Abesifazane abaningi babona amafutha kuzo zonke izinhlobo njengezitha zomuntu omuhle. Nokho, hhayi kuzo zonke izimo lokhu kuyiqiniso. Noma kunjalo, lolu daba kufanele luhlakazwe ngokuningiliziwe ukuze kugweme izahlulelo eziningi ezingalungile.
Amafutha okulungile nokungalungile
Ngaphambi kokuba sihlukanise zonke izinhlobo ezikhona zamafutha kulabo okudingekayo emzimbeni womuntu kanye nalawo okulimazayo kuwo, sizoqonda ukuthi yimaphi amafutha.
Amafutha, okubizwa nangokuthi i-triglycerides, yi-lipids ekilasini lawo futhi ayizinhlanganisela eziphilayo ze-fatty acids ne-glycerol esters. Ngokuvamile, lokhu kuchazwa kwamakhemikhali akudingekile ukwazi, kubalulekile ukuqonda ukuthi wonke amafutha ahlukaniswe abe izinhlobo ezimbili: egcwele futhi engasetshenzisiwe. Into esemqoka ehluke ngayo yilezi zakhi zamakhemikhali, okuvela kuyo umahluko phakathi kwezakhiwo zabo.
Amafutha anelisiwe
Amafutha anelisekile ayingxenye yamafutha esilwane esiqinile futhi alula kakhulu esakhiweni sabo. Lolu hlobo lwamanoni lufakwe ngokushesha emzimbeni ngesimo se-adipose tissue. Lokhu kufaka:
- ibhotela, ushizi;
- amafutha wezinso, amanoni angaphakathi, amafutha amhlophe enyama (kubandakanya isikhumba senkukhu);
- i-margarine, isakazeka;
- isundu kanye namafutha kakhukhunathi.
Lolu hlobo lwamafutha luyingozi kunazo zonke empilweni, ngoba linciphisa ukukhanya kwe-arteries, okuphumela ngenxa yokuhlasela kwenhliziyo, ukushaywa kanye nezinye izifo zenhliziyo.
Amafutha athile aphikisiwe kakhulu kulabo abafuna ukuqeda isisindo esiningi. Ukusetshenziswa okusebenzayo kwamafutha anjalo kungaholela ekuphazanyeni kwe-metabolism, ngenxa yalokho amafutha atholakale emzimbeni kakhulu.
Noma kunjalo, amafutha agcweleyo athatha kokubili umonakalo futhi azuze: awakwazi ukuvinjelwa nhlobo, ngoba azalise umsebenzi wabo oyinkimbinkimbi ekusetshenzisweni kwemithi. Izakhamuzi zeluleka ukuba zithole ukudla okuvela kumafutha agcwele angaphezu kuka-7% wamakorikhi ngosuku.
Amafutha angasetshenzisiwe
Ama-acids ama-unsaturated ayinhlobo ewusizo kakhulu yamafutha. Zitholakala ngokuyinhloko ekudleni kwamafutha kanye nemifino yemifino. Futhi, leli qembu lihlanganisa izinto ezilandelayo:
- I-Monounsaturated fatty acids. Loluhlobo lwe-asidi lukhiqizwa ngumzimba womuntu. Bamba iqhaza ekulawulweni kwegazi - isibonelo, i-oleic acid, ecebile ngamafutha omnqumo, ehlisa izinga le-cholesterol egazini.
- Amafutha e-Polyunsaturated (i-omega-6) amafutha abalulekile emzimbeni wesintu. Zitholakala emafutheni omifino - i-sunflower, soy. Ngokuhlanganiswa nesakhiwo esiyinkimbinkimbi se-omega-3 sinomthelela ekuthuthukiseni impilo yomzimba wonke.
- Polyunsaturated fatty acids (omega-3). Lona uhlobo oluwusizo kakhulu lwamafutha, ngendlela, agcwele amafutha enhlanzi, ajwayele abaningi kusukela ebuntwaneni. Kungenxa yalezi zinhlobo ze-polyunsaturated ukuthi amafutha okudoba ibhekwa njengenye yezinto ezingcono zokudla okunomsoco. Ngaphezu kokudoba amafutha, i-omega-3 complex ingatholakala kwi-rapeseed, soya,
Amafutha e-flax, noma kunjalo, ukutshala okuhlukile akukwazi ukubeka ngokugcwele ama-acids ovela emanzini. Ngendlela, ukuze kuqinisekiswe ukuthi umzimba unikezwe le-asidi, umane nje izikhathi ezingu-2-3 ngesonto ukwengeze ekudleni izitsha ezivela ezinhlanjeni ezinamafutha (okuphawulwe: enyakatho yezinhlanzi, i-omega-3 equkethe ngaphezulu). - Okuwukuphela kokulimaza okuyikho kuphela amafutha okudlulisa , okuyiwohlobo lamafutha angenalutho. Lezi zinhlobo zamafutha, ngokusho kososayensi baseMelika, ingenye yezimbangela zesifo senhliziyo.
Ukufingqa, kubalulekile ukuphawula ukuthi amafutha ayadingeka emzimbeni, noma kunjalo, kufanele ukuthi "ilungile", amafutha angenalutho anamafutha ayimfuneko emzimbeni.
