Kumbali imodzi, mankhwala a soya amayamikiridwa kumlengalenga, kumbali ina, amanyozedwa kwambiri ndikuimbidwa mlandu woipa kwambiri. Mukayang'ana pazambiri zaumboni ndi kafukufuku (mwa anthu!), Zogulitsa za soya ndi zakudya zabwino zokhala ndi matani ambiri azaumoyo. M'chilimwe cha 2016, mwachitsanzo, zidawonetsedwa kuti kumwa nthawi zonse kwa soya kumatha kukhala ndi zotsatira zabwino pazakudya za anthu kuti chiopsezo cha matenda a shuga ndi matenda amtima.
Zogulitsa za soya zimateteza ku matenda a shuga ndi matenda ena ambiri osatha
Zogulitsa za soya monga mkaka wa soya, tofu, tofu burgers, ndi soya cream zakhala zikunyozedwa mopanda chilungamo. Chifukwa ngati mumapewa nthawi zonse, mumasiya zabwino zathanzi - monga momwe kafukufuku wambiri wasonyezera pakadali pano.
Makamaka, ma isoflavones omwe ali mu soya - zinthu zachiwiri zamafuta ochokera ku gulu la flavonoids - amanenedwa kuti ndi omwe amachititsa kuti soya azigwiritsa ntchito nthawi zonse. Mwachitsanzo, akuti soya amateteza ku zizindikiro za kusintha kwa msambo, dyslipidemia, osteoporosis, ndi mitundu yosiyanasiyana ya matenda aakulu a impso.
Kafukufuku wina adasindikizidwa mu Ogasiti 2016 mu nyuzipepala ya Endocrine Society, Journal of Clinical Endocrinology and Metabolism. M'menemo, asayansi ochokera ku yunivesite ya Kashan ya Medical Sciences ku Iran analemba kuti kumwa mankhwala a soya ndi koyeneranso kupewa matenda a shuga ndi matenda a mtima. Pakafukufuku wapano, zodzitetezerazi zidapezeka mwa azimayi achichepere omwe akudwala matenda otchedwa polycystic ovary syndrome (PCOS).
Kwa PCOS: Zogulitsa za soya zimachepetsa kukana kwa insulin
PCOS ndi matenda ofala kwambiri a mahomoni omwe amakhudza 5 mpaka 10 peresenti ya amayi a msinkhu wobereka. Mu PCOS, thumba losunga mazira limagwira ntchito pang'ono. Kuzungulira kosakhazikika, kuchuluka kwa testosterone, kunenepa kwambiri, kakulidwe ka tsitsi lachimuna (kuchuluka tsitsi m'thupi, kuthothoka tsitsi kumutu), komanso nthawi zambiri kusabereka. Inde, PCOS ndi chifukwa cha kusowa kwa mwana kosafunikira mu 70 peresenti ya amayi onse osabereka.
PCOS imawonekeranso pakuwonjezereka kwa matenda amtima komanso kukana insulini, komwe kumatha kukhala mtundu wa shuga wa 2. Kafukufuku wasonyeza kuti pafupifupi 40 peresenti ya amayi omwe ali ndi matenda a shuga a zaka zapakati pa 20 ndi 50 amadwala PCOS.
Asayansi aku Iran ozungulira Dr. Mehri Jamilian tsopano adafufuza amayi 70 omwe adapezeka ndi PCOS komanso momwe zakudya zokhala ndi soya zingakhudzire zizindikiro. Theka la amayiwa adapatsidwa ma soya isoflavones mu kuchuluka (50 mg) ofanana ndi omwe amapezeka mu 500 ml mkaka wa soya. Theka lina linalandira placebo.
Iwo adawona momwe zolembera zosiyanasiyana (mahomoni, kuchuluka kwa kutupa, milingo yosiyanasiyana ya kagayidwe kachakudya, komanso kuchuluka kwa kupsinjika kwa okosijeni) zidasinthira m'miyezi itatu ikubwerayi.
Soya amachepetsa insulini, cholesterol, ndi lipids m'magazi
Kuchuluka kwa insulin yozungulira ndi zizindikiro zina zomwe zimagwirizanitsidwa ndi insulin kukana kunachepa kwambiri mu gulu la soya poyerekeza ndi gulu la placebo. Miyezo ya testosterone, cholesterol (LDL), ndi triglycerides (mafuta amagazi) adagweranso m'gulu la soya, koma osati m'gulu la placebo. Chifukwa cha zotsatira zabwino pamilingo ya lipid m'magazi, akukhulupirira kuti soya sangateteze ku matenda a shuga komanso kuteteza dongosolo lamtima.
Kafukufuku wathu anapeza kuti amayi omwe ali ndi PCOS akhoza kupindula kwambiri nthawi zonse kuphatikizapo mankhwala a soya muzakudya zawo, "akuyamikira Dr. Zatollah Asemi wa ku Kashan University of Medical Sciences.
Choncho ofufuza aku Iran amatsimikizira phunziro lomwe linasindikizidwa mu American Journal of Clinical Nutrition mu 2008. Ngakhale apo, zinasonyezedwa kuti anthu anayamba kukhala ndi matenda a shuga a mtundu wa 2 nthawi zambiri amadya mankhwala a soya (makamaka mkaka wa soya) ndi nyemba zina.
Zogulitsa za soya ndizothandizanso pamtima
Ofufuza pa yunivesite ya Vanderbilt ku Nashville adawonetsa momwe kugwiritsira ntchito soya kumapindulitsa pa thanzi la mtima kumbuyo mu 2003. Panthawiyo, adapeza kuti soya amachepetsa bwino chiopsezo chokhala ndi matenda a mtima. Ndi vuto la mtima ili, ziwiya zabwino za coronary zimachepa ndipo chifukwa chake, zovuta zamtundu uliwonse monga kupweteka pachifuwa (angina pectoris), kulephera kwa mtima, kugunda kwamtima mpaka kugunda kwamtima, komanso kufa mwadzidzidzi kwa mtima kumachitika.
The Vanderbilt asayansi tsopano kuwunika deta ku Shanghai Women's Health Study, anthu ofotokoza anthu oyembekezera gulu kafukufuku (1997 mpaka 2000) ndi pafupifupi 75,000 anthu a zaka zapakati pa 40 ndi 70. Zinasonyezedwa kuti chiopsezo kudwala matenda a mtima, m'pamene zinachepa kwambiri soya mankhwala omwe ophunzira amadya.
Mu Januwale 2017, Yan et al. chinthu chofanana kwambiri mu European Journal of Preventive Cardiology, kutanthauza kuti ngozi zitatu zathanzi zitha kuchepetsedwa kwambiri ngati mumadya soya pafupipafupi. Pamenepa, munthu sangadwale matenda a mtima, sitiroko, ndi matenda a mtima.
Ngati soya, ndiye kugula organic soya
Mukamagula zinthu za soya, nthawi zonse muzikumbukira kuti mumangogula mankhwala a soya opangidwa kuchokera ku soya organic, apo ayi pali chiopsezo chachikulu kuti soya amasinthidwa chibadwa ndipo akumananso ndi mankhwala ophera udzu wambiri. Pakadali pano, soya wa organic akukulanso ku Europe, mwachitsanzo ku Germany, France, ndi Austria. Izi zimachepetsa chiopsezo cha kusakanikirana kwa soya ndi GM soya pambuyo pokolola.
