kunye imithambo yegazi. Ngoko ke, amagqirha kucetyiswa ukuba nangoku ukusebenzisa ubisi yonke, hayi skim. Ukusetyenziswa kwale mveliso ngabantwana kunye nabantu abaselula benze okubi ngaphezu okulungileyo. Xa ukudla kuyimfuneko ukunciphisa inani "nezingalunganga" kwelentshona ye-amafutha, iswekile kunye netyuwa.

Namhla siyazi ukuba amafutha ayegcwele musa ukuba inzuzo ubunzima. Ngokuqhelekileyo, le nkqubo kubangelwa isixa esikhulu ekudleni. Ukusetyenziswa kwe-mali ubuncinane amanqatha kubangela uphuhliso nezifo ezininzi. Ngokuyintloko, oku edibene ngamanqatha-enyibilikayo iivithamini A, D, E, K, F. Ezi zinto ziya nje ukuba zifunxwe ngumzimba ngaphandle lipids eyaneleyo. Ngenxa yoko, esihanahanisa- apho kunye avitaminosis. Asimele silibale ukuba zombini iihomoni steroid kunye acids inyongo isuselwa lipids. Amafutha - ubushushu kakhulu, zingumthombo obalulekileyo eneji, amanzi kunye zeendawana iqala ukuba Yindibanisela eziliqela iikhompawundi bioactive ukuya ephilayo.

Kwaye kusafuneka ukuba bana phandle zithini amafutha. Chemistry kwamafutha (lipids)

Bonke bephela zahlulwe zibe ngamaqela amathathu amakhulu: ilula, inzima nezakhi. Iqela lokuqala zezo kwenziwa glycerol (utywala trihydric) kunye fatty ephakamileyo. Eli qela libandakanya triacylglycerols, sterols kunye amafutha. Le molecule iqulethe glycerol lipid ezintsonkothileyo, fatty ephakamileyo, asidi phosphate kunye sulfate, izinto nitrogen, iikhabhohayidrethi kunye nezinye iikhompawundi ezininzi. Yezabelo ziquka lipids carotene, okunamafutha acid, alkoholi ephezulu, ezinye iivithamini ezityebileyo-awonayo , njl

Ngokumalunga fatty ephakamileyo nezikhongozelo, kodwa ubukhulu becala zimelwe acyclic isinyibiliko unsaturated okunamafutha. Ukubunjwa amanye amafutha asidi elibujikele carboxylic, kunye hydroxyacids. amafutha kugcwale ziqulathe amanqanaba aphezulu palmitic, stearic, myristic acid. Kuyinto eyaziwayo ukuba ezinye asidi ezihluthiyo okunamafutha akukho ziveliswa emzimbeni okanye ukufaka kwi asanelanga, imali ubuncinane. Kulo mba, zibizwa kunye kubalulekile okanye ufunwayo. Kweli qela fanele CD, linoleic, linolenic acid. fatty Kubalulekile oyile mali imifuno eyaneleyo. Amafutha ubisi iqulethe isixa esikhulu se CD acid. Monounsaturated amafutha ibe isixa omkhulu oleic acid.

Xa abantu, nenqatha ifumile (triacylglycerides) zisetyenziswa izinto amandla. Ezi zibandakanya nezo imvelaphi yezilwanyana, kunye nemifuno esiqinileyo. Triacylglycerols kwiimveliso ezininzi inyama nezinto ezidliwayo okunamafutha kunye neemveliso zobisi, itshokolethi kunye neemveliso confectionery. kukutya kakhulu kwezi amafutha kunokubangela ukwanda uyondelelwano lwee- cholesterol emzimbeni. Ngoko-ebizwa cholesterol "yezifo" mayifakwe kwi iindonga imithambo yegazi, nto leyo, ebangela uphuhliso izifo ezifana yegazi, luthambe semithambo yaphulwe, kwakheka legazi.

Zokudla bacebisa ukutya imali encinci namafutha. Eyingozi kakhulu umzimba zithathwa olun-amafutha. isomers ezinjalo akhiwa ngenxa isenzo yeemeko ngokwasemzimbeni kunye kwemichiza amafutha yemifuno, ezakutshintsha imeko yabo ukusuka kulwelo ukuya okuqinileyo. Kwabo ziquka zebhotolo kunye confectionery anuka upheka. Ukuba uyakwazi ukuvelisa nomphumo umhlaza.
