Ngabe i-cholesterol ilungile noma imbi?
- ukwakheka kwamavithamini D;
- ngokuhlanganiswa kwamahomoni: i-cortisol, i-estrogen, i-progesterone, i-testosterone;
- ukwenziwa kwama-bile acid.
Ngaphezu kwalokho, i-cholesterol ivikela amangqamuzana egazi abomvu emithini eyi-hemolytic. Futhi nokho: i-cholesterol iyingxenye yamaseli obuchopho kanye nemicu yezinzwa.
I-cholesterol nokushibilika kwemithambo yegazi
Ukwanda kosayizi nenani le-cholesterol amana kulimaza ukukhanyiselwa kwemithambo futhi kuphazamise ukuhamba kwegazi. Imithambo yegazi engenakonakala egcwele ama-cholesterol plaques ibanga ukushayeka kwenhliziyo, imivimbo, ukuhluleka kwenhliziyo nezinye izifo zemithambo.
Nge-cholesterol ephezulu, kubalulekile ukucabanga kabusha ngendlela yokuphila futhi ulahle imiphumela yezizathu ezinciphisa ukuqina kwemithambo yegazi, kwakheka ama-microcracks futhi ngaleyo ndlela kubangele ukukhiqizwa kwe-cholesterol esibindini somuntu:
- Ukukhuluphala nokusetshenziswa kwamafutha we-trans.
- Ukuntuleka kwefayibha ekudleni nasemathunjini.
- Ukungasebenzi.
- Ukubhema, utshwala nobunye ubuthi obungamahlalakhona (ngokwesibonelo, ukuphuma kwezimoto kwezimboni nasemadolobheni, ubuthi bendawo - - umanyolo kwimifino, izithelo namanzi asemhlabathini).
- Ukuntuleka kokudla kwezicubu zemithambo (amavithamini, ikakhulukazi u-A, C, u-E no-P, ukulandelela izinto nezinye izinto zokwenziwa kabusha kweseli).
- Inani elikhulayo lama-radicals wamahhala.
- Isifo sikashukela mellitus. Isiguli esinesifo sikashukela sihlala sithola inani elithile le-cholesterol egazini.
Kungani imikhumbi ihlushwa yisifo sikashukela futhi kukhiqizwa inani elikhulayo lezinto ezinamafutha?
Isifo sikashukela ne-cholesterol: kwenzeka kanjani lokhu?
Ku-mellitus yesifo sikashukela, izinguquko zokuqala ezingenampilo emikhunjini yomuntu. Igazi elimnandi linciphisa ukuqina kwabo futhi lenyusa ukubabaza. Ngaphezu kwalokho, ushukela ukhiqiza inani elikhulayo lama-radicals wamahhala.
Esikhathini sikashukela, ukukhiqizwa kwama-radicals mahhala kukhuphuka kakhulu. Ukuqina kwemithambo yegazi nokunciphisa ukuhamba kwegazi kwenza izinqubo zokuvuvukala emithanjeni nasezithanjeni ezizungezile. Ibutho lama-free radicals enza ukulwa ne-foci yokuvuvukala okungapheli. Ngakho-ke, kwakhiwa ama-microcracks amaningi.
Imithombo yama-radicals esebenzayo ayikwazi ukuba ngama-molecule we-oksijini kuphela, kodwa futhi ne-nitrogen, chlorine ne-hydrogen. Isibonelo, emsini wentuthu kagwayi, kuhlanganiswa izinhlanganisela ezisebenzayo ze-nitrogen nesibabule, zichitha (oxidize) amaseli wamaphaphu.
Ukulungiswa kwe-Cholesterol: Okuhle nokubi
Indima ebalulekile enqubweni yokwakhiwa kwama-cholesterol deposits idlalwa ngokuguqulwa kwento enamafutha. I-Chemical cholesterol ngotshwala obunamafutha. Akuncibilikisi ku-ketshezi (egazini, emanzini). Egazini lomuntu, i-cholesterol ihlangana namaprotheni. Amaprotheni athile lawo angabathuthi bama-cholesterol molecule.
- umthamo omkhulu we-lipoproteins (HDL). Isisindo esiningi se-molecule egazini, musa ukwakheka kokuqala noma ukubeka ezindongeni zemithambo yegazi (cholesterol plaques). Ukuze kube lula ukuchaza, lo mnotho we-cholesterol-protein omkhulu ophakeme ubizwa ngokuthi "muhle" noma i-alpha-cholesterol.
- density lipoproteins (LDL). Isisindo esincane se-molecule egazini futhi sithambekele ekushayaneni kwezulu. Bakha okubizwa ngokuthi yi-cholesterol plaque ezindongeni zemithambo yegazi. Le yinkimbinkimbi ibizwa nge- "bad" noma i-beta cholesterol.
Izinhlobo "ezinhle" nezithi "ezimbi" ze-cholesterol kumele zibe segazini lomuntu ngamanani athile. Benza imisebenzi ehlukene. "Okuhle" - isusa i-cholesterol kwizicubu. Ngaphezu kwalokho, ithumba i-cholesterol eyeqile futhi iyisuse emzimbeni (ngokusebenzisa amathumbu). "Okubi" - kuthuthela i-cholesterol kwizicubu zokwakhiwa kwamaseli amasha, ukukhiqizwa kwama-hormone nama-bile acid.
Ukuhlolwa kwegazi kwe-cholesterol
- Ngasikhathi sinye, ama-20% esamba esiphelele se-cholesterol kufanele abalwe yi-lipoprotein “enhle” (ukusuka ku-1.4 kuye ku-2 mmol / L kwabesifazane futhi ukusuka ku-1,7 kuye ku-mol / L kwabesilisa).
- Ama-70% e-cholesterol ephelele kufanele alethwe ku-lipoprotein “embi” (aze afike ku-4 mmol / l, kungakhathalekile ubulili).
Ukuqhubeka ngokweqile kwenani le-beta-cholesterol kuholela ku-vasher atherosulinosis (okuningi ngalesi sifo kungatholakala kulesi sihloko). Ngakho-ke, iziguli ezinesifo sikashukela i-mellitus zithatha lolu vivinyo njalo ezinyangeni eziyisithupha (ukuthola ubungozi bezinkinga ze-vascular futhi zithathe izinyathelo ezifika ngesikhathi zokunciphisa i-LDL egazini).
Ukuntuleka kwanoma imuphi ama-cholesterols kuyingozi nje ngokweqile kwabo. Ngamanani angenele we- "high" alpha-cholesterol, inkumbulo nokucabanga kubuthakathaka, kuvela ukudangala. Ngokuntuleka kwe-beta cholesterol "ephansi", ukuphazamiseka ekuthuthweni kwe-cholesterol kwifomu yamaseli, okusho ukuthi izinqubo zokwenziwa kabusha, ukukhiqizwa kwama-hormone ne-bile kunciphisa, ukugaya ukudla kuyinkimbinkimbi.
Isifo Sikashukela kanye Ne-cholesterol Ukudla
Umuntu uthola ngokudla kuphela ama-20% kholesterol. Ukunciphisa i-cholesterol kumenyu akuvimbi njalo ukufakwa kwe-cholesterol. Iqiniso ngukuthi kwimfundo yabo, akwanele nje ukuba ne-cholesterol "embi". I-Microdamage emikhunjini lapho ifomu le-cholesterol lifaka khona isidingo.
- Inyama enamafutha (ingulube, iwundlu), ukudla kwasolwandle okunamafutha (i-caviar ebomvu, i-shrimp) ne-offal (isibindi, izinso, inhliziyo) kukhawulelwe. Ungadla inkukhu yokudla, inhlanzi enamafutha amancane (i-hake, i-cod, i-pike perch, i-pike, i-flounder).
- Amasoseji, inyama ebhemayo, inyama ekheniwe nenhlanzi, imayonesi (equkethe amafutha ama-trans) ayafakwa.
- I-confectionery, ukudla okusheshayo nama-chips akufakiwe (imboni yokudla yanamuhla isebenza ngesisekelo samafutha ashibhile noma uwoyela wesundu oshibhile).
- Amafutha emifino (i-sunflower, i-lined, i-olive, kodwa hhayi i-palm - aqukethe amafutha amaningi agcwele nama-carcinogens, hhayi i-soy - izinzuzo zika-oyili we-soya zincishiswa amandla akhe okuqina egazi).
- Imikhiqizo yobisi enamafutha amancane.
Izinyathelo zokunciphisa i-cholesterol kushukela
- Umsebenzi womzimba;
- ukwenqaba ukuzikhipha ubuthi;
- ukukhawulwa kwamafutha kwimenyu;
- ukunyuka kwe-fiber kumenyu;
- ama-antioxidants, ukulandelela izinto, amavithamini;
- kanye nokulawulwa okuqinile kwama-carbohydrate ekudleni ukuze kuncishiswe inani loshukela egazini kanye nokwenza ngcono ukuqina kwemithambo yegazi.
Amavithamini angama-antioxidants anamandla (amavithamini kanye nesidingo sawo sansuku zonke, bheka le ndatshana). Balawula inani lama-radicals wamahhala (qiniseka ukuthi ukulinganisa kokuphendula kwe-redox). Esikhathini sikashukela, umzimba uqobo awukwazi ukubhekana nenani elikhulu lama-oxidizing agents (ama-radicals).
- I-antioxidant enamandla ihlanganiswe emzimbeni - i-glutathione engamanzi encibilikayo. Ikhiqizwa ngesikhathi sokuzivocavoca ngokomzimba lapho kukhona amavithamini B.
- Kutholwe kusuka ngaphandle:
- amaminerali (i-selenium, i-magnesium, ithusi) - ngemifino nokusanhlamvu;
- amavithamini E (imifino, imifino, i-bran), C (izithelo ezimuncu namajikijolo);
- ama-flavonoids (khawulela inani le-cholesterol "ephansi" - etholakala ezithelo zikawolintshi.
