Pali njira ziwiri zoyang'ana ketoni. Pano, timakhudzidwa ndi maketoni ena (otchedwanso matupi a ketone) m'thupi la munthu, koma pa mbiri, ketone ndi gulu lokhala ndi gulu la carbonyl lomwe limagwira magulu awiri a atomu.
Pali ketoni zingapo m'thupi la munthu, koma zomwe timakhala nazo zimayambitsa chiwindi pamene timagwiritsa ntchito mafuta omwe timadya, kapena ngati timagwiritsa ntchito mafuta osungidwa.
Ketoni ingagwiritsidwe ntchito ndi maselo ochulukirapo m'thupi. Chochititsa chidwi, ubongo ukhoza kugwiritsa ntchito ketoni pafupifupi 70 mpaka 75% mwazofuna zake zamagetsi. Mankhwala a Ketoni amatha kupangidwa pazifukwa zina:
- Zakudya Zamadzimadzi / Ketogenic Zakudya kumene thupi liyenera kudalira mafuta a mphamvu
- Njala kapena kusala kudya ("zakudya zochepa")
- Zinthu zomwe zimapezeka m'thupi, koma thupi silingathe kugwiritsa ntchito shuga, kawirikawiri chifukwa cha kusowa kwa insulini mu Mtundu 1 (ndipo, kawirikawiri, mtundu wa 2) shuga.
Nthaŵi zambiri, matupi athu ali ndi njira zothandizira ma ketone kuti asafike pangozi, koma mathero otsiriza - "insulini" - amalola makononi a ketone kukwera mmwamba ku chiopsezo chotchedwa "diabetic ketoacidosis". Izi sizikuchitika pamene ketoni imakwezedwa chifukwa cha zowonjezera zakudya zokha.
Makhalidwe Achibadwa a Ketone
Kwa munthu amene amadya zakudya zowonjezera, zakudya zamakononi m'magazi zimakhala zochepa - pafupifupi 0.1 mmol / L (minimolars pa lita imodzi).
Titatha kuchita masewera olimbitsa thupi mwamsanga kapena titatha kuchita masewera olimbitsa thupi, timapeza kuti mlingo wafika pa 0.3 mmol / L.
Ngati palibe chakudya, kapena ngati tipewa zakudya m'thupi lathu, tidzakhala ndi maketoni ambiri pamene tikugwiritsa ntchito mafuta athu kuti tipeze mphamvu. Chakudya cha ketogenic chidzapangitsa chomwe chimatchedwa "ketosis", chomwe chiri pakati pa 0,5 mmol / L ndi 3 mmol / L, ngakhale kuti anthu ena amapeza kuti ali ndi magulu omwe ali apamwamba kwambiri.
Pa mlingo uwu, chilakolako chimachepa ndipo anthu ambiri amapeza kuti kuchepa kwa mafuta n'kosavuta.
Ngati munthu apitirira msanga kapena sangathe kupeza chakudya kwa milungu itatu kapena apo, mlingo wa ketone ukhoza kukwera pamwamba ngati 10 mmol / L. Ndipo vuto loopsa la ketoacidosis lingatumize makilomita 25 mmol / L kapena choncho.
Ubwino wa Ketoni
Sitikukayikira kuti panthawi ya kuchepa kwa chakudya, maketoni amachititsa anthu kukhala amoyo, pamene thupi silingathe kusunga shuga. Komabe, anthu amakhala ndi mafuta ochuluka omwe angagwiritsidwe ntchito monga masitolo ogwiritsira ntchito magetsi, ndipo matupi omwe sangathe kugwiritsa ntchito mwachindunji, monga ubongo, akhoza kugwiritsa ntchito ketoni mphamvu.
Kuonjezerapo, pali umboni wochuluka wosonyeza kuti ketoni ikhoza kukhala ndi zotsatira zabwino pamwamba komanso zopanda kuthandizira kupewa njala. Makamaka, pamene ubongo umagwiritsa ntchito ketoni mphamvu, ikhoza kukhala ndi chitetezo. Pakati pa zakudya zochepa zotchedwa carbohydrate ketogenic, nthawi zina dieters amawunika makina awo a ketone pogwiritsa ntchito mkodzo kapena kuyesera magazi.
