Kafukufuku wambiri akuwonetsa kuti kudya zakudya zokhala ndi shuga wambiri nthawi zonse kungayambitse kapena kudyetsa khansa. Kafukufuku wina akuwonetsanso kuti kudya shuga wambiri (kuchokera ku shuga wa beet) kumatha kusokoneza zotsatira za chithandizo chamtundu wina wa khansa. Gulu lofufuza lavumbulutsanso njira zama cell ndi njira zomwe zimagwirizanitsa kuchuluka kwa shuga m'magazi omwe amapezeka mwa odwala matenda ashuga kuti awonjezere kuwonongeka kwa DNA, popanga ma DNA adducts (kusintha kwamankhwala a DNA), komwe kumayambitsa masinthidwe, chomwe chimayambitsa khansa. Chifukwa chake, odwala khansa sayenera kudya shuga wambiri wokhazikika nthawi zonse. Komabe, kudula shuga kwathunthu kuchokera ku zakudya zathu si njira yothetsera chifukwa imasiya maselo athanzi opanda mphamvu! Kukhala ndi moyo wokhala ndi zakudya zopatsa thanzi ndikuchepetsa kudya shuga (mwachitsanzo: kuchokera ku beet ya shuga) komanso kuchita masewera olimbitsa thupi kungathandize kuchepetsa chiopsezo cha khansa kapena kusiya kudya. khansa.
“Kodi Shuga Amadyetsa Khansa?” “Kodi Shuga Angayambitse Khansa?” “Kodi ndiyenera kusiya kudya shuga kuti ndisiye kudya khansa?” “Kodi odwala khansa ayenera kupewa shuga?”
Awa ndi ena mwa mafunso omwe amafufuzidwa pafupipafupi pa intaneti kwa zaka zambiri. Nanga mayankho a mafunso amenewa ndi ati? Pali zambiri zotsutsana ndi nthano zokhudzana ndi shuga ndi khansa pagulu. Izi zimakhala nkhawa kwa odwala khansa ndi mabanja awo posankha zakudya za odwala. Mu blog iyi, tifotokoza mwachidule zomwe maphunzirowa akunena za kugwirizana pakati pa shuga ndi khansa ndi njira zophatikizira kuchuluka kwa shuga koyenera ngati gawo lazakudya zabwino.
Shuga ndi Khansa
Shuga amapezeka muzakudya zambiri zomwe timadya tsiku lililonse mwanjira ina. Sucrose ndi shuga wofala kwambiri womwe timakonda kuwonjezera pazakudya zathu monga shuga wapatebulo. Shuga wapa tebulo amasinthidwa kapena mtundu wosalala wa sucrose wotengedwa m'mapesi a nzimbe kapena beets. Sucrose imapezekanso muzakudya zina zachilengedwe kuphatikiza uchi, shuga wa mapulo ndi masiku koma imapezeka kuti imapezeka kwambiri munzimbe ndi muzitsamba za shuga. Zimapangidwa ndi glucose ndi fructose. Sucrose amakoma okoma kuposa shuga, koma osakoma kwambiri kuposa fructose. Fructose amadziwikanso kuti "shuga wa zipatso" ndipo amapezeka zipatso. Kuonjezera shuga wochuluka kwambiri wochotsedwa ku shuga kapena shuga ndikosavomerezeka.
Maselo m'thupi lathu amafunikira mphamvu kuti akule ndi kupulumuka. Glucose ndiye gwero lalikulu la mphamvu m'maselo athu. Zakudya zambiri zamadzimadzi ndi shuga zomwe timadya monga gawo la zakudya zathu zatsiku ndi tsiku monga chimanga ndi tirigu, ndiwo zamasamba, zipatso, mkaka ndi shuga wa patebulo (wotengedwa ku shuga beet) zimasweka kukhala shuga / shuga wamagazi mthupi lathu. Monga momwe khungu lathanzi limafunikira mphamvu kuti likule ndikukula, maselo a khansa omwe akukula mwachangu amafunanso mphamvu zambiri.
Maselo a khansa amachotsa mphamvu iyi m'magazi a shuga / shuga omwe amapangidwa kuchokera kuzakudya zama carbohydrate kapena zakudya zopatsa shuga. Kugwiritsa ntchito shuga kwambiri kwachuluka padziko lonse lapansi. Izi zimathandizira kwambiri kunenepa kwambiri komanso kunenepa kwambiri komwe kumatha kuyendetsa khansa. M'malo mwake, kunenepa kwambiri ndichimodzi mwazinthu zazikulu zomwe zimayambitsa khansa. Funso loti ngati shuga amadyetsa kapena amayambitsa khansa limachokera ku izi.
Kafukufuku / kusanthula kosiyanasiyana kwachitika ndi ofufuza padziko lonse lapansi kuti awone kuyanjana komwe kulipo pakati pa zakudya zopatsa thanzi kwambiri monga zakumwa zotsekemera komanso chiwopsezo cha khansa. Zotsatira zamaphunziro ambiriwa zalembedwa pansipa. Tiyeni tiwone zomwe akatswiri akunena!
Zakudya Zoti Mudye Mukatha Kuzindikira Khansa!
Palibe khansa ziwiri zomwezi. Pitani kupitilira malangizo omwe anthu onse amapereka kwa onse ndikupanga zisankho zomwe mungakonde pazakudya ndi zowonjezera ndi chidaliro.
Kodi kumwa zakumwa zosakaniza ndi zakumwa kungayambitse khansa / kudyetsa khansa?
Mgwirizano Wogwiritsira Ntchito Zakumwa Zosakaniza ndi Kuopsa kwa Khansa ya M'mawere
Kafukufuku waposachedwa wagwiritsa ntchito chidziwitso kuchokera ku French NutriNet-Santé cohort Study yomwe idaphatikizapo omwe akutenga nawo gawo 1,01,257 azaka zapakati pa 18 ndi kupitirira. Kafukufukuyu adawunika mgwirizano womwe ulipo pakati pa kumwa zakumwa zotsekemera monga shuga zotsekemera ndi timadziti ta zipatso za 100%, ndi zakumwa zotsekemera zokhazokha ndi khansa kutengera chidziwitso chazifunso. (Chazelas E et al, BMJ., 2019)
Kafukufukuyu adati omwe amamwa kwambiri zakumwa zotsekemera anali ndi mwayi wambiri wa 18% wokhala ndi khansa yonse ndipo 22% amatha kudwala khansa ya m'mawere poyerekeza ndi omwe samamwa kapena samakonda kumwa zakumwa zotsekemera. Komabe, ofufuzawo adalimbikitsa maphunziro omwe akuyembekezeka kuti akhazikitse mgwirizanowu.
Kafukufuku wofanananso adachitika omwe adasanthula deta kuchokera kwa azaka zapakati pa 10,713 azaka zapakati, azimayi aku Spain ochokera ku Seguimiento Universidad de Navarra (SUN) kafukufuku wamagulu azaka zapakati pa 33, omwe analibe mbiri ya khansa ya m'mawere. Kafukufukuyu adawunika kuyanjana pakati pakumwa zakumwa zotsekemera ndi shuga ndi vuto la khansa ya m'mawere. Pambuyo pakutsata kwazaka khumi, zochitika za 10 za khansa ya m'mawere zidanenedwa. (Romanos-Nanclares A et al, Eur J Nutr., 100)
Kafukufukuyu anapeza kuti poyerekeza ndi zero kapena zakumwa zoziziritsa kukhosi za shuga, kumwa zakumwa zotsekemera nthawi zonse kumatha kuphatikizidwa ndi vuto lalikulu la khansa ya m'mawere, makamaka azimayi omwe atha msinkhu. Anapezanso kuti panalibe mgwirizano pakati pa kumwa zakumwa zotsekemera ndi matenda a khansa ya m'mawere mwa amayi omwe sanatenge nthawi. Komabe, ofufuzawa apereka kafukufuku wamkulu wopangidwa bwino kuti athandizire izi. Mulimonsemo, ndibwino kuti odwala khansa azipewa kumwa zakumwa zotsekemera pafupipafupi.
Mgwirizano Wogwiritsira Ntchito Shuga Wotengeka Ndi Kuchuluka kwa Khansa ya Prostate
Kafukufuku waposachedwa adasanthula zambiri za amuna 22,720 ochokera ku Prostate, Lung, Colorectal, ndi Ovarian (PLCO) Cancer Screening Trial omwe adalembetsa pakati pa 1993-2001. Kafukufukuyu adawunika kuyanjana pakati pakumwa shuga wowonjezera kapena wakumwa mu zakumwa ndi ma dessert ndi prostate chiopsezo cha khansa. Pambuyo pakutsatiridwa kwapakatikati pazaka 9, amuna a 1996 adapezeka ndi khansa ya prostate. (Miles FL et al, Br J Nutriti., 2018)
Kafukufukuyu adawonetsa kuti kumwa shuga kwambiri kuchokera ku zakumwa zotsekemera kumalumikizidwa ndi chiopsezo chowonjezeka cha khansa ya prostate kwa amuna omwe amadya shuga wambiri. Kafukufukuyu adanenanso kuti kuchepetsa kumwa kwa zakumwa kungakhale kofunikira pochepetsa chiopsezo cha khansa ya prostate. Odwala khansa amafunika kupewa kudya kwambiri shuga wambiri.
Mgwirizano Wokumwa Zakumwa Zosakaniza ndi Khansa ya Pancreatic
Kafukufuku waposachedwa adawunikiranso zofananira pogwiritsa ntchito zidziwitso zochokera pamafunso ochokera kwa omwe akutenga nawo gawo pa 477,199 omwe adaphatikizidwa ku European Prospential Investigation of Cancer and Nutrition cohort Study, ambiri mwa iwo anali azimayi azaka zapakati pa 51. Pakutsatira zaka 11.6, khansa za pancreatic 865 zidanenedwa. (Navarrete-Muñoz EM et al, Am J Clin Nutr., 2016)
Mosiyana ndi kafukufuku wakale, kafukufukuyu adawonetsa kuti zakumwa zonse zotsekemera sizingagwirizane ndi chiopsezo cha khansa ya kapamba. Kafukufukuyu adapezanso kuti kumwa madzi ndi timadzi tokoma mwina kumatha kuchepa pang'ono ndi chiopsezo cha khansa ya kapamba. Odwala khansa ya Pancreatic amayenera kupewa kumwa kwambiri zakumwa ndi shuga wambiri.
Mgwirizano wamagulu a Shuga Wam'magazi Aakulu ndi Zotsatira Zakuchiritsa kwa Odwala Khansa Yoyenera
Pakafukufuku omwe ochita kafukufuku ku Taiwan adachita, adasanthula za 157 gawo lachitatu la odwala khansa amisala omwe adasankhidwa m'magulu awiri molingana ndi kusala kwawo kwa magazi - gulu limodzi lokhala ndi shuga m'magazi ⩾2 mg / dl ndipo lina ndi magazi shuga <126 mg / dl. Kafukufukuyu adayerekezera zomwe zidapulumuka komanso kutsutsana ndi chithandizo cha oxaliplatin m'magulu awiriwa. Anachitanso maphunziro a vitro kuti awone momwe mankhwala osokoneza bongo amakhudzira kuchuluka kwa khungu atapereka shuga. (Yang IP et al, Ther Adv Med Oncol., 126)
Kuphatikizanso kwa glucose kunachulukitsa kuchuluka kwa khungu la khansa mu vitro. Zikuwonetsanso kuti kuyang'anira mankhwala opatsirana ndi matenda ashuga omwe amatchedwa metformin atha kusinthitsa kuchuluka kwa maselo ndikuwonjezera mphamvu ya chithandizo cha oxaliplatin. Kafukufuku wamagulu awiri a odwala adati shuga wambiri m'magazi atha kuphatikizidwa ndi zomwe zimachitika kuti matenda abwererenso. Ananenanso kuti odwala omwe ali ndi khansa yosaoneka bwino ya siteji yachitatu komanso shuga wambiri wamagazi amatha kuwonetsa kuchepa kwamankhwala ndipo atha kukhala osagwirizana ndi mankhwala a oxaliplatin munthawi yochepa.
Zotsatira za kafukufukuyu zikusonyeza kuti shuga wambiri wamagazi amatha kukhudza zotsatira za mankhwala a oxaliplatin mwa odwala khansa ya Colorectal. Chifukwa chake, odwala khansa amisala omwe amalandira mankhwalawa amafunika kupewa kudya shuga wambiri.
Kodi pali mgwirizano uti pakati pa matenda ashuga ndi khansa?
Matenda a shuga ndi mliri wapadziko lonse wokhala ndi anthu opitilira 30 miliyoni aku America komanso anthu opitilira 400 miliyoni padziko lonse omwe akhudzidwa ndi matendawa. Malinga ndi bungwe la zamankhwala padziko lonse lapansi, kuchuluka kwa matenda ashuga kukukulirakulira mmaiko otsika mpaka kumayiko olemera, izi zikugwirizana ndi zakudya zopanda thanzi, kusachita masewera olimbitsa thupi komanso kunenepa kwambiri. Pakhala pali maphunziro angapo komanso kusanthula meta komwe kumawonetsa kulumikizana kwamphamvu pakati pa matenda ashuga komanso chiwopsezo chowonjezeka cha khansa, koma sizimadziwika bwinobwino chifukwa chake izi zili choncho. Dr. John Termini ndi gulu lake la City of Hope, bungwe lofufuza za khansa ku California, adasanthula bungweli ndipo adatha kulumikiza hyperglycemia (kuchuluka kwa shuga) ndi kuwonongeka kwa DNA, chomwe chimayambitsa kusintha kwa ziwalo zomwe zingayambitse khansa. Dr Termini adapereka zomwe adapeza chaka chatha pamsonkhano wapadziko lonse wa 2019 American Chemical Society.
Tisanalowe nawo mu chiwonetsero chodabwitsa ichi, tiyenera kumvetsetsa zofunikira ndi magwiridwe antchito kuti timvetsetse tanthauzo la kafukufuku wa Dr Termini. Monga anthu, timapeza mphamvu zomwe matupi athu amafunikira kuti azitha kudya, zomwe zikaphwanyidwa, zimatulutsa shuga kapena shuga wamagazi mthupi. Komabe, kuti thupi lithe shuga uyu kukhala mphamvu, imagwiritsa ntchito insulini, timadzi timene timapangidwa m'matumbo, kuti shuga atengeke ndimaselo ndi minyewa ya thupi. Anthu omwe amapezeka kuti ali ndi matenda a shuga amakhala ndi insulin m'munsi komanso mphamvu ya insulin m'thupi lawo, zomwe zimapangitsa kuti shuga azikhala m'mwazi, womwe umadziwika kuti hyperglycemia ndipo umatha kudzetsa mavuto ambiri azaumoyo. Lingaliro lina loti mumvetsetse ndikuti khansa imayamba chifukwa cha kusintha kwa maselo chifukwa cha kuwonongeka kwa DNA, komwe kumabweretsa magawo osalamulirika komanso osasunthika omwe amafalikira mthupi.
Mwachidule pazomwe Dr Termini adapeza komanso zomwe adalemba mu nkhani yolembedwa ndi ASCO (American Society of Clinical Oncology) Mtolankhani, a Caroline Helwick, Helwick alemba kuti Dr Termini ndi anzawo apeza kuti "kukwezedwa kwa glucose kumawonjezera kupezeka kwa ma DNA adducts - DNA yomwe ingakopeke kosatha ”Helwick C, ASCO Post, 2019). Gululo linapeza kuti kuchuluka kwa shuga m'magazi sikungangopanga kusintha kwa mankhwala a DNA (DNA Adducts) komanso kulepheretsa kukonzanso kwawo. Ma DNA adducts amatha kupangitsa kuti DNA isasokonezedwe panthawi yomwe imabwereza kapena kumasuliridwa kukhala mapuloteni (zomwe zimatsogolera ku kusintha kwa DNA), kapena kupangitsa kuti zingwe ziduke zomwe zimasokoneza kapangidwe kake ka DNA. Njira yokonzetsera DNA yomwe imayenera kukonza zolakwika zilizonse mu DNA panthawi yobwerezabwereza, imasokonezedwanso ndi mapangidwe a DNA adducts. Dr Termini ndi gulu lake azindikira zomwe adduct ndi mapuloteni omwe amakhudzidwa mwachindunji chifukwa cha kuchuluka kwa shuga m'magazi. Chidziwitso chodziwika bwino chinawonjezeka khansa Chiwopsezo cha odwala matenda a shuga chinali cholumikizidwa ndi kusokonezeka kwa mahomoni, koma kafukufuku wa Dr Termini akufotokoza momwe kusokonezeka kwa mahomoni kumabweretsa kusalinganika kwa shuga ndi kuchuluka kwa shuga / shuga m'magazi kumayambitsa kuwonongeka kwa DNA komwe kumawonjezera chiopsezo cha khansa kwa odwala matenda ashuga.
Gawo lotsatira, lomwe ofufuza osiyanasiyana ayamba kale kugwira ntchito, ndi momwe mungagwiritsire ntchito chidziwitsochi kuti muchepetse kwambiri khansa padziko lonse lapansi. "Mwachidziwitso, mankhwala omwe amachepetsa milingo ya glucose amathanso kuthandizira kuthana ndi khansa mwa" kufa ndi njala "maselo owopsa mpaka kufa" (Helwick C, ASCO Post, 2019). Termini ndi ofufuza ena ambiri akuwunika momwe anti-khansa imathandizira chifukwa cha mankhwala omwe amagwiritsidwa ntchito kwambiri a shuga omwe amatchedwa metformin, omwe amagwiritsidwa ntchito poyerekeza ndi kutsitsa shuga m'magazi. Kafukufuku wambiri woyesera m'mitundu yambiri ya khansa awonetsa kuti metformin imatha kuwongolera njira zama cell zomwe zimathandizira Kukonzanso kwa DNA.
Kodi maphunzirowa akuwonetsa chiyani- kodi shuga imayambitsa kapena kudyetsa khansa?
Pali zotsutsana zokhudzana ndi mgwirizano pakati pa kudya kwa shuga ndi chiopsezo cha khansa. Komabe, kafukufuku wambiri akuwonetsa kuti kumwa shuga m'miyeso yocheperako sikungayambitse / kudyetsa khansa. Kafukufukuyu akuwonetsanso kuti kudya zakudya zokhala ndi shuga wambiri nthawi zonse zomwe zimatha kuwonjezera kuchuluka kwa shuga m'magazi mpaka kufika pamlingo wapamwamba kwambiri zomwe zimapangitsa kuti munthu akhale wonenepa kwambiri komanso kunenepa kwambiri sikuli bwino ndipo kungayambitse matenda a khansa. Kudya pafupipafupi zakudya zotsekemera kwambiri (kuphatikiza shuga wa patebulo kuchokera ku beet) kungayambitse / kudyetsa khansa. Kafukufuku wina akuwonetsanso kuti kudya zakudya zokhala ndi shuga wambiri kumatha kusokoneza zotsatira zina zamankhwala mwachindunji khansa mitundu.
Kodi tiyenera kudula shuga kwathunthu pazakudya zathu kuti tipewe khansa?
Kudula mitundu yonse ya shuga kuchokera pachakudya sikungakhale njira yoyenera yopewera khansa, chifukwa maselo abwinobwino amafunikiranso mphamvu kuti zikule ndikukhala ndi moyo. Komabe, kuyang'anira zotsatirazi kungatithandizenso kukhala athanzi!
- Pewani kumwa zakumwa zotsekemera kwambiri zotsekemera, zakumwa zotsekemera, zakumwa zotsekemera kwambiri kuphatikiza timadziti ta zipatso ndikumwa madzi ambiri.
- Tengani shuga wokwanira ngati gawo la chakudya chathu pokhala ndi zipatso zathunthu m'malo mophatikiza shuga (wothira beet) kapena mitundu ina ya shuga ku zakudya zathu.
