Momwe Zakudya Zimakhudzira Kagayidwe ka Metabolism
Zakudya ndi nthambi ya sayansi yomwe imaphunzira momwe chakudya ndi michere zimakhudzira thanzi ndi thanzi la thupi. Chimodzi mwazinthu zofunika kwambiri pazakudya ndi momwe zimakhudzira kagayidwe kachakudya. Kagayidwe kachakudya ndi gulu la njira zama biochemical zomwe zimachitika m'thupi kuti zipititse patsogolo moyo, kuphatikizapo kugawikana kwa chakudya kukhala mphamvu ndi zomangira maselo. M'nkhaniyi, tifufuza momwe zakudya zimakhudzira kagayidwe kachakudya komanso chifukwa chake kumvetsetsa izi ndikofunikira kwambiri pa thanzi lathu.
Kufotokozera Kagayidwe kachakudya
Kagayidwe kachakudya kamakhala ndi njira ziwiri zazikulu: anabolism ndi catabolism. Anabolism ndi njira yomwe thupi limapangira mamolekyu ovuta kuchokera ku osavuta, monga kupanga mapuloteni kuchokera ku amino acid. Mosiyana ndi zimenezi, catabolism ndi njira yomwe thupi limagawira mamolekyu ovuta kukhala osavuta omwe angagwiritsidwe ntchito popanga mphamvu, monga kugawikana kwa chakudya kukhala shuga.
Kagayidwe kachakudya ka thupi kamakhudzidwa ndi zinthu zambiri, kuphatikizapo zaka, jenda, majini, ndi zochita zolimbitsa thupi. Komabe, zakudya zimathandizanso kwambiri pakulamulira kagayidwe kachakudya. Zinthu zomwe timadya—monga chakudya, mapuloteni, mafuta, mavitamini, ndi mchere—zonse zimakhudza kwambiri momwe matupi athu amagwirira ntchito ndikugwiritsa ntchito mphamvu.
Chakudya ndi Kagayidwe kachakudya
Chakudya ndi gwero lalikulu la mphamvu m'thupi. Chimagawika kukhala shuga, yomwe ingagwiritsidwe ntchito ndi thupi ngati mafuta kapena kusungidwa ngati glycogen m'chiwindi ndi minofu. Glycemic index (GI) imayesa momwe chakudya chomwe chili mu chakudya chimakwezera shuga m'magazi mwachangu. Zakudya zomwe zili ndi GI yokwera, monga buledi woyera kapena zakumwa zotsekemera, zimakweza shuga m'magazi mwachangu, pomwe zakudya zomwe zili ndi GI yotsika, monga zipatso ndi ndiwo zamasamba, zimakweza shuga pang'onopang'ono komanso mosalekeza.
Kufunika kosankha chakudya choyenera sikunganyalanyazidwe. Kudya kwambiri chakudya chokhala ndi GI yambiri kungayambitse kukwera kwa shuga m'magazi, kutsatiridwa ndi kuchuluka kwa insulin. Izi zingayambitse kukana kwa insulin, chomwe ndi chinthu chachikulu chomwe chimayambitsa matenda a shuga amtundu wa 2. Mosiyana ndi zimenezi, kusankha chakudya chokhala ndi GI yochepa kungathandize kusunga shuga m'magazi kukhala wokhazikika komanso kukonza kagayidwe ka mafuta m'thupi, komwe ndikofunikira kwambiri pakuwongolera kulemera ndi thanzi la mtima.
Mapuloteni ndi Kagayidwe kachakudya
Mapuloteni amakhala ndi ma amino acid, omwe ndi ofunikira popanga ma enzyme, mahomoni, ndi mapangidwe osiyanasiyana m'thupi. Limodzi mwa ntchito zazikulu za mapuloteni mu kagayidwe kachakudya ndi kupanga ndi kusunga minofu ya minofu. Minofu imagwira ntchito kwambiri pa kagayidwe kachakudya kuposa mafuta, zomwe zikutanthauza kuti imawotcha ma calories ambiri ngakhale ikapuma. Chifukwa chake, kudya mapuloteni okwanira kungathandize kuwonjezera kuchuluka kwa kagayidwe kachakudya (BMR).
Mphamvu ya kutentha kwa chakudya (TEF) ndi mphamvu yofunikira kuti tigaye, kuyamwa, ndikugawa michere kuchokera muzakudya zomwe timadya. Mapuloteni ali ndi TEF yapamwamba kwambiri poyerekeza ndi chakudya ndi mafuta, zomwe zikutanthauza kuti matupi athu amawotcha ma calories ambiri kuti agwiritse ntchito. Ichi ndi chimodzi mwa zifukwa zomwe zakudya zokhala ndi mapuloteni ambiri nthawi zambiri zimagwirizanitsidwa ndi kuwonjezeka kwa BMR komanso kuchepetsa thupi moyenera.
Mafuta ndi Kagayidwe kachakudya
Mafuta nthawi zambiri amaonedwa kuti ndi abwino pankhani ya zakudya komanso thanzi, koma kwenikweni ndi gawo lofunikira kwambiri pakudya moyenera. Mafuta amafunika kuti mavitamini osungunuka m'mafuta monga A, D, E, ndi K azitha kuyamwa. Kuphatikiza apo, mafuta amathandiza pakupanga ma cell membranes ndi mahomoni.
Mafuta amakhudzanso kagayidwe kachakudya m'njira zosiyanasiyana. Mafuta okhuta ndi osinthika, omwe amapezeka kwambiri muzakudya zokonzedwa komanso zopanda thanzi, amatha kuwonjezera cholesterol ya LDL (yoyipa) m'magazi, zomwe zimagwirizanitsidwa ndi chiopsezo cha matenda amtima komanso kuchepa kwa insulin. Mosiyana ndi zimenezi, mafuta osakhuta ndi amitundu yambiri, monga omwe amapezeka mu nsomba, ma avocado, ndi mafuta a azitona, amatha kuthandizira thanzi la kagayidwe kachakudya mwa kuwonjezera cholesterol ya HDL (yabwino) ndikuchepetsa kutupa.
Ma Omega-3, mtundu wa polyunsaturated fatty acid yomwe imapezeka mu nsomba zonenepa ndi mbewu za fulakesi, imadziwikanso kuti ili ndi zotsatira zabwino pa kagayidwe kachakudya. Ma Omega-3 amatha kuwonjezera okosijeni wa mafuta, kusintha kagayidwe ka shuga m'thupi, ndikuchepetsa kutupa, zonse zomwe zimathandiza kuchepetsa kulemera ndi thanzi lonse.
Mavitamini ndi Mineral mu Metabolism
Kuwonjezera pa macronutrients (chakudya, mapuloteni, ndi mafuta), micronutrients monga mavitamini ndi mchere zimathandiza kwambiri pa kagayidwe kachakudya. Mavitamini ndi mchere ena ofunikira pa kagayidwe kachakudya ndi awa:
1. Vitamini B:
– Mavitamini B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), ndi B6 (pyridoxine) amagwira ntchito m'magawo osiyanasiyana a kagayidwe ka chakudya, mafuta, ndi mapuloteni. Amathandiza kusintha chakudya kukhala mphamvu yogwiritsidwa ntchito m'thupi.
2. Vitamini D:
Vitamini D si yofunikira pa thanzi la mafupa okha komanso imakhudzanso kukhudzidwa kwa insulin komanso kagayidwe ka shuga m'thupi.
3. Chitsulo:
– Iron imafunika popanga hemoglobin, puloteni yomwe imanyamula mpweya m'magazi. Kusowa kwa iron kungayambitse kuchepa kwa magazi m'thupi, zomwe zingachepetse mphamvu ya thupi yogwira ntchito komanso kusokoneza kagayidwe kachakudya m'thupi lonse.
4. Magnesium:
– Magnesium imagwira ntchito m'machitidwe opitilira 300 a enzyme, kuphatikizapo kupanga mphamvu kuchokera ku chakudya chomwe timadya. Kusowa kwa magnesium kumatha kusokoneza kagayidwe kachakudya ndikuyambitsa zizindikiro za kutopa.
Mmene Zakudya Zimakhudzira Kagayidwe ka Thupi
Zakudya zosiyanasiyana zaphunziridwa kuti zimvetsetse momwe zimakhudzira kagayidwe kachakudya m'thupi. Mwachitsanzo, zakudya zokhala ndi chakudya chochepa cha carb nthawi zambiri zimagwiritsidwa ntchito pochepetsa thupi chifukwa zimatha kuchepetsa kuchuluka kwa insulin ndikuwonjezera kukhuthala kwa mafuta. Komabe, zakudya izi ziyenera kutsatiridwa mosamala kuti zitsimikizire kuti mapuloteni okwanira komanso mafuta abwino amalowa m'thupi.
Kumbali ina, zakudya zokhala ndi mapuloteni ambiri nthawi zambiri zimakhala zothandiza pakuchepetsa thupi chifukwa cha kuchuluka kwa TEF komanso kusunga minofu. Komabe, ndikofunikira kuonetsetsa kuti kudya mapuloteni sikokwanira, chifukwa izi zitha kupangitsa impso kuvutika.
Zakudya zopanda mafuta ambiri zinali zodziwika kale pankhani yochepetsa thupi, koma kafukufuku waposachedwapa akusonyeza kuti ubwino wa mafuta ndi wofunika kwambiri kuposa kuchuluka. Kudya mafuta abwino monga omega-3s, komanso kupewa mafuta okhuta ndi mafuta okhuta, kumathandiza kwambiri pa thanzi la kagayidwe kachakudya m'thupi.
Mapeto
Sayansi ya zakudya imakhudza kwambiri kagayidwe kachakudya kudzera mu kumvetsetsa kwake momwe zigawo zosiyanasiyana za chakudya zimakhudzira njira zamagetsi m'thupi. Chidziwitso ichi n'chofunikira kwambiri popanga zakudya zomwe zimathandiza thanzi ndi thanzi la nthawi yayitali. Mwa kusankha zakudya zoyenera ndikumvetsetsa momwe zimakhudzira kagayidwe kachakudya, titha kukonza magwiridwe antchito a thupi ndikupewa matenda osiyanasiyana osatha. Kumvetsetsa bwino sayansi ya zakudya ndi kagayidwe kachakudya ndi gawo loyamba lopita ku moyo wokhazikika komanso wathanzi.
