Umbuzo: Ngaphandle kukawoyela we-hydrogenated nesiraphu ye-high-fructose yommbila, yisiphi isithako esisodwa okufanele ngisigweme?

A: Amafutha we-Industrial trans atholakala kumafutha we-hydrogenated kanye noshukela ongeziwe-hhayi nje isiraphu ye-high-fructose yommbila-ngokuqinisekile izithako ezimbili eziphezulu okufanele uzinciphise futhi uzigweme. Bobabili basekilasini labo, kodwa yini okufanele uyigweme ukuze ukhiphe abathathu abaphezulu? I-Bisphenol-a, eyaziwa nangokuthi i-BPA.

Ngiqale ngafunda ngemiphumela emibi yezempilo yeBPA cishe eminyakeni eyisishiyagalombili eyedlule engxoxweni ebengiyenza noJohn Williams, Ph.D. Uxoxe izindaba ngemiphumela eyeqisayo ye-estrogenic ezilwaneni izindawo zazo ezivezwe ukuchithwa kwemfucuza nokulahlwa okubandakanya inani elikhulu le-BPA. Isixhumanisi esilahlekile kimi ngaleso sikhathi kwakuwukuxhumana komuntu kanye nemiphumela ye-BPA kubantu.

Kodwa-ke, ngonyaka odlule kube nezifundo zocwaningo ezicishe zibe ngama-60 ezishicilelwe kubhekwa imiphumela yeBPA empilweni yomuntu. Lokhu okutholakele nokunye kufingqiwe ekubuyekezweni kwakamuva okushicilelwe kumagazini I-Toxicology Yokuzala. Ababhali bathole ukuthi ukuchayeka kwe-BPA kuhlotshaniswe nengozi eyengeziwe yoku:

• ukuphuphuma kwesisu

• ukulethwa ngaphambi kwesikhathi

• kunciphise ukusebenza kowesilisa ngokocansi

• i-polycystic ovary syndrome (i-PCOS)

• kushintshe ukugxila kwehomoni yegilo

• ukungasebenzi kahle kwamasosha omzimba

• uhlobo-2 sikashukela

• isifo senhliziyo nemithambo yegazi

• kushintshe ukusebenza kwesibindi

• ukukhuluphala ngokweqile

• ingcindezi ye-oxidative kanye ne-fl ammation

Kungani I-BPA Yimbi?

I-BPA iyi-endocrine-ephazamisa i-hormone-empeleni iyikhemikhali elenza ukuphazamisa ukusebenza komzimba ovamile kwamahomoni. Idala umonakalo ngezindlela ezahlukahlukene ekusebenzeni njenge-estrogen, ivimbe isenzo se-estrogen, ibophezele kuma-receptors egilo futhi ngaleyo ndlela iphazamise ukusebenza kwegilo, nokunye.

Angiboni okunye ukudla noma isithako ekunikezelweni kwethu kokudla okuba nalezi zinhlobo zemiphumela. Ngenhlanhla ngenxa yokukhala kwabathengi, i-BPA isuswe ngokuphelele opulasitiki abathengiselwa ukusetshenziswa njengamabhodlela amanzi neziqukathi zokudla. Eminyakeni emihlanu nje edlule lapho mina nomkami sinezingane zethu zokuqala (sasinamawele), ukuthola amabhodlela angenayo i-BPA kwakunzima kakhulu futhi kubiza; kusukela ngoJulayi 2012, noma kunjalo, i-FDA ivimbele ukusetshenziswa kwayo emabhodleleni ezingane nasezinkomishini ezinamaqhuqhuva.

Uma i-BPA evela ezitsheni zokudla namanzi kungasadingeki, uthola kuphi i-BPA? Ngeshwa amathani ayizigidi eziyisithupha e-BPA akhiqizwa minyaka yonke, ngakho atholakala yonke indawo. Isetshenziswa njengesembozo kumarisidi, nakuba ngaphandle kokuthi uyisitolo esisemthethweni ukudluliselwa kwe-BPA eguquguqukayo kusuka kumarisidi cishe kuncane kakhulu. I-BPA iphinde itholakale othulini oluzungeze indlu yakho-yebo, uthuli; injalo yonke indawo lobu buthi endaweni yethu. Ngenxa yalokhu, ukuvezwa ngokudla mhlawumbe akuwona umthombo omkhulu kunayo yonke. Kodwa usengakwazi ukunciphisa ukuchayeka kanye nokunqwabelana kwe-BPA. Nazi izinto ezimbili okumele ugxile kuzo.

1. Hlakanipha ngamakani. I-BPA ukugqoka ingaphakathi lamathini. Ukugwema imifino ekheniwe nokukhetha okusha noma okufriziwe akufanele kube nzima kakhulu ekushintsheni. Ukuthenga ubhontshisi omisiwe esikhundleni sikabhontshisi okusemathinini ngeke kunciphise ukuvezwa kwakho kwi-BPA kuphela, kepha kubiza kakhulu futhi kwenza kube lula ukulawula ukungena kwakho kwe-sodium. Lapho uthenga imikhiqizo katamatisi, funa leyo ethengiswa ezitsheni zengilazi lapho kungenzeka khona. Nakuba kukhona amathini kabhontshisi angenayo i-BPA, awavamile kakhulu emikhiqizweni katamatisi, njengoba i-asidi katamatisi yenza ukuvikela kwe-BPA kube ingxenye ebalulekile yokuvikela ensimbi yamathini.

2. Ukwehlisa isisindo. I-BPA ikhemikhali elincibilika emafutheni elinganqwabelana kumaseli akho amafutha. Ngakho-ke ngenkathi wenza konke okusemandleni ukugcina indlu yakho i-BPA ingenalo uthuli kuyilapho ungagcini ukudla kwakho kumapulasitiki okungenzeka aqukethe i-BPA, izindaba ezimbi ukuthi wena kungaba isitsha esikhulu sokugcina se-BPA empilweni yakho. Izindaba ezimnandi ukuthi umzimba wakho ungakhipha kalula i-BPA ngomchamo. Uma usuyikhulula kumaseli akho anonile, umzimba wakho ungayisusa. Ukwehla kwesisindo nokuhlala unciphile kungaba enye yezindlela ezingcono kakhulu zokunciphisa ukuvezwa kwakho okungapheli nokuqongelelwa kwe-BPA.

Ngenhlanhla izingozi zezempilo ezihambisana ne-BPA seziqala ukufinyelela kubantu abanamandla okulawula ukuba khona kwamakhemikhali anjalo yonke indawo. I-FDA isanda kubiza i-BPA ngokuthi "ikhemikhali elikhathazayo," ngakho-ke ngethemba lokuthi kuzoba nocwaningo olwengeziwe kanye nomthethonqubo ozungeze i-BPA kungekudala. Okwamanje, gqoka ukudla kwakho okusemathinini futhi uhlale unciphile.
