Q: Kupatula mafuta a hydrogenated ndi manyuchi a chimanga cha-fructose, ndichinthu chiti chimodzi chomwe ndiyenera kupewa?

Yankho: Mafuta opangidwa ndi mafakitale omwe amapezeka m'mafuta a hydrogenated ndi shuga wowonjezera-osati madzi a chimanga a fructose-ndizosakaniza ziwiri zomwe muyenera kuzichepetsa ndikuzipewa. Onse ali mgulu laokha, koma muyenera kupewa chiyani kuti mutenge atatu apamwamba? Bisphenol-a, yomwe imadziwikanso kuti BPA.

Ndinaphunzira koyamba za zovuta za BPA pafupifupi zaka zisanu ndi zitatu zapitazo poyankhulana komwe ndidachita ndi John Williams, Ph.D. Iye adanena nkhani zokhudzana ndi zotsatira za estrogenic kwambiri pa zinyama zomwe malo awo adakhudzidwa ndi kutaya zinyalala ndi kutaya zomwe zimaphatikizapo kuchuluka kwa BPA. Ulalo wosowa kwa ine panthawiyo unali kulumikizana kwa anthu komanso zotsatira za BPA pa anthu.

Komabe, mchaka chatha pakhala kafukufuku pafupifupi 60 wofalitsidwa poyang'ana zomwe BPA imakhudza thanzi la munthu. Zotsatirazi ndi zina zinafotokozedwa mwachidule mu ndemanga yaposachedwa yomwe idasindikizidwa m'magaziniyi Toxicology Yobereka. Olembawo apeza kuti kuwonekera kwa BPA kumalumikizidwa ndi chiopsezo chowonjezeka cha:

• kupita padera

• kubereka msanga

• amachepetsa kugonana kwamwamuna

• polycystic ovary syndrome (PCOS)

• yasintha kuchuluka kwa mahomoni a chithokomiro

• Blunted chitetezo ntchito

• mtundu wa 2 shuga

• matenda a mtima

• kusintha chiwindi ntchito

• kunenepa kwambiri

• kupsyinjika kwa oxidative komanso mu fl ammation

Chifukwa Chiyani BPA Ndi Yoipa?

BPA ndi mahomoni osokoneza bongo a endocrine-makamaka ndi mankhwala omwe amasokoneza thupi lathu. Zimasokoneza m'njira zosiyanasiyana kuchokera pakuchita ngati estrogen, kutsekereza kuchitapo kanthu kwa estrogen, kumangiriza olandila chithokomiro motero kuwononga chithokomiro, ndi zina zambiri.

Sindikuwona chakudya china chilichonse kapena chosakaniza mu chakudya chathu chokhala ndi zotsatirazi. Mwamwayi chifukwa cha kulira kwa ogula, BPA yathetsedwa m'mapulasitiki ogulitsidwa kuti agwiritsidwe ntchito ngati mabotolo amadzi ndi zotengera zakudya. Zaka zisanu zokha zapitazo pamene ine ndi mkazi wanga tinali ndi ana athu oyamba (tinali ndi mapasa), kupeza mabotolo opanda BPA kunali kovuta kwambiri komanso okwera mtengo; kuyambira Julayi 2012, komabe, a FDA adaletsa kugwiritsa ntchito kwake m'mabotolo a ana ndi makapu a sippy.

Ngati BPA yochokera mumakontena azakudya ndi madzi salinso vuto, kodi mukudziwa kuti BPA? Tsoka ilo matani sikisi miliyoni a BPA amapangidwa chaka chilichonse, chifukwa chake amapezeka paliponse. Amagwiritsidwa ntchito ngati zokutira pama risiti, ngakhale ngati muli shopaholic yovomerezeka, kutumiza kwa BPA kuchokera kumalisiti kumakhala kochepa. BPA imapezekanso mufumbi mozungulira nyumba yanu-inde, fumbi; ndi momwe ubweya wambiriwu ulili ponseponse m'dera lathu. Zotsatira zake, kuwonetseredwa kudzera pachakudya mwina sichomwe chimayambitsa kwambiri. Koma mutha kuchepetsa kuchepa kwa BPA. Nazi zinthu ziwiri zofunika kuziganizira.

1. Khalani anzeru pazitini. BPA ndikuphimba mkati mwa zitini. Kupewa zamasamba zamzitini ndikusankha mwatsopano kapena mazira sikuyenera kukhala kovuta kwambiri. Kugula nyemba zouma m'malo mwa nyemba zamzitini sikungochepetsa kuchepa kwanu kwa BPA, koma kumakhala kopindulitsa ndipo kumapangitsa kuti kusungunuka kwanu kusakhale kosavuta. Pogula zinthu za phwetekere, yang'anani zomwe zimagulitsidwa m'mitsuko yamagalasi ngati kuli kotheka. Ngakhale pali zitini zopanda BPA za nyemba, ndizochepa kwambiri pazogulitsa phwetekere, chifukwa acidity ya tomato imapangitsa kutchinjiriza kwa BPA kukhala chinthu chofunikira kwambiri poteteza chitsulo cha zitini.

2. Kuchepetsa thupi. BPA ndi mankhwala osungunuka amafuta omwe amatha kudziunjikira m'maselo anu amafuta. Chifukwa chake ngakhale mukuyesetsa kuti nyumba yanu BPA ikhale yopanda fumbi osasunga zakudya zanu m'mapulasitiki omwe ali ndi BPA, nkhani zoyipa ndizakuti inu ikhoza kukhala chotengera chachikulu chosungira BPA m'moyo wanu. Nkhani yabwino ndiyakuti thupi lanu limatha kutulutsa BPA mosavuta kudzera mkodzo. Mukamasula ku maselo anu amafuta, thupi lanu limatha kuwachotsa. Kutaya thupi komanso kukhala wopanda mafuta ikhoza kukhala imodzi mwanjira zabwino kwambiri zochepetsera kuwonekera kwanu kwakanthawi ndi kuchuluka kwa BPA.

Mwamwayi zowopsa zathanzi zomwe zimakhudzana ndi BPA zikuyamba kufikira anthu omwe ali ndi mphamvu zowongolera kupezeka kwa mankhwala ngati amenewa. A FDA adatcha BPA posachedwa kuti ndi "mankhwala okhudzika," tikukhulupirira kuti padzakhalanso kafukufuku ndi malamulo ozungulira BPA posachedwa. Pakadali pano, valani zakudya zanu zamzitini ndikukhala owonda.
