Nthawi yotsiriza ndinalankhula pa BBC Radio London, mmodzi wa amuna mu situdiyo anandifunsa ngati mankhwala soya anali otetezeka, ndiyeno anaseka: "Sindikufuna kukula mabere amuna!". Anthu amandifunsa ngati soya ndi otetezeka kwa ana, kodi kusokoneza kugwira ntchito kwa chithokomiro, kodi ndi zoipa kumathandiza kuchepetsa chiwerengero cha nkhalango padziko lapansi, ndipo ena amaganiza kuti soya angayambitse khansa.
Soya wasanduka madzi amadzi: iwe uli nawo kapena wotsutsa. Kodi nyemba yaing'ono iyi ndi chiwanda chenicheni, kapena otsutsa a soya akugwiritsa ntchito nkhani zowopsa ndi sayansi yabodza kuti akwaniritse zofuna zawo? Ngati muyang'anitsitsa, zikuwoneka kuti ulusi wonse wa kampeni yotsutsa soya imatsogolera ku bungwe la America lotchedwa WAPF (Weston A Price Foundation).
Cholinga cha maziko ndikubwezeretsanso muzakudya zanyama zomwe, m'malingaliro awo, zimakhala ndi michere yambiri - makamaka, tikulankhula za mkaka wopanda pasteurized, "yaiwisi" ndi zopangidwa kuchokera pamenepo. WAPF imanena kuti mafuta ochuluka a nyama ndi gawo lofunika kwambiri la zakudya zathanzi, komanso kuti mafuta a nyama ndi mafuta a kolesterolini alibe chochita ndi chitukuko cha matenda a mtima ndi khansa. Iwo amanena kuti anthu odya zamasamba amakhala ndi moyo waufupi kusiyana ndi odya nyama, ndiponso kuti anthu adya mafuta ochuluka a nyama m’mbiri yonse. Zowona, izi zimabwera motsutsana kotheratu ndi zotsatira za kafukufuku wa mabungwe akuluakulu azaumoyo padziko lonse lapansi, kuphatikiza WHO (World Health Organisation), ADA (American Dietetic Association) ndi BMA (British Medical Association).
Bungwe la ku America ili likukhazikitsa chiphunzitso chake pa kafukufuku wokayikitsa mwasayansi kuti apititse patsogolo malingaliro ake, ndipo, mwatsoka, akhala ndi chiyambukiro champhamvu kwa ogula ambiri omwe tsopano akuwona soya ngati mtundu wa zakudya zowonongeka.
Bizinesi yonse ya soya idayamba ku New Zealand koyambirira kwa zaka za m'ma 90, pomwe loya wochita bwino kwambiri, Milionea Richard James, adapeza katswiri wazowopsa Mike Fitzpatrick ndikumufunsa kuti apeze zomwe zimapha zinkhwe zake zokongola zokha. Komabe, panthawiyo Fitzpatrick adapeza kuti chifukwa cha imfa ya mbalamezi ndi soya zomwe adadyetsedwa, ndipo kuyambira pamenepo adayamba kutsutsa kwambiri soya ngati chakudya cha anthu - ndipo izi ndizopanda pake, anthu akhala akudya soya. kwa zaka zoposa 3000. !
Nthawi ina ndinali ndi wailesi ku New Zealand ndi Mike Fitzpatrick, yemwe akuchita kampeni yotsutsa soya kumeneko. Anali waukali kwambiri moti mpaka anathetsa kusamutsidwa pasadakhale. Mwa njira, Fitzpatrick amathandizira WAFP (ndendende, membala wolemekezeka wa bungweli).
Winanso wochirikiza gulu limeneli anali Stephen Byrnes, amene anafalitsa nkhani m’magazini yotchedwa The Ecologist yofotokoza kuti kusadya zamasamba ndi moyo woipa umene umawononga chilengedwe. Ankadzitamandira chifukwa cha zakudya zake zokhala ndi mafuta ambiri a nyama komanso thanzi labwino. Zoona, mwatsoka, iye anafa ndi sitiroko pamene iye anali 42. Panali zoposa 40 zoonekeratu zosalondola pa mfundo ya sayansi m'nkhani ino, kuphatikizapo molakwika mwachindunji zotsatira za kafukufuku. Koma bwanji - pambuyo pa zonse, mkonzi wa magazini ino, Zach Goldsmith, mwamwayi, adakhalanso membala wolemekezeka wa bungwe la WAPF.
Kaaila Daniel, membala wa board of directors a WAPF, adalemba ngakhale buku lonse lomwe "likuwonetsa" soya - "The Complete History of Soy." Zikuwoneka kuti bungwe lonseli likuwononga nthawi yochuluka kumenyana ndi soya kusiyana ndi kulimbikitsa zomwe akuganiza kuti ndi zakudya zabwino (mkaka wopanda pasteurized, kirimu wowawasa, tchizi, mazira, chiwindi, etc.).
Chimodzi mwazovuta zazikulu za soya ndi zomwe zili mu phytoestrogens (amatchedwanso "mahomoni a zomera"), zomwe zimati zimatha kusokoneza chitukuko cha kugonana komanso kusokoneza kubereka ana. Ndikuganiza kuti ngati pali umboni wa izi, boma la UK likanaletsa kugwiritsa ntchito soya muzinthu za ana, kapena kufalitsa chidziwitso chochenjeza.
Koma palibe machenjezo otere omwe adaperekedwa ngakhale boma litalandira kafukufuku wamasamba 440 wokhudza momwe soya imakhudzira thanzi la munthu. Ndipo zonse chifukwa palibe umboni wapezeka kuti soya akhoza kuvulaza thanzi. Komanso, lipoti la Department of Health Toxicology Committee likuvomereza kuti palibe umboni womwe wapezeka kuti mayiko omwe amadya soya nthawi zonse komanso mochuluka (monga a China ndi Japan) amavutika ndi vuto la kutha msinkhu komanso kuchepa kwa chonde. Koma tiyenera kukumbukira kuti China lero ndi dziko lokhala ndi anthu ambiri, lomwe lili ndi anthu 1,3 biliyoni, ndipo dziko lino lakhala likudya soya kwa zaka zoposa 3000.
M'malo mwake, palibe umboni wasayansi wosonyeza kuti kumwa soya kumawopseza anthu. Zambiri zomwe WAPF imati ndizopusa, sizowona, kapena zowona zozikidwa pa kuyesa kwa nyama. Muyenera kudziwa kuti ma phytoestrogens amachita mosiyana kwambiri ndi zamoyo zamitundu yosiyanasiyana ya zamoyo, kotero zotsatira za kuyesa nyama sizigwira ntchito kwa anthu. Kuonjezera apo, matumbo ndi chotchinga chachilengedwe kwa phytoestrogens, kotero zotsatira za zoyesera zomwe zinyama zimapangidwira ndi mlingo waukulu wa phytoestrogens sizothandiza. Kuphatikiza apo, pakuyesa kumeneku, nyama nthawi zambiri zimabayidwa jekeseni wa mahomoni ambewu omwe amakhala ochulukirapo kuposa omwe amalowa m'matupi a anthu omwe amadya soya.
Asayansi ndi madokotala ochulukirachulukira amazindikira kuti zotsatira za kuyesa kwa nyama sizingakhale maziko opangira ndondomeko yaumoyo wa anthu. Kenneth Satchell, pulofesa wa ana pachipatala cha ana ku Cincinnati, akunena kuti mu mbewa, makoswe ndi anyani, kuyamwa kwa soya isoflavones kumatsatira zochitika zosiyana kwambiri ndi za anthu, choncho deta yokha yomwe ingaganizidwe ndi yomwe imapezeka. kuchokera ku maphunziro a metabolic mwa ana. Oposa kotala la ana akhanda aku US adyetsedwa zakudya zopangidwa ndi soya kwa zaka zambiri. Ndipo tsopano, pamene ambiri a iwo ali kale zaka 30-40, amamva bwino. Kusapezeka kwa zotsatira zoyipa zilizonse za kumwa soya kungasonyeze kuti palibe.
Ndipotu soya ali ndi zakudya zosiyanasiyana zamtengo wapatali ndipo ndi gwero labwino kwambiri la mapuloteni. Umboni ukuwonetsa kuti mapuloteni a soya amachepetsa cholesterol ndikuletsa kukula kwa matenda amtima. Zopangidwa ndi soya zimalepheretsa kukula kwa matenda a shuga, kuchuluka kwa mahomoni panthawi yosiya kusamba, ndi mitundu ina ya khansa. Pali umboni wosonyeza kuti kumwa soya kwa achinyamata ndi akuluakulu kumachepetsa chiopsezo chokhala ndi khansa ya m'mawere. Kuphatikiza apo, kafukufuku waposachedwa akuwonetsa kuti phindu la soya limafikira kwa amayi omwe adapezeka kale ndi matendawa. Zakudya za soya zimathanso kusintha mafupa ndi malingaliro a anthu ena. Chiwerengero cha maphunziro a akatswiri m'madera osiyanasiyana omwe amatsimikizira ubwino wa soya pa thanzi la munthu akupitiriza kukula.
Monga mkangano wina, otsutsa soya amatchula mfundo yakuti kulima soya kumathandiza kuchepetsa nkhalango zamvula ku Amazon. Zoonadi, muyenera kudandaula za nkhalango, koma okonda soya alibe chochita: 80% ya soya zomwe zimabzalidwa padziko lapansi zimagwiritsidwa ntchito kudyetsa nyama - kuti anthu azidya nyama ndi mkaka. Nkhalango yamvula komanso thanzi lathu zingapindule kwambiri ngati anthu ambiri atasiya kudya zakudya zanyama kupita ku zakudya zokhala ndi zomera zomwe zimaphatikizapo soya.
Chifukwa chake nthawi ina mukamva nkhani zopusa za momwe soya amawonongera thanzi la munthu kapena chilengedwe, funsani umboniwo uli kuti.
