Ketosis ndi mkhalidwe wa kagayidwe kachakudya komwe thupi limawotcha mafuta osungidwa kuti lipeze mphamvu ndipo ukutchuka kwambiri masiku ano. Anthu akugwiritsa ntchito njira zosiyanasiyana kuti akwaniritse ndikusunga mkhalidwewu, kuphatikizapo kutsatira zakudya za ketogenic, kusala kudya komanso kumwa zowonjezera. Mwa zowonjezera izi, ma ketone esters ndi ketone salts ndi zisankho ziwiri zodziwika bwino. Tiyeni tiphunzire zambiri za ma ketone esters ndi momwe amasiyanirana ndi ketone salts, sichoncho?
Kuti tidziwe kuti ma ketone esters ndi chiyani, choyamba tiyenera kudziwa kuti ma ketone ndi chiyani. Ma ketone nthawi zambiri ndi mafuta omwe amapangidwa ndi thupi lathu akamawotcha mafuta, ndiye ma ketone esters ndi chiyani? Ma ketone esters ndi matupi akunja a ketone omwe amalimbikitsa ketosis m'thupi. Thupi likadwala ketosis, chiwindi chimagawa mafuta kukhala matupi a ketone okhala ndi mphamvu zambiri, zomwe zimapatsa mphamvu maselo kudzera m'magazi. Mu zakudya zathu, maselo athu nthawi zambiri amagwiritsa ntchito shuga ngati mphamvu, yomwe shuga ndiye gwero lalikulu la mafuta m'thupi, koma popanda shuga, thupi limapanga ma ketone kudzera mu njira yotchedwa ketogenesis. Ma ketone bodies ndi gwero lamphamvu kwambiri kuposa shuga ndipo awonetsedwa kuti ali ndi maubwino ambiri azaumoyo.
Ma ketone bodies akunja amapangidwa ndi zigawo ziwiri zazikulu, ma ketone esters ndi mchere wa ketone. Ma ketone esters, omwe amadziwikanso kuti ketone monoesters, ndi mankhwala omwe amawonjezera kuchuluka kwa ma ketone m'magazi. Ndi ketone yakunja yomwe imapangidwa polumikiza thupi la ketone ku molekyulu ya mowa. Njirayi imapangitsa kuti ikhale yopezeka kwambiri, zomwe zikutanthauza kuti imayamwa mosavuta ndipo imakweza mwachangu kuchuluka kwa ma ketone m'magazi. Mchere wa ketone nthawi zambiri ndi ufa wokhala ndi BHB wolumikizidwa ku mchere wamchere (nthawi zambiri sodium, potaziyamu kapena calcium) kapena ma amino acid (monga lysine kapena arginine), mchere wa ketone wodziwika kwambiri ndi β-hydroxybutyrate (BHB) wolumikizidwa ku sodium, koma mchere wina wa potaziyamu ndi magnesium umapezekanso. Mchere wa ketone ukhoza kuwonjezera kuchuluka kwa BHB isoform m'magazi ya l-β-hydroxybutyrate (l-BHB).
Chifukwa chakuti ma ketone esters ndi mchere wa ketone ndi ma ketone akunja, izi zikutanthauza kuti amapangidwa mu vitro. Amatha kuwonjezera kuchuluka kwa ma ketone m'magazi, kupereka mphamvu, ndikuwonjezera magwiridwe antchito a ubongo. Angakuthandizeninso kulowa mu ketotic state mwachangu ndikusunga kwa nthawi yayitali. Ponena za kuchuluka kwa ma ketone m'magazi, ma ketone esters ndi zakumwa zopanda mchere za BHB popanda zigawo zina zowonjezera. Samalumikizana ndi mchere monga mchere wa BHB, koma m'malo mwake amalumikizana ndi ma ketone precursors (monga butanediol kapena glycerol) kudzera mu ma ester bonds, ndipo ma ketone esters amatha kuwonjezera d-β- Kuchuluka kwa magazi a BHB subtype ya hydroxybutyric acid (d-BHB) kumakhudzidwa mwachangu komanso mozama ndi ma ketone esters poyerekeza ndi mchere wa ketone.
1. Kuchita bwino kwa masewera
Chimodzi mwa zabwino kwambiri za ma ketone esters ndi kuthekera kwawo kukweza magwiridwe antchito amasewera. Izi zili choncho chifukwa ma ketone ndi gwero labwino kwambiri la mphamvu poyerekeza ndi shuga, yomwe ndi gwero lalikulu la mphamvu m'thupi. Pakuchita masewera olimbitsa thupi mwamphamvu, thupi limadalira shuga kuti lipange mphamvu, koma kuchuluka kochepa kwa shuga m'thupi kumachepa mwachangu, zomwe zimapangitsa kuti thupi lizitopa komanso lizigwira ntchito mochepa. Ma ketone esters amapereka mphamvu yokonzeka, zomwe zimapangitsa kuti othamanga azikankhira malire awo popanda kutopa komwe kumachitika akamadalira shuga wokha.
2. Zimathandiza kuti ubongo ugwire bwino ntchito
Ubwino wina wodabwitsa wa ma ketone esters ndi kuthekera kwawo kukonza magwiridwe antchito a ubongo. Ubongo ndi chiwalo chomwe chimagwiritsa ntchito mphamvu zambiri chomwe chimafuna shuga wokwanira kuti chigwire bwino ntchito. Komabe, ma ketones nawonso ndi gwero lamphamvu la ubongo, ndipo kafukufuku wasonyeza kuti ubongo ukakhala ndi mphamvu ndi ma ketones, umatha kugwira ntchito bwino kuposa pamene umadalira shuga wokha. Ichi ndichifukwa chake ma ketone esters awonetsedwa kuti akuwongolera magwiridwe antchito a ubongo, kukumbukira ndi kusamala, zomwe zimapangitsa kuti akhale njira yokopa kwa iwo omwe akufuna kukulitsa magwiridwe antchito a ubongo.
3. Zimathandiza kuchepetsa thupi
Pomaliza, ma ketone esters amathandizanso kuchepetsa thupi. Thupi likamadwala ketosis (mwachitsanzo, likalandira mphamvu kuchokera ku ma ketone), limawotcha mafuta bwino kwambiri kuposa shuga kuti likhale ndi mphamvu. Izi zikutanthauza kuti thupi limatha kutentha mafuta osungidwa kuti likhale mafuta, zomwe zimapangitsa kuti thupi lichepetse thupi. Kuphatikiza apo, ma ketone angathandize kuchepetsa chilakolako cha chakudya, zomwe zimapangitsa kuti anthu azidya zakudya zochepa zama calories ndikuchepetsa thupi bwino.
● Kuti tidziwe ngati ma ketone esters angathandize kuchepetsa thupi, choyamba tiyenera kumvetsetsa zomwe ma ketone esters ali. Ma ketone esters ndi mankhwala opangidwa omwe ali ndi ma ketone omwe amalowetsedwa mosavuta ndi thupi la munthu, zomwe zimapangitsa kuti akhale gwero labwino kwambiri la mafuta. Tikakhala mu mkhalidwe wa ketotic, ma ketone ndi gwero la mphamvu lopangidwa ndi thupi lathu. Izi zimachitika pamene shuga m'magazi ndi wochepa, ndipo thupi limayamba kuswa mafuta osungidwa kuti lipange ma ketone kuti lipereke mphamvu.
● Ofufuza asonyeza kuti othamanga omwe amamwa ma ester a Ketone ngati zowonjezera amakula bwino akamachita masewera olimbitsa thupi mwamphamvu. Kafukufuku waposachedwapa adapeza kuti ma ester a ketone amatha kusintha magwiridwe antchito a othamanga njinga apamwamba ndi pafupifupi 2%. Koma kodi izi zikutanthauza kuti anthu wamba amachepetsa thupi? Yankho lake mwina ndi lakuti. Kafukufuku wasonyeza kuti ma ester a ketone amatha kuletsa chilakolako cha chakudya, zomwe zimapangitsa kuti munthu achepetse kudya ma calories komanso kuti achepetse thupi. Komabe, kafukufuku wowonjezereka akufunika kuti adziwe ngati izi ndizokwanira kukhudza zotsatira zonse za kuchepa thupi.
●Kuphatikiza apo, ma ketone esters amathanso kuwonjezera kupanga kwa mahomoni otchedwa leptin. Leptin imagwira ntchito yofunika kwambiri pakulamulira chilakolako cha chakudya, kagayidwe kachakudya, komanso kugwiritsa ntchito mphamvu. Kuchuluka kwa leptin m'thupi kumatha kuchepetsa chilakolako cha chakudya ndikuthandizira kuchepetsa kudya konse.
● Kuwonjezera pa kuchepetsa chilakolako cha chakudya, kugwiritsa ntchito ma ketone esters kungayambitsenso kuwonjezeka kwa mphamvu ndi kagayidwe kachakudya m'thupi. Izi zipangitsa kuti munthu azigwiritsa ntchito kwambiri ma calories komanso kugwiritsa ntchito bwino mafuta osungidwa kuti apeze mphamvu. Izi, pamodzi ndi kuthekera kochepetsa chilakolako cha chakudya, zingathandize kupanga kusowa kwa ma calories ofunikira kuti munthu achepetse thupi.
●Komabe, kumbukirani kuti ma ketone esters si mankhwala ochizira kunenepa. Zakudya zabwino komanso kuchita masewera olimbitsa thupi nthawi zonse ndi njira zabwino kwambiri zochepetsera thupi. Ma ketone esters angagwiritsidwe ntchito ngati chowonjezera, osati njira yokhayo yochepetsera thupi.
●Mwachidule, ma ketone esters angakhale ndi ubwino wina wochepetsa thupi, koma kugwira ntchito kwawo kukufunikabe kafukufuku wowonjezereka. Angathandize kuchepetsa chilakolako cha chakudya, kupanga ma calories osakwanira, ndikuwonjezera mphamvu, koma ayenera kugwiritsidwa ntchito mosamala osati ngati njira yokhayo yochepetsera thupi. Zakudya zabwino, kuchita masewera olimbitsa thupi nthawi zonse, komanso kukhala ndi moyo wabwino ndi njira zabwino kwambiri zopezera ndikusunga kulemera kwabwino.
Ketone ester imapezeka mu mawonekedwe amadzimadzi ndipo ingatengedwe pakamwa. Komabe, mukamagwiritsa ntchito ketone ester, ndikofunikira kutsatira malangizo a dokotala. Nthawi zambiri amalangizidwa kuyamba ndi mlingo wochepa ndikuwonjezera pang'onopang'ono mlingo mpaka zotsatira zomwe mukufuna zitakwaniritsidwa.
Ndikofunikanso kudziwa kuti ma ketone esters ayenera kugwiritsidwa ntchito limodzi ndi zakudya za ketogenic kuti apeze zotsatira zabwino. Zakudya za ketogenic ndi zakudya zokhala ndi mafuta ambiri, mapuloteni ochepa, komanso chakudya chochepa chomwe chimayika thupi mu mkhalidwe wa ketosis.
