Ngesikhathi sokugcina ngikhuluma ku-BBC Radio London, enye yamadoda e-studio yangibuza ukuthi imikhiqizo yesoya iphephile, wabe esehleka: "Angifuni ukukhula amabele wesilisa!". Abantu bayangibuza ukuthi i-soy iphephile yini ezinganeni, ingabe iphazamisa ukusebenza kwendlala yegilo, ingabe inomthelela omubi ekunciphiseni inani lamahlathi emhlabeni, futhi abanye baze bacabange ukuthi isobho lingabangela umdlavuza.
I-Soy isiphenduke indawo yamanzi: ungowayo noma uphikisana nayo. Ingabe lo bhontshisi omncane ngempela uyidemoni langempela, noma mhlawumbe abaphikisi besoya basebenzisa izindaba ezisabisayo kanye nesayensi-mbumbulu ukuze bafeze izithakazelo zabo? Uma ubhekisisa kahle, kuvele ukuthi yonke imicu yomkhankaso wokulwa nesoya iholela enhlanganweni yaseMelika ebizwa ngokuthi i-WAPF (Weston A Price Foundation).
Umgomo wesisekelo uwukubuyisela ekudleni imikhiqizo yezilwane, ngokombono wabo, egxile kwimisoco - ikakhulukazi, sikhuluma ngobisi olungaxutshiwe, "oluhlaza" kanye nemikhiqizo evela kulo. I-WAPF ithi amafutha ezilwane asuthisiwe ayingxenye ebalulekile yokudla okunempilo, nokuthi amafutha ezilwane kanye ne-cholesterol ephezulu akuhlangene nokukhula kwesifo senhliziyo nemithambo yegazi. Baphikisa ngokuthi abantu abadla imifino baphila isikhathi esifushane kunalabo abadla inyama, nokuthi isintu siye sadla amafutha ezilwane amaningi kuwo wonke umlando. Yiqiniso, lokhu kufika ngokungqubuzana ngokuphelele nemiphumela yocwaningo lwezinhlangano zezempilo ezihamba phambili emhlabeni, ezihlanganisa i-WHO (World Health Organization), ADA (American Dietetic Association) kanye ne-BMA (British Medical Association).
Le nhlangano yaseMelika isekela imfundiso yayo ocwaningweni olungabazisayo ngokwesayensi ukuze kuthuthukiswe eyayo imibono, futhi, ngeshwa, isivele ibe nomthelela omkhulu kubathengi abaningi manje asebebona isobho njengohlobo lokuxoshwa kokudla.
Lonke ibhizinisi le-soy laqala eNew Zealand ekuqaleni kwawo-90s, lapho ummeli ophumelele kakhulu, usozigidi uRichard James, ethola isazi se-toxicologist uMike Fitzpatrick futhi wamcela ukuba athole ukuthi yini eyayibulala ama-parrots akhe amahle akhethekile. Noma kunjalo, ngaleso sikhathi uFitzpatrick wafinyelela esiphethweni sokuthi imbangela yokufa kwama-parrots kwakuwubhontshisi ababewondliwa, futhi kusukela ngaleso sikhathi waqala ukuphikisa kakhulu ubhontshisi wesoya njengokudla kwabantu - futhi lokhu kuyimbudane, abantu bebelokhu bedla ubhontshisi. iminyaka engaphezu kuka-3000. !
Ngake ngaba nohlelo lomsakazo eNew Zealand noMike Fitzpatrick, okhankasela ukulwa nesoya lapho. Ubenolaka kangangokuthi kwaze kwadingeka ukuthi akuqedele ukudayiselana ngaphambi kwesikhathi. Ngendlela, uFitzpatrick usekela i-WAFP (ngokunembile, ilungu elihloniphekile lebhodi lale nhlangano).
Omunye umsekeli wale nhlangano kwakunguStephen Byrnes, owanyathelisa isihloko kumagazini i-Ecologist esasithi ukudla imifino kuyindlela yokuphila engenampilo elimaza indawo ezungezile. Waqhosha ngokudla kwakhe okunamafutha ezilwane amaningi kanye nempilo enhle. Yiqiniso, ngeshwa, wabulawa isifo sohlangothi lapho eneminyaka engu-42. Kwakukhona okungaphezu kuka-40 okungalungile okusobala ngokombono wesayensi kulesi sihloko, okuhlanganisa nokuhlanekezela okuqondile kwemiphumela yocwaningo. Kodwa kuthiwani - ngemva kwakho konke, umhleli wale magazini, u-Zach Goldsmith, ngenhlanhla, naye waba yilungu elihloniphekile lebhodi le-WAPF.
UKaaila Daniel, oyilungu lebhodi labaqondisi be-WAPF, waze wabhala incwadi yonke “edalula” isoyi - “Umlando Ophelele Wesoya.” Kubonakala sengathi le nhlangano yonke ichitha isikhathi esiningi ihlasela isoya kunokukhuthaza lokho abacabanga ukuthi kuwukudla okunempilo (ubisi olungaxutshiwe, ukhilimu omuncu, ushizi, amaqanda, isibindi, njll.).
Okunye okungalungile okuyinhloko kwe-soy okuqukethwe kwe-phytoestrogens (abuye abizwe ngokuthi "ama-hormone ezitshalo"), okusolwa ukuthi angaphazamisa ukuthuthukiswa kocansi futhi abe nomthelela omubi emandleni okuzala abantwana. Ngicabanga ukuthi uma bekunobufakazi balokhu, uhulumeni wase-UK ubengavimbela ukusetshenziswa kwe-soy emikhiqizweni yezingane, noma okungenani asakaze ulwazi oluyisixwayiso.
Kodwa azikho izexwayiso ezinjalo ezikhishwe ngisho nangemva kokuba uhulumeni ethole ucwaningo olungamakhasi angama-440 mayelana nokuthi isoyi iyithinta kanjani impilo yabantu. Futhi konke ngoba abukho ubufakazi obutholakele bokuthi i-soy ingalimaza impilo. Ngaphezu kwalokho, umbiko woMnyango Wezempilo Wezobuthi uyavuma ukuthi abukho ubufakazi obutholakele bokuthi amazwe adla ubhontshisi wesoya njalo futhi ngobuningi (njengamaShayina namaJapane) ahlushwa izinkinga zokuthomba nokuncipha kokuzala. Kodwa kufanele sikhumbule ukuthi i-China namuhla iyizwe elinabantu abaningi kakhulu, elinabantu abayizigidi eziyizinkulungwane ezingu-1,3, futhi lesi sizwe besilokhu sidla isobho iminyaka engaphezu kuka-3000.
Eqinisweni, abukho ubufakazi besayensi bokuthi ukusetshenziswa kwe-soy kubangela usongo kubantu. Okuningi kwalokho okushiwo yi-WAPF kuyinhlekisa, akulona iqiniso, noma amaqiniso asekelwe ekuhlolweni kwezilwane. Udinga ukwazi ukuthi i-phytoestrogens iziphatha ngendlela ehluke ngokuphelele ezintweni eziphilayo zezinhlobo ezahlukene zezinto eziphilayo, ngakho imiphumela yokuhlolwa kwezilwane ayisebenzi kubantu. Ngaphezu kwalokho, amathumbu ayisithiyo semvelo ku-phytoestrogens, ngakho-ke imiphumela yokuhlolwa lapho izilwane zijova ngokwenziwa ngemithamo emikhulu ye-phytoestrogens ayibalulekile. Ngaphezu kwalokho, kulokhu kuhlolwa, izilwane zivame ukujovwa ngemithamo yamahomoni ezitshalo aphakeme izikhathi eziningi kunalawo angena emizimbeni yabantu abadla imikhiqizo yesoya.
Ososayensi abaningi kanye nodokotela bayaqaphela ukuthi imiphumela yokuhlolwa kwezilwane ayikwazi ukuba yisisekelo sokwakhiwa kwenqubomgomo yezempilo yomphakathi. UKenneth Satchell, uprofesa wezifo zezingane esibhedlela Sezingane eCincinnati, uthi kumagundane, amagundane nezinkawu, ukumuncwa kwe-soy isoflavone kulandela isimo esihluke ngokuphelele kunabantu, ngakho-ke okuwukuphela kwemininingwane engacatshangelwa yileyo etholiwe. kusuka ezifundweni ze-metabolic ezinganeni. Ngaphezu kwengxenye yesine yezingane zase-US zondliwa ukudla okusekelwe ku-soy iminyaka eminingi. Futhi manje, lapho abaningi babo sebeneminyaka engama-30-40 ubudala, bazizwa bejabule. Ukungabikho kwanoma yimiphi imiphumela emibi ebikiwe yokusetshenziswa kwe-soy kungase kubonise ukuthi ayikho.
Eqinisweni, ubhontshisi wesoya unezinhlobonhlobo eziningi zezakhi ezibalulekile futhi awumthombo omuhle kakhulu wamaprotheni. Ubufakazi bubonisa ukuthi amaprotheni e-soy anciphisa amazinga e-cholesterol futhi avimbele ukuthuthukiswa kwesifo senhliziyo. Imikhiqizo esekelwe ku-soy ivimbela ukukhula kwesifo sikashukela, ukukhuphuka kwama-hormone ngesikhathi sokuya esikhathini, kanye nezinhlobo ezithile zomdlavuza. Kunobufakazi bokuthi ukusetshenziswa kwemikhiqizo yesoya entsheni nakubantu abadala kunciphisa ingozi yokuba nomdlavuza webele. Ngaphezu kwalokho, ucwaningo lwakamuva lukhombisa ukuthi lo mphumela onenzuzo wesoya udlulela kwabesifazane asebetholwe benalesi simo. Ukudla kwe-soy nakho kungathuthukisa amathambo nokusebenza kwengqondo kwabanye abantu. Inani lezifundo zochwepheshe emikhakheni ehlukahlukene eziqinisekisa imiphumela enenzuzo yesoya empilweni yomuntu iyaqhubeka nokukhula.
Njengenye ingxabano, abamelene nesoya bacaphuna iqiniso lokuthi ukutshalwa kukabhontshisi wesoya kunomthelela ekuncishisweni kwamahlathi emvula e-Amazon. Yiqiniso, kufanele ukhathazeke ngamahlathi, kodwa abathandi be-soy abahlangene nakho: u-80% wamabhontshisi e-soya atshalwa emhlabeni asetshenziselwa ukupha izilwane - ukuze abantu badle inyama nemikhiqizo yobisi. Kokubili ihlathi lemvula nempilo yethu kungazuza kakhulu uma abantu abaningi besuka ekudleni okusekelwe ezilwaneni baye ekudleni okusekelwe ezitshalweni okuhlanganisa nesoya.
Ngakho-ke ngokuzayo lapho uzwa izindaba eziwubuwula zokuthi isoyi iyigalelo elibi kangakanani empilweni yomuntu noma endaweni ezungezile, buza ukuthi buphi ubufakazi.
