Koma kodi olowa m'malo mwa shuga ali ndi thanzi labwino? Kodi pali chotsekemera chabwino kwambiri chopangira? Tinatembenukira ku zabwino zachipatala ndi zakudya kuti tipeze mndandanda wa zotsekemera zopangira komanso zowona, zowonongeka za sayansi za zotsekemera zopanga motsutsana ndi shuga.
Mbali Yosakhala Yabwino Kwambiri Yotsekemera Opanga vs.
Zikuwoneka ngati chikhumbo chozizwitsa chimakwaniritsidwa mu kaphukusi kakang'ono, kokongola. Muthabe kusangalala ndi khofi wanu wabwino komanso wokoma popanda zopatsa mphamvu. Koma kwa zaka zambiri, mikangano yomveka yakhala ikunena kuti zotsekemera zopangira zotsekemera zimatha kuyambitsa kunenepa.
"Opangira zotsekemera amalimbikitsa thupi lathu kuti lipange kulemera kwa mahomoni a insulin, omwe amachititsa kuti thupi lizisunga mafuta monga mafuta," akutero a Morrison. Ndipo ngakhale m'mawu am'mbuyomu a AHA adanenanso kuti zotsekemera zopanda thanzi zinali ndi mwayi wothandiza anthu kuti afikire ndi kusunga zolemera za zolinga zawo, adanenanso kuti umboniwo unali wochepa ndipo chifukwa chake ndi wosakwanira.

"Tikamamwa mankhwalawa, matupi athu amafunika kugwira ntchito molimbika kuti agwiritse ntchito, ndikusiya zinthu zochepa kuti ziwononge matupi athu kuzinthu zambiri zomwe timakumana nazo m'chilengedwe," akutero Jeffrey Morrison, MD, dotolo komanso mlangizi wazakudya. Makalabu olimbitsa thupi a Equinox.
Koma zikafika pazinthu zokoma, ndi ziti zomwe ndizolakwitsa kwambiri? Kodi ndi zotsekemera zabwino bwanji? Pamene mukuyezera ubwino ndi kuipa kwa zotsekemera zopangira zotsekemera motsutsana ndi shuga, werengani kuti mupeze kalozera wanu zabwino kwambiri ndi zoyipitsitsa pamndandanda wa zotsekemera zopangira izi.
Aspartame
Ogulitsidwa pansi pa mayina ngati NutraSweet® ndi Equal®, aspartame ndi imodzi mwazomwe zimayambitsa mikangano komanso zophunzira zotsekemera pamsika.Ndipotu, "pofika m'chaka cha 1994, 75 peresenti ya madandaulo onse osagwiritsa ntchito mankhwala osokoneza bongo ku FDA anali kuyankha aspartame," akutero Cynthia Pasquella-Garcia, katswiri wa zachipatala komanso dokotala wamankhwala. Ma gripes amenewo anali kuyambira kusanza komanso kupweteka mutu m'mimba komanso khansa.
Aspartame vs. Shuga: Aspartame imakhala ndi ma calories asanu ndipo imagwiritsidwa ntchito kuphika. Muli msuzi wa zinthu zosazolowereka, monga phenylalanine, aspartic acid, ndi methanol.

"Izi zitha kuyambitsa kagayidwe kachakudya acidosis, komwe kumakhala asidi wambiri m'thupi ndipo kumayambitsa matenda." Ngakhale kulumikizana kwa aspartame pamavuto azaumoyo kwaphunziridwa kwambiri, pali umboni wochepa kwambiri wosachotsa pamashelufu. Food and Drug Administration (FDA) yakhazikitsa chakudya chololedwa tsiku lililonse (ADI) pa 50 mg / kg ya kulemera kwa thupi, chomwe chimafanana ndi zitini 20 zakumwa zotsekemera za aspartame kwa mayi wa mapaundi 140.
Sucralose
Wodziwika kuti Splenda (komanso wogulitsidwa ngati Sukrana, SucraPlus, Candys, ndi Nevella), sucralose idapangidwa koyambirira m'ma 1970 ndi asayansi omwe amayesa kupanga mankhwala ophera tizilombo.

Mu 1998, a FDA adamaliza maphunziro opitilira 100 ndikupeza kuti chotsekemera sichikhala ndi vuto la khansa kapena chiopsezo chokhudzana ndi matendawa. Zaka khumi pambuyo pake, Duke University inamaliza maphunziro a masabata a 12-omwe amathandizidwa ndi makampani a shuga-amapereka Splenda kwa makoswe ndipo adapeza kuti amapondereza mabakiteriya abwino ndikuchepetsa chimbudzi chamatumbo m'matumbo. "Zofukufukuzo (pamene zinali zinyama) ndizofunikira chifukwa Splenda adachepetsa ma probiotics, omwe amathandiza kwambiri kuti kugaya chakudya kukhale koyenera," anatero Ashley Koff, RD, katswiri wa zakudya zovomerezeka komanso woyambitsa The Better Nutrition Program.

Ngakhale zili choncho, amayi apakati amalangizidwa kuti azigwiritsa ntchito saccharin mosamala.
Ponena za phindu lochepetsa thupi, saccharin ili ndi ma calories osapitilira muyeso wa magazi, koma akatswiri azakudya amakhulupirira kuti zotsekemera zimatha kulumikizidwa ndi kunenepa. "Nthawi zambiri munthu akadya chakudya chotsekemera, thupi limayembekezera kuti chakudyacho chiziyenda ndi chakudyacho, koma thupi likapanda kupeza ma calories amenewo, limawayang'ana kwina," akutero Glassman. "Choncho pa calorie iliyonse yomwe mukuganiza kuti mumasunga posankha chokometsera chochita kupanga, mutha kupeza mwa kudya zopatsa mphamvu zambiri pamapeto pake." ADI ya saccharin ndi 5 mg / kg ya thupi yomwe ili yofanana ndi mayi wa mapaundi 140 akudya mapaketi 9 mpaka 12 a zotsekemera.

Stevia
Mafani a therere la ku South America amawakonda kuposa shuga wamba wapa tebulo chifukwa chopanda calorie. Imapezeka mumitundu yonse ya ufa ndi madzi ndipo akatswiri azakudya amazindikira kuti ilibe mankhwala komanso yopanda poizoni. (Zowonjezera zambiri: Ayi, nthochi ilibe shuga wambiri kuposa donut.)
Stevia motsutsana ndi Shuga: Mu 2008, a FDA adalengeza kuti stevia "nthawi zambiri imawonedwa ngati yotetezeka," zomwe zikutanthauza kuti itha kugwiritsidwa ntchito ngati choloweza m'malo mwa shuga. Kafukufuku wasonyeza kuti stevia imatha kutsitsa insulin, ndikupangitsa kuti ikhale njira yabwino kwa odwala matenda ashuga, ngakhale ena akadali ndi nkhawa ndi zopangira zotsekemera zomwe zimagwiritsa ntchito stevia. "Ngakhale stevia amadziwika kuti ndiwotetezeka, sitikudziwa zamitundu yonse yomwe imagulitsidwa m'misika yayikulu," akutero Koff. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) yapereka ADI ya 4 mg/kg (kapena 12 mg/kg kulemera kwa thupi kwa steviol glycoside) kutanthauza kuti munthu wolemera mapaundi 150 akhoza kudya pafupifupi mapaketi 30.
Xylitol
Ndi kukoma kwapafupi kofananira ndi shuga, mowa wodziwika bwino wa shuga wochokera ku khungwa la birch umapezeka mu zipatso zambiri ndi ndiwo zamasamba ndipo amapangidwa m'thupi. Xylitol imakhala ndi zopatsa mphamvu pafupifupi 2.4 gramu pa gramu iliyonse, imakhala ndi 100% ya kukoma kwa shuga patebulo, ndipo ikawonjezeredwa kuzakudya zitha kuwathandiza kukhalabe onyowa komanso owoneka bwino. (Pali zambiri za mowa wa shuga komanso ngati ali ndi thanzi kapena ayi.)
Xylitol motsutsana ndi Shuga: Othandizira njira iyi yoyendetsedwa ndi FDA amakonda zotsekemera zopanda mafuta chifukwa ndizabwino kwa odwala matenda ashuga ndipo kafukufuku wasonyeza kuti imalimbikitsa thanzi la mano.
