Kev siv cov hnab ntim tshuaj yej pheej yig tuaj yeem cuam tshuam tsis zoo rau koj txoj kev noj qab haus huv, raws li kev tshawb fawb tsis ntev los no. Kev tshawb fawb ntawm cov hnab ntim tshuaj yej pheej yig uas suav nrog cov npe nrov tau pom tias lawv muaj cov tshuaj fluorides ntau dhau.

Qhov no ua rau ntau tshaj qhov noj txhua hnub ntawm cov tshuaj no ua rau muaj kev pheej hmoo siab ntawm cov kab mob hniav thiab pob txha.

Cov kws tshaj lij twb tau hu xov tooj rau cov tuam txhab thiab cov khw muag khoom kom muab cov ntaub ntawv muaj tseeb ntawm cov pob tshuaj yej (feem ntau, muaj cov tshuaj fluorides qhia tias yog qhov zoo ntawm cov khoom noj muaj txiaj ntsig ntawm cov tshuaj yej).

Cov xibfwb Paul Lynch thiab Ardhana Mehra, nrog rau kev koom tes ntawm cov tub ntxhais kawm tiav Laura Chen (tag nrho los ntawm University of Derby), piv rau qib fluoride hauv 38 hom tshuaj yej hnab. Siv ion-xaiv electrode tsom xam, uas kuaj pom cov kab hauv cov kua, lawv tshawb xyuas cov qib fluoride. Ua li no, cov kws tshawb fawb, brewed tshuaj yej hnab rau 2 feeb, thiab tom qab ntawd suav cov tshuaj fluoride uas nkag mus rau hauv lub cev los ntawm plaub khob tshuaj yej ib hnub.

Kev poob siab heev rau tus neeg laus noj ntau dua 3.57 mg. fluorine ib hnub twg.

Txawm li cas los xij, txoj kev tshawb nrhiav pom tias qib fluoride hauv plaub khob tshuaj yej tau tshaj li qhov yuav tsum tau ua txhua hnub los ntawm 75-120%. Qhov nruab nrab, plaub lub hnab pheej yig tshuaj yej muaj 6 mg. tshuaj fluorine.

Raws li cov kws tshawb fawb tau sau tseg, muaj qhov sib txawv tseem ceeb ntawm cov tshuaj fluoride hauv cov hnab tshuaj yej pheej yig thiab kim. Tus qauv yog tib yam rau cov tshuaj yej ntsuab thiab dub. Nyob rau tib lub sijhawm, muaj cov tshuaj fluoride tsawg dua hauv cov tshuaj yej ntsuab dua li dub.

Qhov nruab nrab, qhov sib txawv ntawm pheej yig thiab kim tshuaj yej hnab yog 3.3 mg. fluoride ib liter (4 hnab brewed).

Qhov tsawg dua cov tshuaj yej tau ua tiav, qhov tsawg dua fluoride nws muaj. Hom xws li oolong thiab pu'er, nyob rau hauv uas cov tshuaj yej undergoes tsawg industrial processing, muaj tsuas yog 0.7 mg ntawm fluoride. rau 1 liter.

Tsis tas li ntawm qhov pom zoo fluoride noj cov cai yuav hem nrog ntau yam teeb meem kev noj qab haus huv.

Tsis txhob hnov qab tias ntxiv rau tshuaj yej, qhov tseem ceeb ntawm cov tshuaj fluorides muaj nyob hauv cov nqaij nruab deg, qee qhov dej haus, tshuaj txhuam hniav, thiab lwm yam. Qhov tsawg kawg ntawm cov kev phem uas raug hem los ntawm kev nplua nuj ntawm cov kab no yog cov hniav fluorosis - cov tsos ntawm cov xim dawb thiab xim av ntawm cov hniav ntawm cov hniav. Nws kuj yog thawj lub cim ntawm kev noj tshuaj fluoride ntau dhau.

Cov txiaj ntsig txaus ntshai tshaj plaws yog skeletal fluorosis - kab mob uas ua rau cov leeg tsis muaj zog, plab hnyuv, mob pob txha thiab pob qij txha.

Skeletal fluorosis feem ntau tshwm sim nrog kev noj 10 mg lossis ntau dua. fluoride hauv khob rau ntau tshaj 10 xyoo, lossis 2, 5 -5 mg. rau 40 xyoo.

Kev noj tshuaj fluoride ntau ntxiv kuj tseem cuam tshuam nrog kev pheej hmoo ntawm pob txha pob txha, kev pheej hmoo ntawm pob zeb ntau ntxiv (ib yam kab mob rau cov neeg nyob hauv thaj chaw uas muaj cov tshuaj fluoride haus).

Fluoride cuam tshuam rau kev loj hlob ntawm cov pob txha mob cancer hauv cov tub ntxhais hluas. Ib txoj kev tshawb fawb xyoo 1992 tau pom tias qhov kev pheej hmoo ntawm osteosarcoma yog 6.57 npaug ntawm cov neeg uas haus cov tshuaj fluoride.

Laura Chen hais tias "cov nplooj loj hlob ntawm cov tshuaj yej tsob ntoo muaj peev xwm khaws cov tshuaj fluoride," hais tias Laura Chen. "Rau cov tshuaj yej kim, buds thiab nplooj hluas yog siv, thaum lub sij hawm pheej yig dua cov tshuaj yej, cov nplooj loj dua."

"Txawm hais tias fluoride yog ib qho tseem ceeb tshaj plaws micronutrients rau kev noj qab haus huv, nws muaj feem xyuam rau txoj kev loj hlob ntawm cov pob txha thiab kev tiv thaiv ntawm cov hniav lwj, tab sis nws cov ntau dhau yog fraught nrog rau qhov tshwm sim ntawm kev puas tsuaj. Cov neeg uas haus cov tshuaj yej pheej yig hauv hnab, ntxiv rau lwm qhov chaw ntawm cov tshuaj fluoride, tau txais cov tshuaj tua kab mob micronutrient uas ua phem rau lawv txoj kev noj qab haus huv mus ntev."
