Kwa zaka makumi ambiri, manyuchi a chimanga cha fructose akhala akugwiritsidwa ntchito monga chotsekemera mu zakudya zopangidwa.

Chifukwa cha zomwe zili ndi fructose, zadzudzulidwa kwambiri chifukwa cha zovuta zomwe zingachitike chifukwa cha thanzi.

Anthu ambiri amati ndizovulaza kwambiri kuposa zotsekemera zina zopangidwa ndi shuga.

Nkhaniyi ikufanizira manyuchi a chimanga cha high-fructose ndi shuga wokhazikika, kuwunika ngati wina ali woyipa kuposa mnzake.

Kodi Fructose Chimanga Cham'madzi Ndi Chiyani?

Madzi a chimanga a High fructose (HFCS) ndi otsekemera ochokera ku chimanga, omwe amapangidwa kuchokera ku chimanga.

Amagwiritsidwa ntchito kutsekemera zakudya zopangidwa ndi zakumwa zozizilitsa kukhosi - makamaka ku United States.

Mofananamo ndi shuga wapa tebulo wamba (sucrose), amapangidwa ndi onse awiri a fructose ndi glucose.

Chinakhala chotsekemera chotchuka kumapeto kwa ma 1970 pomwe mtengo wa shuga wokhazikika unali wokwera, pomwe mitengo ya chimanga inali yotsika chifukwa chothandizidwa ndi boma (1).

Ngakhale kugwiritsidwa ntchito kwake kudakulirakulira pakati pa 1975 ndi 1985, watsika pang'ono chifukwa cha kutchuka kwa zotsekemera zopangira (1).

Madzi a chimanga a high-fructose ndi otsekemera opangidwa ndi shuga, omwe amagwiritsidwa ntchito popanga zakudya ndi zakumwa ku United States. Monga shuga wamba, imakhala ndi shuga wosavuta shuga ndi fructose.

Njira Yopangira

Madzi a chimanga a fructose amapangidwa kuchokera ku chimanga (chimanga), chomwe nthawi zambiri chimasinthidwa (GMO).

Chimanga chimagulitsidwa koyamba kuti apange wowuma chimanga, chomwe chimakonzedwa mopitilira kuti apange madzi a chimanga ().

Madzi a chimanga amakhala ndi shuga. Kuti ikhale yotsekemera komanso yofanana ndi kukoma kwa shuga wamba (sucrose), shuga wina amasinthidwa kukhala fructose pogwiritsa ntchito michere.

Mitundu yosiyanasiyana ya madzi a chimanga a high-fructose (HFCS) amapereka magawo osiyanasiyana a fructose.

Mwachitsanzo, pomwe HFCS 90 - mawonekedwe okhazikika kwambiri - ali ndi 90% fructose, mtundu womwe umagwiritsidwa ntchito kwambiri, HFCS 55, uli ndi 55% fructose ndi 42% shuga.

HFCS 55 ndi yofanana ndi sucrose (shuga wapa tebulo wamba), womwe ndi 50% fructose ndi 50% shuga.

Madzi a chimanga a high-fructose amapangidwa kuchokera ku chimanga cha chimanga (chimanga), chomwe chimakonzedwanso kutulutsa madzi. Mtundu wofala kwambiri uli ndi chiŵerengero cha fructose-to-glucose chofanana ndi shuga patebulo.

Madzi a Chimanga a High-Fructose vs. Shuga Wokhazikika

Pali zosiyana zochepa chabe pakati pa HFCS 55 - mtundu wofala kwambiri wa madzi a chimanga a high-fructose - ndi shuga wamba.

Kusiyanitsa kwakukulu ndikuti madzi a chimanga a high-fructose ndi madzi - okhala ndi 24% yamadzi - pomwe shuga patebulo ndi youma komanso granulated.

Potengera kapangidwe ka mankhwala, fructose ndi glucose m'mazira a chimanga a high-fructose samangirizidwa pamodzi ngati shuga wapa tebulo (sucrose).

M'malo mwake, zimayandama mosiyana.

Kusiyanaku sikukhudza thanzi kapena thanzi.

M'magazi anu am'mimba, shuga amathyoledwa kukhala fructose ndi glucose - motero manyuchi a chimanga ndi shuga zimatha kuyang'ana chimodzimodzi.

Gram ya gramu, HFCS 55 ili ndi milingo yaying'ono kwambiri ya fructose kuposa shuga wamba. Kusiyanaku ndikochepa kwambiri ndipo sikofunikira kwenikweni pankhani yazaumoyo.

Zachidziwikire, ngati mungafananize shuga wamba wa tebulo ndi HFCS 90, yomwe imakhala ndi 90% fructose, shuga wokhazikika akhoza kukhala wofunika kwambiri, chifukwa kumwa kwambiri fructose kumatha kukhala kovulaza kwambiri.

Komabe, HFCS 90 imagwiritsidwa ntchito kawirikawiri - kenako pokhapokha pokhapokha chifukwa cha kutsekemera kwambiri ().

Madzi a chimanga a high-fructose ndi shuga wa patebulo (sucrose) ali ofanana. Kusiyanitsa kwakukulu ndikuti mamolekyulu a fructose ndi glucose amamangiriridwa pamodzi mu shuga wa patebulo.

Zotsatira pa Zaumoyo ndi Metabolism

Chifukwa chachikulu chomwe zotsekemera zopangira shuga sichili bwino ndi chifukwa cha kuchuluka kwa fructose komwe amapereka.

Chiwindi ndiye chiwalo chokhacho chomwe chimagwiritsa ntchito fructose mochulukira. Chiwindi chanu chikadzaza, chimasandutsa fructose kukhala mafuta ().

Ena mwa mafutawa amatha kukhala m'chiwindi chanu, zomwe zimapangitsa mafuta kukhala ndi chiwindi. Kugwiritsa ntchito kwambiri fructose kumalumikizidwanso ndi kukana kwa insulin, matenda amadzimadzi, kunenepa kwambiri, ndi mtundu wa 2 shuga (,,).

Madzi a chimanga a high-fructose ndi shuga wokhazikika amakhala ndi kufanana kofananira kwa fructose ndi glucose - ndi chiŵerengero cha pafupifupi 50:50.

Chifukwa chake, mungayembekezere kuti zovuta zazaumoyo ndizofanana - zomwe zatsimikizika kangapo.

Poyerekeza kuyerekezera kofanana kwa madzi a chimanga a high-fructose ndi shuga wokhazikika, kafukufuku akuwonetsa kuti palibe kusiyana pakumva kukhuta, kuyankha kwa insulin, milingo ya leptin, kapena zovuta pakulemera kwa thupi (,,, 11).

Chifukwa chake, shuga ndi manyuchi a chimanga a high-fructose ali ofanana ndendende ndi thanzi.

Kafukufuku wochuluka akuwonetsa kuti shuga ndi madzi a chimanga a high-fructose ali ndi zotsatira zofananira pa thanzi ndi kagayidwe kake. Zonsezi ndizovulaza zikawonongedwa mopitirira muyeso.

Shuga Wowonjezera Ndi Woipa - Zipatso Sizo

Ngakhale fructose yochulukirapo yochokera ku shuga wowonjezera siyabwino, simuyenera kupewa kudya zipatso.

Zipatso ndi zakudya zonse, zokhala ndi michere yambiri, michere, ndi ma antioxidants. Ndizovuta kwambiri kudya kwambiri fructose ngati mukungopeza kuchokera ku zipatso zonse ().

Zotsatira zoyipa za fructose zimangogwira ntchito shuga wambiri wowonjezera, womwe umakhala ndi chakudya chambiri, chakumadzulo.

Ngakhale zipatso zili m'gulu la zinthu zolemera zachilengedwe za fructose, zimalumikizidwa ndi maubwino azaumoyo. Zovuta zathanzi zimangolumikizidwa ndikudya mopitilira muyeso wa shuga wowonjezera.

Mfundo Yofunika Kwambiri

Mitundu yofala kwambiri ya manyuchi a chimanga cha-fructose, HFCS 55, ndi ofanana ndi shuga wapa tebulo wamba.

Umboni wosonyeza kuti wina ndi woipa kuposa winayo ukusowa.

Mwanjira ina, onsewo ndi oyipa mofananamo akagwiritsidwa ntchito mopitirira muyeso.
