Okuqukethwe
Lezi yizinto ezibalulekile emzimbeni wethu. Emzimbeni womuntu, balawula ukungena kwezingqamuzana zeseli, futhi kuthinta nezinqubo ze-metabolic. Lezi zinto ziyingxenye ebalulekile yama-lipids futhi zibalulekile empilweni yethu nasekuheheni kwethu.
Ukudla okunothe kweSterol:
Izici ezijwayelekile zama-sterols
I-Sterols iyingxenye ebalulekile yamafutha emifino nezilwane. Bangabamaqembu e-polycyclic alcohol futhi batholakala kulwelwesi lwazo zonke izinto eziphilayo.
Ama-Sterols atholakala emvelweni ezifundazweni ezimbili: ngesimo sama-alcohols amahhala, nangendlela yama-esters wamafutha aphezulu. Ngaphandle, ziyisithako samakristalu, cishe asincibiliki emanzini.
AmaSterols atholakala ezintweni eziphilayo zezilwane nabantu abizwa ngama-zoosterol. Okudume kakhulu kulezi yi-cholesterol.
Izazi zesayensi yezinto eziphilayo ezincane ziphinde zahlonza olunye uhlobo oluvamile - lezi ama-sterol ezitshalo eziphansi neziphakeme, ezibizwa ngokuthi ama-phytosterol. Lezi yi-B-sitosterol, i-campesterol, i-stigmasterol, i-brassicasterol. Asuselwa ezintweni zezitshalo ezifana namafutha e-soya namafutha e-rapeseed.
Ngaphezu kwalokho, i-mycosterols (i-fungal sterols, isibonelo, i-ergosterol), kanye ne-sterols ye-microorganisms, isatholakala emvelweni. I-Ergosterol ilusizo kakhulu empilweni yomuntu. Ngaphansi kwethonya lokukhanya kwe-ultraviolet, iphenduka ibe yi-vitamin D. I-sterols yezimboni isetshenziselwa ukukhiqiza amahomoni, kanye namavithamini eqembu D.
Isidingo sansuku zonke sama-sterols
Izazi zokudla okunomsoco zithi isilinganiso sansuku zonke se-cholesterol akufanele seqe ama-300 mg. Ama-sterols ezitshalo anconywa ukuthi asetshenziswe ngenani lama-2-3 amagremu ngosuku.
Kubantu abanezinkinga zenhliziyo nemithambo yegazi, isilinganiso sibalwa ngokuya ngesimo sabo somzimba nezincomo zikadokotela.
Isidingo sama-sterols sanda nge:
- i-cholesterol ephezulu yegazi;
- amasosha omzimba buthakathaka;
- isimo se-pre-stroke kanye ne-pre-infarction (kusetshenziswa ama-phytosterol);
- inani elinganele lamavithamini A, E, K, D emzimbeni;
- ngokungabi namandla;
- ngesikhathi sokukhulelwa nokuncelisa;
- uma kwehle i-libido;
- uma kunesidingo, amandla okushisa angeziwe;
- ngomsebenzi onzima womzimba;
- ngokucindezeleka okukhulu kwengqondo;
- ngokubonakaliswa kwezimpawu zesifo se-rickets (i-ergosterol isetshenziselwa ukwelashwa).
Isidingo se-sterols siyancipha:
Lapho zingekho zonke lezi zinto ezingenhla.
Ukugaya kwama-sterols
Inqubo yokwenziwa kwama-sterol ezitshalo isebenza kakhulu kuneyezilwane. Lokhu kutholakala kuhlotshaniswa neqiniso lokuthi isibopho samakhemikhali sama-phytosterols amelana kancane nokucubungula kujusi yesisu. Mayelana nalokhu, zisetshenziselwa ukukhiqizwa kwamandla okuphuthumayo.
Ama-Zoosterol, kunalokho, ayakwazi ukumelana nokuqhekeka isikhathi eside. Futhi lokhu, kusiza umuntu ukuba azizwe elambile. Kukholelwa ukuthi amadoda avame ukunikeza okuthandwayo emikhiqizweni equkethe ama-sterols ezilwane, kanti abesifazane - ukutshala ama-sterol.
Izakhiwo eziwusizo zama-sterols nomphumela wawo emzimbeni
Ngokuya ngocwaningo olwenziwe ngongoti bomnotho baseRussia, imiphumela emihle yama-sterol emzimbeni womuntu itholakele futhi yafakazelwa.
Ama-phytosterol asetshenziselwa ukwehlisa amazinga we-cholesterol egazini, okubaluleke kakhulu ku-atherosclerosis. Zinciphisa ubungozi bokushaywa unhlangothi nokuhlaselwa yinhliziyo. Banomsebenzi obizwa ngama-antioxidant. Kuqinisa amasosha omzimba.
Ngaphezu kwalokho, ama-sterol ayisithako esiyisisekelo samavithamini A no-E emafutheni emifino, nakuvithamini D ezilwaneni. Ekhemisi, ama-sterols asetshenziselwa ukukhiqiza ama-hormone e-steroid, kanye nokwenza i-vitamin D neminye imithi.
Ukusebenzisana nezinye izinto:
Ama-Sterols angamakhemikhali awuketshezi alungele i-carotene (i-provitamin A), kanye namavithamini K, E no-D. Ngaphezu kwalokho, ama-sterols enza umsebenzi wokuthutha emzimbeni. Baphatha amaprotheni kuzo zonke izitho zomuntu nezicubu.
Izimpawu zokushoda kwama-sterols emzimbeni
- i-atherosclerosis (ngokuntuleka kwama-phytosterol);
- ukukhathala;
- ukukhathala kwemizwa;
- ukushintsha kwemizwelo;
- kwehle ukusebenza kocansi;
- isimo esibi sezipikili;
- ubucayi bezinwele;
- ukungalingani kwe-hormonal;
- amasosha omzimba aphansi;
- ukuguga ngaphambi kwesikhathi.
Izimpawu zama-sterols ezeqile emzimbeni
- i-atherosclerosis (i-cholesterol eyeqile);
- amazinga okwanda kwegazi;
- kusebenze ukuthuthukiswa kwama-gallstones namatshe we-hepatic;
- ukwenziwa buthaka kwamathuluzi e-osteochondral;
- ukwanda komfutho wegazi;
- ubuhlungu enhliziyweni;
- izinguquko emsebenzini wesibindi nobende.
Izici ezithinta inani lama-sterols emzimbeni
Isici esiyinhloko esithinta okuqukethwe kwe-phytosterols emzimbeni ukudla. Ama-zoosterol angakhiwa emikhiqizweni yemvelaphi ye-carbohydrate namafutha, futhi angene emzimbeni wethu kanye nokudla. Ukungasebenzi ngokomzimba kuholela ekuqongeleleni ama-sterols emzimbeni, kodwa ngesikhathi esifanayo kunciphisa ukumuncwa kwawo.
Ama-Sterols wobuhle nempilo
Ngeshwa, iningi lobulili obulungile, ngokulandela ivolumu oyifunayo, liyenqaba ukudla amafutha - imithombo yama-sterols. Ngakolunye uhlangothi, leli yithuba langempela lokunciphisa isisindo. Kepha uzilungisa kuphela uma isisindo esiningi sikhona ngempela futhi sivimbela umuntu ekuholeni impilo esebenzayo.
Ngaphandle kwalokho, kunengozi yokuba nolaka, uboya obufiphele, isikhumba esomile nezinzipho ezinamavila. Ngaphezu kwalokho, ukuntuleka kwama-sterols nakho kuholela ekwehliseni amandla okubuka kanye nezinkinga zokuzala.
Imiphumela yokudla okunamafutha aphansi kungabhekwana nayo kuphela ngokudla okulinganiselayo kwama-sterol, kudla amafutha ezilwane nemifino.
