Kuchitoro, iwe unosvika kune yako yaunofarira brand yejusi reorenji kana iwe ukaona fomula nyowani pasherefu yakanyorwa nebhenji rakatsvuka. "Nyowani nekuvandudzwa!" inodanidzira. "Zvino nechichacea!" Iwe hauna chokwadi chaizvo kuti echinacea chii, asi shamwari yako yepamoyo inopika neayo mashiripiti echando uye kugona kurwisa furu. Zvimwe unokahadzika, unotarisa mutengo. Iyo OJ yakasimbiswa inodhura zvishoma, asi iwe unofunga kuti seinishuwarenzi yehutano inoenda, ndiwo mutengo wakachipa wekubhadhara. Chero bedzi ichinaka sepakutanga, iwe haungazvipi pfungwa yechipiri.

Chokwadi ndechokuti, unofanira. Iyo herbal OJ muenzaniso wechirimwa chirikura che "chikafu chinoshanda" chakatsvikinyidzana mumasherufu ezvitoro uye zvinovhiringa vatengi. Kunyangwe pasina tsananguro yepamutemo kana yepamutemo, Bruce Silverglade, mutungamiriri wezvemitemo weCentre for Science muPublic Interest (CSPI), anoti izwi rekutengesa rinotsanangura chikafu chinoshanda sechinhu chero chipi zvacho chinodyiwa chine chero zvigadzirwa zvinoitirwa kupa hutano kunze kwekudya kwekutanga. . Izvi zvinosanganisira chikafu kune ayo mahebhu kana zvinowedzerwa zvakawedzerwa kunofungidzirwa kunatsiridza kukosha kwehutano kana kusimudzira mhedzisiro yehutano hwezvinhu zvinowanzoitika, senge iyo lycopene mumadomasi.

Vanyengeri vemakwenzi?

Izvi hazvisi zvekudyira simba kana kuti hupenyu hurefu; Zvikafu zviri kutaurwa zvinoti zvinosimudzira immune system kushanda, kunatsiridza ndangariro uye kuisa pfungwa uye kunyange kubvisa kushushikana.

Neraki, nyanzvi zhinji dzinofunga kuti vagadziri vari kuwedzera huwandu hwakadai husina basa hwezvinhu zvinonzi zvine hutano mumubvunzo zvekuti mhedzisiro ndeyekuti ivo havazove nemhedzisiro zvachose. Kunyange kana chigadzirwa chekudya chiine mushonga wemishonga wakanyatsogadziriswa, mishonga yakawanda yemishonga inofanira kutorwa kwemavhiki akati wandei isati yaonekwa. Muzviitiko izvi, iwe unenge uchingotambisa mari yako. Zvakadaro, zvinokwanisika kuwedzeredza pane mamwe mavitamini uye mamineral (kusanganisira ayoni, vhitamini A uye chromium). Saka kana ruzhinji rwekudya kwako rwukaumbwa nezvikafu zvakapfumiswa, unogona kunge uri kuzviisa panjodzi.

Kusundira kurambidzwa pamanyepo ekunyepa

Iyo CSPI, isingaite purofiti yevatengi yekukurudzira sangano, iri kushanda kudzivirira vatengi kubva kune zvinokakavara zvigadzirwa uye zvinotsausa zvirevo.Sangano rakamhan'ara zvichemo zvakawanda kuFood and Drug Administration ichikurudzira kuti zvinhu zvinoshanda zviratidzike kuti zvakachengeteka uye kuti zvikwangwani zvinotenderwa kusati kwashambadzwa. Vakakumbirawo mutongo waizodzivirira vagadziri kubva pakushambadzira chikafu chinoshanda sezvekudya kuti vatize mirau yeFDA yezvigadzirwa zvekudya. "Mitemo yakazara nemashoko asina kunyatsotsanangurwa kana kunzwisiswa," anobvuma kudaro Christine Lewis, Ph.D., mutungamiriri wehofisi yezvigadzirwa zvinovaka muviri, kunyora uye kudya kweFDA. "Ibasa redu kupokana nezvakataurwa nevagadziri," anowedzera. "Izvozvo zvinogona kuoma kuita."

Lewis anosimbirira kuti FDA "inofarira zvikuru nyaya dzakasimudzwa neCSPI uye ichave ichiwedzera nhamburiko dzekuona kuti zvigadzirwa zvakachengeteka uye mavara ndeechokwadi uye akarurama." Kusvikira mvumo yepamutemo yapihwa, kungwarira kunorayirwa.

Pumped-up zvipikirwa

Usatenda zvose zvaunoverenga. Kubva kuCentre yeSainzi mune Ruzhinji Kufarira, heino runyorwa rwezvigadzirwa zvingangodaro zvisiri izvo zvinopfuura zvavanoti ndeve:

Vadivelu Comedy Tribal Tonics Iyi ginseng-, kava-, echinacea- uye guarana-yakamisikidza matai egirini "akagadzirirwa kudzoreredza, kumutsiridza nekusimudzira hupenyu." Vagadziri vakavanyora sezviwedzero kuti vadzivise mirau yakaoma inodiwa kushambadzira chigadzirwa chikafu. Iyi inzvimbo yegrey. Bruce Silverglade weCSPI anoti, "Chikafu neDrug Administration inomisa dzimwe nguva, asi kwete nguva dzose. Uyezve, kumanikidzira hakusi chinhu chinonyanya kukosha kune FDA."

Brain Gum Ichi chingamu chine phosphatidyl serine, chinhu chakaita semafuta chakatorwa musoyabhinzi. Chigadzirwa, icho chinoti "chichivandudza kusangana," chinotengeswa sekuwedzera saka hazvifanirwe kutevedzera mitemo yeDAA inodzora chikafu.

HeartBar Chinyorwa cheL-arginine-chakasimbiswa chikafu chinodyiwa chinoti chinogona kushandiswa "pakurapa kwekudya kwevascular chirwere." (Arginine iamino acid inodikanwa kuburitsa nitric oxide, rinosvitsa muropa.) Inonyorwa sechikafu chekurapa chinoshandiswa pasi pekutarisirwa nachiremba kutsausa FDA pre-musika yehutano-yekuda mitemo.

Heinz Ketchup Ads vanozvirumbidza kuti lycopene mu ketchup "inogona kubatsira kudzikisa njodzi yeprostate uye kenza yemuromo wechibereko."

Muto wacho zvakare wakakwira nesodiyamu, inokurudzira kukwirisa kweropa mune vanhu vane svomhu, mamiriro anowedzera kuwanda nekukwegura.

Mutengi chenjera: 7 matambudziko ane zvinoshanda chikafu

1. Iyo indasitiri haisati yadzorwa. "Vagadziri vezvokudya vari kuwedzera zvinovaka muviri uye botanicals kune zvokudya willy-nilly," anodaro Mary Ellen Camire, Ph.D., purofesa wesayenzi yezvokudya uye kudya kwevanhu paYunivhesiti yeMaine. Muzviitiko zvakawanda, ivo havasi kutarisa kuti zvinongedzo zvinogona kushandiswa nemuviri mune iyo fomu, kana kunyangwe zvichikuvadza kana kubatsira. (Imwe inosarudzika ndeye vanogadzira calcium-yakasimba muto weorenji: Nekuti calcium inotorwa zvirinani kana yakatorwa nevhitamini C, izvi zvinoita kuti hutano huve hwakakwana.)

2.Hakuchina Zvinokurudzirwa Zuva Nezvekubvumidzwa. "Mishonga yemakwenzi inogona kutsigira mishonga yakajairwa," anodaro CSPI's Bruce Silverglade, "asi hazvisi zvekudya. Kana iwe ukatenga machipisi echibage nekava, hauna nzira yekuziva kuti yakawanda sei miriwo yauri kuwana. "Kava ane mushonga wekunyaradza. Ko kana mwana akadya bhegi rese?"

3. Kana ichitaridzika kunge bhawa rinotapira ... Kurongedza tudyira nemishonga uye zvinonzi zvinovaka muviri "igimmick yekushambadzira kuti vanhu vadye chikafu chisina kunaka," Camire anodaro.

4. Kutamba chiremba kunogona kukupinza mumatambudziko. Mimwe yemakwenzi ari mubvunzo akagadzirirwa kurapa mamiriro ehutano ayo mutengi asingakwanise uye haafanire kuzviongorora ega. "Saint Johnswort yakaratidzirwa kuve inobatsira pakurapa kushushikana," anodaro Silverglade. "Unoziva sei kana iwe uchingori pasi kana kuchipatara wakashushikana? Unofanirwa kunge uchidya muto wakasimbiswa here kana kuona chiremba wepfungwa?"

5. Chingwa chembatatisi chinogona kukuvadza zvakanyanya kupfuura chiuno chako. Isu tinofungidzira kuti chero chinhu chiri mufiriji yedu chakachengeteka kudya, asi handizvo zvazviri nezvikafu izvi. "Kana uchizotora mishonga yemishonga, itore mufomu yekuwedzera uye bvunza chiremba wako maererano nekugona kusangana kwezvinodhaka," Silverglade anokurudzira. "Kudya chikafu inzira yakashata yekuwana muyero wakakodzera wemushonga."

6. Zvakaipa zviviri hazviiti gwara. "Haugone kushandisa chikafu chakaomeswa kubhadhara mari yekudya," anodaro Camire.

7. Kamwe hakukwani. Vanamazvikokota vanofungidzira kuti mafomula akawanda ane mishonga yemakwenzi haana zvakakwana zvezvinhu zvinoshanda kuti zvive nemhedzisiro. Kunyangwe kana vakadaro, mishonga yemakwenzi kazhinji inofanirwa kutorwa kwemavhiki akati wandei mabhenefiti asati atanga.
