Tiyeni tiphunzire za mafuta 'abwino' m'thupi. Kodi mafuta a bulauni ndi chiyani?

Tonsefe timaganiza kuti tikanena kuti "mafuta", amatanthauza chinthu chovulaza komanso chosafunikira m'thupi, eti? Izi ndi zoona tikamanena za mafuta omwe amasonkhana m'mimba ndi m'chiuno. Koma kodi mumadziwa kuti palinso mtundu wina wa mafuta 'abwino' womwe uli m'thupi mwathu, womwe umatithandiza? Ndiwo womwe timatcha "mafuta abulauni" kapena `(Mafuta abulauni)`. Kunena zoona, amatchedwanso `(Minofu ya Adipose ya Brown)`. Uwu ndi mtundu wapadera wa mafuta womwe umagwira ntchito ngati chotenthetsera pang'ono m'thupi lathu.

Kodi kusiyana pakati pa mafuta a bulauni ndi mafuta oyera ndi kotani?

Choncho kuti timvetse bwino izi, choyamba tiyenera kudziwa mitundu iwiri ikuluikulu ya mafuta m'thupi lathu.

1. Mafuta Oyera: Uwu ndi mtundu wa mafuta omwe tonse timawadziwa ndi kulankhula za iwo nthawi zonse. Tikamadya zakudya zopatsa mphamvu zambiri, kutanthauza kuti, zakudya zopatsa mphamvu zambiri, mphamvu yochulukirapo imasungidwa m'matupi athu ngati mafuta oyera. Thupi limasunga mphamvu mwanjira imeneyi kuti lizigwiritse ntchito pambuyo pake pamene palibe chakudya. Nthawi zambiri, izi zimasungidwa m'malo monga m'mimba, m'chiuno, ndi m'ntchafu. Komabe, kuchuluka kwa mafuta oyera awa, makamaka m'mimba, kumawonjezera kwambiri chiopsezo cha matenda monga matenda a mtima ndi matenda a shuga a mtundu wa 2 .

2. Mafuta a Brown: Uyu ndiye ngwazi ya nkhani yathu. Ntchito yayikulu ya mafuta a Brown si kusunga mphamvu, koma kutentha mphamvu ndikupatsa thupi kutentha komwe likufuna . Awiriwa amapangidwanso ndi zinthu zosiyanasiyana. Mafuta oyera amapangidwa ndi madontho akuluakulu a mafuta acid (lipids). Koma maselo amafuta a Brown amadzazidwa ndi mtundu wapadera wa organelle wotchedwa mitochondria .

Ganizirani za mitochondria ngati mainjini ang'onoang'ono mkati mwa maselo athu. Awa ndi maselo omwe amatenga shuga ndi mafuta omwe timadya ndikuwotcha kuti apange mphamvu. Mitochondria iyi ili ndi chitsulo chochuluka, ndichifukwa chake mafuta abulauni amadziwika ndi dzina lake komanso mtundu wake. Mafuta abulauni amathanso kusunga mphamvu zambiri pamalo ochepa kwambiri kuposa mafuta oyera.

Onani tebulo ili m'munsimu kuti mumvetse bwino kusiyana kumeneku.

Kodi mafuta a bulauni amenewa amagwira ntchito bwanji?

Iyi ndi njira yodabwitsa kwambiri. Tangoganizani kuti mukuzizira kwambiri. Kenako thupi lanu limayamba kunjenjemera, sichoncho? Kunjenjemera kumeneko ndiko kuyambitsa minofu ndi kupanga kutentha.

Koma taonani makanda aang'ono. Makanda obadwa kumene sangagwedezeke kuti adzitenthe ngati mmene ife tingachitire. Ndiye ndani amawateteza ku chimfine? Pamenepo ndi pomwe mafuta a bulauni amalowa. Ana akabadwa, amakhala ndi mafuta ambiri a bulauni omwe ali kumbuyo kwa mapewa awo ndi m'khosi mwawo.

Thupi lanu likazizira, ubongo wanu umatulutsa mahomoni otchedwa norepinephrine . Zili ngati uthenga woti, "Wazizira, funda!" Maselo amafuta a bulauni ali ndi ma receptors apadera omwe amatha kuzindikira mahomoni awa. Akalandira uthengawu, mitochondria mkati mwa maselo amafuta a bulauni imayaka moto, ndikuwotcha mphamvu mwachangu ndikupanga kutentha.

Pamene tikukula, pamene luso lathu loyenda likuwonjezeka, timataya mafuta ambiri a bulauni awa. Koma samatha kwathunthu. Ngakhale mwa akuluakulu, pali mafuta ochepa a bulauni omwe amatsala m'khosi, m'mapewa, pafupi ndi impso, komanso mozungulira msana. Kafukufuku wapeza kuti anthu omwe nthawi zambiri amakhala ochepa thupi komanso omwe ali ndi mafuta ochepa m'thupi amakhala ndi mafuta a bulauni ambiri, ndipo akazi amakhala ndi mafuta ochulukirapo pang'ono kuposa amuna .

Ubale pakati pa mafuta a bulauni ndi thanzi lathu

Tsopano asayansi akuchita kafukufuku wambiri pa ubwino wina wa mafuta a bulauni awa. Makamaka, ali ndi chidwi chofuna kudziwa ngati angagwiritsidwe ntchito ngati mankhwala ochizira kunenepa kwambiri. Chifukwa ngati mafuta a bulauni angagwiritse ntchito mafuta oyera ngati mafuta ndikuwotcha, zingakhale zothandiza kwambiri pakuchepetsa thupi.

Kafukufuku waposachedwapa adapeza chinthu chofunikira kwambiri. Ndiko kuti, mafuta a bulauni amatha kusefa ma amino acid ena m'magazi athu. Makamaka, ma amino acid a leucine, isoleucine, ndi valine . Timapeza izi kuchokera ku zinthu monga mazira, nyama, nsomba, ndi mkaka. Amapezekanso mu zowonjezera zomwe anthu ena amamwa kuti amange minofu. Pazochuluka zabwino, izi ndi zabwino kwa thupi. Koma kuchuluka kwa izi m'magazi kwalumikizidwa ndi kunenepa kwambiri ndi matenda a shuga.

Kafukufuku akuchitikanso kuti awone ngati mahomoni omwe amachititsa kuti mafuta a bulauni apangidwe panthawi yochita masewera olimbitsa thupi. Chiyembekezo ndi chakuti zonsezi zigwiritsa ntchito mphamvu zodabwitsa za mafuta a bulauni kuti apeze mankhwala ochizira kunenepa kwambiri mtsogolo.

Kodi mafuta a bulauni angagwiritsidwe ntchito pochepetsa thupi?

Ili ndi funso lomwe anthu ambiri ali nalo. Asayansi akuyesera kuwona ngati mankhwala angayambitse mafuta a bulauni popanda kuzizira. Ngati mankhwala oterewa angapezeke, kungakhale chiyambi cha njira yatsopano yochepetsera thupi.

Koma pali chiopsezo chochepa. Mafuta a bulauni akayamba kugwira ntchito ndipo mphamvu zimayaka, zimatha kuwonjezera kugunda kwa mtima ndi kuthamanga kwa magazi . Izi sizabwino kwa anthu omwe ali pachiwopsezo cha matenda a mtima. Chifukwa chake, kafukufuku wozama amafunika kuti adziwe momwe mankhwalawa alili otetezeka.

Choncho kumbukirani kuti izi zikadali mu gawo lofufuza. Ngati mukuganiza zochepetsa thupi, njira yabwino komanso yotetezeka pakali pano ndikudya zakudya zopatsa thanzi, kuchita masewera olimbitsa thupi nthawi zonse, komanso kufunsa upangiri woyenera kwa dokotala kapena dokotala wanu.
