Xyoo 1952, Tebchaws Asmeskas kev pabcuam kev noj qab haus huv ntawm Kev kho hniav pej xeem tau tsim ib daim vis dis aus qhia txog kev tsim txiaj ntawm dej fluoridation. Nws tau hais tias: “Cov kws kho hniav hauv ntau lub nroog tau pab coj cov txiaj ntsig ntawm fluoridation rau cov menyuam yaus. Tam sim no peb cov menyuam tuaj yeem muaj kev noj qab haus huv zoo dua los ntawm cov dej fluoridated. "

Tab sis tom qab 78 xyoo tau hais tias cov tshuaj fluoride hauv peb cov dej yog cov txiaj ntsig kev noj qab haus huv rau peb, kev tshawb fawb tau ua pov thawj tias tsis muaj tseeb. Hmoov tsis zoo, nws yog qhov rov qab - fluoride hauv peb cov dej ua tau ua rau puas hlwb puas tsuaj.

Lub National Toxicology Program, ib feem ntawm Kev Noj Qab Haus Huv thiab Kev Pabcuam Tib Neeg, tsis ntev los no tau tshaj tawm tsab ntawv tshaj tawm: "Lub Xeev Kev Tshawb Fawb Txog Fluoride Exposure thiab Neurodevelopmental and Cognitive Health Effects: A Systematic Review".

Lawv daim ntawv tshaj tawm, uas tau txheeb xyuas 52 tus phooj ywg txheeb xyuas cov kev tshawb fawb los ntawm thoob plaws ntiaj teb, pom tias kev noj tshuaj fluoride txuas rau lub hlwb tsis zoo hauv cov menyuam mos.

Cov kev tshawb fawb tseem pom tias muaj kev tsis txaus siab txog kev xav tsis zoo thiab IQ qis dua hauv cov menyuam mos yug los rau cov niam uas tau haus dej fluoridated thaum cev xeeb tub thiab cov menyuam mos noj cov mis sib xyaw nrog fluoridated kais dej.

Txawm hais tias cov kws tshaj lij fluoridationists tau sim ua kom tsis zoo rau daim ntawv tshaj tawm no, txawm tias mus deb li qhov tsis raug lees paub tias tag nrho cov kev tshawb fawb tau "debunked", NTP tau hais tias lawv tsuas yog tshuaj xyuas cov kev tshawb fawb zoo uas ua tiav cov txheej txheem kev tshawb fawb meej nrog kev tswj hwm thiab suav nrog. rau txhua qhov sib txawv.

Raws li Fluoride Action Network, tus thawj coj tam sim no tau koom nrog hauv thaj chaw fluoridation lub tsev hais plaub tawm tsam EPA, NTP cov ntaub ntawv yog cov kev tshuaj xyuas ntau tshaj plaws thiab tshawb fawb NTP daim ntawv tshaj tawm hauv keeb kwm.

Internal CDC emails nrhiav tau los ntawm Txoj Cai Lij Choj Ntawm Cov Ntaub Ntawv thov los ntawm Fluoride Action Network qhia tias Kev tshaj tawm ntawm NTP tsab ntawv ceeb toom kawg raug txwv vim muaj kev cuam tshuam los ntawm Tus Pabcuam Kev Noj Qab Haus Huv, Rachel Levine.

Nws poob siab tias qhov kev tshaj tawm tsab ntawv tshaj tawm no, raug txwv los ntawm HHS thiab lwm lub koomhaum tseemfwv uas txhawb nqa dej fluoridation, thiab tsuas yog tso tawm tom qab ib qho lub tsev hais plaub tau txais tsab ntawv ceeb toom.

Qhov kev tso tawm ntawm tsab ntawv ceeb toom no thiab nws cov kev tshawb pom yog ib qho kev yeej loj rau kev noj qab haus huv ntawm txhua tus tib neeg uas tsis tas yuav raug tshuaj fluoride thiab cov neeg tawm tsam tawm tsam kev ua phem ntawm cov dej fluoridation vim nws ua rau peb ib kauj ruam los ze zog kom xaus kev siv tshuaj yuam hauv peb haus. dej.

Thiab rau cov uas xav paub tias lawv tuaj yeem tiv thaiv kab noj hniav yam tsis muaj kev pheej hmoo ntawm cov tshuaj fluoride, tsis txhob hnov ​​​​qab, tsis muaj dab tsi ua rau lub qhov ncauj huv si - txhuam hniav thiab txhuam koj cov hniav txhua hnub tsawg kawg yog ob feeb, noj zaub mov zoo uas suav nrog zaub ntau, rog zoo thiab muaj protein ntau thiab tau kawg txo koj cov piam thaj noj.
