Ku golosale, mumakafika pamtundu womwe mumakonda wa madzi a lalanje mukawona chilinganizo chatsopano pashelefu chokhala ndi chikwangwani chofiira. "Chatsopano ndikusintha!" likufuula. "Tsopano ndi echinacea!" Simukutsimikiza kuti echinacea ndi chiyani, koma bwenzi lanu lapamtima lilumbirira kuthekera kwake kwamatsenga ndi kuthana ndi chimfine. Osakayikira, mumayang'ana mtengo. OJ wokhala ndi mpanda wolimba amawononga pang'ono, koma mumasankha kuti monga inshuwaransi yazaumoyo imapita, ndiye mtengo wotsika mtengo kwambiri woti mulipire. Malingana ngati amakoma bwino ngati choyambirira, mwina simumaganiziranso.

Chowonadi ndi chakuti, muyenera. Zitsamba OJ ndi chitsanzo cha mbewu yomwe ikukula ya "zakudya zogwira ntchito" yodzaza mashelufu ogulitsa ndi kusokoneza ogula. Ngakhale palibe tanthauzo lalamulo kapena lovomerezeka, Bruce Silverglade, mkulu wa zamalamulo ku Center for Science in the Public Interest (CSPI), akuti mawu amalonda amatanthauzira zakudya zogwira ntchito ngati zodyedwa zilizonse zomwe zili ndi zosakaniza zilizonse zomwe zimaperekedwa kuti zithandizire thanzi kuposa zakudya zoyambira. . Izi zimaphatikizapo zakudya zomwe zitsamba kapena zowonjezera zidawonjezeredwa kuti zithandizire kupatsa thanzi kapena kupititsa patsogolo zotsatira zathanzi, monga lycopene mu tomato.

Onyenga azitsamba?

Izi sizokhudza kudya mphamvu kapena moyo wautali; zakudya zomwe zikukambidwazo zimati zimathandizira chitetezo chamthupi, zimathandizira kukumbukira komanso kukhazikika komanso kupewa kukhumudwa.

Mwamwayi, akatswiri ambiri amaganiza kuti opanga akuwonjezera pazinthu zazing'onozing'ono zomwe akuti ndizotsatira zake sizikhala ndi vuto lililonse. Ngakhale chakudyacho chitakhala ndi mlingo wokhazikika wamankhwala azitsamba, mankhwala azitsamba ambiri ayenera kumwedwa kwa milungu ingapo asanawonekere. Muzochitika izi, mudzangowononga ndalama zanu. Komabe, ndizotheka kumwa mopitirira muyeso pa mavitamini ndi mchere wina (kuphatikizapo chitsulo, vitamini A ndi chromium). Chifukwa chake ngati zakudya zanu zambiri zimakhala ndi zakudya zopatsa thanzi kwambiri, mutha kudziyika nokha pachiwopsezo.

Kukakamira kuletsa zonena zabodza

CSPI, bungwe lopititsa patsogolo phindu la ogula, likuyesetsa kuteteza ogula kuzinthu zokayikitsa komanso zonamizira.Bungweli lapereka madandaulo ambiri ku Food and Drug Administration ndikulimbikitsa kuti zosakaniza zogwira ntchito zitsimikizidwe kuti ndizabwino komanso kuti zonena kuti zivomerezedwe asanagulitsidwe. Afunsanso chigamulo chomwe chingalepheretse opanga kutsatsa zakudya zamagetsi monga zowonjezera zowonjezera kuti athawe malamulo a FDA pazakudya. "Malamulowa ali ndi ziganizo zambiri zomwe sizikumveka bwino kapena ayi," avomereza a Christine Lewis, Ph.D., director of the office of zakudya zopatsa thanzi, kulemba ndi zowonjezera zowonjezera za FDA. "Ndi ntchito yathu kutsutsa zonena za opanga," akuwonjezera. "Izi zingakhale zovuta kuchita."

Lewis akuumirira kuti a FDA "ali ndi chidwi kwambiri ndi nkhani zomwe CSPI yadzutsa ndipo idzapitirizabe kuyesetsa kuonetsetsa kuti zosakaniza ndi zotetezeka komanso zolemba ndi zoona komanso zolondola." Mpaka lamulo lovomerezeka litaperekedwa, kusamala kumalangizidwa.

Malonjezo olimbikitsidwa

Osakhulupirira zonse zomwe mwawerenga. Kuchokera ku Center for Science in the Public Interest, nayi mndandanda wazinthu zomwe sizingakhale zopitilira muyeso zomwe amati ndi izi:

Zolemba Zamtundu Tiyi wobiriwira wa ginseng-, kava-, echinacea- ndi guarana "amapangidwa kuti abwezeretse, kutsitsimutsa ndi kupititsa patsogolo moyo wabwino." Opanga adazilemba ngati zowonjezera kuti apewe malamulo okhwima ofunikira kuti agulitse chakudya. Awa ndi malo otuwa. Bruce Silverglade wa CSPI akuti, "Food and Drug Administration imayimitsa nthawi zina, koma osati nthawi zonse. Komanso, kukhazikitsa sikofunikira kwambiri ku FDA."

Brain Gum Chingamuchi chili ndi phosphatidyl serine, chinthu chonga mafuta chochokera ku soya. Chogulitsachi, chomwe chimati "chimawonjezera chidwi," chimagulitsidwa ngati chowonjezera kotero sichiyenera kutsatira malamulo a FDA olamulira zakudya.

MtimaBar Chizindikiro chotchingira chotchingira chotchedwa L-arginine chotchinga chotchinga chimati chitha kugwiritsidwa ntchito "pakuwongolera zakudya zamatenda." (Arginine ndi amino acid wofunikira kupanga nitric oxide, chotengera chotengera magazi.) Amadziwika kuti ndi chakudya chamankhwala chomwe chingagwiritsidwe ntchito moyang'aniridwa ndi adotolo kuti apewe malamulo amilandu a FDA asanagulitsidwe.

Heinz Ketchup Malonda amadzitamandira kuti lycopene mu ketchup "ingathandize kuchepetsa chiopsezo cha prostate ndi khansa ya pachibelekero." Kampaniyo imangopanga zotsatsa osati pamalebulo chifukwa Federal Trade Commission, yomwe imayang'anira kutsatsa, siyifuna kutsimikizira zonena zotere, pomwe zonena zotere pazakudya sizingaloledwe ndi a FDA. kusachita kafukufuku wokwanira.

Msuzi wa V8 wa Campbell Zolemba zimati ma antioxidants omwe akupangidwa "atha kutengapo gawo lofunikira pochepetsa kusintha komwe kumachitika ndikakalamba," zomwe zimanenedwa kutengera umboni woyambirira wa asayansi. Madzi amadzimadzi amakhalanso ndi sodium yambiri, yomwe imalimbikitsa kuthamanga kwa magazi mwa anthu omwe samva sodium, zomwe zimafala kwambiri ndi ukalamba.

Chenjerani ndi Wogula: Mavuto 7 ndi zakudya zogwira ntchito

1. Makampaniwa akadali osalamulidwa. "Opanga zakudya akuwonjezera zakudya ndi botanicals ku chakudya mosasamala," akutero Mary Ellen Camire, Ph.D., pulofesa wa sayansi ya chakudya ndi zakudya za anthu ku yunivesite ya Maine. Nthawi zambiri, samayang'ana ngati zosakaniza zingagwiritsidwe ntchito ndi thupi mwanjira imeneyo, kapena ngakhale zili zovulaza kapena zopindulitsa. (Chodziwika chokha ndichopanga madzi a lalanje okhala ndi calcium: Chifukwa calcium imalowa bwino ikamamwa vitamini C, izi zimapangitsa kukhala ndi thanzi labwino.)

2. Palibe Malipiro Omwe Amaperekedwa Tsiku ndi Tsiku. Bruce Silverglade wa CSPI anati: "Zitsamba zamankhwala zimatha kuthandizana ndi mankhwala wamba, koma sizikhala m'zakudya. Mukagula tchipisi ta chimanga ndi kava, mulibe njira yodziwira kuchuluka kwa zitsamba zomwe mukupeza. Kava ali ndi vuto lokonda kugona. Nanga mwana akadya thumba lonse? "

3. Ngati chikuwoneka ngati switi ... Kukhazikitsa zokhwasula-khwasula ndi zitsamba ndi zomwe akuti ndi michere ndi "njira yotsatsira kuti anthu azidya zakudya zopanda pake," akutero Camire.

4. Kusewera dokotala kumatha kukuyikani m'mavuto. Zina mwa zitsamba zomwe zikukambidwazo zidapangidwa kuti zizitha kuchiza matenda omwe ogula sangakwanitse komanso sayenera kuwunika payekha. "Saint Johnswort yawonetsedwa kukhala yothandiza pochiza kukhumudwa," akutero Silverglade. "Kodi ungadziwe bwanji ngati uli wokhumudwa kapena wovutika maganizo? Kodi uyenera kuti umadya msuzi wotonthozedwa kapena ukaonana ndi wazamisala?"

5. Kudya kwa mbatata kumatha kuwononga kwambiri kuposa m'chiuno mwako. Timaganiza kuti chilichonse mufiriji yathu ndioyenera kudya, koma sizili choncho ndi zakudya izi. Silverglade akulimbikitsanso kuti: “Ngati mukufuna kumwa mankhwala azitsamba, muwatenge ngati mankhwala owonjezera ndipo funsani dokotala za mmene angagwiritsire ntchito mankhwalawo. "Kudya chakudya ndi njira yolakwika yopezera mlingo woyenera wa mankhwala."

6. Zolakwitsa ziwiri sizipanga cholondola. "Simungagwiritse ntchito zakudya zotetezedwa kuti mulipirire zakudya zanu," akutero Camire.

7. Kamodzi sikokwanira. Akatswiri akuganiza kuti mitundu yambiri yazitsamba yomwe ili ndi zitsamba sizikhala ndi zokwanira zomwe zingagwire ntchito. Ngakhale atatero, zitsamba zamankhwala nthawi zambiri zimayenera kumwa kwa milungu ingapo phindu lisanayambike.
