Fluoride: Neurotoxic ntawm txhua qib raws li National Toxicology Program Report; Fluoridation Policy raug hem

International Academy ntawm Oral Medicine & Toxicology (IAOMT) tau ceeb toom rau pej xeem tias tsab ntawv tshaj tawm tau yuam kom National Toxicology Program (NTP) tso tawm lub sijhawm ua haujlwm ntev. tshuaj xyuas ntawm fluoride's neurotoxicity. Sab hauv CDC emails qhia qhov kev tshuaj xyuas raug thaiv los ntawm Tus Pabcuam Kev Noj Qab Haus Huv Rachel Levine thiab zais los ntawm pej xeem txij li lub Tsib Hlis 2022. Daim ntawv tshaj tawm tshiab no tau lees paub thiab ntxiv dag zog rau qhov kev tshawb pom los ntawm ob daim ntawv sau ua ntej tshaj tawm xyoo 2019 thiab 2020. Cov neeg saib xyuas sab nraud txhua tus tau pom zoo nrog qhov kev txiav txim siab tias qhov ua ntej yug menyuam thiab thaum ntxov muaj cov tshuaj fluoride tuaj yeem txo IQ.

NTP tau tshaj tawm 52 ntawm 55 cov kev tshawb fawb pom tias txo qis hauv cov menyuam yaus IQ nrog cov tshuaj fluoride ntxiv.

"Peb qhov kev tshuaj ntsuam xyuas meta tau lees paub cov txiaj ntsig ntawm kev tshuaj ntsuam meta yav dhau los thiab txuas ntxiv lawv los ntawm kev suav nrog cov kev tshawb fawb tshiab, meej dua ... Cov ntaub ntawv txhawb nqa kev sib koom ua ke ntawm cov tshuaj fluoride thiab cov menyuam yaus IQ."

NTP's meta-analysis tso qhov kev puas tsuaj rau hauv kev xav:

"[R] Kev tshawb fawb ntawm lwm cov neurotoxicants tau qhia tias kev hloov pauv hloov pauv hauv IQ ntawm cov pej xeem tuaj yeem muaj kev cuam tshuam loj heev ... 5-point txo qis hauv cov pej xeem IQ yuav ze li ob npaug ntawm cov neeg uas raug cais raws li cov neeg xiam oob khab. "

Cov lus tawm tswv yim los ntawm tsoomfwv tsis muaj npe tau thov tias cov ntaub ntawv tshawb pom tsis siv rau cov dej fluoridation:

"Cov ntaub ntawv tsis txhawb nqa qhov kev lees paub ntawm cov txiaj ntsig qis dua 1.5 mg / L ... tag nrho cov lus xaus hauv daim ntawv no yuav tsum qhia meej tias txhua qhov kev tshawb pom los ntawm cov kev tshawb fawb suav nrog tsuas yog siv rau cov dej fluoride ntau dua 1.5 mg / L."

NTP teb:

"Peb tsis pom zoo nrog cov lus no… peb qhov kev ntsuam xyuas suav txog qhov raug tshuaj fluoride los ntawm txhua qhov chaw, tsis yog dej xwb...vim tias cov tshuaj fluoride kuj pom muaj nyob rau hauv qee yam khoom noj, khoom siv kho hniav, qee yam tshuaj, thiab lwm qhov chaw… Txawm tias nyob hauv lub nroog zoo fluoridated… qib…qhia kom dav sib txawv ntawm cov dej sib xyaw nrog cov tshuaj fluoride los ntawm lwm qhov chaw. "

NTP kuj hais tias:

"Peb tsis muaj lub hauv paus los hais tias peb qhov kev tshawb pom tsis cuam tshuam rau qee tus menyuam yaus lossis cov neeg cev xeeb tub hauv Tebchaws Meskas."

"Muaj ntau qhov kev tshawb fawb zoo tshaj plaws uas qhia IQs qis dua hauv cov menyuam yaus tau ua tiav hauv thaj chaw zoo fluoridated (0.7 mg / L) ... ntau qhov kev ntsuas cov tshuaj fluoride ntau tshaj qhov uas yuav tsum tau los ntawm kev haus dej uas muaj fluoride ntawm 1.5 mg / L."

Nug seb nws qhov kev tshuaj ntsuam xyuas meta puas tau txheeb xyuas cov tshuaj fluoride muaj kev nyab xeeb, NTP tau teb tias lawv pom "tsis muaj qhov pom tseeb" rau tag nrho cov tshuaj fluoride los yog dej fluoride raug. NTP tau hais txog lawv daim ntawv tshaj tawm cov duab qhia qhov kev poob qis hauv IQ ntawm txog 7 cov ntsiab lus dhau ntawm cov tshuaj fluoride ntawm 0.2 txog 1.5 mg / L. Tam sim no muaj lub cev loj ntawm cov pov thawj tshawb fawb los txhawb qhov kev txiav txim siab tias cov tshuaj fluoride tuaj yeem txo tus me nyuam lub IQ, suav nrog cov qib raug los ntawm cov dej fluoridated.

Ib tug neeg txheeb xyuas cov neeg saib xyuas qhov loj ntawm qhov tshwm sim: "...qhov ntawd yog qhov tseem ceeb...Qhov ntawd yog qhov loj."
