• Uphengululo lwe

Kwivenkile yegrosari, ufikelela kwibrand oyithandayo yejusi yeorenji xa ubona ifomula entsha kwishelufu eqatywe ngebhena ebomvu eqaqambileyo. "Entsha kwaye iphuculwe!" Iyakhwaza. "Ngoku nge-echinacea!" Awuqinisekanga ncam ukuba yintoni i-echinacea, kodwa umhlobo wakho osenyongweni ufunga ngobuchule bayo bokulwa nokubanda kunye nokulwa nomkhuhlane. Uthandabuza kancinci, ujonga ixabiso. I-OJ enqatyisiweyo ixabisa ngaphezulu kancinci, kodwa uthatha isigqibo sokuba njengoko i-inshurensi yezempilo ihamba, lixabiso eliphantsi kakhulu elinokuhlawula. Logama nje inencasa njengasekuqaleni, ngekhe uyinike ingcinga yesibini.

Inyaniso kukuba, kufanele. Ukuba i-herbal OJ ngumzekelo wesityalo esikhulayo "sokutya okusebenzayo" ukugcwala kwishelufa yokutya kunye nokudida abathengi. Nangona kungekho nkcazo yomthetho okanye esemthethweni, uBruce Silverglade, umlawuli wemicimbi yezomthetho yeZiko leSayensi kwiNdla yoLuntu (CSPI), uthi ixesha lokurhweba lichaza ukutya okusebenzayo njengazo naziphi na izinto ezidliwayo eziqulethe naziphi na izithako ezijoliswe ekuboneleleni izibonelelo zempilo ngaphaya kwesondlo esisisiseko. . Oku kubandakanya ukutya apho imifuno okanye izongezo zongezwe kwizityholo zokunyusa ixabiso lesondlo okanye ukukhuthaza iziphumo zezempilo zezinto ezenzeka ngokwendalo, ezinjenge-lycopene kwitumato.

Ngabakhohlisi bezityalo?

Le nto ayithethi ngokutya ukufumana amandla okanye ubomi obude; ukutya ekuthethwa ngawo kukonyusa ukusebenza kwamajoni omzimba, ukuphucula inkumbulo kunye noxinzelelo kunye nokuthintela uxinzelelo.

Ngethamsanqa, uninzi lweengcali zivakalelwa kukuba abavelisi bongeza ezi zixa zingenakuthelekiswa nanto kwizithako ezisempilweni ekuthiwa zizezempilo ekubhekiswa kuzo ukuba isiphumo esinokubakho kukuba azisayi kuba nasiphumo konke konke. Nokuba imveliso yokutya iqulethe idosi yemifuno elawulwa ngokuchanekileyo, amayeza amaninzi amayeza kufuneka athathwe iiveki ezininzi phambi kokuba kubonakale nasiphi na isiphumo. Kule meko, uya kuba uyichithile nje imali yakho. Sekunjalo, kunokwenzeka ukugqithisa kwiivithamini ezithile kunye neeminerali (kuquka isinyithi, i-vitamin A kunye ne-chromium). Ke ukuba uninzi lokutya kwakho lwenziwe kukutya okutyetyiswe kakhulu, unokuba uzibeka emngciphekweni.

Ukunyanzelwa kokuvalwa kwamabango obuxoki

I-CSPI, intlangano engenzi nzuzo yabathengi, isebenzela ukukhusela abathengi kwizithako ezithandabuzekayo kunye namabango alahlekisayo.Umbutho uye wafaka izikhalazo ezininzi kunye noLawulo lokuTya kunye neDrugs ekhuthaza ukuba izithako ezisebenzayo zibonakaliswe zikhuselekile kwaye amabango eleyibhile avunyiwe ngaphambi kokuthengisa. Baye bacela isigwebo esiya kuthintela abavelisi ekuthengiseni ukutya okusebenzayo njengezongezo zokutya ukubaleka imithetho ye-FDA yeemveliso zokutya. "Imithetho igcwele amabinzana angachazwanga kakuhle okanye angaqondakaliyo," uvuma uChristine Lewis, Ph.D., umlawuli weofisi yeemveliso zesondlo, iilebheli kunye nezongezo zokutya ze-FDA. “Ngumsebenzi wethu ukuphikisa amabango abavelisi,” wongeza. "Oko kunokuba nzima ukwenza."

U-Lewis ugxininisa ukuba i-FDA "inomdla kakhulu kwimibandela ephakanyiswe yi-CSPI kwaye iya kwandisa imizamo yokuqinisekisa ukuba izithako zikhuselekile kwaye iilebhile zinyanisekile kwaye zichanekile." Kude kukhutshwe isigunyaziso esisemthethweni, isilumkiso siyacetyiswa.

Izithembiso zokukhutshwa

Musa ukukholelwa yonke into oyifundayo. Ukusuka kwiZiko lezeNzululwazi kuMdla woLuntu, nolu uluhlu lweemveliso ezinokuthi zingabi ngaphezulu kwezibango abathi bazenza:

IiTonics zohlanga Ezi ginseng-, i-kava-, i-echinacea- kunye ne-guarana-ezifakwe kwiiti eziluhlaza "zenzelwe ukubuyisela, ukuvuselela nokuphucula impilo-ntle." Abavelisi bazibhale njengezongezo ukunqanda imithetho engqongqo efunekayo ukuthengisa imveliso yokutya. Le yindawo engwevu. I-CSPI ka-Bruce Silverglade ithi, "Ulawulo lwezoKutya kunye noLawulo lweziyobisi luyekisa ixesha, kodwa hayi rhoqo. Kananjalo unyanzeliso aluyonto iphambili kwi-FDA."

Intloko yobuchopho Le ntshungama iqulethe i-phosphatidyl serine, into efana namanqatha ekhutshwe kwimbotyi zesoya. Imveliso, ebanga ukuba "iphucula uxinzelelo," ithengiswa njengesongezo ngoko ke akufuneki ithobele imithetho ye-FDA elawula ukutya.

IntliziyoBar Ileyibhile ye-snack ye-snack ye-L-arginine enqatyisiweyo inokuthi isetyenziswe "kulawulo lokutya kwesifo semithambo." (I-Arginine i-amino acid efunekayo ukuvelisa i-nitric oxide, i-dilator yegazi.) Ibhalwe njengokutya kwezonyango kusetyenziswa phantsi kweliso likagqirha ukuthintela imithetho yebango lezempilo ye-FDA yangaphambi kwentengiso.

UHeinz Ketchup Iintengiso ziqhayisa ukuba i-lycopene kwi-ketchup "inokunceda ukunciphisa umngcipheko we-prostate kunye nomhlaza womlomo wesibeleko." Inkampani yenza ibango kuphela kwiintengiso kwaye hayi kwiileyibhile ngenxa yokuba iFederal Trade Commission, elawula intengiso, ayifuni bungqina bangaphambili bentengiso yamabango anjalo, ngelixa ibango elinjalo kwileyibhile yokutya aliyi kuvunyelwa yi-FDA ngenxa. ukwenza uphando olungonelanga.

Campbell kaThixo V8 Juice Iileyibhile zithi i-antioxidants kwimveliso "inokudlala indima ebalulekileyo ekucutheni utshintsho olwenzeka ngokuguga okuqhelekileyo," ibango elisekelwe kubungqina besayensi bokuqala. Ijusi nayo iphezulu kwisodium, ekhuthaza uxinzelelo lwegazi oluphezulu kubantu abane-sodium-sensitive, imeko ethi ixhaphake ngokuguga.

Qaphela umthengi: Iingxaki ze-7 ngokutya okusebenzayo

1. Umzi mveliso awukalawulwa. "Abavelisi bokutya bongeza izondlo kunye ne-botanicals ekudleni ngokuzithandela," kusho uMary Ellen Camire, Ph.D., unjingalwazi wesayensi yokutya kunye nesondlo sabantu kwiYunivesithi yaseMaine. Kwiimeko ezininzi, abajonganga ukuba izithako zinokusetyenziswa ngumzimba kule fomu, okanye nokuba ziyingozi okanye ziluncedo. (Enye into ephawulekayo ngabenzi bejusi ye-orange-fortified juice: Ngenxa yokuba i-calcium ifakwe kakuhle xa ithathwa nge-vitamin C, oku kwenza ingqiqo efanelekileyo yokutya.)

2. Akukho zibonelelo ziCetyisiweyo zeMihla yonke. "Amachiza amayeza ngokuqinisekileyo anokuncedisa kunyango oluqhelekileyo," itsho i-CSPI uBruce Silverglade, "kodwa ayizizo ezokutya. Xa uthenga iichips zombona ngekava, awunandlela yokwazi ukuba ungakanani umfuno owufumanayo. IKava inesiphumo sokuthomalalisa. Ukuba umntwana uyityile yonke ibhegi?"

3. Ukuba ikhangeleka njengebha yelekese ... Ukupakisha amashwamshwam ngamayeza kunye nezityholo zezityholo "yindlela yentengiso yokwenza abantu batye ukutya okungenampilo," utshilo uCamire.

4. Ukudlala ugqirha kunokukufaka engxakini. Eminye yemifuno ekuthethwa ngayo yenzelwe ukunyanga iimeko zempilo umthengi angenako kwaye angazivavanyi yedwa. USilverglade uthi: “I-Saint Johnswort ibonakaliswe iluncedo ekunyangeni ukudandatheka. "Wazi njani ukuba uphantsi nje okanye uxinezelekile eklinikhi? Ngaba kufuneka utye isuphu eqinisekisiweyo okanye uye kugqirha wezifo zengqondo?"

5. I-pot-chip binge ingabeka engozini ngaphezu kwesinqe sakho. Sicinga ukuba nantoni na efrijini yethu ikhuselekile ukuba ingatyiwa, kodwa akunjalo koku kutya. "Ukuba uza kuthatha amayeza amayeza, uwathathe njengezongezelelo kwaye udibane nogqirha wakho malunga nokusebenzisana kweziyobisi okunokwenzeka," utshilo uSilverglade. "Ukutya ukutya yindlela engafanelekanga yokufumana idosi efanelekileyo yeyeza."

6. Iimpazamo ezimbini azenzi lungelo. "Awunakho ukusebenzisa ukutya okuqinileyo ukuhlawulela ukungabikho kokutya," utshilo uCamire.

7. Kanye akwanelanga. Iingcali zikrokrela ukuba iifomyula ezininzi ezityetyiswe ngamayeza aziqulathanga ngokwaneleyo izithako ezisebenzayo ukuba zibe nasiphi na isiphumo. Nokuba benze njalo, amayeza onyango kufuneka athathwe kangangeeveki ezininzi ngaphambi kokuba izibonelelo zingene.
