Q: Ngaphandle kweeoyile ze-hydrogenated kunye nesiraphu yengqolowa ene-high-fructose, sesiphi isithako endifanele ukusiphepha?

A: Amafutha okuhambisa amashishini afunyenwe kwioyile ye-hydrogenated kunye noshukela ongezelelweyo- hayi nje isiraphu yengqolowa ephezulu-ngokuqinisekileyo zizithako ezibini eziphezulu ekufuneka uzinciphisile kwaye uziphephe. Bobabini ngokwenene bakwiklasi yabo, kodwa yintoni ofanele uyiphephe ukusondeza abo bathathu baphezulu? I-Bisphenol-a, eyaziwa ngokuba yi-BPA.

Ndiqale ndafunda malunga neziphumo ezibi zezempilo ze-BPA malunga neminyaka esibhozo eyadlulayo kudliwanondlebe endilwenzile noJohn Williams, Ph.D. Uxelele amabali malunga neempembelelo ezigqithisileyo ze-estrogenic kwizilwanyana ezisingqongileyo eziye zavezwa ukuchithwa kwenkunkuma kunye nokulahla okubandakanya inani elikhulu le-BPA. Ikhonkco elilahlekileyo kum ngelo xesha yayiludibaniso lomntu kunye nefuthe le-BPA ebantwini.

Nangona kunjalo, kulo nyaka uphelileyo kukho phantse i-60 yophando epapashiweyo ejonge iziphumo ze-BPA kwimpilo yabantu. Ezi zinto zifunyanisiweyo kunye nokunye kwakushwankathelwe kuphononongo lwamva nje olupapashwe kwiphephancwadi I-Toxicology yokuzala. Ababhali bafumanise ukuba ukubonakaliswa kwe-BPA kunxulunyaniswa nomngcipheko owandayo:

• ukuphuma kwesisu

• Ukunikezelwa kwangaphambi kwexesha

• ukunciphisa umsebenzi wesini oyindoda

• i-polycystic ovary syndrome (PCOS)

• kuguqulwe ukugxila kwehomoni yedlala lengqula

• ukungasebenzi komzimba

• uhlobo-2 lweswekile

• isifo sentliziyo

• ukuguqula ukusebenza kwesibindi

• ukutyeba

• Uxinzelelo lwe-oxidative kunye ne-fl ammation

Kutheni i-BPA imbi?

I-BPA yi-endocrine-ephazamisa i-hormone-ubukhulu becala yimichiza esebenza ukuphazamisa ukusebenza komzimba wehomoni yethu. Yenza umonakalo ngeendlela ezahlukeneyo ekusebenzeni njenge-estrogen, ukuvimba isenzo se-estrogen, ukubopha kwii-receptors ze-thyroid kwaye ngaloo ndlela kuphazamise umsebenzi we-thyroid, kunye nokunye.

Andiboni nakuphi na okunye ukutya okanye isithako ekuboneleleni ngokutya kwethu kwezi ntlobo zeziphumo. Ngethamsanqa ngenxa yesikhalo sabathengi, i-BPA iye yasuswa kwiiplastikhi ezithengiselwe ukusetyenziswa njengeebhotile zamanzi kunye nezitya zokutya. Kwiminyaka nje emihlanu edlulileyo xa mna nenkosikazi yam sasinabantwana bethu bokuqala (sasinamawele), ukufumana iibhotile ezingenasimahla ze-BPA kwakunzima kakhulu kwaye kubiza kakhulu; ukususela ngoJulayi 2012, nangona kunjalo, i-FDA iye yavala ukusetyenziswa kwayo kwiibhotile zeentsana kunye neekomityi ze-sippy.

Ukuba i-BPA evela kwizikhongozeli zokutya kunye namanzi ayiseyiyo ingxaki, uvela phi kwi-BPA? Ngelishwa iitoni ezizigidi ezintandathu ze-BPA ziveliswa unyaka nonyaka, yiyo yonke indawo. Isetyenziswa njengombathiso kwiirisithi, nangona ngaphandle kokuba uyivenkile esemthethweni yokutshintshela i-BPA kwiirisithi kusenokwenzeka ukuba incinci. I-BPA ikwafumaneka eluthulini olujikeleze indlu yakho-ewe, uthuli; yindlela ekuxhaphake ngayo le toxin kwimeko-bume yethu. Ngenxa yoko, ukubhencwa ngokutya mhlawumbi ayingowona mthombo mkhulu. Kodwa usenokunciphisa ukuvezwa kunye nokuqokelela kwe-BPA. Nazi izinto ezimbini ekufuneka ujonge kuzo.

1. Yiba nobulumko malunga neenkonkxa. I-BPA kukugquma ngaphakathi kweetoti. Ukuphepha imifuno enkonkxiweyo kunye nokukhetha okutsha okanye okunqabileyo akufuneki kube nzima kakhulu kutshintsho. Ukuthenga iimbotyi ezomisiweyo endaweni yeembotyi ezisemathinini akuyi kunciphisa ukubonakala kwakho kwi-BPA, kodwa kuyabiza kakhulu kwaye kwenza ukuba kube lula ukulawula ukutya kwakho kwe-sodium. Xa uthenga iimveliso zetumato, jonga ezo zithengiswa kwiijagi zeglasi xa kunokwenzeka. Ngelixa kukho iinkonkxa ezingenanto ye-BPA yeembotyi, azixhaphakanga kakhulu kwiimveliso zetumato, njengoko iasidi yeetumato yenza ukuba ukhuseleko lwe-BPA lube yinto ebalulekileyo ukukhusela kwisinyithi seenkonkxa.

2. Ukunciphisa umzimba. I-BPA yikhemikhali enyibilikayo enamafutha enokuqokelelwa kwiiseli zakho ezityebileyo. Ke ngelixa usenza konke okusemandleni akho ukugcina indlu yakho i-BPA-ingenathuli ngelixa ungagcini ukutya kwakho kwiiplastikhi ezinayo i-BPA, iindaba ezimbi kukuba wena inokuba yeyona nqanawa yokugcina iBPA ebomini bakho. Iindaba ezimnandi zezokuba umzimba wakho unokukhupha ngokukhawuleza i-BPA ngomchamo. Nje ukuba uyikhulule kwiiseli zakho zamafutha, umzimba wakho unokuwususa. Ukulahlekelwa ubunzima kunye nokuhlala ubhityile kunokuba yenye yeendlela ezilungileyo zokunciphisa ukubonakaliswa kwakho okungapheliyo kunye nokuqokelela kwe-BPA.

Ngethamsanqa iingozi zempilo ezinxulunyaniswa ne-BPA ziqala ukufikelela kubantu abanamandla okulawula ubukho bayo yonke loo khemikhali. I-FDA isanda kubhala i-BPA ngokuthi "ikhemikhali yenkxalabo," ngoko ke ngethemba lokuba kuya kubakho uphando oluninzi kunye nommiselo ojikeleze i-BPA kungekudala. Okwangoku, nxiba ukutya kwakho okunkonkxiweyo kwaye uhlale ubhityile.
