Odwala omwe ali ndi matenda ashuga, shuga amasinthidwa ndi fructose, yomwe ndi monosaccharide. Imapezeka mwachilengedwe monga zipatso, zipatso ndi uchi. Mtundu wopanga wa fructose umapangidwa mu labotale.
Pogwiritsa ntchito fructose, mbale zimatha kupatsidwa kutsekemera ndikugwiritsa ntchito m'malo mwa shuga, zomwe ndizofunikira kwa odwala matenda ashuga omwe sangathe kugwiritsa ntchito shuga.
Monga gawo la sucrose (shuga) ndilofanana ndi fructose ndi glucose. Shuga mutatha kumwa amagawidwa m'magawo awiriwa.
Pambuyo pake, thupi limapaka michere iyi m'njira ziwiri zosiyanasiyana. Ndi imodzi, insulini iyenera kukhalapo kuti ipangitse kulowa kwake kulowa mu cell ndikosavuta, njira yachiwiri siyogwirizana ndi insulin, yomwe imafunikanso kwa odwala matenda ashuga.
Zomwe zimagwiritsidwa ntchito pa fructose
Chifukwa chiyani fructose ndibwino kwa odwala matenda ashuga? Izi zili motere:
- Kuti thupi lizitha kuyamwa fructose, insulin siyofunikira.
- Mu thupi la munthu, pafupifupi minofu yonse, kuti akapatsidwe mphamvu, idyani shuga monga gwero lake lalikulu.
- Glucose munthawi ya makutidwe ndi okosijeni amatulutsa mamolekyulu ofunikira kwambiri m'thupi - adenosine triphosphates.
- Koma sizichitika nthawi zonse. Fructose mu shuga imagwiritsidwa ntchito ndi thupi kupatsa mphamvu umuna.
- Ngati izi sizokwanira, abambo amakhala opanda ungwiro. Pachifukwa ichi, ogonana olimba, osati iwo okha, komanso amayi ayenera kudya zipatso zambiri, komanso uchi tsiku lililonse.
Magulu a metabolic a assimilation a fructose ndi thupi la munthu amachitika m'chiwindi, komwe glycogen imapangidwa kuchokera ku fructose. Katunduyu ndiye gwero lamphamvu, lomwe limagwiritsidwa ntchito kubwezeretsa zofuna za thupi.
Njira zachikhalidwe
Metabolism imagwira ntchito kokha pachiwindi, chifukwa chake, ngati chiwalochi sichili bwino, akatswiri amalangizidwa kuti achepetse kugwiritsa ntchito fructose.
Njira yopanga shuga kuchokera ku fructose m'chiwindi ndi yovuta, chifukwa mwayi wama cell a chiwindi (hepatocytes) ulibe malire (izi zikugwira ntchito kwa munthu wathanzi).
Komabe, fructose imasinthidwa mosavuta kukhala triglyceride. Kuwonetsedwa koyipa kumeneku kumatheka ndi kudya kwambiri zakudya zopatsa mphamvu mu fructose.
Ubwino wotsatira wa fructose ndikuti monosaccharide amapambana kwambiri poyerekeza ndi shuga ndi kutsekemera.
Kuti mupeze kutsekemera komweko, fructose ifunika nthawi 2 zochepa.
Anthu ena samachepetsa kuchuluka kwa fructose, zomwe zimapangitsa chizolowezi chanu kudya zakudya zomwe zimakoma kwambiri. Zotsatira zake, zopatsa mphamvu za zoterezi sizimachepa, koma zimawonjezeka.
Izi zimapangitsa mwayi waukulu wa fructose zovuta zake, titha kunena kuti ndizofunikira kwambiri kwa odwala matenda ashuga, omwe angayambitse kuwoneka kwamafuta owonjezera komanso njira zoyipa zotsutsana ndi shuga.
Kukhazikitsidwa kuti ma caries amakula chifukwa chogwira ntchito ya tizilombo tating'onoting'ono, zomwe sizingachitike popanda shuga.
Pachifukwachi, kuchepetsa kudya shuga wambiri kumatha kuchepetsa kuwola kwa mano.
Amadziwika kuti pakudya fructose, milandu ya caries inatsikira mpaka 20-30%. Kuphatikiza apo, mapangidwe otupa mumkamwa wamkamwa amachepetsedwa, ndipo izi zimachitika chifukwa simungadye osati shuga, monga fructose.
Chifukwa chake, kuphatikiza kwa fructose mu zakudya kumakhala ndi zabwino zochepa, zomwe zimangokhala pakuchepetsa kuchuluka kwa insulini yomwe ikufunika komanso kuchepetsa kupezeka kwa zovuta zamano, ndipo m'malo mwa shuga anthu amtundu wa 2 amakonda kugwiritsidwa ntchito ndi odwala.
Nthawi zosavomerezeka pakumwa fructose
Odwala omwe ali ndi matenda ashuga sayenera kuphatikizapo zakudya zawo zopanda malire, mutha kudya pang'ono. Mawuwa amachokera ku zochita za metabolic zomwe zimachitika m'chiwindi.
Phosphorylation ndi yofunika kwambiri, pambuyo pake fructose imagawidwa kukhala ma monosaccharides atatu, omwe kenako amasintha kukhala triglycerides ndi mafuta acids.
Ichi ndi chifukwa:
- Kuchulukitsa minofu ya adipose, zomwe zimatsogolera pakupanga kunenepa kwambiri.
- Kuphatikiza apo, triglycerides imachulukitsa kuchuluka kwa lipoproteins, komwe kumayambitsa atherosclerosis.
- Zadziwika kuti atherosulinosis imabweretsa zovuta monga kugunda kwa mtima komanso sitiroko.
- Tiyeneranso kudziwa kuti shuga mellitus imakhala chifukwa cha mtima wamatenda a mtima.
- Izi zimaphatikizidwanso ndi kupezeka kwa matenda ashuga othamanga, komanso zovuta zomwe tafotokozazi.
Chifukwa chake, pokhudzana ndi funso "kodi ndizotheka kugwiritsa ntchito fructose kwa odwala matenda ashuga", ndiye kuti chidwi chambiri chaperekedwa kwa iwo posachedwapa. Chomwe chimapangitsa izi zimachitika chifukwa cha kupendekeka kwa machitidwe a metabolic komanso zinthu zina zovuta.
Kwa odwala matenda a shuga, fructose imatembenuzidwa mwachangu kwa glucose, yomwe imafunikira kuti inshuwaransi ikonzedwe, iyenera kulandiridwa bwino ndi maselo (mwachitsanzo, mwa wodwala yemwe ali ndi matenda osokoneza bongo a digiri yachiwiri, njira yopangira insulin ndiyabwino, koma pali kupatuka mu receptors, motero, insulin ili ndi zofunika kuchita).
Ngati palibe ma pathologies a metabolism a carbohydrate, ndiye kuti fructose ili pafupi osasinthidwa kukhala glucose. Pachifukwa ichi, odwala matenda ashuga saloledwa kuti aphatikizire mankhwala a fructose muzakudya zawo.
Kuphatikiza apo, maselo omwe alibe mphamvu amatha kukhathamiritsa minofu ya adipose. Chodabwitsachi chimaphatikizidwa ndi kuthamanga kwamphamvu kwamphamvu. Pofuna kubwezeretsanso minofu ya adipose, monga lamulo, fructose imagwiritsidwa ntchito, yomwe imilowetsedwa ndi chakudya.
Mapangidwe a minofu ya adipose kuchokera ku fructose amachitika popanda kukhalapo kwa insulin, motero, kuchuluka kwa minofu ya adipose kumawonjezeka kwambiri ndikukhala kokulirapo kuposa poyamba.
Akatswiri akukhulupirira kuti kugwiritsa ntchito shuga ndizomwe zimapangitsa kunenepa kwambiri. Malingaliro otere ali ndi ufulu kukhala, popeza akhoza kufotokozedwa ndi mfundo zotsatirazi:
- fructose imathandizira kuti mapangidwe asipose apangidwe mosavuta, chifukwa njirayi sifunikira insulini;
- ndizovuta kwambiri kuchotsa minyewa ya adipose yomwe imapangidwa ndikudya fructose, chifukwa cha izi minofu ya adipose ya wodwalayo imakula nthawi zonse;
- fructose samapereka kumverera kwachisoni. Izi zimatengera kuchuluka kwa shuga m'magazi. Zotsatira zake, bwalo loipa limapangidwa - wodwalayo amadya kwambiri komanso chakudya, koma nthawi yomweyo amakhala ndi njala.
Tiyenera kukumbukira kuti odwala omwe ali ndi matenda osokoneza bongo, kuchuluka kwa mafuta kumakhala chifukwa chachikulu chotsitsa kuchepa kwa chidwi cha maselo a receptor kupita ku insulin.
Zotsatira zake, kudya fructose kumabweretsa kunenepa kwambiri, komwe kumayambitsa kuwonongeka mkati mwa matenda monga matenda ashuga, komabe, kuvulaza ndi mapindu a fructose ndimutu wanthawi zonse wokambirana.
Gastroenterologists ochokera ku America atsimikizira kuti fructose mu shuga angayambitse kusokonekera kwamatumbo, ndipo chifukwa chake, nthenda yovuta monga matumbo osavomerezeka imatha kuchitika.
Ndi matendawa, wodwalayo amakhala ndi nkhawa za kudzimbidwa, kenako. Kuphatikiza apo, ndi matenda amtunduwu, kupweteka pamimba kumatha kuchitika, kumatulutsa kulipo.
Izi zimakhudza mayamwidwe a zinthu zofunika kufufuza, pali njira yogaya. Kugwiritsa ntchito mayeso ena asayansi kumapangitsa kuti athe kuzindikira bwinobwino matendawa osakwiya.
Kuzindikira sikukutanthauza kusokonezeka kwa chimbudzi.
