Chii chinonzi ketone?

Ketoni makemikari anogadzirwa muchiropa, kazhinji semhinduro yemetabolism yekuve mukudya ketosis.

Izvi zvinoreva kuti iwe unogadzira ketoni kana iwe usina yakakwana yakachengetwa glucose (kana shuga) kuti ishanduke kuva simba. Kana muviri wako unonzwa sekunge unoda imwe nzira kune shuga, inoshandura mafuta kuita ketoni.

Iwe unogona kufunga kuti iwe unofanirwa kunge uri pane ketogenic kudya kana kuve mune mamiriro e ketosis kuti uve nemaketone muropa rako. Asi iwe une ketoni kazhinji.

Muchokwadi, iwe unogona kunge uine ketoni muropa rako izvozvi ( ¹ ).

Saka chii chinokonzera ketoni? Ndezvipi? Uye nei uchifanira kuva nazvo?

Verenga kuti uwane tsananguro izere yemaketoni uye basa rawo seyokutanga simba sosi kana uchinge wapinda ketosis.

Chii chinonzi ketone?

Ketoni, inozivikanwawo se "ketone miviri," inogadzirwa nemuviri inopwanya mafuta kuti iwane simba. Izvi zvinongoitika chete kana carb yako yekudya yakadzikira uye muviri wako uchichinja kuita ketosis ( ² ).

Aya mashandisiro anoita

• Paunenge uri super low-carb, uchitsanya kwenguva yakareba, kana kurovedza muviri zvakanyanya, muviri wako unozowana simba kubva mukupisa shuga (inozivikanwawo seshuga yeropa) uye zvitoro zveglycogen (inozivikanwawo seshuga dzakachengetwa).
• Kana glucose yapera, muviri wako unotanga kutsvaga imwe nzvimbo yehuni. Panyaya yekudya kwe ketogenic, inonyanya kukora.
• Panguva ino, muviri wako unotanga kuputsa mafuta ekudya uye mafuta emuviri kuti awane huni, maitiro anozivikanwa se beta-oxidation. Muviri wako unogona kushandisa fatty acids kuita huni, kuwedzera kune mamwe makomisheni anonzi ketone, ayo anoumbwa muchiropa chako.
• Vanhu vari pakudya kwe ketogenic vanonyanya kuderedza kudya kwavo kwecarb nekuda kwechikonzero ichi: kugadzira ketoni dzesimba.

Vanhu vazhinji vanoshandisa mabhenefiti eketosis (kushomeka kwecarb uye kutsva kwemafuta akawanda) kubatsira kudzikisa BP, kuderedza kushuvira, kuvandudza cholesterol, kuwedzera kuonda, kuwedzera simba, nezvimwe.

Mirira - MaKetone ane Ngozi here?

Ketoni ndiyo imwe sosi yehuni yemuviri wako. Kunyangwe iwe ungave usiri kujairana navo seglucose, iwo akachengetedzeka makomisheni aunogona kushandisa kune simba.

Paunoburitsa miviri yeketone, chero maketone akawandisa ayo muviri wako usingakwanise kushandisa anobviswa kuburikidza nekufema kwako kana weti.

Inguva chete ketoni inogona kuva dambudziko kana iwe une rudzi rwekutanga kana 1 chirwere cheshuga, uye kushaya insulini kunokonzera kuunganidza ketoni uye glucose muropa rako. Ichi chirwere chinozivikanwa se ketoacidosis uye chakafukidzwa zvakadzama gare gare muchinyorwa chino.

Mhando dzemiviri yeketone

Saka chii chimwe chaunofanira kuziva? Kune kutanga, kune tekinoroji matatu marudzi emitumbi ye ketone:

• Acetoacetate (AcAc).
• Beta-hydroxybutyric acid (BHB).
• Acetone.

Ose ari maviri acetoacetate uye beta-hydroxybutyrate ane basa rekutakura simba kubva pachiropa kuenda kune mamwe matishu ari mumuviri wako.

Ketone kugadzirwa

Munguva yeketogenesis, iyo iyo miviri yeketone inoumbwa kubva pakuparara kwemafuta acids, acetoacetate ndiyo yekutanga ketone yakagadzirwa.

Beta-hydroxybutyrate inoumbwa kubva kuacetoacetate. (Inofanira kucherechedzwa kuti BHB haisi yehunyanzvi ketone nekuda kwechimiro chemakemikari, asi inoonekwa seketone nekuda kwehukama hwayo kune mamwe metabolites uye basa rayo mumuviri wako.)

Acetone, inova ndiyo yakapfava uye isinga shandiswe ketone muviri, inogadzirwa zvega sechigadzirwa cheacetoacetate ( ³ ).

Kana acetone isingade simba, inopera uye ichibuda kunze kwemuviri semarara kuburikidza nekufema kana weti. Acetone ndiyo inokonzera kunhuwa muchero hunhu pakufema kana mumwe munhu ari mu ketosis kana ketoacidosis.

Sei muviri wedu uchishandisa ketoni?

Kwezviuru zvezvizvarwa, vanhu vakavimba neketoni kuti vawane simba kana glucose isipo.

Semuyenzaniso, madzitateguru edu angangove aiwanzosangana nenguva apo chikafu chakanga chisisawanikwe nekukurumidza, kungave nekuda kwekugadzirwa kwechikafu kana kuwanikwa. Uye kunyange nhasi, miviri yedu inoshamisa pakujairana nekupisa miviri ye ketone yehuni.

Mamwe mabhenefiti anoshanda emaketone anogona kusanganisira:

• Kuwedzera kwekuita kwepfungwa, nekuti ketoni dzinoyambuka zviri nyore muropa-brain barriers kuti ipe uropi hwako nekukurumidza uye inoshanda mafuta.
• Simba remuviri: Kana uchinge usingavimbi neglucose yehuni, muviri wako unowedzera kushanda pakupisa mafuta panguva yekurovedza muviri. Izvi zvinoreva kupisa kwemafuta akawanda uye simba rakatsiga kana uchinge wapinda ketosis ( ⁴ ) ( ⁵ ).

Maitiro ekuyedza ako ketone mazinga

Pane nzira nhatu dzakasiyana dzekuyedza mazinga eketone: ropa, mweya, uye weti. Panzira nhatu idzi, ketoni dzeropa ndidzo dzakanyanyisa nekuti dzinomiririra izvo muviri wako uri kushanda nazvo.

Miyedzo yeweti inongobatsira mumatanho ekutanga e-keto-adaptation kana muviri wako uchiri kudzidza mashandisiro emaketoni auri kugadzira. Munguva ino, chikamu chakanaka chemaketoni aunoburitsa chinobuda nemuweti yako. Izvi zvinogona kukupa pfungwa yekuti muviri wako uri kugadzira ketoni here. Nekudaro, nekufamba kwenguva, muviri wako unowedzera kuchinjika uye huwandu hweketoni hwakarasika muweti huchadzikira.

Bvunzo dzekufema inzira yekuyedza uye haina kunyanya kupindira pane kuongororwa ropa, asi inogona kunge isina kunyatsojeka.

Chero nzira, kuziva mazinga ako eketone inzira yakanaka yekuona kana kudya kwako uye mararamiro ekuchinja ari kushanda.

Pane nzira dzinoverengeka dzekuyedza muviri wako kune ketoni. Unogona kuongororwa murabhoritari, asi kune dzimwe nzira dzinokurumidza uye dzinodhura.

Matanho ako eketone anogona kubva pazero kuenda pa3 kana kukwira, uye anoyerwa nemamillimoles parita (mmol/L). Pazasi pane huwandu hwakajairwa, asi ramba uchifunga kuti bvunzo mhinduro dzinogona kusiyana, zvichienderana nekudya kwako, nhanho yekuita, uye kuti wanga uri mu ketosis kwenguva yakareba sei.

• Negative ketone level: isingasviki 0,6 mmol.
• Yakaderera kusvika pakati nepakati ketone level: pakati pe0,6 ne1,5 mmol.
• Yakakwira mwero wemaketone: 1.6 kusvika 3.0 mmol.
• Yakanyanya kukwirira ketone level: inopfuura 3.0 mmol.

Zvino izvo mazinga atsanangurwa, ngatiendei pamusoro peakasiyana nzira dzekuyedza uye zvakanakira nezvazvakaipira zveimwe neimwe:

Urinalysis

Method: Weti pane weti strip, iyo inoratidza mwero wemaketone neruvara.

Zvakanakira: Unogona kutenga mitsetse muzvitoro zvakawanda zvezvinodhaka kana online nemutengo wakaderera kwazvo. Iyi isarudzo inokwanisika uye iri nyore kune mumwe munhu mutsva kune ketogenic kudya.

Cons: Urine test strips haina kuvimbika kwenguva yakareba iwe uri mu ketosis. Izvi zvinowanzoitika nekuti kana munhu ari muketosis, muviri unowedzera kushanda nesimba pakushandisa ketoni (kunyanya acetoacetate) yesimba. Naizvozvo, zvinogoneka kuti bvunzo inogona kuratidza yakaderera mwero weketosis pane zvaunowana chaizvo. Uyezve, weti ketone kuverenga kunogona kukanganiswa nezvimwe zvinhu, kusanganisira mwero we electrolytes mumuviri wako kana kuti iwe uri hydrated sei.

Blood bvunzo

Nzira: Nemamita eglucose yeropa, peni ye lancet inoshandiswa kudzvanya pamuromo wemunwe wako uye kutora sampuli diki yeropa. Ropa rinoiswa pa test strip rinotarisa mazinga eropa ketone kuburikidza nemamita.

Pros: Iyi inzira chaiyo yekutarisa ketoni sezvo zvishoma zvinhu zvinoshandura mhedzisiro.

Cons: Inogona kudhura, kunyanya kana iwe ukaedza kazhinji. Mutengo wacho unowanzo € 5-10 per strip!

Cherechedza: BHB ketone inotakurwa kuburikidza neropa, saka iyi ndiyo nzira yakanakisisa yekucherechedza mazinga ako eiyo ketone chaiyo.

kufema miedzo

Method: Shandisa Ketonix kufema mita kuti uedze huwandu hweacetone huripo mukufema kwako.

Zvakanakira: Inokwanisika kana watenga mita. Kana uchinge wazvitenga, unogona kuishandisa nguva dzose pasina mari yekuwedzera.

Cons: Haisi iyo yakavimbika nzira yekuyedza, saka inonyanya kushandiswa pamwe chete nedzimwe nzira.

ketoni uye kudya

Kana zvasvika padanho rakakodzera rekudya ketosis uye ketoni mumuviri, yakakodzera ketogenic kudya kwakakosha. Kune vanhu vazhinji, zvinoreva kudya pakati pe20-50 magiramu emacarbohydrates pazuva.

Kuita izvi kunoreva kuderedza kana kubvisa zvachose zvitubu zvecarbohydrates mukudya kwako, kusanganisira:

• Mbeu dzakakwana uye dzakagadzirwa.
• Candies uye zvakabikwa zvinhu.
• Zvinwiwa zvemichero uye zvinwiwa zvine shuga.
• Shuga dzakanatswa.
• Zvibereko.
• Nyeredzi dzakadai mbatatisi, chingwa, uye pasta.
• Bhinzi nenyemba.

Mukuwedzera pakucheka carbs, ketone-yakatarisana nekudya inosanganisira kudya zvine mwero zveprotein uye, zvinonyanya kukosha, huwandu hwakawanda hwemafuta kukurumidza kupisa mafuta.

Ketone Side Effects

Kune avo vari kungotanga kudya kwe ketogenic, pane zvinokwanisika zvenguva pfupi migumisiro yaunogona kuwana mukati mevhiki yekutanga kana zvakadaro. Izvi zvinokonzerwa neshanduko inoitika mumetabolism yako, iyo inogona kutonga kunze kwemamwe maitiro mumuviri wako.

Chimwe chezvikonzero zvikuru zveketo-adaptation zviratidzo imvura uye kurasikirwa kwe electrolyte. Kana muviri wako uchichinjira kumafuta ekupisa modhi, inoguma yarasikirwa nemvura yakawanda uye electrolytes pamwe chete nayo.

Zviratidzo zvinogona kusiyana zvakanyanya zvichienderana nemunhu, uye vamwe vanhu vanogona kunge vasina zvachose.

Kwenguva pfupi ketosis inogona kusanganisira:

• kunzwa kupera simba
• Kutemwa nemusoro
• Kunzwa "makore" mupfungwa.
• Kuneta kana kushatirwa.
• Flu-like zviratidzo.

Neraki, mhedzisiro ndeyenguva pfupi uye nyore nekukurumidza sezvo muviri uchichinjika kune shanduko yekudya kwemafuta sosi nekufamba kwenguva.

Ketone Level Yambiro

Vanhu vane Type 1 uye Type 2 chirwere cheshuga vanofanirwa kuziva nezvechirwere cheshuga ketoacidosis (DKA), chinoshandura ropa rive acidic kana ketoni dzichikwira kusvika padanho repamusoro.

Izvi zvinonyanya kukosha kune vanhu vane Type 1 chirwere cheshuga, sezvo DKA inowanzova mugumisiro wekushomeka kwe insulini kana kupotsa jekiseni re insulin.

DKA inogona kutyisidzira hupenyu, saka kana uine chirwere cheshuga, haufanirwe kutanga kudya uku pasina kutarisirwa nachiremba. Izvi zvinogona kuitika kune vane chirwere cheshuga vakakuvara, vanorwara, kana vasingatore mvura yakakwana.

Zvakakoshawo kuziva kuti DKA yakasiyana nekudya ketosis, iyo yakachengeteka pakudya kune hutano uye kunovaka muviri ketogenic. Kune vanhu vakawanda, hapanofanira kuva nehanya nekugadzirwa kweketone, sezvo ketoni inoshandiswa kana kubviswa kubva mumuviri uye inhengo yehutano hwehutano uye kupisa mafuta.

Ketoni inogona kuita basa rinobatsira zvikuru mune zvakawanda zvehupenyu, kusanganisira hutano huzhinji, kuora muviri, kushandiswa kwesimba, uye kuchengetedza hutano hwekudya ketogenic.

Kunzwisisa zvakadzama nezve ketoni uye kuti inokwana sei muchikamu che ketosis uye yakaderera-carb yekudya ndiyo kiyi yekubudirira munzvimbo dzese idzi dzakabatanidzwa.
